The invention relates to an integrated oil cooling hub speed reduction electric wheel which comprises a motor, a planetary gear speed reducer and a bearing system which are arranged in the axial direction, and the planetary gear speed reducer is arranged in the motor and integrated with a brake. The bearing system comprises a rotor supporting bearing used for supporting a motor rotating system and a hub bearing used for supporting a wheel rotating system, the motor, the planetary gear reducer and the rotor supporting bearing are designed in an integrated oil cooling mode, and cavities where the motor, the planetary gear reducer and the rotor supporting bearing are located are communicated with one another. Cooling liquid cools and lubricates the motor, the planetary gear reducer and the rotor supporting bearing at the same time. Compared with the prior art, the electric wheel is compact in structure, the number of sealing pieces of the electric wheel can be reduced on the premise that the electric wheel has good structural rigidity, the axial size of an electric wheel assembly is reduced, and the electric wheel has the advantages of being good in cooling effect and easy to maintain.
