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.

Drive device

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 ().

Drive device for a motor vehicle sunroof

In a drive device, especially for a sliding roof of a motor vehicle, with an electric motor ( ), gearing ( ) which is driven by the electric motor, and a circuit ( ) for triggering the electric motor, the gearing ( ) is accommodated in a gear casing ( ) with at least one casing wall ( ) of high thermal conductivity and at least part of the circuit ( ) is located adjacent to this casing wall ( ) outside of the gear casing ( ). Furthermore, contact ( ) is made between the components ( ) of the circuit ( ) and the casing wall ( ) in order to dissipate the heat which forms during operation of the circuit ( ) to the casing wall ( ).

Drive device for a sunroof of a motor vehicle

A sliding motor vehicle roof with two rigid covers ( ) for closing and at least partially exposing a roof opening ( ) which is bordered by the roof frame in the fixed roof surface ( ), with an displacement means for the ventilation position of the two covers ( ), and with a head liner which has a front and a rear headliner part ( ) and which can be moved at least partially independently of the cover position in the direction of the lengthwise axis of the motor vehicle by the displacement means. It is provided that, in order to produce the front horizontal ventilation gap ( ) in front of the front edge of the front headliner part ( ) and the rear horizontal ventilation gap ( ) between the two headliner parts ( ), the front headliner part ( ) is coupled to the rear headliner part ( ). The front headliner part ( ) can be moved from the closed position into the position which opens the front ventilation gap ( ), and the rear headliner part ( ) can be moved away from the front headliner part ( ) by the ventilation position motion of the cover ( ) to clear the rear ventilation gap ( ).

Motor vehicle roof with two covers and two head liner parts

An improved motor vehicle roof is provided which includes a roof opening provided in a fixed roof surface, at least one closing element for selectively at least partially closing the roof opening, an electrical adjusting drive for driving the closing element and a sensor engineering system for detecting a situation which adversely affects the safety of the passengers and for producing a corresponding danger signal. Importantly, the roof includes a quick-action closing device coupled to the sensor engineering system which causes the closing element to close from its open or partially open position when a danger signal is present. The closing device includes means for producing an electrical voltage which exceeds the normal feed voltage (rated voltage) of the adjusting drive by several times, and for applying the voltage to the electric adjusting drive.
