Diameter change type hydraulic buffer structure automobile shock absorber assembly

Abstract

The invention provides a diameter change type hydraulic buffer structure automobile shock absorber assembly, and relates to the technical field of automobile parts. The diameter change type hydraulicbuffer structure automobile shock absorber assembly comprises a body. A work cylinder is arranged in the body. A guide device is arranged on the end portion of the work cylinder. Necking diameter change processing is conducted on the end, close to the guide device, of the work cylinder. A piston rod is arranged in the work cylinder. The free end of the piston rod penetrates through the guide device and extends to the outer portion of the body. The portion, located on the area subjected to necking diameter change, in the work cylinder is arranged into a buffer zone. An inner limiting part is arranged on the outer surface of the piston rod. A buffer is fixedly installed on the outer surface of the inner limiting part. By conducting necking diameter change processing on the work cylinder, thedamping of the buffer zone can be larger than two or more times of the normal shock absorber recovery damping force, the buffering power value is increased in a doubled manner according to the reciprocation speed, and a strong buffering effect is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile shock absorber assembly with variable diameter hydraulic buffer structure. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, the suspension system of the car is generally equipped with a shock absorber. The shock absorber is a vulnerable part during the use of the car. The performance of the shock absorber will directly affect the driving stability of the car and the life of other parts. Therefore, the shock absorber should always be in good working condition. [0003] During the use of conventional automobile shock absorbers, if the car is driving in bad road conditions such as bumps and potholes, the vibration of the shock absorber is relatively large compared to that of the flat road surface, and it is easy to stretch the shock absorber to the stretchin...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a variable-diameter hydraulic buffer structure automotive shock absorber assembly, which solves the problem that the internal guide structure of the shock absorber collides with the internal limit of the piston rod for a long time, which may easily cause damage to the internal parts of the shock absorber. , which in turn causes the shock absorber to fail, and there is also a design of setting a buffer spring inside the shock absorber, but the spring in this design has a linear force value, and the elastic force is relatively small, so it cannot play a significant role in the buffering process.
