Abstract

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.

First claim

The invention claimed is:

1. A tandem drive device for a sliding roof system, comprising at least two sliding roof elements, comprising:
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,
a common control circuit for the first drive motor and the second drive motor, wherein the first gear mechanism and the second gear mechanism, and the control circuit are accommodated in a common housing,
wherein the first drive motor and/or the second drive motor are/is at least in part disposed outside the common housing,
wherein:
the first gear mechanism and the second gear mechanism overlap at least in portions in an axial direction defined by a rotation axis of the first drive motor, or the first gear mechanism and the second gear mechanism overlap at least in portions in an axial direction perpendicular to the rotation axis of the first drive motor;
wherein the first drive system including the first gear mechanism and the first drive motor on the one hand, and the second drive system including the second gear mechanism and the second drive motor on the other hand are mutually disposed so as to be rotationally symmetrical, the corresponding rotational axis of symmetry being an axis which, so as to be centric in the housing, is parallel to an output rotation axis of the first pear mechanism and/or the second gear mechanism.

2. The tandem drive device according to claim 1 ,
wherein the common control circuit is integrated in a controller board.

3. The tandem drive device according to claim 1 ,
further comprising a common electronics system cover.

4. The tandem drive device according to claim 1 ,
wherein the common housing, at least when viewed in a lateral view, is configured so as to be at least substantially quadrangular.

5. The tandem drive device according to claim 1 ,
comprising only one vehicle-interface apparatus plug connector.

6. The tandem drive device according claim 1 ,
wherein at least the first gear mechanism and the second gear mechanism are mutually disposed so as to be axially symmetrical.

7. The tandem drive device according to claim 1 ,
wherein the first gear mechanism and the second gear mechanism do not overlap in an axial direction defined by a rotation axis of the first drive motor.

8. The tandem drive device according to claim 1 ,
wherein a rotating direction of the first drive motor is counter to a rotating direction of the second drive motor.

9. A sliding roof system comprising a sliding roof system and a tandem drive device according to claim 1 .

10. The sliding roof system according to claim 9 further comprising a motor vehicle.

11. The tandem drive device according to claim 1 , wherein the common control is integrated in a substantially rectangular controller board.

12. The tandem drive device according to claim 1 , wherein the common housing, at least when viewed in a lateral view, is configured so as to be at least substantially rectangular.

13. The tandem drive device according claim 1 wherein the first drive system and the second drive system are mutually disposed so as to be axially symmetrical.

14. The sliding roof system of claim 9 , wherein the at least two sliding roof elements comprise a glass roof and a roller shutter.
