Abstract: Components for an automatic motor vehicle transmission including a band brake drum, a clutch housing or hub having a seal surface or a clutch housing or hub utilized in a friction clutch assembly having a spline set. All of these components are fabricated of aluminum and the outer surface of the band brake drum, the housing or hub sealing surface and the area of the spline set includes a thin coating of a thermally sprayed steel material. The thermally sprayed steel material may be a low carbon steel such as SAE 1008 or 1010, a similar alloy, iron or other metal. The resulting components thus exhibit the weight saving of aluminum while providing excellent service life due to the enhanced strength and wear resistance provided by the thermally sprayed steel coating.

Abstract: Friction clutch reaction plate assemblies include two thin reaction plates which are preferably secured together in spaced relation to form a single reaction plate assembly. At least plate includes through openings which improve fluid flow between and around the plates and both plates include projections which align and define the spacing between the plates. The two plates may be secured together by various means such as spot welding, CD welding, laser welding, riveting or an adhesive. The axial space between the splines or teeth which couple the reaction plate to a clutch component (either a hub or a housing) may be reinforced with material to improve surface area contact. The reaction plate assembly has a thickness substantially equal to a conventional reaction plate in order that it may be readily substituted into current friction clutch assemblies.

Abstract: The present invention provides a stamped steel friction clutch hubs or housings for use in automatic motor vehicle transmissions having a sprayed on hard steel or ceramic coating on wear surfaces. The clutch hub or housing is fabricated of steel which is stamped and of unitary construction. The clutch hub or housing is complexly configured and includes a center through opening having an inner surface which is contacted by a pair of resilient, axially spaced apart seals. The housing also includes a larger diameter portion having female splines which engage male splines on the periphery of a portion of the clutch plates. The inner surface which is contacted by the resilient seals includes a thin layer of sprayed steel or ceramic material that is machined after application to a desired diameter and surface finish.

Abstract: A weld includes a first component and a second component. The first component includes a fay surface with one or more grooves. The second component includes a surface that is configured to mate with the fay surface of the first component. The fay surface of the first component and the surface of the second component form a friction weld when the two surfaces are mated together and relative motion between the first component and the second component generates heat through mechanical friction between the two components.
