The invention relates to the technical field of electric vehicles, and particularly relates to an integrated three-stage speed reduction electric drive axle. The integrated three-stage speed reductionelectric drive axle comprises an integrated shell, wherein the integrated shell is internally provided with a motor, a three-stage parallel speed reduction gear set and a differential mechanism whichare in transmission connection in sequence, and the integrated shell is of an integrally-formed structure. The integrated three-stage speed reduction electric drive axle further comprises an axle housing, a half shaft and wheels, wherein the two sides of the integrated shell are connected with the axle housing, the half shaft is arranged in the axle housing, one end of the half shaft is connectedwith the output end of the differential mechanism, and the other end of the half shaft is connected with the wheels. The system is high in integration degree, compact in structure and small in occupied space, a transmission shaft is not needed, a battery pack can be arranged in the middle of a vehicle girder, the adaptability to the complete vehicle is good, and the assembling process is simple.

    本发明涉及电动汽车技术领域,特别是一种集成式三级减速电驱动桥,包括集成壳体,集成壳体内设置有依次传动连接的电机、三级平行减速齿轮组和差速器,集成壳体为一体成型结构;还包括桥壳、半轴和车轮,集成壳的两侧连接桥壳,半轴设置在桥壳内部,半轴的一端和差速器的输出端连接且另一端连接车轮。系统集成度高,结构紧凑,占用空间小,不需要传动轴,电池包可以布置在车辆大梁中间,与整车的适配性好,装配工艺简单。
