Actively controlled torsion bar suspension

摘要

A suspension system for a vehicle having a vehicle body arranged along a first axis includes a steering knuckle configured to rotatably support the vehicle's road wheel. The system also includes a torsion bar that is configured to generate a spring rate and arranged along a second axis that forms an acute angle relative to the first axis. The system also includes a tensile drop link fixed relative to the steering knuckle. The system additionally includes a semi-trailing arm having a first end and a distal second end, wherein the semi-trailing arm is operatively connected to a first end of the torsion bar at the first end of the arm and to the tensile drop link at the second end of the arm. Furthermore, the system includes an actuator fixed relative to the body and configured to rotate a second end of the torsion bar about the second axis.
