Cable window lifter with a driving unit

Abstract

A cable window lifter with a driving unit includes a drive housing having an internal cavity therein. A cable drum is disposed within the internal cavity and has an internal gear provided along an internal portion of the drum. A pinion gear is disposed within the internal portion of the cable drum and includes teeth that engage the internal gear of the cable drum. The pinion gear is driven manually or by a motor. A support core is disposed between a portion of the internal gear of the cable drum and a portion of the pinion gear teeth. The support core prevents the lateral deflection of the pinion gear teeth out of the internal gear of the cable drum during imposition of an overload force onto the pinion gear, thereby assuring improved running quality of the driving unit and reducing the forces occurring in the driving unit.
