1、自动变速箱（AT），这是最常用的类型，市场上绝大部分车型都配备了AT变速箱。AT变速箱的优点包括技术相对稳定、使用范围广泛等。但是，与MT相比，AT的成本较高，开发难度也较大。此外，AT的顿挫感较强，换挡速度也不如其他类型。

1. Automatic transmission (AT) is the most commonly used type, and the vast majority of models on the market are equipped with AT transmissions. The advantages of AT gearbox include relatively stable technology and a wide range of applications. However, compared to MT, AT has higher costs and greater development difficulties. In addition, AT has a strong sense of jerkiness and its shifting speed is not as good as other types.

2、半自动变速箱（AMT），它在操作上类似于MT，但加入了电子控制系统。由于结构比较简单，成本相对较低，因此AMT一度被认为是未来汽车发展的趋势。然而，AMT存在着顿挫感较强等缺点，使得它的发展受到限制。

2. Semi automatic transmission (AMT), which operates similarly to MT but incorporates an electronic control system. Due to its simple structure and relatively low cost, AMT was once considered the trend of future automotive development. However, AMT has drawbacks such as strong jerkiness, which limits its development.

3、双离合变速箱（DCT），也叫做快速换挡变速箱。这种类型的变速箱采用两个离合器，实现了无缝换挡，以及高效率、快速和平稳的驾驶体验。但是，DCT的制造加工要求非常高，故障率也比较高，部分车型有明显的顿挫感。

3. Dual clutch transmission (DCT), also known as quick shift transmission. This type of gearbox uses two clutches to achieve seamless shifting, as well as efficient, fast, and smooth driving experience. However, the manufacturing and processing requirements of DCT are very high, and the failure rate is also relatively high. Some car models have obvious jerkiness.

4、无级变速箱（CVT），它是最新的自动挡变速箱技术之一。与传统变速箱不同，CVT没有固定的齿轮组，而是通过液压和传动带调整转速的方式实现不同挡位的切换。CVT变速箱具有平稳性好的优点，几乎感觉不到一点顿挫感，但由于扭矩有限、维修不太方便，因此在一些车型上应用较少。

4. The continuously variable transmission (CVT) is one of the latest automatic transmission technologies. Unlike traditional transmissions, CVTs do not have fixed gear sets, but switch between different gears by adjusting the speed through hydraulic and transmission belts. The CVT gearbox has the advantage of good stability, with almost no jerky feeling, but due to limited torque and inconvenient maintenance, it is less commonly used in some car models.
