Control vehicle and vehicle body thereof

Abstract

The embodiment of the invention relates to the technical field of railway vehicles, in particular to a control vehicle and a vehicle body thereof. The vehicle body comprises a bottom frame, an end wall, a side wall, a vehicle roof and a cab. The cab comprises a cab framework, a front-end energy absorption structure, a front-end car coupler joist and an anti-climbing structure; the anti-creeping structure is mounted on one side, deviating from the bottom frame, of the cab framework through the front-end energy absorption structure; the front-end car coupler joist is mounted at the bottom of the anti-climbing structure; a rear end energy absorption structure is connected between the bottom frame and the end wall; the front end energy absorption structure and the rear end energy absorption structure absorb collision energy through compression deformation in the collision process; and doorways are formed in the side walls corresponding to the two end parts of the middle underframe. According to the vehicle body, the buffering and energy absorbing functions can be achieved when the vehicle body collides, the body of a passenger is prevented from being injured, and the riding comfort of the passenger can be improved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular to a control vehicle and its vehicle body. Background technique [0002] Existing double-layer stainless steel cars are mainly used in European and American countries, and stainless steel car bodies are an effective way for car body anticorrosion and light weight. The stainless steel car body part is a thin-walled cylindrical overall load-bearing structure composed of an underframe, side walls, end walls, roof, second-floor floor and driver's cab. [0003] The doorways of the existing car body are mainly distributed on the end chassis, and one side wall is provided with doorways at both ends, and the doorways at the two ends of the car body are provided with stairs for passengers to get on and off the car. The underframe of the car body and the side wall are connected by a tension pillow structure, and the protruding part of the underframe is welded so that the two ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the door cannot be arranged in the middle fishbelly area of ​​the underframe of the car body, so that passengers can only enter a lower platform from a higher platform after entering the car body, which makes the driving experience of passengers poor

At the same time, the underframe of the car body adopts the rigid connection of the pillow cushion structure. When the car body collides, the buffering and energy absorption effect cannot be realized, and the collision force will be directly transmitted to the car body, causing damage to the body of the passengers.
