In a transmission arrangement including a continuously variable toroidal drive mechanism, an intermediate planetary gear train and a final planetary gear train which are arranged in the power path between an input shaft and an output shaft, a central intermediate shaft is connected to the input shaft and to a central 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, is connected to a central driven disc of the toroidal drive mechanism and to a sun gear of the intermediate gear train. The concentric intermediate shaft has a drive connection to a first mechanism link of the final gear train in the form of a sun gear. An outer ring gear of the intermediate gear train has a drive connection to a second mechanism link of the final gear train. A third mechanism link of the final gear train is mounted on a housing part. A fourth mechanism link of the final gear train has a drive connection to the output shaft, this arrangement providing for high efficiency with a coaxial arrangement of the transmission components.
