Abstract

A rail vehicle having an attached deformation zone is presented. The rail vehicle has at least one end transverse beam provided in an end face region and corner pillars arranged substantially vertically and extend from the end transverse beam. The deformation zone is provided at the end face having a front transverse beam arranged parallel to the end transverse beam and spaced therefrom in an end-face direction and at least one force transmission element arranged between the end transverse beam and the front transverse beam. The element transmits longitudinal compressive forces between the end transverse beam and the front transverse beam without plastic deformation up to a defined value and failing when the defined value is exceeded.

First claim

The invention claimed is:

1. A rail vehicle, comprising:
a deformation zone provided on an end face side, said deformation zone having:
at least one end transverse beam provided in an end face area,
end pillars arranged substantially vertically extending from the end transverse beam,
a front transverse beam disposed in parallel to the end transverse beam spaced away from the end transverse beam in an end face direction,
at least one force transmission element disposed between the end transverse beam and the front transverse beam,

wherein the force transmission element transmits longitudinal pressure forces between the end transverse beam and the front transverse beam up to a specific value plastically without deformation and fails when the specific value is exceeded,
wherein the force transmission element is constructed from plates arranged in an X shape,
wherein an intersection line of the plates arranged in the X shape of the force transmission element is disposed transverse to a longitudinal direction of the vehicle; and
the deformation zone further including at least one deformation element so that a deformation of the at least one deformation element only occurs after the failure of the force transmission element.

2. The rail vehicle as claimed in claim 1 , wherein the at least one deformation element comprises an aluminum honeycomb construction, or a metal foam, or a tubular profile.

3. The rail vehicle as claimed in claim 1 , wherein at least one transverse pillar is disposed between the front transverse beam and a corner pillar.

4. The rail vehicle as claimed in claim 1 , wherein a subframe of the rail vehicle between a center of a wagon and the end transverse beam comprises at least one inner deformation element.

5. The rail vehicle as claimed in claim 4 , wherein the at least one inner deformation element comprises an aluminum honeycomb construction, or a metal foam, or a tubular profile.

6. The rail vehicle as claimed in claim 1 , wherein the deformation zone comprises paneling that covers components of the deformation zone.

7. The rail vehicle as claimed in claim 6 , wherein the paneling is made from a plastic.

8. The rail vehicle as claimed in claim 1 , wherein the deformation zone is provided at both end face sides of the rail vehicle.
