Abstracts: A Continuously variable transmission (CVT) is a transmission which can change steplessly through an infinite number of effective gear ratios between maximum and minimum values. This contrasts with other mechanical transmissions that only allow a few different distinct gear ratios to be selected. In order to enact new regulations for automotive fuel economy and emissions, the continuously variable transmission, or CVT, continues to emerge as a key technology for improving the fuel efficiency of automobiles with internal combustion (IC) engines. CVTs use infinitely adjustable drive ratios instead of discrete gears to attain optimal engine performance. commonly used CVT has many problem like slip, belt failure and difficulty in manufacturing so we adopt new technology which consist a rotating part attach between tapperd pulley. intermediate rotating part is easy to manufacture, has less slip due to rubber coating and few failure.
