摘要
在近日的德国工程师协会主办的某国际研讨会上，德国老牌变速器制造商ZF正式对外发布了汽车历史上第一款9AT自动变速器，开启了汽车动力传输技术的9挡时代。据了解，此前的8AT变速器使用了4组行星齿轮。这些行星齿轮组分别通过5个换挡机构来分别实现介入与分离，但是我们也清楚地看到，复杂结构的背后，
Very soon it could become a story in the past for the 8AT transmission＇ s extra large volume unable to be widely used in small types of vehicles. The new generation of 9AT transmission has fully taken the appeal for miniaturization into consideration, through changing overall arrangement of gears, which can realize supporting for very compact drive unit with front installation and front driving. Also it can very well support the arrangement of hybrid-drive and vehicle type of four-wheel drive.
