摘要： PROBLEM TO BE SOLVED: To provide a structure by which the load of a starter motor for starting an engine can be sufficiently reduced and excessive slip is not generated in respective traction parts in a continuously variable transmission apparatus by which a gear change ratio can be changed to infinite.SOLUTION: A controller adjusts a stepping motor for controlling the change gear ratio to a step number for making the change gear ratio of a toroidal type continuously variable transmission a deceleration side from the value capable of making the rotational direction of an output member a stop state while rotating an input member in one direction, when starting the engine. The tilt angles of trunnions supporting the respective power rollers are synchronized with each other. Thereafter, the step number for adjusting the change gear ratio of the toroidal type continuously variable transmission to a desired value is learned based on a learning function.

摘要： PROBLEM TO BE SOLVED: To provide a toroidal type continuously variable transmission, with small and lightweight outer ring of a thrust ball bearing for a power roller brought into contact with a trunnion and transmitting a tangential force acting on the power roller thereto.
SOLUTION: An outer peripheral surface 110 of the outer ring 28 is brought into contact with a contact part 120 of the trunnion 15 to transmit the tangential force acting on the power roller 11 to the trunnion 15. A raceway groove 28f for rolling elements 26 of the thrust ball bearing 24 is formed in an inner surface 28d of the outer ring 28. A crowning surface 111 is formed on an outer surface 110 of the outer ring 28 so that a middle portion between the inner surface 28d and the outer surface 28e of the outer ring 28 is high. A top position of an outermost peripheral side of the crowning surface 111 is on an outer surface 28e side of the outer ring 28 than a deepest position of the raceway groove 28f of the outer ring 28. Thereby, increase in stress at a corner part made by the outer peripheral surface 110 and the inner surface 28d of which the wall thicknesses in a radial direction are reduced by the raceway groove 28f of the outer ring 28 is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a structure capable of increasing the usable range of an axial side surface of an output side disk 8a, and increasing the adjustable range of gear ratio in a toroidal continuously variable transmission.
SOLUTION: Both end surfaces in the axial direction of the output side disk 8a are abutted against a pair of thrust raceway rings 25b, 25b constituting a pair of thrust angular ball bearings 11a, 11a arranged in both sides in the axial direction of the output side disk 8a so that the axial dimension of the output side disk 8a is limited. A radial position of a hollow rotating shaft 27 is limited by both thrust raceway rings 25b, 25b. The radial position of the output side disk 8a which is externally fitted into the hollow rotating shaft 27 is limited by limiting the radial position. By this constitution, rigidity in both the ends in the axial direction of the output side disk 8a is enhanced, and the usable range is increased as a traction surface, and thus the above problem is solved.
