Abstract: An electric drive contains an electric motor for generating a driving force and a transmission for transmitting the driving force. The electric motor has a motor housing, a rotor arranged in the motor housing, and a motor shaft which bears the rotor. The transmission has at least two transmission elements which are coupled in terms of the transmission of force. The electric drive furthermore contains a drive housing for accommodating the electric motor and the transmission. Moreover, the motor shaft is mounted by at least a first radial bearing and a second radial bearing and braced transverse to its axis of rotation. The second radial bearing being arranged radially offset to the axis of rotation.

Abstract: A housing of a driving device, in particular an electric motor adjustment drive for a motor vehicle, has a housing opening, which is covered by a gas-permeable membrane, in particular a membrane that is impermeable to liquid. The housing opening is surrounded by a collar contour, which is interrupted locally at the circumference and within which the membrane lies.

Abstract: An adjustment drive, in particular a window winder drive of a motor vehicle. The adjustment drive has an electric motor with a brush system, the respective brush of the brush system being connected to a plug contact in order to supply power to the electric motor, and an electronics system housing in which a mating contact, with which the plug contact makes contact, is arranged. In this case, the plug contact is mounted such that it can move in the plug-contact-making direction.

Abstract: An electronics and/or gearing housing, in particular for a worm wheel of a window lifting drive, of a motor vehicle is provided. The electronics and/or gearing housing has a housing body, within which an electronic assembly is arranged, and a cover, which is joined to the housing body via ultrasonic welding.

Abstract: In a motor-gear drive unit, particularly for automobile window lifters and the like, a moisture-tight closure of the gear case (2) is provided by a gear case cover (4). The cover (4) is preferably injection-molded from plastic and can be connected to the gear case (2) nonpositively by a press-fitted, insertable clamp fastening. Specifically, the clamp fastening takes the form of a peripheral web (4.1) capable of being pressed into a peripheral channel-like groove (2.2), where the peripheral web (4.1) and the peripheral channel-like groove (2.2) are provided, respectively, on either the case (2) or the cover (4). If the peripheral web (4.1) is provided on the cover (4), a peripheral scraping rib (4.11) is molded on the inside surface of the web (4.1). An elastic gasket layer (5) having a static sealing edge (5.1) is applied, e.g., injection-molded onto an outer surface of the peripheral web (4.1).

Abstract: To reduce the outlay in terms of manufacture and assembly, a motor-gear drive unit is provided, which includes a motor housing and adjoining gear case, and in which:a) a motor-gear shaft (3) is mounted in the motor housing (1) in a first bearing, preferably a cup bearing (7);b) the motor-gear shaft (3) is mounted in the gear case (2) in a second bearing in the form of a preferably metallic, cylindrical bearing (8);c) the gear case (2) consists of a plastic part with an axially loadable bearing orifice (2.3) having circumferentially radially projecting shaped webs (2.31) for receiving the cylindrical bearing (8); andd) the cylindrical bearing (8) is pressed into the bearing receptacle (2.3) axially in bearing contact with a press fit relative to the shaped webs (2.31).
