Methods and systems for an electric drive axle of a vehicle are provided. An electric drive axle system includes, in one example, an electric motor-generator rotationally coupled to a gear train. The gear train includes an output shaft rotationally coupled to a gear assembly axially offset from an input shaft rotationally coupled to the electric motor-generator, where the gear assembly is rotationally coupled to a differential and the differential is rotationally coupled to an axle, a first clutch assembly is configured to rotationally couple and decouple a first gear set from the output shaft, and a second clutch assembly is configured to rotationally couple and decouple a second gear set from the output shaft, the second gear set having a different gear ratio than the first gear set.

    提供了一种用于车辆的电驱动桥的方法和系统。在一个示例中,该电驱动桥系统包括旋转地联接至齿轮系的电动马达‑发电机。该齿轮系包括:输出轴,该输出轴旋转地联接至齿轮组件,与旋转地联接至电动马达‑发电机的输入轴轴向偏置,其中,齿轮组件旋转地联接至差速器,并且差速器旋转地联接至车桥;第一离合器组件,该第一离合器组件构造成将第一齿轮组与输出轴旋转地联接和解除联接;以及第二离合器组件,该第二离合器组件构造成将第二齿轮组与输出轴旋转地联接和解除联接,第二齿轮组具有与第一齿轮组不同的传动比。
