附 錄 From 1894, a French engineer to a car fitted with the worlds first transmission date, transmission has been car a hundred years of development. Important for the automotive transmission component of the commitment to enlarge the engine torque, torsional characteristics of reactive power with the engine, to achieve the desired power transmission, and thus adapt to various road conditions to achieve the main devices driving. The first is the use of manual transmission. Later, for the convenience o f motorists, in the collar between adjacent gear fitted with a synchronizer, the synchronizer rely on, and we do not need to shift to judge the speed. Manual transmission is still present in the automotive industry a wide range of applications, automatic transmission is a trend, but the manual transmission is great fun, embodied persons. The traditional gear transmission with the use of different shift achieved the purpose of twisting, but with the change of gear by foot only hand-off to achieve, and this is the so-called manual transmission. Easily shift to achieve the abolition of clutch pedal and manual the AT (AutomaticTransmission) transmission occurred, it is the main browser using hydraulic Torque traditional mechanical gearbox with the shift function to achieve. In fact, as early as the 1948 Oldsmobile car GM has already emerged on the automatic transmission is now taking shape, but then the automatic transmission is only the addition of hydraulic coupler manual transmission only. AT used because earlier, so the English name is called automatic transmission. However, AT is not the same as in the automatic transmission. As long as we can to achieve the automatic transmission shift automatic transmission can be called, it is necessary to achieve this in fact means a lot: In addition to AT, but also includes other forms of CVT. However, before the overthrow of the name can not, so let us not think so: automatic transmission (AT) including: hydraulic transmission (AT), Electronically Controlled Transmission (ECT), non-polar transmission (CVT). 1908 Ford Model T the first use of a two-speed ratio automatic transmission. Constructed using multiple sets of gear, and gear into the central and peripheral gear, the outside is a runner, with the introduction of the central gear of the torque from the engine is different from camera gear groups so as to be different levels of speed, including Reverse rotation reversing file. Runner-type automatic transmission, there is a drawback, that is, when people start to accelerate there is a feeling of spin the wheels, so drivers will be meng refueling door, but does not immediately increase the speed again. At present, some manufacturers such as Nissan and Fiat, have recourse to some electronic device to try to eliminate this shortcoming, Nissan Primera and the 6-speed transmission Fiat Punto 7-speed gearbox is the result of this effort. Drivers pulled no need to handle, they can easily change the speed. Although the automatic transmission continue to evolve and progress, but there will always be a drawback, that is, the response speed of action and between the pedal there will always be a gap, driving in the impression of a lack of intuition. Appeared in 1969 and the electronic control systems appeared in 1982, which was to improve digital technology. With the engine fuel injection and ignition devices continued to be refined, automatic transmission is also new tricks, such as set up a campaign-style or snow road , such as the manipulation of different ways, some in the instrument panel has a bearing S letter button, you can become extremely rapid acceleration； or snowflake patterns are printed on the button on behalf of the snow moving to avoid slipping in the start. Even worse, a new generation of adaptable style Transmission can also adapt to motorists different habits, the corresponding reaction, so that drivers will become more user-friendly. the intelligent automatic transmission, and spread to the vehicle mass, which is