Dual-cavity toroidal variator

摘要

The invention is about a dual-cavity toroidal variator. The torques from the first and second cavities are balanced by controlling each roller with mechanical means rather than individually controlling each roller with a hydraulic actuator. The mechanical means may be a balancing mechanims 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.
