Abstract
An axle suspension system for a wheeled vehicle is disclosed. The system includes a frame, a frame connection member, a beam assembly, a torque box and an air bag connection. The beam assembly is lightweight, cost effective, and efficient because the beam assembly utilizes a box beam structure in conjunction with the torque box structure which provides for substantially even distribution of axle deflections throughout the entire beam assembly.

- a beam having a resilient pivotal bushing said bushing being attached at one end of said beam to a hanger bracket and a spring means attached at the other end of said beam opposite said bushing thereof, wherein said beam extends longitudinally along said vehicle and includes a substantially U-shaped first member with two opposing sides integrally formed with a cross-member, and at least one second member rigidly attached to said U-shaped first member and being of such a shape and so located, such that said second member is spaced away from said cross-member, thus to define a portion of an axle locus;
- and
- said second member comprising;
- a longitudinally extending plate means having a first and a second end said second end forming one side of said axle locus and a third end intermediate said first and second ends to form a second side of said axle locus, said first, second and third ends being integrally connected by said plate means such that said plate means spans and connects at least a portion of the opposing sides of said U-shaped first member.
