    • A powertrain (200) includes an engine (110) and a continuously variable transmission (208) including a planetary gear arrangement (320) and a variator (310). An input drives the variator (310) and the planetary gears. A first planetary output gear (348) is connected to the first output of the planetary gear arrangement (320). A second planetary output gear (350) is connected to the first output, and a third planetary output gear (352) is connectable by a first clutch (360) to a second output of the planetary gear arrangement (320). A first output member (326) is connected to the third planetary output gear (352), a second clutch (362) releasably connects the first output member (326) with the first planetary output gear (348), a third clutch (364) connects the first output member (326) with the second planetary output gear (350), a fourth clutch (366) connects the second output member (326) with the first planetary output gear (348), and a fifth clutch (368) connects the second output member (326) with the second planetary output gear (350).
    • 动力总成(200)包括发动机(110)和包括行星齿轮装置(320)和变速器(310)的无级变速器(208)。 输入驱动变速器(310)和行星齿轮。 行星齿轮装置(320)的第一输出端连接有第一行星齿轮(348)。 第二行星齿轮(350)连接到第一输出端,​​第三行星齿轮(352)可由第一离合器(360)连接到行星齿轮装置(320)的第二输出端。 第一输出构件(326)连接到第三行星齿轮(352),第二离合器(362)可释放地连接第一输出构件(326)与第一行星齿轮(348),第三离合器(364) 将第一输出构件(326)与第二行星齿轮(350)连接,第二离合器(366)将第二输出构件(326)与第一行星齿轮(348)连接,第五离合器(368) 第二输出构件(326)与第二行星齿轮输出齿轮(350)连接。
