概要

The influences of lubricants on the torque capacity and transmission efficiency were evaluated by using the commercial CVT unit. Furthermore, in order to analyze the friction characteristics of each contact parts of CVT, a block on disk type friction testing machine was created. As a results, it is found that the maximum torque capacity between the belt and pulley in actual CVT correlated with the friction coefficient under high contact pressure (150MPa) and relatively high sliding speed (0.1 m/s) by the friction test. The measurements of the transmission efficiency of CVT were conducted by varying the thrust force of the secondary pulley and speed ratio with steady oil temperature. The efficiency of transmission decreased under the condition of multiplying speed side at a lower load. The maximum difference of the efficiency among all tested oils reached up to 4%.
