ABSTRACT:
A lightweight trailing arm suspension comprises a frame bracket assembly (18), a trailing arm (16) and an air spring assembly (22) formed of a fixed cup (64) with a movable piston (66) mounted in lateral juxtaposed relationship to a terminal end of the trailing arm assembly (56). A clamping assembly (28) affixes the trailing arm to the axle (24), thus suspending the ground engaging wheels (14). A wear pad (60) interposed between a portion of the clamping assembly (28) and the trailing arm (16) resists the torsional moment of the trailing arm to provide stability and minimize wear. The cup (64) is hollow and communicates with the interior of an air spring (72) to provide a reservoir therefor. A track bar (115) with bushed joints at both ends interconnects the frame (10) and the axle housing (26) to provide lateral stability.
