Trends in development, design and calculation of CVT

Abstract

Continuously variable transmissions (CVTs) are applied in an increasing number of vehicles. Large ratio coverage allows for reduced engine speeds, which adds to both highway driving comfort and reduced fuel consumption. It becomes increasingly important to further improve the performance in terms of efficiency, robustness and torque capacity of the CVT. This paper describes trends in development, design and calculation of push belt CVT. It’s foreseen that in not so distant future these power transmission will replace the classical transmission, especially in power transmission in road vehicles.
