The invention relates to a transmission unit (1) for a hybrid motor vehicle (2), comprising an input shaft (4) that can be connected to an internal combustion engine (3), a planetary gearing (5), which can be coupled to the input shaft (4), the planetary gearing (5) having a first planetary wheel set (6) and a second planetary wheel set (7), a first electric machine (8) the rotor (9) of which is rotationally fixedly coupled to the input shaft (5), a second electric machine (11) which is coupled with a component part (10) of the planetary gearing (5), and no more than four switching devices (12, 13, 14, 15), each of which forms a brake or a clutch, and each can be moved between an activated position and a deactivated position. The switching devices (12, 13, 14, 15) are used for switching various transmission ratios acting between the input shaft (4) and an output shaft (16) and/or between the second electric machine (11) and the output shaft (16). The no more than four switching devices (12, 13, 14, 15) are configured to implement four different transmission ratios in a drive state of the internal combustion engine (3), and two different transmission ratios in a drive state of the second electric machine (11), thereby implementing a serial operation as a result of their activated and deactivated positions. The invention also relates to a motor vehicle (2) comprising 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),该变速器单元包括:输入轴(4),该输入轴可以连接至内燃发动机(3);行星齿轮系(5),该行星齿轮系可以联接至输入轴(4),行星齿轮系(5)具有第一行星轮组(6)和第二行星轮组(7);第一电机(8),第一电机的转子(9)旋转固定地联接至输入轴(5);第二电机(11),第二电机与行星齿轮系(5)的组成部分(10)联接;以及不多于四个的切换装置(12、13、14、15),所述不多于四个的切换装置中的每个切换装置形成制动器或离合器,并且每个切换装置可以在启用位置与停用位置之间移动。切换装置(12、13、14、15)用于切换在输入轴(4)与输出轴(16)之间和/或在第二电机(11)与输出轴(16)之间作用的各种传动比。所述不多于四个的切换装置(12、13、14、15)构造成在内燃发动机(3)的驱动状态下实现四个不同的传动比并且在第二电机(11)的驱动状态下实现两个不同的传动比,从而由于其启用位置和停用位置而实现串行操作。本发明还涉及一种包括所述变速器单元(1)的机动车辆(2)。
