Vehicle stabilizer bushing

Abstract

Disclosed is a stabilizer bushing which more efficiently reduces torsional friction between a bushing main body and a stabilizer bar. A bushing main body (16) is formed from a cylindrical rubber elastic body to which a sliding member (42) is fixed to a surface of the inner circumference. In a middle area of the bushing main body (16) perpendicular to the axis thereof, two partition members (26, 26) are embedded so as to be positioned vertically, and are adhered by vulcanization. The bushing main body (16) is constituted from an inner rubber part (38) of a thickness so as not to allow elastic deformation by an input load, and an outer rubber part (40) thicker than said inner rubber part. Meanwhile, through-holes (36a, 36b and 36c) are formed only in positions that equally divide the partition members (26, 26) in the circumferential and axial directions.

Description

technical field [0001] The present invention relates to a stabilizer bush for a vehicle, in particular to an improved structure of a stabilizer bush for a vehicle in which a stabilizer bar is inserted into an inner hole in a non-adhesive state so that the stabilizer bar elastically supports the vehicle body . Background technique [0002] As is well known, vehicles such as automobiles are equipped with stabilizer bars for suppressing tilting of the vehicle body when cornering or the like. The stabilizer bar is generally mounted on the vehicle body via a stabilizer bush (vibration-isolating bush) on the outer peripheral surface of a bushing body made of a cylindrical rubber elastic body having an inner hole through which the stabilizer bar penetrates. The bushing is fitted with a rigid bracket mounted on the body. [0003] However, it is well known that with regard to a stabilizer bush for mounting a stabilizer bar on a vehicle body, when the stabilizer bar is rotated in a ...

AI Technical Summary

Problems solved by technology

Therefore, in such a stabilizer bushing, when a vertical load is input to the stabilizer bushing in the state where the stabilizer bushing is mounted on the vehicle when the sliding member is made of lining cloth, the bushing will Both the outer rubber part and the inner rubber part of the main body are elastically deformed, thereby causing warping and wrinkles in the interlining fixed to the inner peripheral surface of the inner rubber part.

Also in this case, the sliding performance with respect to the stabilizer bar in the circumferential direction of the backing cloth is also uneven, thereby possibly hindering the smooth rotation of the stabilizer bar in the torsional direction.
