Description

technical field

The present invention relates to a system for forming a support structure for a car body of a vehicle, in particular a rail vehicle, and such a support structure. Furthermore, a car body is described, which is provided at least in part with the help of such a system.

Known prior art

It is known that support structures for vehicle bodies, in particular rail vehicles, are assembled using different profiles. Such profiles are semi-finished products that can preferably be produced by extrusion. During the construction process, an individual concept with a large number of different profiles is defined for each type of car body. Accordingly, it is necessary to examine and select each individual profile with regard to maximum and permanent mechanical load capacity, suitability with regard to environmental conditions, design aspects, costs, etc.

For example, from the WO 2013/077192 A1 a body of a railway vehicle is known, which consists of a base frame, a side body structure, a gable end body structure and a roof body structure, inside of which an interior material is provided which has the function of improving the heat and sound insulation as well as the construction. By welding different profiles together in a transition area between the roof body structure and the side body structure, a corresponding connection point is defined between the side and the roof, or between the side and the floor.

Disadvantages of the Prior Art

Such constructions of car bodies of rail vehicles must always be designed in detail in a final position and calculated with regard to the requirements. This applies in particular to the semi-finished products used for this.

problem

An object of the present invention is therefore to provide a system for forming a supporting structure of a car body, which facilitates the design process and the selection of semi-finished products, in particular wherein an effort of defining a supporting structure of a car body is reduced, the car body having a simple and robust Has structure and at the same time brings an improvement in the design possibilities and the effort involved in designing a vehicle or a vehicle platform.

Solution according to the invention

The above object is achieved by a system for forming a support structure of a car body of a vehicle, in particular a rail vehicle, according to claim 1 and by a support structure having such a system according to claim 12. Alternatively or additionally, a car body with the above support structure according to claim 14 and a vehicle having such a car body according to claim 15 are proposed for solving the task.

The system has a profile element and a profile component that can be connected to it to form the supporting structure. The support structure is formed by connecting the profile element and profile component to one another by welding. The supporting structure can have a multiplicity of profile elements and profile components connected to one another by welding, riveting and/or screwing, so that the supporting structure forms the car body at least in part.

According to one embodiment, the profile component and/or profile element are to be regarded as equivalent and/or interchangeable with regard to a technical function. In particular, the use of the different terms “profile element” and “profile component” also serves the purpose of being able to differentiate them in the description of the present disclosure. Additionally or alternatively, however, a first profile element, a second profile element, a further profile element and/or a first, second, further profile component could also be spoken of in this context.

The profile element thus has an element profile direction which extends in an element profile axis. Perpendicular to this, an element profile plane can be defined with an element vertical axis running therein and a corresponding element vertical direction and with an element transverse axis running in the plane and a corresponding element transverse direction.

With regard to the element profile level, the profile element can be subdivided into an element connection section and an element body adjoining it. The element connection section is designed to have a welded connection with the profile component and/or to be able to form, enter and/or carry another (additional) profile element or component.

In the area of the element connection section, the profile element has - in relation to the element profile plane - a first element stop, a first welding bevel, a second element stop and a second welding bevel, in particular in the transverse direction of the element and/or in the element A first element gas pocket is provided between the first element stop and the first welding bevel and/or a second element gas pocket is provided between the second element stop and the second welding bevel.

An element contour of the profile element is thus designed in the element profile plane in such a way that the first element stop is arranged adjacent to the first welding bevel. In particular, the first element stop is adjacent to the first element gas pocket, which in turn is adjacent to the first weld bead. In particular, an element surface of the profile element is designed in such a way that a surface section of the first element stop - if necessary by performing an angle or a bend - merges into a surface section of the first element gas pocket, whereby this in turn - if necessary by performing an angle or a kinking - continues to merge into a surface portion of the first weld bevel. Correspondingly, the first element gas pocket can be provided lying in the element profile plane between the first element stop and the first welding bevel. The foregoing applies either alternatively or additionally to the second element stop, to the second weld bevel, and optionally to the second element gas pocket.

Due to the nature of the profile element as a profile-like semi-finished product, the first element stop, the first element gas pocket and the first element welding bevel, and/or the second element stop, the second element gas pocket and the second element welding bevel extend at least over part of a total length in the profile direction of the profile element, for example over more than 50% of the total length, preferably completely over the total length.

The profile component also has a component profile direction that extends in a component profile axis. Perpendicular to this, a component profile plane can be defined with a component vertical axis running therein and a corresponding component vertical direction and with a component transverse axis running in the plane and a corresponding component transverse direction.

At a component connection section in the component profile plane, the profile component has a first component radius surface with a first component radius and a second component radius surface with a second component radius. The component connection section connects to a component body and is used to form a welded connection to the profile element and/or to an additional profile element.

