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.

    带冷却功能的集成型电动轮,包括带有冷却水道的轮毂电机、与轮毂电机的转轴连接的行星减速器、与行星减速器输出端连接的轮毂和与轮毂固定的制动器,其特征在于:轮毂电机中的冷却水道向前延伸至行星减速器外周,对行星减速器进行循环冷却,行星减速器上装配收集从圆周向甩出的油液并对行星减速器进行润滑散热的导油组件。本发明有效提高靠减速器中心位置部件的润滑散热效率,减缓减速器内的温升和部件磨损,有效降低高温造成轴承烧结、齿轮磨损传动异常的概率,提高行星减速器的传动可靠性,并延长行星减速器的使用寿命,形成对电动轮多处结构的集成优化,提高集成度,有利于整车布置,提升电动轮的功率密度,以提高其续航能力。
