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 can be selectively coupled based on angular position data between the crown and the hub and/or based on data of torque transmitted between the different elements of the system comprising this pulley.

Filtering pulley, system comprising such pulley and related control method

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.

Filtering pulley

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.

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.

A pulley unit has a hub configured to be connected to a crankshaft, a pulley coaxial to the hub and supported in a rotationally free manner with respect thereto, a clutch interposed between the hub and the pulley, and an actuator for controlling the clutch, The clutch has an inner disc rotationally coupled to the hub and an engagement portion housed inside the pulley, a mobile member axially movable between an engagement position in which the mobile member rotationally couples the pulley to the engagement portion of the inner disc and a disengagement position in which the pulley is rotationally free with respect to the inner disc, and an elastic element acting on the mobile member to push it towards the engagement position.

Pulley for a motor vehicle engine

A tensioner that has a base adapted to be secured to an engine, and at least one arm hinged to a pin fixed to the base and bearing a pulley adapted to cooperate with a belt of a transmission of the engine, and elastic means for pushing the at least one arm in a direction so as to keep the pulley against the belt. The tensioner has sensor means for acquiring in real time a plurality of data relating to the tensioner to estimate the state of efficiency of the same.

Sensorized tensioner

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.

Filtering pulley for a belt drive

A tensioner for a start-stop accessory drive comprises a movable support, a pulley carried by the support to contact a belt of the drive, a spring to load the support so as to tension the belt, and an actuator controlled and movable to push said pulley against the belt in one direction by means of a load in parallel and additional with respect to that of the spring and an irreversible device which enables the action of the actuator and prevents a displacement of said support in response to the loads of the belt.

Controlled tensioner for an accessory drive and accessory drive comprising said tensioner

A tensioner () for a belt drive, comprises a base () defining an axis (A), a mobile eccentric element () hinged about axis (A) and loaded by a spring (), a pulley () idly connected to the mobile element (). Specifically, the pulley () defines a single body with the external ring of a rolling bearing () mounted on the mobile element () and the spring () is helical and presents a square or rectangular cross section.

Pulley tensioner for an oil wet belt drive

Actuator adapted to cooperate with a drive of an endothermic engine including power source and a releasable accessory, the actuator including a box-shaped casing, a motorized eccentric group housed inside the casing and including a reduction gearing, an arm cooperating with the eccentric group and supporting a friction wheel adapted to cooperate with the accessory and with the power source, the arm being mobile between an engaged position and a disengaged position of the accessory.
