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 disclosed herein. Each of the ground engaging components is individually fixed 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. The suspension system includes a first suspension member pivotally mounted to the frame to pivot about a first suspension member pivotal axis. The suspension system also including a second suspension member pivotally mounted to the first suspension member to pivot relatively to the first suspension member about along a second suspension member pivotal axis perpendicular to the first suspension member pivotal axis. lThe suspension system further includes a biasing mechanism mounted both to the frame and to the second suspension member. The biasing mechanism biases the second suspension member towards a second suspension member initial predetermined position.
