The invention provides a gearbox, a hybrid power system and an automobile. The gearbox comprises a shell, a speed change mechanism, a first clutch, a second clutch, a first main shaft and a second main shaft. The first main shaft and the second main shaft are movably inserted into the shell, and the first main shaft and the second main shaft are spaced in parallel; the speed change mechanism comprises a center wheel, a plurality of planet wheels, a planet carrier, a gear ring, a first clutch and a second clutch, the gear ring and the center wheel are coaxially arranged, the planet wheels are located between the center wheel and the gear ring and are all meshed with the center wheel and the gear ring, and the first clutch is located on the first main shaft and divides the first main shaft into a first section and a second section; the first section is in transmission connection with the gear ring and used for being in transmission connection with a power source, the second section is in transmission connection with the center wheel, the planet carrier coaxially sleeves the second main shaft, and the second clutch is located on the second main shaft and is in transmission connection with the second main shaft and the gear ring. The motor can be prevented from being dragged, and the structure of the gearbox is simplified.
