ABSTRACT:
A clutch assembly using a ball ramp actuator supplying a clamping force on a clutch disc in response to an electromagnetic field where the clutch clamping force is maintained and increased with clutch slip using a ball ramp mechanism having a control ring and an actuation ring. A bias spring acting to maintain contact between a clutch member and the coil plate of the control clutch. Activated by a control clutch having a response to electrical current introduced into a coil thereby creating an electromagnetic field in a coil pole which attracts a coil plate which in turn applies a cone clutch thereby introducing a rotational torque on the control ring to activate the ball ramp mechanism. The bias spring is used to force the clutch plate toward the coil pole thereby minimizing the air gap between the clutch plate and coil pole thereby providing a more controllable engagement of the clutch assembly.
