摘要： A damper device includes a first rotor, a second rotor, and an elastic coupling part. The elastic coupling part has a first torsional characteristic, a second torsional characteristic, and a third torsional characteristic. The first torsional characteristic is exerted with a first stiffness in a first actuation range of a torsion angle that ranges differently on the positive side and on the negative side. The second torsional characteristic is exerted with a second stiffness, which is greater in magnitude than the first stiffness, in a second actuation range of the torsion angle that ranges on the positive side of the first actuation range. The third torsional characteristic is exerted with a third stiffness, which is greater in magnitude than the first stiffness and different in magnitude from the second stiffness, in a third actuation range of the torsion angle that ranges on the negative side of the first actuation range.

摘要： A multiple disc clutch includes an axially displaceable outer disc hooked into an outer disc carrier to provide a first friction surface, and an axially displaceable inner disc hooked into an inner disc carrier to provide a second friction surface for a friction pairing with the first friction surface. The outer disc has an outer coupling element for coupling to the outer disc carrier and the inner disc has an inner coupling element for coupling to the inner disc carrier. The outer disc has an outer ring, the outer coupling element extends radially from the outer ring, and the first friction surface is connected to the outer ring by an outer leaf spring element; or the inner disc has an inner ring, the inner coupling element extends radially from the inner ring, and the second friction surface is connected to the inner ring by an inner leaf spring element.

摘要： A clutch includes a hub and a flange located radially inside and outside, respectively, with respect to the clutch rotational axis and associated with hub and flange sides of the clutch. A spring elastically supports the hub and flange sides against each other in the circumferential direction in a torque-transmitting manner. A bearing radially supports the hub and flange sides against one another for rotation around the axis and includes an outer ring supporting the hub and an inner ring supported on a bearing pin associated with the flange side. A friction device connects the hub and flange sides in a friction-locked and torque-transmitting manner in the circumferential direction and includes a friction element and a friction surface which are pretensioned against one another in the axial direction. A tensioning device includes a tensioning element that applies force to, and axially pretensions, the friction device and bearing.

摘要： A pack includes a set of first friction disks interleaved with a set of second friction disks to form a stack. An annular pressure plate has an engagement side disposed against the stack. The engagement side includes an outer circumferential edge, an inner circumferential edge, a flat face extending radially inward from the outer edge, a step axially recessed into the engagement side relative to the face, and a tapered face extending from the step to the inner circumferential edge. The tapered face is disposed against an end one of the first friction disks, and the flat face is radially outboard of the first friction disks.

摘要： A clutch arrangement has a clutch housing and a clutch element carrier, one of which receives at least one clutch element and the other of which is configured as a friction area carrier for a friction area so that, to produce a frictional engagement connection, the clutch element can be brought into operative connection with the friction area or, to cancel the frictional engagement connection, the clutch element can be separated from the friction area. The clutch element has a support for a friction facing, and the clutch element has a holding device radially adjacent to the friction facing for receiving the support of the clutch element. The support has at its side opposite the friction facing a further friction facing acting as seal.

摘要： A clutch device includes an outer disk carrier, outer disks, an inner disk carrier, inner disks, and at least one lug. The outer disk carrier has first axially running grooves, a first edge, and a first edge side. Each of the outer disks has radial projections spaced apart by depressions and projecting into the first axially running grooves. The inner disk carrier has second axially running grooves, a second edge, and a second edge side. Each of the inner disks has radial projections spaced apart by depressions and projecting into the second axially running grooves. The lug is arranged between two grooves of the first axially running grooves and extending axially from the first edge side, or arranged between two grooves of the second axially running grooves and extending axially from the second edge side.

摘要： An assembly comprising a first member, a second member, and a clutch plate. The second member is maintained in a spaced apart relationship from the first member. The clutch plate has radially extending engagement structures and is disposed between the first member and the second member. The clutch plate has a first half and a second half that are slidably rotatable with respect to one another. The first half and the second half of the clutch plate rotate in opposite directions when axial pressure is applied to the first member.

摘要： A snap ring is configured to retain components within a clutch assembly. The snap ring has an annular body defining an opening through a center thereof. The annular main body defines a distal-facing surface and an opposite proximal-facing surface. A number of retention features extend from the distal-facing surface of the annular main body. Each retention feature has an axially-extending body portion a radially-extending engagement portion. The engagement portion is configured to engage a backing plate. A friction clutch assembly including a snap ring pair is also provided, which includes a clutch snap ring disposed adjacent to the snap ring including the retention features.

摘要： A damper device is capable of attenuating fluctuations in torque. The damper device includes a first rotor and a second rotor rotatable relatively to the first rotor. The damper device also includes a plurality of elastic members elastically coupling the first rotor and the second rotor. The second rotor is rotatable relatively to the first rotor while held by the first rotor with use of the plurality of elastic members.
