<p>The present invention relates to an infinitely variable transmission which places a driving gear group in parallel with a driven gear group, inserts a bearing into the driving gear group in a geared state, and inserts a bearing into inscribed driving shafts and the driven gear group in order to form all inscribed driven shafts in tubular shafts, inserts a one-way clutch into between the driven shaft and the driven gear group, selectively engages two driving gears with two driven gears engaged with the two driving gears among multiple driving gears because a driving wedge unit and a driven wedge unit of driving/driven engaging clutches on the driving shaft and the driven shaft using a ball screw are moved by a mode switch means driven by a power source in the infinitely variable transmission itself in the shaft line direction synchronously and, thus, transmits driving force of the driving shaft to the driving shaft. The mode switch means comprises: a turning unit which rotates an input screw shaft in the same rotating direction and at the same rotating velocity as the rotating direction and the unchangeable velocity of an input shaft; a relative velocity difference generating unit which rotates normally or reversely an output screw shaft at a higher or slow velocity than the rotating velocity of an output shaft; and a relative velocity difference transmitting unit which transmits the revolutions per minute (RPM) of the output shaft to the input screw shaft as much as the relative velocity difference between the output screw shaft and an output wedge nut.</p> |
