According to a commercial vehicle double-motor steer-by-wire system, a power mechanism sequentially passes through three different types of hybrid transmission mechanisms including a two-stage gear speed reduction mechanism, a lead screw transmission mechanism and a rocker arm mechanism, rotary motion is converted into square nut reciprocating linear motion and then converted into swing of a steering rocker arm, and the steering rocker arm rotates wheels through a transverse pull rod; the steer-by-wire device drives the wheels to steer. A mechanical structure of a complex traditional steering system is omitted, the weight is light, maintenance is easy, dual-motor control is adopted, the fault-tolerant capacity of the system is better, and the whole vehicle control stability and yawing response are high; the matching performance of the steer-by-wire system can be improved through program setting, the whole vehicle is more stable, the noise is low, and the transmission efficiency is high.

    一种商用车双电机线控转向系统,动力机构依次通过两级齿轮减速机构、丝杆传动机构、摇臂机构三个不同类型混合传动机构,先将旋转运动转换为方形螺母往复直线运动后又转换为转向摇臂的摆动,转向摇臂通过横拉杆转动车轮,实现该线控转向装置驱动车轮转向。本发明取消了复杂传统转向系统的机械结构,质量轻,易于维护保养,采用双电机控制,系统的容错能力更好,整车操纵稳定性和横摆响应高;可通过程序设置提高线控转向系统的匹配性,整车更为稳定,噪音低,传动效率高。
