A decoupler pulley is provided for automotive belt-driven accessory drives, which utilizes a single torsion coil spring that provides torsional resiliency and overrunning functionality. As the torsion spring expands it increasingly pinches a bushing disposed between a radially expansible hub and pulley to thereby provide proportional damping.

One embodiment is a system comprising an internal combustion engine including an output shaft, a pulley system structured to be driven by the output shaft, a first alternator and a second alternator structured to be driven by the pulley system, and an electromagnetic clutch integrated within one of the pulley system, the first alternator and the second alternator and structured to selectably couple and decouple at least one of the first alternator and the second alternator from the output shaft. The system includes a controller in operative communication with the internal combustion engine system and structured to evaluate power demand and power production capability parameters of the system and to control the electromagnetic clutch to engage or disengage in response to the evaluation.

A hub assembly for a hybrid module having a first and a second connection partner arranged coaxially with one another, the first connection partner has a first bearing portion and the second connection partner has a second bearing portion, and a plurality of connecting elements. The first and the second bearing portion have receiving openings for receiving the connecting elements. The first and the second connection partner are prepositioned with respect to one another via a form-fitting connection such that the receiving openings in the first and the second bearing portion are each oriented in pairs in a positionally correct manner with respect to one another in the circumferential direction about the main axis H.

An armature is configured to come into contact with an actuator due to magnetic attraction force. An outer plate is fixed to an armature, the outer plate being located on an opposite side of the armature from the actuator, the outer plate being configured to rotate together with the armature. An inner hub is located between the armature and the outer plate to be movable in a direction along a rotation axis, the inner hub being fixed to a driven device. A rubber member is disposed between the inner hub and the outer plate to give an urging force to the inner hub and the outer plate in a direction away from each other. This electromagnetic clutch is configured such that the urging force of the rubber member non-linearly increases as the actuator and the armature approach each other due to the magnetic attraction force.

A pickup unit of an agricultural baler that includes a reel with a plurality of tines configured for lifting a crop material from a field, the reel is rotatable in an operating direction and a reverse direction, and a drive system configured for driving the reel. The drive system includes a gearbox configured for receiving motive power from a power take off (PTO) shaft, a drive shaft operably connected to the gearbox, and a first clutch connected to the drive shaft. The first clutch is configured for operably disconnecting motive power to the reel so that the reel is manually rotatable as the PTO shaft remains operably engaged with the gearbox.

A vehicle transmission includes a first rotating element, second rotating element, first retainer ring, and second retainer ring. The first rotating element has an exterior surface that defines a first ring groove. The second rotating element is configured to limit movement of friction plates during clutch engagement. The second rotating element is disposed about the exterior surface and has an interior surface that defines a second ring groove. The first retainer ring is disposed in the first ring groove. The second retainer ring is disposed in the second ring groove and thereby restricts movement of the first retainer ring in a radially outward direction.

A limited slip differential having a differential gearset and a cam-type limited slip mechanism. The differential gearset has a plurality of differential pinions that are journally supported by a cross-shaft. The cross-shaft is supported by a rotatable cross-shaft carrier. The limited slip mechanism includes a clutch pack, a pressure ring, a plurality of first cams, which are coupled to the cross-shaft carrier for rotation therewith, and a plurality of second cams that are coupled to the pressure ring. The first cams cooperate with the second cams to convert rotation of the cross-shaft carrier to translation of the pressure ring to thereby control engagement of the clutch pack.
