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: 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 transmission system is provided that has a drive pulley, at least one driven pulley and an oil wet toothed belt. The toothed belt includes a toothing and a back, a first portion, wherein the toothing is coupled to the drive pulley, a second portion wherein the toothing is coupled to at least one driven pulley, a first taut branch which develops towards the driving pulley and a second slack branch which develops towards the driven pulley. The transmission system also includes a fixed containment guide having at least a first wall facing the toothing and/or the back positioned at a distance from the toothed belt between a minimum distance where at rest it is not in contact with the toothed belt and a maximum distance equal to 5% of the length of one between the taut branch and the slack branch.

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.
