ABSTRACT:
An air suspension system for a wheeled vehicle and particularly for the auxiliary lift axle of a vehicle wherein a trailing arm supporting the axle is pivotably supported at one end to the frame with an air spring operatively connected to the other end of the arm and a cantilever leaf spring rigidly connected at one end to the arm and cooperating with a frame-supported link at its other end to form a mechanism which normally biases the axle to an elevated position and which, in the lowered position of the axle, serves both as an energy store for lifting the axle and as a means of shock absorption.
