ABSTRACT:
A toroidal type continuously variable transmission includes first and second parallel toroidal transmission units which are both mounted on a common center transmission shaft. The center transmission shaft is axially movable, and the input cone disc of each transmission unit is mounted on the center transmission shaft through ball splines in such a manner as to enable both the torque transmission and relative axial motion therebetween. Therefore, the center transmission shaft transmits, from the input disc of the first unit to the input disc of the second unit, not only an input torque inputted to the input disc of first unit through a loding cam mechanism, but also the an axial thrust load produced by the loading cam mechanism.
