Abstract: A motor vehicle transmission includes a toroidal variable-speed drive unit. The drive unit includes at least an input shaft, a hollow shaft, two driving discs, and a driven disc. The two driving discs are connected fixedly in terms of rotation to one another with the input shaft. The driven disc is connected fixedly in terms of rotation to the hollow shaft arranged concentrically to the input shaft. The hollow shaft is supported axially, at least in one direction, with respect to a transmission case by a bearing.

Abstract: A toroidal variable-speed drive unit includes at least one axial offset transmission, at least one actuating member, pivotable supporting journals, and rollers arranged on the pivotable supporting journals which are coupled to one another by the at least one axial offset transmission and can be supported on the at least one actuating member, wherein the rollers are arranged between the actuating member and the at least one axial offset transmission.

Abstract: 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.

Abstract: In a variable-speed transmission arrangement, a continuously variable toroidal transmission and a planetary aggregating transmission are arranged in the power path between an input shaft and a coaxial output shaft. A central intermediate shaft is mounted to the input shaft for rotation therewith and to an input disc of the toroidal transmission. A planet carrier is connected firmly to the central intermediate shaft which passes through a concentric intermediate shaft, to which an output disc of the toroidal transmission and a second transmission member of the output transmission are connected. A third transmission member of the aggregating transmission is connectable to the output shaft, by means of a first clutch in a low mode, and a fourth transmission member of the aggregating transmission is connectable to the output shaft by means of a second clutch in an upper driving mode.

Abstract: A transmission for a motor vehicle, such as a motor vehicle EVT, is configures so that the number of teeth of the first planet gear of the epicycloidal gear train, operatively connected to the output toroidal disks by the first sun gear, and of an output element of the epicycloidal gear train form a ratio not equal to one. The transmission ratio of the toroid variator can be varied in such a way, and the number of teeth of the first planet gear of the epicycloidal gear train and of an output element of the epicycloidal gear train are configured in such a way that an output shaft speed approximating zero can be selected according to the variator.
