摘要： 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.

摘要： 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.

摘要： 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 can be selectively coupled based on angular position data between the crown and the hub and/or based on data of torque transmitted between the different elements of the system comprising this pulley.

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

摘要： Accessory drives for an internal combustion engine of a vehicle are disclosed that have a first pulley mounted on the drive shaft, a second pulley mounted on the shaft of an electric machine, a belt cooperating with the first and second pulleys, an adjustable-position pulley, and a tensioner. The tensioner has a first tensioning pulley and a second tensioning pulley and at least one spring that biases the first and second tensioning pulleys into contact with respective branches of the belt. The adjustable-position pulley cooperates with the belt to vary the installation tension thereof and is one of the first and second tensioning pulleys, one of the first and second pulleys, or another pulley in the accessory drive.
