Abstract:

A suspension system for supporting a trailer frame on a trailer axle is provided. The suspension system includes a connector disposed about the trailer axle and upper and lower arms. The upper and lower arms are each coupled to the frame and to the connector. The upper arm is coupled to the connector at a point between the axle and the longitudinal rails of the frame. The lower arm is coupled to the connector at a point between the axle and ground. The upper and lower arms together form a Watts linkage that minimizes and/or eliminates movement of the axle in the direction of vehicle travel.
