ABSTRACT:
A vehicle driveline clutch 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 plurality of one-way clutches acting in a pair of planetary gearsets with a one-way clutch acting on each planet gear and supported on a carrier ring which is frictionally connected to a ball ramp control ring upon energization by a clutch control unit of an electrical coil thereby creating relative rotational motion between the control ring and an actuation ring causing a plurality of rolling elements to travel along identical opposed variable depth ramps thereby creating an axial separation force between the control ring and the actuation ring generating the clamping force on the clutch disc. Upon slippage of the clutch disc, the first and second planetary gearsets acting in concert with the one-way clutches to further energize the ball ramp actuator to increase the clutch clamping force when the vehicle is in either a drive or coast driving mode.
