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: A selectable one way clutch includes a reverse strut pocket plate having a first plurality of struts or pawls, a reverse notch and forward strut pocket plate having a second plurality of struts or pawls, a selector plate disposed between the plates controlled by a selector plate actuator and a forward notch plate. The reverse notch and forward strut pocket plate includes a plurality of ratchet teeth disposed about its periphery which cooperate with a pin or pushrod of a linear actuator. When the reverse notch plate and forward strut pocket plate is stationary but the one way clutch is still carrying torque, the linear actuator may be actuated to rotate the reverse notch plate and forward strut pocket plate to unlock or release the torque carrying struts which would otherwise remain in their locked torque transmitting positions until all or substantially all torque across the clutch was removed.

Abstract: A clutch housing for an automatic transmission includes an aluminum hub and a drum portion which is laser or friction welded to the hub. Due to the different strength requirements of the hub and drum, the hub is fabricated of 6082-T6 aluminum or a material of similar strength and malleability and is forged or die cast. The hub includes male splines or gear teeth disposed on its periphery. The cylindrical drum is fabricated of 7075-T6 aluminum or a material of similar or greater strength and similar malleability and is roller died or stamped and includes female splines or gear teeth on its inner surface as well as a plurality of radially oriented lubrication openings or slots which facilitate flow of lubricating fluid from the interior to the exterior of the cylindrical drum.

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.

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 torque transmitting mechanism includes a drum attached to one of a first member and a second member, and a shell attached to another of the first member and the second member. The drum and the shell are concentrically disposed about a longitudinal axis, with the shell concentrically disposed about the drum. An electric motor includes a stator, and a first rotor rotatable about the longitudinal axis relative to the stator. A band is coupled to the shell, wrapped around the drum between four and twelve complete revolutions, and includes a first end attached to the first rotor for rotation with the first rotor. The band includes a second end attached to a reaction member. Rotation of the first rotor tightens the band against the drum to bias the drum against the shell, to transmit torque between the first member and the second member.
