    Abstract: 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.

    Abstract: Power transmission belts described herein have a nitrile group-containing copolymer rubber that has an acrylonitrile unit, a monomer unit of α,β-ethylenically unsaturated nitrile monomer other than acrylonitrile, and a conjugated diene monomer unit. The nitrile group-containing copolymer rubber has an iodine value of 120 or less a total of the acrylonitrile unit and the monomer unit of α,β-ethylenically unsaturated nitrile monomer other than acrylonitrile is 1 to 50% by weight in the total monomer unit, and a weight ratio of the acrylonitrile unit and the monomer unit of α,β-ethylenically unsaturated nitrile monomer other than acrylonitrile is 10:90 to 90:10.

    Abstract: A transmission module for a hybrid drive vehicle configured to be interposed between an internal combustion engine and a transmission of the vehicle has a tray-like support structure configured to be secured to the engine and defines a housing for a clutch to be interposed between a crankshaft of the internal combustion engine and the module. An actuator controls the clutch. The actuator includes an annular chamber provided in the support structure and opens toward the housing, and an annular piston housed in the annular chamber is axially sliding but angularly fixed. A thrust member is coupled in a rotationally free manner to the annular piston, coaxial thereto and operable to cooperate with a control member of the clutch under the thrust of the piston.

    Abstract: A tensioner that has a base adapted to be secured to an engine, and at least one arm hinged to a pin fixed to the base and bearing a pulley adapted to cooperate with a belt of a transmission of the engine, and elastic means for pushing the at least one arm in a direction so as to keep the pulley against the belt. The tensioner has sensor means for acquiring in real time a plurality of data relating to the tensioner to estimate the state of efficiency of the same.

    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.
