Abstract
A suspension system having a torque beam pivotally connected to a bushing supported by a hanger and an axle seat having a linear bushing mount to the torque beam to provide a universal pivot at the axle seat. In one embodiment there is another bushing between the torque rod and the axle seat so that the entire universal pivot is at the axle seat. In another embodiment, the universal pivot is provided partly by the torque rod connection to the hanger and partly by the connection between the axle seat and the torque rod. In two other embodiments, identical components allow installation of a suspension system to a tag axle or a steer axle except that a special tower is provided for the steer axle installation to give clearance between the vehicle frame and the wheel. Two additional embodiments have an overslung axle seat and in one, the torque beam and axle seat are outboard of the chassis.
