LEAF SPRING LIFT AXLE SUSPENSION SYSTEM ABSTRACT OF THE DISCLOSURE An upwardly biasing back-to-back, quarter-elliptic, diverging pair of leaf springs are employed as the lifting mechanism in a lift axle suspension system for wheeled vehicles. The springs normally bias the lift axle off of the road surface. By inflation of air bags, the wheels axe lowered into engagement with the road surface against the normal upward bias of the leaf springs. Release of the air automatically retracts the wheels to their riding, lift position.
