Lubricated bearing for automatic transmissions

摘要

Increased resistance to excessive wear rate is provided in certain automobile automatic transmissions by providing a combination of radial-bushing and thrust-washer at a certain position on the oil pump stator where the customarily manufactured transmission is provided only with a thrust-washer. The combination of radial-bushing and thrust-washer provides bearing surfaces for the direct clutch drum to revolve against in both the lateral and radial directions.
