As an example, once the pitch radius is small on click here the driving pulley and enormous about the driven pulley, then the rotational speed of your pushed pulley decreases, resulting in a lower “equipment.” If the pitch radius is massive about the driving pulley and modest within the driven pulley, then the rotational speed of the pushed pulley boosts, leading to a better “gear.” Thus, in idea, a CVT has an infinite range of "gears" that it could possibly operate by means of at any time, at any motor or car or truck pace.
