The invention discloses a wheel hub motor and an electric vehicle, the wheel hub motor comprises a middle shaft, and a shell assembly, a stator assembly, a rotor assembly and a gear assembly which are connected to the middle shaft, the shell assembly and the rotor assembly are supported on the middle shaft through bearings, the shell assembly is provided with a main shell, the rotor assembly is in transmission connection with the shell assembly through the gear assembly, the rotor assembly is provided with a first check ring facing the main shell, the main shell is provided with a second check ring facing the rotor assembly, the first check ring and the second check ring are at least partially staggered in the axial direction of the center shaft, a grease sealing cavity is formed between the rotor assembly and the main shell, and the gear assembly is located in the grease sealing cavity. The surface of the gear assembly is coated with lubricating grease, the first check ring of the rotor assembly and the second check ring of the main shell are staggered in the axial direction, the lubricating grease can be prevented from being thrown out of the grease sealing cavity and remaining in the grease sealing cavity, the lubricating effect is improved, the reliability problems of abrasion, failure and the like of the gear assembly are solved, and the operation reliability of the hub motor is improved.

    本发明公开了一种轮毂电机及电动车,轮毂电机包括中轴以及连接于中轴的壳体组件、定子组件、转子组件以及齿轮组件,壳体组件和转子组件通过轴承支撑在所中轴上,壳体组件具有主壳体,其中,转子组件与壳体组件通过齿轮组件传动连接,转子组件设置有朝向主壳体的第一挡圈,主壳体设置有朝向转子组件的第二挡圈,沿中轴的轴向,第一挡圈和第二挡圈至少部分交错,转子组件和主壳体之间形成封脂腔,齿轮组件位于封脂腔内。齿轮组件的表面涂覆润滑脂,转子组件的第一挡圈与主壳体的第二挡圈在轴向上交错,能够防止润滑脂被甩出封脂腔,润滑脂留在封脂腔内,提升润滑效果,避免齿轮组件发生磨损、失效等可靠性问题,提高轮毂电机的运行可靠性。
