The invention relates to the technical field of hybrid power gearboxes, in particular to a hybrid power gearbox which comprises a generator, an engine, a driving motor, three power sources and a gear clutch transmission system which is connected with the three power sources, transmits power of the three power sources and achieves power generation and driving. The cooling and lubricating system is used for cooling and lubricating the two motors and the gear clutch transmission system; the gear clutch transmission system comprises a power generation system, a driving motor pure electric driving system and an engine single-gear or multi-gear driving system, and the cooling and lubricating system comprises a suction filtration and electronic oil pump, an oil cooler and a cooling and lubricating oil way. On one hand, the gearbox is simpler in structure and lower in manufacturing cost due to the introduction of the electromagnetic clutch, and on the other hand, one-gear, second-gear and third-gear driving and range-extending driving multi-variety hybrid power gearboxes of the engine can be developed on the same platform by increasing and decreasing the number of gears of the engine driving system and the electromagnetic clutch.
