Abstract
A suspension system for a vehicle includes a driving wheel support which supports for rotation a driving wheel of the vehicle, and a wheel guide which includes a plurality of arm members each of which is connected to the driving wheel support at its outer end and to the vehicle body at its inner end. The wheel guide restrains the toe angle of the driving wheel, and is arranged to cause the driving wheel to move in the direction of toe-in when a rearward load acts on the driving wheel and the driving wheel is displaced rearward. The wheel guide includes a resilient support member and a toe-out restraining member. The resilient support member resiliently supports the driving wheel support relative to the vehicle body and is arranged to contract when an external force acts thereon in a certain direction and to expand when an external force acts thereon in the reverse direction so that the driving wheel moves in the direction of toe-in when a forward driving force acts on the driving wheel. When a rearward load acts on the driving wheel while a forward driving force is acting on the driving wheel, the toe-out restraining member restrains the resilient support member from abruptly displacing the driving wheel in the direction of toe-out while permitting the resilient support member to slowly displace the driving wheel in the direction of toe-out.
