Toroidal CVT transmissions utilise discs and energy rollers to range the gear ratio continually. By switching the Make contact with radius in between the discs and rollers, this sort of CVT achieves sleek acceleration and effective electric power transfer.
Friction-disk transmissions were Utilized in numerous cars and small locomotives built in the early twentieth century, including the Lambert and Metz vehicles.
