Development of Belt µ Saturation Detection Method for V-Belt Type CVT

This paper describes the development of a detection system of maximum force for a metal belt type CVT. By detecting the occurrence of a macro slip between a belt and pulleys in its early stage, the maximal point of the friction force can be detected while the belt is still running with sufficient clamping force. The ability of the detection system was examined using an experimental test rig of a continuously variable unit.
