Front end structure of railway vehicle

Abstract

The invention discloses a front end structure of a railway vehicle. The vehicle front end structure comprises a vehicle body, a chassis front end structure, a cab framework and an anti-creeper; the chassis front end structure comprises a cab floor surface, a coupler supporting beam, a coupler mounting cross beam and a coupler front supporting beam; an anti-collision wall is arranged at the front end of the cab floor surface, and the anti-creeper is fixed at the front end of the anti-collision wall; the cab framework comprises a column A, a column B and cab side beams; the vehicle is sequentially divided into a hook buffer system energy absorption area, an anti-creeper energy absorption area, a vehicle body first-stage deformation energy absorption area, a vehicle body second-stage deformation energy absorption area and a vehicle body from the front end to the back end; and when the vehicle is collided, the hook buffer system energy absorption area, the anti-creeper energy absorption area, the vehicle body first-stage deformation energy absorption area and the vehicle body second-stage deformation energy absorption area deform and absorb energy in sequence. According to the front end structure of the railway vehicle, the living space of a driver can be guaranteed to the greatest extent when an accident occurs.

Description

technical field [0001] The invention relates to a rail vehicle front end structure, belonging to the technical field of rail vehicles. Background technique [0002] The most important mission of railway vehicles is to ensure the safety of drivers and passengers. Anti-climbing devices with energy-absorbing functions are usually installed at the front end of the train, which can significantly improve the deformation and energy-absorbing characteristics of rail vehicles in the event of a collision. In order to effectively prevent the trains from climbing each other during a collision, the anti-climbing device also needs to have excellent anti-sag ability, so the anti-climbing device is usually equipped with a guide mechanism with a high vertical stiffness to ensure the anti-climbing performance. The guide mechanism can ensure that the anti-climber retreats stably when the car crashes, and guides the energy-absorbing element to normally perform the deformation and energy-absorb...

AI Technical Summary

Problems solved by technology

This scheme does not set up a detachable anti-climbing device, and the anti-climbing teeth are directly fixed on the front structure of the chassis, and no special vertical anti-bending device is provided.

[0008] In addition, most rail trains, including the above-mentioned patented scheme, do not consider the protection of drivers at higher collision speeds

When the impact energy of the train is greater, the deformation of the front end of the car body will be greater, and equipment such as the driver's cab frame and driver's station will move backward during the collision process, encroaching on the driver's living space, and ultimately endangering the driver's safety