Preferably, the first component radius and the second component radius are curved in the same direction in the component profile plane, so that the component radii in the component connection section are both convex or both concave with respect to the component body. In particular, the component connection section can be designed as a rounded, preferably part-circular, outer surface which forms and/or carries the first component radius surface and the second component radius surface.

Additionally or alternatively, the profile component is designed in such a way that the first component radius surface, the first component radius, the second component radius surface, the second component radius and/or other component radius surfaces, component radii, connecting sections extend over at least one Part of an overall length in the component profile direction of the profile component, for example over more than 50% of the overall length, preferably extending/extending completely over the entire length.

In particular, the surface details described in the context of the present disclosure are specific shapes, bulges, protrusions, corners, curves, radii and/or other two-dimensional geometric features of the profile element, the profile component and/or other profile elements, profile components and/or additional profile elements preferably and in particular lying exclusively in a respective profile plane, in particular with regard to a respective profile cross-section.

Furthermore, both the first element stop and the second element stop are provided on the element connection section, and the first component radius surface and the second component radius surface are provided on a component connection section of the profile component in such a way that the profile element and the profile component can assume a plurality of different relative positions, each with an individual angle between the vertical axis of the element and the vertical axis of the component, forming a body contact that is at least statically determined. The first weld land then forms a first weld notch with the first component radius surface for a first weld seam, and the second weld land forms a first weld notch with the second component radius surface second weld notch for a second weld. In particular, the first welding notch and the second welding notch are aligned in the element/component profile direction and extend in particular over a significant part, preferably over at least 30%, in particular over at least 50%, more preferably over at least 70%, of the profile length of the profile element and of the profile component.

The majority of the different relative positions unites on the one hand - and is achieved by the fact that the element profile direction and the component profile direction are aligned the same and together in order to achieve a statically at least determined body contact. The profile element and the profile component can consequently be aligned in such a way that the element profile axis and the component profile axis run parallel to one another, in particular are aligned and coincide.

On the other hand, the majority of the different relative positions are made possible by the fact that the first element stop with the first component radius surface and the second element stop with the second component radius surface each enter into contact subject to normal forces. In addition to the common orientation in the profile direction, the element connection section and the component connection section can be pressed against one another. By providing a normal force for this - the profile element is pressed against the profile component - the first element stop rests against the first component radius surface and the second element stop against the second component radius surface. Now that a desired and/or predetermined relative position of the profile component and profile element is defined and assumed by the at least statically determined contact, the desired relative position of Profile element and profile component are permanently fixed to each other.

The term "at least statically determined" is to be understood in such a way that - if there is a sufficient normal force - the profile element and profile component cannot slip and/or wobble relative to one another. In particular, the normal force between the profile element and profile component is selected such that the resulting adhesive force between the respective surfaces of the stops and the respective contact surfaces prevents slipping in the component/element transverse direction, component/element vertical direction and/or in the component/element profile direction is prevented. A person responsible for assembling the profile element and profile component is able to determine and apply the necessary forces. If necessary, such a person would be able to identify and use the tools necessary to establish such a normal force (e.g. screw clamps, suitable clamps). The said person would also ensure that no unusual relative forces, in particular acting in the component/element transverse direction, component/element vertical direction and/or in the component/element profile direction, can act on the profile element and/or profile component, so that the previously defined static at least certain relative position of profile element and profile component is dissolved or changed.

According to one embodiment, the element connecting section forms a kind of hinge, joint and/or rotational guide via the element stops for the component connecting section such that the profile component is rotatably mounted in the element connecting section around a profile axis—vice versa .

The embodiment described above makes it possible for the first time to present a support structure having a profile element and a profile component with different alignment configurations, with the same types and/or embodiments of semi-finished products, in particular profile elements and/or profile components, being able to be used in each case. In particular, it enables several different positions within support structures to be mapped using the same semi-finished products. This reduces the number of semi-finished products and allows different boundary conditions when developing different platforms for car bodies. For example, the profile element and profile component can represent a first supporting structure, with the profile element and profile component in a first relative position—related to the element/component profile plane—being able to be aligned with one another and welded. The first supporting structure formed in this way can now form a first section, for example a floor or a roof of the car body. If, on the other hand, the profile element and profile component are aligned and welded to one another in a second relative position, a second supporting structure formed as a result can form a second section, for example a floor or a roof of the car body. Furthermore, for example, the relative positions described above differ in that the element vertical axis in the first relative position and the element vertical axis in the second relative position to each other - based on the element / component profile level, and assuming the component vertical axis was used as an unchangeable reference Axis assumed - are inclined and each include a different first angle and second angle.

In this way, the advantage is achieved for the first time that the same type of profile element and profile component can be used as a standard component for forming different supporting structures, in particular different supporting structures with different angles. This is accompanied by a reduction in the testing effort for semi-finished products for creating different support structures.

