Description

Side member for the transition region of a car body side wall to the car body roof of a rail car body

The invention relates to a side member for the transition region of a

Car body side wall to the car body roof of a rail car body to which various car body roof sections can be easily attached, a side wall for a rail car body, a car body and a rail vehicle, comprising such a side wall or such a longitudinal beam, and also a method for producing a

Railcar body with different roof sections.

Rail car bodies can have both arched roof areas, too

have designated as a contour roof areas, as well as flat roof areas or less steeply rising roof areas. The roof level in the flat roof areas is lowered in relation to the roof level in the arched roof areas. On the flat roof sections are, for example, air conditioners, pantographs

Energy storage or drive devices arranged. By arranging such devices on flat roof areas is avoided that these devices protrude above the height level of the domed roof sections, or it is at least achieved that they protrude less far.

The flat roof areas in car bodies were previously, for example, with a

Roof trough realized. Such a roof pan has a horizontal or a substantially horizontal floor, which forms the roof surface, and rising

Side walls. A roof trough can be connected to a contour roof.

For example, a rectangular opening is created in a contour roof, in which a roof pan is welded.

EP 1839989 A2 describes a car body for rail vehicles with a lowered flat roof area. For insertion of such a flat roof area, a lateral structural body, which is arranged at the upper end of the side wall, cut off to a point of attachment for a trough-shaped lowered

To create flat roof area. The disadvantage of such a solution is that a part of the lateral construction body has to be cut off in order to make accessible a point of attachment for attaching a flat roof area.

CONFIRMATION COPY An object of the present invention is to facilitate the attachment of different roof areas with a different height, and in particular to facilitate the attachment of flat roof areas.

As a solution, the invention proposes a side member and a side wall, as indicated in the appended claims. Particularly advantageous embodiments of a longitudinal member and a side wall are specified in the subclaims. Also stated is a rail vehicle body with different heights roof areas and a method for producing such a rail vehicle car body.

The invention relates to a side member for a rail vehicle body, comprising:

a in the installation position vertically upwards or obliquely upwardly facing first attachment point for a first roof section,

a second attachment point pointing in the installation position in the direction of the carriage body inner side for a second roof portion, which is arranged below the first attachment point, a third attachment point for a carriage body side wall pointing downwardly in installation position or obliquely downward;

wherein the longitudinal carrier is integrally formed.

As used in this description, the "car body inside" corresponds to the car body inside a side wall or an imaginary extension of a side wall upwards.The term "toward the car body inside" does not necessarily mean that a point of attachment or a projection described below in the interior of the car body shows This is at least not the case when a roof section is attached to the attachment point or the projection. The term "towards the car body inside" does not necessarily mean "towards

Car Interior "The following examples serve as illustration: Is the

Longitudinal member disposed above a right side wall in the direction of travel, so the term "towards the car body inside" means that the second attachment point in

Direction of travel points to the left. If the longitudinal member is arranged above a left side wall in the direction of travel, then the term "towards the vehicle body inside" means that the second attachment point points in the direction of travel to the right. The same applies to a first attachment point or a (hereinafter described) first or second projection, provided that they are defined in their orientation with respect to a Wagenkasteninnenseite. Another explanation of the car body inside and

Car body exterior is given in the figure description.

The longitudinal member is a supporting element of the car body and extends in

Car longitudinal direction between side wall and roof. In other words, it is arranged in the transition region from the side wall to the roof. An inventive carrier is also referred to as the upper belt. The side rail can be part of a

Car body be integral or be intended for a car body in Integralbauweise.

According to a basic idea of the invention, the longitudinal member has an attachment point at which a first roof section can be attached and attached, for example an upwardly curved roof section, and a further attachment point, to which a second roof section, for example, a flat roof section can be attached and attached , As a result, depending on the needs of the side rail different roof sections are mounted and within the same

Rail car may e.g. alternately different roof sections are created. By the "first roof section" and the "second roof section" are meant various types of roof, which can be arranged consecutively in the longitudinal direction of the carriage on the longitudinal member. The difference between the mentioned first roof section and the mentioned second roof section is in particular that the first roof section protrudes upward beyond the second roof section. This means in particular that the first roof section is higher at its highest point than the second roof section. Another difference is that preferably only the second roof section for attachment of

Devices, such as air conditioners, energy storage devices, drive devices or Dachstromabnehmern is provided, but not the first roof section. The cross-sectional shape of a roof or a roof section may vary in its course in the carriage longitudinal direction.

