Description

Stabilizer bar bushing structure

Technical Field

The utility model relates to the technical field of automobile accessories, in particular to a stabilizer bar bushing structure.

Background

The transverse stabilizer bar is also called an anti-tilting bar and a balance bar, and is an auxiliary elastic element in an automobile suspension. The method is used for improving the rigidity of the side inclination angle of the automobile suspension and reducing the inclination angle of the automobile body. The stabilizer bar is in fact a transverse torsion bar spring, which can be functionally seen as a special elastic element. When the vehicle body only moves vertically, the suspensions at the two sides deform identically, and the transverse stabilizer bar does not work. When the automobile turns, the automobile body is inclined, the jumping of the suspensions at two sides is inconsistent, the outer suspension can press the stabilizer bar, the stabilizer bar can twist, the elasticity of the bar body can prevent the wheels from lifting, and therefore the automobile body is balanced as much as possible, and the transverse stabilizing effect is achieved. The transverse stabilizer bar is a torsion bar spring made of spring steel, is U-shaped, and is transversely arranged at the front end and the rear end of the automobile. The middle part of the rod body is hinged with the vehicle body or the vehicle frame by a rubber bushing, and the two ends of the rod body are connected with the suspension guide arm by a rubber pad or a ball pin at the end part of the side wall. The stabilizer bar bush generally has two kinds of with body of rod vulcanization integral structure and with components of a whole that can function independently structure, and vulcanization integral type can effectively solve the problem that there is relative motion between stabilizer bar body and the bush to lead to abnormal sound at stabilizer bar atress in-process to and stabilizer bar torsional rigidity reduces more problem, but the cost is higher. The cost is lower in the split type arrangement of the stabilizer bar bushing and the stabilizer bar, but the problems that the torsional rigidity is reduced more and abnormal sound is caused by the relative movement of the stabilizer bar and the bushing in the use process exist. Therefore, there is a need to invent a new stabilizer bushing structure.
