In order to solve the problems that when an electric vehicle driving hub in the prior art goes downhill or is pushed by manpower, large resistance can be caused by interaction of a motor rotor and a stator, and a motor cannot always run in an optimal state, the invention provides a variable-speed electric vehicle driving hub which comprises a hub body and a hub body, the device comprises an axle, a stator, a rotor, a hub, a tire and a spring clutch, the axle is fixedly connected with a front fork or a rear fork of the electric vehicle; the stator is fixed on the wheel shaft; the rotor sleeves the outer side of the stator; the hub is sleeved on the outer side of the rotor; the outer circle of the hub outer ring is sleeved with the tire. The spring clutch is arranged on the right side of the hub, and power transmission and separation between the right rotor disc and the right hub disc are achieved through the spring clutch. The invention has the beneficial technical effects that the wheels are separated from the rotor of the motor, so that the motor is free from resistance during free sliding, the motor is always kept in an optimal state to run through speed regulation, and the motor can also run in a reverse gear.

    为解决现有技术电动车驱动轮毂存在着遇到下坡或人力推动时,电机转子与定子的相互作用会造成较大的阻力,以及电机不能始终保持在最佳状态运行等问题,本发明提出一种可变速电动车驱动轮毂,包括,轮轴、定子、转子、轮毂、轮胎和弹簧离合器;所述轮轴与电动车的前叉或后叉固定连接;所述定子固定在轮轴上;所述转子套装在定子外侧;所述轮毂套装在转子外侧;所述轮胎套装在轮毂外环的外圆;所述弹簧离合器设置在轮毂的右侧,右转子圆盘通过弹簧离合器实现其与右轮毂圆盘之间的动力传输和分离。本发明的有益技术效果是车轮与电机转子分离,可以在自由滑行时不受阻力,并通过调速使电机始终保持在最佳状态运行,还可倒档运行。
