Abstract: An electric drive system for a motor vehicle includes a first electric machine with a first rotor, a second electric machine with a second rotor, and a reduced coupling gearing, which has a first planetary gear set, a second planetary gear set, a first input shaft, a second input shaft, a first output shaft, and a second output shaft. The first input shaft introduces first torques emanating from the first electric machine into the reduced coupling gearing. The second input shaft introduces second torques emanating from the second electric machine into the reduced coupling gearing. The first output shaft diverts third torques from the reduced coupling gearing. The second output shaft diverts fourth torques from the reduced coupling gearing.

Abstract: An axial flow machine for a motor vehicle includes a stator having two rotors that can be rotated in relation to the stator. The stator is arranged between the rotors in the axial direction of the axial flow machine. The rotors are connected to each other in a rotationally fixed manner by means of respective toothings of the rotors, said toothings being arranged on sides of the rotors facing towards each other in the axial direction.

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: A hybrid drive system includes an internal combustion engine having a first output shaft, an electric machine having a rotor with a rotor shaft as second output shaft, and a transmission having a four-shaft, first planetary set, a second planetary set, a first shifting element, a second shifting element, a third shifting element, and a third output shaft. The four-shaft, first planetary set has a first shaft, a second shaft, a third shaft, and a fourth shaft, the second planetary set has a first element, a second element, and a third element. The first shaft, the second shaft, the third shaft, and the fourth shaft are rotatable relative to one another and connectable to one another in a rotationally fixed manner by a blocking shifting element. The first output shaft is coupled or is couplable to the first shaft in a rotationally fixed manner.
