The invention provides a coaxial three-stage speed reduction electric drive axle adopting a cylindrical gear differential mechanism. The coaxial three-stage speed reduction electric drive axle comprises a motor, a three-stage speed reducer, the differential mechanism, a half shaft and wheels which are in power connection in sequence, wherein an output shaft of the motor and the half shaft are coaxially arranged, and the differential mechanism is constructed to be a cylindrical gear differential mechanism. The coaxial three-stage speed reduction electric drive axle further comprises an integrated shell which is arranged on a frame and used for accommodating the three-stage speed reducer and the differential mechanism, and a motor shell which is arranged on the frame and used for accommodating the motor, wherein the motor shell and the integrated shell are independently arranged. According to the invention, the characteristic of high-rotating-speed output of the differential mechanism ismet, and uniform meshing and stable power output of gears at the high rotating speed are guaranteed; and the motor and the half shaft are coaxially installed, and the structure is more compact.

    本发明提供一种采用圆柱齿轮差速器的同轴式三级减速电驱动桥,包括依次动力连接的电机、三级减速器、差速器、半轴和车轮;电机的输出轴和半轴同轴设置,差速器构造为圆柱齿轮差速器,还包括设置在车架上容纳三级减速器和差速器的集成壳体,设置在车架上容纳电机的电机壳,电机壳和集成壳体相互独立设置。本发明满足了差速器高转速输出的特性,保证了高转速下齿轮均匀的啮合和平稳的动力输出;电机和半轴采用同轴安装,结构更加紧凑。
