Abstract

A hydraulic power system is provided, which may include a source component configured to generate an electrical current and a receiving component configured to receive the electrical current generated by the source component. The system may further include at least one hydraulic hose having one or more embedded electrically conductive members being configured to carry the electrical current between the source component and the receiving component.

Claims

1. A hydraulic power system, comprising:

a source component configured to generate an electrical current;

a receiving component configured to receive the electrical current generated by the source component; and

at least one hydraulic hose having one or more embedded electrically conductive members being configured to carry the electrical current between the source component and the receiving component.

2. The system of claim 1, wherein the electrical current includes a control signal.

3. The system of claim 2, further including a hydraulically operated component associated with at least one of the source component and the receiving component, the hydraulically operated component being responsive to the control signal.

4. The system of claim 3, wherein the hydraulically operated component includes a work implement.

5. The system of claim 4, wherein the control signal includes work implement movement command information.

6. The system of claim 1, wherein the electrical current includes a communications signal.

7. The system of claim 6, wherein the communications signal includes information about a hydraulically operated component with which at least one of the source component and the receiving component is associated.

8. The system of claim 7, wherein the hydraulically operated component includes a work implement and the information includes at least one of work implement identification, size, operating capabilities, operating instructions, location, maintenance information, rental information, user identification, and hours of operation.

9. The system of claim 1, wherein the electrical current includes electrical power to operate the receiving component.

10. The system of claim 1, wherein the one or more electrically conductive members includes more than one isolated electrical conductor, the system being configured to transmit the electrical current from the source component to the receiving component via one of the isolated electrical conductors and back to the source component via another of the isolated electrical conductors.

11. The system of claim 1, wherein the electrical current is delivered from the source component to the receiving component via the one or more embedded electrically conductive members in the at least one hydraulic hose and grounded via a chassis ground.

12. The system of claim 1, wherein the one or more embedded electrically conductive members includes reinforcement braiding within the at least one hydraulic hose.

13. The system of claim 1, wherein at least one of the source component and the receiving component is electrically connected to the at least one hydraulic hose by an electrical connection integral with a hydraulic hose fitting attached to an end of the at least one hydraulic hose.

14. The system of claim 1, wherein at least one of the source component and the receiving component is electrically connected to the at least one hydraulic hose by a contact ring in contact with the one or more embedded electrically conductive members.

15. The system of claim 1, wherein the receiving component is associated with a memory device configured to store information transmitted from the source component.

16. The system of claim 1, wherein each of a first end and a second end of the at least one hydraulic hose are associated with both a source component and a receiving component, the system being configured to transfer information from the first end to the second end and from the second end to the first end.

17. A work machine having a hydraulic power system, comprising:

a frame;

a power source attached to the frame;

a hydraulically operated component;

a hydraulic pump powered by the power source and configured to pump hydraulic fluid to the hydraulically operated component;

at least one hydraulic hose configured to carry the hydraulic fluid from the hydraulic pump to the hydraulically operated component;

a source component attached to the frame and configured to generate an electrical current; and

a receiving component associated with the hydraulically operated component and configured to receive the electrical current generated by the source component;

the hydraulic hose having one or more embedded electrically conductive members configured to carry the electrical current between the source component and the receiving component.

18. The work machine of claim 17, wherein the electrical current includes at least one of a control signal, a communications signal, and electrical power.

19. The work machine of claim 17, wherein the one or more electrically conductive members includes more than one isolated electrical conductor, the system being configured to transmit the electrical current from the source component to the receiving component via one of the isolated electrical conductors and back to the source component via another of the isolated electrical conductors.

20. The work machine of claim 17, wherein the electrical current is delivered from the source component to the receiving component via the one or more embedded electrically conductive members in the at least one hydraulic hose and grounded via a chassis ground.

21. The work machine of claim 17, wherein the one or more embedded electrically conductive members includes reinforcement braiding within the at least one hydraulic hose.
