Abstract

A hydraulic supply system for at least one vehicle, in particular a rail vehicle, includes at least one drive motor, at least one flange, at least one hydraulic pump and at least one control plate for receiving and/or controlling further electrical and/or hydraulic components of the hydraulic supply system, wherein, in the mounted state, the flange is secured on the drive motor and on the hydraulic pump for the mutual mechanical coupling thereof, and wherein the flange is secured on the control plate, wherein the flange also has at least one connector for coupling the hydraulic pump to the control plate, and wherein the flange has at least one electrical coupling element for electrically coupling the drive motor to the control plate.

First claim

The invention claimed is:

1. A hydraulic supply system for at least one rail vehicle, the system comprising:
at least one drive motor;
at least one flange;
at least one hydraulic pump; and
at least one control plate for receiving and/or controlling further electrical and/or hydraulic components of the hydraulic supply system,
wherein the flange, in a mounted state, is fastened to the drive motor and to the hydraulic pump for the mutual mechanical coupling thereof,
wherein the flange is fastened to the control plate, wherein the flange further has at least one connector for the coupling of the hydraulic pump with the control plate,
wherein the flange has at least one electrical coupling element for the electrical coupling of the drive motor with the control plate, and
wherein the connector is at least one hydraulic line and/or at least one hydraulic bore.

2. The hydraulic supply system of claim 1 , wherein the flange is an integral part of the drive motor, wherein at least one mechanical receiver for the hydraulic pump is formed by the flange.

3. The hydraulic supply system of claim 1 , wherein the electrical coupling element is at least one flange cable feedthrough and/or at least one flange cable duct.

4. The hydraulic supply system of claim 1 , wherein the flange has at least one flange housing in which the electrical coupling element and/or the connector are integrated.

5. The hydraulic supply system of claim 1 , wherein the hydraulic supply system has at least one control and/or regulating device which, in a mounted state, is electrically connected by the control plate and/or the electrical coupling element to the drive motor.

6. The hydraulic supply system of claim 1 , wherein the drive motor and the hydraulic pump in a fastened state are mechanically fastened by the flange to at least one face of the control plate.

7. The hydraulic supply system of claim 1 , wherein the flange has at least one shaft tunnel in which an end of at least one motor shaft of the drive motor and an end of at least one pump shaft of the hydraulic pump are coupled in a rotationally fixed manner by at least one coupling.

8. The hydraulic supply system of claim 7 , wherein the at least one bearing device for supporting the motor shaft is arranged in the flange.

9. The hydraulic supply system of claim 1 , wherein, in a mounted state, at least a first seal is arranged between the flange and the hydraulic pump and/or at least a second seal is arranged between the flange and the control plate.

10. The hydraulic supply system of claim 1 , further comprising at least one hydraulic tank in which, in a mounted state, the drive motor and the flange as well as the hydraulic pump are arranged.

11. The hydraulic supply system of claim 1 , wherein the flange has at least one further hydraulic line and/or at least one further hydraulic bore by which the hydraulic tank and the control plate are connected.

12. The hydraulic supply system of claim 1 , wherein the flange has at least one cooling body.

13. The hydraulic supply system of claim 1 , wherein the flange, in a mounted and operation-ready state, is arranged between the drive motor and the hydraulic pump.
