The invention discloses an integrated hub motor driving unit which has the functions of driving, speed reducing, braking and supporting and is compact in structure due to the fact that all components are integrated in a wheel. According to the integrated hub motor driving unit, a driving motor, a two-stage planet reducing mechanism, a braking disc, a brake and the like are applied to the interior of the wheel, traditional automobile components of a speed reducer, a transmission shaft and the like are omitted through the high-integration structure, the finished automobile mass is greatly lowered, the transmission efficiency is improved, and the reduced weight can be used for greatly increasing the capacity of a storage battery. Furthermore, the motor passes through the two-stage planet reducing mechanism and then achieves large-torque output, and the dynamic property and the economical efficiency of a finished automobile are greatly improved; meanwhile, various hybrid electric automobile types or pure electric automobile types can be matched according to different demands, and the application range is very wide.
