Abstract
A suspension system for a motor vehicle includes a torsion member having a generally arcuate longitudinal axis. The suspension system further includes first and second control arms operatively interconnecting first and second vehicle wheels with a frame. The first and second control arms are mounted to the frame for pivotally movement. The torsion member directly connects the first and second control arms and is operative to selectively transfer torque therebetween in response to vertical displacement of the first and second wheels. When the first and second wheels are vertically displaced in unison, no torque is transferred between the control arms and the torsion member merely rotates about its generally arcuate longitudinal axis. When a difference in vertical displacement of the first and second wheels exist, for example, during cornering of the vehicle, each control arm would input opposite rotation in the torsion member, thereby generating a resisting torque.
