Problems solved by technology

When such a gap x occurs between the end surface of the cylindrical holding portion 212 and the flange 208, it causes a problem that, since the holding force of the cylindrical holding portion 212 formed by press working is weak, the When an axial force is applied to the anti-vibration bushing 200, the anti-vibration bushing 200 is easily axially displaced relative to the cylindrical holding portion 212.

Embodiment Construction

[0046] Hereinafter, preferred embodiments of the present invention in a suspension bushing assembly will be described in detail with reference to the accompanying drawings. figure 1 A suspension arm 10 is shown as a counterpart part for connecting the vehicle body and the wheel - these are called so-called A-arms. exist figure 1 Among them, the bottom end of the suspension arm 10 is connected to the wheel side, and the top end is connected to a shaft 12 fixed to the vehicle body. An anti-vibration bush 14 is provided in a portion connecting the suspension arm 10 and the shaft 12 . This component is specifically in figure 2 shown in .

[0047] Such as figure 2 As shown in , the anti-vibration bushing 14 has a metal outer cylinder member (rigid outer cylinder member) 16 and a metal inner cylinder member (rigid inner cylinder member) 18 disposed inside, and the outer cylinder member 16 and the inner cylinder member 18 Cylindrical rubber elastic bodies 20 are interposed s...

Abstract

The invention discloses an anti-vibration bushing assembly, wherein the anti-vibration bushing (14) is axially press-fitted to a rigid cylindrical retainer ( 34) in order to assemble it together. A rigid spacer band (42) in the form of a ring continuous in the circumferential direction and integrally a belt is mounted on the peripheral surface of the outer cylinder member in a state of external fit with axial pressure. The flange of the outer cylindrical part and the end face of the cylindrical holding part are axially contacted by the spacer ring band, and the spacer ring band partially has at least one protruding protrusion (44) on the inner peripheral surface, so as to Fit and fix to the outer cylinder part. The invention also discloses an anti-vibration bushing and a rigid spacer band for the assembly.

Description

[0001] quote reference [0002] The disclosure of Japanese Patent Application No. 2004-338062 filed on November 22, 2004 - including specification, drawings and abstract - is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to an anti-vibration bush including a rubber elastic body interposed between a rigid outer cylinder part and an inner cylinder part, and a method for fitting, mounting and fixing the anti-vibration bush to a counterpart part Anti-vibration bushing assembly on rigid cylindrical mount. Background technique [0004] Generally, a vibration-proof bush having a rubber elastic body interposed between a rigid outer cylinder member and an inner cylinder member has been widely used as a suspension bush or the like that elastically couples a vehicle body and a suspension arm , the outer cylinder part has a radially outward flange at an axial end, and the inner cylinder part is disposed inside. Such anti-vibra...
