摘 要
汽車若在冰雪路面或無(wú)路的情況下行駛時(shí)，就要求增加驅(qū)動(dòng)車輪的數(shù)目，以充分利用汽車的重量來(lái)增加車輪與道路間的附著力。分動(dòng)器的主要功用是將發(fā)動(dòng)機(jī)輸出的動(dòng)力分配到各驅(qū)動(dòng)橋，并且進(jìn)一步增大扭矩；其另一個(gè)功用是兼起副變速器的作用。分動(dòng)器也是一個(gè)齒輪傳動(dòng)系統(tǒng)，它單獨(dú)固定在車架上，其輸入軸與分動(dòng)器的輸出軸用萬(wàn)向傳動(dòng)裝置連接，分動(dòng)器的輸出軸有若干根，分別經(jīng)萬(wàn)向傳動(dòng)裝置與各驅(qū)動(dòng)橋相連。
本設(shè)計(jì)根據(jù)匹配車型的使用條件和車輛參數(shù)選擇分動(dòng)器的結(jié)構(gòu)形式，并按照分動(dòng)器總成的設(shè)計(jì)步驟和要求，對(duì)其主要零部件，如齒輪、軸進(jìn)行了相關(guān)的設(shè)計(jì)工作和校核工作。并根據(jù)汽車設(shè)計(jì)、汽車?yán)碚摗C(jī)械設(shè)計(jì)、機(jī)械設(shè)計(jì)課程等參考資料提供的相關(guān)知識(shí)，對(duì)計(jì)算出的分動(dòng)器具體參數(shù)進(jìn)行檢驗(yàn)，并論證設(shè)計(jì)的合理性。最終，用AutoCAD軟件完成分動(dòng)器二維裝配圖和零件圖的繪制。

ABSTRACT
If car drive in snow and ice road or no way under the condition of the road, it’s to ask for an increase in the number of driver wheels，To take full advantage of the weight of the car to increase the wheels and the adhesion between road，The main function is to thansfer engine output power distribution to the driving axle, and further increase torque, the other a function is and the deputy variable speed.Thansfer is also a gear transmission system, it alone in frames, the fixed input shaft and thansfer output shaft with universal transmission devices connected, thansfer output shaft several root, the universal respectively with each drive transmission device connected.
This design according to the conditions of use and matching model vehicle parameter selection of structure form, and thansfer according to the design procedures of the assembly thansfer and requirement, for its main parts, such as gear, the shaft related design work and check work. And according to the car design, car theory, mechanical design, mechanical design courses provide reference information for the relevant knowledge, calculated from the concrete parameters for inspection, thansfer and demonstrates the rationality of the design. Finally, with AutoCAD software thansfer 2 d assembly drawings and component drawing.
Key words:Thansfer; points; center distance;Gear；Axis；Meshing sets
