Abstract
Hybrid transmission (18) for a motor vehicle powertrain (12) of a motor vehicle (10), comprising: a first transmission input shaft (24) for connecting the hybrid transmission (18) to an internal combustion engine (16) of the motor vehicle; a second transmission input shaft (26) for connecting the hybrid transmission (18) with a first electric drive motor (14) of the motor vehicle; an output shaft (28) for connecting the hybrid transmission (18) with an output (32); a planetary gear set (RS) connected to the first transmission input shaft (24), is not switchably connected to an intermediate shaft (30) and the output shaft (28); Spur gear pairs (ST1, ST2, ST3) arranged in several gear set planes to form gear steps; and several gearshift devices with shifting elements (A, B, C, D, E) for engaging gear stages, wherein the first transmission input shaft (24) is effectively connected to the planetary gear set (RS) by means of a first spur gear pair (ST1) of the spur gear pairs to form gear stages; the second spur gear pair (ST2) is assigned to the output shaft (28) and the first transmission input shaft (24); and the third spur gear pair (ST3) is assigned to the intermediate shaft (30) and the first transmission input shaft (24), wherein the first electric drive motor (14) is connected to the hybrid transmission (18) on a transmission side opposite a connection side of the combustion engine (16); Starting from a connection side of the first electric drive motor (14) and / or the combustion engine (16), the third spur gear pair (ST3), the second spur gear pair (ST2), the planetary gear set (RS), and the first spur gear pair (ST1) are arranged in this order; and / or the output (32) is arranged in a transmission center of the hybrid transmission (18).
