摘　　要：为解决牵引车转弯时的视野盲区问题,提出牵引车后视镜随轮转向系统设计方法。通过设置后视镜传动系统的参数,选择控制芯片、单片机的类型以及舵机系统,编写WAVE汇编程序进行随轮转向控制,实现后视镜视野方向与牵引车转弯角度的相对应。模拟试验结果表明:牵引车转弯时,随轮转向系统能够扩宽驾驶员后视镜视野4.8%~26.7%,提高了牵引车的行驶安全。A new tractor rear-view mirror drive system is presented in this paper which responds to wheel steering and increases the field of vision.The system achieved the rear-view mirror view angle changing with the angle of the tractor turning by designing new parameters of the rear view mirror drive system,new type of the control chip,SCM and the steering gear system,and writing a WAVE assembler.The experimental simulation results show that the system enlarges the vision of the rearview mirror on a corner-turning tractor by 4.8% to 26.7% and the driving safety of the tractor has thus been improved.
