汽车转向前束研究Ⅲ

Study on Steering Toe-in of the Vehicles

非等转向前束方法可用于确定汽车低速转向且忽略轮胎的侧偏时,如果转向不满足阿克曼定理(即四轮速度瞬心不汇交)的情况下汽车的转向中心,根据其原理,推导了非等转向前束角的解析算法,得到了非等转向前束角曲线并分析了在有预加前束角的情况下非等转向前束角曲线的变化规律,分析了预加前束具有抵抗干扰恢复直行的能力,转向正前束具有回正作用。

The not-equal-steering-toe-in can be used to determine the turning center during low-speed steering without considering the tire cornering if the steering does not meet the Ackermann theorem. Based on this prin-ciple,the paper deduces analytical method for the situation of not-equal-steering-toe-in. Combined with the ac-tual parameters of a car,the paper analyzes the distribution law of steering-toe-in for its inside and outside steering wheel,and finally draws relevant conclusions. Finally,the paper maintains that toe-in has the ability to resist interference and restore straight drive,and positive steering-toe-in has the ability to return straight.
