A filtering pulley for an accessory drive of an internal combustion engine, having a hub suitable for connection to an engine accessory, an annular crown provided with a profile configured to cooperate with a drive belt, a coil spring able to transmit torque between the crown and the hub, a first carrier constrained to a first end of the spring and a second carrier constrained to a second end of the spring. The annular crown is externally coaxial to the hub and supported in a rotationally free manner on the hub, and each of the carriers is rotationally coupled to both the hub and the crown with a limited possibility of relative rotation with respect to each of them. |
