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.
