A tensioner for an accessory drive of an internal combustion engine has a belt on a first pulley connected to a drive shaft of the engine and a second pulley connected to an electric machine. The tensioner has a base configured to be fixed to a casing of the electric machine, a first ring rotating with respect to the base about a first axis, a second ring rotating with respect to the first ring about a second axis distinct from the first axis, a first tensioning pulley carried by the first ring and rotating with respect to it about its own axis, a second tensioning pulley carried by the second ring and rotating with respect to it about its own axis and elastic means acting on the first and on the second ring to push the first and the second pulleys into contact with respective spans of the belt.

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.

Accessory transmission for a powertrain group of a vehicle and powertrain group comprising such transmission

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.

Powertrain for a motor vehicle and control method thereof

A toothed belt comprising a body made of elastomeric material, embedded in which is a plurality of longitudinal filiform resistant inserts, and comprising a toothging coated with a coating fabric; on top of the coating fabric a resistant layer is made to adhere, which increases the resistance to wear of the toothed belt and which comprises a fluorine-based plastomer with elastomeric material added, in which the plastomer is present in an amount greater than that of the elastomeric material. Preferably, the plastomer is polytetrafluoroethylene, and the elastomeric material comprises HNBR. Advantageously, the resistant layer has a thickness of between 0.01 and 1.5 mm, and between the coating fabric and the resistant layer is set an adhesive material.
