ABSTRACT:
The toroidal continuously variable transmission comprises a drive shaft which is rotationally driven by an engine, an input shaft which is disposed adjacent to and coaxially with this drive shaft, input disk which rotate integrally with the input shaft, output disks which are disposed coaxially with the input disks so as to be capable of rotating relatively thereto and to face the input disks, trunnion assemblies which are clamped between the input disks and the output disks so that these trunnion assemblies are free to swing, a pushing cylinder which pushes the input disks and output disks in the respective directions that cause these disks to clamp the trunnion assemblies, and a coupling mechanism which connects the drive shaft and the input shaft by means of an Oldham coupling.
