The invention relates to a gearbox (G1) for an electric drive train (5), comprising: a main shaft (20) on which a first main gear (21), a second main gear (22) and a third main gear (23) are arranged, the first main gear being rotationally fixed relative to the main shaft; and a countershaft (30) on which are arranged a first pinion (31) which meshes with the first main gear and which is default free to rotate around the countershaft, a second pinion (32) which meshes with the second main gear, and a third pinion (33) which meshes with the third main gear. The gearbox further comprises a first coupling member (40) arranged along the countershaft (30) and movable between an engaged position, in which the first coupling member rotationally couples the first pinion (31) with the countershaft (30), and a neutral position, in which the first pinion is rotatable about the countershaft. The gearbox further comprises a second coupling member (18) arranged along one shaft (20) of the primary and secondary shafts (20, 30) and movable between a first position in which one (22) of the second and third gears (22, 23) is rotationally coupled with said one shaft (20), a second position in which one (22) of the second and third gears (22, 23) is rotationally coupled with said one shaft (20), and a neutral position in which one (22) of the second and third gears (22, 23) is rotationally coupled with said one shaft (20). The second coupling member is movable between a second position in which the other (23) of the second and third gears (22, 23) is rotationally coupled with the one shaft, and a neutral position in which the second and third gears (22, 23) are rotatable about the one shaft.
本发明涉及一种用于电动传动系(5)的齿轮箱(G1),所述齿轮箱包括:主轴(20),在该主轴上布置有第一主齿轮(21)、第二主齿轮(22)和第三主齿轮(23),该第一主齿轮相对于主轴旋转固定;和副轴(30),在该副轴上布置有与第一主齿轮啮合且默认绕副轴自由旋转的第一副齿轮(31)、与第二主齿轮啮合的第二副齿轮(32)和与第三主齿轮啮合的第三副齿轮(33)。齿轮箱还包括第一联接构件(40),该第一联接构件沿副轴(30)布置并且能够在接合位置和空挡位置之间移动,在该接合位置,该第一联接构件将第一副齿轮(31)与副轴(30)旋转联接,在该空挡位置,第一副齿轮可以绕副轴旋转。该齿轮箱还包括第二联接构件(18),该第二联接构件沿主轴和副轴(20、30)中的一个轴(20)布置,并且该第二联接构件(18)能够在第一位置、第二位置和空挡位置之间移动,在该第一位置中,该第二联接构件将第二和第三齿轮(22、23)中的一个(22)与所述一个轴(20)旋转联接,在该第二位置,该第二联接构件将第二和第三齿轮(22、23)中的另一个(23)与所述一个轴旋转联接,在该空挡位置中,第二和第三齿轮(22、23)可以绕所述一个轴旋转。
