Railway vehicle anti-creeping buffering structure

Abstract

The invention relates to a railway vehicle anti-creeping buffering structure which comprises a buffering beam, traction beams, a vehicle hook base, an anti-creeping energy absorbing structure and a vehicle hook energy absorbing structure. The vehicle hook base is fixedly connected to the end portions, located at the crosswise middle position of a vehicle body chassis, of the traction beams, the vehicle hook energy absorbing structure is fixedly connected to the vehicle hook base, the anti-creeping energy absorbing structure is fixed to the middle position of the buffering beam and comprises an anti-creeping tooth and two energy absorbing pipes, the anti-creeping tooth is fixed to the front ends of the two energy absorbing pipes, and the rear ends of the energy absorbing pipes are fixed to the vehicle hook base. According to the railway vehicle anti-creeping buffering structure, the anti-creeping energy absorbing structure and the vehicle hook energy absorbing structure are connected to the parts, located at the crosswise middle position of a vehicle body, of the traction beams, the effective energy absorbing length can be increased, the energy absorbing amount is increased to the maximum, and mutual interference of the anti-creeping energy absorbing structures on the end portions of two vehicles when the vehicles pass through curves is avoided.

Description

technical field [0001] The invention relates to an anti-climbing buffer structure of a rail vehicle, in particular to an anti-climbing buffer structure at the end of a car body in which an anti-climber is arranged in the transverse middle of the car body, and belongs to the field of rail vehicle body manufacturing. Background technique [0002] The impact-resistant car body technology is called the train passive safety protection technology in the rail vehicle industry. When a train collision accident occurs, the special energy-absorbing device on the car body will deform in a controllable and orderly manner to absorb the energy generated during the collision. , in order to reduce the acceleration generated during the collision, so that the car body in the passenger compartment area does not deform and protect the safety of passengers. [0003] Europe has in-depth research in this area, and the corresponding standards are relatively sound, including EN15227, TSI, GM / RT2100, ...

AI Technical Summary

Problems solved by technology

[0005] The anti-climbing devices of most of the existing subway vehicles in China are arranged on the positions close to the two sides of the car body, which prevents the energy-absorbing capacity of the anti-climbing energy-absorbing device and the coupler energy-absorbing device from being exerted to a certain extent, and in When the train passes through the curved path, the anti-climbing energy-absorbing devices at the two car ends will interfere with each other
