A tandem drive device for at least one adjustable vehicle part, in particular for a sliding roof system, preferably comprising at least two sliding roof elements such as, for example, a glass roof and a roller shutter, wherein the tandem drive device includes at least a first drive system having a first gear mechanism and a first drive motor, and a second drive system having a second gear mechanism and a second drive motor, as well as a common control circuit for the first drive motor and the second drive motor, wherein the first gear mechanism and the second gear mechanism as well as the control circuit are accommodated in a common housing.

Tandem drive device

An object of the present invention is to provide an electric motor which can prevent electric noise generated from a contact between a brush and a commutator from being radiated and diffused to the outside. An electric motor comprises: an armature shaft; a coilattached to the armature shaft; a commutatorattached to the armature shaft, and electrically connected to the coil; a brush through which an electric current is supplied to the commutator; a conductive shaft bearingconfigured to rotatably support the armature shaft; a yokeincorporated with the shaft bearing, and electrically connected to a ground conductor; a conductive shaft bearingarranged in a direction along a center line of the armature shaft, different in position from the shaft bearing, and configured to rotatably support the armature shaft; and a contact plateelectrically connected to the shaft bearing, and electrically connected to the ground conductor.

Electric motor

A metal gear cover, which is provided so as to cover a worm wheel housing, is disposed between a worm wheeland a circuit boardand grounded, thereby quickly introducing exogenous noise 'ON' such as static electricity to the outside of the sunroof motor, even if exogenous noise 'ON' enters the sunroof motorand reaches the gear cover. Therefore, it is possible to surely prevent exogenous noise &#x201c;ON&#x201d; from being reflected to the circuit board, and causing the circuit boardto malfunction and the like. Furthermore, it is possible to improve reliability of the sunroof motor

An output shaft, to which the rotational force of a motor is transmitted, is rotatably supported and housed in a case. One end of the output shaft protrudes from the case, and a pinion gear is provided on this one end. Teeth that mesh with the pinion gear are provided on the outer circumferential surface of cables. A guide member for guiding the cables in such a way that they mesh with the pinion gear is mounted on the case. An urging plate portion that presses against the side of the pinion gear is provided on the guide member. The urging plate portion urges the output shaft in the axial direction and, as a result, rattle of the output shaft is alleviated.

Drive device

An output shaft to which the rotational force of a motor is transferred is housed in a case. One end side of the output shaft protrudes from a side surface of the case. A pinion gear is fixed to one end side of the output shaft. Teeth that mesh with the pinion gear are formed on the outer circumferential surface of cables. Cable guide surfaces for guiding the cables to mesh with the pinion gear are provided on the side surface of the case.

Driving device

A drive device for moving the sliding roof of a motor vehicle is provided which includes an electric motor including an armature, a pole shaft and a brush system, gearing driven by the electric motor, and a circuit arrangement for triggering the electric motor. The electric motor is accommodated in a motor housing while the gearing and at least parts of the circuit arrangement are accommodated in a gear housing connected to the motor housing. The brush system is accommodated directly in the gear housing independently of the circuit arrangement and without the interposition of additional support elements.

In a drive device, especially for a sunroof of a motor vehicle, with an electric motor () which has a pole shaft () located in a shaft housing (), and a magnet () which is mounted on the pole shaft so as to rotate with it, and at least one Hall sensor () which is located outside the shaft housing for detecting the rotary position of the magnet and thus of the pole shaft, in the area of the Hall sensor (), the wall () of the shaft housing () is, at the same time, part of the electronics housing () in which there is a board () which bears the circuitry of the electronic circuit for triggering the electric motor and at least one Hall sensor, such that the side of the board equipped with the Hall sensor faces the pole shaft () and the at least one Hall sensor is located directly adjacent to the magnet ().
