Abstract

A device for preventing rail vehicles from riding up includes an energy absorbing element extended in longitudinal direction, having a hollow inside, a fastening side for fastening to one of the rail vehicles and an impact side facing away from the fastening side. A flange fastened to the impact side of the energy absorbing element has an impingement surface facing away from the fastening side. The flange protrudes in at least one vertical direction beyond a contour delimited by the energy absorbing element on the impact side, forming a holding web protruding beyond the energy absorbing element. The device provides effective ride-up protection for identically and differently equipped rail vehicles by equipping a free end of the holding web with at least one vertical stop extending up from the impingement surface, and providing a device for moving the vertical stop upon an impact loading in longitudinal direction.

First claim

The invention claimed is:

1. A device for preventing rail vehicles from riding up, the device comprising:
an energy absorbing element extending in a longitudinal direction and having a hollow inside, a fastening side configured to be fastened to one of the rail vehicles, an impact side facing away from said fastening side and a contour delimited by said impact side;
a flange fastened to said impact side and having an impingement surface facing away from said fastening side, said flange projecting beyond said contour in at least one vertical direction to form a holder web projecting beyond said energy absorbing element and having a free end;
a vertical stop disposed at said free end of said holder web and projecting from said impingement surface; and
a device for shifting said vertical stop in said longitudinal direction during an impact stress, said device for shifting said vertical stop including a fastening device for fastening said vertical stop to said holder web and permitting said vertical stop to shift in said holder web towards said fastening side in the event of the impact stress.

2. The device according to claim 1 , wherein said device for shifting said vertical stop is formed by dimensioning said holder web to be bent in said longitudinal direction towards said fastening side in the event of the impact stress.

3. The device according to claim 1 , wherein said impingement surface protrudes beyond said contour of said impact side of said energy absorbing element ( 2 ) in two vertical directions facing away from one another.

4. The device according to claim 1 , wherein said energy absorbing element has a guide tube extending out within said energy absorbing element from said impact side to said fastening side.

5. The device according to claim 4 , wherein said guide tube is configured to engage in a cutout provided in the rail vehicle.

6. The device according to claim 5 , which further comprises guide elements for telescopically extending said guide tube through to the cutout.

7. A rail vehicle, comprising two of the devices according to claim 6 .

8. A rail vehicle, comprising a device according to claim 1 .

9. A device for preventing rail vehicles from riding up, the device comprising:
an energy absorbing element extending in a longitudinal direction and having a hollow inside, a fastening side configured to be fastened to one of the rail vehicles, an impact side facing away from said fastening side and a contour delimited by said impact side;
a flange fastened to said impact side and having an impingement surface facing away from said fastening side, said flange projecting beyond said contour in at least one vertical direction to form a holder web projecting beyond said energy absorbing element and having a free end;
a vertical stop disposed at said free end of said holder web and projecting from said impingement surface, said vertical stop being a stop web extending at right angles to said holder web; and
a device for shifting said vertical stop in said longitudinal direction during an impact stress.

10. A device for preventing rail vehicles from riding up, the device comprising:
an energy absorbing element extending in a longitudinal direction and having a hollow inside, a fastening side configured to be fastened to one of the rail vehicles, an impact side facing away from said fastening side and a contour delimited by said impact side;
a flange fastened to said impact side and having an impingement surface facing away from said fastening side, said impingement surface having ribs, said flange projecting beyond said contour in at least one vertical direction to form a holder web projecting beyond said energy absorbing element and having a free end;
a vertical stop disposed at said free end of said holder web and projecting from said impingement surface; and
a device for shifting said vertical stop in said longitudinal direction during an impact stress.
