Abstract: A drive arrangement configured to provide motorized adjustment of an adjusting element of a motor vehicle and including a motor, a driveshaft extending from the motor, an output shaft, a spindle configured to translate to adjust the adjusting element, a coupling configured to selectively couple and decouple the spindle from the motor, the coupling, a housing, and a sensor. The coupling including a coupling element configured to generate a signal indicative of rotation angle of the coupling element. The coupling, the output shaft and at least a portion of the driveshaft disposed in the housing. The sensor disposed in the housing and configured to detect the signal.

Abstract: A drive assembly for motorized adjustment of an adjusting element of a motor vehicle. The drive assembly includes a drive having a rotational motor unit and a feed gearing drivingly arranged downstream of the motor unit for generating drive movements along a feed gearing axis in first and second adjusting directions, the drive includes a clutch having a first clutch element, rotationally fixed to a driveshaft of the drive, and a second clutch element, rotationally fixed to an output shaft of the drive, in a state in which they are drivingly coupled to one another, the clutch elements transmit rotational movements from the driveshaft to the output shaft, to generate the drive movements of the feed gearing. The clutch is designed as a curved tooth coupling.

Abstract: A door drive apparatus for adjusting a vehicle door relative to a vehicle body including an adjustment part for power transmission between the vehicle door and the vehicle body, a drive motor and a gear assembly coupling the drive motor to the adjustment part. The gear assembly includes a guide rail and a sliding element guided longitudinally on the guide rail along an adjustment direction, which is adjustable by the drive motor and is coupled to the adjustment part, and the guide rail includes two legs extended parallel to each other along the adjustment direction and the sliding element is guided between the legs along the adjustment direction.

Abstract: The disclosure relates to a linear unit for a flap arrangement with a flap, and a closed position, wherein the linear unit has two drive connections which are coupled to each other via a gearing and are adjustable relative to each other along a geometrical linear axis, wherein the linear unit has a helical spring arrangement, wherein the helical spring arrangement has a first spring element which is configured as a helical spring and a second spring element which is configured as a helical spring, with which helical springs the two drive connections can be pretensioned against each other, wherein the second spring element is oriented coaxially with respect to the first spring element with regard to a geometrical spring axis. It is proposed that the spring wire at one end of the second spring element forms a supporting portion via which the first spring element secures the second spring element axially.
