Abstract
The invention relates to a method for achieving a continuously variable transmission. A power transmission is realized by a drive and driven members creating at least one point of a contact between each other. Each of members may be at least one roller pressed against an opposite members surfaces with virtual surfaces. The method consists in adjustment of movement directions between the surfaces and the roller defined by a first movement vector of the surface relative to contact point, a second movement vector of the roller and a third movement vector of rolling direction of the roller, a steering angle and a correction angle. The steering angle is varied in accordance with a desired transmission ratio and lateral/thrust load on the roller while respecting the deformability of the contact points.
