Device for lubricating rear bush in extension housing of automotive transmission

摘要

The oil grooves which are formed in the bore of a hollow rear bushing that is disposed adjacent to the rear end of an extension housing of an automotive transmission are provided in such a pattern that upon rotation of the output shaft or sleeve journalled in the bore, lubricating oil is drawn into the grooves from both the front and rear ends of the bushing. The oil drawn in is distributed over the whole inner surface of the bore and discharged into the space behind the rear bushing. The extension housing is provided with a passageway which interconnects the space behind the rear bushing with the space ahead of the rear bushing.
