Rear wheel suspension arrangement for motor vehicles

摘要

A rear wheel suspension arrangement of trailing arm type for motor vehicles includes a trailing arm for supporting a rear wheel, and a pair of upper and lower lateral arms. The trailing arm is split into a vehicle body side arm and a wheel side arm, which are coupled to have a degree of displacing freedoms within a horizontal plane of the vehicle body. The vehicle body side arm is formed shorter than the lateral arms, whose pivotally securing portion to the vehicle body is disposed at the front side from the coupling portion to the wheel side arm, and disposed in the inside in the lateral direction from the wheel side arm. The lower lateral arm is pivotally secured at least to the wheel side arm via a ball joint.
