The invention discloses an electric drive axle assembly which comprises a motor, an axle housing, a differential mechanism and a hub unit assembly. The two axle housings are installed on the two sides of the motor respectively, and the two hub unit assemblies are installed on the two axle housings respectively. The differential mechanism is installed in one axle housing, and the motor transmits power to sun wheel shafts of the two hub unit assemblies through the differential mechanism. The hub unit assembly comprises a speed reducer shell, a planet carrier, a sun wheel shaft and a planet wheel; the speed reducer shell is fixed to the end, away from the motor, of the axle housing, the planet carrier is rotationally installed in the speed reducer shell, and one end of the planet carrier extends out of the speed reducer shell to serve as a hub. The planet wheel is rotationally mounted on the planet carrier, and the planet wheel is meshed with a protruding annular inner tooth part in the speed reducer shell; the two ends of the sun wheel shaft are rotationally connected with the axle housing and the planet carrier correspondingly. In this way, the structure of the drive axle is more compact, arrangement of the whole vehicle is more convenient, and the drive axle can obtain larger loads.

    本发明公开了一种电驱动桥总成,包括电机、桥壳、差速器以及轮毂单元总成;两个桥壳分别安装在电机两侧,两个轮毂单元总成分别安装在两个桥壳上;差速器安装一个桥壳内,电机通过差速器将动力分别传递至两个轮毂单元总成的太阳轮轴;轮毂单元总成包括减速器壳体、行星架、太阳轮轴和行星轮;减速器壳体固定在桥壳上远离电机的一端,行星架转动安装在减速器壳体内,行星架的一端从减速器壳体内伸出作为轮毂使用;行星轮转动安装在行星架上,行星轮与减速器壳体内部凸起的环状内齿部相啮合;太阳轮轴的两端分别与桥壳和行星架转动连接。这样使得驱动桥的结构更加紧凑,更加便于整车布置,并且使驱动桥可以获得更大的负载。
