<p>A vehicle trailer frame (130) includes one or more cross member/suspension system mounting assemblies (132a, 132b) which mount axle/suspension systems (150a, 150b) and provide support against the twisting, parallelogram and S-shaped deflections typically caused by vertical, lateral, longitudinal and roll loads commonly encountered by a vehicle trailer during operation, and which can cause premature wear of trailer frame components. Each cross member/suspension system mounting assembly employs a minimal number of parts to support a single axle/suspension system, and includes a cross member (160) and a suspension assembly mounting member (161) disposed at each end of the cross member. Each suspension assembly mounting member is generally triangular-shaped and includes a horizontally-disposed base and a pair of vertically extending, diagonally opposed gussets. A plurality of openings are formed in each suspension assembly mounting member to reduce the overall weight of the cross member/suspension system mounting assembly, to accommodate an air spring mounting bolt, to facilitate welding of the mounting member to the trailer frame, and to promote drainage. Each suspension assembly mounting member fits on the cross member and is attached thereto by a continuous weld, and the mounting member and the cross member both nest in and are attached to other components of the trailer frame by continuous welds. Suspension assembly hangers are attached to the cross member/suspension system mounting assembly with continuous welds, and other components of a pair of suspension assemblies are suspended from the hangers, which in turn support an axle and wheels.</p> |
