ELECTRO CERAMIC COATED ALUMINUM TRANSMISSION COMPONENTS

摘要

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.

主权项

1. A component for a friction clutch pack assembly comprising, in combination,
a circular plate having a center opening, first and second side surfaces and inner and outer edges, one of said inner and outer edges having a plurality of radially extending splines, and said circular plate fabricated of aluminum and having a electro ceramic coating on at least said first and said second side surfaces.
