The invention relates to a wiper drive for a rear window wiper of a motor vehicle, comprising a drive unit having a wiper shaft for the oscillating pivoting about a rotational axis, and having a protective cap surrounding the wiper shaft in an axial section, wherein the protective cap is connected to a housing of the drive unit by way of a radial press fit connection. The protective cap comprises a detent element engaging in a recess in the housing in order to absorb axial forces on the protective cap.

Wiper drive

The invention relates to a windscreen wiper drive arrangement () having a drive shaft (), extending out of a gear mechanism housing (), for a windscreen wiper, in which the drive shaft () is guided axially through a protective sleeve () which is sealed with respect to the drive shaft () by means of at least one inner sealing element () and with respect to a vehicle component () by means of at least one outer sealing element. The invention provides for the protective sleeve () to be secured to the gear mechanism housing in order to protect said protective sleeve against axial movement in the direction of the vehicle component () and/or against rotational movement relative to the gear mechanism housing () by frictional engagement and/or by means of at least one separate securing element ().

Windscreen wiper drive arrangement

A windshield wiper drive () is provided for the output shaft () with a protective cap () across a longitudinal region. The protective cap () is supported between the terminal supports thereof against the drive shaft () and the drive housing () of the windshield wiper drive () in relation to the output shaft () via a supporting bearing ().

Cap and seal for windshield wiper drive for vehicles

The present invention relates to an electrical drive unit with an electric motor and a transmission, wherein the motor has a rotor shaft (), to which a rotor () and a commutator () are fitted in a manner fixed against rotation, wherein a commutator sliding contact () is provided in order to make contact with the commutator (), and wherein an electrical connection is provided between an electrical terminal () and the commutator sliding contact (). According to the invention, one cable and one special step in the manufacturing process are dispensed with by virtue of the fact that the electrical connection runs via the rotor shaft ().

Electrical drive unit

A windshield wiper device (), in particular for a motor vehicle, with at least one drive element () having an output shaft (), which drive element is to be fastened to the vehicle body (), and at least two fastening elements (), which are able to engage in receptacle openings () on the vehicle body () and each having at least one damping element () for damping mechanical vibrations. It is proposed that the damping element () is firmly connected to the fastening element () and can be inserted into the receptacle openings () in a first assembly direction () and via a rotational movement in a second assembly direction () transverse to the first edge () of the receptacle opening () overlaps with a slot (), wherein the slot () is arranged in a component (), which has a surface that is hard relative to the damping element () and is firmly connected to the damping element ().
