In recent years, the great improvement in the materials for the rolling elements and the development of the new traction oil has increased the reliability of the traction drive CVT (Continuously Variable Transmission) for automotive use. The authors began the research and development of the Half Toroidal CVT in 1978, and have made types of prototypes. Traction coefficient and efficiency were measured and life tests were carried out succesfully. As a result of these studies, we conclude that traction drive CVT has the potential for application to automotive transmission.
