The invention relates to a two-gear transmission (10) for an electrically driveable motor vehicle. The two-gear transmission is provided with an input shaft (12), which is connectable to an electric machine, for introducing a torque; an output shaft (14), which is connectable to a drive wheel, for delivering the torque; a low first gear (16) for transmitting a rotational speed of the input shaft (12) to the output shaft (14) at a first transmission ratio; a high second gear (18) for transmitting a rotational speed of the input shaft (12) to the output shaft (14) at a second transmission ratiolower than the first transmission ratio. The first gear (16) has a first input gearwheel (20) coupled to the input shaft (12) via a freewheel (28), which freewheel (28) locks in a torque-transmittingmanner in the event of overrun of the input shaft (12) and interrupts torque transmission in the event of overrun of the first input gearwheel (20), and the second gear (18) has a second input gearwheel (24) coupled to the input shaft (12) via a centrifugal clutch (38). Accordingly, the two-gear transmission permits comfortable power transmission in an electrically driveable motor vehicle.
提出一种用于可电驱动的机动车的两挡变速器(10),其具有:可与电机连接的输入轴(12),用于导入扭矩;可与驱动轮连接的输出轴(14),用于导出扭矩;低的第一挡位(16),用于将输入轴(12)的转速以第一传动比传递到输出轴(14)上;高的第二挡位(18),用于将输入轴(12)的转速以比第一传动比更小的第二传动比传递到输出轴(14)上,其中第一挡位(16)具有与输入轴(12)经由自由轮机构(28)耦联的第一输入轮(20),其中在输入轴(12)超过时,自由轮机构(28)以传递扭矩的方式锁止,并且在第一输入轮(20)超过时,自由轮机构中断扭矩传递,并且其中第二挡位(18)具有与输入轴(12)经由离心力离合器(38)耦联的第二输入轮(24)。由此,在可电驱动的机动车中能够实现舒适的功率传递。
