  • Publication number: 20170130814
    Abstract: An electromechanical clutch for an electronic limited slip differential constructed in accordance to one example of the present disclosure includes a clutch pack, a first lever, a second lever and an actuator assembly. The clutch pack has first and second sets of clutch plates. The first lever arm is rotatably fixed at a pivot pin. The second lever arm is rotatably fixed at the pivot pin. The actuator assembly is configured to rotatably pivot at least one of the first and second lever arms relative to the other of the first and second lever arms whereby the first and second sets of clutch plates are selectively pressed together to thereby lock the electromechanical clutch.

  • Publication number: 20170130815
    Abstract: A torque vectoring system constructed in accordance to one example of the present disclosure includes a differential, a first drive axle, a second drive axle, a first gear train and a second gear train. The first drive axle is operably coupled to the differential. The second drive axle is operable coupled to the differential. The first gear train is selectively driven by the differential and is configured to selectively supply a speed application from the differential to one of the first and second drive axles. The second gear train is selectively driven by the differential and is configured to selectively supply a speed reduction from the differential to one of the first and second drive axles.

  • Publication number: 20070191173
    Abstract: An improved differential gear mechanism is characterized by a lockout mechanism (63) operably associated with a flyweight mechanism (53) and including a lockout member (65, 101) positionable, in response to an input signal, in a normal condition and a lockout condition. In the normal condition, the lockout member (65, 101) permits a flyweight stop surface (57) to move from the retracted position to the extended position. In the lockout condition, the lockout member (65, 101) prevents the flyweight stop surface (57) from moving from the retracted position to the extended position.

  • Publication number: 20070191174
    Abstract: An improved differential gear mechanism is characterized by a lockout mechanism (129) operably associated with a latch member (119) that cooperates with a flyweight mechanism (53) to retard differentiating action in the differential gear mechanism. The lockout mechanism (129) includes a lockout member (131) positionable, in response to an input signal, in a normal condition and a lockout condition. In the normal condition, the lockout member (131) permits the latch member (119) to move freely between a locking position and an unlocking position. In the lockout condition, the lockout member (131) prevents the latch member (119) from moving into the locking position.

  • Publication number: 20070142157
    Abstract: A differential having means (35) operable to limit rotation of an output gear (23) relative to a gear case (11), and actuation means (55) for actuating the rotation limiting means, from an unactuated (FIG. 1) to an actuated condition (FIG. 4). The rotation limiting means includes a member (47), toward one axial end of the gear case and moveable between a first position, the unactuated condition of said rotation limiting means, and a second position, the actuated condition. A sensor assembly is adjacent the one axial end of the gear case and includes a sensor element (71) and a wall-like member between the rotation limiting means and the actuation means. The wall-like member includes a non-ferromagnetic portion (73) between the sensor and the moveable member. Movement between the first and second positions results in a corresponding change in the electromagnetic flux (F) coupling the sensor element and the moveable member.