According to one embodiment of the above exemplary embodiment, it is disclosed that the element connection section and/or the component connection section is designed in such a way that the first welding notch and the second welding notch are spaced apart from one another with a profile welding distance, in particular with the profile welding distance being at least 20 mm, in particular at least 30 mm, preferably at least 50 mm and/or at least 50%, in particular at least 80%, preferably at least 100% of an element width of the profile element and/or a component width of the profile component. In particular, the profile welding distance is determined by the arrangement and an associated distance between the first component radius surface and the second component radius surface and/or by the arrangement and an associated distance between the first element stop and the second element stop.

According to a further embodiment, the system can have an additional profile element, so that a support structure formed therewith is formed by at least one profile element, a profile component and the additional profile element. The additional profile element has - in particular analogously to the profile element - an additional element profile direction with an additional element profile axis, an additional element profile plane extending perpendicularly thereto, an additional element transverse direction running therein with an additional element transverse axis extending in this respect, and one in the Additional element profile plane running additional element vertical direction with an additional element vertical axis extending in this regard.

Furthermore, the additional profile element is connected to an additional element connection section with a first additional element stop, a first additional element welding bevel, in particular with a first additional element gas pocket arranged between the additional element stop and the additional element welding bevel, and with a second additional element stop, a first additional element welding bevel, in particular equipped with a first additional element gas pocket arranged between the additional element stop and the additional element welding bevel. In particular, the configuration of the additional element connection section described above is analogous to and/or partially identical to the element connection section of the profile element described above.

In addition to the provision of the additional profile element, the profile component is designed with a further component connection section, which - analogously to the previously described component connection section - has a third component radius surface running perpendicular to the component profile plane with a third component radius and one also perpendicular extending fourth component radius surface having a fourth component radius.

The additional element connection section and the further component connection section are designed in such a way, in particular both the first additional element stop and the second additional element stop are designed and provided in this way on the additional element connection section, and the third component radius surface and the fourth Component radius surface is designed and arranged on the further component connection section in such a way that the additional profile element and the profile component have a plurality of different relative positions to one another, each with an individual angle between the vertical axis of the additional element and the vertical axis of the component, forming at least a statically determined body contact, can take, the first additional element welding bevel with the third component radius surface a third weld notch for a third weld seam and the second additional element weld bevel with the fourth component radius surface a fourth weld notch for a four te weld seam. In order to achieve this, the additional profile element and the profile component can be jointly aligned, in particular aligned, with regard to the additional element profile direction and component profile direction, and contacting of the first additional element stop and the third component radius surface and of the second additional element stop and fourth component radius surface is set up. The achievement of a defined but adjustable relative position and the at least statically determined physical contact between the additional profile element and the profile component takes place analogously to the establishment of the previously described physical contact between the profile element and the profile component; Accordingly, details of the above disclosure in this regard can be transferred to the connection between the additional profile element and the profile component.

The present exemplary embodiment makes it possible for the profile element to be able to be connected to the first and the second element stop via the profile component with the additional profile element. The support structure formed in this way is at least made of the profile element, the Additional profile element and the intermediate profile component formed.

Profile element and profile component are carrier-like semi-finished products, preferably produced from an aluminum alloy by means of an extrusion process, and thus each have a profile direction in which the structure of the respective profile element and/or profile component is essentially unchangeable. A respective profile element and/or profile component has an identical cross section in the profile direction.

Profile element, profile component, possible additional profile elements and/or additional profile components can be, for example, a profile-like support element with an inner lattice structure, in particular a complex one.

Additionally or alternatively, it is conceivable that the profile element, profile component, possible additional profile elements and/or additional profile components is designed as a tube, strip, semi-finished product with an at least partially circular or ring-shaped cross section, or L, T, I beam/ are.

Profile element, profile component, possible additional profile elements and/or additional profile components are preferably designed as double-walled extruded profiles made of an aluminum alloy. A double wall can be achieved by providing essentially continuous wall regions running essentially in the vertical direction. These wall areas, which can be described as profile walls, delimit a corresponding profile in the corresponding transverse direction. In this context, the term “essentially continuous” means that these wall regions run continuously, but in particular interruptions such as bores, recesses, incisions are possible.

According to one embodiment of the above exemplary embodiment, it is disclosed that the profile component is designed in such a way, in particular that the first and third component radius surfaces and/or the second and fourth component radius surfaces are arranged in such a way that the first welding notch and the third welding notch and/or the second welding notch and the fourth welding notch are spaced apart from one another by a supporting structure welding distance, in particular the supporting structure welding distance being at least 20 mm, in particular at least 30 mm, preferably at least 50 mm and/or at least 50%, in particular at least 80%, preferably at least 100 % of a component width of the profile component. In particular, the support structure welding distance is determined by the arrangement and an associated distance between the first and third component radius surface and/or the second and fourth component radius surface.

