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.

Interchangeable adapter for electric motor-and-gear assembly

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.

Electric motor-and-gear assembly for vehicle accessories

An electric drive unit for vehicle systems, such as power windows and windshield wipers, having a commutator motor that has a commutator and at least two commutator brushes. The electric drive unit includes electrical components of an electronic system for the motor. To reduce production costs and simplify assembly, the electrical components are electrically secured to a lead frame that makes the electrical connection between the components and the commutator motor and the commutator brushes are embodied as hammerhead brushes, whose carrier plates are bent in one piece out of the lead frame.
