Abstract
A suspension assembly is provided for positioning a wheel support axle below the frame of a vehicle. The assembly comprises a support bracket extending downwardly from a vehicle frame, with a trailing arm pivotally mounted to said bracket and extending therefrom to the axle. The trailing arm is secured to the axle by means of a top, U-shaped clamping member mounted over the trailing arm and having side legs with recessed portions adapted to snuggly mate with the axle and a bottom plate adapted to fit snuggly within the U-shaped clamping member between the side legs and being located between the trailing arm and the U-shaped clamping bracket. A pin projects from a surface of the trailing arm and mates with a hole in the top, U-shaped clamping member or the bottom plate to hold the axle and trailing arm assembly against relative movement in a direction generally along the longitudinal axis of the trailing arm. Welds secure the U-shaped clamping member sides legs to the bottom plate and welds securing the U-shaped clamping member side legs to the axle. An air spring is mounted between the axle and frame.
