ABSTRACT:
The continuously variable transmission has a rotating drive unit and driven unit sharing a common axis. Splined drive shafts extend radially from the common axis and are rotatably driven by the drive unit. Drive rollers are splined to the drive shafts so that the drive rollers are shiftable along the length of the drive shafts. The drive rollers transmit power directly to the driven unit in forward drive. The shift of the rollers while in forward drive continuously varies the distance between the rollers and the common axis so that the shift continuously varies the torque drive to the driven unit. All the drive rollers in a plurality are always equidistant from the common axis. Elastohydrodynamic oil may be used between the rollers and the driven unit to prevent metal to metal contact.
Neutralizing the drive can be done by shifting the drive rollers a certain distance from the common axis at which distance the rollers are disengaged from the driven unit. For reversing the drive, continued radial shift brings the rollers into contact with second rollers. The second rollers transmit the power from the drive rollers to the driven unit which causes the driven unit to reverse its direction of rotation.
