The invention relates to a transmission unit (1) for a hybrid motor vehicle (2), comprising a planetary gearing (3), wherein the planetary gearing (3) has a first planetary wheel set (4) and a second planetary wheel set (5), an electric machine, which is coupled with a component part (6) of the planetary gearing (3), and a plurality of switching devices (8, 9, 10, 11), each of which forming a brake or a clutch, and each can be moved between an activated position and a deactivated position. The switching devices (8, 9, 10, 11) are used for switching various transmission ratios acting between an input (13), which can be coupled with an internal combustion engine (12), and an output (14), and/or between the electric machine (7) and the output (14), wherein no more than four switching devices (8, 9, 10, 11) are present for implementing at least two different transmission ratios in a drive state of the internal combustion engine (12), at least one transmission ratio in a drive state of the electric machine (7), and at least one transmission ratio in a recuperation state of the electric machine (7), as a result of their activated and deactivated positions. The invention further relates to a motor vehicle (2) having an internal combustion engine (12) and having said transmission unit (1).

    本发明涉及一种用于混合动力机动车辆(2)的变速器单元(1),所述变速器单元具有:行星齿轮传动装置(3),其中所述行星齿轮传动装置(3)装配有第一行星轮组(4)和第二行星轮组(5);电机(7),所述电机与所述行星齿轮传动装置(3)的部件零件(6)联接;以及多个切换装置(8、9、10、11),所述多个切换装置中的每个切换装置形成制动器或离合器,并且每个切换装置能够在启用位置和停用位置之间移动,其中所述切换装置(8、9、10、11)可操作地安装成用于切换可与内燃发动机(12)联接的输入端(13)与输出端(14)之间和/或所述电机(7)与所述输出端(14)之间的各种传动比,其中存在不超过四个切换装置(8、9、10、11),所述切换装置通过其启用位置和停用位置来实现在内燃发动机(12)的驱动状态下的至少两个不同传动比,在电机(7)的驱动状态下的至少一个传动比,以及在电机(7)的回收状态下的至少一个传动比。本发明还涉及一种具有内燃发动机(12)和所述变速器单元(1)的机动车辆(2)。
