The invention relates to a pure electric steering system of a heavy commercial vehicle. The pure electric steering system comprises a steering wheel, a large-torque pure electric redundant steering gear and a steering pull rod. The steering wheel is connected with the steering pull rod through the large-torque pure electric redundant steering gear. The large-torque pure electric redundant steering gear comprises an angle transmission input shaft mechanism, a sensor module, a mechanical transmission mechanism, a speed reducing mechanism module and a motor power control module. The motor power control module decelerates and increases the torque output by a motor through the speed reducing mechanism module arranged at the bottom of the large-torque pure electric redundant steering gear, then is connected with a mechanical transmission mechanism and outputs the torque from a steering sector gear arm shaft assembly, and the sensor module is connected with the system controller and collects rotation angle and torque signals. And a current vehicle speed signal of the vehicle is read through a CAN, output torque is controlled through a motor power control module, and power-assisted output of the vehicle under different steering working conditions is achieved.

    本发明涉及一种重型商用车纯电动转向系统,包括方向盘、大扭矩纯电动冗余转向器及转向拉杆;方向盘通过大扭矩纯电动冗余转向器与转向拉杆连接:大扭矩纯电动冗余转向器包括角传动输入轴机构、传感器模块、机械传动机构、减速机构模块及电机动力控制模块,电机动力控制模块通过布置于大扭矩纯电动冗余转向器底部的减速机构模块将电机输出力矩减速增扭后,与机械传动机构衔接,并从转向扇齿臂轴总成输出,传感器模块与系统控制器连接,采集转角及扭矩信号,并通过CAN读取车辆当前车速信号,通过电机动力控制模块控制输出力矩,实现车辆不同转向工况的助力输出。
