International Classification:

F16D 314

US Classification:

192 7017, 1922133, 192214

Abstract:

Disclosed herein is a friction torque device with an improved damper for attenuating torsional vibrations. The improved damper provides the desired axial load for damping while reducing the weight, cost, complexity and size of a driven disk for a friction torque device. A friction torque device comprises a driving member having of rotation, a cover coupled to the driving member for rotation therewith, a pressure plate coupled to the cover for rotation therewith and a driven disk coupled to an axially extending driven shaft for rotation therewith. The driven disk is interposed between the driving member and the pressure plate, the driven disk includes a rotatable disk assembly and a hub assembly. The driven disk comprises at least one reinforcing plate having a plurality of undulations disposed therein for providing a load between the disk assembly and hub assembly. The reinforcing plate may be coupled to the disk assembly, the hub assembly or the plate may not be attached to another component.

US Classification:

192 7017, 192212, 464 64, 464 68

Abstract:

A driven disk in a clutch comprises a hub having a flange extending radially therefrom and having a spring cover affixed thereto. The spring cover defines at least one spring cavity therein and has two ends. Opposing first portions of the two ends define a first cavity length, and second opposing portions of the two ends define a second cavity length. A first spring is retained within the spring cavity wherein the first spring bears against the first end portions defining the first length. A second spring is also retained within the spring cavity wherein the second spring bears against the second end portions defining the second length.

Eaton Corporation - Cleveland OH

International Classification:

F16D 13/68

US Classification:

192 5561, 192 7017, 1922141

Abstract:

A driven disc is provided that includes a hub assembly having an axis of rotation and a hub having at least one of a first radially extending projection and a first recess. The driven disc also includes a disc assembly having a disc plate rotatable relative to the hub and a wave washer positioned over the hub and between the hub assembly and the disc assembly. The wave washer includes at least one of a second recess and a second radially extending projection adapted to receive or to be received in the first radially extending projection or the first recess, respectively, to position the wave washer during assembly of the driven disc.

International Classification:

F16D 13/64

US Classification:

192107C, 192 526

Abstract:

A clutch disc assembly for a friction torque device has a clutch damper assembly which includes a hub defining an axis of rotation and a concentric steel disc. The damper assembly includes a plurality of cushion elements fixed to the steel disc. First and second friction rings are disposed on opposite sides of the cushion elements and are rotatively fixed to the steel disc. First and second friction discs have an equal number of keyhole slots defining an equal number of arms. A friction pad is fixed to each arm, with friction pads on the first friction disc being in substantial alignment with the friction pads on the second friction disc.

US Classification:

192105CP, 192 7017, 192213

Abstract:

An embodiment provides a friction clutch apparatus that includes a disk assembly disk. The disk assembly has a disk portion selectively coupled to a first member, and a hub portion selectively coupled to a second member. The hub portion is generally axially aligned with the disk portion. The disk portion is rotatable relative to the hub portion. The disk assembly selectively transmits a torque between the first member and the second member. The disk assembly also includes an energy storage member selectively damping the relative rotation between the disk portion and the hub portion. The damping includes relative rotation between the disk portion and the hub portion. The energy storage member is preloaded, thereby requiring a preselected amount of torque to be applied by one of the disk portion and the hub portion to the other of the disk portion and the hub portion prior to the relative rotation.
