    • The invention relates to a transmission for a motor vehicle, wherein the transmission (10) comprises an input shaft (20) and at least a first and second countershaft (30; 40), and an output shaft (50), wherein the input shaft (20) is provided with a first driving gearwheel (21), which interacts with a first gearwheel (31) arranged upon the first countershaft (30), and a second gearwheel (41) arranged upon the second countershaft (40) wherein the first and second countershaft (30, 40) further is provided with a first and second output gearwheel (32; 42) respectively, which interacts with a common final drive gearwheel (51) arranged upon the output shaft (50). A number of gear teeth (n31) of the first gearwheel (31) is selected such in relation to the number of gear teeth (n21) of the first driving gearwheel (21), that the number of gear teeth (n31) of the first gearwheel (31) can be either reduced or increased with at least one gear tooth, without affecting the number of gears teeth (n21) upon the first driving gearwheel (21), vvhereby the reduction or increase the number of gear teeth (n31) of the first gearwheel (31) is compensated with a profile shift of the gear teeth of the first gearwheel (31).
    • 本发明涉及一种用于机动车辆的变速器,其中变速器(10)包括输入轴(20)和至少第一和第二中间轴(30; 40)和输出轴(50),其中输入轴 (20)设置有与布置在第一中间轴(30)上的第一齿轮(31)相互作用的第一驱动齿轮(21)和布置在第二中间轴(40)上的第二齿轮(41),其中第一 并且第二中间轴(30,40)还分别设置有第一和第二输出齿轮(32; 42),其与布置在输出轴(50)上的公共最终传动齿轮(51)相互作用。 第一齿轮31的多个齿轮齿(n31)相对于第一主动齿轮(21)的齿轮齿(n21)的数量选择为第一齿轮(31)的齿轮齿数(n31) 齿轮(31)可以用至少一个齿轮齿减小或增加,而不影响第一驱动齿轮(21)上的齿轮齿数(n21),通过减少或增加齿轮齿(n31)的数量 第一齿轮(31)由第一齿轮(31)的齿轮的轮廓移位补偿。
