ABSTRACT:
A hanger depending downwardly from a side of the chassis supports a torque beam and a lift spring which is mounted between a plate and the torque beam. A cross channel assembly is connected between the hangers of opposite sides of the vehicle. The forward central portion of a wishbone stabilizer assembly is connected to the center of the channel assembly by a special resilient spring and bushing assembly. The wishbone stabilizer assembly has diverging arms. The rearward end of each arm is journalled on a bushing assembly that is mounted in an axle seat assembly. Similarly, the rearward end of the torque beam is journalled on a bushing assembly that is also mounted in the axle seat assembly, and in a longitudinal direction, the stabilizer arm and the torque beam act as a parallelogram to stabilize the axle seat and maintain the pitch of the axle. An air spring is mounted between the axle seat and the chassis and is located directly above the axle. The wishbone stabilizer assembly provides a component of parallelogram stabilization and eliminates the need for a sway bar. The resulting suspension system is highly compact and free from interference with a vehicle drive shaft.
