The invention relates to a transmission and a drive train for a vehicle, the transmission for a drive train of an at least partially electrically driven vehicle comprising a stepped planetary gear set, a first gear shifting element and a second gear shifting element, the stepped planetary gear set has a first sun gear and a second sun gear, a first ring gear and a plurality of stepped planetary gears rotatably mounted on a first planetary gear carrier, the first ring gear is configured to be drivingly connected to the electric machine, and the first planetary gear carrier is non-rotatably connected to the output shaft of the transmission. The first gear shifting element is configured to fix the second sun gear relative to the housing in the closed state, the second gear shifting element is configured to fix the first sun gear relative to the housing in the closed state, and one of the two gear shifting elements is in the closed state in order to rotationally drive the output shaft. The invention also relates to a drive train comprising such a transmission.

    本发明涉及传动装置和用于车辆的传动系,用于至少部分地电驱动的车辆的传动系的传动装置包括分级式行星齿轮组、第一档位切换元件和第二档位切换元件,分级式行星齿轮组具有第一太阳轮和第二太阳轮、第一齿圈以及多个可转动地支承在第一行星齿轮支架处的分级式行星齿轮,第一齿圈设立成与电机以传动作用的方式连接,第一行星齿轮支架不可相对转动地与传动装置的输出轴连接,第一档位切换元件设立成,在闭合的状态中使第二太阳轮相对于壳体固定,第二档位切换元件设立成,在闭合的状态中使第一太阳轮相对于壳体固定,为了转动驱动输出轴,使两个档位切换元件之一处于闭合的状态中。本发明还涉及传动系,其包括这种传动装置。
