Motor train unit head train passive safety protection device

Abstract

The invention relates to a motor train unit head train passive safety protection device which comprises coupler and draft gear components, anti-creeper components and a main energy absorber component, wherein the main energy absorber component is mounted at the front end of a head train body bumper rail, the coupler and draft gear components are arranged in the front of the main energy absorber component and mounted on guard plates of two sides of the front end of the head train body bumper rail, and the anti-creeper components are arranged on two sides of the guard plates. The protection device is simple in structure, reasonable in layout and high in reliability, energy can be sufficiently and reasonably absorbed when a train collides, life and property safety of passengers is guaranteed, and structural integrality of a rail train body is furthest maintained.

Description

technical field [0001] The invention belongs to the technical field of anti-climbing and energy-absorbing passive safety protection for high-speed EMUs, and in particular relates to a passive safety protection device for a head car of a high-speed train. Background technique [0002] With the rapid development of my country's rail transit construction, while travel is more convenient, the harm caused by accidents is also increasing. While improving the reliability of active control, the passive safety of rail buses has gradually become the focus of attention. Since the leading car has the greatest impact force when a rail train collides, and the following cars decrease step by step, therefore, considering the energy absorption requirements of trains and the actual energy absorption method, an absorbing device with more energy is usually arranged on the leading car of the train. [0003] At present, rail transit vehicles usually arrange energy absorbing devices at both ends o...

AI Technical Summary

Problems solved by technology

[0003] At present, rail transit vehicles usually arrange energy-absorbing devices at both ends of the train, but due to the various forms and arrangements of absorbing devices, on the one hand, due to the large ratio of peak force to average force of some forms of energy-absorbing devices , The impact load fluctuates greatly, resulting in low overall energy absorption efficiency of the energy absorbing device; on the other hand, due to the unreasonable structural layout and design, higher requirements are put forward for the car body, and even the load of some buffer energy absorbing devices is too concentrated , the local car body strength requirements for its installation parts are very high, and it is difficult to meet the strength bearing requirements in car body design

For example: commonly used expansion tube energy absorption, shrink tube energy absorption, cutting energy absorption, vehicle end structure energy absorption (such as anti-collision column energy absorption, etc.) all have unreasonable energy distribution of energy absorption components and low efficiency of collision energy absorption. High, unreasonable requirements for the local strength of the car body, etc.
