12. An system for controlling the roll of a motor vehicle, the system including first and second electrically operated actuators, wherein the first actuator is connected at the front of the vehicle between an unsprung portion of the vehicle and a sprung portion of the vehicle for selectively coupling the sprung portion of the vehicle to the unsprung portion of the vehicle, and wherein the second actuator is connected at the rear of the vehicle between the unsprung portion of the vehicle and the sprung portion of the vehicle for selectively coupling the sprung portion of the vehicle to the unsprung portion of the vehicle, each actuator comprising:
-
a collet finger mounted to one of the sprung portion of the vehicle and the unsprung portion of the vehicle;
a grooved input rod mounted to the other of the sprung portion of the vehicle and the unsprung portion of the vehicle; and
a collet engagement mechanism for selectively moving said collet finger into and out of engagement with the grooves of said input rod. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
