The invention belongs to the technical field of electric vehicles, and particularly relates to a wheel-side motor for an electric vehicle, a hub assembly and the electric vehicle. The wheel edge motor at least comprises a fixed main shaft, a power part and a speed reduction part, the power part and the speed reduction part are sequentially arranged along the fixed main shaft, the power part comprises a rotor, the rotor comprises a rotor bearing assembly and a rotor sleeve shaft installed on the fixed main shaft through the rotor bearing assembly, and the speed reduction part comprises a speed reduction shell forming a speed reduction cavity. The rotor bearing assembly comprises a rotor bearing and a rotor oil seal, a first oil duct is formed among the fixed main shaft, the rotor oil seal and the rotor sleeve shaft, and the first oil duct is communicated with the speed reduction cavity. The first oil duct communicated with the speed reduction cavity is formed among the fixed main shaft, the rotor bearing assembly and the rotor sleeve shaft, and oil in the first oil duct can be transmitted, fused and exchanged with oil in the speed reduction cavity; therefore, more effective and quicker heat dissipation can be realized through more components in the speed reduction cavity, the speed reduction shell and the like.
本发明属于电动车技术领域,具体涉及一种电动车用轮边电机、轮毂总成以及电动车。轮边电机至少包括固定主轴,以及沿固定主轴依次设置的动力部分和减速部分,其中,动力部分包含转子,转子含有转子轴承组件以及通过该转子轴承组件安装在固定主轴上的转子套轴,减速部分包含形成减速腔体的减速外壳,转子轴承组件包括转子轴承和转子油封,固定主轴、转子油封与转子套轴之间形成第一油道,该第一油道与减速腔体相连通。本发明固定主轴、转子轴承组件以及转子套轴之间形成与减速腔体相连通的第一油道,第一油道内的油液能够与减速腔体内的油液进行传递、融合以及交换,从而通过减速腔体内部的部件以及减速外壳等更多的部件进行更为有效、快速的散热。
