摘 要
隨著產(chǎn)業(yè)布局、產(chǎn)品結(jié)構(gòu)的調(diào)整，就業(yè)結(jié)構(gòu)也將發(fā)生變化。企業(yè)對(duì)較高層次的第一線應(yīng)用型人才的需求將明顯增加，培養(yǎng)相當(dāng)數(shù)量的具有高等文化水平的職業(yè)人才，成為迫切要求。因此熟悉汽車(chē)轉(zhuǎn)向系統(tǒng)，熟練掌握現(xiàn)代化汽車(chē)轉(zhuǎn)向系統(tǒng)的設(shè)計(jì)、操作和維護(hù)的應(yīng)用型高級(jí)技術(shù)人才成為社會(huì)較緊缺、企業(yè)最需要的人才。
隨著汽車(chē)工業(yè)的迅速發(fā)展，轉(zhuǎn)向裝置的結(jié)構(gòu)也有很大變化?，F(xiàn)代汽車(chē)轉(zhuǎn)向裝置的設(shè)計(jì)趨勢(shì)主要向適應(yīng)汽車(chē)高速行駛的需要、充分考慮安全性、輕便性、低成本、低油耗、大批量專(zhuān)業(yè)化生產(chǎn)發(fā)展。
本文闡述了汽車(chē)轉(zhuǎn)向系統(tǒng)各個(gè)部分的作用、組成、主要構(gòu)造、工作原理、及可能出現(xiàn)的故障，同時(shí)提出了對(duì)出現(xiàn)的故障進(jìn)行維修的可行方案；采用了理論與實(shí)際相結(jié)合的方法，對(duì)每個(gè)問(wèn)題都有良好的認(rèn)識(shí)，對(duì)所學(xué)內(nèi)容進(jìn)行了良好的總結(jié)歸納，以此進(jìn)一步熟悉掌握汽車(chē)轉(zhuǎn)向系統(tǒng)的各方面知識(shí)，深化鞏固所學(xué)知識(shí)，做到理論與實(shí)際相結(jié)合，在理論學(xué)習(xí)的前提下，用實(shí)際更好的理解所學(xué)內(nèi)容。

Abstract
With the adjustment of industry layout and product structure, the structure of employment will change. The demand for higher level front-line talents will increase obviously, and it will be urgent to train a large number of professional talents with higher educational level. Therefore, familiar with the automobile steering system, skilled grasp of modern automobile steering system design, operation and maintenance of application of advanced technical personnel, become more scarce society, the most needed talents.
With the rapid development of the automobile industry, the structure of the steering device has also changed greatly. The design trend of modern automobile steering device is mainly to meet the needs of high speed vehicle, fully consider the safety, portability, low cost, low fuel consumption and mass production.
This paper expounds the fault of the various parts of the system function, composition, main structure, working principle, and possible steering, and puts forward the feasible scheme for the maintenance of the fault; using the method of combining theory and practice, have a good understanding of each problem, a good summary to study the content, in order to further familiar with the automotive steering system of all aspects of knowledge, deepen consolidate knowledge, achieve the combination of theory and practice, in the premise of theory study, with practice to better understand the content.
Keywords：energy saving car steering braking
