The invention provides a wheel edge driving system which is suitable for a new energy vehicle, the wheel edge driving system comprises a permanent magnet synchronous motor, a planetary reducer and a wheel, the permanent magnet synchronous motor is arranged on the inner side of a rim of the wheel, and the planetary reducer is arranged on the inner side of the rim of the wheel. The two ends of a knuckle shaft of the permanent magnet synchronous motor are installed on an inner side radial plate and an outer side radial plate of the wheel through two bearings respectively, and a rotor of the permanent magnet synchronous motor further serves as a sun gear of the planetary reducer and is connected with a planet gear of the planetary reducer in a meshed mode. The planet gear is installed on a planet carrier of the planetary reducer through a pin shaft, and the planet carrier is connected with the steering knuckle shaft through a spline.
