CONTROLLER OF HYBRID CONSTRUCTION MACHINE |
摘要 |
A controller of a hybrid construction machine which can achieve minimization of a required number of sensors is provided. A sub pump driven by output of an electric motor is connected to discharge sides of main pumps. Proportional solenoid throttling valves are provided in connection process between the sub pump and the main pumps for controlling a flow rate supplied from the sub pump to the main pump. A control unit is provided for electrically controlling the openings of the proportional solenoid throttling valves. Pressure sensors are connected to the control unit which controls the openings of the proportional solenoid throttling valves in response to pressure signals from the pressure sensors.
