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 a toroidal continuously variable transmission the amount of traction oil provided to contact areas between the power rollers and the input and output discs is increased as a power to be transmitted is increased. Nozzle holes formed in rockable trunnions of the transmission so that the traction oil ejected from the nozzle holes is sprayed to circumferential positions of inner surfaces of input and output discs that are in contact with peripheral surfaces of power rollers. Transmission efficiency is enhanced while maintaining endurance and reliability without supplying excessive traction oil.

摘要： In the toroidal-type continuously variable transmission, the radial clearance of a second radial needle roller bearing 30 for supporting the power roller 8 on the periphery of the pivot shaft portion 26 of the displacement shaft 7 is set larger than the radial clearance of a first radial needle roller bearing 27 for supporting a support shaft portion 25 on a trunnion 6. By increasing the radial clearance of the second radial needle roller bearing 30 in this manner, an increase in the surface pressures in the contact portions between the rolling surfaces of needle rollers 32, 32 and the inner peripheral surface of the power roller 8 and the outer peripheral surface of the pivot shaft portion 26 can be restricted, thereby enhancing the durability of the toroidal-type continuously variable transmission. Also, by reducing the radial clearance of the first radial needle roller bearing 27, the inclination of the displacement shaft 7 is minimized, thereby stabilizing the rotation speed change operation thereof.
