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.
