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

Embodiment Construction

[0067] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0068] Such as figure 1 As shown, the rail vehicle front end structure of this embodiment mainly includes a car body body 1 , an underframe front end structure 2 , a driver's cab framework 3 and an anti-climbing device 4 . The vehicle body 1 is mainly used for accommodating passengers and installing on-board equipment, and is the area with the highest longitudinal strength of the vehicle body. The front end structure 2 of the underframe is an extension ...

Abstract

The present invention disclosed the front -end structure of the rail vehicle.The front -end structure of the vehicle includes the body body, the front -end structure of the chain, the driver's room skeleton and the anti -climber;The front end of the driver's room floor has a collision wall, which is fixed at the front end of the collision wall;In order to hook the system's energy -absorbing area, anti -climber energy absorbing area, vehicle body first -level deformation absorption area, car body secondary deformation energy absorption zone, and car body body; when the vehicle collides, the hook slow system absorption energy absorption energy absorption energy absorption energy absorption energy absorption energyArea, anti -climber -absorbing zone, first -level deformation absorption zone, and second -level deformation absorption zone of the car body occur in turn.The present invention can ensure the driver's living space at the time of the accident.

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...
