  "textContent": "A trailing arm (14) is provided for a vehicle suspension (10) including a forward portion (28). The forward portion extends longitudinally to a rearward portion (30) with the trailing arm having at least a portion with an open bottom (31). The trailing arm preferably has a generally U-shaped cross-section over a substantial portion of its length. A bushing assembly (34) is secured to the forward portion defining a first pivotal connection by which the trailing arm is secured to the frame. An air spring support plate (56) is secured to the rearward portion opposite the open bottom. Preferably, the trailing arm tapers inwardly from the rearward portion to the forward portion to provide increased structural rigidity in the area of the trailing arm that supports the axle and other suspension components. The trailing arm is formed of a sheet of metal to provide the generally U-shaped cross-section. The bushing assembly is welded to one end portion of trailing arm to define the first pivotal connection, and an axle attachment member is welded to another portion of the trailing arm. Brackets and plates for supporting suspension components such as air springs (18), an anti-roll bar (22), and shock absorbers may be welded to the trailing arm.",
