    • The present invention provides a power train for an automatic transmission of a vehicle, including: an input axle for delivering power from an engine; a main-transmission mechanism (6) having a compound planetary gear unit (4) for outputting the power as four speed ratios; a sub-transmission mechanism (10) having a simple planetary gear unit (8) for increasing a speed ratio which is output from the main-transmission mechanism (6) as the largest speed ratio of the four speed ratios; the main-transmission mechanism (6) including a first friction element (C1) for selectively transmitting the power from the input axle (21) to a first sun gear (12) of the compound planetary gear unit (4), a second friction element (B1) for making a second sun gear (14) of the compound planetary gear unit (4) as an idling element, a third friction element (C2) for selectively transmitting the power from the input axle (21) to a planet carrier (16) of the compound planetary gear unit (4), and a fourth friction element (B2) for operating the sun gear (14) as a reacting force element; and the sub-transmission mechanism (10) including a fifth friction element (B3) for operating a third sun gear (40) of the simple planetary gear unit (8) as the reacting force element.
    • 本发明提供一种用于车辆的自动变速器的动力传动系,其包括:用于从发动机输送动力的输入轴; 具有复合行星齿轮单元(4)的主传动机构(6),用于以四个速比输出功率; 具有简单行星齿轮单元(8)的副变速机构(10),用于增加从所述主变速机构(6)输出的速比,作为所述四速比的最大变速比; 主传动机构(6)包括用于选择性地将动力从输入轴(21)传递到复合行星齿轮单元(4)的第一太阳齿轮(12)的第一摩擦元件(C1),第二摩擦元件 (B1),用于将复合行星齿轮单元(4)的第二太阳齿轮(14)作为空转元件,用于选择性地将动力从输入轴(21)传递到行星架(3)的第三摩擦元件(C2) 以及用于操作作为反作用力元件的太阳齿轮(14)的第四摩擦元件(B2);以及第二摩擦元件(B2) 和副传动机构(10),其包括用于操作简单行星齿轮单元(8)的第三太阳轮(40)作为反作用力元件的第五摩擦元件(B3)。
