Abstract
Disclosed is an actuator for the rotary drive of a vehicle flap. The actuator includes an electric motor, which has a output shaft with a center axis, an output unit, which is in force-transmitting connection with the electric motor in such a manner that activation of the electric motor causes a rotational displacement of the output unit about an axis of rotation of the output unit, and a mounting unit which is configured to support the actuator in force-transmitting connection with a superordinate assembly relative to the drive unit such that, upon activation of the electric motor, a displacement of the drive unit relative to the mounting unit takes place. Also disclosed is a storage apparatus for a vehicle door and a motor vehicle.
Claims18
An actuator for rotationally driving a vehicle flap, the actuator comprising:
- an electric motor which has an output shaft with a central axis about which the output shaft rotates in response to activation of the electric motor, and which is configured to provide a drive force by means of which the vehicle flap can be displaced;
- an output unit which is in force-transmitting connection with the electric motor in such a manner that activation of the electric motor causes a rotational displacement of the output unit about an axis of rotation of the output unit;
- and
- a mounting unit which is configured to support the actuator in force-transmitting connection with a superordinate assembly relative to the output unit, such that, upon activation of the electric motor, a displacement of the output unit relative to the mounting unit takes place,
- wherein the center axis of the output shaft of the electric motor is spaced from and substantially parallel to the axis of rotation of the output unit,
- wherein the actuator comprises a clutch which is configured to interrupt power transmission from the output shaft of the electric motor to the output unit in its disengaged state or to produce the same in its engaged state,
- wherein the clutch comprises a first gear, which has a toothing pointing radially inwards, and a second gear, which has a toothing pointing radially outwards, wherein the first gear and/or the second gear is/are displaceable between a relative position in which the first and second gears mesh with one another to form the engaged state of the clutch and a relative position in which the first and second gears are disengaged from one another to form the disengaged state of the clutch.
