Anti-climbing device for railway carriages

Abstract

The invention relates to an anti-climbing device (2) for railway carriages, which is fixed at least at one end of the carriage at a defined height and extends over at least part of the carriage width. To co-operate with the end section of an anti-climbing device of another carriage in the event of a crash, said device is provided with a central cut-out section (5), open on the underside and delimited on the upper side by an interception surface, said section being located beneath a central protruding end section (4), in addition to two centring surfaces (8) that laterally delimit the section (5). An essentially horizontal fixing surface (9) adjoins the lower edge of each centring surface.

Description

technical field [0001] The present invention relates to an anti-climbing device for a train carriage, which is installed at at least one end of the carriage at a predetermined height and extends across at least a part of the width of the carriage. Background technique [0002] One such anti-climbing device is known, for example, from U.S. Patent No. 4,184,434, the purpose of which is to prevent one vehicle body from colliding with the other with a certain height deviation in the event of a rear-end collision between two railway cars. Serious damage caused to the carriage of a passenger car by a vehicle body. [0003] Typically, anti-climbing devices have a plurality of parallel horizontal beams, as can be seen, for example, in Figures 1 to 3 which show the state of the art. On the partly shown railroad car 1, an anti-climbing device 2 is mounted at both ends of the car, extending substantially across the entire side of the car, and is configured to direct forces to the car ...

AI Technical Summary

Problems solved by technology

This problem is exacerbated on vehicles without continuous anti-climbing devices and with highly curved rear ends

In the event of an accident this makes the anti-climb device engagement insufficient and uncertain and affects its efficiency

[0007] Another problem that needs to be solved is that the overall height of the anti-climbing device is limited, for example due to joints, but on the other hand, it cannot be expected that the anti-climbing devices of two colliding cars will be at exactly the same height in the event of an accident

[0008] The above-mentioned problems can either result in complete failure of the anti-climbing device or cause the forces to be directed in an indeterminate manner, at least partially causing damage to the disposable elements mounted on the railway car
