ABSTRACT:
The invention provides an improvement in an assembly comprising a frame for a motor vehicle, a pair of unsteered wheels disposed on opposite sides of the frame, and a spring suspension comprising a respective longitudinal control arm connected to each one of the wheels for constraining the wheel, each control arm having a hub, a respective bearing sleeve having one end secured to the frame and associated with a respective one of the control arms, the control arm hub being rotatably mounted in the associated bearing sleeve, the bearing sleeves having inner ends facing each other, a respective torsion bar associated with each wheel control arm for urging the control arm to a predetermined angular position about the axis of the associated bearing sleeve, the torsion bars having axes extending parallel to each other transversely to the direction of travel and the torsion bars being arranged one behind the other in this direction, and a respective anchor secured to the frame against rotation about the axis of an associated one of the torsion bars, one end of each torsion bar being fixed to the hub of the associated control arm and the other torsion bar end being fixed to the associated anchor. In the improvement, the anchors are concentrically mounted on the facing inner ends of the associated bearing sleeves and each anchor is a casting having a sprue eccentric with respect to the axis of the associated bearing sleeve, the other torsion bar ends being fixed in the eccentric sprues whereby the fixed other end of one torsion bar is offset from the fixed one end of the other torsion bar.
