ABSTRACT:
A toroidal traction drive with a pair of spaced discs having opposed annular grooves and mounted in the casing for independent but interrelated coaxial rotation, a plurality of rollers positioned between the discs for frictional engagement with both discs, independent hydraulic control means for shifting each of the rollers with respect to the discs for varying the drive ratio, and a plurality of fixed cam means associated, one with each of the rollers, for bringing the roller axis of each roller to an intersecting relation with the drive axis to establish a steady state condition for the drive.
