Abstract
A filtering pulley has a hub configured to be fixed to a shaft for rotation thereabout, a crown mounted coaxial and rotationally free on the hub, and a plurality of elastic groups arranged circumferentially with respect to the hub and to 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. The first elements have at least two spokes, carried by an actuator that is made of two portions that are selectively geared between them to selectively connect the crown to the hub.
Claims16
A filtering pulley comprising;
- a hub configured to be fixed to a shaft rotating around an axis (A),
- a crown mounted coaxial and rotationally free on said hub,
- a plurality of elastic groups arranged circumferentially with respect to said hub and to said crown and interposed, each, between a pair of first elements integral with said hub and between a pair of second elements integral with said crown, said first elements comprising at least two spokes, carried by an actuator,
- characterized in that said actuator comprises a coupling portion carried slidingly but rotationally fixed with respect to said axis (A) by said hub and an actuation portion defining said spokes and rotationally free but fixed to translation with respect to said axis (A) by said crown, said coupling and actuation portions being configured to define a first configuration in which they cooperate so that said crown is operatively connected to said hub and a second configuration in which they are operatively separated so that said crown is operatively disconnected from said hub.
