Abstract
A torque beam assembly is provided with a bushing clamp assembly at one end and an axle seat assembly at a second end that reduce the torsional stress exerted on the torque beam during normal suspension operation of a vehicle employing the torque beam assembly. The bushing clamp is formed as a cylinder having a slot through one side of the cylinder wall that is resiliently biased open to facilitate the insertion of a pivot bushing into the cylinder and the removal of the bushing from the cylinder. The pivot bushing is provided with troughs in its end walls and cavities that extend into the bushing from the troughs that together reduce torsional twisting stress exerted on the torque beam. The axle seat assembly is provided with inboard and outboard side plates that each have first ends connected to the torque beam and second ends that are flared outward and spaced further apart from each other than are the first ends. The second ends of the side plates are connected to the vehicle axle by either welds or U-bolt connections. The flared portions of the inboard and outboard side plates enable flexing of the axle seat assembly and reduce the torsional stress exerted on the torque beam i…
