Problems solved by technology

However, due to torsional input or the like applied to the stabilizer bar 200, sliding tends to occur at the contact interface of the rubber outer peripheral surface of the elastic body 210 and the bracket 214, and this sliding generates abnormal noise such as a rattling noise.

Embodiment Construction

[0042] Referring first to FIGS. 1A and 1B , there is shown a stabilizer bar 10 consisting of a metal rod having a generally portal-shaped planar configuration and a central portion 10a thereof. That is, the stabilizer bar 10 is substantially straight in the vehicle width direction (vehicle lateral direction) and is fixed to the vehicle body via the stabilizer bushing 12 with the arms 10b at both ends thereof fixed at their ends for on the suspension arm that supports the wheel.

[0043] In FIGS. 2 and 3 , the specific configuration of the stabilizer bushing 12 mounted to the stabilizer bar 10 and the stabilizer bar 10 itself are shown in detail. As apparent from the drawings, the stabilizer bush 12 of the present embodiment has a rigid bracket 14 made of metal, a rubber elastic body 16 , and a rigid intermediate plate 18 made of metal embedded in the rubber elastic body 16 .

[0044] The rubber elastic body 16 is cylindrical in cross section, and has an annular through hole 2...

Abstract

The invention relates to a stabilizer bar bushing (12), comprising a rubber elastic body (16); a bracket (14) and a middle part embedded in the rubber elastic body along the axis vertical direction so as to extend substantially the entire axial direction of the rubber elastic body An intermediate plate (18) extending in length, whereby the rubber elastic body is divided by the intermediate plate into an inner rubber layer (16-1) and an outer rubber layer (16-2) with a spring constant smaller than the inner rubber layer. The stabilizer bar bushing is composed of two circumferential divisions (12A, 12A), wherein the bracket and the middle plate are integrally vulcanized with the divisions, and the divisions are assembled together to clamp the stabilizer bar along the vertical direction of the axis ( 10) and withstand the compression along the vertical direction of the axis, so that the inner surface of the through hole (20) is bonded to the outer peripheral surface of the stabilizer bar through the adhesive (S).

Description

[0001] References [0002] The contents of Japanese Patent Application No. 2004-316866 filed on October 29, 2004 including specification, drawings and abstract are hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a stabilizer bushing for elastically mounting a stabilizer bar on a vehicle body (body) of a motor vehicle. Background technique [0004] Stabilizer bars are torsionally rigid springs (torsion bars) mounted on the car body to reduce lean. The stabilizer bar is mounted on the left and right suspensions via its ends, and serves to suppress different vertical movements of the left and right wheels. For example, when the vehicle is cornering, the outer suspension is compressed and the inner suspension is extended due to the centrifugal force, so that the vehicle body tends to lean toward the outside due to the centrifugal force. When the left and right wheels move vertically in antiphase (i.e., during roll), the sway ...
