FOR CARRYING AND CROSSING

The invention relates to a switchable chassis arrangement with a bend rigid chassis frame for carrying and tilting the body of high-speed rail vehicles.

The prior art WO 87/05 873 discloses, as the state of the art, a rail vehicle consisting of two portal-type driven individual wheel units or two non-driven individual wheel units with steered wheels interconnected by a carrier and supply unit, and Portable trailer is a self-supporting and walkable unit for picking up a container-like passenger or payload.

Such portal landing gear units allow for the creation of an extremely low floor throughout the vehicle's length, but the assemblies in the support and supply portions generate a relatively high center of gravity and are therefore unsuitable for a tilting device. The steered wheels are very well suited to small bend radii, such as those found in trams, to significantly reduce steering forces at bends and thereby reduce wheel rail wear, but this is not a problem for high-speed rail vehicles, one-sided wheel running and tilting torque. the so-called keep it on a small base when loose wheel bearings.

WO 91/02673 discloses two steerable, single-axle, single-axle chassis solutions, where the axially spaced and rigid and torsionally flexible coupling members for driving and braking forces, which are intended to accommodate a low-floor body, are not releasably coupled to one another. .

83267-2131 WE / Tz • · ·· ·

The combination of low floor design and tilt technique cannot be achieved with these solutions.

Therefore, the high-speed rail vehicle of U.S. Pat. No. 2,893,326 has a unique suspension and a stepped suspension on which a low-floor, low-body car body rests.

This solution is for solid, inseparable kits, where one side of the body of the car has a bike with unique undercarriage and the other side of the undercarriage rests on the adjacent body of the front, so that each bicycle automatically adjusts to a curve when cornering.

In order to be able to follow deviation wishes, detachable individual vehicles are more advantageous at the plant.

Ivory-adjustable bicycle custom-made landing gear, which are arranged in pairs under a car body and can be controlled in a controlled curve, are known from CH-PS 329 987.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a switchable chassis arrangement with a bend rigid chassis frame for carrying and tilting the body of a vehicle running on a rail, in particular for a high speed rail vehicle.

Thus, the invention relates to a switchable chassis arrangement with a bending rigid chassis frame for carrying and leaning the body of high-speed rail vehicles.

It is an object of the invention that a walkable unit has at least two cycles with individual undercarriages, paired in a common undercarriage frame, which is directly supported by the individual undercarriage of each bicycle and has means for carrying and tilting the car body.

To this end, two steered bicycles have individual suspension with direct suspension, which makes the bending stiff, the two bikes unique hair • ·· ·

- Rests on a chassis frame linking 3 toms, serving as a support and support portion for a container-like pick-up of a low-floor wagon, with a tilt device between the two.

The design of the present invention provides a low-floor rail vehicle at high speed, whereby the chassis frame, together with two individual bikes, forms an autonomous unit. These can run into curves at high speeds without passengers being subjected to increased thrust or the wheel-rail pair being subjected to excessive friction or wear.

Until now, this problem could not be solved with prior art devices.

DETAILED DESCRIPTION OF THE INVENTION The invention will now be described in detail with reference to the drawings, in which, in addition to the structure, their effects and operation are understood. In the drawings it is

Fig. 3 is a schematic view of the front view of Figs. 1 and 2, a

Figures 5 and 6 are perspective views of a preferred embodiment of a unique suspension for a bicycle.

1-3. Figures 2 to 5 illustrate two two-axle vehicles running on 1,1 'rails with individual bogies 2, 3, 2', 3 'having a common frame 4, 4' which in turn each has a direct suspension 5, 5 '; ', 3' bikes rely on a unique suspension. The chassis frames 4, 4 'are interconnected by releasable coupling systems 6, 6' having a control device 7, 7 'for adjusting the bending radius of the individual chassis bikes 2, 3, 2' 3 '. On the 4, 4 'chassis frame, one low-floor 8, 8' co ·· ···· ·

Preferably, the sanding box 4 is supported by an active leaning device 9, 9 'and provided with an easily removable passenger passage 10, 10' which can be carried and guided by the coupling systems 6, 6 'or even be self-supporting.

The two individual bicycle bikes 2, 3, 2 ', 3' are interconnected by means of a wheelbase frame 4, 4 'which fixes an axle distance and receives the driving and braking forces. Thereby, a self-propelled unit 11, 11 'is formed which can be interconnected by means of a coupling system 6, 6' and has the advantage, for example, of being transported independently of a conventional bogie when suspended on a train without having to be loaded onto a transport trolley. Each of the walkable units 11, 11 'serves for the container-like pick-up of the body 8, 8'. This may be optionally self-supporting or non-self-supporting and at least at two locations supported on the chassis frame 4, 4 '. The chassis frame 4, 4 'may be identical to the chassis frame of a carriage 8, 8'.

