The invention relates to a magnetic dynamic seal outer rotor hub motor structure. The magnetic dynamic seal outer rotor hub motor structure comprises an outer rotor shell which is coaxially and fixedly connected with a rim, wherein the outer rotor shell is connected with a rotor cover plate installed on an outer ring of a hub bearing, a magnetic sealing ring is arranged between the rotor cover plate and a steering knuckle flange installed on an inner ring of the hub bearing and at the position close to an automobile suspension, and a stator support coaxially and fixedly connected with the steering knuckle flange is installed in the outer rotor shell. Compared with the prior art, and according to the invention, the outer rotor shell is coaxially and fixedly connected with the rim, an electronic component and a water-cooled jacket are integrally installed on the stator support, and a wire harness and the cooling water pipe are led out via the steering knuckle flange of the hollow structure, so that the integrated degree of the whole hub motor is improved. In addition, the magnetic sealing ring is arranged at the position, close to an automobile suspension, between the rotor cover plate and the steering knuckle flange, so that the dynamic sealing of the hub bearing can be effectively achieved.
本发明涉及一种磁力动密封外转子轮毂电机结构,包括与轮辋同轴固联的外转子壳体,其中,外转子壳体连接有安装在轮毂轴承外圈上的转子盖板,转子盖板与安装在轮毂轴承内圈的转向节法兰之间、靠近汽车悬架的位置设有磁力密封圈,外转子壳体内安装有与转向节法兰同轴固联的定子支架。与现有技术相比,本发明通过将外转子壳体与轮辋同轴固联,在定子支架上集成安装电子元器件和水冷套,并通过中空结构的转向节法兰引出线束和冷却水管,提高了整个轮毂电机的集成程度,此外,本发明在转子盖板与转向节法兰之间靠近汽车悬架的位置设置磁力密封圈,能够有效实现轮毂轴承的动密封。
