ABSTRACT:
A suspension assembly comprising a combination torque rod and sway bar is shown and described. In a preferred embodiment, the assembly comprises two arms that are pivotally coupled at a first end to a first and second end of a crossmember, the second ends of the arms being coupled to a vehicle axle. By providing a suspension assembly in this manner, the arms function as torque rods to absorb the longitudinal stresses generated by the acceleration and deceleration of the vehicle. The arms also work in combination with the crossmember to function as a sway bar, the pivotal coupling between the arms and crossmember allowing the assembly to transfer vertical forces from one side to the other, while still allowing the axle to cross-articulate. In this manner, the number of components, weight, and cost of manufacture is minimized, traction is improved, and component fatigue and failure is minimized.
