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.
