  "textContent": "A wheel hub driving system, including a housing, an electric motor, two planetary gear sets and a wheel hub bearing. The wheel hub bearing has a middle axle and an outer ring, the middle axle is fixed relative to the housing, and both a primary sun gear and a secondary sun gear are sleeved around the periphery of the wheel hub bearing. A stator of the electric motor, a primary geared ring and a secondary geared ring are all fixed to the housing. A rotor of the electric motor is anti-torsionally connected to the primary sun gear. A primary planet carrier is anti-torsionally connected to the secondary sun gear, a secondary planet carrier is anti-torsionally connected to the outer ring and the outer ring is configured to be anti-torsionally connected to a wheel rim so as to transmit power from the electric motor to the wheel rim.",
