AI Technical Summary

Technical Problem

It is difficult for existing passive rubber shock absorbers to effectively adjust the damping parameters at different excitation frequencies, resulting in poor vibration isolation effect.

Method used

A variable damping shock absorber is designed to adjust the opening size of the inner oil cavity and the outer oil cavity by allocating valve, so as to dynamically adjust the damping rate and adapt to different incentive frequencies.

Benefits of technology

Adjust the damping parameters at different incentive frequencies to ensure that the shock absorber is always in a better vibrational state, which improves the vibration isolation effect.

Abstract

The present invention provides a variable damping shock absorber, which relates to the technical field of vibration isolation equipment. The variable damping shock absorber provided by the present invention includes a cylinder body, a piston assembly and a distribution valve. Along the axial direction of the piston assembly, the piston assembly is slidably inserted at both ends of the cylinder body and forms an inner oil chamber between the cylinder body. The cylinder body has an outer oil chamber, and the inner oil chamber and the outer oil chamber are connected through a connecting channel on the cylinder body. The distribution valve is arranged in the inner oil chamber, and the distribution valve is used to adjust the size of the opening of the connecting channel. The variable damping shock absorber provided by the present invention can adjust its own damping parameters for different excitation frequencies to ensure that it is always in a better vibration isolation parameter.
