The invention relates to a gear housing () comprising a gear, particularly comprising a gear of a wiper device for motor vehicles, having a housing base body (), having a housing cover () affixed at a distance to the housing base body () by means of a plurality of retaining clips () made of spring steel in circumferential direction, and having an annular seal () disposed between the housing base body () and the housing cover () and pressed against a support region () of the housing base body. The invention provides that the radial extension (y) of the support region is smaller than the radial extension (x, x') of the annular seal.

Gear housing

The invention relates to an electric drive, particularly a windshield wiper drive for vehicles, comprising an electric motor () in a crucible-shaped, preferably metal, motor housing (), a gearbox housing () that is attached to the motor housing (), and an arrangement for the interference suppression of the motor (). According to the invention, at least one choke coil () for the interference suppression of the motor () is disposed in the transition region from the motor housing () to the gearbox housing (), wherein in this transition region means () are provided in order to shield the filtered coil end () projecting into the gearbox housing () from the interfering radiation produced by the motor ().

Electric drive

An electric drive, in particular a wiper drive for vehicles, is proposed, with an electric driving motor in a motor housing (), a brush holder () projecting into the motor housing (), an anti-interference module () which is connected electrically and mechanically to the brush holder () and is intended for the electrical connection and interference protection of the motor, and with a gear mechanism () which is attached to the motor housing (), at least partially accommodates the anti-interference module () and is designed in accordance with the predetermined position of the output shaft () with respect to the drive shaft (). According to the invention, the diversity of components of the electric drive and therefore, in particular, the diversity of tools for producing the components are reduced by the anti-interference module () and the brush holder () being equipped with corresponding retaining means () which permit the installation of a structurally identical anti-interference module () on the brush holder () in two installation positions rotated through 180&#xb0;.

The present invention relates to an axial spring element, and an electric machine (), in particular for driving functional elements in a motor vehicle, with a rotor shaft (), which is rotatably supported in a housing part () of a housing via a roller bearing () An axial spring element () is located between the roller bearing () and a rotor component () installed non-rotatably on the rotor shaft (). The axial spring element () includes an inner ring () and an outer ring (), which are interconnected in an axially resilient manner, and the outer ring () is axially connected to the rotor component ().

Electric machine comprising an axial spring-loaded element

Sheet-metal blanks for rotors or stators of electrical machines are cut from rolled sheet-metal strips with a magnetic preferential direction and layered to form a laminated rotor core or laminated stator core. To compensate largely for a magnetic anisotropy of the laminated rotor core or laminated stator core, the sheet-metal blanks, when they are not centrosymmetrical, are cut out together congruently in a single cutting operation, from rolled sheet-metal strips stacked one above the other and rotated relative to one another by an angle.

Method for producing a rotor or stator of an electrical machine from sheet-metal blanks

A motor with a fan wheel for forming an axial or radial fan, having a drive unit and a control unit that has a control housing. The drive unit has a stator, a rotor, and at least one electric coil, and the control unit has an electronic circuit for open- or closed-loop control of the supply of current to the coil. The drive unit and the control unit are formed by modules, and contact elements associated with one another are provided for mutual electrical connection.
