Abstract
A clutch apparatus includes a torque cam mechanism and a clutch actuator for compressing a clutch disc pack for clutch engagement through the torque cam mechanism. The clutch actuator includes a first fluid chamber for pushing the torque cam mechanism from a first position for all-time clutch disengagement, to a second position toward the clutch disc pack, and a second fluid chamber for pushing the torque cam mechanism from the second position to a third position for all-time clutch engagement toward the clutch disc pack. At the second position, the torque cam mechanism functions as a one-way clutch by extending axially in response to relative rotation between both sides in one rotational direction.
