Abstract:
A continuously variable transmission, comprising:an input disk supported on a rotating shaft so as to be integrally rotatable; an output disk supported on the rotating shaft so as to be relatively rotatable; at least one toroidal cavity formed between respective raceway surfaces of the input disk and the output disk; a group of rollers arranged in the cavity for providing for torque transmission between the input disk and the output disk; a plurality of mechanical carriages for respectively supporting the rollers so as to be rotatable; means for mechanically connecting, in a manner that does not utilize hydraulic actuators for effecting the connecting, the plurality of mechanical carriages to one another; and a hydraulic actuator for collectively applying forces against torque transmission reactive forces respectively received by the rollers to the plurality of mechanical carriages through the connecting means.
