摘 要
在汽車行駛中，轉向運動是最基本的運動。我們通過方向盤來操縱和控制汽車的行駛方向，從而實現(xiàn)自己的行駛意圖。在現(xiàn)代汽車上，轉向系統(tǒng)是必不可少的最基本的系統(tǒng)之一，它也是決定汽車主動安全性的關鍵總成，如何設計汽車的轉向特性，使汽車具有良好的操縱性能，始終是各汽車廠家和科研機構的重要課題。特別是在車輛高速化、駕駛人員非職業(yè)化、車流密集化的今天，針對更多不同的駕駛人群，汽車的操縱性設計顯得尤為重要。
本文主要介紹汽車轉向系的組成和作用，并且采用相關數(shù)據(jù)進行設計機械式轉向系統(tǒng)的設計，考慮各種機械轉向器的利弊進行分析和計算設計相應的轉向操縱和轉向傳動機構。
首先，根據(jù)給定車型確定主要參數(shù)并確定轉向器形式及類型；其次，進行轉向系的總體設計；再次，進行轉向器的結構設計并根據(jù)使用要求進行校核；最后，針對設計的轉向器確定轉向操縱機構及轉向傳動機構的選擇及設計。
關鍵詞:轉向系統(tǒng)；轉向器；齒輪齒條；轉向梯形；轉向節(jié)；轉向節(jié)臂
ABSTRACT
Changing to motion in running in the automobile, is the most fundamental motion. We pass the intention and controlling automobile direction running , running realizing self thereby to come to control the steering wheel. On Hyundai Motor, changing to system is one of essential the most fundamental system , it is also the assembly deciding active security of automobile key, characteristic property how to design the automobile vergence, the automobile has a messenger fine control a function , be every automobile manufacturer and important institution for scientific research problem all the time. The personnel who high speed-rization , drives especially in the vehicle is not occupation-rization, vehicle stream concentrated -rization today, nature designs that specifically for still more different driving crowd , the automobile controlling appearing especially important.
The automobile the main body of a book is introduced mainly changes to the composition and effect being , the advantages and disadvantages adopt the relevance data to carry out the implement designing that machinery style changes to systematic design , thinking that various machinery gets lost carries out analysis and calculates the organization designing that corresponding vergence controls and changes to drive and.
First, according to a given model and determine the main parameters determining the form and type of steering gear; Secondly, the overall design of the steering system; again, the structural design of the steering gear and in accordance with the requirements of verification; Finally, the design of the steering Determine the steering control mechanism and the steering linkage of the selection and design.
Key words:Steering system；Steering gear；Rack and pinion；Steering trapezoidal；Steering knuckle；Steering knuckle arm
