Abstract
A suspension system having a torque beam with a bushing for connecting the torque beams to a hanger. The torque beam can be telescopingly received in a sleeve of an axle seat assembly. There are a number of different axle seat assemblies for accommodating various vehicles but all have the sleeve so that one form of torque beam can be used with any one of the axle seat assemblies. The bushing has strategically located recesses to facilitate flow of the bushing member and to make it more yieldable in a vertical direction than in a longitudinal direction. An annular groove in the outer wall of the bushing also improves flow under compression of the bushing member. The telescoping connection between the torque beam and an axle seat assembly may include knock-away components to facilitate breaking the components apart in the event they become rusted together.
