2023年8月29日 · What is a CVT? A Continuously Variable Transmission (CVT) is a type of automatic transmission that can seamlessly change through a continuous range of effective gear ratios. It does not have fixed gears like a traditional automatic or manual transmission. Instead, it uses a pulley and belt system to vary the gear ratios continuously.

2023年9月23日 · CVT变速箱，也称为无级变速器，其工作原理是通过改变主动齿轮和从动齿轮的半径比来改变传动比。 CVT变速箱的优点在于传动平稳，油耗低，且可以在一定范围内实现无级变速。 然而，CVT变速箱也有一些不足之处，如加速性能相对较差，承受扭矩有限。 适用场合：CVT变速箱适用于注重经济性和舒适性的车型，如小型车、轿车和部分SUV。 3. DCT变速箱，也称为双离合变速器，其工作原理是利用两套离合器交替工作来实现变速。 DCT变速箱的 …

2025年2月6日 · A CVT, or continuously variable automatic transmission, is a type of automatic transmission that typically uses pulleys and either a belt or chain—as opposed to gears—to transfer the engine's ...

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. [1] This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.

2021年10月15日 · How a CVT Works. A CVT uses a simple pulley system rather than the planetary gears that can be found in a traditional automatic transmission. The CVT has an input pulley, an output pulley, and a belt connecting the two pulleys. These are conical pulleys with variable diameters.

In this article, we'll explore how a CVT works in a typical rear-wheel driven car, answering several questions on the way: How does a CVT compare to a conventional, planetary automatic transmission? What parts does it have and how do those parts work? What advantages do CVTs offer over conventional automatic transmissions? What about disadvantages?

CVT结构比传统变速器简单，体积更小，它既没有手动变速器的众多齿轮副，也没有自动变速器复杂的行星齿轮组，它主要靠主、从动轮和金属带来实现速比的无级变化。 因此，CVT带给驾驶员的更多感受就是平顺，没有突兀的顿挫感，同时经济节能，油耗低，但牺牲了驾驶乐趣。 过去CVT的传动带很容易损坏，不能承受较大的载荷，只能限用于在1升排量左右的低功率和低扭矩汽车。 但是近年来随着工艺的不断升高，以及发动机的自我保护技术，CVT逐步应用到了2.0L、2.4L的 …

2024年12月17日 · A CVT—or Continuously Variable Transmission—is a type of automatic gearbox that doesn’t rely on fixed gears like traditional transmissions. Instead of shifting from one gear to another (like 1st to 2nd or 3rd), it seamlessly adjusts its “gear ratio” to match your speed and driving conditions.

Vehicle with continuously variable transmission (CVT) more popular in recent years and Japanese automobile companies are good at using this technology in their vehicles. CVT is a simple and amazing mechanism that offers infinite gear ratios.

2023年10月11日 · A Continuously Variable Transmission, commonly known as a CVT, is an innovative type of automatic transmission system found in many modern vehicles. Unlike traditional automatic transmission systems in Automobile, which rely on a fixed set of gears to manage speed and power, CVTs operate on a fundamentally different principle.