When the side member is installed in the car body, it extends in

Longitudinal direction of the car body, and preferably over the entire length of Car body. The aforementioned attachment points for the side wall and the first and second roof sections extend over the entire length of the carrier, preferably over the entire length of the car body. In particular, the

Cross-sectional shape of the longitudinal member over the entire length substantially equal. The surfaces that define the attachment points, therefore, in particular over the entire length of the same width and possibly the same cross-sectional profile.

The longitudinal member according to the invention is made in one piece, for example as

Extruded profile, and extends in the car body longitudinal direction preferably from the front end of the car body to the rear end of the car body. Particularly preferably, the side member is an extruded press profile made of metal, particularly preferably made of aluminum or an aluminum alloy. Particularly preferably, the longitudinal member is an extruded profile with a hollow chamber structure, in particular made of aluminum, wherein the chambers may be separated by walls extending in the longitudinal direction.

The advantage of the longitudinal beam according to the invention is that no mechanical machining has to be carried out on it for the attachment of different roof sections. Over its entire length, preferably the entire length of the carriage, the side member may be the same design and remain the same design, regardless of whether a first or a second roof section is attached to it or is. The available, optionally the first and second attachment point are available. To

Attaching a first roof section at the first attachment point, the unused second attachment point in this section may remain on the carrier, and after attaching a second roof section at the second attachment point, the unused first attachment point in this section may remain on the carrier.

At the downwardly or obliquely downwardly pointing third attachment point, a car body side wall can be attached to the side member and connected to the side member. An inventive longitudinal beam is arranged in particular both on the right in the direction of travel and the left in the direction of travel side wall of a car body. The longitudinal members are arranged in mirror image to each other, based on a arranged between the side walls of symmetry plane. The various roof sections in particular each extend from side member to side member and thus span the gap between the side walls. in the finished body, the side members are arranged in the transition region of the side wall to the roof of the car body.

Another advantage of the longitudinal beam according to the invention is that, in particular at its second attachment point, at least one transverse reinforcement element can be attached, for example, by way of alternative to a second roof section

Welding, which extends transversely through the car body and is preferably attached to the second attachment point of a further longitudinal member according to the invention on the other side of the car body. Such transverse stiffening elements are

for example, at locations of the car body attachable, where there is a first roof section and where the second attachment points of the side members on both sides (right and left) of the car body are not used for attaching a second roof section. A transverse stiffening element extends in this case below a first roof portion from the second attachment point of a longitudinal member on one side of the car body to the second attachment point of a side member on the other side of the car body. Preferably, this is

Transverse stiffening element made of metal, preferably aluminum. By attaching such transverse stiffening elements, the vibration behavior of the car body can be improved, especially in car bodies whose other parts in

Aluminum integral construction are made.

Preferably, the first roof section is an upwardly curved roof section. A curved roof section is also referred to in this specification as a "contour roof" or "arched roof". The term "curved" includes all conceivable radii of curvature and curved shapes, and the radius of curvature can vary and / or the cross-sectional profile can be angled. left sidewall upwards, reaches a highest point, a highest area or highest points at any point between the right and left sidewalls, and descends to the left or, in reverse viewing, right sidewall, preferably the contoured roof The second roof section may also be an upwardly curved roof section, which, however, does not project above the second roof section in particular in a mirror-symmetrical manner to a symmetry plane assumed halfway between the side walls. In a further variant, the first roof section is a roof section with a horizontally extending plateau, which is arranged higher than the side edges of the first roof section, which are connected to the first attachment point. Also the second

Roof portion may have a horizontally extending plateau, which is arranged higher than the side edges of the second roof portion, which are attached to the second attachment point, as long as the first roof portion projects beyond the second roof portion upwards.

Preferably, the second roof section is a horizontally or substantially horizontally extending roof section. Such a roof section is also referred to in this specification as a "flat roof." When viewing a body in cross-section, the flat roof between the right and left side walls is horizontal or substantially horizontal Case exactly horizontally, which is expressed by the term "essentially"

Car body side walls towards carbody center a gentle one

Tilt angle, in particular from 5 ° to the horizontal, wherein the roof of both car body side walls of up or from both

Car body side walls can be angled downwards. The angled roof areas of such a second roof section meet at the same angle of inclination in the middle of the car body each other.

