Abstract: 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.

Abstract: 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.

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: 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.

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.
