Improved filtering pulley for a heavy vehicle

A filtering pulley comprising:

• a hub, which is designed to be fixed to a rotary shaft rotating around an axis (A), and
• a crown, which is coaxial to said hub, said hub defining a tubular portion and at least one connection portion, which is configured to connect said hub to said rotary shaft, said crown defining a radial outer surface defining at least one profile, which is configured to cooperate with a mechanical transmission element, and a radial inner surface, which is radially arranged on the inside relative to the said radial outer surface,
• said filtering pulley comprising:
• a filtering assembly operatively interposed between said hub and said crown and comprising a housing integral to said crown and carried so that it can freely rotate relative to said hub by means of support means, said filtering assembly defining a space and comprising elastic means, which are housed inside said space in a movable manner, and actuator means, which are configured to cooperate in contact with said elastic means,
• said actuator means being manufactured as one single piece together with said tubular portion of said hub and said housing cooperating in contact with said radial inner surface of said crown.
