ABSTRACT:
A ratio control mechanism for a variable ratio friction drive transmission has an adjustable torus member. The friction drive transmission includes input and output friction members which are frictionally drive connected by the torus member. The central or major axis of the torus member is controlled angularly relative to the input and output friction members by a four-bar linkage. Angular adjustment of the torus member causes a speed ratio change between the input and output members.
