Abstract
A dynamically variable roll stabilizer for a motor vehicle including a split U-shaped torsion bar on a body of the motor vehicle, a pair of rigid links between opposite ends the torsion bar and respective ones of a pair of suspension control arms of the motor vehicle, a mechanical coupling between the two separate elements of the torsion bar, and an electromagnetic actuator. The coupling includes a pair of oppositely acting roller clutches between the two separate elements of the split torsion bar. The electromagnetic actuator includes a pair of control rings which engage and disengage the roller clutches, a pair of control levers on the control rings, and an electric solenoid suspended between the control levers. When the solenoid is on, the control levers are thrust together and the control rings disengage the roller clutches. When the solenoid is off, the control levers are thrust apart by a spring and the control rings engage the roller clutches. The effective torsion modulus of the torsion bar is maximum when the roller clutches are engaged and zero when the roller clutches are disengaged.
