阅读说明：本技术 变速器组件、机动车辆动力传动系及对其操作的方法 (Transmission assembly, motor vehicle powertrain and method of operating the same ) 是由 S·贝克 F·库特尔 M·韦克斯 J·卡尔滕巴赫 M·霍恩 P·齐默 T·马丁 O·拜 于 2019-10-15 设计创作，主要内容包括：一种用于机动车辆动力传动系(10)的变速器组件(16),变速器组件具有：第一输入轴(24)和第二输入轴(26),第一输入轴与燃烧发动机(12)相连接或可连接,第二输入轴与第一输入轴(24)共轴地布置；输出轴,输出轴藉由第一组可切换的多个第一挡位齿轮组(38,42,44)与第一输入轴(24)相连接并且输出轴藉由第二组可切换的多个第二挡位齿轮组(36,52)与第二输入轴(26)相连接；第一电动机器(56),第一电动机器与第二输入轴(26)相连接；第二电动机器(60),第二电动机器与第一输入轴(24)相连接；以及第一离合器(K1),第一输入轴(24)和第二输入轴(26)是藉由第一离合器相互可连接的。在此,第二挡位齿轮组具有替代性地可切换的两个挡位齿轮组(36,52),借助于第一电动机器(56)藉由这两个挡位齿轮组相应地可设定电动机式的行驶运行,其中变速器组件(16)被设计成使得：在第一离合器(K1)闭合的情况下藉由替代性地可切换的两个挡位齿轮组(36,52)中的一个挡位齿轮组(36)可设定燃烧发动机式的行驶运行。(A transmission assembly (16) for a motor vehicle powertrain (10), the transmission assembly having: a first input shaft (24) connected or connectable with the combustion engine (12) and a second input shaft (26) arranged coaxially with the first input shaft (24); an output shaft connected to the first input shaft (24) by a first set of first switchable gear sets (38, 42, 44) and to the second input shaft (26) by a second set of second switchable gear sets (36, 52); a first electric machine (56) connected to the second input shaft (26); a second electric machine (60) connected to the first input shaft (24); and a first clutch (K1) by which the first input shaft (24) and the second input shaft (26) are connectable to each other. The second gear set has two alternatively shiftable gear sets (36, 52), by means of which an electric-motor drive mode can be set by means of the first electric machine (56), wherein the transmission assembly (16) is designed such that: the combustion engine drive mode can be set by means of an alternatively shiftable one (36) of the two gear wheel sets (36, 52) with the first clutch (K1) closed.)
