摘要： A suspension system includes a swing arm which pivots about a pivot axis. A hub assembly, hub gear box and input gear box are mounted to an independently pivoting swing arm. The pivot axis is located closer to the ground than a rotational axis defined by the hub assemblies and the input gear box. A coupling extends from the input gear box to receive an input driveline from a drive source such as vehicle engine. The coupling is located proximate the pivot axis to minimize relative movement during articulation of the swing arm. An axle housing extends between the input gear box and an opposite hub gear box to support a drive shaft and serves as a torsion bar.

摘要： A torsion bar suspension assembly is provided that includes a control arm supported by a frame. The torsion bar extends along a longitudinal axis having a first end portion connected to the control arm and a second end portion engaging the frame. A contact arm is connected to the torsion bar and is arranged between the first and second end portions. The contact arm is spaced from the frame in a first position and engages the frame in a second position. A first spring rate is provided when the contact arm is spaced from the frame between the first and second positions. Once the contact arm engages the frame between second and third positions, a second spring rate is provided that is different from the first spring rate.
