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，当大多数汽车处于3AT和4MT级别时，更多的齿轮确实意味着更好的加速和功率输出平稳性，以及更低的油耗和更高的速度。但是，现在，在汽车里的食物和衣服，今天的装备，不再是评价一辆汽车的标准。

　　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.

　　误解1:更多的块意味着更快的速度

　　Misunderstanding 1: more blocks means faster speed

　　相同引擎的汽车，当他们有更多的变速箱时，速度会加快，但“齿轮越多，速度越快”并不构成因果逻辑。汽车的加速性能是由齿轮箱能承受的起始速度,齿轮变速箱的速度,和前几个齿轮的传动比,这是密切相关的校准汽车公司,和齿轮的数量不是太多。

　　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.

　　误区二:块更有代表性，移动更流畅

　　Myth 2: blocks are more representative and move more smoothly

　　档位平滑受诸多因素影响，但档位的多少并不起决定性作用。更多的齿轮只能说明齿数比差小，发动机转速差小，而不能直接解释平稳换档。自动变速箱也是一样，液力变矩器代替离合器的存在决定了“旋律”的上下起伏，而液力变矩器的标定则由汽车厂家决定，如液体粘度、齿轮正时和速度补偿等，直接影响着变速箱的平稳性。

　　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.

　　误差三:块体更能代表较低的油耗

　　Error 3: block is more representative of lower fuel consumption

　　多档变速箱的设计是为了实现更好的燃油经济性，大多数六档自动变速箱肯定比三档变速箱消耗更少的燃油。多档齿轮可以带来更大的齿数比，齿数比也可以更小，使发动机高速巡航速度更低，油耗更低，但实际情况并非。你不必每分钟减少燃油喷射的数量来确定发动机的燃油经济性,你必须看到发动机的瞬时增加负载,这是更致命的——N + 1不仅损害发动机和变速箱,但是这真的不是省油!

　　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!
