摘要:
The subject matter of the invention is an electric motor-driven servo-drive for use in technical means, especially motor vehicles, with a small electric drive motor (2) with a motor shaft (4) which is provided with a gear form-fit element (3) at at least one location, proceeding especially from the end, with a worm (5) of a worm gear pair, the worm (5) slipped onto the motor shaft (4), and with a worm wheel (6) of the worm gear pair, the wheel (6) consisting preferably of plastic and coupled to the worm (5) via teeth which engage one another. It is characterized in that the worm (5) consists of plastic, that a driver (7) consisting of a harder material which transfers higher torques than the plastic of the worm (5) is slipped onto the motor shaft (4) and with the corresponding shaft form-fit element engages the gear form-fit element (3) of the motor shaft (4), that the driver (7) on a diameter which is much greater than that of the motor shaft (4) has a worm form-fit element, and that the worm (5) for its part has a driver form-fit element which engages the worm form-fit element of the driver (7).

The invention relates to a drive unit (10), especially for adjusting mobile parts in a motor vehicle, and to a method for producing such a drive unit. The drive unit comprises a housing (12) which is provided with an opening (18), leading towards the surroundings (23), on which a gas-permeable, liquid-impermeable membrane (20) rests. The housing (12) has a first housing part (14) with a peripheral collar (26) and a second housing part (16) obturating the first housing part (14). The opening is injection-molded to the second housing part (16) with a peripheral contact surface (28) which forces the membrane (20) against the collar (26) of the first housing part (14) once the housing (12) is closed.
