An electric motor includes a stator and a rotor movably disposed within the stator to define a gap therebetween. A central shaft extends outwardly from the rotor, and a bearing element is disposed insupporting relationship with the central shaft for providing bearing support of the rotor within the stator. A lubricant is disposed in the gap for providing additional or auxiliary lubricant supportof the rotor within the stator. In an alternative arrangement, the central shaft is operably connected with a drive assembly, which is operably connected with a wheel hub assembly. In this arrangement, the bearing element is disposed in supporting relationship with the wheel hub assembly. In either arrangement, the wheel end electric motor includes both lubricant support as well as bearing supportfor optimizing performance of the electric motor in shock load environments.
一种电动机,该电动机包括定子和可移动地设置在定子内以在其间限定间隙的转子。中心轴从转子向外延伸,并且轴承元件以与中心轴支撑的关系设置,用于提供转子在定子内的轴承支撑。润滑剂设置在间隙中,用于提供转子在定子内的附加或辅助润滑剂支撑。在替代布置中,中心轴与驱动组件可操作地连接,该驱动组件与轮毂组件可操作地连接。在该布置中,轴承元件以与轮毂组件支撑的关系设置。在任一布置中,轮端电动机包括用于优化电动机在冲击载荷环境中的性能的润滑剂支撑以及轴承支撑。
