Back suspension device

Abstract

The present invention provides a rear suspension device comprising a wheel support equipment for freely rotatablely supporting a wheel, a suspension trailing arm which extends in the front and rear directions of a vehicle and has a rear end mounted to said wheel support equipment and a front end freely rotatablely mounted to a vehicle body so as to be swingable formed to allow an outer-obliquity angle change of the wheel, a lateral link which one end is freely rotatablely mounted to said wheel support equipment and the other end is freely rotatablely mounted to a vehicle body, a plurality of fastening parts for fastening the trailing arm to the wheel support, a lateral link mounting part formed on a wall surface which forms an opening of a place surrounded by the plurality of the fasteningparts of the wheel support. Thus, it is possible to surely support a lateral link while securing an excellent package placement property without forming a bracket for mounting an additional link in arear suspension device.

Description

technical field [0001] The invention relates to a rear suspension device of a vehicle. Background technique [0002] The known vehicle rear suspension device in the past includes a suspension extending along the front and rear direction of the vehicle, one end is mounted on the wheel support device, and the other end is mounted on the vehicle body freely, and the camber angle (camber angle) of the wheel is allowed to change. trailing arm. [0003] Such a rear suspension device, as shown in Japanese Patent Laid-Open Publication No. 2003-112508, includes a swing arm (suspension trailing arm) made of a stamped and formed steel plate. The front end part of the vehicle body is used to connect the rear wheel support member to the rear part of the vehicle body, and the shock absorber support member is attached to the lower part of the vehicle body. The rear suspension allows the camber angle of the wheel to vary by moderately bending the stamped swing arm. [0004] However, in t...

Problems solved by technology

[0004] However, in the above-mentioned conventional rear suspension device, the swing arm (suspension trailing arm) is a press-formed part integrally formed with the rear wheel support member (wheel support device), so the rigidity is generally low. The other end of the lateral link (lateral link) that extends in the width direction of the vehicle body and is installed on the vehicle body freely at one end requires additional reinforcement brackets or reinforcement of the mounting portion, which deteriorates the performance of component installation