As an alternative to the above exemplary embodiment - having the profile element, the profile component and additional profile element, the profile component having a first and second radius surface for contacting by the first and second element stop of the profile element and for forming the first and the second welding notch for the first and the second weld seam, and wherein the profile component also has a third and fourth radius surface for contacting by the first and second additional element stop of the additional profile element and for forming the third and fourth weld notch for the third and fourth weld seam - becomes an inverse design principle proposed the system for forming the support structure with a profile element, profile component and an additional profile component:

The additional profile component has an additional component profile axis extending in an additional component profile direction, an additional component profile plane extending perpendicularly thereto, and an additional component vertical axis running therein, a first additional component running perpendicular to the additional component profile plane on a first component connection section -Radius surface with a first additional component radius, a second additional component radius surface with a second additional component radius.

Furthermore, the profile element according to the inverse embodiment has a third element stop, a third welding bevel, and in particular a third gas pocket arranged in between, a fourth element stop, a fourth welding bevel, and in particular a fourth gas pocket arranged in between on. Consequently, the profile element is designed to connect the profile component and the additional profile component to one another, with respective stops being provided on the profile element for contacting corresponding radii surfaces of the profile component and the additional profile component.

Stops and radius surfaces are - analogous to the previous embodiment - arranged and designed in such a way that, by means of joint alignment of the additional component profile direction and element profile direction, and by means of contacting of the third element stop and first additional component radius surface and of the fourth element Stop and second additional component radius surface, the additional profile component and the profile element have a plurality of different relative positions to one another, each with an individual angle between the vertical axis of the additional component and the vertical axis of the element, forming a statically at least determined body contact, with the third welding bevel having a third welding notch with the first additional component radius surface for a third weld seam and the fourth welding bevel with the second additional component radius surface having a fourth welding notch for form a fourth weld. It is explicitly disclosed that the modes of action and preferred arrangements of the exemplary embodiments described above can be transferred to the present inverse exemplary embodiment, so that it is conceivable, for example, to set a supporting structure welding distance of the additional profile component of the present inverse exemplary embodiment according to the supporting structure welding distance of the additional profile element perform the embodiment described above.

According to a further, independent embodiment, at least one of the welding notches, in particular all of the welding notches, is designed for introducing a V or HV weld seam. Additionally or alternatively, at least one of the welding notches, in particular all welding notches, encloses an angle of more than 10°, in particular more than 30°, preferably more than 50°, and/or not more than 100° between the respective welding bevel and the respective radius surface, in particular no more than 70°, preferably no more than 60°. The angle should preferably be measured at the base of the corresponding welding notch.

In particular, the welding notches are designed in such a way that there is no butt portion in the sense of a butt or HY seam and/or that the welding notch enables a butt seam.

Furthermore, it is disclosed that at least one element, component, additional element and/or additional component stop, in particular all stops, is designed in such a way that at least one of the welding bevels, in particular all welding bevels, has a width of more than 2 mm, in particular more than 3 mm , preferably more than 4 mm, and/or no more than 15 mm, in particular no more than 12 mm, preferably no more than 10 mm. This makes it possible to provide a sufficiently strong material connection between the profile element, profile component, additional profile element and/or additional profile component for power transmission.

According to a specific embodiment, the element connection section, the component connection section, the additional element connection section and/or the further element connection section is/are designed in such a way that at least one of the welding notches, in particular all of the welding notches, is open towards a supporting structure surrounding the supporting structure /are. In particular, this is achieved by arranging at least one of the stops, in particular all stops and at least one of the welding bevels, in particular all welding bevels, on the respective stops in such a way that they are aligned towards the surroundings of the support structure. Such an orientation is present when a person located in the vicinity of the support structure can look at a welding bevel from a viewing angle of at least 30°, in particular at least 60°, preferably at least 70°. The viewing angle is defined between the alignment of the surface of a respective welding bevel (related to a respective cross-section) and a line of sight between the person and the welding bevel.

The described configuration of the welding notch(s) and/or the welding bevel(s) enables accessibility for welding in the respective welding notch.

At least one welding bevel, in particular the first welding bevel and the second welding bevel of the profile element, preferably all welding bevels, can be formed on profile walls and/or in each case by a profile wall.

The term "support structure environment" describes a space outside of the support structure that is or is to be formed, in particular with a minimum distance from the support structure of at least 50% of an element width, a component width or an additional element width.

According to one configuration, the first component radius and the second component radius and/or the third component radius and the fourth component radius, in particular all component radii, have an identical component center point. Accordingly, the component connection section forms a circular outer contour with a constant radius that remains essentially the same, at least in the area of the component surfaces. The first component surface and the second component surface and/or the third component surface and the fourth component surface lie on the circular outer contour.

