The invention discloses a hub electric driving system, a driving wheel and a vehicle. According to the hub electric driving system for the vehicle, the hub electric driving system is arranged in a hubof the driving wheel of the vehicle, and the hub electric driving system comprises a motor and a hub speed reducer, wherein the hub speed reducer comprises a small planetary gear train and a large planetary gear train, and the small planetary gear train comprises a small sun gear, a minor planet carrier and a small gear ring; the large planetary gear train comprises a large sun gear, a large planet carrier and a large gear ring; and the small planetary gear train and the large planetary gear train are coaxially and radially arranged, and the power input end of the large planetary gear train and the power output end of the small planetary gear train are at least partially overlapped in the radial direction. The hub electric drive system is compact in structure and small in axial size, andthe requirements for the large transmission ratio and the large torque can be met.
