Transmission mainshaft thrust washer and retainer ring combination

U.S. Patent Number: 5383543

Abstract: A thrust washer and retainer ring combination is provided for a vehicular transmission (100) of the type having adjacent mainshaft gears (12) and (18) floating about a mainshaft (2) that have respective flanges (40) and (42) extending radially inwardly theretowards. A thrust washer (32) is disposed in a groove (38) between flanges (40) and (42) and a pair of retainer rings (28) and (30) are respectively disposed in grooves (34) and (36) adjacent a side of flanges (40) and (42) facing away from each other to prevent gears (12) and (18) from moving axially away from each other. Retainer rings (28) and (30) have an axial width "X" that is greater than the axial width "Y" of thrust washer (32) such that thrust washer (32) cannot be inadvertently received into retainer ring grooves (34) and (36) and the radial height of thrust washer (32) is preferably high enough to prevent it from being received into retainer ring grooves (34) and (36).
