Abstract: A motor vehicle screen wiper drive unit is a motorized reduction gear unit comprising a reduction gear train between a driving shaft, driven by a motor, and a driven shaft. The gear train comprises at least one worm fixed to the driving shaft and meshing with a first set of teeth of an intermediate gear wheel. The latter also has a second set of teeth meshing with a driven gear wheel which is carried by the driven shaft. The second teeth of the intermediate gear wheel, and the teeth of the driven wheel, are generally helical, being so oriented that the driven wheel exerts an axial force urging the intermediate gear wheel in a direction opposite to that in which the worm is urged by an axial force exerted on the intermediate wheel by the worm. The need for rigid abutment means for the intermediate wheel is thereby avoided.

Abstract: A drive unit for a motor vehicle screen wiper comprises a motor, a reduction gearbox and an electrical connector. The gearbox has a gearbox body, on which a closure plate is fastened. Electrically conductive strips are associated with the closure plate and make the electrical connections between the motor, the gearbox and the connector. The drive unit has a cover fixed on one face of the closure plate, with the connecting strips being interposed between this face and the cover, the closure plate and the cover defining between them a closed housing containing the connecting strips.
