Abstract:
A continuously variable transmission having a longitudinal axis, comprising;a plurality of speed adjusters, each having a tiltable axis of rotation, and each speed adjuster located radially outward from the longitudinal axis; a drive disk annularly rotatable about the longitudinal axis and contacting a first point on each of the speed adjusters and having a first side facing the speed adjusters and a second side facing away from the speed adjusters; a driven disk annularly rotatable about the longitudinal axis and contacting a second point on each of the speed adjusters; a generally cylindrical support member annularly rotatable about the longitudinal axis and contacting a third point on each speed adjuster; a bearing disk annularly rotatable about the longitudinal axis, and adapted to provide rotational force to the drive disk; 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 improving the contact of the drive disk and the speed adjusters.