In this way, the body contact between profile element and profile component, and/or between profile component and additional profile element, and/or profile element and additional profile component is improved in different relative positions. In particular, this avoids during the setting of the desired relative position that an undesired relative displacement of profile element and profile component, of profile component and additional profile element, and/or of profile element and additional profile component in the transverse direction of the element partial transverse direction, and / or in additional element / additional component transverse direction.

According to a further improved embodiment, the first element stop has a first element radius and the second element stop has a second element radius, the first element radius and the second element radius preferably having an identical component center point. Optionally, the component radii and the corresponding element radii all have the same component center point. In particular, the presence, arrangement and/or formation of the contacting stop(s) with a corresponding element or component radius surface(s) or additional element or component radius surface(s) for the purpose of forming the statically at least determined to make physical contact. For example, the first element stop and the second element stop can be formed jointly and/or integrally by means of a single element radius surface comprising the first element radius surface and the second element radius surface. In this case, a first portion of the common radius surface forms the first element stop with corresponding element first radius surface, and a second portion of the common radius surface forms the second element stop with corresponding second element radius surface. In particular, this means that the conceptual differentiation as "first stop", initial sign on second stop", "first surface" and "second surface" is not necessarily to be understood as a physical differentiation, rather the first and second of the corresponding areas/components/ Components / elements may be integrally formed in one piece.

According to a further embodiment, the first component radius surface and the second component radius surface are provided integrally on the same area of the component connection section such that they merge into one another and together represent a continuous, uninterrupted component radius surface. This measure increases the stability of the connecting section.

In the course of an additional embodiment, it is disclosed that the third component radius surface and the fourth component radius surface are also provided integrally in the same area of the further component connection section, so that they merge into one another and together represent a continuous, uninterrupted component radius surface. In this way, all component radius surfaces lie on a continuous surface of the profile component connecting the profile element and the additional profile element, the overall stability of the supporting structure formed thereby being increased.

In addition to and/or entirely as an alternative to the above embodiments, the component radius surfaces are provided on different, separate areas of the component connection section and/or the further component connection section, so that the radius surfaces do not merge into one another and an interrupted, represent the entire component radius area. In this way, for example, an overall weight of the support structure can be reduced and/or accessibility to an interior of the profile element and/or the profile component can be made possible.

In addition, it is described that the first component radius and the second component radius are both convex with respect to a component body of the profile component, and in particular the first component radius and the second component radius are both concave. In this way, a range for adjusting a relative position is easily expanded.

According to one embodiment, the first component radius, the second component radius, the first element radius, the second element radius, the third component radius, the fourth component radius, the first additional element radius is or are the second Additional element radius, the first additional component radius, and/or the second additional component radius at least 40%, in particular at least 100%, preferably at least 300% and/or at most 10000%, in particular at most 2000%, preferably at most 1000%, of an element -Width of the profile element, a component width of the profile component, an additional element width of the additional profile element, and/or a component width of the additional profile component. In particular, if a radius is significantly larger than a component width, it can be achieved in this way that a respective weld seam is particularly well defined and/or smoothing out the respective weld seam results in a particularly clear contour.

According to a preferred embodiment, the additional component connection section of the profile component is located opposite the (first) component connection section—relative to the component profile plane—in the direction of the component vertical axis. The profile component is thus designed in such a way that, based on the component vertical axis, a welded connection can be made to the profile element on one side of the profile component and a connection to the additional profile element can be provided on the opposite side of the profile component. In this way, the profile component functions as a position-variable connection component between the profile elements. The component radius surfaces can all be provided together on a continuous, uninterrupted surface of the profile component, so that they form a merging, common, continuous, and uninterrupted component radius surface.

According to a further embodiment, it is even conceivable that the profile component has a closed oval, ring-shaped or circular outer contour. In the case of a circular outer contour, the profile component appears as a tube in terms of its outer shape.

Irrespective of whether the profile component is oval, ring-shaped or circular in shape, an internal structure for strengthening and/or stiffening can be advantageously provided. For example, internal webs (internal ribbing) can be connected to an outer contour of the profile component from the inside in the area of one or all component radius surfaces, so that favorable force application points are provided and an advantageous flow of force through the profile component is made possible.

The above-described internal structures for strengthening and/or stiffening can also be provided for the profile component or for the profile element.

According to one embodiment, the profile element, the profile component, the additional profile element, and/or the additional profile component have a similar width extension in the respective transverse direction. In particular, an element width of the profile element differs from a component width of the profile component, and/or element width from an additional profile element width, and/or component width from the additional profile element width by no more than 30% , in particular by no more than 20%, preferably by no more than 10%. This relates in particular to a width of the respective components in the area of a respective connection section.

