Abstract: An assembly of a brush system (3) can be simplified by at least one mechanical contact element (33) for providing an external interface. The external interface electrically connects the brush system (3) to a connecting element (4) outside the brush system (3), for example a printed circuit. Provision of the external interface on the brush system (3) allows to assemble the electric actuator (1) in separate assembly steps.

Abstract: In order to find a simple and robust drive solution with a low installation space requirement, a drive (1) for use in a motor vehicle with a motor (2), at least two drive output shafts (16, 16?; 31, 31?) for moving drive output pinions (9, 9?), and a transmission, which is arranged between the motor (2) and the drive output shafts (16, 16?; 31, 31?), for selectively transmitting the drive input movement of the motor (2) to the drive output pinions (9, 9?) is proposed, wherein the transmission has a number of switchable clutches (11, 11?, 14, 14?; 32, 32?, 34, 34?) and at least one switching element (23) for simultaneously changing the transmission capacity of one or more clutches (11, 11?, 14, 14?; 32, 32?, 34, 34?).

Abstract: An electric-motor driven actuator has a housing, in which a motor and a carrier plate are arranged and the carrier plate is connected in a fixed manner to a brush holder. The brush holder has a first brush holder which is rigidly connected to the carrier plate. A second brush holder component is also provided which is mechanically coupled to the first brush holder component and is decoupled in a vibration-neutralizing manner from the first brush holder component via at least one damping element and which holds brushes via which contact can be made with a commutator of the motor.

The brush holder (5) has a first brush holder component (51), which is connected rigidly to the carrier plate (4).

Abstract: In order to be able to attach a rotational-speed or direction-of-rotation transmitter, in particular in the form of a rotor (3), to the circumference of a rotor shaft (2) in a simple and reliable fashion, the rotational-speed or direction-of-rotation transmitter is connected indirectly to the rotor shaft (2) by means of at least one separate, radially resilient or elastic intermediate securing part. Preferably, at least one rubber ring (4 or 5) is provided as the intermediate securing part and is clamped onto the rotor shaft (2) or pressed into a shaft orifice of the rotor (3) expediently before final assembly, to provide a premounted unit.
