1、本科學(xué)生畢業(yè)論文Eq2102牽引車變速器設(shè)計(jì)系部名稱：汽車工程系專業(yè)班級(jí)：車輛工程B0-6班學(xué)生姓名：指導(dǎo)教師：職稱：講師TheGraduationDesignforBachelor'sDegreeDesignofEq2012forTractorTruckCandidate：Specialty：VehicleEngineeringClass：B07-6Supervisor：InstructorHeilongjiangInstituteofTechnology摘 要變速器是汽車傳動(dòng)系統(tǒng)中比較關(guān)鍵的部件，它的設(shè)計(jì)好壞將直接影響到汽車的實(shí)際使用性能。變速
2、器用來改變發(fā)動(dòng)機(jī)傳到驅(qū)動(dòng)輪上的轉(zhuǎn)矩和轉(zhuǎn)速，目的是在原地起步，爬坡，轉(zhuǎn)彎，加速等各種行駛工況下，使汽車獲得不同的牽引力和速度，同時(shí)使發(fā)動(dòng)機(jī)在最有利工況范圍內(nèi)工作。變速器設(shè)有空擋和倒擋。需要時(shí)變速器還有動(dòng)力輸出功能。因?yàn)樽兯傧湓诘蜋n工作時(shí)作用有較大的力，所以一般變速箱的低檔都布置靠近軸的后支承處，然后按照從低檔到高檔順序布置各檔位齒輪。這樣做既能使軸有足夠大的剛性，又能保證裝配容易。變速箱整體結(jié)構(gòu)剛性與軸和殼體的結(jié)構(gòu)有關(guān)系。一般通過控制軸的長(zhǎng)度即控制檔數(shù)，來保證變速箱有足夠的剛性。本文設(shè)計(jì)研究了兩軸式五擋手動(dòng)變速器，對(duì)變速器的工作原理做了闡述，變速器的各
3、擋齒輪和軸做了詳細(xì)的設(shè)計(jì)計(jì)算，并進(jìn)行了強(qiáng)度校核，對(duì)一些標(biāo)準(zhǔn)件進(jìn)行了選型。變速器的傳動(dòng)方案設(shè)計(jì)并講述了變速器中各部件材料的選擇。全套圖紙，加153893706關(guān)鍵字：擋數(shù)；傳動(dòng)比；齒輪；軸；強(qiáng)度校核IIABSTRACTTransmissionismorecruicalinautomotivedrivelinecomponents,itisdseignedtoditectlyaffectthequalityoftheactualuseofperformanceautomobiles.Transmissiontochangetheenginereached
