<p>Provided is a continuously variable transmission comprising: an input link fixedly and externally touching a driving shaft; a pair of driven shafts arranged to be parallel to the driving shaft, and arranged to be parallel to each other; a pair of output links externally touching one ends of the driven shaft when one-way clutches are interposed between the output links and the one ends of the driven shaft; a coupling link having one end link-coupled to the input link when a link pin is interposed between the input link and the one end of the coupling link, and having the other end of which the inner and the outer teeth are engaged with the output links respectively; a pair of output gears fixedly and externally touching the other ends of the driven shaft respectively; and a final output gear fixedly and externally touching a final output shaft arranged to be parallel to the driven shafts, and engaged with the output gears, wherein the link pin is capable of being moved in the rotation radius direction of the input link according to a load. According to the present invention, the coupling link and the output links are coupled to each other like gears, so the continuously variable transmission can be applied to a crane or the like handling a high load. And, according to the present invention, the final output shaft can be continuously driven in one direction at a phase difference of 180 degrees by only one lever crank mechanism, thereby reducing the number of components. In addition, according to the present invention, the central axis lines of the output gears and the output links are parallel to the central axis line of the driving shaft or the driven shafts respectively, thereby preventing expansion in the direction of the central axis line of the driving shaft or the driven shafts. Furthermore, according to the present invention, bearings are not installed between the coupling link and the output links, so a periodic lubrication can be excluded to reduce maintenance costs.</p> |
