Abstract: A drive unit (1) comprising at least one electric drive motor (2) that moves a functional element (3), wherein the functional element (3) assumes, during its movement, a stop position (4) for switching off an electric drive motor (2), and at least one frictional element (6) cooperating with the functional element (3), wherein the frictional element (6) is disposed along a segment of a motion pathway (5) before the functional element (3) reaches the stop position (4). In addition, a motor vehicle lock (10) having a central locking mechanism (11) with such a drive unit (1).

Abstract: The invention relates to a clutch unit, which has two subunits. One subunit is connected to the output shaft of an engine, and the other subunit is pre-mounted on the side of the transmission. Both subunits are coupled to one another via an axial plug-type connection, which includes meshing first profiles and second profiles.

Abstract: A friction clutch wherein a rotary housing supports a tiltable diaphragm spring and confines a pressure plate that is axially movably but non-rotatably mounted therein for movement toward and away from friction linings on a clutch disc between the pressure plate and a prime-mover-driven counterpressure plate. The diaphragm spring is arranged to urge the pressure plate in a direction to engage the clutch and is maintained in stressed condition within the housing, even when not installed in the power train of a motor vehicle. The diaphragm spring is installed so that it is operatively associated with the pressure plate in an elastically stressed condition. The pressure plate includes an annular portion that supports the diaphragm spring, and further supports a biasing arrangement that is radially offset relative to the supporting portion and that serves to maintain the diaphragm spring on the pressure plate in the resiliently stressed condition.
