A vehicle trailer frame includes one or more cross member/suspension system mounting assemblies which mount axle/suspension systems 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 and a suspension assembly mounting member 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.

[ What is claimed is:] [1.]1. A vehicle trailer frame, said frame including:a) a pair of elongated spaced-apart parallel main members; andb) at least one cross member/suspension system mounting assembly, said assembly including:i) a cross member having a pair of ends, said cross member extending between said main members, and each of said cross member ends being attached to a respective one of said main members; andii) a pair of suspension assembly mounting members, each of said mounting members being attached to a respective one of said cross member ends and a respective one of said main members, each of the mounting members being generally triangular-shaped and including a horizontally-disposed, generally triangular-shaped base and a pair of spaced-apart, vertically extending and diagonally opposed gussets, said gussets each extending vertically a substantial distance relative to the height of its respective main member, so that an axle/suspension system can be mounted on and depend from said cross member/suspension system mounting assembly, whereby the frame is prevented from significantly deflecting from an unchanged shape to a changed shape.
