  • Positioning device for shifting gears in a transmission having an output component capable of two types of motion
    Patent number: 6155129
    Abstract: A positioning device for an output component for automatically shifting gears of a motor vehicle transmission that undergoes two types of movements comprises a plurality of drives. The movement of each drive can be transmitted via a transmission mechanism to the output component. A first drive causes the output component to undergo movement of a first type, and a second drive causes the output component to undergo movement of a second type. The first drive is connected to a sliding element. The sliding element is axially fixed, but movable in the circumferential direction relative to the output component. The second drive is rotatably fixed, but axially movable output component.

  • Friction clutch having an actuator for automated operation
    Patent number: 5934433
    Abstract: An actuator for automated operation of a friction clutch includes a drive that is connected with an input part of a gearing and an output part of the gearing that is movable into operative connection via a transmission member with a disengagement bearing of the friction clutch. The transmission element has a pitch region rotatable for driving an engagement element into force-applying contact with a disengagement bearing for displacing the disengaging bearing and thereby disengaging the clutch.
