Abstract
A combined multistage hybrid transmission has a transmission housing; a transmission input shaft; a transmission output shaft; a first planetary gear set with a first sun pinion, a first ring gear, and a first carrier shaft on which at least one first planetary gear is rotatably mounted; a second planetary gear set with a second sun pinion, a second ring gear, and a second carrier shaft on which at least one second planetary gear is rotatably mounted. An electromechanical energy converter is rotationally fixed to the first sun pinion, wherein the first ring gear is rotationally fixed to the second sun pinion by an intermediate shaft. The transmission output shaft is arranged axially parallel and at a radial distance to the transmission input shaft. The drive power can be transmitted from the transmission input shaft by a first spur gear stage with a first transmission input spur gear and a first transmission output spur gear and by a second spur gear stage with a second transmission input spur gear and a second transmission output spur gear. The two transmission output spur gears are concentric to the transmission output shaft and the two transmission input spur gears are concentric to the transmission input shaft. The first transmission input spur gear is or can be rotationally fixed to the intermediate shaft, and the second transmission input spur gear is or can be rotationally fixed to the second ring gear.
