The invention discloses a hub motor end cover structure of a pure electric vehicle. The structure comprises an inner ring unit, an outer ring unit and a plurality of reinforcing rib modules, wherein the inner ring unit and the outer ring unit are concentrically arranged and are connected with each other through reinforcing ribs; each reinforcing rib module comprises a first reinforcing rib and a second reinforcing rib, the first reinforcing ribs and the second reinforcing ribs are distributed in a bilateral symmetry mode along the extension line of the diameter of an inner ring, one end of each reinforcing rib is connected with an inner edge of the outer ring unit, the other end of each reinforcing rib is connected with an outer edge of the inner ring unit, and the included angle between extension lines of the first reinforcing ribs and the second reinforcing ribs is 45 degrees. Compared with the prior art, the weight of the end cover is reduced to the maximum extent, the unsprung massof a hub motor in the whole vehicle is finally reduced, the reliability of the motor under various working conditions is guaranteed, the actual mass of the motor is reduced, the irregularity and comfort of the whole vehicle and the actual use space in the vehicle are improved, and the actual transmission efficiency of the vehicle is improved.
一种纯电动汽车轮毂电机端盖结构,包括内圈单元、外圈单元和多个加强筋模块,所述的内圈单元和外圈单元同心设置并且通过加强筋互相连接,每个加强筋模块包括第一加强筋和第二加强筋,所述的第一加强筋和第二加强筋沿着内圈直径的延长线左右对称分布,均一端连接外圈单元内沿,另一端连接内圈单元外沿,第一加强筋和第二加强筋延长线的夹角为45度。与现有技术相比,本发明最大化地降低端盖的重量,最终减小轮毂电机在整车中的簧下质量,保证了电机在多种工况下的可靠性并减轻了电机的实际质量,提升了整车的不平顺度、舒适度和车内实际使用空间,增大了汽车实际传动效率。
