Problems solved by technology

Therefore, it is difficult to install the bushing contact surface of the stopper member parallel to the end surface of the vibration-proof bushing
For example, even if the spring characteristics of the anti-vibration bushing when the end face of the anti-vibration bush abuts against the bushing contact surface of the stopper member are set, depending on the mounting state of the stopper member, the end face of the anti-vibration bushing and the stopper member may be different. When one end of the bushing contact surface of the movable member contacts and the spring characteristic of the intended anti-vibration bushing cannot be exerted

Abstract

Disclosed is a suspension arm attachment structure provided with a cylindrical vibration-damping bush which is attached to the side of a vehicle body via a core member. Specifically disclosed is an attachment structure provided with: a suspension arm (14) which has an attachment tube part (41) fitted with a vibration-damping bush (52); and a retaining member (46) which regulates the movement of the attachment tube part (41) in the axial longitudinal direction. The retaining member (46) is provided with: a facing wall (71) on one side and a facing wall (72) on the other side which respectively face end surfaces (64, 65) of the vibration-damping bush (52); a linking part (73) which integrally links the facing wall (71) on one side and the facing wall (72) on the other side; and an attachment part (74) on one end and an attachment part (75) on the other end which respectively extend in the axial longitudinal direction of a core member (51) from the facing surface (71) on one side and the facing surface (72) on the other side and which are attached to the side of a vehicle body (11).

Description

Technical field [0001] The present invention relates to a suspension arm mounting structure provided with a cylindrical anti-vibration bush, which is fitted into an installation tube portion of the suspension arm and is mounted on the vehicle body side via a core member. Background technique [0002] This type of suspension arm mounting structure adopts the following structure: a mounting cylinder is formed at the end of the suspension arm (lower arm), a vibration-proof bushing is fitted into the mounting cylinder, and the shaft of the vibration-proof bushing is formed Both ends of the core member are mounted to suspension elements formed on the vehicle body side. Both ends of the core member are respectively mounted on the suspension element via bolts of different body stop members. [0003] According to the above-mentioned suspension arm mounting structure, when an excessive input is applied to the suspension arm from the wheel side, the stopper member is used to prevent the mou...
