Patent ID: 7189182

Claim:
A power transmission comprising: a rotary input member adapted to receive drive torque from a source of torque; a rotary output member; and a torque transmitting mechanism selectively operable to transfer drive torque between said input member and said output member, said torque transmitting mechanism including: a selectively operable one-way clutch including a rotatable member for switching said one-way clutch between a released mode and a locked mode; a friction clutch operable to transmit torque to said rotatable member and control the mode of operation of said one-way clutch; an actuator operable to apply a clutch engagement force to said friction clutch, wherein said friction clutch includes a first clutch plate fixed for rotation with said input member and a second clutch plate fixed for rotation with said rotatable member; and a second torque transmitting mechanism selectively operable to operatively couple said output member to a non-rotatable member for braking rotation of said output member.
