Embodiment

[0018] Example: such as Figure 1 to Figure 3 As shown, a bushing for an automobile swing arm includes two bushes that are respectively press-fitted on both ends of the swing arm sleeve 11 in the axial direction. The swing arm sleeve 11 is located on the swing arm body. The swing arm sleeve 11 is a cylindrical structure. The bushing comprises an outer ring 1 , an inner ring 3 and a damping rubber layer 2 arranged between the outer ring 1 and the inner ring 3 . Both the outer ring 1 and the inner ring 3 are cylindrical structures. The swing arm sleeve 11 is sleeved on the outer ring 1 . There is an interference fit between the outer ring 1 and the swing arm bushing 11 . The outer ring 1 and the inner ring 3 are arranged coaxially. One end of the outer ring 1 is folded outward to form a first flange 4 matching with the end of the swing arm sleeve 11 . The first flange 4 is circular. One side of the first flange 4 is in contact with the end surface of the swing arm sleeve ...

Abstract

The invention provides an automobile swing arm lining. The automobile swing arm lining comprises two linings respectively sleeving two axial ends of a swing arm casing tube through press fitting, wherein each lining includes an outer ring, an inner ring and a damping rubber layer which is arranged between the outer ring and the inner ring; and a skeleton with adjustable rigidity is arranged in thedamping rubber layer. The automobile swing arm lining effectively improves the axial rigidity of the automobile swing arm lining, reduces the risk of damaging the lining, can conveniently adjust theaxial rigidity of the lining by the current magnitude, can adapt to different road impact situations, and can satisfy the demand for different users.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile swing arm bushing. Background technique [0002] The car swing arm is part of the car suspension system. The car swing arm is assembled by ball pin, swing arm body and bushing. Among them, the bushing is press-fitted in the swing arm casing in the swing arm body, which is used to buffer the lateral and longitudinal impact of the road on the steering gear and improve driving comfort. The existing bushing is integrally vulcanized by an inner ring, an outer ring and rubber, and the bushing is pressed into the swing arm casing by a press. However, in order to meet the comfort of the car when driving, the existing bushing usually reduces the hardness of the rubber material, which will reduce the axial stiffness of the bushing. When the car is used for a long time or encounters a large impact on the road surface, There is a risk of the rubber being torn, resulting ...
