HLJIT4H-10二軸四擋變速器設(shè)計（含CAD圖紙和說明書）,HLJIT4H,10,二軸四擋,變速器,設(shè)計,CAD,圖紙,說明書 摘　　要 從汽車誕生時起，汽車變速器在汽車傳動系中扮演著至關(guān)重要的角色?，F(xiàn)代汽車上廣泛采用內(nèi)燃機(jī)作為動力源，其轉(zhuǎn)矩和轉(zhuǎn)速變化范圍較小，而復(fù)雜的使用條件則要求汽車的動力性和燃油經(jīng)濟(jì)性能在相當(dāng)大的范圍內(nèi)變化。為解決這一矛盾，在傳動系統(tǒng)中設(shè)置了變速器。本文以五羊本田新鋒影摩托車的一些整車參數(shù)和發(fā)動機(jī)參數(shù)為依據(jù)，進(jìn)行變速器的設(shè)計。設(shè)計的主要內(nèi)容包括變速器傳動機(jī)構(gòu)布置方案的確定，變速器主要參數(shù)如擋數(shù)、傳動比范圍、中心距、各擋傳動比、外形尺寸、齒輪參數(shù)、各擋齒輪齒數(shù)的選擇，齒輪、軸、軸承的設(shè)計校核，同步器、操縱機(jī)構(gòu)及箱體的設(shè)計。在設(shè)計的過程中，本文根據(jù)轎車變速器的設(shè)計要求和車輛動力傳動系統(tǒng)自身的特點，參考多篇文獻(xiàn)資料，以及國內(nèi)外變速器設(shè)計圖冊，從經(jīng)濟(jì)性和實用性方面著手進(jìn)行分析,設(shè)計出一種兩軸式變速器。 關(guān)鍵詞：變速器；齒輪；軸；箱體；設(shè)計 ABSTRACT Since automobile was born, the transmission has played a critical role in the drive train. A modern car widely uses engines as the power source. The range of torque and speed are small, but complex using conditions require the automobile’s dynamic and fuel economical efficiency can change in a very large range. To solve this contradiction, transmission is set up in the drive train. The transmission is designed based on engine parameters and vehicle parameters of Wu Yang Ben Tian Xin Feng Ying automobile in this text. The main design contents include the layout program of transmission drive-mechanism, the selection of main transmission parameters such as shifts, the range of gear ratio, center-spacing, each gear ratio, size, gear parameters and the mumble of each gear, the design and verification of gears, shafts and bearings, the design of synchronizer, manipulation-framework and gearbox. Bases on the design requirement and the characteristic of power transmission system, consulting a great deal of literatures and transmission design drafts from both home and overseas, at economical efficiency and practicability angle, a small kind of two-shafted transmission is designed.
