ABSTRACT:
A suspension system for controlling the relative displacement between a pair of laterally opposed ground engaging components of a vehicle and the frame of the vehicle is described herein. Each of the ground engaging components is individually mounted to the frame by a frame connecting component. The frame connecting component is hingedly mounted to the frame so as to allow a relative pivotal movement between each of the frame connecting components and the frame in a direction substantially parallel to the longitudinal axis of the frame. The suspension system includes a first suspension member pivotally mounted to the frame. The first suspension member is free to pivot relatively to the frame about a first suspension member pivotal axis that is in a substantially transversal relationship with the frame. The suspension system also includes a second suspension member pivotally mounted to the first suspension member so as to allow the first suspension member and the second suspension member to pivot relatively to one another along a second suspension member pivotal axis that is in a substantially perpendicular relationship with the first suspension member pivotal axis. The suspension system further includes a biasing mechanism mounted both to the frame and to the second suspension member. The biasing mechanism bias the second suspension member towards a second suspension member initial predetermined position. A pair of motion transmitting members are respectively mounted to one of the frame connecting components and to the second suspension member.