Most preferably, the second roof portion is a horizontally extending

Flat roof, the shortest distance from the second approach point of a

Longitudinal member on one side of the car body (for example, the left side of the car body) to the second attachment point of a longitudinal member on the other side of the car body (for example, the right side of the car body) runs.

The connections between the roof sections and the side member and the side wall and the side member are preferably joint connections, the one

Heating the parts to be joined require. Most preferred is a weld or solder joint. In principle, however, other joining techniques are also conceivable, such as

For example, gluing or riveting. The attachment points of the longitudinal member preferably have profiled surfaces on which the provided roof sections of the car body can be attached. An example is a protruding lip. In the case of the first attachment point, the profiled surface serves for attaching a first roof section. In the case of the second attachment point, the profiled surface serves for attaching a second roof section. Roof sections may also have at their periphery a profiled surface which is complementary to a profiled surface at a point of attachment in its shape. After applying a roof section to the attachment points, a joint connection between the longitudinal member and the roof section can be produced, preferably a welded connection.

In a specific embodiment, the first attachment point has a protruding lip on which a first roof section can be laid and which can be connected by a welded connection to the first roof section. In another specific embodiment, the second attachment point has a protruding lip on which a second roof section can be laid and which can be connected by a welded connection to the second roof section.

In a specific embodiment, the invention provides a side rail comprising

a lower portion in the installation position, which has the third attachment point, a first projection in a mounting position perpendicular upward or obliquely upward with a free end having the first attachment point for the first roof section, and / or

a projecting in the installation position in the direction of the car body inside second projection which is disposed below the first projection and having a free end having the second attachment point for the second roof portion.

The following description relates to the case where there are two protrusions. However, it applies correspondingly for the cases in which only the first projection or only the second projection is present.

The projection or projections and the lower portion extend

in particular over the entire length of the carrier in the carriage longitudinal direction or at least over a longitudinal section in which different roof sections on Side members are attached. The lower portion preferably has a larger cross-sectional area in the cross-section of the side member than each of the projections. Alternatively or additionally, the width of the lower portion is preferably greater than the width of the projections. The width is determined in a direction transverse to the longitudinal direction. The lower portion is arranged in the assembled state of the car body over the side wall. The sidewall is attached to the lower portion at the third attachment point. The third attachment point is preferably located at the lower end of the lower portion. It is also possible that side wall and side members form an integral part.

The attachment point for the first roof section is at the end of the first

Projection and the attachment point for the second roof section is located at the end of the second projection. As a result, depending on requirements, a first roof section can be attached to the first projection of the longitudinal member, and a second roof section can be attached to the second projection of the longitudinal member so that different roof sections can be created on a vehicle body.

In the case of a joining connection by welding, this special longitudinal member provides the welding-technical accessibility to each of the projections, without having to separate the projection which is not required in each case. This means, for example, that the second projection on the side member can remain unused in a longitudinal section when a first roof section is welded to the first projection in the longitudinal section and vice versa.

When a second roof section is attached, thus, in particular, the first projection of the longitudinal member pointing vertically upwards or obliquely upwards remains standing. It can be used as a side shield for on the second roof section

attached devices, such as air conditioners, energy storage,

Drive devices or pantograph, serve and cover such devices or their attachment points in whole or in part. In addition to a shield against impacts from the side, such as dust and dirt, the first projection can also perform the function of a screen. If the optical

Paneling or shielding of devices on a second roof section is not required, the first projection can also be used as an attachment point for

Serve devices. In addition, the first projection in the region of a second roof section, in particular in the region of a flat roof section serve as a lateral roof boundary, which prevents a transfer of water over the roof edge. For example, the first projection in the region of a flat roof section can prevent rainwater or water from running down the side walls of the roof from the car body mounted on the flat roof. In addition to the function as a limitation, the first projection can also be used for the discharge of water itself, as explained below.

