ABSTRACT:
A suspension system has a lower torque rod with a forward end pivotally connected to a hanger and a rearward end pivotally connected to an axle seat assembly. An upper torque rod has a forward end pivotally connected to the chassis intermediate the sides thereof and a rearward end pivotally connected to the axle. Forward and rearward air springs are mounted between the axle seat assembly and the chassis fore and aft of the axle. The upper torque rod functions as the upper arm of a parallelogram and as a lateral stabilizer bar. The upper torque rod and a like torque rod on the opposite side of the vehicle cooperate with the axle to define an A-frame, but the connection of the upper torque rod to the chassis is independent of said opposite torque rod.
