Abstract

A device for actuating components of a motor vehicle has at least two electric motors, each of which has at least one stator unit and one rotor unit, and a control device for the electric motors, which has at least one logic device and one power device. The control device is fixedly connected to at least one component of both electric motors.

Claims

1. A device for actuating components of a motor vehicle comprising:

a first electric motors having at least one first stator unit and one first rotor unit;

a second electric motor having at least one second stator unit and one second rotor unit; and

a control device for the first and second electric motors, the control device having at least one logic device and one power device, the control device being fixedly connected to at least one component of the first and second electric motors.

2. The device as recited in claim 1 further comprising a shared housing, the control device and the first and second electric motors being accommodated in the shared housing.

3. The device as recited in claim 1 further comprising a system logic device fixedly connected to at least one component of the first and second electric motors.

4. The device as recited in claim 1 wherein the control device is fixedly connected to the first stator unit of the first electric motor.

5. The device as recited in claim 4 wherein the control device is fixedly connected to the second stator unit.

6. The device as recited in claim 1 wherein the control device includes at least one power device.

7. The device as recited in claim 1 wherein the at least one power device includes a plurality of power devices having an identical design.

8. The device as recited in claim 3 wherein the control device is in contact with the system logic device.

9. The device as recited in claim 1 wherein the contact between the control device and the system logic device is implemented via surface contacts.

10. The device as recited in claim 3 further comprising a shared cooling device, the system logic device and the control device being situated on the shared cooling device.

11. The device as recited in claim 10 wherein the cooling device is in direct contact with heat-conducting elements of the system logic device.

12. The device as recited in claim 3 wherein the system logic device has a flat design.

13. The device as recited in claim 10 wherein the shared cooling device has surface contacts to the control device.

14. The device as recited in claim 3 further comprising a connecting device, the control device and the system logic device being connected to the first and second electric motors via the connecting device.

15. The device as recited in claim 14 wherein the connecting device has one motor shield for each of the first and second electric motors.

16. The device as recited in claim 15 wherein the motor shields are connected to one another to form one piece.

17. The device as recited in claim 15 wherein the first and second stator units are situated on the motor shields.

18. The device as recited in claim 15 further comprising sensor units situated on the motor shields.

19. The device as recited in claim 1 wherein the control device controls additional electric motors additional to the first and second electric motors.

20. The device as recited in claim 2 wherein the shared housing includes an injection molded-element.

21. The device as recited in claim 1 wherein the first and second rotor devices are fixedly connected to the mechanical power transmission devices.

22. A method for actuating a component using the actuating device as recited in claim 1, the method comprising:

actuating a component selected from a group of components including gear transmission systems and camshaft adjustment systems.

23. A method for manufacturing an actuating device for components of a motor vehicle comprising the steps of:

connecting at least one component of at least two electric motors to a control device to form a module; and

sheathing or encapsulating the module in plastic.

24. The method as recited in claim 23 wherein the components of the at least two electric motors are connected to the control device via a connecting device.

25. The method as recited in claim 23 wherein the component of the electric motors is a stator unit.

26. The method as recited in claim 23 further comprising at least one sensor device or wherein at least one plug connector is connected to the control device.
