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 and third shifting element (SE1, SE2, SE3), and at least one double planetary gear (5), comprising a first sun gear and a first ring gear and a second sun gear and a second ring gear and a planet carrier. The input shaft (10) can be coupled to the planet carrier of double planetary gear (5) by means of the first shifting element (SE1) and can be coupled to the first sun gear of the double planetary gear (5) by means of the second shifting element (SE2), and can be coupled to the first ring gear of the double planetary gear (5) by means of the third shifting element (SE3) and the output shaft (11) is coupled to the planet carrier of the double planetary gear (5).
