DETAILED DESCRIPTION
[0017] Fig. 1 shows a portion of a torque converter 10 according to an embodiment of the present invention. Torque converter 10 includes a thrust washer 12 positioned axially between a first rotating component 14 and a second rotating component 16, at least one of which subjects the other component 14, 16 to a thrust. In this embodiment, component 14 is a turbine hub 18 and component 16 is a piston 20. In other embodiments, thrust washer 12 may be positioned between different rotating components of a torque converter. Fluid within torque converter 10 flows along outer surfaces 32 of thrust washer 12 to help prevent wear between components 14, 16.
[0018] Fig. 2 shows thrust washer 12 in accordance with an embodiment of the present invention. Thrust washer 12 is ring shaped and includes a wet friction material layer 22 sandwiched between two phenolic resin layers 24. Phenolic resin layers 24 may be for example Resin Arofene 295-E-50 or MACtac IF-4023A. Wet friction material layer 22 is a porous material including surface pores 26 on opposing outer surfaces 28 thereof before phenolic resin layers 24 are applied to outer surfaces 28. Phenolic resin layers 24 are formed on wet friction material layer 22 such that surface pores 26 are filled by the phenolic resin and outer surfaces 32 of thrust washer 12 have a low coefficient of friction, which provides for smooth interactions between outer surfaces 32 and components 14, 16. Wet friction material layer 22 may be formed of any known wet friction material, for example a fiber matrix impregnated with resin. A plurality of grooves 30 may be formed in the outer surfaces 32, at outer surfaces 34 of phenolic resin layers 24, to provide passages for fluid to flow along outer surfaces 32.
[0019] Fig. 3a schematically shows a method for forming thrust washer 12 in accordance with an embodiment of the present invention. Wet friction material layer 22 is coated with phenolic resin layers 24 on opposite sides thereof. In one preferred embodiment, phenolic resin layers 24 are formed as laminated sheets. Phenolic resin layers 24 are appropriately positioned on outer surfaces 36 of wet friction material layer 22 and layers 22, 24 are placed between two press sections of a hot press 42, which is this embodiment are a lower press plate 38 and an upper press plate 40. A first non-stick layer 44 is provided between the lower phenolic resin layer 24 and lower press plate 38 a second non-stick layer 46 is provided between the upper phenolic resin layer 24 and upper press plate 40 to prevent phenolic resin layers 24 from sticking to press plates 38, 40. Nonstick layers 44, 46 may be formed of for example waxed paper or TEFLON. Press plates 38, 40 are heated to between 350°F and 420°F and a downward force may be applied to upper press plate 40 to heat and cure phenolic resin layers 24, causing phenolic resin layers 24 to plug surface pores 26 of wet friction material 22.
[0020] Fig. 3b schematically shows a method for forming a thrust washer 12a in accordance with an alternative embodiment of the present invention. In this embodiment, thrust washer 12a is formed in the same manner as thrust washer 12, but with wet friction material 22 being split into a first wet friction material layer 22a and a second wet friction material layer 22b that are separated by a metal layer 48. Layers 22a, 22b may be attached to metal layer 48 by adhesive or another connection. As with the embodiment in Fig. 3a, non-stick layers 44, 46 are provided between resin layers 24 and respective press plate 38, 40, which are used to heat and cure phenolic resin layers 24, causing phenolic resin layers 24 to plug surface pores 26 of wet friction material 22.
[0021] In the preceding specification, the invention has been described with reference to specific exemplary embodiments and examples thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative manner rather than a restrictive sense.
