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, fourth, fifth, sixth and seventh shifting element (SE1, SE2, SE3, SE4, SE5, SE6, SE7), and at least one planetary gear (5). The input shaft can be coupled to a first transmission shaft (16) by means of the first shifting element (SE1) and the input shaft can be coupled to a second transmission shaft (17) by means of the second shifting element (SE2), and the first transmission shaft (16) can be coupled to the second transmission shaft (17) by means of the third shifting element (SE3), and the first transmission shaft (16) can be coupled to the sun gear of the planetary gear (5) by means of the fourth shifting element (SE4), the first transmission shaft (16) can be coupled to the ring gear of the planetary gear (5) by means of the fifth transmission shaft (SE5), the second transmission shaft (17) can be coupled to the planet carrier of the planetary gear (5) by means of the sixth shifting element (SE6) and the second transmission shaft (17) can be coupled to the su…
