Abstract

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.
