Abstract: A transmission belt is described which comprises a body made of a first elastomeric material, a plurality of teeth and a plurality of longitudinal cords buried in the body of the belt and a back. The belt has a working surface on said teeth and the working surface is at least partially covered by a covering made of a plastic and/or metal material. Defining the area comprised between the plane defined by the neutral axis of the cords, the working surface and the median transverse planes of two adjacent teeth as the unitary longitudinal section, the covering preferably occupies at least 25% of the unitary longitudinal section.

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: 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 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.