Furthermore, a supporting structure of a car body of a vehicle, in particular a rail vehicle, is disclosed, wherein the supporting structure is formed by at least one profile element and by a profile component welded thereto. In particular, the support structure has at least one or a large number of systems according to one or a combination of the above exemplary embodiments, the profile element and the profile component being formed by applying the first weld seam in the first weld notch and by applying the second weld seam in the second weld notch according to the first relative position or the second relative position are welded together.

Furthermore, it is conceivable that the support structure has a profile component, a profile element and an additional profile element. The profile element is welded to the profile component, and the additional profile element is also welded to the profile component by providing a third weld seam in the third weld notch and a fourth weld seam in the fourth weld notch.

According to another aspect, a body for a vehicle is disclosed. This car body has, for example, a floor that is constructed using at least one support structure according to one of the preceding exemplary embodiments. Such a floor can in turn have recesses for accommodating bogies or drive components, with corresponding height differences in the longitudinal direction of the vehicle or in the transverse direction of the vehicle and corresponding walls being constructed using a support structure according to one of the preceding exemplary embodiments. Furthermore, walls of the vehicle running in the transverse direction or in the longitudinal direction can be represented with the aid of support structures according to one of the above exemplary embodiments.

According to one embodiment, the car body is not made of and/or is not made with the help of steel profiles and/or essentially has no steel profiles. In this context, the term "essentially" means that no essential supporting elements, supporting structures, carriers and/or other structure-forming components, or components of such, are/are made from and/or with the aid of steel profiles and/or have/have them. Preferably, this exclusion does not apply to fasteners such as screws and/or rivets.

According to a preferred embodiment, the supporting structure and/or supporting structures of the car body are essentially made entirely of aluminum alloys. In this context, the term “essentially” means that essentially all of the essential supporting elements, supporting structures, carriers and/or other structure-forming components, or parts thereof, are/are made from at least one aluminum alloy.

The system for forming the supporting structure shows its conceptual strength here, since a large number of different components, units, walls, roof areas, troughs, recesses and/or other components and areas of the car body can be replaced by essentially the same types of semi-finished products (profile element, profile component, additional -Profile element, additional profile component) can be represented by corresponding Semi-finished products can be welded to each other in different positions.

The embodiments described above can be combined with one another as desired, but in a sensible manner, with some supporting structures of the car body being formed by only one profile element and one profile component, but other supporting structures being formed by a profile element, an additional profile element and a connecting profile component.

exemplary embodiments

To clarify the overall understanding, 1 a rail vehicle 100 is shown. This has two wagons which are coupled to one another in a longitudinal direction 103 and each have a wagon body 102 which are mounted on bogies 101 so that they can be rolled on rails. The car bodies 102 have a head structure 111 and/or an end wall 112 at end regions in the longitudinal direction 103 .

2 shows a partial section through a car body 102. A floor 108, a wall 106, and a roof 107 are constructed from profile elements 20, from profile components 40 and from additional profile elements 60, 80 and 81. According to the present example, an element profile direction 22 of profile element 20, a component profile direction 42 of profile component 40, an additional element profile direction 62 of additional profile element profile elements 20 and profile directions in further additional profile elements 80 and 81 extend essentially in longitudinal direction 103 of car body 102. However, it is also conceivable for a profile element or a profile component to be installed in car body 102, at least partially aligned in a car body transverse direction 105, with a respective profile axis at least partially in a vertical direction 104 and/or in a car body transverse direction 105 runs.

In 2 an additional profile element 60 acting as floor 108, a profile element 20 and a connecting profile component 40 form a first support structure 2 of car body 102. This support structure 2 implements a transition from floor 108 to a lower part of wall 106 of car body 102.

Further supporting structures 2 are provided in a transition from the lower part of the wall 106 into an additional element 80 of the side wall and in a transition from the additional element 80 of the side wall into a further additional element 81 of the roof 107 . Individual profile elements 20, connecting profile components 40 and additional profile elements 60, 80 and 81 are sometimes used.

3 until 6 show a first embodiment of a support structure 2 in a schematic manner. In this case, a profile element 20 is connected to a profile component 40 at an angle 5 according to a first relative position 3 . For example, such a supporting structure 2 can be used to construct the side wall 106 of the car body 102 . In order not to unduly complicate the legibility of the figures, not all reference numbers in each of the 3 until 6 recorded.

The support structure 2 according to 3 until 6 consists of a profile element 20 and a profile component 40 welded thereto. The profile element 20 and the profile component 40 are aligned with one another with respect to their profile axes 22 and 42 . A vertical axis 25 of the profile element 20 encloses the angle 5 with a vertical axis 45 of the profile component 40 .

