Abstract
Filtering pulley has a hub adapted to be fixed to a shaft rotating around an axis (A), 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 fixedly carried by hub and between a pair of second elements fixedly carried by crown. The filtering pulley includes a centring member configured to cooperate with the hub and the first elements in order to fix the first elements in a predefined angular position with respect to the hub.
