19、把方向盘的旋转运动转变为车辆的直线运动。大部分小型车都接受了齿条齿轮转向器。这套系统须要在传动轴下端尾部安装一个小齿轮。小齿轮与一些嵌在转向联动装置主要交叉部件下方的齿条相啮合。方向盘转动时，这个小齿轮也随之旋转。推动齿条向左或向右运动。这一运动又会通过连杆传递到前轮的转向节臂。Menu Back Next 6.Steering System Your site hereLOGO6Menu Back Next A.Answer the following questions according to the passage.1.What is the function of the steer
