The invention relates to an electric tractor drive control system which comprises a front axle, a rear axle, a power battery and a drive assembly, wheels are mounted on the front axle and the rear axle respectively, the drive assembly comprises a main controller, a main drive motor, a hydraulic brake, a suspension device and an oil pressure sensor, and the main drive motor is a double-shaft motor.One output shaft of the main driving motor is connected with a second gearbox, the other output shaft of the main driving motor is connected with a hydraulic generating device, the hydraulic generating device is provided with a pressure limiting valve, the front axle is provided with a second electric hydraulic power-assisted steering gear, the suspension device is coupled with a main controller,the oil pressure sensor is coupled with the main controller, and the main controller is provided with a display module. The tractor is driven by the power battery instead of a fuel engine, so that the tractor is relatively stable and environment-friendly; the main driving motor is arranged to simultaneously drive the wheels and the hydraulic generating device to operate, the number of driving sources in the tractor is reduced, and cost is saved.

    本申请涉及一种电动拖拉机驱动控制系统,其包括前桥、后桥,前桥、后桥均安装有车轮,还包括动力电池、驱动总成,驱动总成包括主控制器、主驱动电机、液压制动器、悬挂装置以及油压传感器,主驱动电机为双轴电机,主驱动电机一输出轴连接有变速箱二、另一输出轴连接有液压发生装置,液压发生装置设有限压阀,前桥设有电动液压助力转向器二,悬挂装置与主控制器耦接,油压传感器与主控制器耦接,主控制器具有显示模块。通过以动力电池代替燃油机对拖拉机进行驱动,较为稳定与环保;通过设置以主驱动电机同时驱动车轮以及液压发生装置运行,减少拖拉机中驱动源的数量,节约成本。
