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 plural cavity toroidal transmission is designed to permit transmission of great torque between output side disks and a sleeve while maintaining a thickness of the sleeve. To this end, convex portions are formed on outer surfaces of the output side disks and concave portions are formed on edge portions of both axial ends of the sleeve. By fitting the convex portions into the concave portions, synchronous rotations of the pair of output side disks and transmission of rotation from the output side disks to an output gear can be achieved.

摘要： Improved input and output discs for toroidal type continuously variable transmissions are obtained by select processing techniques to form hardened layers. Processing techniques include, e.g., carburizing, carbonitriding, and high-frequency induction hardening. Shot peening may be used to impart compressive residual surface stress to predetermined disc portions to enhance resistance to cracking.

摘要： A toroidal type continuously variable transmission is arranged to support one disc on the input side, facing a pressure device, on the outer circumference of an input shaft through a needle bearing. The other disc on the input side is supported on the input shaft by means of a spline coupling and a flange. A cam board which constitutes a pressure device is supported on the outer circumference of the input shaft through a ball spline. Disc springs are installed between one face of the cam board and a loading nut. In this way, the number of difficult processing steps and the degree of required precision can be reduced at the same time, hence making it possible to implement the reduction of the manufacturing costs.

摘要： In a toroidal-type continuously variable transmission, there is provided a thrust rolling bearing interposed between a power roller and a trunnion for supporting a thrust-direction load applied to the power roller. The thrust rolling bearing includes a plurality of rolling elements and a retainer rollably holding the plurality of rolling elements. The retainer defines a circular-ring-shaped main body and a plurality of pockets respectively formed in the main body for rollably holding the plurality of rolling elements. A clearance between the pocket and the rolling element is set in the range of 0.6 to 6.0% of the ball diameter of the rolling element.

摘要： A sufficient quantity of lubricating oil can be sent into a radial needle bearing and a thrust ball bearing supporting a power roller. The lubricating oil is discharged into a gap space through a send-in side oil supply path formed in a trunnion, and is sent into a receiving side oil supply path in a pivotal support shaft portion. A thrust sliding bearing having a through-hole is provided in the gap space. The downstream end opening of the send-in side oil supply path and the upstream end opening of the receiving side oil supply path are located inside the through-hole.

摘要： The amounts of displacement of trunnions installed in first and second cavities are made equal to each other irrespective of the amount of resilient deformation. Also, if the worst should happen, the stability of the running of an automobile is secured. The supply and discharge of pressure oil to first and second actuators for displacing the trunnions installed in the first and second cavities are effected by first and second control valves independent of each other. A value is included for controlling so that the difference between oil pressure fed into the first actuator and oil pressure fed into the second actuator may not become great.
