Anti-axial-disengaging wear-resistant transverse stabilizer bar bush

Abstract

The invention discloses an anti-axial-disengaging wear-resistant transverse stabilizer bar bush. The anti-axial-disengaging wear-resistant transverse stabilizer bar bush comprises a fixing support, a bush body and a framework. A bush convex rib is arranged on the surface of the bush body, annular grooves are evenly formed in the inner hole wall of the bush, and the framework is embedded into the bush body; the fixing support is matched with the outer surface of the bush body; a stabilizer bar matching part is the part, matched with the stabilizer bar bush, on a transverse stabilizer bar, and the diameter of the stabilizer bar matching part is gradually reduced from the middle to the two edges. The bush body is prepared from materials such as natural rubber, butadiene styrene rubber, butadiene rubber, copolymerization-type epichlorohydrin rubber and ethylene-vinyl acetate rubber in a processed mode. By means of the anti-axial-disengaging wear-resistant transverse stabilizer bar bush, the stabilizer bar and the stabilizer bar bush have the enough axial rigidity, axial disengaging of the stabilizer bar bush is limited accordingly, and abrasion of the bush inner-hole rubber material is reduced, and an abnormal sound generated between the stabilizer bar and the stabilizer bar bush in the traveling process of an automobile is eliminated.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a wear-resistant lateral stabilizer bushing for preventing axial movement. Background technique [0002] Automobile stabilizer bar is an auxiliary elastic element in the automobile suspension. Its function is to prevent the body from excessive lateral roll when turning, and to keep the body as balanced as possible. The stabilizer bar bushing is fixed on the vehicle frame and plays a role in supporting and positioning the stabilizer bar. At the same time, the stabilizer bar bushing must have sufficient axial stiffness to limit the axial play of the stabilizer bar. In the prior art, metal clips are used to fix the stabilizer bar and the stabilizer bar bushing, and there will be abnormal noises between the stabilizer bar and the stabilizer bar during driving, especially at low temperature due to the rubber of the stabilizer bar bushing. Hardening causes more rattling and causes...

At the same time, the stabilizer bar bushing must have sufficient axial stiffness to limit the axial play of the stabilizer bar

In the prior art, metal clips are used to fix the stabilizer bar and the stabilizer bar bushing, and there will be abnormal noises between the stabilizer bar and the stabilizer bar when the car is running, especially in low temperature conditions due to the rubber of the stabilizer bar bushing. Harder causes more rattling and causes wear on the stabilizer bar bushings, reducing service life
