Patent ID: 8708856

Claim:
A continuously variable transmission apparatus, comprising: an input shaft receiving an externally inputted rotational force; a plurality of driven gears which are arranged around the input shaft each with certain phase difference, thus receiving a driving force from the input shaft; a variable cam the rotation radius of which changes by means of an external load; a variable input link receiving a rotational force of the input shaft and engaged to the input shaft in a rotation possible manner; a one direction clutch which receives bidirectional rotational force from the driven gears only in one direction, thus rotating each driven gear in one direction; a plurality of cam shafts which come into inner or outer contact with the one direction clutch; a plurality of output links one end of each of which rotates idle with respect to the rotational center of the variable input link along with the variable cam, and the other end of each of which is rotatably engaged to each cam shaft, with the plurality of the output links having same lengths; and a reaction apparatus for pressing the variable cam with respect to the input shaft in a radial outward direction.
