Abstract
The present disclosure provides a suspension system for a vehicle that includes a primary load bearing system and a secondary load bearing system. The primary load bearing system is disposed between a frame and an axle of the vehicle, and is continually loaded. The secondary load bearing system is also disposed between the frame and the axle of the vehicle, but the secondary load bearing system is operable between a loaded condition and an unloaded condition. During the loaded condition, the secondary load bearing system is contacted by an engaging member attached to the frame such that a load carried by the vehicle is supported by the primary load bearing system and the secondary load bearing system. During the unloaded condition, the secondary load bearing system is isolated from the frame and the axle.
