The invention relates to an electric drive axle. In one example, an electric drive axle includes an electric machine rotationally coupled to a transmission including a higher range planetary gear set coupled to a lower range planetary gear set via a clutch. The clutch is configured to selectively rotationally couple the input gear to the sun gear in each of the higher range planetary gear set and the lower range planetary gear set at different positions, or selectively rotationally coupling the planet carrier in the higher range planetary gear set to the planet carrier of the lower range planetary gear set and the sun gear in different positions. Furthermore, the invention relates to a method for operating an electric drive axle.

    本发明涉及一种电驱动桥。在一个示例中,电驱动桥包括旋转联接到变速箱的电机,该变速箱包括经由离合器联接到较低范围行星齿轮组的较高范围行星齿轮组。离合器构造成在不同位置将输入齿轮选择性地旋转联接到较高范围行星齿轮组和较低范围行星齿轮组中的每个组中的太阳齿轮,或者在不同位置将较高范围行星齿轮组中的行星架选择性地旋转联接到较低范围行星齿轮组的行星架和太阳齿轮。另外,本发明还涉及用于电驱动桥的操作的方法。
