Abstract:
1. A drive unit for an electrical geared motor, comprising: a housing, a driven wheel located in the housing and having a mounting face for a gear component which is drivable by means of the driven wheel, a sealing element disposed in the drive unit for sealing off the drive unit, the sealing element comprising a radial shaft sealing ring having a radial sealing face for sealing off from an outer component and a diametrically opposed radial sealing lip for sealing off from an inner, rotatable component, the sealing element also having an axial sealing ring for axial sealing of an axial component, the axial sealing ring being integrally formed onto the radial shaft sealing ring, wherein the axial sealing ring is joined to the radial shaft sealing ring by means of an encompassing connecting strip, wherein the connecting strip has an extent in the axial direction which is less than the extent of the axial sealing ring, and the connecting strip is thinner than the axial sealing ring or the radial shaft sealing ring, and wherein the connecting strip is made entirely of an elastic material so as to be flexible so that before the scaling element is disposed in the drive unit, the radial shaft sealing ring and the axial sealing ring are flexibly connected so that, while being formed integrally and thus being connected, they have freedom of movement with respect to each other.
