摘要： A filtering pulley for an accessory drive of an internal combustion engine, having a hub suitable for connection to an engine accessory, an annular crown provided with a profile configured to cooperate with a drive belt, a coil spring able to transmit torque between the crown and the hub, a first carrier constrained to a first end of the spring and a second carrier constrained to a second end of the spring. The annular crown is externally coaxial to the hub and supported in a rotationally free manner on the hub, and each of the carriers is rotationally coupled to both the hub and the crown with a limited possibility of relative rotation with respect to each of them.

摘要： 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.

摘要： Accessory transmission for an engine of a motor vehicle has a first pulley adapted to be connected to a crankshaft of the engine, a second pulley adapted to be connected to a shaft of an electric machine through a one-way clutch, and a belt connecting the first and the second pulley to one another in order to rotate in one and the same rotation direction (R). The one-way clutch is configured so as to couple the second pulley to the shaft of the electric machine when the electric machine drives the second pulley in the rotation direction, and to decouple the second pulley from the shaft of the electric machine when the second pulley tends to overrun the electric machine in the rotation direction.

摘要： 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 are selectively geared between them to selectively connect the crown to the hub.

摘要： 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.

摘要： A transmission belt has a body of a first elastomeric material, a plurality of cords, and a plurality of V-shaped ribs. The V-shaped ribs are arranged side by side and alternate with V-shaped grooves. The V-shaped ribs extend along the transversal axis of the belt. The belt has a first toothing and a second toothing formed by a plurality of teeth that extend obliquely to the transversal axis of the belt, thereby forming therewith respective helix (alpha, beta) angles different from 0°. Power transmission systems that include such a transmission belt are disclosed.

摘要： A transmission module for a hybrid drive vehicle adapted to be interposed between an internal combustion engine and a vehicle transmission has a tray-like support structure defining a housing for a decoupling clutch and adapted to be fixed to the internal combustion engine. A module drive is carried by the support structure and has a first transmission member adapted to be connected to the decoupling clutch by means of a torsional vibration damper and has a second transmission member adapted to be connected to an electric machine. The torsional vibration damper has an actuator defining a centering with respect to the crankshaft and to a transmission torque converter and has a seat for a support bearing with respect to the support structure.
