  • Patent number: 6974351
    Abstract: In an electric motor-and-gear assembly for driving automotive power accessories such as front and rear wipers, power window units, or the like, having transmission casing, that can be closed by means of a casing cover, and having a socket that is disposed in the casing cover and can be contacted by means of a connector plug in order to connect the electric motor to the electrical system of the vehicle, for the sake of a uniform, single design of the socket when there are structurally varied designs of connector plugs, the socket is attached to an interchangeable adapter which has a first group of electrical contacts adapted to the socket and a second group of electrical contacts adapted to the connector plug. The contacts of the two contact groups, which are comprised of plug tabs, are connected to one another in an electrically conductive manner inside or along a surface of the adapter.

  • Patent number: 6515399
    Abstract: An electric motor-and-gear assembly for driving vehicle aggregates such as windshield and rear window wipers, power-window units and the like, having a transmission housing that can be closed by a housing cover. A motor housing that contains a commutator motor whose commutator protrudes into the transmission housing and cooperates with a brush holder fixed in the transmission housing. For the sake of a more reasonably priced manufacture and a time-saving, more rapid assembly of the brush holder, the commutator brushes are embodied as hammer brushes with spring leaf actuators prestressed toward the commutator. The spring leaf actuator are respectively fixed with their one actuator end in a U-shaped plastic carrying part of the brush holder, which is inserted into the transmission housing radial to the commutator, through the housing opening and is positioned in the transmission housing in a positively engaging manner by means of the housing cover.

  • Patent number: 6288466
    Abstract: An electric drive unit having an electric drive motor and a transmission. The electric drive motor has an armature shaft which extends, for example, to a worm shaft of the transmission. The shaft is embodied of one piece with the armature shaft. A first bearing and a second bearing are provided to support the armature shaft. The second bearing is embodied as a ball bearing with an outer ring, an inner ring, and balls. The inner ring is press-fitted in a rotationally fixed manner onto the armature shaft. The outer ring is slid into a receiving bore disposed in the transmission housing and is pressed against an axial stop face adjoining the receiving bore by means of a retaining part that is supported in an installation channel and has flexible tongues that are directed toward the outer ring. This axial pressing can be produced in an easy-to-assemble fashion and is also inexpensive thanks to a low cost of the retaining part.
