Abstract
A suspension for a motor vehicle comprises a control arm connected to each of a pair of wheels, a torsion bar, and a height actuator. The torsion bar is connected to each control arm, and is rotatable in first and second directions. The height actuator is connected between the torsion bars, and is operable to lower a sprung mass of the vehicle by rotating the torsion bars in the first directions, and to raise the sprung mass by rotating the torsion bars in the second directions. A roll actuator is also connected between the height actuator and the sprung mass.
