Development of auto-tensioner for accessory drive

摘要

Auto-tensioners are used for preventing tension fluctuation or flapping of a belt in serpentine accessory belt drive system. Recently required performance for auto-tensioners are getting high, so, higher damping performance may be expected. In that case, noise may sometimes be heard from an auto-tensioner in some actual conditions. It was effective for noise reduction to improve the sliding friction surfaces which are exciting sources and to prevent diffusion of the noise by adopting a damping mechanism.
