The invention discloses a wheel edge driving assembly, which relates to the field of automobile parts and comprises a driving shaft and a wheel hub unit, the driving shaft is supported on the wheel hub unit through a support bearing, a driving shaft gear is arranged on the driving shaft and used for driving a driven gear to rotate, a gear shaft is fixedly arranged on the driven gear, and a planetary gear is sleeved on each gear shaft. Each planetary gear is meshed with a sun gear to form a planetary gear train; the sun gear is sleeved on the hub unit and is meshed with an external spline on the outer surface of a flange of the hub unit; a brake disc is coaxially mounted at a flange plate guide end of the hub unit; and the hub unit is mounted on a steering knuckle. According to the invention, a speed reducer is integrated in the assembly, and stable transmission speed reduction is carried out through two-stage speed reduction. Meanwhile, a hub motor bearing unit can bear the maximum torque larger than or equal to 800 Nm, the overall transmission performance of the speed reducer can be effectively enhanced, and the service life of the overall hub motor is prolonged; and the whole structure of the assembly is smaller in size, the structure is more compact, and subsequent assembly with a motor is facilitated.

    本发明公开了一种轮边驱动总成,涉及汽车零部件领域,包括驱动轴和轮毂单元,驱动轴通过支撑轴承支承在轮毂单元上,驱动轴上设有驱动轴齿轮用于带动从动齿轮旋转,从动齿轮上固装有齿轮轴,每一齿轮轴上套装有一只行星齿轮,各行星齿轮与太阳轮啮合组成行星齿轮系;太阳轮套装在轮毂单元上,并与轮毂单元法兰外表面的外花键啮合;轮毂单元的法兰盘引导端上同轴心安装有制动盘;轮毂单元安装在转向节上。本发明将减速机集成于总成内,通过二级减速进行稳定的传动减速;同时,轮毂电机轴承单元可承受最大扭矩≧800Nm,可有效增强减速器整体的传动性能,提高整体轮毂电机的寿命;总成整体结构体积更小,结构更为紧凑,便于后续与电机的装配。
