ABSTRACT:
A vehicle suspension system for suspending a vehicle from an axle may be used on a steering axle and includes resilient members, such as two air springs, on opposite longitudinal sides of the axle and supported on seats suspended from the ends of a beam. The beam is connected at its center to the axle. The air springs are are connected to hangers that are mounted to the vehicle chassis. The hangers for the air springs include spaced opposed surfaces that allow a longitudinal sway guide to pass between and be transversely restrained by the surfaces. One end of the sway guide is pivotally attached to a hanger on the chassis and the other end to a shackle. The sway guide comprises a small number of spring leaves that can flex but that are not adequate for load bearing, so almost all of the chassis load is on the air springs. The assembly can be installed as original equipment or retrofit to existing equipment. The beam may be inclined to provide caster to the axle. A hose connection between the air springs can equalize air pressure therein.
