The invention relates to an electric drive axle system and a pure electric operation vehicle using the system.The electric drive axle system comprises an axle, the axle comprises an axle main speed reducer, and the electric drive axle system further comprises a drive motor, an operation motor, a drive clutch and an operation clutch, the driving clutch is fixedly mounted on the driving motor, the operation motor is fixedly connected with the driving clutch, and the operation clutch is fixedly connected with the operation motor, so that the driving motor, the operation motor, the driving clutch and the operation clutch are integrally mounted on the axle, and the whole system is compact in layout; and traditional parts such as a transmission shaft and a motor suspension in an existing scheme are omitted, so that the overall cost is effectively reduced. Moreover, the power coupling of the two motors can be realized by utilizing the driving clutch, so that the vehicle can be driven to run together, the power requirement on the motors is reduced, the motors can work in a high-efficiency area, the transmission efficiency is improved, and the power consumption is reduced.

    本发明涉及一种电驱桥系统及使用该系统的纯电动作业车辆,电驱桥系统包括车桥,车桥包括车桥主减速器,电驱桥系统还包括驱动电机、作业电机、驱动离合器及作业离合器,其中,驱动电机固定安装在车桥上,驱动离合器固定安装在所述驱动电机上,作业电机与所述驱动离合器固定连接,作业离合器与作业电机固定连接,从而将驱动电机、作业电机、驱动离合器及作业离合器集成安装在车桥上,使得整个系统布局紧凑,省去了现有方案中的传统的传动轴和电机悬置等零部件,有效降低了整体成本。而且,利用驱动离合器可实现两电机的动力耦合,以能够共同驱使车辆行驶,降低了对电机的功率要求,也使得电机能够在高效区工作,提高传动效率,降低电耗。
