A harmonic speed reduction middle motor of an electric vehicle is installed on the inner circle of a middle shaft support of an electric vehicle frame, a built-in hub motor is arranged inside the harmonic speed reduction middle motor, a pulley type harmonic generator, a flexible gear ring and a rigid gear ring form an external harmonic speed reducer which is located in the periphery of the built-in hub motor, and deformation of the left end and the right end of the flexible gear ring is symmetrical and consistent, so that the oval outer gear ring and the rigid inner gear ring are meshed in parallel and evenly, the length of the left end and the right end of the flexible gear ring is very short, the axial size of the harmonic speed reduction middle motor of the electric bicycle is reduced,and the speed change fluted disc is installed according to the standard of the bicycle and can be matched with the axial size of a rear wheel. The harmonic speed reduction middle motor of the electricvehicle utilizes an original speed change system of the mountain speed change bicycle to enable the mountain speed change bicycle to have a speed change assisting function. When the motor is used foran electric motorcycle, the harmonic speed reduction middle motor of the electric motorcycle performs multi-stage speed change by using a bicycle speed change system, so that the acceleration property, the dynamic property and the climbing property of the electric motorcycle are enhanced.

    一种电动车谐波减速中置电机,安装在电动车架的中轴支架的内圆,内部设有内置轮毂电机,滑轮式谐波发生器与柔性齿圈和刚性齿圈组成外置谐波减速器,位于内置轮毂电机的外围,柔性齿圈左、右端的变形是对称的、一致的,使椭圆形外齿圈与刚性内齿圈啮合平行、均匀,柔性齿圈左、右端的长度很短,使电动车谐波减速中置电机的轴向尺度缩小,变速齿盘按照自行车的标准进行安装,能与后轮的轴向尺寸匹配;电动车谐波减速中置电机利用山地变速自行车原有的变速系统,使山地变速自行车具有变速助力功能;用于电动摩托车时,电动车谐波减速中置电机利用自行车变速系统的方式进行多级变速,使电动摩托车的加速性、动力性和爬坡性增强。
