摘 要
汽車變速器是汽車傳動(dòng)系統(tǒng)的主要變速機(jī)構(gòu)，其結(jié)構(gòu)性能對(duì)汽車的動(dòng)力性能、燃油性能、換擋操縱的可靠性與輕便性、傳動(dòng)的平穩(wěn)性與效率都有影響。通過(guò)研究汽車在地起步、爬坡、轉(zhuǎn)彎、加速等行駛工況中變速器的擋位變化，進(jìn)行變速器的各個(gè)部分設(shè)計(jì)，使發(fā)動(dòng)機(jī)在最有利的工況范圍內(nèi)工作。
本設(shè)計(jì)根據(jù)給定的主要技術(shù)指標(biāo)，選擇東風(fēng)EQ1092型汽車作為改進(jìn)的原形，通過(guò)查閱文獻(xiàn)和標(biāo)準(zhǔn)，還原該車變速器的設(shè)計(jì)過(guò)程。
本說(shuō)明書(shū)首先對(duì)變速器傳動(dòng)機(jī)構(gòu)的布置方案進(jìn)行分析，闡述了傳動(dòng)機(jī)構(gòu)的設(shè)計(jì)思路分析了換擋機(jī)構(gòu)的選擇原則，主要介紹了倒擋的布置方案。
然后，計(jì)算了機(jī)械式變速器主要參數(shù)，在不影響穩(wěn)定工作狀態(tài)的情況下，減小變速器的體積和質(zhì)量，同類型結(jié)構(gòu)設(shè)計(jì)采用同一尺寸，旨在改善加工性和經(jīng)濟(jì)性。
最后，選擇同步器的類型，并對(duì)操作機(jī)構(gòu)進(jìn)行設(shè)計(jì)。根據(jù)變速器的具體要求、結(jié)構(gòu)特點(diǎn)等方面綜合考慮,采用簡(jiǎn)單可行的設(shè)計(jì)方法, 有效地提高變速器的換檔能力，使設(shè)計(jì)出來(lái)的變速器能滿足車輛高動(dòng)力性和高經(jīng)濟(jì)性的要求。

ABSTRACT
Auto transmission is the main auto transmission system, the structure performance gear mechanisms for car dynamic performance, fuel performance, reliability and shift anipulated portability, transmission and steadiness and efficiency are having an impact. Through the research to start, climbing a car in turning, accelerate, such as in the running mode,transmission shift transmission changes each part of the design, make the engine at the most favorable conditions range work.
This design according to the given its main technical indices, choose EQ1092 type of dongfeng automobile as improved to archetype, through the literature and standard, restore the vehicle transmission design process.
This manual transmission transmission's first to analyze layout, this paper expounds the design idea of driving mechanism analyzed the choosing principle, shift agencies mainly introduced the reverse gear arranging scheme.
Then, the calculation of the mechanical transmission main parameters, in does not affect the steady working state by reducing the volume and quality, transmission with type structure design USES the same size, aims to improve workability and economy.
Finally, choose the type and synchronizer designed for operators. According to the specific requirements of the gearbox, structural features, and other comprehensive consideration, using simple and feasible design methods, effectively improve the transmission shifting ability, make designed can meet vehicle transmission of high performance and fuel economy of high requirements.
