Abstract
The present disclosure provides a sway bar for a suspension system of a motor vehicle. The sway bar includes a first lever arm for attachment to a left wheel suspension component and a second lever arm for attachment to a right wheel suspension component. The sway bar further includes a torsion spring device in connection between the first lever arm and the second lever arm to provide variable torsional stiffness. The torsion spring device includes a first torsion bar, a second torsion bar, and a clutch connected to the first torsion bar and the second torsion bar. The clutch is configured to move between a disengaged position and an engaged position where both of the first and second torsion bars transmit torque between the first and second lever arms to provide torsional stiffness.
