1. Transmission arrangement, including a continuously variable toroidal drive mechanism, an intermediate planetary gear train and a final planetary gear train arranged in a power path between an input shaft and an output shaft, comprising:

  • a central intermediate shaft which is connected to the input shaft and to a central toroidal drive disc of the toroidal drive mechanism and to a planet carrier of the intermediate gear train, a concentric intermediate shaft through which the central intermediate shaft extends, which is connected to a central driven disc of the toroidal drive mechanism and to a sun gear of the intermediate gear train, which has a drive connection to a first mechanism link of the final gear train in the form of a second sun gear a first outer ring of the intermediate gear train which has a drive connection to a second mechanism link of the final gear train in the form of a second ring gear a third mechanism link of the final gear train in the form of a planet carrier which is fixed so that it cannot rotate in relation to a non-rotating housing part, and a fourth mechanism link of the final gear train in the form of a third ring gear which has a drive connection to the output shaft.
