Ⅰ、自动变速箱最近几年,由于装有自动变速箱的车辆比直接传动的车辆在运转操作方面的简化和各种技术先进性,所以在欧美很流行。一般的所谓自动变速箱,就是以液压和气压操纵变速代替手动操纵变速的变速箱。有的把液力变矩器考虑在内,称为液力机械传动。在本文中,把装有液力变矩器和自动变速箱的车辆都称为自动变速传动车
I. Automatic transmissions In recent years, vehicles equipped with automatic transmissions have become popular in Europe and the United States due to the simplification of operation and various technological advancements over direct-drive vehicles. The so-called automatic transmission is a hydraulic transmission and a pressure-operated transmission instead of a manually-operated transmission. Some consider hydraulic torque converters as hydraulic mechanical transmissions. In this article, vehicles equipped with torque converters and automatic transmissions are called automatic transmissions.