The reference number 3 here represents a first and realized relative position 3 of profile element 20 and profile component 40 and coincides with the vertical axis 45 in the drawing. Reference number 4 represents a further possible relative position 4 of profile element 20 and profile component 40. Both relative positions 3 and 4 have in common that a statically at least determined body contact is established between profile element 20 and profile component 40.

assistance 5 and 6 are constructive details of the profile element 20 ( 6 ) and the profile component 40 ( 5 ) outlined. The profile component 40 has a component profile axis 43 aligned in the component profile direction 42 . A component profile plane 44 can be defined perpendicularly to the profile axis 32, in which the cross-sectional representations of the profile component 40 according to FIG 4-6 lie. The component vertical axis 45 runs in the component profile plane 44, forming a corresponding component vertical direction, and a component transverse axis, forming a component transverse direction 46.

The profile component 40 is a semi-finished product extending in the profile direction 42 with a component body 58 and an adjoining component connection section 41. The profile component 40 has a lattice structure with internal ribbing 84 comprising webs on the inside. The component connection section 41 has a rounded outer contour for forming a first component radius surface 47 and a second component radius surface 49 which are used to contact element stops 32 and 33 of the profile element 20 . The first component radius surface 47 is convexly bent with a first component radius 48 with respect to the component body 58 around the component center point 51 and the second component radius surface 49 is with a second component radius 50 with respect to the component Body 58, convexly bent around the component center 51.

Also that in 6 The profile element 20 shown has an element profile direction 22 and an element profile axis 23 lying therein, it being possible for an element profile plane 24 to be defined perpendicular thereto. Therein runs the element vertical axis 25, defining an element vertical direction, and an element transverse direction 26, defining an element transverse axis.

The profile element 20 comprises an element body 38 with an internal ribbing 82 and corresponding webs and an element connection section 21 for entering into a statically at least certain body contact with the profile component 40. For this purpose, the profile element 20 in the area of the element connection section 21 has a first element Stop 32, a first welding bevel 34 and in particular a first gas pocket 36 lying therebetween. Furthermore, a second-element stop 29, a second welding bevel 35 and in particular a second gas pocket 37 lying between them are provided.

The contour of the profile element 20 in the element profile level 24 can be described as follows: The first element stop 32 is adjacent to the first element gas pocket 36 and this in turn is adjacent to the first welding bevel 34. In particular, an element surface of the Profile element 20 designed in such a way that a surface section of the first element stop 32, while performing an angle or a bend, transitions into a surface section of the first element gas pocket 36, which in turn, while performing an angle or a bend, continues into a surface section of the first welding bevel 34 transforms. In particular, the first welding bevel 34 is arranged further outward than the first element stop 32 with respect to an area surrounding the profile component 20 and thus also a supporting structure area 14 . The first element stop 32 is therefore closer to the vertical axis 25 than the first welding bevel 34.

The arrangement of the first element stop 32, the first gas pocket 36 and the first welding bevel 34 corresponds analogously to the arrangement of the second element stop 33, the second gas pocket 37 and the second welding bevel 35.

The first element stop 32 has a first element radius surface 27 curved with a first element radius 28 about an element center point 31 for contacting the first component radius surface 47 of the profile component 40 . Analogous to this, the second element stop 33 is provided with a second element radius surface 29 which is bent with a second element radius 30 around the element center point 31 .

Assembled and welded together, the profile element 20 and the profile component 40 form the support structure 2 ( 3 and 4 ), wherein the profile element 20 and profile component 40 can assume the different relative positions 3 and 4 with respect to an alignment of the element vertical axis 25 and the component vertical axis 45, but also other relative positions. The plurality of different relative positions 4 and 5 are made possible in that the first element radius surface 27 of the first element stop 32 with the first component radius surface 47 and the second element radius surface 29 of the second element stop 33 with the second component Radius surface 49 each enter into a contact subject to normal force. In addition to the common alignment in profile directions 22 and 42, the element Connection portion 21 and the component connection portion 41 pressed against each other. As a result, the first element stop 32 contacts the first component radius surface 47 and the second element stop 33 contacts the second component radius surface 49 . Since the relative position 3 or 4 is now defined and assumed by the at least statically determined contact, the first welding bevel 34 forms a first welding notch 6 with the first component radius surface 47 for a first weld seam 8 ( 3 ) and the second welding bevel 35 forms a second welding notch 7 with the second component radius surface 49 for a second weld seam 9 ( 3 ) out.

To establish the position-variable connection of profile element 20 and profile component 40, the element connection section 21 forms a kind of articulated guide via the element stops 32 and 33 for the round component connection section 41, so that the entire profile component 40 is in the element connection section 21 can pivot about a component profile axis, in particular about the element center point 31 and/or the component center point 51 - depending on the perspective, the profile element 20 can be pivoted about the component connection section 41.

