Abstract
A dual-cavity toroidal variator is disclosed herein. The torques from the first and second cavities are balanced by controlling each roller with mechanical devices rather than individually controlling each roller with a hydraulic actuator. The mechanical devices may be balancing mechanisms having a pivotable linking lever (66) by which the roller carrier (40) of the first cavity and the roller carrier (41) of the second cavity are linked.
