    • A multiple substantially identical countershaft powershift transmission is provided. The transmission (10) comprises an input shaft (12) and preferably three (16. 18 and 20) input gears and an output gear (22) concentric and rotatable relative thereto. A plurality of substantially identical countershaft assemblies (42, 42A) carrying countershaft gears (54, 56, 58 and 60) constantly meshed with the input gears and output gear surround the input shaft and an output shaft (24) generally coaxial with inpout shaft (12) and carrying the output gear (22) rotationally fixed thereto are provided. A first double acting friction clutch mechanism (26) for selectively frictionally coupling first speed input gear (16) or third speed input gear (18) to the input shaft and a second double acting friction clutch mechanism (28) for selectively coupling second speed input gear (20) or fourth speed output gear (22) are provided and are concentric and driven by the input shaft (12). Means (V, C) are provided for selectively actuating the clutch portions (30, 32, 36 and 38) of the double acting clutch assemblies with overlapping engagement of the clutch portion being released and the clutch portion being applied.
    • 提供了多个基本相同的中间轴动力换档变速器。 变速器(10)包括输入轴(12),优选地包括三个(16,18和20)个输入齿轮和一个同心且可相对于其旋转的输出齿轮(22)。 多个基本上相同的中间轴组件(42,42A),其承载与输入齿轮和输出齿轮恒定啮合的中间轴齿轮(54,56和58),所述中间轴齿轮围绕输入轴和大体上与输入轴(...)共轴的输出轴(24) 12)并且输送旋转地固定在其上的输出齿轮(22)。 第一双作用摩擦离合器机构(26),用于选择性地将第一速度输入齿轮(16)或第三速度输入齿轮(18)摩擦地联接到输入轴,以及第二双作用摩擦离合器机构(28),用于选择性地将第二速度输入 齿轮(20)或第四速输出齿轮(22),并且由输入轴(12)同心并驱动。 装置(V,C)用于选择性地致动双作用离合器组件的离合器部分(30,32,36和38),该离合器部分被释放的离合器部分和被施加的离合器部分重叠接合。
