  • Electrohydraulic torque transfer device with integrated clutch and actuator unit
    Patent number: 7993232
    Abstract: A power transmission device includes a housing, a rotatable input member and a rotatable output member supported in the housing by a pair of bearings. A friction clutch is operable to selectively transmit a requested magnitude of torque between the input member and the output member. The clutch is axially positioned between the bearings. An actuator is operable to provide an actuation force to the friction clutch to generate the requested magnitude of torque.
    Type: Grant
    Filed: November 17, 2010
    Date of Patent: August 9, 2011
    Assignee: American Axle & Manufacturing, Inc.
    Inventor: Stuart J. Millar
