1、 I 摘摘 要要 汽车转向器是汽车的重要组成部分，也是决定汽车主动安全性的关键 总成，它的质量严重影响汽车的操纵稳定性。随着汽车工业的发展，汽车 转向器也在不断的得到改进，虽然电子转向器已开始应用，但机械式转向 器仍然广泛地被世界各国汽车及汽车零部件生产厂商所采用。而在机械式 转向器中，循环球齿条-齿扇式转向器由于其自身的特点被广泛应用于各级 各类汽车上。 本文选择GX1608A型循环球齿条-齿扇式转向器作为研究课题， 其主要内容有：汽车转向器的组成分类；转向器总成方案分析及其数据确 定和转向器的设计过程。 这种转向器的优点是，操纵轻便，磨损小，寿命长。缺点是结构复杂， 成本高，转向灵敏度不如

2、齿轮齿条式。因此逐渐被齿轮齿条式取代。但随 着动力转向的应用，循环球式转向器近年来又得到广泛使用。 关键词关键词；转向器 操纵稳定性 循环球齿条-齿扇式转向器 II Abstract Gear cars an important component of the initiative is decided automobile safety of the key assembly, It seriously affected the quality of the vehicle handling and stability. Along with the development of the

3、auto industry, automobile steering gear is continuously improved, although the electronic steering gear has begun to use But mechanical steering gear is still widely been world motor vehicles and parts manufacturers adopted. And the mechanical steering gear, Rack cycle ball-type steering gear tooth

4、fans as its own characteristics has been widely used in various types vehicles. The graduation design options GX1608A cycle gear ball-type steering gear rack as a research topic, Its main contents are : automotive steering gear components classification; assembly was to program analysis and data to identify and steering gear design process. The advantage of such steering gear, and manipulating light, wear and tear, long life. The disadvantage is that the structure is complicated and costly,
