Abstract: The clutch device comprises a first clutch element and a second clutch element, which are each supported in a rotational manner on a common axis of rotation. In an engaged state, the clutch elements are coupled to one another in a form-locking manner by a sliding sleeve. The sliding sleeve is attached to the first clutch element in a rotationally fixed and axially displaceable manner. A peripheral surface of the sliding sleeve is provided with at least one step, having a first step flank and extending with a first step course on the peripheral surface of the sliding sleeve, wherein the first step course also has, at least in sections, at least one axial directional component in the direction of the axis of rotation. A placement agent can be displaced radially back and forth between an engaging placement agent position and a disengaging placement agent position, and is otherwise stationary.

Abstract: A device (1) for actuating a parking lock comprises an emergency release mechanism. The device (1) for actuating the parking lock comprises an electric actuator (2) with an actuator output element (3) which is moveable in translation, and the actuator output element (3), when moved in a first direction, disengages the parking lock and when moved in an opposite second direction, engages the parking lock. The actuator output element (3) is connected to the parking lock by a clutch (6), and the clutch is disengageable, by the emergency release mechanism, to permit manual movement of the clutch in the first direction to disengage the parking lock.

Abstract: A parking lock mechanism for a transmission which comprises a mechanical locking device, a movable thrust element that is connected to the mechanical locking device such that the thrust element can move the locking device between locked and unlocked conditions. The lock mechanism includes a parking lock actuation device with a first movable output element, an emergency actuation device with a second movable output element, and a first elastic element. The first output element is connected, via the first elastic element, to the thrust element so that movement of the first output element can be transmitted, via the first elastic element, to the thrust element, and the second output element is directly connected to the thrust element. The thrust element has a recess in which one side of the elastic element contacts a first wall of the recess and another side of the elastic element contacts the first output element.
