The electric vehicle hub comprises a rim and a magnetic conductive ring body, the rim is arranged on the outer side of the magnetic conductive ring body in a sleeving mode, the two axial end faces of the magnetic conductive ring body are turned outwards to form end structures, the magnetic conductive ring body further comprises a middle section located between the two end structures, and the middle section is located between the two end structures. An installation plane is formed on the inner side face of the rim, the diameter of the installation plane is smaller than the outer diameter of the end structure, and the installation plane makes contact with the outer side face of the middle section. Compared with the prior art, the threaded mounting hole is located in the end structure formed by outward rolling of the magnetic conductive ring body, on the premise that the forming process and the mounting and fastening function of the threaded mounting hole are guaranteed, the radial thickness of the magnetic conductive ring body is reduced, light weight and weight reduction of the magnetic conductive ring body are achieved, and weight reduction of motor parts is achieved; and meanwhile, the material of the magnetic conductive ring body is saved, and the cost of motor finished products is reduced.

    本发明涉及一种导磁环两端面外翻的电动车用轮毂,包括轮辋和导磁环本体,所述轮辋套设于所述导磁环本体的外侧,所述导磁环本体轴向的两端面向外翻卷形成端部结构,所述导磁环本体还包括位于两所述端部结构之间的中间段,轮辋的内侧面形成有安装平面,安装平面的直径小于端部结构的外径,安装平面和中间段的外侧面相接触。与现有技术相比,本发明中螺纹安装孔位于导磁环本体向外翻卷形成的端部结构上,在保证螺纹安装孔的成型工艺和安装紧固功能的前提下,减少了导磁环本体的径向厚度,实现导磁环本体的轻量化减重,实现了电机零部件的减重,同时节约了导磁环本体材料,实现了电机成品降本。
