摘　　要：针对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工况,论文在等转向前束角模型的基础上提出了非等转向前束的方法用于确定汽车的转向中心,对转向不汇交时的转向中心分布区间进行了证明,推导了非等转向前束数学模型,并结合某车的转向机构实际参数值,分析了其转向过程中内、外转向轮转向前束角分布规律,得出相关结论。According to the situation that if the steering does not meet the Ackermann theorem while low-speed steering ignoring the tire cornering,based on equal-steering-toe-in model,a method called not-equal-steering-toe-in used to determine the turning center is presented,and then the distribute interval of turning center is proved.It also deduces not-equal-steering-toe-in mathematical model.On this basis,combined with the actual parameters value of a car,it analyzes the distribution law of steering-toe-in for its inside and outside steering wheel,and finally draws relevant conclusions.
