Abstract

A stabilizer bush including: a tubular rubber bushing body having an inner hole for inserting a stabilizer bar; and a mounting base provided on a fixing surface of the rubber bushing body against a vehicle body. The stabilizer bush is configured to be installed on the vehicle body such that an outer peripheral surface of the rubber bushing body is press-fitted on a side of the vehicle body via the mounting base by a roughly U-shaped bracket to be fixed to the vehicle body. The rubber bushing body includes a shock absorbing rubber part that is elastically deformed due to a compression force caused by pressing of the bracket, bulges to both sides in the width direction of the mounting base, and enters and interposes between the mounting base and the bracket.

First claim

What is claimed is:

1. A stabilizer bush comprising:
a tubular rubber bushing body having an inner hole for inserting a stabilizer bar; and
a mounting base provided on a fixing surface of the rubber bushing body against a vehicle body;
wherein the stabilizer bush is configured to be installed on the vehicle body such that an outer peripheral surface of the rubber bushing body is press-fitted on a side of the vehicle body via the mounting base by a roughly U-shaped bracket to be fixed to the vehicle body,
wherein the rubber bushing body includes a shock absorbing rubber part that is elastically deformed due to a compression force caused by pressing of the bracket, bulges to both sides in a width direction of the mounting base, and enters and interposes between the mounting base and the bracket, and
wherein the stabilizer bush comprises a locking portion inserted through a central concave portion of the mounting base, the locking portion provided for maintaining an assembled state of the mounting base and the rubber bushing body by preventing mutual detachment.

2. The stabilizer bush according to claim 1 , wherein the mounting base has a width dimension A at a side of overlapping with the rubber bushing body, and with respect to the width dimension A, a maximum width dimension B of the rubber bushing body is set as A ≤B in a state where there is no external force on the rubber bushing body.

3. The stabilizer bush according to claim 1 , further comprising concave-convex interlocking portions provided between overlapping surfaces of the mounting base and the rubber bushing body, the concave-convex interlocking portions extending in a width direction on both side portions in a length direction of the rubber bushing body.

4. The stabilizer bush according to claim 1 , wherein on an overlapping surface of the mounting base against the rubber bushing body, curved corner sections are formed by R-chamfering corners at both side edge portions in the width direction.

5. The stabilizer bush according to claim 1 , wherein the shock absorbing rubber part extends from an outer surface of a shoulder portion of the mounting base and is configured to reach a gap between the mounting base and the bracket.

6. The stabilizer bush according to claim 5 , wherein an extension dimension of the shock absorbing rubber part is set in a size from 0.5 mm to 2.5 mm.
