The invention relates to a speed reducer, a power driving assembly and a vehicle. The speed reducer comprises an input shaft; the first intermediate shaft is connected with the input shaft through a first transmission gear set and is provided with a first clutch; the second intermediate shaft is provided with a second clutch, and the second intermediate shaft and the first intermediate shaft are selectively connected through a second transmission gear set and a third transmission gear set; the output shaft is connected with the second intermediate shaft through a fourth transmission gear set; the speed reducer is provided with a first gear, the first clutch is disconnected, the second clutch is connected, and power of the driving motor is transmitted to wheels through the input shaft, the first transmission gear set, the first intermediate shaft, the second transmission gear set, the second intermediate shaft, the fourth transmission gear set and the output shaft. And at the second gear, the first clutch is connected, the second clutch is disconnected, and the power of the driving motor is transmitted to the wheels through the input shaft, the first transmission gear set, the first intermediate shaft, the third transmission gear set, the second intermediate shaft, the fourth transmission gear set and the output shaft.
