Abstract

A driving device has a housing tube that can be connected to a stationary base part, particularly to a vehicle body, or to a movable structural component part, particularly a vehicle hatch or vehicle door, a protective tube connected to the other respective part, a spindle drive that has a threaded spindle and a spindle nut arranged on the threaded spindle by which the housing tube and protective tube are movable axially relative to one another, and a rotary drive that drives the spindle drive in rotation and includes at least one electric motor. A sensor device conveys the current position in relation to the earth'"'"'s magnetic field or plumb line and one or more corresponding signals to a control device is arranged in the driving device.

Claims

1. A driving device comprising:

a housing tube connectable to one of a stationary base part and a movable structural component part;

a protective tube connectable to the other of the movable structural component part and the stationary base part;

a spindle drive having a threaded spindle and a spindle nut arranged on the threaded spindle by which the housing tube and protective tube are movable axially relative to one another;

a rotary drive configured to drive the spindle drive in rotation that comprises at least one electric motor; and

a sensor device arranged in the driving device configured to convey a current position in relation to one of Earth'"'"'s magnetic field and a plumb line and one or more corresponding signals to a control device.

2. The driving device according to claim 1, further comprising a safety circuit arranged on an electronics circuit board in the housing tube.

3. The driving device according to claim 1, wherein the stationary base part is a vehicle body.

4. The driving device according to claim 1, wherein the movable structural component part is one of a vehicle hatch and a vehicle door.
