    • A control system is provided for a multiple clutch transmission (10) having at least three synchronizers (74, 76, 78, 80) with opposed acting alpha and beta pressure chambers (106, 104) to selectively synchronize alpha or beta gears with a rotating shaft. The control system includes a pressure source (124), a sump (120), a first multiplex valve (160) having a first position allowing fluid communication of alpha and beta chambers for two synchronizers (74, 76) with the pressure source (122) and diverting alpha and beta pressure chambers (106, 104) of remaining synchronizers (80, 78) to sump (120). The first multiplex valve (160) has a second position reversing the above action. A second multiplex valve (164) connected with the first multiplex valve (160) having a first position connecting alpha and beta chambers (106, 104) of a given synchronizer with the pressure source (122) and alpha and beta chambers (106, 104) of the other synchronizer with the sump (120). The second multiplex valve (164) has a second position reversing the action. A first regulator valve (170) is connected with the second multiplex valve (164) for selectively connecting the alpha chamber (106) with one of a set of the pressure source (122) and the sump (120). A second regulator valve is provided connected with the second multiplex valve (164) for selectively connecting the beta chamber (104) with one of a set of the pressure source (122) and the (sump 120).
    • 提供了一种用于具有至少三个同步器(74,76,78,80)的多离合器变速器(10)的控制系统,其具有相对的作用α和β压力室(106,104),以选择性地使α或β齿轮与旋转 轴。 控制系统包括压力源(124),贮槽(120),第一多路阀(160),其具有第一位置,允许用于具有压力源(122)的两个同步器(74,76)的α和β腔室的流体连通 并且将剩余的同步器(80,78)的α和β压力室(106,104)转移到贮槽(120)。 第一多路阀(160)具有反转上述动作的第二位置。 与第一复合阀(160)连接的第二多路阀(164)具有将给定同步器的α和β室(106,104)与压力源(122)和α和β室(106,104)连接的第一位置 )与贮槽(120)的另一个同步器。 第二多重阀(164)具有反转动作的第二位置。 第一调节阀(170)与第二多路阀(164)连接,用于选择性地将α室(106)与一组压力源(122)和贮槽(120)中的一个连接。 提供与第二多路阀(164)连接的第二调节阀,用于选择性地将β室(104)与一组压力源(122)和(贮槽120)中的一个连接。
