自動變速箱的誕生源于人們想把駕駛者的左腳徹底解放出來并降低駕駛車輛的難度，因此自動變速箱在變速箱領域享有至高無上的地位，是全球車企爭先研發(fā)的重點。隨著時代的發(fā)展，自動變速箱技術逐漸成熟起來，解決了平順和油耗的問題，越來越受到消費者喜愛。
The birth of automatic transmission is derived from people who want to completely liberate the driver's left foot and reduce the difficulty of driving. Therefore, the automatic transmission has the highest position in the gearbox, which is the focus of the global car enterprise. With the development of the times, the technology of automatic transmission has gradually matured, and the problem of smoothness and fuel consumption has been solved, which is more and more popular among consumers.
不過，傳統(tǒng)自動變速箱對液力變矩器的依賴過大，這決定了傳統(tǒng)自動變速器的擋位數(shù)不能過多。液力變矩器是實現(xiàn)自動換擋的關鍵部件，幾乎AT和CVT都有采用。主動和被動葉輪依靠中間油液實現(xiàn)動力傳輸，減少發(fā)動機扭矩瞬間提高對變速箱造成的沖擊，幫助車輛實現(xiàn)平穩(wěn)起步。它的優(yōu)點是安全穩(wěn)定沒有散熱問題，缺點同樣也很明顯，相比純機械連接的方式，由于加入了油液，傳動效率比較低，導致費油。因此，近50年來汽車工程師研發(fā)重點都集中在了提高效率上，對擋位數(shù)并不關注。
However, the traditional automatic transmission is too dependent on the torque converter, which determines that the number of gears in the traditional automatic transmission can not be excessive. Hydraulic torque converter is the key component to achieve automatic shift. Almost AT and CVT are used. The active and passive impeller rely on Intermediate oil to realize the power transmission, reduce the moment of engine torque to increase the impact on the gearbox, and help the vehicle to achieve a smooth start. Its advantages are the safety and stability of the problem of no heat dissipation, the shortcomings are also very obvious, compared to the pure mechanical connection, because of the addition of oil, low transmission efficiency, resulting in oil. Therefore, in the past 50 years, the focus of R & D of Automotive Engineers has been focused on improving efficiency and ignoring the number of gears.
與此同時，在傳統(tǒng)自動變速箱上增加擋位數(shù)十分困難。擋位的增多會讓傳統(tǒng)自動變速箱變得越來越大、越來越重，以如今的技術和工藝水平造出體積小、重量輕、成本可控的變速箱幾乎是不可能的，因此傳統(tǒng)自動變速箱的發(fā)展一直受到限制。
At the same time, it is very difficult to increase the number of gears on traditional automatic transmission. The increase of the gear will make the traditional automatic transmission become bigger and heavier. It is almost impossible to create small, light and cost controlled transmission with the technical and technological level today, so the development of the traditional automatic transmission has been limited.

為了擺脫效率問題，很多工程師獨辟蹊徑，開始研發(fā)與傳統(tǒng)自動變速箱完全不同工作原理的自動變速箱。近年，ZF和愛信開始通過改變齒輪組結(jié)構(gòu)設計和擋位增加，以解決傳統(tǒng)自動變速箱的效率問題，并率先在Jeep自由光和路虎極光上搭載了9速自動變速箱。此外，通用和福特在2013年宣布聯(lián)合研發(fā)9速和10速自動變速箱，大眾集團宣布10速雙離合變速箱開發(fā)工作已經(jīng)開始，現(xiàn)代汽車成功研發(fā)的10速變速箱，將于2014年投入到量產(chǎn)中。未來，自動變速箱的擋位會越來越多。
To get rid of the problem of efficiency, many engineers have developed a new type of automatic transmission, which is completely different from the traditional automatic transmission. In recent years, ZF and asin began to increase the design and gear of the gear group to solve the problem of the efficiency of the traditional automatic transmission and take the lead in carrying 9 speed automatic transmission on the Jeep free light and the Land Rover aurora. In addition, in 2013, general and Ford announced the joint development of 9 and 10 speed automatic transmission, the Volkswagen Group announced that the 10 speed double clutch transmission has begun, and the 10 speed gearbox developed by modern cars will be put into production in 2014. In the future, there will be more and more gears for automatic transmission.
越來越先進的技術讓變速箱增加擋位不再是難題。較近幾年變速箱擋位越來越多，但遠沒達到安全穩(wěn)定可靠的水平。一些車型著急上馬擋位數(shù)更多的變速箱，其實是想通過擋位數(shù)塑造車輛的先進性，博個技術噱頭。目前僅有幾個小眾品牌車型搭載了多擋位自動變速箱。
With more and more advanced technology, increasing gear shift is no longer a problem. In recent years, gearboxes are more and more blocked, but they are far from safe, stable and reliable. Some models are more anxious to get more gear boxes. Actually, they want to shape the advanced nature of the vehicles through the number of gears, and make a technical gimmick. At present, only a few minority brand models are equipped with multi shift automatic transmission.
多擋位變速箱會隨著規(guī)模效應的影響擴大，逐步降低生產(chǎn)成本、維修成本，但更大的問題還在于更復雜的結(jié)構(gòu)。從汽車機械工程的角度來看，變速箱擁有更多擋數(shù)就會讓每一個齒輪同時搭配更多傳動零部件，這就意味著制造更復雜，結(jié)構(gòu)更精密，體積越大。這樣的變速箱必然會對消費者駕駛習慣提出更高的要求，因為它需要十分挑剔的照顧。
The multi shift gearbox will expand with the influence of scale effect and gradually reduce production cost and maintenance cost, but the bigger problem is more complicated structure. From the point of view of the mechanical engineering of the car, the more gear with the gearbox will allow each gear to match more transmission parts at the same time, which means that the manufacturing is more complex, more precise, and the larger the volume. Such a gearbox is bound to put a higher demand on consumer driving habits, because it needs very picky care.
