The invention relates to the technical field of electric forklifts, and discloses a forklift electric driving running system which comprises two driving wheels, a front axle, a speed reducer, a differential mechanism, a running motor and a motor controller, the two driving wheels are installed at the two ends of the front axle respectively, and the front axle is fixed to a forklift frame; each driving wheel is connected with a differential mechanism through a half shaft, the differential mechanism is connected with the output end of a transmission, the input end of the transmission is connected with a motor shaft of a traveling motor, the traveling motor is fixed to a shell of a speed reducer, and the shell is fixed to the middle of a front axle. The driving motor is electrically connected with the motor controller, the motor controller is electrically connected with the whole vehicle controller, and the motor controller is fixed to a forklift frame. The running motor replaces an original engine to serve as power source output, and the rotating speed response speed can be increased; noise and vibration are reduced, no impact exists during gear shifting, and driving is more comfortable; the energy utilization efficiency is improved, and the use requirements of a forklift driving system can be effectively met.

    本发明涉及电动叉车技术领域,公开了一种叉车电驱动行驶系统,包括驱动轮、前桥、减速器、差速器、行驶电机和电机控制器,驱动轮有两个且分别安装在前桥的两端,前桥固定在叉车车架上;每个驱动轮通过半轴与差速器连接,差速器与变速器的输出端连接,变速器的输入端与行驶电机的电机轴连接,行驶电机固定在减速器的壳体上,壳体固定在前桥的中部;行驶电机与电机控制器电性连接,电机控制器与整车控制器电性连接,电机控制器固定在叉车车架上。它通过行驶电机代替原有发动机作为动力源输出,可提高转速响应速度;降低噪声、振动,换挡无冲击,使驾驶更舒适;提高能源利用效率,能有效满足叉车行驶系统使用需求。
