Abstract

The present invention relates to a multi-stage hybrid powertrain for a motor vehicle, having an input stage, also comprising: a stage input shaft coupleable to an internal combustion engine, a stage output shaft coupled to a subsequent stage, an electric machine with a base fixed stator and rotatably mounted rotor radially inside the stator, and a planetary gear set having a sun, a ring gear and aplanet carrier on which a plurality of planets are rotatably supported, which on the one hand mesh with the sun and on the other hand mesh with the ring gear, wherein the sun is coupled to the rotor,the ring gear is coupled to the stage input shaft and the planet carrier is coupled to the stage output shaft. The invention is characterized in that a first clutch coupling the rotor to the sun is arranged axially adjacent to the planetary gear set, a second clutch coupling the rotor to the stage output shaft is arranged axially adjacent to the first clutch, and the planetary gear set and the clutches are disposed both radially and axially within the rotor.

Description

technical field [0001] The invention relates to a multi-stage hybrid drive train for a motor vehicle, having an input stage and further comprising: [0002] - stage input shafts that can be coupled to internal combustion engines, [0003] - stage output shaft coupled to the following stage, [0004] - an electric machine with a fundamentally fixed stator and a rotor rotatably arranged radially inside the stator, and [0005] - a planetary gear set with a sun gear, a ring gear and a planet carrier on which a plurality of planet gears are rotatably mounted, which mesh with the sun gear on the one hand and with the ring gear on the other hand, [0006] Wherein, the sun gear is coupled with the rotor, the ring gear is coupled with the stage input shaft, and the planet carrier is coupled with the stage output shaft. Background technique [0007] Such a hybrid drive train is known from EP 1 640 202 A1. [0008] In the design of modern hybrid drive trains for motor vehicles, an...
