The invention provides a hybrid power system of a crane, a control method, a virtual device and the crane. The system is characterized in that the output end of an engine is connected with the input end of a gearbox; one end of the power takeoff is connected with one output end of the gearbox, and the other end of the power takeoff is connected with the input end of the driving motor; the output end of the driving motor is connected with the multi-union oil pump; the central controller is respectively connected with the engine and the hybrid controller; the hybrid controller is respectively connected with the driving motor and the power source; the engine, the gearbox, the power takeoff, the driving motor and the multi-union oil pump are connected to form a first hydraulic passage which is used for providing power for loading operation of the crane; the power source, the driving motor and the multi-union oil pump are connected to form a second hydraulic passage which is used for providing power for loading operation of the crane. The driving motor and the output shaft of the power takeoff are integrally designed, so that the output shaft can be driven by a motor stator and can also be driven by an engine, and the power distribution of the hybrid power system is optimized.

    本发明提供一种起重机的混合动力系统、控制方法、虚拟装置及起重机,系统包括发动机的输出端和变速箱的输入端连接;取力器一端与变速箱的一个输出端连接,取力器另一端与驱动电机的输入端连接;驱动电机输出端与多联油泵连接;中央控制器分别与发动机和混合控制器连接;混合控制器分别与驱动电机和动力源连接;其中,发动机、变速箱、取力器、驱动电机和多联油泵连接形成,用于为起重机的上车作业提供动力的第一液力通路;动力源、驱动电机和多联油泵连接形成,用于为起重机的上车作业提供动力的第二液力通路。本发明通过将驱动电机和取力器的输出轴集成设计,使得输出轴既可通过电机定子驱动,也可通过发动机驱动,优化了混合动力系统功率分配。
