Abstract: A motor vehicle transmission assembly is provided that includes a dampening component configured to reduce at least one of noise and vibration within the transmission assembly. In some versions, the dampening component is disposed between first and second transmission components, and the dampening component may be fixed to and/or abutting one of the transmission components. The dampening component may comprise a dampening layer disposed between a pair of outer layers. In some versions, the dampening component has a metallic portion and a non-metallic portion.

Abstract: A torque transmitting device for an automotive transmission includes a clutch housing with a plurality of internal splines, a clutch hub with a plurality of external splines extending radially outwardly from the clutch hub, a plurality of friction plates with internal teeth and a first and a second surface. The first and second surface having a friction material disposed thereon and at least one of the internal teeth has an aperture and the plurality of internal teeth intermesh with the plurality of external splines on the outer surface of the clutch hub, a plurality of reaction plates having a plurality of external teeth and a first and a second surface. The plurality of external teeth intermesh with the plurality of internal splines in the clutch housing, and a spacer member disposed in the aperture separates a first of the friction plates from a second of the friction plates.

Abstract: A backing plate configuration and a friction clutch assembly for an automotive transmission are provided. The backing plate configuration includes a main body having a reaction section connected to a perpendicularly disposed strength section. The thickness of the strength section may be less than or equal to the thickness of the reaction section. The friction clutch assembly includes interleaved first and second clutch plates. The main body (of the backing plate) is disposed adjacent to an end second clutch plate. The main body is piloted by and/or splined to the same transmission member as the end second clutch plate. In an engaged position, the end second clutch plate is compressed directly against and into contact with the main body. A method of forming the backing plate configuration is included, which includes stamping of the main body.

Abstract: The present invention is directed to apply plates, clutch plates, reaction plates and backing plates utilized of friction clutch packs, brake housings, clutch hubs, clutch housings, accumulators, spline sets, valve bodies and wear surfaces against which bushings, seals, springs and similar components slide and contact which are utilized in motor vehicle automatic transmissions, are fabricated of aluminum and include an electro ceramic coating deposited thereon. Such components exhibit reduced weight relative to similar components fabricated of steel as well as extended service life due to both the hardness and porosity of the ceramic coating.

Abstract: Friction clutch components, such as apply plates, reaction plates and backing plates for motor vehicle automatic transmissions, fabricated according to the present invention, have reduced weight and improved service life. Apply plates and reaction plates are fabricated of aluminum coated with a thin layer of thermally sprayed steel or ferrous material. Backing plates are fabricated of powdered metal aluminum, stamped and machined aluminum, forged and machined aluminum or extruded aluminum and also coated with a thin layer of thermally sprayed steel or ferrous material. The thermally sprayed steel material may be a low carbon steel such as SAE 1008 or 1010 or a similar alloy. The plates are then finished by belt sanding, brushing or a similar surface finishing technique.
