摘 要
轎車前輪主動轉(zhuǎn)向系統(tǒng)可以確保車輛在任何速度下都能提供理想的轉(zhuǎn)向操控，同時加強了轎車在高速行駛狀態(tài)下的安全性，提高了駕駛員在駕駛汽車時候的靈活性和舒適性,而且相比于傳統(tǒng)的轉(zhuǎn)向器，主動轉(zhuǎn)向系統(tǒng)更加可靠，故障率更低。
本設計以現(xiàn)有主動轉(zhuǎn)向系統(tǒng)裝置為基礎(chǔ)，參考先進的主動轉(zhuǎn)向系統(tǒng)的設計原理和已有汽車的相關(guān)數(shù)據(jù)，重新設計齒輪齒條式轉(zhuǎn)向器及相匹配的主動轉(zhuǎn)向系統(tǒng)機械部分的結(jié)構(gòu)方案，并對相關(guān)的部分進行強度校核。設計的主要內(nèi)容包括：轉(zhuǎn)向系統(tǒng)主要參數(shù)的確定，齒輪齒條轉(zhuǎn)向器的設計，主動轉(zhuǎn)向控制器的設計，其中主動轉(zhuǎn)向是設計中的難點，采用星星齒輪機構(gòu)來實現(xiàn)主動轉(zhuǎn)向的控制，最后運用Auto CAD軟件進行二維圖紙的繪制。

ABSTRACT
Active steering system can ensure vehicles in any speed can provide the ideal steering control, while strengthening the cars in the safety of high-speed condition, improved driver when driving a car the flexibility and comfort, and compared with conventional methods, active steering system more reliable, failure to even lower.
This design is based on the front-wheel existing active steering system, reference information of advanced active steering system and related data of some cars, redesign the theory of steering system with gear and rack and matching active steering system structure scheme of mechanical part. Design of the main content includes: the main steering system of parameters, the design of steering gear rack, active steering the controller design, including active steering is the difficulty in the design, use the stars to implement active steering gear control, finally I use Auto CAD software for the 2D drawings
Key words: redirector; active steering; front wheel; mechanical design; planetary gear
