Methods and systems are provided for a transmission. In one example, a multi-speed transmission system in an electric vehicle includes a planetary assembly designed to be rotationally coupled to an electric machine and including a first planetary gear set rotationally coupled to a second planetary gear set including a first set of pinions and a second set of pinions. The multi-speed transmission system also includes a first clutch designed to selectively ground a first component in one of the first and second planetary gear sets.

    本发明提供了用于变速箱的方法和系统。在一个示例中,电动车辆中的多速变速箱系统包括:行星组件,该行星组件设计成旋转地联接到电机,并且包括第一行星齿轮组,该第一行星齿轮组旋转地联接到第二行星齿轮组,该第二行星齿轮组包括第一组小齿轮和第二组小齿轮。多速变速箱系统还包括第一离合器,该第一离合器设计成将第一行星齿轮组和第二行星齿轮组中的一个行星齿轮组中的第一部件选择性地接地。
