Problems solved by technology

[0006] In order to overcome the problem that the gas in the groove in the rubber layer will affect the strength of the bushing, the problem of peeling off the rubber layer and the steel bushing, and the relative rotation between the plastic bushing and the steel bushing, a composite bushing for automobile shock absorbers is proposed. And automotive shock absorber technical solutions

Abstract

The invention relates to an automobile shock absorber bushing and a shock absorber. The automobile shock absorber bushing comprises a sleeve body connected with a shock absorber body, an inner sleeve and a rubber base body, wherein the rubber base body is fixed to the outer surface of the inner sleeve, a plastic bushing is fixed to the inner wall of the inner sleeve, an oil return groove is formed in the inner wall of the plastic bushing, at least one annular protrusion is formed on the outer surface of the rubber base body, an annular concave groove matched with the annular protrusion is formed in the inner wall of the sleeve body, and at least two axial penetrating through holes are formed in the end surface of the rubber base body.

Description

technical field [0001] The invention belongs to the field of shock absorbers in automobile parts, in particular to an automobile shock absorber bushing and a shock absorber using the bushing. Background technique [0002] During the driving process of the car, especially the suspension system is subjected to the impact of the road surface to generate vibration. In order to overcome the vibration during the driving process and improve the comfort performance, shock absorbers are widely used in the suspension system of the car. The current shock absorber in the automotive field is a hydraulic shock absorber. Its working principle is that when the vehicle body and the axle are vibrated to generate relative motion, the piston in the shock absorber moves up and down, and the shock absorber oil in the shock absorber cavity is released. Repeatedly flow from one cavity through the pores to another cavity. At this time, the friction between the hole wall and the oil and the friction ...
