摘 要
在汽車行駛中，轉(zhuǎn)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(zhuǎn)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(guān)鍵總成，如何設計汽車的轉(zhuǎn)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(gòu)的重要課題。特別是在車輛高速化、駕駛?cè)藛T非職業(yè)化、車流密集化的今天，針對更多不同的駕駛?cè)巳?，汽車的操縱性設計顯得尤為重要。
本文主要介紹汽車轉(zhuǎn)向系的組成和作用，并且采用相關(guān)數(shù)據(jù)進行設計機械式轉(zhuǎn)向系統(tǒng)的設計，考慮各種機械轉(zhuǎn)向器的利弊進行分析和計算設計相應的轉(zhuǎn)向操縱和轉(zhuǎn)向傳動機構(gòu)。
首先，根據(jù)給定車型確定主要參數(shù)并確定轉(zhuǎn)向器形式及類型；其次，進行轉(zhuǎn)向系的總體設計；再次，進行轉(zhuǎn)向器的結(jié)構(gòu)設計并根據(jù)使用要求進行校核；最后，針對設計的轉(zhuǎn)向器確定轉(zhuǎn)向操縱機構(gòu)及轉(zhuǎn)向傳動機構(gòu)的選擇及設計。
關(guān)鍵詞:轉(zhuǎn)向系統(tǒng)；轉(zhuǎn)向器；齒輪齒條；轉(zhuǎn)向梯形；轉(zhuǎn)向節(jié)；轉(zhuǎn)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
