  • Patent number: 11933367
    Abstract: The invention relates to a device comprising a first component (11) and a second component (12). The first component (11) comprises a cylindrical outer surface (13), and the second component (12) comprises a cylindrical inner surface (17) which is arranged on the outer surface (13) 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 (11, 12). The invention is characterized in that one of the connection surfaces forms a remaining toothing (22), and the other connection surface forms mutually spaced longitudinal protrusions (18) which are distributed over the circumference and the tooth flanks of which extend parallel to the longitudinal central axis (m).

  • Patent number: 11015378
    Abstract: 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.

  • Patent number: 9751437
    Abstract: 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.

  • Publication number: 20160218658
    Abstract: The invention relates inter alia to a drive (10) for a component (13) for a motor-vehicle accessory comprising a drive motor (16) and a controller (17) regulating the drive motor (16), and a sensor associated with the drive motor (16) measures the motor speed (nMotor) of the drive motor (16) and transmits a pulse rate (PMotor) corresponding to the motor speed to the controller (17). The special feature is that a pulse-rate modifier (18) is provided between the sensor of the drive motor (16) and the controller (17), and modifies the pulse rate (PMotor) received from the drive motor (16) in such a way that this rate is within a range of the pulse rate (PSteuergeratMax) processable by the controller (17), and that the pulse-rate modifier (18) transmits a modified value of the pulse rate (PReduz) to the controller (17).

  • Patent number: 9399916
    Abstract: A fluid-actuated rotary drive device is provided, with a housing (2) in which is formed a working chamber (3), in which is a swivel piston (18) able to swivel around a central axis (5). Also fitted or able to be fitted in the working chamber (3) is a space divider and stop unit (38), comprised of a space divider element (24) and at least one stop element (42) fixed to the former. The components of the space divider and stop unit (38) are fitted to one another by snap-in connection, so that the space divider and stop unit (38) is easy to handle during its installation in the working chamber (3).
