Abstract
A driveline master clutch assembly is disclosed where a unidirectional ball ramp mechanism is used to apply a clamping load to a clutch pack for frictionally coupling a prime mover such as an engine to a gear change transmission. The ball ramp mechanism includes index plates to limit the rotation of a control ring and an activation ring such that the energized ball ramp mechanism increases in separation distance to increase the clamping force on the clutch pack whenever there is slippage in the clutch pack irregardless of the direction of torque flow through the master clutch assembly.
