A rear suspension apparatus for a motor vehicle having a differential gear case ( ) disposed between rear right- and left-wheels ( R, L), which is of a torsion beam type. In the rear suspension apparatus, a central portion ( ) of a torsion beam ( ) for rotatably supporting the rear right- and left-hand wheels ( R, L) is curved to run along the configuration of the differential gear case ( ), and is disposed at the rear of the differential gear case ( ). A suspension damper ( ) stretched between the torsion beam ( ) and the vehicle body is disposed to be inclined upwardly and forwardly.

Rear suspension apparatus for motor vehicle

An intersection of an extension of a front lower arm with an extension of a rear lower arm outside a transversely outer side constitutes a lower set point of a virtual kingpin axis. The transversely inner end portion of one lower arm of the front lower arm and the rear lower arm is connected to the body of the vehicle so as to be capable of being displaced in the longitudinal direction of the body. When the wheel is steered, the transversely outer end portion of the lower arm for the externally cornering wheel is displaced rearward while it pivots rearward about the transversely inner end portion of the lower arm, and the rearward displacement is transmitted so as to displace the transversely inner end portion of the one lower arm through a control link. The control link may be divided into two elements.

Suspension apparatus for an automotive vehicle

A front wheel suspension comprising left and right suspension arm disposed front side frames and steering knuckles of a car body and a stabilizer bar of which outer bar ends bent forth are fastened to outer sides of the left and right suspension arms so as to allow left and right wheel independently to move up and down. The left and right suspension arms are pivoted to gussets each of which is fastened to the side frame member and a reinforcement member so as to form at its rear end a space between the side frame and reinforcement members. The stabilizer bar extends transversely over the upper surface of the gusset through the space.
