The invention discloses a wheel motor driving system of a commercial electric vehicle. The wheel motor driving system comprises a sun gear and a planetary gear which are arranged between a driving motor and a wheel and are meshed each other, wherein the driving motor is connected with the sun gear; the planetary gear is connected with the wheel; the sun gear is driven by the driving motor to rotate; the wheel is driven by the planetary gear to rotate; the planetary gear is connected the wheel through a planet carrier; a gear ring is mounted at the outer part of the planet carrier; a brake is arranged between the planet carrier and the wheel; the planet carrier is driven by the wheel to rotate; the planetary gear is driven by the planet carrier to rotate; the sun gear is driven by the planetary gear to rotate; the driving motor is inversely dragged by the sun gear to generate electricity. According to the wheel motor driving system disclosed by the invention, the planetary gear is a duplicate gear, and a planetary mechanism is arranged between the driving motor and the wheel; through the transmission of the planetary gear, the transmission with a high speed ratio and large torque is realized; through the adoption of the duplicate gear, the size of the planetary gear is reduced.
