Abstract: A hybrid drive system includes a first and second spur gear component transmission that drift via a countershaft. A planetary gear set is arranged coaxially to a crankshaft of the internal combustion engine. A first shaft is couplable with the crankshaft. A rotor of the electric motor is couplable with a second shaft. A first input shaft of the first spur gear component transmission is connected, fixed against rotation, with a third shaft. A second input shaft of the second spur gear component transmission is connected, fixed against rotation, with a fourth shaft of the planetary gear set. The first and the second spur gear component transmission each have exactly one spur gear pairing. An interlock switch element for the rotationally fixed connection of two of the shafts of the planetary gear set is arranged between the two spur gear pairings in an axial direction, seen along the input shafts.

Abstract: An electric drive device for a motor vehicle has a housing, a first planetary gearset arranged in the housing and which has a first sun gear as first elements, a first planetary support, and a first gear ring. A second planetary gearset is arranged in the housing and has a second sun gear that is coupled or can be coupled non-rotationally to the first gear ring as second elements and a second planetary support and a second gear ring. The device has an electric motor, which has a stator and a rotor, an input shaft that can be driven by the rotor and is permanently non-rotationally connected to the first sun gear, an output shaft, having a differential transmission, a lateral shaft and having a first switching element, which is provided to connect the first sun gear non-rotationally to the housing. The rotor, the first planetary gearset, the second planetary gearset, and the differential transmission are arranged coaxially to one another.