Preferably, the previously described specially designed side member is a

Extruded profile of metal, particularly preferably of aluminum. Particularly preferably, the longitudinal member is an extruded profile with a hollow chamber structure, in particular made of aluminum. Preferably, such a profile may have an outer (with respect to the interior of the car body) and an inner plate-shaped portion, which are connected by additional chamber walls. Each projection and the lower portion of the longitudinal member according to the invention can have an outer and an inner

plate-shaped area, which are interconnected by additional chamber walls. Likewise, however, the projections may also be formed from a single chamber of a hollow chamber profile. At its end, the projections are preferably closed, for example by a transverse wall.

In a special embodiment of the longitudinal member, the first projection has a drainage channel in its interior. The drainage channel serves to discharge water from a roof section, preferably from a second roof section. Preferably, the drainage channel extends in

Car longitudinal direction. A drainage channel extending in the vehicle longitudinal direction can extend over the entire length of the first projection or only along a part of the projection. The first projection has at least one inflow opening and at least one outflow opening, between which the drainage channel extends. The inflow opening (s) is accessible from the second roof section, for example by being arranged on the side of the projection which faces the second roof section. The drain opening may be arranged at various locations, for example at a longitudinal end of the projection, which at the front end in the direction of travel or at the rear end of a car body is arranged. At the outlet opening, a nozzle or a drain pipe may be attached.

The embodiment just described is particularly advantageous with a

Can be combined embodiment in which the first projection is formed from one or more chambers of a hollow chamber profile. Then, such a chamber serves as a drainage channel.

The dimensioning of the projections can basically be chosen freely.

The length of a projection is determined by the length of the longitudinal member

Cart longitudinal direction defined. The depth of a projection corresponds to its extension from a base of the longitudinal member, in particular from the lower portion, to its free-standing end.

In a cross-sectional view (transverse to the longitudinal direction of the car body) viewed through the side member, the ratio of the width to the depth of the projections can be independent of one another, greater than 1, or smaller than 1. The width of a projection may vary in the depth direction. For example, at least one of the projections may taper towards its free end.

At their ends, the projections preferably have a profiled surface on which the components of the car body intended for this purpose can be attached. In the case of the first projection, the profiled surface serves for applying a first roof section. In the case of the second projection, the profiled surface serves for applying a second roof section. The roof sections may have at their edge a profiled surface which is complementary to a profiled surface at the end of an associated projection in its shape. After applying a

Roof element can be made a joint connection between the end of the respective projection and the roof element, preferably a

Welded joint.

In a special embodiment, the first projection has at its free end a protruding lip on which a first roof section can be laid and which are connected by a welded connection to the first roof section can. In this embodiment, preferably also has the first roof portion at its end, which is connected to the free end of the first projection, a protruding lip which is placed when placing the roof section on the lip of the projection on the first projection, and in turn over a

Welded connection can be added to the first projection. To create a planar connection point, the first projection at the point of contact with the overlapping lip of the first roof section can have a depression into which the lip of the first roof section is inserted and fits.

In another specific embodiment, the second projection has at its free end a protruding lip on which a second roof section can be laid and which can be connected by a welded connection with the second roof section. In this embodiment, preferably, the second

Roof section at its end, which is connected to the free end of the second projection, a protruding lip which is placed on the lip of the projection on the second projection when placing the roof section, and which in turn are joined via a welded connection to the second projection can. To create a flat joint, the second projection on the

Contact point to the overlying lip of the second roof section have a recess into which fits the lip of the second roof section.

The lower portion of the side member may, for example, in the third attachment point, opposite to each other of the lower portion abknickende lips abut two of the end of a side wall member lips and wherein at the transition points of the abutting lips a welded joint between the side wall and the Longitudinal beams can be executed.

The first protrusion of the side member may extend vertically upwards or obliquely upward. "Inclined upwards" means that the first protrusion increases in cross section (transverse to the longitudinal direction of the car body) toward the car inner side The projection may also be straight on one side (inside or outside) and curved on the other side (inside or outside) Connect contour roof. Particularly preferably, the first projection extends obliquely upwards.

A preferred angle of the rectilinear extent of the first projection to an imaginary horizontal line is in particular 20 ° to 70 °. At an obliquely upward projection advantageously a first roof section is attached, which extends at its lateral ends obliquely downwards. In particular, the angle of the obliquely still upwardly extending first projection and the angle of the course of the roof section are identical at its end to the horizontal.

