The invention discloses a dual-motor hybrid power gearbox which comprises an engine, a main driving motor, an auxiliary driving motor, a planet row, a parking clutch and an engine lock-up clutch. An outer gear ring of the planet row is connected with a main driving motor and an output shaft through gear meshing, a planet carrier of the planet row is connected with the engine, a sun gear of the planet row is connected with the auxiliary driving motor, the auxiliary driving motor is an ISG motor, an input shaft of the main driving motor is connected with the output shaft through gear meshing, and the output shaft is connected with a differential through gear meshing. A parking clutch is arranged on an outer gear ring of the planet row, and the parking clutch locks the outer gear ring of the planet row to meet the vehicle parking requirement. The engine lock-up clutch is arranged on the planet carrier of the planet row and the engine input shaft, and the engine lock-up clutch locks the planet carrier of the planet row and the engine input shaft to achieve the engine lock-up function. The gearbox has the advantages of being reliable in work, low in energy efficiency, compact in structure and low in cost.
