Abstract

A rail vehicle includes a fuel tank having a tank wall delimiting a tank interior space for storing fuel. At least portions of a first support are connected to the tank wall. A longitudinal support includes first and second longitudinal support portions being offset in longitudinal direction of the vehicle. The fuel tank is disposed in longitudinal direction between the first and second longitudinal support portions. The first support is coupled to the first and second longitudinal support portions. At least portions of the first support are disposed in the tank interior space in the longitudinal direction. The first support running in the longitudinal direction is disposed between the first and second longitudinal support portions. The first support is configured for fully transmitting a force acting between the first and second longitudinal support portions in longitudinal direction of the vehicle.

First claim

The invention claimed is:

1. A rail vehicle, comprising:
a drive unit of the rail vehicle;
a mounting device for mounting said drive unit;
a longitudinal support including a first longitudinal support portion and a second longitudinal support portion being mutually offset in a longitudinal direction of the rail vehicle;
a fuel tank disposed in said longitudinal direction between said first longitudinal support portion and said second longitudinal support portion, said fuel tank having a tank wall delimiting a tank interior space for storing a fuel and said fuel tank having at least one first support running in said longitudinal direction;
at least portions of said at least one first support being connected to said tank wall,
at least portions of said at least one first support being disposed in said tank interior space in said longitudinal direction;
said at least one first support being disposed between and coupled to said first longitudinal support portion and said second longitudinal support portion, said at least one first support including an upper brace, said mounting device being disposed on said upper brace on a side of said upper brace facing away from said tank interior space; and
said at least one first support being configured for transmitting a force acting between said first longitudinal support portion and said second longitudinal support portion in said longitudinal direction.

2. The rail vehicle according to claim 1 , wherein:
said upper brace includes a first upper brace portion and at least one second upper brace portion;
said first upper brace portion is more remote from said tank interior space than said second upper brace portion; and
said mounting device is disposed on said second upper brace portion.

3. The rail vehicle according to claim 2 , wherein:
said at least one first support has a web;
said web includes a first web portion;
said first web portion is disposed in said tank interior space;
said tank wall has a tank base;
said tank base delimits said tank interior space on a lower side; and
said first web portion is coupled to said tank base.

4. The rail vehicle according to claim 3 , wherein:
said web extends in said longitudinal direction;
said upper brace is fastened to said web on an upper side; and
said upper brace is aligned to be transverse to said web.

5. The rail vehicle according to claim 3 , wherein:
said first web portion in said tank interior space delimits a first tank interior space portion and a second tank interior space portion;
said first web portion has at least one opening formed therein; and
said opening in fluidic terms connects said first tank interior space portion to said second tank interior space portion.

6. The rail vehicle according to claim 3 , wherein:
said tank wall includes a front tank side wall and a rear tank side wall;
said front tank side wall is offset relative to said rear tank side wall;
said front tank side wall and said rear tank side wall delimit portions of said tank interior space;
said web is disposed between said front tank side wall and said rear tank side wall; and
said web includes a first longitudinal end connected to said front tank side wall and a second longitudinal end connected to said rear tank side wall.

7. The rail vehicle according to claim 3 , wherein:
said tank wall has a tank upper side for delimiting said tank interior space on an upper side;
said web includes a second web portion; and
said second web portion is disposed outside said tank interior space and protrudes beyond said tank upper side.

8. The rail vehicle according to claim 7 , wherein at least portions of said tank upper side are configured as a tub, and at least portions of said tank upper side delimit a catchment volume.

9. The rail vehicle according to claim 7 , wherein:
said fuel tank has a tank side support;
said tank side support is laterally offset relative to said at least one first support;
said tank side support laterally delimits said tank interior space;
at least one first tank transverse support is disposed between said tank side support and said at least one first support; and
said first tank transverse support connects said at least one first support to said tank side support.

10. The rail vehicle according to claim 9 , wherein said first tank transverse support extends across an entire height of said tank interior space and at least in portions is connected on an upper side to said tank upper side and on a lower side to said tank base.

11. The rail vehicle according to claim 9 , which further comprises:
a second support and at least one second tank transverse support;
said second support being laterally offset relative to said at least one first support;
said second tank transverse support being disposed between said at least one first support and said second support; and
said second tank transverse support connecting said at least one first support to said second support.

12. The rail vehicle according to claim 11 , wherein said at least one first support and said second support are identically constructed.

13. The rail vehicle according to claim 11 , wherein at least one of:
said first tank transverse support is at least one of disposed in a common plane with said second tank transverse support, or offset in said longitudinal direction relative to said second tank transverse support, or
at least one of said first tank transverse support or said second tank transverse support is perpendicular to said at least one first support or has an L-shaped profile.

14. The rail vehicle according to claim 1 , which further comprises a connector support having an external side connected to said tank wall, said connector support tapering off by way of an increasing spacing from said tank wall.