For this purpose, according to Fig. 4, a chassis frame 4, 4 'is longitudinally bending stiff, and diagonally transverse twisting is soft so that each tensile and compressive force can be absorbed longitudinally and transversely. Provides support and supply units for a 1,1 'rail vehicle and provides other communication devices such as power and electronic equipment, propulsion, air conditioning and additional volume for the 5, 5' direct suspension when using air springs.

The chassis frame 4, 4 'consists essentially of a long through-going base plate 18, which in the region of the wheels 13, 13', namely the wheels of the individual chassis 2, 3, 2 ', 3' , 5 'for direct suspension. The side supports 14, 14 'are provided with openings 15, 15' for the wheels 13, 13 'of the individual axles 2, 3, 2', 3 '. Alternatively, closed cupboards may be considered. Thus, a transverse U or V-shaped cross-section 16, 16 'is formed in the region of the side supports 14, 14', which serves as a trough-shaped passage for the low-floor floor 12, 12 'of the body 8, 8'. In addition, the side supports 14, 14 'for the direct suspension 5, 5' extend into the space of the seat cushions 34, 34 'of the body 8, 8'. The chassis frame 4, 4 'is adapted to receive the coupling system 6, 6' on each end face 19, 19 '.

Between the running gear frame 4, 4 'and the car body 8, 8' there is provided an active tilting device 9, 9 'which is actuated by an electrically driven adjusting member 20 and preferably is formed as a roller track, while the running gear 4, 4' frame accommodates the roller track segments 21, 21 'and the car body 8, 8', rollers 22, 22 'or vice versa. It is also possible to use a rope path principle in which the rollers 22, 22 'move on an approximately semicircular rope path, or an incline mechanism with pendulum support or pendulum suspension.

Alternatively, the active crossover device can be hydraulically or pneumatically implemented.

Due to the arrangement of the individual chassis 2, 3, 2 ', 3' of the two bicycles, the chassis frames 4, 4 'to be interconnected are possible to cross between the chassis frames 4, 4' and the body 8, 8 'with only one 9, 9' also create 1, T per vehicle. In addition, the electrically driven adjusting member 20 may be arranged at any position on the chassis frame 4, 4 ', but preferably in the center of a vehicle 1.1' running on a rail or adjacent to an individual chassis 2, 3, 2 ', 3'.

In a simple exemplary embodiment, it is possible to support the container-like body 8, 8 'without the cross-member 9, 9' with substantially damping rubber, metal elements or hydraulic bearings on the chassis frame 4, 4 '.

This rational design provides a quick solution for supplying walkable units 11, 11 'with container-like bodies 8, 8' in special cases.

In a very simple way, cheap car bodies 8, 8 'can be realized, which, if they are no longer up to date, can be rapidly replaced with a new design or appearance or even used for other purposes.

The chassis frames 4, 4 'are interconnected by a separable coupling system 6, 6' according to Fig. 2, wherein the coupling length is zero. To this end, each vehicle frame 4, 4 'is provided with a coupling half 23, 23', which may for example be in the form of a releasable pole switch or an automatic switch. In parallel, there is a transversely rigid and longitudinally displaceable and self-releasing joint 24, 24 '. Additionally, any Intercar coupling, such as suspension, damping, can be included to accommodate each axle within the frame of two adjacent 1,1 'rails 4, 4'.

As a result, the individual bogies of the bicycle 2, 3, 2 ', 3' are forced over the entire transverse path which is created by the direct suspension 5,5 'according to the invention. By means of 5, 5 'direct suspension, the springs and damping around and in each axle, and as a result of twisting motion, cornering, are mounted between the individual bogies of the 2, 3, 2', 3 'bikes and the 4,4' except that no significant relative displacement is made between the chassis frames 4, 4 'and the chassis 8, 8'.

It should also be borne in mind that the axles 4, 4 'and the body 8, 8' may have multiple axle springs, thereby allowing additional relative displacements. Further, it is possible to connect the chassis frame 4, 4 'to the coupling system 6, 6', where the switch length is zero.

The passenger passage 10, 10 'leaning on the coupling system 6, 6' and connecting the two car bodies 8, 8 ', having regard to the fact that the coupling system 6, 6' is not forced by a horizontal transverse displacement, with the width of the body 8, 8 ', which has a positive effect on passenger traffic and the clarity of the assembly.

Each of the clutches 23, 23 'engages a bicycle control 25, 25', the bicycle 2, 3, 2 ', 3' to adjust the radial position of the individual running gear when running on a curve. In addition, the coupling halves 23, 23 'are mirror-shaped and are actuated by a transverse lever 26, 26' which is pivotally mounted on the chassis frame 4, 4 'by means of the swivel arms 2, 3, 2' , 3 'bicycle acts on the unique suspension suspension C-shaped 29, 29'. The coupling points of the regulating device 7, 7 'are formed by rubber-resilient bearings to allow movement of the universal joint.

