The purpose of this study is to investigate the effect of protuberance on the power transmission properties of the Continuously Variable Transmissions (CVT) with dry hybrid V-belt under several conditions of speed ratio. The power transmission properties were examined in three conditions of speed ratio (i = 0.5, 1.0 and 2.0) by using three type belts in which the height of the protuberance was 0, 0.06 and 0.09 mm, respectively. Both pulley thrusts on driving and driven pulley and contraction force were measured by using load cells. Rotating speeds of the both pulley shafts and the torque to the both pulleys were measured by speed pickups and torque meters, respectively. To evaluate of the power transmitting properties of the CVT, thrust ratio, conversion ratio, transmitting efficiency and slip ratio were investigated. It was found that the highest maximum thrust ratio, conversion ratio, transmitting efficiency and allowable driving input torque were obtained when protuberant tension member was used with 0.09 mm of height, respectively. In any condition of speed ratio, applying the protuberance on the side sliding surfaces was effective to improve the power transmission properties.
