Abstract: 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.

Abstract: A powertrain has an internal combustion engine provided with an accessory transmission that includes a first pulley connected to a crankshaft of the engine, a second pulley connected to a shaft of an electric machine, and a belt connecting the first and the second pulleys to each other to rotate in the same direction of rotation (R). The electric machine is operated to supply an active torque to the second pulley during start-up of the internal combustion engine by means of a starter motor.

Abstract: 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.

Abstract: 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.

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.
