Pickup trucks take a large proportion of commercial vehicles production, and the drive axle is one of the most important structure. Drive axle is the one of automobile four important assemblies, Its performance directly influence on the entire automobile, especially for the truck .Because using the big power engine with the big driving torque satisfied the need of high speed, heavy-loaded, high efficiency, high benefit today truck, must exploiting the high driven efficiency single reduction final drive axle is becoming the trucks developing tendency. Design a simple, reliable, low cost of the drive axle, can greatly reduce the total cost of vehicle production, and promote the economic development of automobile and automotive drive axle of the study and design practice, can better learn and to master modern automotive design and mechanical design of a comprehensive knowledge and skills, so the title of the fine structure of the design of a pickup vehicle drive axle has a certain practical significance.In this paper, first of all determine the structure of major components and the main design parameters, the analysis of the various parts of the structure of the bridge drive type, the form of the development process and its advantages and disadvantages of the past, determined on the basis of the design program, using the traditional design method of various parts of the drive axle Main reducer, differential, axle, axle housing was designed to calculate and complete the check. Finally complete the final assembly drawing by using AUTOCAD and mapping the main components. Keywords: Pickup truck; Drive axle; Single reduction final drive; Differential; Axle; Drive Axle housing 目 錄摘要IAbstractII第1章 緒論11.1 選題的背景目的及意義11.2 國(guó)內(nèi)外驅(qū)動(dòng)橋研究狀況11.3 設(shè)計(jì)主要內(nèi)容和預(yù)期結(jié)果3第2章 驅(qū)動(dòng)橋的總體方案確定42.1驅(qū)動(dòng)橋的種類(lèi)結(jié)構(gòu)和設(shè)計(jì)要求42.1.1汽車(chē)車(chē)橋的種類(lèi)42.1.2驅(qū)動(dòng)橋的種類(lèi)42.1.3驅(qū)動(dòng)橋結(jié)構(gòu)組成42.1.4 驅(qū)動(dòng)橋設(shè)計(jì)要求52.2 設(shè)計(jì)車(chē)型主要參數(shù)52.3主減速器結(jié)構(gòu)方案的確定62.3.1 主減速比的計(jì)算62.3.2 主減速器的齒輪類(lèi)型62.3.3 主減速器的減速形式82.3.4 主減速器主從動(dòng)錐齒輪的支承形式及安裝方法92.4 差速器結(jié)構(gòu)方案的確定102.5半軸的形式確定112.6 橋殼形式的確定122.7本章小結(jié)13第3章 主減速器設(shè)計(jì)143.1概述143.2主減速器齒輪參數(shù)的選擇與強(qiáng)度計(jì)算143.2.1 主減速器計(jì)算載荷的確定143.2.2 主減速器齒輪參數(shù)的選擇153.2.3 主減速器齒輪強(qiáng)度計(jì)算183.2.4 主減速器軸承計(jì)算243.3主減速器齒輪材料及熱處理303.4主減速器的潤(rùn)滑303.5 本章小結(jié)31第4章 差速器設(shè)計(jì)324.1概述324.2對(duì)稱(chēng)式圓錐行星齒輪差速器原理324.3 對(duì)稱(chēng)式圓錐行星齒輪差速器的結(jié)構(gòu)334.4對(duì)稱(chēng)圓錐行星錐齒輪差速器的設(shè)計(jì)344.4.1 差速器齒輪的基本參數(shù)選擇344.4.2 差速器齒輪的幾何尺寸計(jì)算364.4.3 差速器齒輪的強(qiáng)度計(jì)算37 4.4.4 差速器齒輪的材料39 4.5 本章小結(jié)39第5章 半軸設(shè)計(jì)405.1概述405.2半軸的設(shè)計(jì)與計(jì)算405.2.1全浮式半軸的計(jì)算載荷的確定405.2.2半軸桿部直徑的初選425.2.3 全浮式半軸強(qiáng)度計(jì)算425.2.4 全浮式半軸花鍵強(qiáng)度計(jì)算425.2.5 半軸材料與熱處理445.3 本章小結(jié)44第6章 驅(qū)動(dòng)橋橋殼的設(shè)計(jì)456.1概述456.2橋殼的受力分析及強(qiáng)度計(jì)算456.2.1 橋殼的靜彎曲應(yīng)力計(jì)算456.2.2 在不平路面沖擊載荷作用下橋殼的強(qiáng)度476.2.3 汽車(chē)以最大牽引力行駛時(shí)的橋殼的強(qiáng)度計(jì)算476.2.4 汽車(chē)緊急制動(dòng)時(shí)的橋殼強(qiáng)度計(jì)算496.2.5 汽車(chē)受最大側(cè)向力時(shí)橋殼強(qiáng)度計(jì)算506.3 本章小結(jié)54結(jié)論55參考文獻(xiàn)56致謝57附錄A58附錄B64
