Abstract (en)

The actuating drive has a motor with main drive pinion whose rotational axis is at an angle to the swivel axis of the coupling of the coupled gear. A gear connection is formed by a spindle-nut combination (19,23) where the spindle(19) forms the main drive pinion. The coupling (13) loaded by the spindle is movable at least towards the spindle and is swivel joined to the nut (23) crosswise to the spindle.
