  • Publication number: 20210025481
    Abstract: A range-change transmission device includes an input shaft, an intermediate shaft, a countershaft, a transmission output shaft, and a first planetary gear set. A first transmission element of the first planetary gear set is permanently coupled to the intermediate shaft in a rotationally fixed manner. A second transmission element of the first planetary gear set is coupled to the transmission output shaft. A first switching unit is provided to arrange a third transmission element of the first planetary gear set to be fixed to the housing in at least one switching position. The range-change transmission device also includes a second planetary gear set. A third transmission element of the second planetary gear set is permanently coupled to the intermediate shaft in a rotationally fixed manner.

  • Publication number: 20200393021
    Abstract: An electric drive for a motor vehicle includes a housing, an output shaft, an electric engine, which has a stator and a rotor rotatable relative to the stator, a planetary gear set arranged in the housing, which has a sun gear, a ring gear and a planetary carrier, which is non-rotatably connected to the output shaft, having a first switching element, by means of which the ring gear can be non-rotatably coupled to the rotor, and a second switching element, by means of which the ring gear can be non-rotatably coupled to the housing. The first switching element and the second switching element are coupled to each other via a first coupling element and thereby can be operated together by a single first actuator common to the first switching element and the second switching element.

  • Publication number: 20190316664
    Abstract: A range-change transmission device includes a main shaft, an output shaft, and a range-change unit. The range-change unit has at least one planetary gearbox, which includes at least one first gearbox element, at least one second gearbox element, and at least one third gearbox element. The range-change unit also has at least one shifting device, which is provided at least for the selective connection of the main shaft to the first gearbox element and/or to the second gearbox element.

  • Patent number: 8707813
    Abstract: In a shiftable twin gear for a twin-clutch transmission and a twin-clutch transmission, to reduce the effort and costs involved in bearing-mounted idler gears, and in order to provide a simplified twin-clutch transmission a bearing sleeve which is non-rotatable with respect to a first gear body and which has a first bearing region for the bearing support of a second gear body is in the form of a separate component which is press-fitted to the first gear body.
