Toroidal continuously variable transmission

摘要

A toroidal continuously variable transmission (CVT) is comprised of first and second pairs of power rollers whose gyration angles are synchronized by first, second and third wires. The first wire is wound in the shape of 8-figure to power-roller supporting members of the first pair of power rollers, and the second wire is wound in the shape of 8-figure to power-roller supporting members of the second pair of power rollers. The third wire is wound around the four power-roller supporting members and fixed to the diagonally-arranged two power-roller supporting members. A pair of guide walls are disposed between the power-roller supporting members of the first pair of power rollers and between the power-roller supporting members of the second pair of power rollers and bend the third wire extending between the first-pair power-roller supporting members and between the second-pair power-roller supporting members toward output discs.
