CONSTRUCTION MACHINE ENERGY REGENERATION APPARATUS |
| 摘要 |
A construction machine energy regeneration apparatus includes: a movable weight provided in a construction machine and movable vertically; and a power-transmitting hydraulic circuit, which moves the movable weight upward by utilizing energy that is generated when a boom, an arm, or a bucket moves in a gravitational direction or energy that is generated when a brake is applied to bring a turning unit or a running unit to a stop, and utilizes potential energy of the movable weight as energy for driving the boom or the arm. |

1. A construction machine energy regeneration apparatus of a construction machine, the construction machine including a first operating part and a second operating part, which are driven by a hydraulic fluid, the first operating part including a boom, a turning unit, or a running unit, the second operating part including an arm, a bucket, or an engine-assisting hydraulic motor, the construction machine energy regeneration apparatus comprising:
a movable weight provided in the construction machine and movable vertically; and a power-transmitting hydraulic circuit, which moves the movable weight upward by utilizing energy that is generated when the boom, the arm, or the bucket moves in a gravitational direction or energy that is generated when a brake is applied to bring the turning unit or the running unit to a stop, and utilizes potential energy of the movable weight as energy for driving the first operating part or the second operating part. |
