An electrical machine (), in particular for the adjustment of movable parts in the motor vehicle, having a stator housing () which accommodates a stator () and a rotor (), wherein the rotor () has a rotor shaft () on which a commutator () is arranged, which commutator can be energized by means of electrical brushes (), and the stator housing () has an axial opening () with an encircling edge (), through which axial opening the rotor shaft () protrudes out of the stator housing (), wherein an electronics circuit board (PCB) (), which is populated with at least one interference-suppression element (), is arranged transversely in relation to the rotor shaft (), and the electronics circuit board (), in its circumferential region (), bears against the edge () in a conductive manner in order to form a ground contact with the stator housing ().

Electrical machine having an electronics circuit board which makes contact with a stator housing

The invention relates to a drive unit (), with a bearing device () for a drive motor () which interacts with a gearing element () via a drive shaft () which is supported at multiple points, with a first bearing element () which is arranged on that side of the drive motor () which is opposite the gearing element (), a second bearing element () which is arranged between the drive motor () and the gearing element (), and a third bearing element (to) which is arranged on that side of the gearing element () which faces away from the drive motor (), wherein the third bearing element (to) is arranged movably in a direction perpendicular to the longitudinal axis () of the drive shaft (), and wherein the third bearing element (to) is accommodated in a receptacle () of a gearbox ().

Drive unit

The invention relates to a transmission drive assembly () having a drive motor () the drive shaft () of which protrudes with a portion () thereof into a transmission housing (), wherein the drive shaft () is arranged on the side facing the transmission housing () in a bearing () which is held in a form-fit or force-closed manner in a substantially sleeve-shaped holding element () which is arranged in a holding fixture () of the transmission housing (). According to the invention, in an installation position for introducing and positioning the holding element () in the holding fixture () of the transmission housing (), the holding element () is positioned in a first axial end position defined by an abutment element () of the drive motor (), and, in an end position of the drive shaft () in the transmission housing (), the holding element () can be slid by means of a sliding element () on the drive shaft () into a second axial end position which is axially remote from the at least one abutment element.
