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

Abstract: Pulley-torsional damper integrated group comprising a hub adapted to be rigidly connected to a drive member and a pulley connected to the hub. The hub comprises an inner tubular wall and an outer tubular wall. The pulley is angularly coupled to said hub by means of the ring made of elastomeric material. The elastomeric ring has an outer surface towards the pulley and an inner surface towards the hub, and an adhesive is arranged on at least one of the outer or inner surfaces.
