The invention relates to a hybrid transmission (10) for a motor vehicle powertrain comprising an internal combustion engine (55) and an electric drive machine (18), comprising: a first sub-transmission (10a) with multiple gear stages and a first transmission input shaft (12); a second sub-transmission (10b) with multiple gear stages and a second transmission input shaft (14); a countershaft (16); multiple shift elements (A, B, C, D, E) for engaging the gear stages (1, 2, 3, 4, 5); and gear pairs of idle gears (28, 32, 36, 40, 44) and fixed gears (26, 30, 34, 38, 42), said gear pairs being arranged on multiple gear set planes, in order to form the gear stages, wherein some of the gear stages can be engaged for the internal combustion engine and some of the gear stages can be engage for the electric drive machine; and the gear pairs are paired with the first sub-transmission in a fixed manner in order to form the gear stages with the lowest and second lowest gear ratio. The invention additionally relates to a motor vehicle powertrain comprising such a hybrid transmission.
一种用于具有燃烧动力机器(55)和电驱动机器(18)的机动车辆动力传动系的混合动力变速器(10),混合动力变速器具有:第一子变速器(10a),第一子变速器具有多个挡位级和第一变速器输入轴(12);第二子变速器(10b),第二子变速器具有多个挡位级和第二变速器输入轴(14);副轴(16);用于置入挡位级(1,2,3,4,5)的多个换挡元件(A,B,C,D,E);以及布置在多个齿轮组级别中的、活动齿轮(28,32,36,40,44)和固定齿轮(26,30,34,38,42)的齿轮副,以形成挡位级,其中针对燃烧动力机器可置入挡位级中的一部分挡位级,并且针对电驱动机器可置入挡位级中的一部分挡位级;并且为了形成具有最低的和第二低的传动比的挡位级,齿轮副被固定指配给第一子变速器。本发明还涉及一种具有这种混合动力变速器的机动车辆动力传动系。
