Continuously variable traction roller transmissions

U.S. Patent Number: 5803857

Abstract: A continuously variable traction roller transmission includes a safety wire for intersectionally interconnecting first ends of trunnions and for securing simultaneousness and equiphase of inclined rotation of traction rollers about oscillation axes thereof, links for connecting the trunnions, and a link support connected to a transmission casing so as to support the links at a center thereof so that the trunnions make synchronous strokes in the opposite directions along the oscillation axes of the traction rollers. The link support has an end located near the safety wire and formed with a recess to obtain a bifurcated form having leg portions fixed to the casing. The safety wire has an intersection located within the recess.
