Abstract
In a vehicle wheel hub bearing unit the bearing forms a rotating radial flange (11) adapted for securing to a radial flange (12) of a disc or drum brake member and rotate fixedly therewith. The brake flange (12) is located in the same radial plane as the bearing flange (11) and secured directly to the peripheral portion thereof. Radial bulk of the bearing assembly is reduced and deformation of the bearing races and braking surface is avoided.
Claims11
A vehicle wheel hub bearing unit, comprising:
- a bearing having a rotatable radial bearing flange, said bearing flange defining a generally cylindrical outer rim;
- a brake member having a brake flange, said brake flange defining a generally cylindrical inner edge, and said brake flange being located in substantially the same radial plane as said bearing flange;
- and
- means for securing the inner edge of said brake flange directly to the outer rim of said bearing flange, said means for securing comprised of an end portion extending from at least one of said brake flange and said bearing flange.