The element connection section 21 and the component connection section 41 are formed in such a way that at least the first welding kerf 6 and the second welding kerf 7 are opened toward the supporting structure surroundings 14 . For this purpose, the stops 32 and 33, the welding bevels 34 and 35 and the component radius surfaces 47 and 48 are arranged on the respective connecting sections 21 and 41 in such a way that a person in the vicinity of the support structure can see the area with a viewing angle of at least 30°, in particular at least 60° °, preferably at least 70 ° on a welding bevel 6 and 7 can look.

The geometric shape of the component connection section 41, in particular the component radius surfaces 47 and 49, and the element connection section 21, in particular the welding bevels 34 and 35, is selected such that the welding notches 6 and 7 are designed for introducing an HV weld seam . For example, the welding notches 6 and 7 between the respective welding bevel 34 and 35 and the respective radius surface 47 and 49 enclose an angle of more than 50° and less than 100°.

A minimum distance between the first welding notch 6 and the second welding notch 7 can be defined as profile welding distance 18 . This is at least 20 mm, in particular at least 40 mm, preferably at least 50 mm and/or at least 70%, in particular at least 80%, preferably at least 85% of an element width 39 of the profile element 20 and/or a component width 59 of the profile component 40 .

7 shows an alternative embodiment of a support structure 2 similar to the support structure 2 according to the embodiment of FIG 3 until 6 . In particular, a large number of features are designed to be the same or identical, with the embodiments differing significantly in a modified component connection section 41 . The component connection portion 41 of the profile component 40 of 7 has an interrupted area 57, so that the first component radius surface 47 and the second component radius surface 49--through the interrupted area 57--are arranged separately from one another. Since the component radius surfaces 47 and 49 do not merge into one another and the interrupted area 57 is provided instead, the overall weight of the supporting structure 2 can be reduced and/or accessibility to an interior of the profile component 40 can be made possible.

8th shows a further embodiment of a support structure 2 having a profile element 20, a profile component 40 and an additional profile element 60. The profile component 40 connects the profile element 20 and the additional profile element 60 to one another. For this purpose, the profile member 40 has a first member connecting portion 41 for forming a first and second weld notch 6 and 7 and for making a connection with the member connecting portion 21 and a further member connecting portion 56 for forming a third weld notch 16 and a fourth welding notch 17 and for establishing a connection with an additional element connection section 61 of the additional profile element 60.

With regard to the basic functional principle, the supporting structure 2 is designed according to 8th similar to the execution 3 until 6 formed, the profile component 40 having a web 83 is formed as a tube-shaped profile with internal ribbing. As an alternative to this—not shown—the profile component 40 can also be designed in an oval shape.

The profile component 40 now has a third component radius surface 52 with a third component radius 53 and a fourth component radius surface 54 with a fourth component radius 55 on the further component connection section 56 . These serve to establish a statically at least determined contacting of the further component connection section 56 with an additional element connection section 61 of the additional profile element 60 .

The additional profile element 60 can be substantially similar to the profile element 20 with an additional element connection section 61 and an additional element body 68 and an additional element width 79, with an additional element profile direction, an additional element profile axis, an additional element profile plane, an additional element Vertical axis 65 and an additional element transverse direction 66 be designed. The additional profile element 60 has in the area of the additional element connection section 61 a first additional element stop 72, a first additional element welding bevel 74 and in particular a first additional element gas pocket 76 lying in between. Furthermore, a second additional element stop 73, a second additional welding bevel 75 and in particular a second additional gas pocket 77 lying in between are provided. In particular, a first additional element radius surface 67 is provided on the first additional element stop 72, and a second element radius surface 69 is provided on the second additional element stop 73 for contacting the third component radius surface 52 and the fourth component radius surface 54 of the profile component 40. The first and second additional element radius surfaces 67 and 69 are curved with a respective first and second additional element radius 70 around an additional element center point 71 of the additional profile element 60 .

Since four weld notches 6, 7, 16, 17 are now formed, profile element 20, profile component 40 and additional profile element 60 are materially connected to one another by means of a first weld seam 8, a second weld seam 9, a third weld seam 12 and a fourth weld seam 13.

In order to maintain the necessary welding distance, the profile component 40 is designed in such a way that the first component radius surface 47 and the third component radius surface 52, and the second component radius surface 59 and the fourth component radius surface 54 are spaced apart in such a way that the first Welding notch 6 and the third welding notch 16 and the second welding notch 7 and the fourth welding notch 17--regardless of the selected relative positions--are spaced apart by a supporting structure welding distance 19 from one another. The support structure welding distance 19 is at least 20 mm, in particular at least 40 mm, preferably at least 50 mm and/or at least 70%, in particular at least 80%, preferably at least 85% of the component width 59 of the profile component 40.

Although specific embodiments have been illustrated and described herein, it is within the scope of the present invention to appropriately modify the shown embodiments without departing from the scope of the present invention; For example, a support structure can be formed by a large number of profile elements 20 and additional profile elements 60, each connected by round or oval-shaped profile components 40.
