A power actuator is configured for a hinged vehicle door with a generally vertical hinge axis. The power actuator includes a motor-gearbox assembly, a slip clutch, a friction brake, a threaded spindle with a motor-side bearing, and a spindle nut affixed to a spindle tube, configured to travel along the threaded spindle during a rotation of the spindle. The slip clutch and the friction brake are operatively positioned between the motor-gearbox assembly and the motor-side bearing. The power actuator does not need to include a biasing element acting on the spindle nut toward an extended position because such a biasing element is unnecessary where the hinge axis is generally parallel to the direction of gravity.

The invention relates to a planar spiral gearbox, in particular for use in a door system, comprising: a gear, in particular a scroll plate, having a planar side on which a spiral toothed arrangement is arranged having at least one tooth that has a spiral tooth progression; and a cylindrical gear, in particular a torus gear, that has an external toothed arrangement at its jacket surface, wherein the spiral toothed arrangement of the gear is in meshing engagement with the external toothed arrangement of the cylindrical gear, with the gear having at least one additional toothed arrangement section that is radially spaced apart from an axis of rotation of the gear and serves for engagement of a drive toothed arrangement.

A drive for a flap, wherein the drive has a housing, a motor and a spindle drive, wherein the motor and the spindle drive are drivingly connected to one another and make a motorized adjustment of the flap possible, wherein the drive moves the flap at least into an open position and a closed position, wherein the spindle drive has a threaded spindle with a nut and a thrust tube and the thrust tube is connected to the threaded spindle via the nut, wherein the thrust tube is moved via a translational movement, wherein the spindle drive is arranged inside a rotor and the motor drives the rotor, wherein the rotor is connected to the threaded spindle.

A spindle drive assembly for opening and/or closing a vehicle flap is described, having a spindle and a spindle drive motor coupled thereto by means of a two-stage epicyclic gearing. A ratio of a number of teeth of each planet gear of a first epicyclic gearing stage to a number of teeth of each planet gear of a second epicyclic gearing stage is selected such that, in operation, a first sound frequency that is emitted by the first epicyclic gearing stage differs by an integer multiple of a semitone from a second sound frequency that is emitted by the second epicyclic gearing stage. In addition, a vehicle flap with such a spindle drive assembly is presented.

A door system having a linkage assembly with a drive arm and an attendant arm coupled at the ends through a gear joint. The gear joint has drive teeth on an end of the drive arm and attendant teeth on an end of the attendant arm. The drive arm is coupled to a motor in the door system that is coupled to a door, or a door frame or a wall. The attendant arm is coupled to the opposite of the door, or the door frame or the wall to which the door system is coupled. When the door system is installed on the push side or the pull side of the door the drive arm and the attendant arm are parallel with the door and the upper door frame. During operation the motor transfers the torque from the motor through the gear joint to open the door.

An embodiment vehicle hinge driving apparatus includes an actuator, a housing connected to the actuator, an output shaft rotatably mounted in the housing, a transmission mechanism configured to transmit a torque from the actuator to the output shaft, and a brake unit mounted on the transmission mechanism. An embodiment method for providing a vehicle hinge driving apparatus includes rotatably mounting an output shaft in a housing that is connected to an actuator, providing a transmission mechanism that transmits a torque from the actuator to the output shaft, and mounting a brake unit on the transmission mechanism.

A powered actuator for moving a motor vehicle closure panel from a closed position to an open position and method of construction thereof. Powered actuator includes an electric motor configured to rotate a driven shaft and a gearbox coupled to the driven shaft. An extensible member extends through the gearbox to a proximal end on one side of the gearbox for attachment to one of a vehicle body or the closure member and to a distal end on an opposite side of the gearbox. Extensible member is configured to move between retracted and extended positions in response to rotation of the driven shaft. A contamination cover enshrouds the extensible member between the gearbox and the distal end of the extensible member. Contamination cover moves between an axially extended state and an axially retracted state while the extensible member moves between the respective retracted position and the extended position.

A planetary gear device includes: a housing cover disposed at one end portion of a housing in an axis direction, the housing being configured to house a sun gear and a planetary gear inside the housing; and a carrier cover disposed next to the housing cover in the axial direction in the inside, and configured to support a shaft of the planetary gear from one end portion side in the axial direction. One opposing part of a pair of opposing parts opposite to each other in the housing cover and the carrier cover includes a cone-shaped part whose diameter varies in the axial direction, and the other opposing part of the pair of opposing parts includes a sliding part configured to slide on a peripheral surface of the cone-shaped part with a same axis as an axis of the cone-shaped part.

A drive device has a transmission housing with an external rotor-type electric motor. The electric motor is coupled to the transmission and is actuated by a motor electronic unit. The electric motor has a stator and a rotor which circulates about the stator and is connected to a drive shaft that is guided through a stator bushing with a first sleeve section for holding the stator bushing in the transmission housing in a rotationally fixed manner and with a second sleeve section. A groove frame insulation which surrounds the stator teeth in the axial direction is placed on the second sleeve section. An annular element which is arranged between the first sleeve section and the groove frame insulation and which has a joint element is placed on the second sleeve section of the stator bushing. The joint element engages into a joint contour of the first sleeve section.

A control device is used to move a pick-up truck tailgate. The control device comprises a first gear arrangement connected to a drive cup and a second gear arrangement that is connected to a motor for driving the second gear arrangement. The control device also includes a clutch arrangement positioned between the first and second gear arrangements. When the clutch arrangement is in an engaged position, it couples the first gear arrangement and the second gear arrangement to transmit torque to the first gear arrangement and the drive cup. When the clutch arrangement is in the disengaged position, the first and second gear arrangements are not coupled. Optionally, the control device comprises a brake unit to slow or stop movement of the tailgate. The control device can be positioned within the pick-up truck tailgate.
