The main function of the universal drive shaft is to transmitting torque and rotation movement between two shafts whose relative position is variation in the working process. At the beginning of this century the transmission shaft and cardin joint play an important role in the development of automobile industry. As the development of automobile industry, the automobile demand that the design and verification of transmission shaft and cardin join stricter in the efficiency, intension, durability and noise performance. This graduation design chooses existing production business enterprise of basis is producing the car type(CA1041) of ten thousand to spread to move to equip the conduct and actions design prototype. Under the conditions of the main technical parameters of the given vehicle, installation location of engine, transmission and other major assembly are determined , the structure of the vehicle is analysised, the transmission shaft layout program is determined. Two shaftthree cardin joints is adapted. After determining the transmission options, the right drive shaft and universal joint assembly, intermediate bearing assembly is designed, so that the assembly can be used in normal situations and the life within no failure. Keywords： Transmission shaft； Cardin joint； Middle supporting； Design ； Verification 目 錄 摘要 I Abstract II 第 1 章 緒論 1 選題的目的和意義 1 國內(nèi)外研究現(xiàn)狀、發(fā)展趨勢 1 研究內(nèi)容及方法 2 傳動(dòng)軸方案的選擇及主要參數(shù)的確定 2 萬向節(jié)類型的選擇 2 十字軸式萬向節(jié)的結(jié)構(gòu)分析 2 萬向節(jié)總成主要參數(shù)的確定與校核 3 中間支承的設(shè)計(jì)與校核 3 第 2 章 傳動(dòng)軸總成的設(shè)計(jì) 5 萬向傳動(dòng) 軸總體概述 5 傳動(dòng)布置型式的選擇 5 傳動(dòng)軸斷面尺寸的確定與強(qiáng)度校核 6 傳動(dòng)軸的運(yùn)動(dòng)分析 6 傳動(dòng)軸斷面尺寸的計(jì)算與校核 9 主傳動(dòng)軸滑動(dòng)花鍵的設(shè)計(jì) 11 中間傳動(dòng)軸花鍵的設(shè)計(jì) 錯(cuò)誤 !未定義書簽。 本章小結(jié) 1
