Abstract: A facing material for a power transmission—absorption assembly is shown and described. In one embodiment, the facing material includes a plurality of first channels having a first, deep depth and a plurality of second channels having a second, shallow depth. One or more of the plurality of second channels may be superimposed or in fluid communication with the first channels to enable fluid to flow across the surface 12c and through the first channel to achieve the desired fluid flow characteristics. The second channels may be defined by a connector that has varying shapes to further facilitate the desired fluid flow characteristics. The material may be used in a power transmission—absorption environment such as on a blocker synchronizer ring, clutch plate or the like.

Abstract: A volute spring that is particularly adapted to be incorporated in a damper assembly to absorb or neutralize the transient torsional spikes normally occurring at the crankshaft of a vehicle. A volute spring having the improved frictional hysteresis characteristic provided by the present invention utilizes the conventional plurality of telescopically adjacent coils, and each coil has oppositely directed surfaces which present opposed surfaces on the telescopically adjacent coils. At least one of the opposed engaging surfaces has a configuration that obviates the formation of a hydrodynamic oil film. One configuration that obviates the formation of a hydrodynamic oil film comprises a plurality of intersecting grooves recessed into at least one surface of the metallic strip from which the volute spring is wound. The intersecting grooves define a plurality of polygonal lands which cumulatively provide at least one of the engaging surfaces on the adjacent coils of the volute spring.

Abstract: A clutch plate member for operating in a fluid medium to transmit torque to a metal mating surface situated on an opposing clutch plate member in a wide range of slip speeds. The clutch plate member is constructed of a friction facing layer consisting of thermoset resin bonded carbon particles bonded to a compliant carrier sheet which is in turn bonded to a metal support plate. The compliant carrier sheet improves the conformability of the friction facing layer to the metal mating surface resulting in a reduction in the maximum operating temperature of the friction facing layer.

Abstract: A double wrap brake band is manufactured from three substantially equal length strips of metal which are bonded together in a "Y" or tuning fork shape. The bonded straps are then formed into a cylindrical shape and friction material is bonded to the inner surfaces. Operating lugs are secured at the outer free end of each strap. In the alternative, the operating lugs can be formed integral with the strap or otherwise secured to the strap either prior to or subsequent to the bonding of the straps. The lugs can be formed integral with their respective strap by deformation of the strap material. The double wrap band can also be manufactured by assembling three pre-shaped hoop members. The hoops are assembled coaxially and have an open face which is angularly displaced from the hoop adjacent thereto. The adjacent hoops are secured by welding or using a tie bar at the adjacent surfaces between the open ends.

Abstract: A friction disc for a clutch or brake is formed from a plurality of arcuate segments. The segments are stamped from a rectangular sheet of pregrooved friction material, interconnected by integral tab and slot structures to form an annulus, and bonded to an annular metal member.

Abstract: A clutch and damper assembly wherein a single plate clutch has torsion springs and deformable resilient members, permitting a wide angle of travel, disposed between the clutch input and output to accommodate engine torsional vibrations imposed on the clutch. The torsion springs permit a predetermined amount of relative angular movement between the clutch input and output at a predetermined rate, and the resilient members become operable after the predetermined motion to permit further relative motion at a higher rate. A friction assembly included within the damper dissipates the periodic energy of the torsional vibrations.

Abstract: Metal fibers of uniform or other predetermined sizes are made by knurling a pattern of ridges and depressions on the surface of a metal workpiece. The fibers are formed by shaving the ridges from the knurled surface. The knurling-shaving process is repeated to make more fibers.
