The invention discloses an electric wheel used for an electric-drive dump truck. The electric wheel comprises a reduction gear box and an electric wheel motor base, an inner toothed ring is arranged at the outer side of a motor base journal of the electric wheel motor base, and a motor is arranged in an inner hole of the motor base journal of the electric wheel motor base; an oil return opening is formed in a motor base flange of the electric wheel motor base, the oil return opening is communicated with an inner chamber of the inner toothed ring, an oil return pipe hole is formed in the box wall of the reduction gear box, an oil return pipe is arranged in the oil return pipe hole, one end of the oil return pipe is communicated with the oil return opening, and the other end of the oil return pipe is communicated with an inner chamber of the reduction gear box; a fixed supporting sleeve is arranged on the inner wall of the reduction gear box, the fixed supporting sleeve is in sealed connection with the inner wall of the reduction gear box through welding lines, and the oil return pipe is located inside the fixed supporting sleeve; the oil return pipe is sleeved with an oil return pipe sleeve, the oil return pipe sleeve is made of elastomeric materials, one end of the an oil return pipe sleeve is closely attached to the oil return pipe, and the other end of the an oil return pipe sleeve is arranged on the fixed supporting sleeve in a sleeving mode. By means of the oil return opening structure of the electric wheel, vibration generated while a gear train and the motor work can be reduced, and leakage of gear lubricating oil can be avoided.
