The invention is directed to a wheel assembly (1) for an electric vehicle comprising a wheel hub motor with a stator (100) that has a stator housing (120) comprising a stator housing widened section (121) having an in general cylindrical shape and extending in an axial direction (x). The stator housing (120) is at an in axial direction (x) proximal end (122) merging into a stator axle (110) arranged coaxially to and extending away from the stator housing (120). The stator axle (110) has a smaller diameter (Ds) than the stator housing widened section (121). The wheel assembly (1) further a rotor (200) comprising a rotor housing (220) that is arranged coaxially to and rotatable around the stator (100). The rotor housing (220) has a rotor housing widened section (221) encompassing at least aportion of the stator housing widened section (121) at a certain distance. The rotor housing widened section (221) at an in axial direction (x) proximal end (122) merges into a hollow-cylindrical rotor axle (210) having a smaller diameter than the rotor housing widened section (221) According to the invention the rotor (200) is supported with respect to the stator axle (110) by at least one bearing (900, 910).

    本发明涉及一种用于电动车辆的车轮组件(1),包括车辆轮毂马达,车辆轮毂马达具有定子(100),定子具有定子壳体(120),定子壳体包括定子壳体加宽部段(121),定子壳体加宽部段具有总体上柱形的形状并且在轴向方向(x)上延伸。定子壳体(120)在沿轴向方向(x)的近侧端部(122)处与定子轴(110)结合,定子轴布置成与定子壳体(120)同轴并且背离定子壳体(120)延伸。定子轴(110)具有比定子壳体加宽部段(121)的直径小的直径(Ds)。车轮组件(1)进一步包括转子(200),转子包括转子壳体(220),转子壳体布置成与定子(100)同轴并且可以围绕定子(100)旋转。转子壳体(220)具有转子壳体加宽部段(221),转子壳体加宽部段在一定距离处包围定子壳体加宽部段(121)的至少一部分。转子壳体加宽部段(221)在沿轴向方向(x)的近侧端部(122)处与中空柱形转子轴(210)结合,中空柱形转子轴具有比转子壳体加宽部段(221)的直径小的直径。根据本发明,转子(200)相对于定子轴(110)被至少一个轴承(900、910)支撑。
