Abstract
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.
