ACTIVELY CONTROLLED TORSION BAR SUSPENSION
First Claim
1. A vehicle comprising:
- a vehicle body arranged along a first axis;
a road wheel configured to maintain contact with a road surface; and
a vehicle suspension corner connecting the road wheel to the vehicle body and configured to maintain contact between the road wheel and the road surface, the vehicle suspension corner including;
a steering knuckle configured to rotatably support the road wheel;
a torsion bar having a first bar end and a distal second bar end, wherein the torsion bar is configured to generate a spring rate and is arranged along a second axis that forms an acute angle with respect to the first axis; and
a tensile drop link fixed relative to the steering knuckle;
a semi-trailing arm having a first arm end and a distal second arm end, wherein the semi-trailing arm is operatively connected to the first bar end at the first arm end and to the tensile drop link at the second arm end; and
an actuator fixed relative to the vehicle body and configured to rotate the second bar end about the second axis.

Abstract
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.
