Abstract:
A hybrid power system and an operation machine. The hybrid power system comprises an engine, a power distribution device, and a double-shaft extension motor; an input end of the power distribution device is connected to an output end of the engine, a first power output end of the power distribution device is connected to one end of a driving shaft, and the input end is connected to the first power output end; a second power output end of the power distribution device is connected to one end of the double-shaft extension motor, and the second power output end is selectively coupled with or separated from the input end; the other end of the double-shaft extension motor is configured to be connected to a hydraulic power system; the power distribution device has a power coupling state and a separation state; in the power coupling state, the first power output end and the second power output end form power coupling connection; and in the separation state, the input end is separated from the second power output end. The working state of the power distribution device is changed, such that the power of the hybrid power system can be conveniently distributed according to needs.
