Abstract: A pulley for a continuously variable transmission is provided with a fixed half-pulley fitted on a supporting shaft and a mobile half-pulley, which is able to slide towards the fixed half-pulley under the thrust of a spring, so as to define a V-shaped race of variable amplitude. The pulley is further provided with a device for compensating the axial thrust, said device being constituted by a cam and a cam follower, which are coupled in contact with one another to impart an additional axial thrust on the mobile half-pulley in response to a torque acting on the pulley. The cam is defined by a tubular body made of plastic material co-moulded on the supporting shaft, whilst the cam follower is made of a single piece with the mobile half-pulley.

Abstract: 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.

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: 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 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.
