Analysis of Contact and Slip Behavior of Elements in Metal Pushing Belt CVT

Abstract

We developed the thin-film pressure sensor which was improved durability by forming a film with DLC(Diamond-Like Carbon) or TiN(Titanium Nitride). Several sensors were put on the surface of a drive pulley in the pushing metal belt type of CVT, and then the contact and slip behavior between the pulley and elements which the belt consisted of were analyzed. It became possible to quantify the size of active arc area where the slip was generated and the relation of the slip speed versus the clamping force and the CVT transmitting torque.
