The invention provides a gearbox, a hybrid power system and an automobile. The gearbox comprises a shell, a speed change mechanism, a first main shaft, a second main shaft and a third main shaft. The first main shaft, the second main shaft and the third main shaft are movably inserted into the shell, the first main shaft and the second main shaft are coaxially distributed at intervals, the second main shaft is parallel to the third main shaft, the first main shaft is used for being in transmission connection with a first power source, the second main shaft is in transmission connection with the third main shaft, and the third main shaft is used for being in transmission connection with wheels; the speed change mechanism comprises a center wheel, a plurality of planet wheels, a planet carrier, a gear ring and a brake, 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, the planet carrier is coaxially connected with the first main shaft, the center wheel is used for being in transmission connection with a second power source, and the brake is used for braking the center wheel. And the gear ring is coaxially connected with the second main shaft. The motor can be prevented from being dragged, the structure of the gearbox is simplified, and the cost is reduced.
