摘　　要：双离合器式自动变速器是基于手动变速器发展而来的,其工作原理是通过将变速器挡位按奇、偶数分开布置,分别与两个离合器连接,通过离合器的交替切换完成换挡过程,以实现动力换挡。它综合了AMT的优势和AT动力换挡的优点,具有很好的换挡品质和车辆动力性、经济性,比较适合我国目前以手动变速器占主导地位的情况。Dual-clutch type automatic transmission derives from manual transmission. Its working principle is that the odd gears and the even gears are arranged separately and both are connected with two clutches respectively,gear shifting is realized through alternation of the two clutches,then gear shifting in power is realized.The advantages of AMT and the advantage of gear shifting in power of AT are integrated on it.It has extremely good quality of gear shifting and excellent power performance and fuel economy,and it is suitable to apply in China where manual transmissions are in the dominant position.
