Working machine driving unit |
摘要 |
A driving device of a work machine includes a power generator adapted to be driven by an engine, and a power storage device for storing the electric power generated by the power generator. Electric motors and a motor generator, both adapted to be operated by electric power supplied from either one or both of the power generator and the power storage device respectively drive pumps and a pump motor. Supporting circuits for feeding supporting hydraulic oil are provided between a plurality of driving circuits that drive a plurality of hydraulic actuators of a working unit by oil hydraulics generated by the pumps and the pump motor. By enabling the plurality of driving circuits to effectively share excess energy, the invention makes possible a compact construction of a driving device of a work machine.
