ABSTRACT:
A toroidal transmission, especially for motor vehicles, comprising an input shaft which can be connected to an engine, a first toroidal variator and a second toroidal variator which are connected to the input shaft on the input side. A first output shaft can be connected to the output of the first toroidal variator, and a second output shaft can be connected to the output of the second toroidal variator. The toroidal transmission comprises a first power range shifter for the first toroidal variator and a second power range shifter for the second toroidal variator. The first power range shifter and the second power range shifter have a common clutch.
