ABSTRACT:
A suspension system is described which interconnects each of the longitudinally extending frame members of a truck or the like to a transversely extending axle housing positioned therebelow. Each of the suspension systems comprises a leaf spring assembly connected to the associated frame member forwardly of the axle housing. The leaf spring assembly is connected, intermediate its ends, to the axle housing. A box-like support is positioned at the rearward end of each of the leaf spring assemblies and has its forward end receiving the rearward end of the associated leaf spring assembly. The rearward end of the support has the lower end of an air spring mounted thereon. The upper end of the air spring engages a plate which extends laterally from a bracket secured to the associated frame member. The rearward end of the leaf spring assembly is pivotally secured to the upper intermediate portion of the support forwardly of the air spring. The air spring yieldably resists the upward movement of the axle housing and the rearward end of the leaf spring assembly towards the frame member and yieldably resists the downwardly movement of the frame member towards the axle housing.
