摘 要
汽車傳動(dòng)系是汽車的核心組成部分。其任務(wù)是調(diào)節(jié)變換發(fā)動(dòng)機(jī)的性能，將動(dòng)力有效而經(jīng)濟(jì)地傳至驅(qū)動(dòng)車輪，以滿足汽車的使用要求。變速器是完成傳動(dòng)系任務(wù)的重要部件，也是決定整車性能的主要部件之一。變速器的設(shè)計(jì)水平對(duì)汽車的動(dòng)力性、燃料經(jīng)濟(jì)性、換擋操縱的可靠性與輕便性、傳動(dòng)平穩(wěn)性與效率等都有直接的影響。隨著汽車工業(yè)的發(fā)展,轎車變速器的設(shè)計(jì)趨勢(shì)為增大變速器傳遞功率與重量之比,并要求變速器具有較小的尺寸和良好性能。雙中間軸變速器具有廣泛的適用性，良好的整車匹配性。廣泛匹配載重車、自卸車、牽引車及各種專用車輛和特種車輛，為重型汽車的升級(jí)換代提供較好優(yōu)化配置。
本文主要是對(duì)9檔雙中間軸變速器進(jìn)行傳動(dòng)方案的設(shè)計(jì),對(duì)主要零件軸、齒輪進(jìn)行結(jié)構(gòu)設(shè)計(jì)，對(duì)其他零件進(jìn)行結(jié)構(gòu)和選型設(shè)計(jì)。進(jìn)行齒輪的設(shè)計(jì):包括材料選擇、參數(shù)計(jì)算、強(qiáng)度計(jì)算及校核；軸的設(shè)計(jì)：包括結(jié)構(gòu)設(shè)計(jì)并作出軸的計(jì)算簡(jiǎn)圖、強(qiáng)度校核；軸承的選用及其他零件的結(jié)構(gòu)設(shè)計(jì)。

ABSTRACT
Drivetrain is the core components of automobile. Its task is transforming and regulateing the performance of engine. Transmission can effectively and economically conveyed the power to the wheel which can meet the requirement of vehicles. Transmission is the important part of drivetrain components to complete the tasks. as well as one of the main factor to decide the whole performance of vehicle. The standards of Transmission designing can directly impact the vehicle dynamics, fuel economy, the reliability and portability of shifting, the smoothness and efficiency of Transmiting. Along with the development of the automobile industry, the trend of car transmission designing is to increase its transmission power and decrese its weight ,and hope have smaller size and excellent performance.
This paper mainly describes the design of nine block manual transmission, the transmission principle of work elaborated, Transmission of the gear shaft and do a detailed design, and the intensity of a school. For some standard parts for the selection. Transmission Trans mission program design. A brief description of the trans mission of all components of the material choice.
Keywords: Nine block manual transmission;Transmission；
