Abstract
A transmission clutch module includes first and second races, and a plurality of race engagement mechanisms situated between the races. The module incorporates an integrated hydraulic actuator having an actuator cam ring that includes cam ramps configured for moving the race engagement mechanisms between positions adapted to selectively interact with the races. As such, the actuator, designed to be contained entirely within a generally circumferential envelope of the clutch module, may control rotation of the actuator cam ring between at least two spaced angular positions in at least one embodiment. In various other embodiments within the scope of this disclosure, the actuator cam ring may be adapted to rotate among any number of pre-determined positions to operatively permit or prevent the transmittal of torque between the first and second races.
