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 and sixth shifting element (SE 1 , SE 2 , SE 3 , SE 4 , SE 5 , SE 6 ), and at least one planetary gear ( 5 ). The input shaft ( 10 ) can be coupled to a first transmission shaft ( 16 ) by means of the first shifting element (SE 1 ), the first transmission shaft ( 16 ) can be coupled to the ring gear of the first planetary gear ( 5 ) by means of the second shifting element (SE 2 ), the first transmission shaft ( 16 ) can be coupled to a second transmission shaft ( 17 ) by means of the third shifting element (SE 3 ), the first transmission shaft ( 16 ) can be coupled to the fourth transmission shaft (SE 4 ) by means of a third transmission shaft ( 18 ), the output shaft ( 11 ) can be coupled to the third transmission shaft ( 18 ) by means of the fifth shifting element (SE 5 ) and the output shaft ( 11 ) can be coupled to the planet carrier of the planetary gear ( 5 ). The second transmission shaft ( 17 ) can be coupled to the sun gear of the planetary gear ( 5 ) by means of the sixth shifting element (SE 6 ).
