Abstract: The purpose of this study is to investigate influence of the stiffness of V-belt in clamping direction on shifting speed of V-belt type CVT (Continuously Variable Transmission). Model CVT with push and pull type V-belt was prepared with semi-transparent pulleys made of epoxy resin in order to observe the belt behaviour in the pulley groove. The stiffness of the belt in clamping direction was changed to investigate the influence on the shifting speed in which the cross sections of belts were reduced as the alternative types of belts. At the case where the belt pitch radius was increased, the behaviour of elements of the push type V-belt in the pulley groove indicated that the remarkable radial slip between the element and pulley was not occurred. It was suggested that the pitch radius of the belt entering into pulley groove was depended on the deformation of the belt in compression in clamping direction in pulley groove. It was shown that the shifting speed was increased by re ducing the stiffness of belts in clamping direction regardless of the belt type. (More)
