REGENERATIVE MACHINE COUPLING SYSTEM

摘要

A system includes a first machine having a first bail member and a first push bar, at first end. The first bail member includes a first hydraulic cylinder. A first hook and second push bar, at second end. The second push bar includes a second hydraulic cylinder in fluid communication with first hydraulic accumulator. The second machine having second bail member and first push bar, at first end. The second bail member includes third hydraulic cylinder in fluid communication with second hydraulic accumulator. A second hook and second push bar, at second end. The second push bar includes fourth hydraulic cylinder. The first hook coupled to second bail member and second push bar of first machine is in mechanical contact with first push bar of second machine. The impact energy generated at beginning of push operation and pull operation is stored in first hydraulic accumulator and second hydraulic accumulator respectively.

1. A system for recovering impact energy generated during at least one of a push operation and a pull operation between two or more machines operated in a worksite, the system comprising:
a first machine having:
a first bail member and a first push bar at a first end of the first machine, wherein the first bail member includes a first hydraulic cylinder; anda first hook and a second push bar at a second end of the first machine, wherein the second push bar includes a second hydraulic cylinder, the second hydraulic cylinder being in fluid communication with a first hydraulic accumulator; and a second machine having:
a second bail member and a first push bar at a first end of the second machine, wherein the second bail member includes a third hydraulic cylinder, the third hydraulic cylinder being in fluid communication with a second hydraulic accumulator; anda second hook and a second push bar at a second end of the second machine, wherein the second push bar includes a fourth hydraulic cylinder; wherein the first machine and the second machine are adapted to work in collaboration, such that the first hook of the first machine coupled to the second bail member of the second machine, and the second push bar of the first machine being in mechanical contact with the first push bar of the second machine; wherein the impact energy generated at a beginning of the push operation by the second machine may be captured by a regenerative coupling system, and stored in the first hydraulic accumulator; wherein the impact energy generated at a beginning of the pull operation by the first machine may be captured by a regenerative coupling system, and stored in the second hydraulic accumulator.
