Abstract

The invention relates to the technical field of vehicle accessories, in particular to a liner assembly and an assembling method thereof, a shock absorber and a vehicle. The liner assembly comprises aliner component and a fixing ring for being connected with the bottom of the shock absorber body of the shock absorber; the liner component comprises a sleeve and a rubber liner body; the rubber linerbody is arranged on the outer surface of the sleeve in a sleeving manner; the fixing ring is arranged on the outer surface of the rubber liner body in a sleeving manner; a circumferential bulge is arranged on the outer surface of the sleeve corresponding to the fixing ring; and a circumferential groove matched with the circumferential bulge is formed on the rubber liner body. The assembling method of the liner assembly is used for assembling the liner assembly. The shock absorber comprises the liner assembly. The vehicle comprises the shock absorber. According to the liner assembly and the assembling method thereof, the shock absorber and the vehicle, the weight of the rubber liner body is reduced to further reduce the weight of the liner assembly, improve the rigidity of the rubber linerbody and improve the reliability of the liner assembly; and assembling is convenient, so that the assembling efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of vehicle accessories, in particular to a bushing assembly and an assembly method thereof, a shock absorber and a vehicle. Background technique [0002] During the driving process of the car, vibrations are generated by the impact of the road surface. In order to overcome the vibration during driving and improve the comfort performance, shock absorbers are widely used in cars. [0003] The shock absorber bushing is a commonly used secondary shock absorber connected with the shock absorber. A shock absorber bushing in the related art forms a bushing assembly through an inner sleeve, an outer sleeve, and a rubber body, and presses the bushing assembly into a fixing ring through a press, and the outer sleeve and the fixing ring form an interference fit , so that the bushing assembly is attached to the shock absorber body. Among them, the inner casing is a straight casing, and the radial stiffness o...
