1. A filtering pulley comprising:
a hub configured to be fixed to a shaft rotating around an axis,
a crown mounted coaxial and rotationally free on said hub,
a plurality of elastic groups arranged circumferentially with respect to said hub and said crown and interposed, each, between a pair of first elements integral to said hub and between a pair of second elements integral to said crown, said first elements including at least two spokes, carried by an actuator, said actuator including a coupling portion carried by said hub and an actuation portion defining said spokes carried by said crown, said pulley including coupling means configured to allow a selective coupling of said coupling portions and actuation portion to define a first configuration in which they cooperate so that said crown is operationally connected to said hub and a second configuration in which they are operatively separated so that said crown is operationally disconnected from said hub, and
actuating means configured to control said coupling means and sensor means configured to detect a relative angular position of said crown with respect to said hub, said actuating means controlling said coupling means on the basis of said relative angular position.
