The invention provides a differential type double-planet-row hub reduction mine truck electric drive axle. The differential type double-planet-row hub reduction mine truck electric drive axle comprises a drive motor, an intermediate shaft, a first planet row and a second planet row. A low-speed large-torque single motor can be adopted as a power source to directly input power to the hub reduction gear through the half shaft, or a plurality of high-speed motors can be adopted as the power source to input the power to the hub reduction gear through the half shaft after the power is converged through the reduction gear, the application range is wide, and the range of the provided power is large; the differential type double-planet-row hub reduction mechanism is large in speed ratio range, the speed ratio range can reach 20-200, and the requirement of a transmission box with the large input rotating speed range is completely met; according to the differential type double-planet-row hub reduction mechanism, the large speed ratio is met, meanwhile, the transmission path is short, the number of gear meshing times is small, and the transmission efficiency is higher; by adopting the wheel-side electric drive axle with the structure, the structure can be simplified, the number of parts can be reduced, the assembly difficulty can be reduced, the reliability can be improved, and the cost can be saved.

    本发明提供一种差动式双行星排轮边减速矿卡电驱动桥,包括驱动电机,中间轴,第一行星排,第二行星排;既可以采用低速大扭矩单电机做为动力源,通过半轴直接输入到轮边减速器,也可以采用多个高速电机做为动力源,动力经减速齿轮汇合后,通过半轴输入到轮边减速器,适用范围广,可提供动力范围大;差动式双行星排轮边减速机构速比范围大,可以达到20‑200,完全满足大输入转速范围传动箱的需求;差动式双行星排轮边减速机构,在满足大速比的同时,传动路径短,齿轮啮合次数少,传动效率更高;采用了该结构的轮边电驱动桥,可以实现结构减化,减少零部件数量,降低装配难度,提高可靠性并节省成本。
