Various embodiments may include a clutch assembly comprising: a first coupling and a second coupling; and a vibration damper with a spring. The first coupling includes a crankshaft connection and a coupling-in element which can be connected to one another in a controlled manner. The second coupling has an output connection and an intermediate element which can be connected to one another in a controlled manner. The spring connects the intermediate element and the coupling-in element to one another.

Disclosed is a plastic composite including a magnetic alloy material in an amount of about 20% by volume or greater on the basis of the total volume of the plastic composite. Accordingly, weight of the clutch may be reduced by about 0.4 kg and weight of the pulley can be reduced by about 0.4 kg with the result that overall weight may be reduced by about 0.8 kg.

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 clutch carrier assembly for a transmission is disclosed that comprises a clutch carrier and a ring gear carrier. The clutch carrier includes a plurality of tabs and the ring gear carrier includes a plurality of openings defined in, and extending through, an outer surface. The ring gear carrier is disposed within the clutch carrier. Each of the tabs is received within a corresponding one of the openings such that the ring gear carrier and the clutch carrier are held together.

A lockup clutch for a torque converter is provided. The lockup clutch includes a piston including a first wedge surface and a support supporting the piston. The piston is axially slidable along the support in a first axial direction to cause engagement of the lockup clutch. The lockup clutch also includes a wedge including a second wedge surface. The wedge is axially movable along the support. The first wedge surface is arranged and configured with respect to the second wedge surface such that contact between the first wedge surface and the second wedge surface limits axial movement of the piston in a second axial direction opposite the first axial direction. A torque converter and a method of forming a lockup clutch are also provided.

A power transmission device in an automatic transmission includes a friction tightening element (a second brake) having a drum member, and a transmission path constituent member (a third ring gear) coupled to the drum member via a coupling part extending circumferentially along the drum member, the drum member having low-rigidity parts (long holes) provided at a plurality of circumferential positions on the drum member in at least one of portions radially outside and inside the coupling part.

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.

In an aspect, an automotive air conditioning assembly comprising a scroll compressor and a wrap spring clutch. The wrap spring clutch enables the use of a comparatively smaller pulley (a diameter of at most 85 mm) which comparatively increases the compressor speed and hence cooling capacity at a given engine speed. The clutch requires low power (e.g. less than 5 Watts) for continuous operation.
