Patent number: 11815172Abstract: Filtering pulleys have a hub adapted to be fixed to a rotating shaft, a ring assembled coaxial and rotationally free on the hub, and an elastic assembly arranged circumferentially with respect to the hub and the ring and interposed between a pair of first elements integral with the hub and between a pair of second elements integral with the ring. The elastic assembly includes an elastic element having a progressive rigidity increasing starting from a predetermined threshold value of the angle of relative rotation between the hub and the ring.Type: GrantFiled: February 23, 2018Date of Patent: November 14, 2023Assignee: Dayco Europe S.R.L.Inventors: Gianluca Cariccia, Andrea Guala, Ettore Gaude, Gregorio Luciani

Patent number: 11585390Abstract: A filtering pulley assembly for an accessory drive of a vehicle has a hub fixedly attachable to a rotating shaft, a pulley mounted coaxial and freely rotating on said hub, an actuator disc carried by the hub, a plurality of elastic assemblies interposed between the pulley and the actuator disc, and a torque limiting coupling configured to rotationally connect the actuator disc to the hub, when the torque is below a predetermined threshold value, and to decouple the actuator disc from the hub, when the torque is above the threshold value.Type: GrantFiled: May 22, 2018Date of Patent: February 21, 2023Assignee: Dayco Europe S.R.L.Inventors: Gianluca Cariccia, Andrea Guala, Gregorio Luciani, Ettore Gaude, Stefano Amadio, Daniele Esposto, Markus Armbrust, Marco Cipelli

Patent number: 10781907Abstract: 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.Type: GrantFiled: March 18, 2016Date of Patent: September 22, 2020Assignee: Dayco Europe S.R.L.Inventors: Gianluca Cariccia, Andrea Guala, Ettore Gaude, Gregorio Luciani

Patent number: 10753453Abstract: 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.Type: GrantFiled: March 18, 2016Date of Patent: August 25, 2020Assignee: Dayco Europe S.R.L.Inventors: Gianluca Cariccia, Andrea Guala, Ettore Gaude, Gregorio Luciani
