Abstract
In a load change-over gear with infinitely variable transmission, which includes a linkage gear (1) driven by a main drive shaft (5), a control gear (2) associated with the linkage gear (1), as well as a switching or change-over gear (4) series-connected after the linkage gear (1), linkage shafts (10 and 11) can be alternately coupled to the switching gear (4). To create a variable switching logic and to save structural components of the switching gear (4), a superposition gear (3) is series-connected after the linkage gear (1) whose input shaft (14) can be coupled alternately to linkage shafts (10 and 11). Superposition gear (3), in which the main drive shaft rpm can be superposed on the rpm of the input shaft (14), in turn includes a linkage shaft (21) that can be coupled directly to a main output shaft (24) or to the switching gear (4).
