  • Patent number: 12609596
    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.

  • Publication number: 20250309711
    Abstract: An axial flow machine for a motor vehicle has a stator and two rotors that can rotate relative to the stator. The stator is arranged between the rotors in an axial direction of the axial flow machine. Sides of the rotors facing towards each other in the axial direction each have first toothing segments arranged one after the other in a circumferential direction of the axial flow machine and spaced apart from each other, and each have second toothing-free segments, arranged in a circumferential direction of the axial flow machine between the first toothing segments. Second segments of a first of the sides and second segments of the second side are spaced apart from each other in the axial direction so that a respective air gap is arranged in the axial direction between the second segments of the first side and the second segments of the second side.

  • Patent number: 12228198
    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.

  • Patent number: 11137069
    Abstract: A motor vehicle transmission, particularly a multistage transmission, includes at least one switchgear unit which includes two coupling elements. An actuator actuates the switchgear unit and an open-loop and/or closed-loop control unit controls the actuator. An inductive connector unit connects the open-loop and/or closed-loop control unit to the actuator and supplies the actuator with electric energy.
