Abstract

A rear wheel suspension system, comprising a pair of hub carriers each for rotatably supporting a wheel, a plurality of lateral links for coupling the hub carriers to a vehicle body, and a pair of shock absorbers each consisting of a spring and a linear hydraulic damper for controlling impacts which are applied to one of the wheels. The shock absorbers are arranged laterally of the vehicle body, and are each coupled between the vehicle body and one of the hub carriers by way of a bell crank mechanism which may have a progressive property. The ends of the shock absorbers on the side of the vehicle body which oppose each other may be pivotally coupled to each other by way of a coupling structure which relatively elastically attaches the opposing ends to the vehicle body but relatively rigidly supports mutually abutting axial forces from the shock absorbers. This suspension system may be attached to the vehicle body by way of a subframe, which is in turn elastically attached to the vehicle body and provided with an open channel member for accommodating the shock absorbers therein to protect them from objects thrown from the road surface.
