Abstract
A drive apparatus for an adjusting device for adjusting a vehicle part, in particular a window lifter, comprising a carrier element, a transmission element which can be driven by means of a motor unit, and a drive housing which is arranged on the carrier element and which has a bearing element for rotatably bearing the transmission element about an axis of rotation. The carrier element has at least one first positive-locking element and the drive housing has at least one second positive-locking element, which are in engagement with one another for a rotation-preventing securing action, wherein an elastic dampening element is arranged between the at least one first positive-locking element and the at least one second positive-locking.
Claims16
A drive apparatus, the drive apparatus comprising:
- a carrier element;
- a motor unit;
- a transmission element configured to be driven by the motor unit;
- and
- a drive housing arranged on the carrier element and including a bearing element for rotatably bearing the transmission element about an axis of rotation;
- wherein the carrier element includes at least one first positive-locking element and the drive housing includes at least one second positive-locking element, the at least one first positive-locking element and the at least one second positive-locking element are engaged to one another to provide a rotation-preventing securing action,
- wherein an elastic dampening element arranged between the at least one first positive-locking element and the at least one second positive-locking element such that the first positive-locking element and the second positive-locking element are supported in damped fashion relative to one another along at least one spatial direction via the elastic dampening element in a first load state, but come into contact with one another in a second load state, wherein the second load state having a load greater than a load of the first load state,
- wherein one of the at least one first positive-locking element and the at least one second positive-locking element includes a positive-locking pin and the other of the at least one first positive-locking element or the at least one second positive-locking element defines a positive-locking opening,
- wherein the positive-locking pin includes a central portion, and the elastic dampening element is arranged on the central portion.
A drive apparatus, the drive apparatus comprising:
- a carrier element;
- a motor unit;
- a transmission element configured to be driven by said motor unit;
- and
- a drive housing arranged on the carrier element and including a first bearing element for rotatably bearing the transmission element about an axis of rotation;
- wherein the carrier element includes at least one first positive-locking element and the drive housing includes at least one second positive-locking element, the at least one first positive-locking element and the at least one second positive-locking element being in engagement with one another for a rotation-preventing securing action,
- wherein an elastic dampening element is arranged between the at least one first positive-locking element and the at least one second positive-locking element and acts such that the first positive-locking element and the second positive-locking element are supported in damped fashion relative to one another along at least one spatial direction via the elastic dampening element in a first load state, but come into contact with one another in a second load state associated with a larger load than the first load state,
- wherein the drive apparatus includes a cable drum and a cable exit housing arranged on a side of the carrier element facing away from the drive housing, wherein the cable exit housing includes a second bearing element for rotatably bearing the cable drum about the axis of rotation.
A drive for a power window actuator, the drive comprising:
- a carrier including a first positive-locking element;
- a transmission element configured to be driven by a motor;
- a drive housing arranged on the carrier and including a bearing element, configured to engage the transmission element such that the transmission element is rotatable about a rotational axis, and a second positive-locking element;
- and
- an elastic dampening element disposed between the first positive-locking element and the second positive locking element, wherein the first positive-locking element is a pin and the second positive-locking element defines an opening configured to receive the pin and the elastic dampening element.
