Title: TRAILING ARM SUSPENSION
Abstract:
A trailing arm suspension (10, 210, 310, 410) comprising a trailing arm (20, 220, 320, 420) having one portion pivotally connected to a frame bracket (22) extending from a vehicle frame (16) and another portion connected to the vehicle frame by an air spring (26) for resisting the rotational forces of the trailing arm. The trailing arm preferably comprises opposing side plates (56, 58) connected by multiple sleeves (94), which are preferably the inner sleeves of bushed connectors (24, 30, 36, 38). Mechanical fasteners (92) extend through the sleeves to compressively mount the side plates to the sleeves to form a rigid beam. An axle adapter (28) and a torque tube adapter (34) are also positioned between the opposing plates. Each of the frame bracket, axle adapter, and torque tube adapter are connected to the trailing arm side plates through a bushed connector to permit the articulation of the trailing arm and whose inner sleeve is used to connect the side plates.
