Abstract
A gear-change transmission in which the input shaft is connected to one element of a pair of planetary gear sets together forming a differential distributing the output between two shafts. One element of each of the planetary gear sets is connected to a coupling shaft which can be braked for reversal of the transmission output while another two elements of the planetary gears are coupled together and to one of the output shafts. The remaining element of the second set is connected to the remaining input shaft and a clutch can be energized to block the differential and effectively couple all of these shafts together. The output shafts are selectively coupled to a further shaft through positive gearing upon actuation of switching clutches.
