Shock absorber, shock absorber control system and automobile

Abstract

The invention discloses a damper. The damper comprises a working cylinder (1), the working cylinder comprises a cylinder body (2) and a piston rod (3), a valve seat (21) is arranged at one end of the cylinder body, the piston rod extends into the cylinder body from the other end of the cylinder body, a piston of the piston rod divides the cylinder body into a rod cavity and a rodless cavity, the damper further comprises a through-flow pipeline (4), a diversion trench (22), an adjusting valve (5) and a control motor (6), the rod cavity and the rodless cavity of the working cylinder are communicated with each other through the through-flow pipeline (4), the diversion trench (22) is formed in the valve seat and communicated with the through-flow pipeline, the adjusting valve (5) is arranged in the diversion trench (22) and used for adjusting flow, and the control motor (6) is used for controlling flow opening degree of the adjusting valve. The invention further provides a vibration damping control system and an automobile. By means of the technical scheme, the damper can be adapted to different automobile driving conditions, effective vibration damping and powerful and even rigid supporting are provided for the whole automobile body, sustained vibration, excessive pitching, excessive listing, even side turning and the like of the automobile body can be effectively prevented, and safe and stable operation of the whole automobile can be guaranteed.

Description

technical field [0001] The invention relates to automobile chassis technology, in particular to a shock absorber, a shock absorber control system and an automobile. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort of cars, the safety of passengers and goods. [0003] At present, in the automobile chassis, shock absorbers are usually used to connect the axle and the body to suppress vibration. When the road surface is bumpy, although the vibration-absorbing spring can filter the vibration of the road surface, the reciprocating motion of the spring itself will still cause the body to bump up and down. The shock absorber is used to suppress this spring jump. If the resistance of the shock absorber is too small, the vehicle body will hop up and down; if the resistance of the shock absorber is too high, it will hinder the spri...

AI Technical Summary

Problems solved by technology

[0005] However, the existing shock absorbers are usually of a mechanical structure, so the resistance generated by them is fixed, and it is difficult to adapt to various driving conditions of the car, especially when the car is in extreme conditions such as sharp turns, emergency braking and rapid acceleration. It is easy to cause the vehicle to roll over or pitch, etc.
