SUV leisure cities around the world demand shows a growth trend. SUV in the comfort, safety and fuel economy growing concern by the people. Therefore, SUV design takes into account cross-country capability, but also pay more attention to comfort, safety and fuel consumption。 Suspension and steering system design of the automobile design, a very important component. The reference design similar models on the basis of the motor vehicles suspension and steering system design methods, Actually oriented functions, a reasonable lower manufacturing costs. First select a steering system and suspension structure, according to the SUV used in specific circumstances, with the design requirements, determining perspective shift﹑turning radius to form and the structure of devices to all parts of the structure and strength. Suspension structure﹑main parameters﹑oriented institutions﹑absorber and spring﹑horizontal stabilizer design. So that suspension and steering system meet the performance SUV。 The steering system so that the suspension and re-balance between power and fuel economy on the basis of rational choice of the structure, make a reasonable size, the layout is easy to install. But can be used for other models, have a broad prospect。 KEY WORDS : steering system, suspension, gear rack, hydraulic 目 錄 第一章 前言............ ............................1 第二章 轉(zhuǎn)向系設計.....................................2 §2.1 轉(zhuǎn)向系概述.....................................2 §2.1.1 轉(zhuǎn)向系的設計要求............................2 §2.1.2 轉(zhuǎn)向系概論..................................3 §2.2 轉(zhuǎn)向系設計.....................................7 §2.2.1 轉(zhuǎn)向性能與阿可曼幾何學......................7 §2.2.2 轉(zhuǎn)向系方案分析及確定.......................9 §2.2.3 轉(zhuǎn)向系主要性能參數(shù)的確定...................12 §2.2.4 轉(zhuǎn)向系的載荷驗算...........................15 §2.2.5 轉(zhuǎn)向傳動機構及優(yōu)化設計.....................16 §2.2.6 轉(zhuǎn)向橫拉桿設計與校核.......................20 §2.2.7 轉(zhuǎn)向節(jié)的設計...............................22 §2.2.8 轉(zhuǎn)向器及液壓助力裝置的設計.. . .............23 第三章 懸架設計.....................................30 §3.1懸架概述.....................................30 §3.1.1 懸架概論..................................30 §3.1.2 懸架的設計要求............................30 §3.2懸架的設計....................................31 §3.2.1 懸架的結(jié)構形式與方案分析.................31 §3.2.2 懸架主要參數(shù)的確定......................35 §3.2.3 彈性元件的設計計算....................... 36 §3.2.4 減振器的選擇與設計........................39 §3.2.5 橫向穩(wěn)定桿的設計..........................41 §3.2.6 懸架導向機構的設計........................41 第四章 結(jié)論................................. .........43 致 謝.....................................44 參考文獻.....................................45 III
