Abstract: The invention relates to a transmission drive assembly (10) having a drive motor (11) the drive shaft (23) of which protrudes with a portion (25) thereof into a transmission housing (12), wherein the drive shaft (23) is arranged on the side facing the transmission housing (12) in a bearing (32) which is held in a form-fit or force-closed manner in a substantially sleeve-shaped holding element (35; 65) which is arranged in a holding fixture (27) of the transmission housing (12).

Abstract: The invention relates to a transmission drive unit (10; 40; 50; 70) having an adapter element made of plastic (22; 22a; 53; 73) via which a torque is initiated by an input element (29) and a drive element (12; 12a; 51; 72) made of metal for forwarding the torque, wherein the adapter element (22; 22a; 53; 73) and the drive element (12; 12a; 51; 72) are directly coupled to one another and rigidly connected, wherein the adapter element (22; 22a; 53; 73) is an injection molded part which is formed by at least partial overmolding of the drive element (12; 12a; 51; 72) and wherein the drive element (12; 12a; 51; 72) serves as a bearing element.

Abstract: A hammer brush to be supported in pivoting fashion in a brush holder of an electric machine is equipped with a leaf spring which includes a fastening section for attachment to the brush holder an arm connected to the fastening section to which a carbon brush is fastened, and a section at the end of the arm which is bent at an angle toward the fastening section. The section at the end of the arm is bent toward the side of the arm oriented away from the carbon brush and is embodied as resilient.

Abstract: A carbon brush for an electrical machine for pivotable support on a brush holder of the electrical machine includes a bearing portion embodied on the carbon brush itself for pivotably supporting the carbon brush. This can be done in the form of a bore of a cylindrical portion. This has the advantage that the position of the carbon brush relative to the commutator does not vary especially markedly even in the event of major temperature fluctuations. Moreover, the carbon brush can be well positioned in a brush holder which assures a precise association with the commutator.

Abstract: An actuator in the prior art includes a plug contact, which is disposed on a printed circuit board, and also includes a brush holder, which is not disposed on the printed circuit board but is electrically connected to it. This has the disadvantage of requiring additional electrical connections. In an actuator (1) of the invention, the brush holder (41) is loosely coupled to the printed circuit board (31) and secured to a housing (9), so that electrical connections of the brush holder (41) and printed circuit board (31) are produced simply and without additional means.

Abstract: A brush holder equipped as a component on a printed circuit board and is inserted into a recess provided in a transmission housing of the drive device and thereby can be slid in the radial direction over a commutator of an already completely assembled armature. The drive device according to the invention is provided for moving a sliding sunroof of a vehicle.
