摘要： A range-change transmission device, which is a splitter transmission, includes an input shaft, an output shaft, a countershaft, at least one planetary gear set, and a torque adjustment device. A first transmission element of the planetary gear set is arranged coaxially to the output shaft. A second transmission element of the planetary gear set is or can be directly coupled to the countershaft. A third transmission element of the planetary gear set is permanently coupled to the input shaft in a rotationally fixed manner. The countershaft is or can be coupled to the torque adjustment device. The range-change transmission device has a first switching unit, which is provided to couple the countershaft to the output shaft.

摘要： 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.

摘要： 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.
