Abstract: A suspension system for a vehicle having a frame and a rear axle for wheels. The suspension system includes a pair of trailing arms, each trailing arm extending from the frame and connected to the rear axle. A pair of torque rods, each has a first end pivotally extending from the tractor frame and a second end. A stabilizer plate has a first end connected to the frame and a pair of second ends. A fifth wheel mounting bracket pivotally connects each torque rod second end and pivotally connected to the stabilizing plate second ends. A load mechanism extends between the trailing arms and the mounting bracket to raise or lower the fifth wheel mounting bracket while remaining parallel.

Abstract: The vehicle suspension provides an axle assembly which may be mounted either on a truck-tractor or a truck-trailer to provide an additional axle. The suspension includes an axle which is suspended from a vehicle frame by means of a spring structure. A drawbar extends forwardly from the axle to connect the axle to the vehicle frame. A lifting mechanism is provided to raise the axle and associated wheels off the ground when desired.