The second projection points to the car body inside. It extends in cross section (transverse to the longitudinal direction of the car body) preferably horizontally or substantially horizontally. The second projection may be straight or curved to its free end, with the straight shape being preferred. Substantially horizontal with respect to the second projection means that it may extend up to an imaginary horizontal line up to 10 ° upwards or downwards by up to 10 °.

In a special embodiment, the second projection projects beyond the first projection in the horizontal direction in the direction of the vehicle body inside. In other words, this means that seen from above on the longitudinal member, the free end of the second projection is visible and is not covered by the first projection. In this embodiment, a particularly good welding accessibility of the second projection is given from above, because the weld is not covered by the first projection.

In a special variant, viewed in cross section, the depth of the first

Projection and the depth of the second projection so dimensioned that an imaginary connecting line from the free end of the first projection to the free end of the second projection with the horizontal forms an angle of 40 ° to 50 °. The free end is defined in the case of a projecting lip by the free end. Otherwise, at the free end, e.g. an outer wall of a hollow chamber profile.

The advantage of this embodiment is that the free end of the first

Projection can be used as a guide for a welding torch when a second roof section is welded to the second projection. The welding torch, in particular its combustion tube, is thereby supported or ajar against the free end of the first projection and the burner opening of the welding torch aligned with the free end of the second projection, to which the second to be attached

Roof section abuts. A so aligned welding torch can in

Carriage longitudinal direction are guided along the free end of the first projection and a weld between the free end of the second projection and the adjacent flat roof part can be generated. In this process remains the

Welding torch optimally aligned, in particular optimally to create a

Lap seam between the second projection and the second roof section.

In yet another embodiment, the second projection of the longitudinal member has on its underside a fastening means for fastening an inner lining or other components or assemblies. In this embodiment, the second projection of the longitudinal member has a dual function, namely the function as

Connection point for a second roof section and the function of a

Attachment point, e.g. for interior trim, for example interior ceilings, or other components, e.g. Cable ducts and elements of air conditioners.

A preferred example of a fastening means is a fastening rail, in particular a C-profile rail. The attachment means may be on the second

Projection fastener fasteners, or the fastening means may be made as an integral part of the second projection, for example as a region of the extruded profile.

Previously described longitudinal members may be connected to one or more first and / or second roof sections to form a component which is used as a mounting unit or preassembled module in the construction of vehicle bodies. Thus, the invention also relates to a component for a rail vehicle body, comprising or consisting of previously described longitudinal members and one or more attached to the side rails first and / or second roof sections.

In a further aspect, the invention relates to a side wall for a

Rail car body, which at its upper end

preassembled module is used in the construction of car bodies. Thus, the invention also relates to a component for a rail vehicle body, comprising or consisting of previously described side walls and one or more attached to the side walls of the first and / or second roof sections.

In addition, the invention relates to a car body for a rail vehicle having a previously described longitudinal beam or a previously described side wall. In particular, the car body has at least a first roof section and at least one second roof section, wherein the first roof section protrudes in the longitudinal direction over the second roof section when viewing the car body. For this purpose, reference is made to the above disclosure of roof sections. Particularly preferred is a car body, in which the first roof section is a curved roof section and the second roof section is a horizontal or substantially horizontal roof section.

In yet another aspect, the invention relates to a rail vehicle having a carbody as previously described. Preferred rail vehicles are metros, commuter trains, long-distance trains, high-speed trains and

Trams. Particularly preferred are rail vehicles in Integralbauweise.

This is merely a graphical representation and does not mean that the side member 10 may be made of a different material must be as a contour roof 4 or a side wall 2. Preferably, all these parts are made of aluminum. The longitudinal member 10, formed from a hollow chamber profile, has an obliquely upwardly facing first projection 1 1 with a free end 12. The free end 12 forms the first Ansatzstetle for a first roof section. At the free end 12, the curved car body roof 4 is welded in this embodiment. Details of the welded connection are described below in FIG. 4. In addition, the longitudinal member 10 has a second projection 13 with a free end 14. The free end 14 forms the second attachment point for a second roof section. The second projection 13 points horizontally in the direction of the car body inside and is arranged below the first projection 11. The first projection 1 is formed from a single chamber of a hollow chamber profile and it is tapered in the direction of its free end 12. The second projection 13 is formed from two chambers of a hollow chamber profile and tapers in the direction of its free end 4. The free end 14 of the second projection 13 is exposed, since no flat roof is mounted in this area of the car body. The car body outside is denoted by the letter A and the car body inside by the letter B. The dashed line, which is drawn in extension of the side wall 2 forms, together with the car body side wall, the boundary line between the car body inside B and car body outside A according to the definition of this invention. The dashed line corresponds to an imaginary extension of the side wall 2 upwards. A corresponding dashed line is also shown in FIG. 7. It can be seen in FIG. 3 that the second projection 13 protrudes beyond the first projection 11 in the horizontal direction and that it protrudes beyond the first projection in the direction of the vehicle body inside B. In the bottom of the second