a credit to the French. in 1997 with the Renault Clio Peugeot 206 took the lead in the most advanced computer-controlled technology and is known as fuzzylogie the principle that fuzzy logic. This car can drive based on the temperament, road conditions, vehicle load and the surrounding environment and other factors, in the nine kinds of programs select the most suitable function, the realization of intelligent driving, in order to give full play to the vehicle performance and reduce fuel consumption and ensure safety. now that is, continuously variable transmission CVT (ContinuouslyVariableTransmission) also have been widely used, continuously variable transmission system in the non-use of gears, to provide smooth and no class conversion ratio of the transmission system at the same time light weight, small size, the characteristics of small parts, is recognized as the ideal vehicle transmission. compared to AT, CVT transmission wuji primarily in the drive way there different. The latter is the use of drive belts and the work of the main variable diameter driven wheel to transfer power line in order to achieve the continuous transmission ratio change. However, the traditional CVT technical weaknesses exist, such as the transmission belt easily damaged, can not afford a larger load, etc., makes the transmission has been used in more than a small displacement, low-power vehicles. As technology advances, the energy crisis triggered a global energy conservation and environmental protection awareness, at the conclusion of the first generation of CVT based on the experience, people develop a better performance, greater torque capacity CVT. However, playing in the torque requirements on the CVT model is still unable to take on heavy responsibilities. Continuously Variable Transmission and the common development of electronically controlled automatic transmission also ushered in DSG (dual clutch automatic transmission) the popularity of Volkswagen has now started to apply only to the super sports car before the technology is applied to the ordinary family car has been up. DSG automatic transmission shifting technology enables faster, less power loss, so more fuel-efficient. The development of automatic transmission car seems to have wisdom, and even more good than people think. It changes according to the road outside, after the calculation, instead of smart people to make an accurate decision. 附錄 距 1894 年，一個(gè)法國(guó)工程師給一輛汽車裝上世界上第一個(gè)變速器至今，汽車變速器已經(jīng)經(jīng)過了一百多年的發(fā)展。變速器為汽車重要的組成部分，是承擔(dān)放大發(fā)動(dòng)機(jī)扭矩，配合引擎功扭特性，實(shí)現(xiàn)理想動(dòng)力傳遞，從而適應(yīng)各種路況實(shí)現(xiàn)汽車行駛的主要裝置。 使用最早的是手動(dòng)變速器。后來為 了方便駕駛，在領(lǐng)個(gè)相鄰齒輪間裝上了同步器，依靠同步器的作用，我們換擋就不需要去判斷車速了。目前手動(dòng)變速器依然在汽車界應(yīng)用非常廣泛，自動(dòng)變速器是個(gè)趨勢(shì)，但手動(dòng)變速器確是駕駛樂趣的極大體現(xiàn)者。 傳統(tǒng)的變速器利用不同的齒輪搭配實(shí)現(xiàn)了換擋変扭的目的，而齒輪搭配的變換就只有靠腳踩離合手拉擋桿來實(shí)現(xiàn)，這就是所謂的手動(dòng)變速器。為實(shí)現(xiàn)輕松換擋，取消離合腳踏和手動(dòng)掛擋的 AT(AutomaticTransmission)變速器出現(xiàn)了，它主要利用液力變扭器配合傳統(tǒng)機(jī)械齒輪箱實(shí)現(xiàn)換擋功能。其實(shí)早在 1948 年的通用的奧茲莫比爾汽車上 就已經(jīng)出現(xiàn)了如今自動(dòng)變速器的雛形，不過那時(shí)的自動(dòng)變速器僅僅是加了液力耦合器的手動(dòng)變速器而已。 因?yàn)?AT 使用得較早，所以英文定名就叫“自動(dòng)變速器”。然而， AT 并不等同于自動(dòng)變速器。只要能實(shí)現(xiàn)自動(dòng)換擋變速的便可叫自動(dòng)變速器，要達(dá)到此目的其實(shí)途徑很多：除 AT 外，還包括了無級(jí)變速器等其它形式。但以前的命名也無法推翻，所以我們姑且這樣認(rèn)為：自動(dòng)變速器（ AT）包括：液力變速（ AT） ,電控變速（ ECT） ,無極變速（ CVT） . 1908 年，福特 T 型車最早采用一種兩個(gè)速比的自動(dòng)變速器。其構(gòu)造是采用多組齒輪，并且分成中央齒輪和 周邊齒輪，最外邊則是一個(gè)轉(zhuǎn)輪，隨著中央齒輪從發(fā)動(dòng)機(jī)引入的扭矩不同，齒輪組相機(jī)行事，從而得到高低不一的轉(zhuǎn)速，包括倒車檔的反向旋轉(zhuǎn)。轉(zhuǎn)輪式自動(dòng)變速器存在一個(gè)缺點(diǎn)，即起步加速時(shí)令人有一種車輪打滑的感覺，于是駕車人會(huì)猛加油門，但車速又并不隨即增高。目前已有一些廠家，如日產(chǎn)和菲亞特，求助于電子裝置來設(shè)法消除這一缺點(diǎn)，日產(chǎn) Primera 的 6 速變速器與菲亞特 Punto 的 7 速變速器便是這番努力的結(jié)果。駕車者根本無需扳動(dòng)手柄，便可以輕松自如地改變車速。 雖然自動(dòng)變速器不斷地演變進(jìn)步，但始終有缺點(diǎn)，即車速的反應(yīng)與踏板的動(dòng)作之間 總有一定的差距，駕駛中缺乏直覺的印象。 1969 年出現(xiàn)的電子控制系統(tǒng)及 1982 年出現(xiàn)的數(shù)字技術(shù)對(duì)此作了改進(jìn)。 隨著發(fā)動(dòng)機(jī)燃油噴射與點(diǎn)火裝置的不斷完善，自動(dòng)變速器也有新的花樣，如設(shè)置了“運(yùn)動(dòng)式或“雪地行駛”等不同的操控方式，有的在儀表盤上
