Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to an automobile shock absorber structure. Background technique [0002] Shock absorber is a device to accelerate the attenuation of vibration of the frame and body to improve the ride comfort (comfort) of the car. The suspension system of most cars is equipped with a shock absorber. The shock absorber is an important part of the car, and its performance directly affects the comfort, handling stability and safety of the car. In the prior art, the commonly used hydraulic shock absorber has a complicated structure, and the inner wall surface of the cylinder body is usually designed as a stepped structure, which is difficult to process on the inner wall of the cylinder body and costs high. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned existing production technology, the applicant provides a shock absorber structure for automobiles with ...
