Abstract
A power transmission belt formed with an encoder on its surface, method of manufacturing the power transmission belt, and a load detection system using the power transmission belt. The power transmission belt comprises a band-like magnetic rubber layer provided in a part of a belt layer structure of the power transmission belt which transmits power to an auxiliary machine of an automobile engine along the longitudinal direction of the belt layer structure. The surface of the magnetic rubber layer constitutes a multipolar magnetized surface alternately provided with N-poles and S-poles along the longitudinal direction of the belt layer structure, the surface of the magnetic rubber layer is capable of outputting signals for calculating load applied to the belt layer structure by the auxiliary machine to a plurality of magnetic sensors provided along the longitudinal direction of the belt layer structure, and one of the sensors is provided at a position where the auxiliary machine is provided.
