Abstract:
A driving unit for driving a motor-driven device in a private car, for example a window lifter, a windshield wiper or the like, has a disk armature motor (40) as driving motor and a planetary gear (35) as transmission. The disk armature motor (40) and the planetary gear (35) have the same axis (3) and are assembled into a driving unit that lies in the axis (3).
Abstract:
The invention concerns a windscreen wiper, in particular for passenger cars, which comprises: a first wiper arm part (11) mounted so as to pivot about a bearing shaft which is rigid with the vehicle; a pivot drive (8); a second wiper arm part (12) which is longitudinally guided in the first wiper arm part (11); a sliding drive (10); and a wiper blade which moves substantially over the whole area between the lateral edges of the windscreen as the wiper arm pivots. The pivot drive (9) and the sliding drive (10) for the second wiper arm part each comprise a sliding rotor motor (52, 55), the second sliding rotor motor (55) being disposed in the first wiper arm part (11).

Abstract:
Where the drive is for a windscreen wiper in a motor vehicle, its wiper arm has a pivotably located first wiper arm part and a second wiper arm part pivotably located in the first part. At the free end of the second arm part is a wiper blade. As pivot drive for the first wiper arm part a first disc armature motor (40) is provided and as displacement drive for the second wiper arm part a second disc armature motor is provided. The first disc armature motor composes with a planetary gear (35) a coaxial drive unit in an axis (3). The planetary gear has a first gear component (37) fixed to the bodywork of the vehicle, a second gear component (38) fixed to the movable unit, a driven rotor (36), a peripheral surface unequally spaced to the axis and a transmission component (39) moved by the rotor.
