A continuously variable transmission,or CVT,is a type of automatic transmission that provides more useable power,better fuel economy and a smoother driving experience than a traditional automatic.[.p]
Driving a car with a CVT
The controls for a CVT are the same as an automatic:Two pedals (no clutch) and a P-R-N-D-L-style shift pattern.But while an automatic transmission has a set number of gear ratios (a.k.a.speeds),usually 4,5 or 6,the CVT can constantly change the relationship of engine speed to car speed.When driving a car with a CVT,you never hear or feel the transmission shift -- it simply raises and lowers the engine speed as needed,calling up higher engine speeds (or RPMs) for better acceleration and lower RPMs for better fuel economy while cruising.
Many people find the CVT disconcerting at first because of the way cars with CVTs sound.When you step on the accelerator,the engine races as it would with a slipping clutch or a failing automatic transmission.This is normal -- the CVT is adjusting the engine speed to provide optimal power for acceleration.
How the CVT works
Traditional transmissions use a gearset that provides a given number of ratios (or speeds).The transmission (or the driver) shifts gears to provide the most appropriate ratio for a given situation:Lowest gears for starting out,middle gears for acceleration and passing,and higher gears for fuel-efficient cruising.
Though there are several types of CVTs,most cars use a pair of variable-diameter pulleys,each shaped like a pair of opposing cones,with a metal belt or chain running between them.One pulley is connected to the engine (input shaft),the other to the drive wheels (output shaft).The halves of each pulley are moveable; as the pulley halves come closer together the belt is forced to ride higher on the pulley,effectively making the pulley's diameter larger.Changing the diameter of the pulleys varies the transmission's ratio (the number of times the output shaft revolves for each revolution of the engine),in the same way that a 10-speed bike routes the chain over larger or smaller gears to change the ratio.Making the input pulley smaller and the output pulley larger gives a low ratio (a large number of engine revolutions producing a small number of output revolutions) for better low-speed acceleration.As the car accelerates,the pulleys vary their diameter to lower the engine speed as car speed rises.This is the same thing a conventional automatic or manual transmission does,but while a conventional transmission changes the ratio in stages by shifting gears,the CVT continuously varies the ratio -- hence its name

一个不断无级变速器,或无级变速器,是一种自动变速器,提供更多的可用功率和更好的燃油经济性和更顺畅的驾驶体验比传统的自动.[ .p ]
开车与无级变速器
这些控制的无级变速器是一样的自动：两个踏板（无离合器）和PRNDL风格的转变模式.但是,虽然自动变速器拥有一套渔具数量的比率（又名速度） ,通常4日,5日或6日,无级变速器可以不断变化的关系,发动机转速到汽车的速度.当开车与无级变速器,你从来没有听到或感觉到的传输转变-它只是提高和降低发动机转速的需要,要求更高了发动机转速（或客运）为更好地加速和更低的客运更好的燃油经济性,而巡航.
许多人觉得这是一个令人不安的无级变速首先是因为汽车的方式与CVTs声音.当你一步加速器,发动机的比赛,因为它将与滑动离合器或未能自动变速器.这是正常的-的无级变速器是调整发动机转速,以提供最佳的功率加速.
如何无级变速器工程
传统的传输使用gearset ,提供一定数量的比率（或速度） .传输（或司机）转变齿轮,提供最适当的比例为某一特定的情况：最低齿轮开始了,中间齿轮的加速和传球,和更高的齿轮燃油效率的巡航.
尽管有几种类型的CVTs ,大多数车使用双可变直径滑轮,每一个形状像一对反对锥,用金属链带或它们之间运行.一个滑轮连接到引擎（输入轴） ,其他的驱动车轮（输出轴） .在每个半场滑轮是动产;作为滑轮半来密切结合起来带是被迫乘坐较高的滑轮,有效地使皮带轮的直径增大.改变直径的滑轮不同的传输的比例（次数输出轴旋转的每个革命的引擎） ,以同样的方式,一个10速自行车路线链的大或小齿轮改变比例.制作滑轮的投入小,产出大让滚筒低比率（大量的引擎革命生产少量的输出革命）为更好地低速加速.随着汽车加快,他们滑车不同直径,降低发动机转速的车速上升.这是同样的事情一个常规自动或手动变速箱没有,但同时改变传统的传动比,分阶段的转向齿轮,不断的无级变速器不同的比例-因此它的名字
