Abstract

The invention relates to a transmission (100) for a hybrid drive arrangement which can be coupled to two drive assemblies (7, 8), comprising an input shaft (10), and an output shaft (11), at least one first, second, third and fourth shifting element (SE1, SE2, SE3, SE4), and at least one first planetary gear (5) and one second planetary gear (6). The input shaft (10) can be coupled to the ring gear planet carrier of the first planetary gear (5) by means of the first shifting element (SE1) and the output shaft (11) is coupled to the planet carrier of the first planetary gear (5). The planet carrier of the first planetary gear (5) can be coupled to the ring gear of the second planetary gear (6) by means of the second shifting element (SE2) and the planet carrier of the first planetary gear (5) can be coupled to the sun gear of the second planetary gear (6) by means of the third shifting element (SE3). The sun gear of the first planetary gear (5) can be coupled to the sun gear of the second planetary gear (6) by means of the fourth shifting element (SE4).
