Stabilizer bar bush assembly

Abstract

A stabilizer bar bush assembly comprises a stabilizer bar bush and a pressing piece. The stabilizer bar bush is a plastic part, the pressing piece is an iron part, flanges of large transitional arcs are arranged at two ends of the stabilizer bar bush, flanges of large transitional arcs are arranged on two sides of the pressing piece and are in close fit with the flanges of the large transitional arcs at the two ends of the stabilizer bar bush, and the radian R of each flange of the corresponding large transitional arc at the corresponding end of the stabilizer bar bush is 1.5-3 times of the wall thickness delta of the pressing piece; a bump is arranged on the middle upper portion of the stabilizer bar bush, a bump is arranged in the middle of the pressing piece, and the bump in the middle of the pressing piece is in close fit with the bump on the middle upper portion of the bush; and openings of the stabilizer bar bush are arranged on side surfaces of the stabilizer bar bush. The stabilizer bar bush assembly has the advantages that transverse shifting of a stabilizer bar can be effectively limited, normal operation of the stabilizer bar is guaranteed, the service life of the stabilizer bar bush can be prolonged, and noise and abnormal sound can be effectively reduced.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an automobile front stabilizer bar bush assembly. Background technique [0002] The stabilizer bar in the front suspension system of a car is usually connected to the body or parts fixed to the body through a bushing assembly; the stabilizer bar often has lateral movement during the working process, and if the movement is too large, it will affect the performance of the whole vehicle , Interference with other components, etc.; therefore, the stabilizer bushing assembly and the stabilizer bar must be installed in conjunction with each other to effectively limit the lateral movement of the stabilizer bar. [0003] The structure of the stabilizer bushing assembly currently used is as follows: figure 1 Shown: It consists of a stabilizer bar bushing 1a and a pressure block 2a, usually the bushing is rubber, and the pressure block is iron; the structure of the stabilizer bar bushing is as fo...

AI Technical Summary

Problems solved by technology

[0005]1) When the stabilizer bar 3a moves during operation, the bushing is easily pressed into the inner cavity of the pressure block by the stabilizer bar stop ring 301a, thereby losing the axis of the stabilizer bar to the limit effect;

[0006]2) The service life of the bush is not long, and it is easy to wear due to the movement of the stabilizer bar and the bush, and the contact area between the side of the pressure block and the flanging 101a of the bush is small , easy to cut off the flanging of the bushing;

[0007]3) The opening 102a of the bush is facing downwards, and the position is unreasonable. When the bush is pre-tightened, the opening is not easy to be pressed closed, resulting in the bush and the stabilizer bar Poor contact is also prone to bush wear;

[0008]4) Abnormal noises are likely to occur: the bushing moves and the pressure block rubs; after the bush flange is cut off, the limit ring of the stabilizer bar collides with the pressure block etc., which is prone to abnormal noise
