Patent number: 12379018Abstract: 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.Type: GrantFiled: April 28, 2021Date of Patent: August 5, 2025Assignee: MUVIQ S.R.L.Inventors: Gianluca Cariccia, Andrea Guala, Federico Domenico Licata, Marco Cipelli, Markus Armbrust, Gregorio Luciani

Publication number: 20250215958Abstract: A high-offset belt tensioner has a base having a pivot tube that defines a first axis of rotation, an arm having a pivot tube-receiving body rotatably seated over the pivot tube and having a pulley pivot tube that defines a second axis of rotation. A torsion spring is seated around an exterior surface of the pivot tube-receiving body with a first spring end attached to the base and a second spring end oriented and seated in the pulley pivot tube. A pulley is seated on the pulley pivot tube and rotatable thereabout. A dust cover is seated on the pulley pivot tube juxtaposed to the pulley and a first end of the pivot tube is deformed toward the dust cover to retain the pulley without the use of a pulley bolt.Type: ApplicationFiled: December 26, 2024Publication date: July 3, 2025Applicant: MUVIQ S.r.l.Inventor: Anthony E. Lannutti

Patent number: 12331822Abstract: Filtering pulleys for an accessory transmission of an internal combustion engine have a hub, an annular crown provided with a profile configured to cooperate with a transmission belt positioned externally coaxial around an axis (A) to the hub and supported in rotationally free motion on the hub itself, and a filtering unit for transmitting the torque interposed between the hub and the annular crown. The filtering unit has a torsion spring, a carrier, and a torque limiting joint cooperating with each other to transmit a torque between the hub and the crown. The filtering pulleys can include a damping means carried by a member that is integral with one of the hub and crown and configured to provide variable damping according to the torque.Type: GrantFiled: July 21, 2022Date of Patent: June 17, 2025Assignee: MUVIQ S.R.L.Inventors: Gianluca Cariccia, Andrea Guala, Gilberto Delle Rose

Patent number: 12297897Abstract: 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.Type: GrantFiled: December 10, 2021Date of Patent: May 13, 2025Assignee: MUVIQ S.R.L.Inventors: Gianluca Cariccia, Miriam Nardone, Andrea Guala, Gilberto Delle Rose, Federico Licata

Patent number: 12292112Abstract: High-offset belt tensioners have a support base with a pivot tube and an arm coupled thereto rotation about a pivot axis. A flat wire torsion spring has an inner spring hook attached to the pivot tube and an outer spring hook attached to a first end of the arm at a position that counterbalances a hub load force. The torsion spring applies a spring force to the arm in a direction that moves with the arm throughout its entire sweep in a belt engaging direction. A first plane of the hub load force is axially offset from a second plane of the spring force, a fulcrum is defined between first and second ends of the arm, and a first lineal axial distance from the fulcrum to the first plane is greater than or equal to a second lineal axial distance from the fulcrum to the second plane.Type: GrantFiled: February 25, 2022Date of Patent: May 6, 2025Assignee: MUVIQ S.R.L.Inventor: Anthony E. Lannutti

Patent number: 12276328Abstract: Filtering pullies with a hub adapted to be fixed to a rotating shaft, a crown mounted coaxially and rotationally free on the hub, at least one elastic group arranged circumferentially with respect to the hub and 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 are disclosed. The pulley has a dust protection system configured to isolate the at least one elastic group with respect to the external environment and to provide an axial force generating a damping to the movement between the hub and the crown.Type: GrantFiled: May 17, 2022Date of Patent: April 15, 2025Assignee: MUVIQ S.R.L.Inventors: Gianluca Cariccia, Andrea Guala, Stefano Amadio, Jacopo Spinelli

Patent number: 12270470Abstract: A tensioner for an accessory drive of an internal combustion engine has a belt on a first pulley connected to a drive shaft of the engine and a second pulley connected to an electric machine. The tensioner has a base configured to be fixed to a casing of the electric machine, a first ring rotating with respect to the base about a first axis, a second ring rotating with respect to the first ring about a second axis distinct from the first axis, a first tensioning pulley carried by the first ring and rotating with respect to it about its own axis, a second tensioning pulley carried by the second ring and rotating with respect to it about its own axis and elastic means acting on the first and on the second ring to push the first and the second pulleys into contact with respective spans of the belt.Type: GrantFiled: July 1, 2021Date of Patent: April 8, 2025Assignee: MUVIQ S.R.L.Inventors: Mario Pennazza, Ettore Ramin
