Patent ID: 7201265

Claim:
A torque transfer mechanism, comprising: a first rotary member; a second rotary member; a friction clutch operably disposed between said first and second rotary members; a clutch actuator operable to adaptively regulate engagement of said friction clutch and including an operator mechanism and a drive mechanism, said operator mechanism including first and second actuator plates rotatably supported on said first rotary member, a cam arrangement operable for causing axial movement of said second actuator plate relative to said friction clutch in response to relative rotation between said first and second actuator plates, and a linear operator including a piston assembly having a roller engaging a cam surface formed on an arm segment extending from one of said first and second actuator plates, said drive mechanism including a power-operated device operable for controlling movement of said linear operator for causing relative rotation between said first and second actuator plates; and; a control system for controlling actuation of said power-operated device.
