Appendix China in the first half of 2008 about 93 million trucks accumulative total sales of cars, vans 61 million vehicles, year-on-year growth of 20.2%, visible light car in commercial car production has a large proportion. And driving axle is very important in the vehicle driving axle is the important car auto bearing assembly, auto frame and integral by suspension of body vertical force, to lead the longitudinal forces, transverse force and torque, and impact load； Driving axle also delivers the t r a n s m i s s i o n , t h e m a x i m u m t o r q u e r e a c t i o n i s u n d e r . Automobile driving axle structure and design parameters in addition to the reliability of the automobile and durability have important influence on the outside, also for the automobile driving performance such as power, economy, smooth, t h r o u g h s e x , m o b i l i t y Automobile driving axle design involves the mechanical parts and components is widely to these varieties, spare parts, components and assemblies manufacturing also almost want to design to all modern machinery manufacturing process, design a simple structure, reliable operation and low cost, can greatly reduce the drive axle of the total cost of the vehicle production, promote economic development, and car to drive through the car studying and designing practice, can better learning and mastery of the modern car design and mechanical design of the comprehensive knowledge and skills, and the overall thinking and operation skill check, drawing, is the very important link, so ontology of a structure design of fine vans axles has certain Automobile driving axle is one of the main parts car, its basic function is to enlarge the shaft or by the torque transmission spread, then torque distribution to drive wheels, and make about driving wheel has about vehicle movement required differential function； Axles in the end of powertrain system, choose proper Lord slowdown, ensure cars than with sufficient ground clearance is achieved, gear and other transmission job need to ensure smooth are the parameters, and even bear effect on the pavement drive axle and frame or carrying body vertical force, the lead between transverse and longitudinal force and torque force. Driving axle quality, performance will have a direct impact on the vehicles safety, economy, comfort and reliability. After the car driving axle design can make the students comprehensive by using their This thesis research aims to overall matching car by driving axle Lord finish design of gear reducer, differential component such as type of design and calculation, and complete checking and comprehensive design single main reducer, then the batch Through the design of the vehicle driving axle should also master the understanding, including each component interaction between the body and the electrical system, the influence and cooperate to drive axle of the process and therefore more familiar with vehicle mastery. That in the future the production and living effectly use. 附 錄 我國(guó) 2008年上半年貨車?yán)塾?jì)銷售約 93萬輛，其中輕型貨車 61萬輛，同比增長(zhǎng)20.2%，可見輕型汽車在商用汽車生產(chǎn)中占有很 大的比重。而且驅(qū)動(dòng)橋在整車中十分重要， 汽車驅(qū)動(dòng)橋是汽車的重要總成，承載著汽車車架及承載式車身經(jīng)懸架給予的鉛垂力、縱向力、橫向力及其力矩，以及沖擊載荷；驅(qū)動(dòng)橋還傳遞著傳動(dòng)系中的最大轉(zhuǎn)矩，橋殼還承受著反作用力矩。汽車驅(qū)動(dòng)橋結(jié)構(gòu)型式和設(shè)計(jì)參數(shù)除對(duì)汽車的可靠性與耐久性有重要影響外，也對(duì)汽車的行駛性能如動(dòng)力性、經(jīng)濟(jì)性、平順性、通過性、機(jī)動(dòng)性和操動(dòng)穩(wěn)定性等有直接影響。 汽車驅(qū)動(dòng)橋設(shè)計(jì)涉及的機(jī)械零部件及元件的品種極為廣泛，對(duì)這些零部件、元件及總成的制造也幾乎要設(shè)計(jì)到所有的現(xiàn)代機(jī)械制造工藝， 設(shè)計(jì)出結(jié)構(gòu)簡(jiǎn)單、工作可靠 、造價(jià)低廉的驅(qū)動(dòng)橋，能大大降低整車生產(chǎn)的總成本，推動(dòng)汽車經(jīng)濟(jì)的發(fā)展，并且 通過對(duì)汽車驅(qū)動(dòng)橋的學(xué)習(xí)和設(shè)計(jì)實(shí)踐，可以更好的學(xué)習(xí)并掌握現(xiàn)代汽車設(shè)計(jì)與機(jī)械設(shè)計(jì)的全面知識(shí)和技能，以及整體的思維和運(yùn)算校核等本領(lǐng)，繪圖也是其中非常重要的環(huán)節(jié)， 所以本題設(shè)計(jì)一款結(jié)構(gòu)優(yōu)良的 輕型貨車驅(qū)動(dòng)橋 具有一定的實(shí)際意義 汽車驅(qū)動(dòng)橋是汽車的主要部件之一，其基本功用是增大由傳動(dòng)軸或變速器傳來的轉(zhuǎn)矩，再將轉(zhuǎn)矩分配給左右驅(qū)動(dòng)車輪，并使左右驅(qū)動(dòng)車輪具有汽車行駛運(yùn)動(dòng)所要求的差速功能；驅(qū)動(dòng)橋處于動(dòng)力傳動(dòng)系的末端，選擇適當(dāng)?shù)闹鳒p速比，保證汽車具有足夠 的離地間隙，齒輪及其他傳動(dòng)件工作平穩(wěn)都是需要保證的參量，同時(shí)驅(qū)動(dòng)橋還要承受作用于路面和車架或承載車身之間的鉛垂力、縱向力、橫向力及其力矩。驅(qū)動(dòng)橋質(zhì)量、性能的好壞直接影響整車的安全性、經(jīng)濟(jì)性、舒適性、可靠性。設(shè)計(jì)汽車后驅(qū)動(dòng)橋能使學(xué)生綜合運(yùn)用所學(xué)專業(yè)知識(shí)，熟練
