The integrated electric drive axle two-gear speed reducer transmission device comprises a driving motor and a main shaft, the outer side wall of the driving motor is connected with a first-stage planet row sun gear through a spline, and the outer side wall of the first-stage planet row sun gear is symmetrically connected with three first-stage planet row planet gears in a meshed mode. The three first-stage planet row planet gears are driven by the first-stage planet row sun gear, the main shaft is driven to rotate by the first-stage planet row planet carrier through spline connection, the output driving gear is driven by the gear shifting spline housing, and therefore the effect of two-stage speed reduction of the half shaft is achieved, and meanwhile the speed of the half shaft is increased by changing the position of the gear shifting spline housing. The gear shifting spline housing is connected with the spline of the planet carrier of the second-stage planet row while being not separated from the output driving gear, three-stage speed reduction can be carried out on the half shaft, the coaxial design of the driving motor and the main shaft is adopted, a planet gear mechanism is selected, the structure is compact, the overall weight is reduced, the size is reduced, and the endurance mileage of the vehicle is increased.

    本发明公开了一种集成电驱桥两档减速器传动装置,包括驱动电机和主轴,所述驱动电机的外侧壁通过花键连接有第一级行星排太阳轮,所述第一级行星排太阳轮的外侧壁对称啮合连接有三个第一级行星排行星轮。本发明通过第一级行星排太阳轮带动三个第一级行星排行星轮,通过第一级行星排行星架通过花键连接带动主轴转动,通过换挡花键套带动输出主动齿轮,进而起到了对半轴二级减速的效果,同时,通过改变换挡花键套的位置,使换挡花键套不与输出主动齿轮脱离的同时与第二级行星排行星架花键连接,可以对半轴进行三级减速,通过采用驱动电机和主轴同轴式设计,选用行星齿轮机构,结构紧促,降低了整体的重量,减小了体积,增加了车辆续航里程。
