金属ベルトCVTのエレメント間押し力測定と理論計算との比較

抄録

Metal-belt CVTs are effective in improving fuel efficiency in automobiles，but their own mechanical efficiency is low．Since power transmission is performed by friction between the belt and pulley，it is necessary to clamp the belt with the pulley．Currently，excess clamping force is applied to prevent total slippage，resulting in various power losses. A possible way to reduce these losses is to reduce the clamping force by determining the coefficient of friction in the circumferential direction of the elements．In this study，the circumferential friction coefficients are calculated from the clamping force measured by a push force sensor between elements．The results are compared with theoretical calculations．
