Shock absorber convenient to install for bullet train

Abstract

The invention relates to the field of shock absorbers for bullet trains, in particular to a shock absorber convenient to install for a bullet train. The shock absorber comprises a main body, a wrapping mechanism, a pin tightening mechanism, a non-return mechanism, a rotating mechanism and a fixing mechanism. Through the arrangement of the wrapping mechanism, the main body can conveniently offset part of eccentric force formed in the movement process while stretching out and drawing back, stable operation of the bullet train is facilitated, through the arrangement of the non-return mechanism, the non-return effect can be achieved on rotation of parts in the wrapping mechanism according to needs, through the arrangement of the rotating mechanism, more labor is saved during rotation, operation can be conducted in a small space, the using effect of the shock absorber is improved, through the arrangement of the pin tightening mechanism, the installation process can be simpler, faster, time-saving and labor-saving, the installation or replacement efficiency is improved, through the arrangement of the fixing mechanism, the main body is installed on a beam column more firmly, the replacement process is simple, and the replacement efficiency is further improved.

Description

technical field [0001] The invention relates to the field of shock absorbers for motor vehicles, in particular to a shock absorber for motor vehicles that is easy to install. Background technique [0002] EMUs, the full name of power vehicles, refer to vehicles equipped with power devices in the rail transit system, including locomotives and power carriages. The motor car is equipped with driving wheels, and the corresponding non-driving device vehicle is a trailer. For the train to run normally on the track, there must be a moving car to provide sufficient traction for the entire train, but it is not necessary to hang an unpowered trailer. The moving car needs to be installed on the shock absorber during the manufacturing process. The shock absorber is used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. It is widely used in automobiles to accelerate the attenuation of frame and body vibrations and improve the...

AI Technical Summary

Problems solved by technology

[0003] However, in order to suppress the vibration of the body of the train when it is in motion, an appropriate number of shock absorbers will be installed during the process of manufacturing the train. Most of the traditional shock absorbers are installed in modules. Each set of wheels The shock absorber and the shock absorber are installed first, and finally assembled together. When the shock absorber of the motor vehicle is aged for a certain number of years, it needs to be replaced. It is extremely inconvenient, and the frequency of train departures is relatively intensive, which limits the time required for replacement, making the replacement must be completed within the rated time, increasing the intensity of the replacement work
