ABSTRACT:
A heavy duty suspension system for multiple axle over-the-road semi trailers. A rigid frame for the suspension includes beams on opposite sides which are connected with the trailer body. Hangers receive the front ends of spring beams to which the axles are connected. Torque arms connect the hangers with the axles. Behind the axles, air cushions are interposed between the spring beams and frame to provide an air ride. A transverse track rod is provided behind each axle to accept laterally applied loads. Each track rod is pivoted at one end to the back of one spring beam and at the other end to a track rod hanger suspended from the frame.
