Embodiment Construction
[0031] The same reference numbers in the figures designate the same or similar elements.
[0032] Figure 1a A schematic representation of a motor vehicle drive train with a transmission arrangement 10 according to the invention in a first preferred embodiment is shown. The drive train has two drives. The first drive device 20 is designed as an internal combustion engine whose crankshaft 22 is connected via a spur gear stage 24 to the input shaft of the internal combustion engine of the transmission device 10 . A person skilled in the art will understand that the connections shown via simple spur gear stages are purely exemplary and have no significant significance for the invention.
[0033] The second drive device 30 is designed as an electric motor, which can be operated not only as an electric motor but also as a generator. In the case of the embodiment shown, the electric machine 30 has an outer stator 31 and an inner rotor 32 rotatable relative to the stator 31 . Its ...

The invention relates to a transmission arrangement for a hybrid motor vehicle, comprising - an internal combustion engine input shaft (1) for connecting the transmission arrangement (10, 10') to an internal combustion engine (20) of the motor vehicle, -an electric motor input shaft (2) for connecting the transmission arrangement (10) to an electric machine (30) of the motor vehicle, - an output shaft (3) for connecting the transmission arrangement (10) to an output of the motor vehicle, - a planetary set which is arranged in a housing (42), with a first sun (101), a second sun (102), a first internal gear (201) and a spider (300), on which a set of first planets (310) and a set of second planets (312) are mounted rotatably, wherein the first planets (310) mesh on one side with the first internal gear (201) and on the other side with the second planets (312), the second planets (312) mesh with the second sun (102), and the first sun (101) is connected to the first planets (310) via a tooth engagement mechanism (38, 40) in a torque-transmitting manner, and - a plurality of shifting elements (S1, S2, S3), by means of which elements of the planetary set are coupled switchably among one another or to the housing (42). The invention is characterized in that a set of third planets (321) and a set of fourth planets (320) are mounted rotatably on the spider (300), wherein the third planets (321) mesh on one side with a third sun (103) and on the other side with the fourth planets (320), and the fourth planets (320) for their part mesh with a second internal gear (202), wherein each of the two internal gears (201, 202) is connected to the output shaft (3) via a dedicated tooth engagement mechanism (38, 40) in a torque-transmitting manner.
