The invention relates to a large-turning-angle double-trailing-arm suspension integrated steer-by-wire system which comprises a steering motor, a speed reducer, a wheel steering rotation pair and wheels which are sequentially in transmission connection from top to bottom, and the wheel steering rotation pair is connected with a vehicle body through an upper trailing arm and a lower trailing arm. Compared with the prior art, the steering motor has the advantages of meeting the high-speed rotation condition of the steering motor under the condition of a large reduction ratio, being high in space utilization rate and small in vertical space occupation, effectively limiting axial movement of the steering knuckle relative to the shaft sleeve, achieving +/-90-degree wheel steering, being light in weight and the like.
本发明涉及一种大转角的双纵臂悬架一体化线控转向系统,该系统包括由上至下依次传动连接的转向电机、减速器、车轮转向转动副以及车轮,所述的车轮转向转动副分别通过上纵臂与下纵臂与车身连接。与现有技术相比,本发明具有满足转向电机在大减速比条件下的高速转动情况、空间利用率高、垂向空间占用小、有效限制转向节相对于轴套的轴向移动、实现±90°车轮转向以及轻量化等优点。
