    • A compound transmission (12) including main and auxiliary transmission sections (14,15) having several pin-type, double-acting, self-energizing synchronizer mechanisms (60,62,84). The several synchronizer mechanisms are configured to provide higher self-energizing forces for higher speed reduction ratio gears than for lower speed reduction gears, and to provide higher self-energizing forces for downshifts than for upshifts. The self-energizing forces are provided by improved self-energizing ramp surfaces (29e,29f,29g,29h and (111a,111b,111c,111d) formed in external splines 29 of a shaft 28 and in internal teeth extending radially inward from a shift flange 110. The shift flange carries improved pre-energizer and neutral centering assemblies (120) axially retained by end surfaces (102a,104a) of jaw clutch member (102,104).
    • 一种复合传动装置(12),包括具有多个销型双重作用的自增力同步器机构(60,62,84)的主传动部分和辅助传动部分(14,15)。 多个同步器机构被配置为为较高速度减速比齿轮提供比用于较低速度减速齿轮的更高的自增力,并且与升档相比提供更高的降档自力。 自增力由改进的自增力斜面(29e,29f,29g,29h和(111a,111b,111c,111d)提供,形成在轴28的外花键29中的内齿和从内径向内延伸的内齿 移位凸缘承载由爪式离合器构件(102,104)的端面(102a,104a)轴向保持的改进的预加力器和中心定心组件(120)。
