An integrated electric wheel with a cooling function comprises a hub motor with a cooling water channel, a planetary reducer connected with a rotating shaft of the hub motor, a hub connected with the output end of the planetary reducer and a brake fixed to the hub, and is characterized in that the cooling water channel in the hub motor extends forwards to the periphery of the planetary reducer; and the planetary reducer is circularly cooled, and an oil guide assembly for collecting oil liquid thrown out in the circumferential direction and conducting lubricating and heat dissipation on the planetary reducer is assembled on the planetary reducer. Lubricating and radiating efficiency of parts close to the center of the speed reducer is effectively improved, temperature rise and part abrasion in the speed reducer are slowed down, the probability of abnormal transmission caused by bearing sintering and gear abrasion due to high temperature is effectively reduced, transmission reliability of the planetary speed reducer is improved, and the service life of the planetary speed reducer is prolonged. Integrated optimization of multiple structures of the electric wheel is formed, the integration degree is improved, whole vehicle arrangement is facilitated, the power density of the electric wheel is improved, and the cruising ability of the electric wheel is improved.
