The continuously variable gearbox extrudes the metal chain (or rubber belt) through two groups of conical driven plates, so that it is deformed and the transmission ratio of the gearbox is changed.
with this structure, the continuously variable gearbox can obtain countless continuous gears in a certain range, which is beyond the reach of AT gearbox. AT present, the AT gearbox has at most 9 gears.
Therefore, CVT can achieve the best full-time transmission ratio according to the working conditions of engine and automobile, and the fuel economy is guaranteed.
