The invention provides an integrated hub motor speed reducer which comprises a wheel, a rim is installed on the surface of the wheel, an axle is transversely connected into the wheel, a first-stage planetary gear train assembly is arranged in the wheel, a second-stage planetary gear train assembly is further arranged in the wheel, and the first-stage planetary gear train assembly and the second-stage planetary gear train assembly are arranged in the wheel. A second hub bearing is connected between the first-stage planetary gear train assembly and the second-stage planetary gear train assembly, a first-stage sun gear is connected to the outer wall of the axle, and a first hub bearing is connected between the second-stage planetary gear train assembly and the axle. According to the hub motor reducer, the two levels of planetary reducers are additionally arranged in the single wheel, so that the integrated design of the wheel is achieved, the integration level of the hub motor reducer is higher, meanwhile, through cooperation of the first-level planetary gear train assembly and the second-level planetary gear train assembly, the higher transmission ratio is achieved, and the transmission efficiency is improved. Therefore, the high transmission ratio requirement of the automobile is effectively met.

    本发明提供一种集成式轮毂电机减速器,包括车轮,所述车轮的表面安装有轮辋,所述车轮的内部横向连接有车轴,所述车轮的内部设置有一级行星轮系组件,所述车轮的内部还设置有二级行星轮系组件,所述一级行星轮系组件与二级行星轮系组件之间连接有第二轮毂轴承,所述车轴的外壁连接有一级太阳轮,所述二级行星轮系组件与车轴之间连接有第一轮毂轴承。本发明通过将两个级别的行星减速器加装在单个车轮内,不仅实现了车轮的一体化集成设计,使得轮毂电机减速器的集成度更高的同时,并通过一级行星轮系组件及二级行星轮系组件的配合,实现了更高的传动比,从而有效满足的汽车的高传动比需求。
