The birth of automatic gearbox aims to liberate the left foot of driver, reduce driving difficulty and improve driving comfort. As it turns out, automatic transmissions are indeed more suitable for crowded urban life, so they have become a priority for global automobile companies. With the development of industrial technology, the number of automatic transmission gears is also changing, but is it really better to increase the number of automatic transmission gears?

　　20多年前，當(dāng)大多數(shù)汽車處于3AT和4MT級別時，更多的齒輪確實意味著更好的加速和功率輸出平穩(wěn)性，以及更低的油耗和更高的速度。但是，現(xiàn)在，在汽車?yán)锏氖澄锖鸵路裉斓难b備，不再是評價一輛汽車的標(biāo)準(zhǔn)。

　　More than 20 years ago, when most cars were at 3At and 4mt levels, more gears did mean better acceleration and power output stability, as well as lower fuel consumption and higher speed. But now, the food and clothes in the car, today's equipment, is no longer the standard to evaluate a car.

　　誤解1:更多的塊意味著更快的速度

　　Misunderstanding 1: more blocks means faster speed

　　相同引擎的汽車，當(dāng)他們有更多的變速箱時，速度會加快，但“齒輪越多，速度越快”并不構(gòu)成因果邏輯。汽車的加速性能是由齒輪箱能承受的起始速度,齒輪變速箱的速度,和前幾個齒輪的傳動比,這是密切相關(guān)的校準(zhǔn)汽車公司,和齒輪的數(shù)量不是太多。

　　Cars with the same engine will speed up when they have more gearboxes, but "more gears, faster speed" does not constitute causal logic. The acceleration performance of the car is the starting speed that the gearbox can bear, the speed of the gearbox, and the transmission ratio of the first few gears, which is closely related to the calibration of the car company, and the number of gears is not too much.

　　誤區(qū)二:塊更有代表性，移動更流暢

　　Myth 2: blocks are more representative and move more smoothly

　　檔位平滑受諸多因素影響，但檔位的多少并不起決定性作用。更多的齒輪只能說明齒數(shù)比差小，發(fā)動機轉(zhuǎn)速差小，而不能直接解釋平穩(wěn)換檔。自動變速箱也是一樣，液力變矩器代替離合器的存在決定了“旋律”的上下起伏，而液力變矩器的標(biāo)定則由汽車廠家決定，如液體粘度、齒輪正時和速度補償?shù)?，直接影響著變速箱的平穩(wěn)性。

　　Gear smoothness is affected by many factors, but the number of gears does not play a decisive role. More gears can only explain the small ratio of teeth and the small engine speed difference, but can not directly explain the smooth shift. The same is true for automatic transmission. The existence of hydraulic torque converter instead of clutch determines the ups and downs of "Melody", while the calibration of hydraulic torque converter is determined by automobile manufacturers, such as liquid viscosity, gear timing and speed compensation, which directly affects the stability of transmission.

　　誤差三:塊體更能代表較低的油耗

　　Error 3: block is more representative of lower fuel consumption

　　多檔變速箱的設(shè)計是為了實現(xiàn)更好的燃油經(jīng)濟性，大多數(shù)六檔自動變速箱肯定比三檔變速箱消耗更少的燃油。多檔齒輪可以帶來更大的齒數(shù)比，齒數(shù)比也可以更小，使發(fā)動機高速巡航速度更低，油耗更低，但實際情況并非絕對。你不必每分鐘減少燃油噴射的數(shù)量來確定發(fā)動機的燃油經(jīng)濟性,你必須看到發(fā)動機的瞬時增加負(fù)載,這是更致命的——N + 1不僅損害發(fā)動機和變速箱,但是這真的不是省油!

　　Multi speed transmission is designed to achieve better fuel economy. Most six speed automatic transmission definitely consumes less fuel than three speed transmission. Multi gear gear can bring greater gear ratio, and the maximum gear ratio can also be smaller, making the engine cruise speed lower and fuel consumption lower, but the actual situation is not absolute. You don't have to reduce the amount of fuel injected per minute to determine the fuel economy of the engine. You have to see the instantaneous increase in load of the engine, which is the most fatal - N + 1 not only damages the engine and gearbox, but it's really not fuel saving!
