Bearing retainer ring

A wheel hub assembly for a non-driven axle comprising:

• a hub including a generally cylindrical main body and a central bore extending therethrough, a portion of said central bore defining a bearing seat, said hub also including a wheel mounting flange extending radially outward from said main body, said wheel mounting flange having wheel mounting bores defined therein and having opposing faces;
• wheel mounting studs disposed within said wheel mounting bores having enlarged heads on one opposing face of said wheel mounting flange and a threaded shaft extending from the other opposing face;
• a bearing having an inner race and an outer race, said bearing being positioned within said central bore in engagement with said bearing seat;
• and
• a bearing retainer ring including a mounting portion having at least one ring mounting bore corresponding to one of said wheel mounting bores, said bearing retainer ring being secured to said wheel mounting flange by at least one of said wheel mounting studs extended through both said ring mounting bore and said corresponding wheel mounting bore with said bearing retainer ring being disposed between said enlarged head of said at least one of said wheel mounting studs and said wheel mounting flange, said bearing retainer ring also having a retaining portion directly engaging said bearing, said retaining portion acting upon said bearing and providing a preload onto said bearing to assist in retaining said bearing in said bearing seat whereby said bearing is axially retained in said wheel hub assembly by application of a positive retention load solely by the addition of said bearing retainer ring to said wheel hub.
