ABSTRACT:
A toroidal continuously variable transmission, comprises three circumferentially-spaced friction rollers disposed between and in driving contact with input and output toric discs, and roller carriers rotatably supporting the rollers, repectively. Swing links are rotatably supported by a housing. Each of the swing links having two arms associated with the adjacent two of the carriers. A spherical ring received in a bore of each of the arms is coupled to its associated roller carrier for forming a swivel connection between the arm and the associated carrier. A needle bearing is disposed between the spherical ring and the associated roller carrier for forming a slidable connection between the arm and the associated carrier.