If the individual bogies of the bicycle 2, 3, 2 ', 3' are guided through the coupling system 6, 6 'according to the invention, the control device 7, 7' is disengaged longitudinally by the arrangement of the cross arms 26, 26 '.

5 and 6, each of the bikes 2, 3, 2 ', 3' provides individual suspension 5, 5 'for direct suspension of the frame 4, 4', 44, 44 ', which is known directly from air springs 30, 30'. They consist of a serial or parallel arrangement and a delayed-acting auxiliary spring 31, 31 '. The single stage suspension of the chassis frame 4, 4 ', 44, 44' is disposed above each axle bearing space 32, 32 ', which is provided at the end of each axle pair of a bicycle 33, 33'.

The 5,5 'direct suspension is configured so that all vertical movement but horizontal cross movement as well as pivoting between 2, 3, 2', 3 'individual bogies of the bicycle and between the 4, 4' chassis frame when cornered may be taken over. Thereby, it is advantageous that the two later types of movement can no longer exist between the chassis frame 4, 4 'and the chassis 8, 8', and between two vehicles running on two-axle 1,1 'rails.

Instead of two axle bearings 32, 32 ', a bicycle 33, 33' is interconnected with a C-shaped shaft 29, 29 ', which is preferably angularly rigid. Thus, the angular rigidity of the shaft bearing can be omitted, and therefore any single or double row pendants, roller bearings, etc. can be used.

The stop bracket 29, 29 'is supported at each outer end by a stabilizer bar 35, 35' vertically on the chassis frame 4, 4 ', 44, 44' and has longitudinally-adjustable longitudinal arms 28, 28 '. The lengthers are transmitted from the bicycle 33, 33 'through the impact bar 29, 29' and through the pivoting arm 28, 28 'and redirected by the angular arms 27, 27' and conveyed through the pivot arms 26, 26 'to the coupling system 6, 6'. . Since the force from the other side is equally high but in the opposite direction, no control movements occur and the control device 7, 7 'is not actuated. Thus, the switching system 6, 6 'of the present invention not only has the control devices 7, 7' provided with a

2, 3, 2 ', 3 bikes for individual chassis, but at the same time serve to extend them. Thus, the connecting points of the stabilizer rods 35, 35 'and the connecting points of the pivot arms 28, 28' and the transverse arms 26, 26 'are implemented as rubber-resilient bearings, which allow for cardan-like movement.

5 and 6, a self-supporting car body 8, 8 'is disposed within the chassis frame 44, 44', which is located on both chassis 2,

It relies on a unique chassis for 3, 2 ', 3' bikes. The landing gear frame 44, 44 'comprises an outer support 14, 14' for receiving the wheel 13, 13 ', which leans directly on the suspension 5, 5'. The two outer supports 14, 14 'are connected to each other by cross members 37, 37' arranged adjacent the shaft 36 and inclined to its height. Thus, in the region of the low-floor floor 12, 12 'they are guided in the form of a turtle 17.

The car body 8, 8 'is supported on each of the landing gear frames 44, 44' by means of a tilting device 9, 9 ', preferably with rollers 22, 22' having circular track segments 21, 21 'arranged on the landing gear frame 44, 44'. while an electrically actuated actuator 20 is disposed between the chassis frame 44, 44 'and the car body 8, 8'. This embodiment is considerably lighter and cheaper than the chassis frame 4, 4 'shown in Figure 4.

In a further embodiment, a non-depicted, self-acting cross-spring device is provided between the C-shaped stop brackets 29, 29 'and the landing gear frame 4, 4', 44, 44 '. Further additional spring elements may be provided between the 4, 4 ', 44, 44' landing gear frame and the individual bike suspension 2, 3, 2 ', 3', such as active frame and vertical dampers, as well as active, passive or switchable dampers.

Similarly, the stop bracket 29, 29 'serves to hold the disc brake assemblies 38, 38' which, with respect to the low floor 12, 12 'passing through, are preferably designed as wheel brakes.

In a switchable suspension arrangement according to the invention, one or more bikes 2, 3, 2 ', 3' may be provided with individual landing gear drives. This requires a known drive motor, for example suspended from the chassis frame 4, 4 ', and preferably arranged in the seat 34, 34' of the car body 8, 8 '. The drive for one or more bikes 33, 33 'is then carried out by means of a PTO shaft through an angular gear which can be arranged arbitrarily at the center of the shaft or outside the shaft. In a further embodiment, a direct drive can be used using a known wheel hub motor.
