Abstract

A continuously variable transmission (100) having a longitudinal axis, comprising; a plurality of speed adjusters (1), each having a tiltable axis of rotation, and each speed adjuster located radially outward from the longitudinal axis; a drive disk (34) annularly rotatable about the longitudinal axis and contacting a first point on each of the speed adjusters (1) and having a first side facing the speed adjusters and a second side facing away from the speed adjusters; a driven disk (40) annularly rotatable about the longitudinal axis and contacting a second point on each of the speed adjusters; a generally cylindrical support member (18) annularly rotatable about the longitudinal axis and contacting a third point on each of the speed adjusters; a bearing disk (60) annularly rotatable about the longitudinal axis, and adapted to provide rotational force to the disk drive (34), at least two axial force generators, the axial force generators located between the drive disk and the bearing disk, each axial force generator configured to apply a component of an axial force to the drive disk, thereby the contact of the drive disk and the speed adjusters.
