Actuating device
Actuating device for a vehicle part movable relative to a body of a vehicle, and in particular a vehicle door or a vehicle hatch, including a drive assembly having a drive unit and a drive element driven by the drive unit, and an actuating element which can be displaced relative to the drive assembly along a displacement axis by means of the drive unit, where the actuating element is connected to a carriage assembly which is in threaded engagement with a spindle, where the spindle can be driven rotationally about an axis of rotation by the drive unit, and where in that a central axis of the drive element is oriented at an angle to a plane which is defined by the displacement axis and the axis of rotation of the spindle.
1 . An actuating device for a vehicle part movable relative to a body of a vehicle, the actuating device comprising:
a drive assembly having a drive unit and a drive element driven by the drive unit, and an actuating element which can be displaced relative to the drive assembly along a displacement axis by the drive unit,
wherein the actuating element is connected to a carriage assembly which is moveable along a spindle,
wherein the spindle can be driven rotationally about an axis of rotation by the drive unit,
wherein the carriage assembly comprises a spindle nut which is in threaded engagement with the spindle,
wherein the carriage assembly is pivotable relative to the spindle nut,
wherein a central axis of the drive element is oriented at an angle to a plane which is defined by the displacement axis and the axis of rotation of the spindle,
wherein the axis of rotation of the spindle extends in a horizontal direction, and
wherein the carriage assembly is pivotable relative to the spindle nut such that the actuating element is vertically tiltable relative to the horizontal direction.
2 . The actuating device according to claim 1 ,
wherein the drive element is a worm which meshes with a worm wheel connected to the spindle.
3 . The actuating device according to claim 1 ,
wherein the axis of rotation of the spindle is oriented substantially parallel to the displacement axis.
4 . The actuating device according to claim 1 ,
wherein an angle between the central axis of the drive element and the plane which is defined by the displacement axis and the axis of rotation of the spindle is from 3° to 10°.
5 . The actuating device according to claim 4 , wherein the angle between the central axis of the drive element and the plane which is defined by the displacement axis and the axis of rotation of the spindle is from 5° to 8°.
6 . The actuating device according to claim 4 , wherein the angle between the central axis of the drive element and the plane which is defined by the displacement axis and the axis of rotation of the spindle is from 6° to 7°.
7 . The actuating device according to claim 1 ,
wherein the carriage assembly comprises at least one guide portion which is configured to engage with a respective corresponding counter-portion of a housing surrounding the carriage assembly.
8 . The actuating device according to claim 7 ,
wherein the at least one guide portion comprises a material which is different from a portion, on which at least one the guide portion is arranged, of the carriage assembly.
9 . The actuating device according to claim 7 ,
wherein the spindle nut comprises the at least one guide portion.
10 . The actuating device according to claim 1 , wherein the actuating element is connected to the carriage assembly such that vertical tilting of the actuating element relative to the carriage assembly is prevented.
11 . An actuating device for a vehicle part movable relative to a body of a vehicle, the actuating device comprising:
a drive assembly comprising a drive unit and a drive element driven by the drive unit; and
an actuating element configured to be displaced relative to the drive assembly along a displacement axis by the drive unit,
wherein the actuating element is connected to a carriage assembly which is moveable along a spindle,
wherein the spindle is configured to be driven rotationally about an axis of rotation by the drive unit,
wherein the carriage assembly comprises a spindle nut which is in threaded engagement with the spindle,
wherein the carriage assembly is configured to be displaced relative to the spindle nut while the carriage assembly displaces the actuating element along the displacement axis, and
wherein a central axis of the drive element is oriented at an angle to a plane which is defined by the displacement axis and the axis of rotation of the spindle,
wherein the axis of rotation of the spindle extends in a horizontal direction, and
wherein the carriage assembly is displaceable relative to the spindle nut such that the actuating element is vertically tiltable relative to the horizontal direction.
