Power system of multifunctional hybrid excavator and control method
The invention discloses a power system of a multifunctional hybrid excavator and a control method, an engine is coupled with a generator/driving motor device, the engine is in transmission connection with the generator/driving motor device through an electromagnetic clutch, and an output shaft of the generator/driving motor coupling device is in transmission connection with a working pump; the first hydraulic output end and the second hydraulic output end of the working pump are connected with the hydraulic input end of the pilot pump and the hydraulic input end of the multi-way valve respectively, and the hydraulic output end of the multi-way valve is used for being connected with the hydraulic input ends of a bucket oil cylinder, a bucket rod oil cylinder, a movable arm oil cylinder, a left walking motor and a right walking motor respectively. The energy storage device is in circuit connection with the generator and the rotary motor. Through the working mode of hybrid power, the engine and the motor can provide power for the whole excavator at the same time, excess energy is stored and utilized, the mode that electric energy, mechanical energy or hydraulic pressure are combined to drive different workpieces to act is adopted, and energy consumption of daily commuting of the excavator is reduced.
本发明公开一种多功能混动挖掘机的动力系统及控制方法，发动机与发电机/驱动电机装置耦合设置，发动机通过电磁离合器与发电机/驱动电机装置传动连接，发电机/驱动电机耦合装置的输出轴与工作泵传动连接，工作泵的第一液压输出端、第二液压输出端分别与先导泵的液压输入端、多路阀的液压输入端连接，多路阀的液压输出端用于分别与铲斗油缸、斗杆油缸、动臂油缸、左行走马达、右行走马达的液压输入端连接，储能装置分别与发电机、回转电机电路连接。本发明通过混合动力的工作方式，可由发动机和电机同时为整机提供动力，并且实现多余能量存储利用，采用电能机械能或液压结合驱动不同工件动作的方式，减少挖掘机日常通勤的能耗。
