The invention relates to the technical field of hybrid power gearboxes, in particular to an engine three-gear driven hybrid power gearbox which comprises an engine with a shock absorber, a generator, a driving motor three-power source and an electric control system for controlling the three-power source and a gearbox to work. The gear clutch transmission system is connected with the three power sources and transmits the power of the three power sources, and the switching of power transmission paths and the switching of three gears driven by an engine are realized through the opening and closing control of a clutch in the gear clutch transmission system; the gear clutch transmission system comprises a generator power generation system, a driving motor pure electric driving system and an engine three-gear driving system. On one hand, efficient driving of the engine is achieved within more vehicle speed ranges; and on the other hand, the functions of engine starting and stopping, parking power generation, pure electric driving, range extending driving, engine three-gear direct driving, engine three-gear hybrid power and the like are achieved, finally, the fuel economy of the vehicle is improved, and the requirements of emission regulations are met.
