Hybrid drive assembly for a motor vehicle

A hybrid drive assembly comprising:

• an internal combustion engine as a first drive machine, which has a first drive shaft;
• an electromechanical energy converter as a second drive machine, which has a second drive shaft;
• a switchable traction gear device comprising:
• a first gear input shaft configured to be selectively connected to the first drive shaft;
• a second gear input shaft configured to be connected to the second drive shaft;
• and
• a gear output shaft that is configured to discharge drive power from at least one of the first drive machine or the second drive machine to a remaining motor vehicle drive train,
• wherein the traction gear device is in the form of an epicyclic gear device and has an input planetary gear wheel set, wherein the input planetary gear wheel set has at least three gear shafts, of which one is in the form of an input sun gear shaft and one is in the form of an input ring gear shaft and one is in the form of an input planetary gear carrier shaft,
• wherein a first one of the three gear shafts of the input planetary gear wheel set is the first gear input shaft, and wherein in a torque transmission direction from the first drive shaft to the first gear input shaft, a first torsional vibration reduction device is arranged therebetween,
• wherein another of the three gear shafts of the input planetary gear wheel set is the second gear input shaft, and wherein, in a torque transmission direction from the second drive shaft to the second gear input shaft, a second torsional vibration reduction device is arranged therebetween, and
• wherein the first drive shaft is connected with an internal combustion engine gear stage to the first gear input shaft so that the first drive shaft is arranged axially parallel and radially spaced apart with respect to the first gear input shaft.
