Abstract
A suspension assembly for a vehicle including an elongated central torsion axle shaft of a rubber torsion axle assembly, a torsion axle shaft pivot point about which the torsion axle shaft pivots, a spring and an elongated spindle swing arm. The spring has a first end and a second end and the first end of the spring is connected to a fixed point relative to a vehicle frame. The spindle swing arm has a second end with the first end connected to the torsion axle shaft with the second end of the spindle swing arm connected to the second end of the spring. The spring can set the torsion axle shaft to a predetermined position, such as at or near a no-load position, when only static forces are present. This provides for a torsion axle with a greater range of movement and significantly improves its lifespan.
