The invention relates to a transmission arrangement, particularly for adjusting devices in motor vehicles, comprising a gear wheel, which is secured against axial displacement on an axis or a shaft by means of securing element. According to the invention, the axis or the shaft is made of plastic. The securing elements comprise at least a molded part, which has at least one axial stop for the direct or indirect support of the gear wheel, and the molded part is secured by means of a screw against axial displacement on the axis or the shaft.

Disclosed is a commutator motor, in particular an actuating motor for automotive power accessories such as power window units, sunroofs, and the like, having a brush holder attached to the motor housing and having a device for rotation detection (speed and/or rotation direction) of the motor, which has a pulse generator non-rotatably supported on the motor shaft and at least one pulse receiver affixed to the brush holder, in order to precisely affix the pulse receiver to the brush holder without having to use special fasteners, the pulse receiver is disposed in a positively engaging manner in a pocket formed into the base body and the base body encompasses the pulse generator in a contact-free manner.

There is provided an apparatus for regulating the position of an adjustably positionable vehicle part such as a window or movable roof. The apparatus includes an electric drive motor having a drive shaft which is axially displaceable within a fixed limit during driving operation of the shaft. The apparatus also includes a power transfer assembly having a driven member operatively connected to the drive shaft of the electric drive motor for driving movement thereby and a damping member for damping the axial displacement of the drive shaft of the electric motor in one axial direction. The apparatus further includes a housing having a chamber compatibly dimensioned with respect to the damping member for receiving the damping member therein in a press fit disposition.

A pole wheel of the type driven in rotation by a shaft employs a sensor system disposed on the pole wheel for detecting rotations of the shaft. The pole wheel includes a first component in the form of a hollow magnet body and a second component that is disposed as a retaining part for the first component and is seated firmly on the shaft and is embodied integrally, for the sake of streamlined connection to the first component, with connecting means. Recesses, which for instance can be embodied in groovelike fashion, may be disposed on the second component, that is, the retaining part seated solidly on the shaft, and the first component is injected molded onto the second component, creating positive engagement connecting means comprising the material of the magnet body.
