Abstract: A filtering pulley having a hub adapted to be fixed to a rotating shaft, a pulley ring mounted coaxial and rotationally free on said hub, and at least one elastic assembly interposed between the hub and the pulley ring and a damper for damping the relative oscillations between the hub and the pulley ring is disclosed. The damper has a first damping level for relative rotations between the hub and the pulley ring which are smaller than a predetermined angle and a second damping level, which is greater than the first level, for relative rotations between the hub and the pulley ring which are larger than the predetermined angle.

Abstract: A filtering pulley for an accessory transmission of an internal combustion engine that has a hub, a crown, a filtering unit for transmitting the torque interposed between the hub and the crown, a torsion spring, a carrier, and a torque limiting joint. The torque limiting joint has an open-loop strip spring and is configured to slide with respect to said surface when the torque transmitted between the crown and the hub reaches a predetermined level.

Abstract: A filtering pulley having a hub adapted to be fixed to a rotating shaft, a pulley ring mounted coaxial and rotationally free on the hub, and a plurality of elastic assemblies arranged circumferentially with respect to the hub and the pulley ring and each interposed between a pair of first elements integral with the hub and between a pair of second elements integral with the pulley ring is disclosed. Each elastic element forms with the first elements and with the second elements respective angular clearances, and the pulley ring and the hub have a free angle of relative rotation equal to the sum of the above-mentioned angular clearances.

Abstract: The dual mass flywheel comprises a spring assembly (4; 104; 112; 128; 129), if necessary, with two stages of which one can include a spiral spring. Furthermore, the dual mass flywheel comprises a friction damping system (111) that applies torque independently of the rotational speed of the flywheel.

Abstract: 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.

Abstract: A tensioner for a start-stop accessory drive comprises a movable support, a pulley carried by the support to contact a belt of the drive, a spring to load the support so as to tension the belt, and an actuator controlled and movable to push said pulley against the belt in one direction by means of a load in parallel and additional with respect to that of the spring and an irreversible device which enables the action of the actuator and prevents a displacement of said support in response to the loads of the belt.
