Shock absorber and vehicle provided with the same

Abstract

The invention relates to the technical field of vehicles, in particular to a suspension damper and a vehicle provided with the damper, which have the advantages of good dust prevention effects and prevention of oil leakage. The damper comprises an oil storing cylinder and a dust-proof sleeve, wherein the dust-proof sleeve is made of elastic rubber; one end of the dust-proof sleeve is hermetically connected with an upper hanging ring; the other end of the dust-proof sleeve is hermetically connected with the oil storing cylinder; vent holes are formed in the dust-proof sleeve. A wrapping corrugated structure is adopted, so that particles such as welding slag and sand are effectively prevented from entering a damper oil barrel and scratching the inner wall of a working cylinder, a piston rod and an oil seal, and oil leakage, abnormal sound and the like of the damper are avoided; the two ends of the dust-proof sleeve are clamped very tightly, so that the problems of falling and the like of the dust-proof sleeve during driving are solved; the dust-proof sleeve is simple in structure and can be deviated and deflected, flexible motion of the oil storing cylinder of the damper can be realized, the dust prevention effect is further enhanced, and the service life of the damper is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a suspension shock absorber and a vehicle provided with the shock absorber, in particular to a suspension shock absorber with good dust-proof effect and capable of preventing oil leakage and a suspension shock absorber equipped with the shock absorber device vehicles. Background technique [0002] In the chassis suspension system, the shock absorber is an important safety part, and its performance is very important. From the perspective of common market problems, oil leakage and abnormal noise of the shock absorber have always been troubled by various vehicle OEMs and shock absorber manufacturers. According to research and analysis, an important reason for such quality problems is that the cleanliness of the shock absorber is not enough, usually welding slag, sand and other particles intrude into the shock absorber oil cylinder, scratch the inner wall of the working cylinder and...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to solve the problem that the end cover of the metal dustproof cover of the existing shock absorber will get rusty, the seal is not tight, there is dynamic interference in the working cylinder, the cleanliness of the shock absorber is not enough, welding slag, sand and other particles It is easy to intrude into the oil cylinder of the shock absorber, scratch the inner wall of the working cylinder, the piston rod and the oil seal, and cause oil leakage and abnormal noise of the shock absorber
