The invention provides a hybrid power system for a working machine and the working machine. The hybrid power system comprises a power switching device, wherein the power switching device comprises an input end, a first output end and a second output end, and the first output end and the second output end are both selectively connected with the input end of the power switching device; a power source which comprises an engine and a motor connected with the engine, wherein the output end of the power source is in dynamic coupling connection with the input end of the power switching device; a driving shaft which is in power coupling connection with the first output end, wherein the driving shaft is used for driving the chassis to run; and a hydraulic pump which is in power coupling connection with the second output end. According to the hybrid power system, the motor is connected with the engine, hybrid power output can be conveniently achieved, switching of multiple power modes can be conveniently achieved through switching of the power switching device, in this way, an operation machine can operate in the multiple modes according to requirements, and the energy efficiency in the multiple modes is higher.

    本发明提供一种作业机械的混合动力系统和作业机械,该混合动力系统包括:动力切换装置,动力切换装置包括输入端、第一输出端和第二输出端,第一输出端和第二输出端均与动力切换装置的输入端可选择性地接合;动力源,动力源包括发动机和与发动机连接的电机,动力源的输出端与动力切换装置的输入端动力耦合连接;驱动轴,驱动轴与第一输出端动力耦合连接,所述驱动轴用于驱动底盘行驶;液压泵,液压泵与第二输出端动力耦合连接。本发明的混合动力系统,通过将电机与发动机连接,可以方便地实现混合动力输出,且通过动力切换装置的切换,可以方便地实现多种动力模式的切换,这样作业机械可以根据需求在多种模式下作业,且各种模式下能效均较高。
