The invention relates to a dual-power-output electric drive axle which comprises a drive motor, an air cylinder and an axle. Air enters through the front end of the air cylinder to push a sliding meshing sleeve on an output shaft spline seat to move from the end A to the end B, the sliding meshing sleeve is combined with a first-stage driven gear spline, and the output shaft spline seat is connected with an auxiliary power output flange through a spline; At the moment, a first-stage driven gear, a sliding meshing sleeve, an output shaft spline seat and an output flange are connected for transmission, and auxiliary power output is achieved; Air enters the rear end of the air cylinder to push the sliding meshing sleeve on the output shaft spline seat to move from the end B to the end A, the sliding meshing sleeve is disengaged from the first-stage driven gear spline, and auxiliary power output is interrupted. According to the drive axle, when the whole pure electric truck is arranged, a motor does not need to be independently adopted for providing auxiliary power or a power takeoff does not need to be designed and installed, the arrangement space is saved, the weight of the whole truck is reduced, meanwhile, the integration level is improved, the transmission efficiency is improved, and more endurance mileage can be obtained.
本发明涉及一种双动力输出电驱动桥,该驱动桥,包括驱动电机、气缸和车桥。气缸前端进气,推动输出轴花键座上的滑动啮合套从A端移动至B端,滑动啮合套与第一级从动齿轮花键结合,输出轴花键座与辅助动力输出法兰通过花键连接;此时第一级从动齿轮、滑动啮合套、输出轴花键座与输出法兰连接传动,实现辅助动力输出;气缸后端进气,推动输出轴花键座上的滑动啮合套从B端移动至A端,滑动啮合套与第一级从动齿轮花键脱开,辅助动力输出中断。本发明的驱动桥可使纯电动卡车在整车布置时,不用单独采用电机提供辅助动力或设计安装取力器,节省布置空间,减轻整车重量,同时提高了集成度,提高传动效率,得以获得更多的续航里程。
