Vibration absorber dust-proof cover

Abstract

A vibration absorber dust-proof cover comprises at least three sleeves, namely an upper sleeve, a lower sleeve and a connecting sleeve, sleeved from outside to inside. The ends of the sleeves are provided with inward or outward hooks; the inner diameter of the upper sleeve is largest, the inner diameter of the connecting sleeve is intermediate, the inner diameter of the lower sleeve is smallest, the rear two sleeves can be telescoped into or out of the upper sleeve completely, and the sleeves are connected through the inward and outward hooks sequentially. The dust-proof cover has the advantages that the characteristic of large-ratio axial size change is provided, the effects of vibration absorption and dust proofing can be achieved during wheel bounce, the internal parts of the vibration absorber can be protected from external sand and earth invasion, and the service life of the vibration absorber is prolonged; the dust-proof cover is in a multi-segment combined structure, after one part is broken due to external force, the part can be changed independently, and maintaining cost is reduced.

Description

technical field [0001] The invention relates to the field of the suspension of the driving system of the automobile chassis, in particular to a shock absorber dust cover. Background technique [0002] Shock absorber is an important part of automobile chassis suspension system. When the car body and wheels vibrate, the friction of the liquid in the shock absorber when it flows through the damping hole and the viscous friction of the liquid form a vibration resistance, which converts the vibration energy into heat energy and dissipates it into the surrounding air, thereby achieving rapid attenuation purpose of vibration. Therefore, shock absorbers play a vital role in vehicle handling stability and ride comfort. [0003] Generally, there is an important part installed on the outside of the shock absorber cylinder, that is, the dust cover. The function of the dust cover is to protect the shock absorber piston rod, oil seal, buffer block and other internal parts from or less ...

AI Technical Summary

Problems solved by technology

However, due to the soft base material, the radial strength of the dust cover is also low, and radial permanent deformation or damage will occur under the action of external force, and when the radial deformation or damage of the dust cover occurs, the connection cannot effectively prevent dust. As a result, the shock absorber is polluted by sand and eventually leads to functional failure
