An easy-to-install shock absorber for motor vehicles

Abstract

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, including a main body, a wrapping mechanism, a tight pin mechanism, a non-return mechanism, a rotating mechanism and a fixing mechanism; through the setting of the wrapping mechanism , it can facilitate the expansion and contraction of the main body while offsetting the eccentric force formed during a part of the movement process, which facilitates the smooth operation of the train. Through the setting of the non-return mechanism, the rotation of the internal parts of the wrapping mechanism can be stopped as required The return function, through the setting of the rotating mechanism, can make the rotation more labor-saving, and can also be operated in a small space, which improves the use effect of the shock absorber. Through the setting of the tight pin mechanism, it can make the installation process It is simpler and faster, saves time and effort, and improves the efficiency of installation or replacement. Through the setting of the fixing mechanism, the main body is installed on the beam column more firmly, and the replacement process is simple, which further improves the replacement efficiency.

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] EMU, the full name of power vehicle, refers to vehicles equipped with power devices in the rail transit system, including two categories of locomotives and power cars. The motor car is equipped with driving wheels, and the corresponding non-drive vehicle is the trailer. For the train to run normally on the track, there must be an EMU to provide sufficient traction for the entire train, but it is not necessary to attach an unpowered trailer, and the EMU needs to be installed with shock absorbers during the manufacturing process. The shock absorber is used to suppress the shock and the impact from the road surface when the spring rebounds after shock absorption. Widely used in automobiles, in order to accelerate the attenuation of the vibration of the frame and the body to ...

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
