摘要： 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.

摘要： A double-cavity half-toroidal type continuously variable transmission comprises an input shaft rotatable by means of a drive source, first and second input disks rotatable integrally with the input shaft, first and second output disks opposed to corresponding input disks, and a hydraulic loading mechanism. The hydraulic loading mechanism includes first and second hydraulic chambers arranged in the axial direction of the input shaft. The first hydraulic chamber is defined by the back surface of the first input disk, an end face of the first disk member, etc. The second hydraulic chamber is defined by the inner end face of the first cylinder, an end face of the second disk member, etc. The first and second hydraulic chambers are simultaneously supplied with pressurized oil by means of a pressure source. Under the pressure of the oil, the first input disk is pressed toward the first output disk, and the second input disk is pressed toward the second output disk through the medium of an interlocking portion.

摘要： In the toroidal-type continuously variable transmission, the torque transmission shaft 15 includes a flange portion 29a formed in one end thereof, while a securing portion 43 is formed in the end-face side half section of the flange portion 29a so as to be able to secure a tool thereto when tightly fastening a loading nut 19 to a external thread portion 40 formed in the torque transmission shaft 15. And, the outer peripheral surface of the securing portion 43 is formed as a polygonally cylindrical shape having four or more flat surfaces. Also, after the torque transmission shaft 15 is heat-carburized and the surface of a cylindrical portion 44 formed in the torque transmission shaft 15 is removed, the external thread portion 40 is worked, which makes it possible not only to secure the hardness of the adjoining portions of the external thread portion 40 but also to control the hardness of the external thread portion 40 itself. Further, branch oil supply passages 39 and 39 used to supply oil to ball splines 17 and 17 are formed at the positions of the torque transmission shaft 15 that are shifted in the axial direction of the torque transmission shaft 15 from the positions of balls 37, 37, which respectively construct the ball splines 17 and 17.

摘要： In the toroidal type continuously variable transmission system 100 incorporating a power roller bearing 11 therein, race grooves 15 and 16 respectively formed in the inner and outer races 35 and 13 of the power roller bearing 11 are respectively structured in such a manner as to have an arc-shaped cross section, and the radii of curvatures of the arc-shaped cross sections of race grooves 15 and 16 are set in the range of 52% to 59% of diameter of a rolling ball body which can roll on these race grooves, thereby being able not only to restrict an increase in dynamic torque of the power roller bearing but also to improve life of the power roller bearing.

摘要： A continuously variable transmission of the toroidal type comprises an input disc, an output disc, and a pair of rockable trunnions. A synchronous cable is passed around and between the trunnions, crossing in the shape of the figure "8". The synchronous cable includes a wire rope and a pair of retainers fixed thereto. Each retainer is formed of an arcuate metallic tube attached to its corresponding trunnion. The intermediate portion of the tube other than the opposite end portions thereof in the lengthwise direction is fixed to the wire rope by caulking. The opposite ends of the wire rope are connected by means of one of the retainers under a torsional stress such that the synchronous cable can maintain the 8-shaped form in a free state without the influence of any external force.