Projection 13 is a fastening means 15 is provided in the form of a downwardly open C-rail. The C-rail is an integral part of the extruded profile. A lower portion 16 of the longitudinal member 10 is connected at its lower end 17, which here is the third attachment point, with the right side wall 2.

The lower portion 16 has at the lower end two mutually inwardly kinking lips 18, against which two of the end of the side wall 2 protruding lips 19. The lips 18 and 9 are connected to each other by a welded joint, whereby the connection of the side wall 2 to the side member 10 and the lower portion 16 is made. In the embodiment shown, the side wall 2 also has a fastening means 20 in the form of a C-rail. 4 shows an enlarged detail of FIG. 3, in which the attachment point between the first projection 11 of the longitudinal member 10 and the contour roof 4 is shown. From Fig. 4 it can be seen that the first projection 11 of the longitudinal member 10 at its free end 12 has a protruding lip 30, on which the

Contour roof 4 is placed. The contour roof 4 has at its end 31 in turn a protruding lip 32 which lays on the car body outside on the first projection 1 1. Between the end 31 of the contour roof 4 and the end 12 of the longitudinal member 10, a gap is formed as compensation for manufacturing tolerances. The first projection 1 1 has at the contact point to the lip 32 a recess 33 into which the lip 32 is fitted to create a flush transition from contour roof 4 to longitudinal member 10. At the end 34 of the lip 32 of the contour roof and at the end 35 of the lip 30 of the longitudinal member 10 overlap welds are performed to add the contour roof 4 to the free end 12 of the first projection 11 of the longitudinal member 10. The provision of such a welded connection is shown in FIGS. 5a and 5b. In Fig. 5a is a detail of the extension of the longitudinal member 10 in the carbody longitudinal direction shown, in addition to a section through the side member 10 and a side wall 2 in the transverse direction. Fig. 5b shows only a section in the transverse direction. In Fig. 5a it can be seen that the side rail 10 is in one piece, i. it extends seamlessly from one end of the car body, which can be seen in Fig. 5a on the right edge of the picture, to the other end of the car body, which is in the view of Fig. 5a on the left side, in the figure itself but no more is shown. The longitudinal member 10 is in

Transition region arranged from the side wall 2 to the roof 4 and is also referred to as top chord. FIGS. 5a and 5b show the welding-technical accessibility of the first projection 11 for creating a welded connection to the contoured roof 4. The welding torch 50 can be applied to create a weld from the inside of the car body. The welding accessibility to the first projection 1 1 is given without the second projection 13 must be separated. Optionally, the welding torch 50 may even be ajar against the second projection 13 and guided along the second projection 13 in the body longitudinal direction (in the direction of the viewer in FIG. 5 b).

Fig. 6 shows a section through a car body 1 along the line II-II shown in Fig. 1 b. It is a section through an area of the

Car body 1, in which a flat roof 3 is mounted. The inventive

Longitudinal member 10 connects the car body side walls 2, 8 with the flat roof. 3 Otherwise, reference may be made to the explanation of FIG. 2 for further explanation of the figure.

Fig. 7 shows the detail Y of FIG. 6 in magnification. A side wall 2 is attached to the third end 17, which here is the third attachment point of the lower portion 16 and a flat roof 3 is attached to the free end 14 of the second projection 13. The free end 12 of the first projection 11 is exposed and the projection 11 also remains in the flat roof area on the car body. The projection 11 extends beyond the level of the flat roof 3 and can serve as a lateral shield for devices mounted on the flat roof (not shown here), such as e.g. Air conditioning. Depending on the dimensions of such a device and the projection 1 1, the projection of the device wholly or partially to the car body outside A at the side

Cover observation (in the picture from left to right). To explain further features of FIG. 7, reference is made to FIG. 3.

