Abstract
A filtering pulley for an accessory transmission of an internal combustion engine has a hub, a crown, a filtering unit for transmitting the torque that is interposed between the hub and the crown, a torsion spring, a carrier, and a torque limiting joint. The torque limiting joint has an open-loop strip spring and is configured to slide with respect to a surface of the crown when the torque transmitted between the crown and the hub reaches a predetermined level.
