变速箱的种类有哪些？

What are the types of transmissions?

　　变速箱大致有手动变速箱、普通自动变速箱/普通自动变速箱带手自一体、CVT无级变速箱/CVT带档位的变速箱、双离合变速箱、序列变速箱等类别。

There are various types of transmissions, including manual transmissions, regular automatic transmissions/automatic transmissions with manual transmission, CVT continuously variable transmissions/CVT transmissions with gears, dual clutch transmissions, and sequential transmissions.

　　变速箱主要指的是汽车的变速箱，它分为手动、自动两种，手动变速箱主要由齿轮和轴组成，通过不同的齿轮组合产生变速变矩;

The gearbox mainly refers to the gearbox of a car, which is divided into manual and automatic types. The manual gearbox is mainly composed of gears and shafts, which generate variable speed and torque through different gear combinations;

　　而自动变速箱AT是由液力变扭器、行星齿轮、液压变距系统和液压操纵系统组成。变速箱是车辆上非常重要的部件，它可以改变传动比，扩大驱动轮转矩和转速的作用。

The automatic transmission AT is composed of a hydraulic torque converter, planetary gears, hydraulic pitch control system, and hydraulic control system. The gearbox is a very important component in vehicles, which can change the transmission ratio, expand the torque and speed of the driving wheels.

　　随着现代科技的发展，变速箱也有了升级，从初的手动变速箱，到现在无级变速箱，从无同步器到有同步器，操控越来越方便。

With the development of modern technology, transmissions have also been upgraded. From manual transmissions to continuously variable transmissions, from no synchronizers to synchronizers, control has become increasingly convenient.

　　目前工程机械上广泛采用柴油机，其转矩与转速变化范围小，不能满足车辆在各种工况下对牵引力和行驶速度的要求，需采用变速箱来这种矛盾。变速箱性能的优劣是衡量工程机械动力性、经济性及驾驶性的关键。目前的变速系统主要有机械传动、液力传动、静液压传动。变速箱有人力换挡和动力换挡，结构有定轴式和行星式。

At present, diesel engines are widely used in construction machinery, with a small range of torque and speed changes, which cannot meet the traction and driving speed requirements of vehicles under various working conditions. A gearbox is needed to solve this contradiction. The performance of the gearbox is the key to measuring the power, economy, and driving performance of construction machinery. The current transmission systems mainly include mechanical transmission, hydraulic transmission, and hydrostatic transmission. The gearbox has manual and power shifting, and its structure includes fixed shaft and planetary types.
