Abstract

A plastic control plate for a gearbox control device of a hydraulic motor vehicle is disclosed, which comprises at least one channel (2a, 2b, 2c, 2d, 2e, 2f, 2′) extending in the plastic control plate (1) and is used to guide a cooling medium and a heat conducting body (3) which is at least partially integrated into the plastic control plate (1) and is arranged directly adjacent to the channel (2a, 2b, 2c, 2d, 2e, 2f, 2′).

Claims

1. A plastic control plate of a hydraulic gearbox control device in a motor vehicle, comprising

at least one channel which runs through the plastic control plate and is used for carrying a cooling medium, and

a heat conduction body which is at least partly integrated in the plastic control plate and is arranged directly adjacent to the channel.

2. The plastic control plate as claimed in claim 1, wherein the heat conduction body is a metal plate, in particular an aluminum plate.

3. The plastic control plate as claimed in claim 1, wherein the heat conduction body is designed in such a way that the cooling medium, in particular a hydraulic fluid, flows against it.

4. The plastic control plate as claimed in claim 1, wherein a flat area of the heat conduction body is designed as a wall area of the channel.

5. The plastic control plate as claimed in claim 1, wherein the heat conduction body is designed in the form of a U, wherein the inner sides of the U form wall areas of the channel.

6. The plastic control plate as claimed in claim 1, wherein the upper surface of the plastic control plate is flush with the upper surface of the heat conduction body.

7. An arrangement comprising a plastic control plate and a gearbox control electronics system, wherein the plastic control plate comprises:

at least one channel which runs through the plastic control plate and is used for carrying a cooling medium, and

a heat conduction body which is at least partly integrated in the plastic control plate and is arranged directly adjacent to the channel, and wherein the gearbox control electronics system, in particular a substrate carrying the electronic components of said system, is arranged directly on the upper surface of the heat conduction body.

8. The arrangement as claimed in claim 7, wherein the gearbox control electronics system is electrically contacted via an electrical circuit board, in particular a flexible circuit board.

9. The arrangement as claimed in claim 7, wherein the gearbox control electronics system is electrically contacted via a stamped-grid arrangement, which extends partly over the upper surface of the plastic control plate and partly over the upper surface of the heat conduction body.

10. The arrangement as claimed in claim 7, wherein the heat conduction body is a metal plate, in particular an aluminum plate.

11. The arrangement as claimed in claim 7, wherein the heat conduction body is designed in such a way that the cooling medium, in particular a hydraulic fluid, flows against it.

12. The arrangement as claimed in claim 7, wherein a flat area of the heat conduction body is designed as a wall area of the channel.

13. The arrangement as claimed in claim 7, wherein the heat conduction body is designed in the form of a U, wherein the inner sides of the U form wall areas of the channel.

14. The arrangement as claimed in claim 7, wherein the upper surface of the plastic control plate is flush with the upper surface of the heat conduction body.

15. A gearbox control system comprising:

a plastic control plate

at least one channel which runs through the plastic control plate for carrying a cooling medium,

a heat conduction body which is at least partly integrated in the plastic control plate and is arranged directly adjacent to the channel,

a gearbox control circuit arranged on a substrate which is arranged directly on the upper surface of the heat conduction body.

16. The gearbox control system as in claim 15, wherein the gearbox control circuit is electrically contacted via an electrical circuit board, in particular a flexible circuit board.

17. The gearbox control system as in claim 15, wherein the gearbox control system is electrically contacted via a stamped-grid arrangement, which extends partly over the upper surface of the plastic control plate and partly over the upper surface of the heat conduction body.

18. The gearbox control system as in claim 15, wherein the heat conduction body is a metal plate, in particular an aluminum plate.

19. The gearbox control system as in claim 15, wherein the heat conduction body is designed in such a way that the cooling medium, in particular a hydraulic fluid, flows against it.

20. The gearbox control system as in claim 15, wherein a flat area of the heat conduction body is designed as a wall area of the channel.

21. The gearbox control system as in claim 15, wherein the heat conduction body is designed in the form of a U, wherein the inner sides of the U form wall areas of the channel.

22. The gearbox control system as in claim 15, wherein the upper surface of the plastic control plate is flush with the upper surface of the heat conduction body.
