Driving Device
First Claim
1. A driving device for a hatch in a motor vehicle, the device comprising:
- a first fastening element which can be connected to a stationary structural component;
a second fastening element which can be connected to a movable structural component;
a spindle drive comprising a threaded spindle having an axis of rotation and a spindle nut arranged on the threaded spindle;
a rotary drive comprising a driveshaft for rotating said spindle about said axis of rotation to move the first fastening element axially relative to the second fastening element;
a spindle sensor for detecting revolutions of the spindle;
a stroke detection sensor for continuously detecting the position of the movable structural component, the stroke detection sensor comprising a rotatable sensor element driven in rotation by the driveshaft and a stationary sensor element for continuously detecting the rotational position of the rotatable sensor element; and
a gear reduction unit between the driveshaft and the rotatable sensor element.

Abstract
A driving device for a hatch in a motor vehicle includes a first fastening element which can be connected to a stationary structural component, a second fastening element which can be connected to a movable structural component, a spindle drive including a threaded spindle having an axis of rotation and a spindle nut arranged on the threaded spindle, and a rotary drive having a driveshaft for rotating spindle to move the first fastening element axially relative to the second fastening element. A stroke detection sensor for continuously detecting the position of the movable structural component includes a rotatable sensor element driven in rotation by the driveshaft and a stationary sensor element for continuously detecting the rotational position of the rotatable sensor element. A gear reduction unit is provided between the driveshaft and the rotatable sensor element so the revolutions of the sensor element are reduced by about 14:1.
