Abstract: Filtering pullies with a hub adapted to be fixed to a rotating shaft, a crown mounted coaxially and rotationally free on the hub, at least one elastic group arranged circumferentially with respect to the hub and the crown and interposed, each, between a pair of first elements integral with the hub and between a pair of second elements integral with the crown are disclosed. The pulley has a dust protection system configured to isolate the at least one elastic group with respect to the external environment and to provide an axial force generating a damping to the movement between the hub and the crown.

Abstract: A filtering pulley assembly for an accessory drive of a vehicle has a hub fixedly attachable to a rotating shaft, a pulley mounted coaxial and freely rotating on said hub, an actuator disc carried by the hub, a plurality of elastic assemblies interposed between the pulley and the actuator disc, and a torque limiting coupling configured to rotationally connect the actuator disc to the hub, when the torque is below a predetermined threshold value, and to decouple the actuator disc from the hub, when the torque is above the threshold value.
