Abstract

A rail vehicle has a bogie which rolls on a track in a direction of travel, a vehicle structure which is supported on the bogie, a rigid carrying structure which is arranged on the end side of the rail vehicle, and an end-side coupling opening through which a coupling extends for coupling further rail vehicles. A coupling securing device secures the coupling to the rail vehicle. The coupling securing device has reversible securing elements which permit a reversible lifting movement counter to the direction of travel to such an extent that the coupling is retracted completely into the supporting structure. As a result of the retraction of the coupling into the cage-like carrying structure it no longer influences the crash behavior.

First claim

The invention claimed is:

1. A rail vehicle, comprising:
a bogie for rolling on a track in a direction of travel;
a vehicle structure supported on said bogie;
a rigid support structure disposed at an end side of the rail vehicle and having an end-side coupling opening;
a coupling extending through said end-side coupling opening for coupling further rail vehicles;
a coupling securing device for securing said coupling to the rail vehicle, said coupling securing device having reversible securing elements configured to permit a reversible stroke movement counter to the direction of travel to thereby completely retract said coupling in said support structure for precluding detrimental effects of said coupling on a crash behavior of the rail vehicle.

2. The rail vehicle according to claim 1 , wherein said coupling is an automatically coupling train coupling.

3. The rail vehicle according to claim 1 , wherein said coupling securing device is configured to be subject to tension and compression, and said securing device has an internally hollow securing sleeve into which a securing plunger projects, and wherein said securing plunger is supported in said securing sleeve by a spring.

4. The rail vehicle according to claim 1 , wherein said supporting structure includes a ride-up protection device which, in the event of a collision with an obstacle, prevents the rail vehicle from riding up over the obstacle or vice versa.

5. The rail vehicle according to claim 1 , wherein said supporting structure comprises a plateau section which is part of said vehicle structure, and further comprising a guard iron receiver arranged underneath said plateau section for securing a guard iron that is permanently connected to said plateau section.

6. The rail vehicle according to claim 5 , wherein said guard iron receiver is connected to said plateau section by a further securing device, wherein said further securing device, said plateau section and said guard iron receiver form a coupling cage which delimits said coupling opening on the end side.

7. The rail vehicle according to claim 6 , wherein said coupling cage forms a jacking position, and wherein said support structure has a stability to permit a jacking up of the rail vehicle at the jacking position.

8. The rail vehicle according to claim 5 , wherein said supporting structure includes ribs forming a ride-up protection device which, in the event of a collision with an obstacle, prevents the rail vehicle from riding up over the obstacle or vice versa, and wherein said ribs project out of a front end face of said plateau section.

9. The rail vehicle according to claim 5 , wherein said plateau section extends in a longitudinal direction and a transverse direction, so that a horizontal surface is formed, and wherein said securing device is mounted to an underside of said horizontal surface.

10. The rail vehicle according to claim 5 , wherein said securing device includes reinforcement plates, which form perpendicular side wall sections.

11. The rail vehicle according to claim 1 , which comprises energy absorption elements at a head end of the rail vehicle, wherein said supporting structure projects beyond said energy absorption elements in the direction of travel.

12. The rail vehicle according to claim 11 , wherein an uppermost point of said supporting structure has a clearance h of less than 1500 mm from a plane defined by wheel contact points at which wheels of said bogie are in contact with rails of the track.
