The invention provides a gearbox special for a hybrid electric vehicle and the hybrid electric vehicle comprising the gearbox. The gearbox comprises an engine, a driving motor, a generator, a planetary gear set, a clutch, a differential mechanism, a speed reducer, an input outer shaft and an input inner shaft. The generator is arranged between the planetary gear set and the clutch, and the driving motor is arranged between the clutch and the engine. The first end of the input outer shaft is fixedly connected with the driving motor, the second end of the input outer shaft extends towards the engine, and the driving motor is fixedly connected with the input outer shaft; the first end of the input inner shaft is fixedly connected to the planetary gear set, and the second end of the input inner shaft sequentially penetrates through the generator rotor, the clutch and the driving motor rotor and then is connected with the engine. The speed reducer is connected to the input outer shaft between the driving motor and the engine, and the differential mechanism is fixedly connected with the speed reducer. By the adoption of the gearbox, coaxial arrangement of the two motors can be achieved, the axial space is saved, and meanwhile the problem that bearings between the inner shaft and the outer shaft are poor in lubrication can be effectively solved.
