  • Patent number: 12007016
    Abstract: An axle drive for a motor vehicle, comprising an electric machine coupled by a rotor shaft to a transmission for the axle drive, wherein a torque can be transferred from the electric machine to an intermediate shaft with a first gear stage and from the intermediate shaft to another gear train, in particular a differential, with a second gear stage, wherein the rotor shaft or a shaft segment coupled to the rotor shaft is supported in a bearing element, wherein a fluid supply is designed to convey a liquid, in particular oil, into an intermediate space between the bearing element and a side shaft on the axle drive through a fluid channel, and from the intermediate space into the rotor chamber in the electric machine.

  • Patent number: 11913527
    Abstract: A gear unit has a differential that comprises two planetary gearsets, a first gearset element of the first planetary gearset is connected to an input shaft and a second gearset element of the first planetary gearset is connected to a first output shaft. A third gearset element of the second planetary gearset is connected to a second output shaft. A first output torque is transmittable to the first output shaft by the first planetary gearset. A reaction torque of the first planetary gearset is transmittable to the second output shaft. Between the first output shaft and second output shaft is an actuation mechanism having a first friction partner and a second friction partner. The friction partners generate a connection between the two output shafts when the actuation mechanism is actuated.

  • Patent number: 11846346
    Abstract: A gear unit includes an input shaft, output shafts and a differential having two planetary gearsets with a plurality of gearset elements. A first gearset element is connected to the input shaft, a second gearset element is connected to the first output shaft, and a third gearset element is connected to a gearset element of the second planetary gearset. A second gearset element of the second planetary gearset is connected to a housing, and a third gearset element of the second planetary gearset is connected to the second output shaft. A first output torque transmittable to the first output shaft. The gearset elements of the first planetary gearset and second planetary gearset have a helical toothing such that a torque is transmittable between the two output shafts.

  • Publication number: 20230286376
    Abstract: A gear unit has a differential with two planetary gearsets and gearset elements. A first gearset element of the first planetary gearset is connected to an input shaft, a second gearset element of the first planetary gearset is connected to a first output shaft, a third gearset element of the first planetary gearset is connected to a first gearset element of the second planetary gearset, a second gearset element of the second planetary gearset is connected to a housing, and a third gearset element of the second planetary gearset is connected to a second output shaft. A first output torque is transmittable to the first output shaft. A second output torque is transmittable to the second output shaft. An actuation mechanism is arranged between the first and second output shafts for a co-rotationally fixed connection between the output shafts when the actuation mechanism is actuated.
