Abstract

The invention relates to a drive assembly for a hybrid vehicle. The drive assembly includes an internal combustion engine input shaft (1) for connecting the drive assembly to an internal combustion engine of a hybrid vehicle; an electric motor input shaft (2) for connecting the drive assembly to an electric machine (80) of the hybrid vehicle; an output shaft (3) for connecting the drive assembly to a slave drive of the hybrid vehicle; a planetary transmission provided with two planetary groups connected via a common bridge portion (30), with the first planetary group being configured as a simple double planetary group; and a plurality of switching elements (61, 62) by means of which components of the planetary transmission are coupled, in a switchable manner, to the input shaft (1, 2) and / or a transmission housing (70). The drive assembly is characterized in that the second planetary group is also configured as a simple double planetary group.

Embodiment Construction

[0057] figure 1 A particularly preferred embodiment of the drive assembly according to the invention is shown. The internal combustion engine input shaft 1 of the shown drive assembly is connected in a manner not shown to a likewise not shown internal combustion engine, in particular to its crankshaft. The drive unit is connected via its electric motor input shaft 2 to an electric motor 80 , which preferably can also be operated as a generator. Via the output shaft of the drive unit, the shown drive unit is connected to a power output (not shown in greater detail), in particular to a differential of the motor vehicle.

[0058] The core section of the drive assembly is formed by a planetary gear consisting of two simple double planetary sets arranged on a common bridge 30 . Further, the first sun element 11 , the first ring gear 21 , the first subset 311 of the first planet wheels and the second subset 312 of the first planet wheels belong to the first planet set. Here, the ...
