The design, the construction and the experimental characterization of a Continuously Variable Transmission (CVT) based on the rolling contact between conical bodies are analyzed. The studied CVT has been developed in order to allow a wide ratio range (up to 9), high torque capability (up to 500 Nm) and compactness. The main design problems and related solutions are explained focusing on the following aspects: contact area optimization, modular approach and development of different CVT versions to meet the current powertrain market needs. A total mechanical efficiency from 82% to 91% has been measured through experimental testing on a prototype.
