Abstract: An output rotational driving power of the engine is split into a first split power and a second split power. The first split power is transmitted to a continuously variable speed transmission that transmits the first split power by a shearing resistance of a fluid. The second split power is transmitted to a differential planetary gear system. An output power of the continuously variable speed transmission is transmitted to the differential planetary gear system to combine the first split power and the second split power in the differential planetary gear system. A variation of a rotating speed of the output rotational driving power is absorbed by the continuously variable speed transmission to adjust an output rotating speed of the differential planetary gear system to a constant speed.

Abstract: In a toroidal type continuously variable transmission, first pivot shafts provided on both ends of first trunnions are supported within support holes formed in yokes secured to an inner surface of a casing. The support portions are provided with ball splines and radial needle bearings. During operation, loads acting on the first trunnions are canceled within the yokes. Axial displacements and rocking displacements of the first trunnions are effected smoothly by the ball splines and the radial needle bearings.