FIG. 8 shows an enlarged detail of FIG. 7, in which the

Joint of flat roof 3 to the second projection 13 of the longitudinal member 10 is shown in detail. The second projection 13 has at its end 14 a protruding lip 40 on which the contour roof 3 is placed. The contour roof 3 has at its end 41 a lip 42 which rests on the second projection 13. To create a flat joint from flat roof 3 to second projection 13, the second projection 13 has a recess 43 into which the lip 42 of the flat roof 3 fits. At the end 44 of the lip 42 and at the end 45 of the lip 40 are in the carriage longitudinal direction (in this view, in the direction of the viewer)

Overlap welds created to add the flat roof 3 to the free end 14 of the projection 13.

FIG. 9 shows how the free-standing first projection 11 can serve as a guide for a welding torch 50. The welding torch 50 is guided in the carriage longitudinal direction (viewing direction of the viewer) along the projection 11 to a

Weld connection between the flat roof 3 and the second projection 13 to create. The burner tube 51 of the welding torch 50 is at the edge of

protruding lip 30 ajar at the free end 12 of the first projection 1 1 and the opening 52 of the burner tube 51 aligned with the free end 14 of the second projection 13. By so doing the welding torch at the end of the lip 30 at the free At the end 12 of the first projection 11 in the longitudinal direction of the carriage, the welding torch remains at the optimum angle, which is approximately 45 ° here, in order to create an overlap weld between the flat roof 3 and the second projection 13. In the embodiment shown here, the burner nozzle 51 abuts the end of the lip 30. In the embodiment shown here, the length of the first

Projection 11, including lip 30, and the length of the second projection 13 so dimensioned that an imaginary line connecting the end of the lip 30 to the free end 14 of the second projection 13 with the horizontal (here, for example, the roof line of the flat roof 3) at an angle of forms about 45 °. The outermost point of the projection 11 is the end 35 of the lip 30. If no lip 30 is provided at the free end 12 of the first projection 11, forms the end 12, here in the form of a final profile web, even the outermost point and the support point for the Burner nozzle 51. In this case, the first projection 11 would ideally be dimensioned such that an imaginary connecting line from the free end 12 to the free end 14 forms an angle of 45 ° with the horizontal. Fig. 9 also shows the very good

Welding technical accessibility of the junction of flat roof 3 to the second projection 13 of the longitudinal member, because the second projection 13 protrudes beyond the first projection 11 in the horizontal direction (in this illustration, horizontally to the left).

Fig. 10 shows the drainage of a flat roof area 3. The first projection 11 of a longitudinal member 10 has in its interior a drainage channel. The first projection 1 is formed from a single chamber of a hollow chamber profile, such as e.g. shown in Fig. 3 and 4, and this hollow chamber serves as a drainage channel. The drainage channel extends in the carriage longitudinal direction and only along a part of the projection 1 1. The drainage channel extends from an inlet opening 60 to a drain opening 61. The inlet opening 60 is accessible from a flat roof section 3 from. In the area of the inflow opening, the walls of the profile hollow chamber of the first projection 11 are partially removed, whereby a drainage niche has been created. Regions of the hollow profile chamber of the first projection 11, in which no

Drainage channel is provided, are closed with a plate 64. The

Outlet opening 61 is disposed in the lower portion of the hollow profile chamber of the first projection 11 and it is located at the bottom of the longitudinal end 63 of the projection 11 and thus at the end of the car body 1. The profile chamber of the first projection is closed at the longitudinal end 63 by a plate 65 so effluent water is discharged exclusively through the downwardly facing drain opening 61. In principle, it would also be possible to leave the profile chamber of the first projection laterally open and drain water through this opening. At the drain opening 61, a pipe socket 62 is welded to the first projection 11. At the pipe socket 62, a further piping can be connected to specifically discharge effluent water to certain positions of the undercarriage (not shown) of the car body 1, for example, to the center of the track bed. The direction of flow of the running of the flat roof section 3 water is indicated by arrows. As indicated by the arrows, water is directed from the flat roof to the end of the car.
