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 ...

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.

Description

technical field [0001] The invention relates to a drive assembly for a hybrid vehicle, the drive assembly comprising [0002] - internal combustion engine - the input shaft, which is used to connect the drive assembly with the internal combustion engine of the hybrid vehicle, [0003] - electric motor-input shaft, which is used to connect the drive assembly with the electric machine of the hybrid vehicle, [0004] - the output shaft, which is used to connect the drive assembly with the output of the hybrid vehicle, [0005] - a planetary gear with two planetary sets connected via a common bridge, the first planetary set of which is designed as a simple double planetary set, and [0006] - a plurality of shifting elements, by means of which the elements of the planetary gear are switchably coupled to one another and to the input shaft and / or to the gear housing. Background technique [0007] Within the scope of this description, a simple double planetary set is understood ...
