    • Double-clutch transmission (1) comprises an inner input shaft (20) and an outer input shaft (22) that are connected to a first clutch (8) and a second clutch (10) respectively. A first layshaft (40) and a second layshaft (50) of the DCT (1) are spaced apart and arranged in parallel to the input shafts (20, 22). Gearwheels of the DCT are arranged on the first layshaft (40), on the second layshaft (50), on the inner input shaft (20) and on the outer input shaft (22). The gearwheels comprise seven gearwheel groups for providing seven sequentially increasing gears. Each of the gearwheel groups comprises a fixed gearwheel on one of the input shafts (20, 22) that meshes with an idler gearwheel on one of the layshafts (40, 50). A fourth fixed gearwheel (31) meshes with a fourth gear idler gearwheel (63) and a sixth gear idler gearwheel (65). A third fixed gearwheel (25) meshes with a third gear idler gearwheel (62) and a fifth gear idler gearwheel (64).
    • 双离合变速器(1)包括分别连接到第一离合器(8)和第二离合器(10)的内部输入轴(20)和外部输入轴(22)。 DCT(1)的第一副轴(40)和第二副轴(50)间隔开并平行于输入轴(20,22)布置。 DCT的齿轮布置在第一副轴(40)上,第二副轴(50)上,内部输入轴(20)和外部输入轴(22)上。 齿轮包括七个齿轮组,用于提供七个顺序增加的齿轮。 每个齿轮组包括在一个输入轴(20,22)上的固定齿轮,其与一个副轴(40,50)上的空转齿轮啮合。 第四固定齿轮(31)与第四齿轮空转齿轮(63)和第六齿轮空转齿轮(65)啮合。 第三固定齿轮(25)与第三齿轮空转齿轮(62)和第五齿轮空转齿轮(64)啮合。

    • Double-clutch transmission (DCT) (1) comprises an inner input shaft (20) inside an outer input shaft (22). A first clutch disc (8) and a second clutch disc (10) of the DCT (1) are connected to the two input shafts (20, 22) respectively. Pinions (41, 51, 55) are fixed onto three parallel layshafts (40, 50, 38, 90) of the DCT (1) respectively. The gearwheels on the layshafts (40, 50, 38, 90) comprise seven gearwheel groups. Each of the gearwheel group comprises a fixed gearwheel that meshes with an idler gearwheel. A fourth fixed gearwheel (31) on the outer input shaft (22) meshes with the fourth gear idler gearwheel (63) and the sixth gear idler gearwheel (65). In particular, a fifth fixed gearwheel (26) on the inner input shaft (20) meshes with a fifth gear idler gearwheel (64) and the seventh gear idler gearwheel (66). The gearwheels further comprises a reverse gearwheel group that comprises a fixed gearwheel on one of the input shafts (20, 22), meshing with a reverse gear idler gearwheel (37) on one of the layshafts (40, 50, 38, 90).
    • 双离合器变速器(DCT)(1)包括在外部输入轴(22)内部的内部输入轴(20)。 DCT(1)的第一离合器盘(8)和第二离合盘(10)分别连接到两个输入轴(20,22)。 小齿轮(41,51,55)分别固定在DCT(1)的三个平行的副轴(40,50,38,90)上。 副轴(40,50,38,90)上的齿轮包括七个齿轮组。 每个齿轮组包括与惰轮啮合的固定齿轮。 外输入轴(22)上的第四固定齿轮(31)与第四齿轮空转齿轮(63)和第六齿轮空转齿轮(65)啮合。 特别地,内输入轴(20)上的第五固定齿轮(26)与第五齿轮空转齿轮(64)和第七齿轮空转齿轮(66)啮合。 齿轮还包括反向齿轮组,其包括在一个输入轴(20,22)上的固定齿轮,与一个副轴(40,50,38,90)上的倒档齿轮空转齿轮(37)啮合。
