The invention relates to a device comprising a first component () and a second component (). The first component () comprises a cylindrical outer surface (), and the second component () comprises a cylindrical inner surface () which is arranged on the outer surface () coaxially with a longitudinal central axis (m). First connection surfaces of the first component interact with second connection surfaces of the second component in order to prevent a relative rotational movement of the components (). The invention is characterized in that one of the connection surfaces forms a remaining toothing (), and the other connection surface forms mutually spaced longitudinal protrusions () which are distributed over the circumference and the tooth flanks of which extend parallel to the longitudinal central axis (m).

Rotary coupling

The disclosure relates to a spindle drive for a tailgate of a vehicle which can be adjusted between two drive end positions, in particular between a retracted position and an extended position, two drive connections being provided for diverting drive movements and a drive train between the drive connections, the drive train comprising a motor unit and a drive worm gear downstream of the motor unit in drive terms, the drive worm gear having a spindle with an external spindle drive and a spindle nut with an internal spindle nut thread which is in screw engagement with the external spindle thread, a brake assembly being provided for braking at least a part of the drive train of the spindle drive. The brake assembly can be adjustable in relation to its braking action and that the brake assembly is coupled for adjustment thereof with a component of the drive train.

Spindle drive

A drive arrangement for a motor vehicle functional part includes: a housing, in which a drive motor, a gear mechanism and an adjustor are provided at least partially; a drive shaft configured to transfer the adjustor via the gear mechanism from a closed position into an open position and vice versa; and a wrap spring arrangement comprising two wrap spring members, which act in opposite directions. The wrap spring arrangement is arranged on a gear mechanism output side, in a region of the adjustor.

Drive arrangement for a motor vehicle functional part

A drive for a motor-vehicle accessory has a drive motor, a controller that regulates the drive motor, and a sensor associated with the drive motor and that measures the motor speed of the drive motor and transmits to the controller a signal having a pulse rate corresponding to the motor speed. A pulse-rate modifier between the sensor of the drive motor and the controller serves to modify the pulse rate received from the drive motor in such a way that this rate is within a range of the pulse rate processable by the controller and to transmit a modified value of the pulse rate to the controller.
