Thu, 03 Nov 2016 08:00:00 EDTA stator for a torque converter includes a body portion with a first frusto-conical surface, a flange including a second frusto-conical surface, a stator clutch including the first and second frusto-conical surfaces, and at least one clutch plate disposed therebetween. In some example embodiments, the at least one clutch plate comprises a pair of frusto-conical surfaces. In an example embodiment, at least one of the at least one clutch plate frusto-conical surfaces includes a friction material bonded thereto. In an example embodiment, the body portion or the flange includes a first drive tab and the at least one clutch plate includes a second drive tab drivingly engaged with the first drive tab.
Thu, 03 Nov 2016 08:00:00 EDTA rotation transmission device includes torque cams provided between opposed surfaces of a flange of a control retainer and a flange of a rotary retainer and configured to convert an axial movement of the control retainer to relative rotational motion between the two retainers. All of the torque cams are circumferentially offset from all of the pillars of the control retainer and all of the pillars of the rotary retainer, and a pair of cam grooves forming each torque cam are heat-treated only at their areas that are brought into contact with a ball of the torque cam, to increase the hardness of these areas, thus improving the durability of the retainers.
Thu, 03 Nov 2016 08:00:00 EDTA ball ramp plate assembly includes a first ball ramp plate and a second ball ramp plate coaxially aligned so that first and second ball pockets are opposed with rolling elements disposed in the opposing first and second ball pockets. A plug extends through the first ball ramp plate and the second ball ramp plate and engages both ball ramp plates to maintain the first ball ramp plate and the second ball ramp plate against displacement with respect to each other.
Thu, 03 Nov 2016 08:00:00 EDTA friction disc. The friction disc includes a plate having a forward facing plate surface, a rearward facing plate surface, an inward facing plate surface, and an outward facing plate surface. An inward facing plate surface has a plate lug extending radially inwardly. The friction disc includes a hub having an inward facing hub surface and an outward facing hub surface. The outward facing hub surface has a hub lug extending radially outwardly. The friction disc includes a damping web connecting the plate to the hub to transmit torque between the plate and the hub to rotate the plate and the hub mutually. The damping web includes a resiliently deformable material that limits transmission of shock between the plate and the hub.
Thu, 03 Nov 2016 08:00:00 EDTA torque limiter assembly includes a drive disc, a driven disc, a pressure plate, an offset plate, a bladder, a first clutch lining, and a second clutch lining. At least a portion of the bladder contacts the offset plate. The pressure plate is separated from the offset plate via a plurality of offset members and the first clutch lining is disposed between the drive disc and the driven disc. The second clutch lining is disposed between the drive disc and the pressure plate. The bladder is pressurized to set a threshold torque at which the clutch of the assembly begins to slip. The assembly further includes a central hub. The central hub has bolts which extend radially therefrom and which secure the central hub to a shaft. The bolts are positioned between the pressure plate and the offset plate.
Thu, 03 Nov 2016 08:00:00 EDTA clutch having a clutch housing and a drive sprocket coaxially and rotationally mounted about a drive housing that is coaxially mounted about a shaft portion. The clutch housing has one or more drive sprocket engaging members with a locked and an unlocked position. When locked the drive sprocket engaging members lock the drive sprocket to the drive housing. When unlocked the drive sprocket engaging members permit the drive sprocket to rotate independently from the. A return drive mechanism includes a tether, a tether base and a return spring. The tether has a first end secured to the tether base and a second end secured to the clutch housing. The clutch housing, tether base and return spring are axially aligned and coaxially mounted about the shaft portion to present an overall compact clutch structure to facilitate mounting in confined locations.
