Abstract:
1. A variator comprising a housing, a pair of semi-toroidally recessed races each mounted to the housing for rotation about a variator axis, and a roller mounted between the races to transfer drive between them at a variable drive ratio, the variator further comprising: a sun gear between the races; a ring gear between the races, the ring gear being radially outward of the sun gear; a carrier gear which is disposed between the sun and ring gears and meshes with both, and upon which the roller is mounted in a manner which enables the roller to spin about its own axis and to tilt relative to the races to vary the drive ratio; and a control pinion which is disposed between the sun and ring gears and meshes with both, the control pinion being mounted to the housing in a manner which permits the control pinion to rotate freely about a pinion axis which does not move with respect to the housing, thereby enabling roller loads to be delivered to the housing through the pinion axis, the pinion axis being located between the sun gear and the ring gear, the pinion axis being spaced apart from an axis of the sun gear.
