Ported wheel hub assembly and the tire inflation system made therewith

A wheel hub assembly, comprising:

• a non-rotating outer bearing flange extending axially between an inboard end of the outer bearing flange and an outboard end of the outer bearing flange;
• an inner bearing flange disposed at least partially concentrically within said outer bearing flange, the inner bearing flange extending axially between an inboard end of the inner bearing flange and an outboard end of the inner bearing flange;
• at least one rolling element disposed radially between said outer bearing flange and said inner bearing flange;
• a fluid port disposed in said outer bearing flange;
• a first conduit disposed through said outer bearing flange in fluid communication with said fluid port and extending axially from the fluid port toward the inboard end of the outer bearing flange to an axial position that is axially closer to the inboard end of the outer bearing flange than any of the at least one rolling elements;
• a second conduit disposed through said inner bearing flange, wherein said second conduit is in fluid communication with said first conduit and extends axially toward the outboard end of the inner bearing flange;
• and
• a rotating spindle disposed at least partially through said inner bearing flange, wherein said spindle is coupled for rotation with said inner bearing flange about an axis of rotation of the inner bearing flange and spindle coupled thereto.
