摘要
汽车转向系统经历了纯机械转向系统、机械液压动力转向系统到电控液压动力转向
系统,直到更为节能、操纵性更好的电子控制式电动助力转向系统(eps)等几个阶段,电动助力转向采用电动机直接提供动力,助力大小由电控单元控制,具有助力大小可调,路感良好,环保,耗能低,维修方便等优点。
本论文在对电动转向系统的基础上,研究了捷达轿车转向系统的结构,捷达汽车转向系统各个部分的作用、组成、主要构造、工作原理、及可能出现的故障,同时提出了对出现的故障进行维修的可行方案;采用了理论与实际相结合的方法,对每个问题都有良好的认识,对所学内容进行了良好的总结归纳,以此进一步熟悉掌握汽车转向系统的各方面知识,深化巩固所学知识,做到理论与实际相结合,在理论学习的前提下,用实际更好的理解所学内容。

Abstract
Automotive steering system has experienced a pure mechanical steering system, mechanical hydraulic power steering system to the electronic control hydraulic power steering system, until more energy saving, better electronic control electric power steering system (EPS) and other stages, electric power steering motor directly to provide power, power size by the electronic control unit control, with power adjustable, good road, environmental protection, low energy consumption, maintenance and other advantages.
In this paper on the basis of the electric power steering system on JETTA steering system structure,Jetta car to various parts of the system, composition, main structure, working principle, and the fault, and puts forward the feasible scheme for the maintenance of the fault; using the theory and method of combining the, to each of the questions have good understanding, to study the content of the good summary induction, in order to further familiar with the automotive steering system all aspects of knowledge, consolidating and deepening the knowledge, achieve the combination of theory and practice, the premise in the study of the theory, practice to better understanding.
