Abstract: A wheel hub includes an improved structure for mounting at least one accessory thereto, the wheel hub has a hollow cylindrical body having a radially acting coupling arrangement including a plurality of alternating recesses and ridges formed interiorly of the hollow body for complementary engagement with a portion of the accessory for rotation in unison with the wheel hub. An axially acting coupling arrangement is also provided for holding the accessory substantially against axially movement relative to the wheel hub.

Abstract: A wheel hub is disclosed including an improved structure for mounting at least one accessory thereto. This structure includes a radially acting coupling arrangment including an axially outwardly directed rim portion about a periphery of the wheel hub punctuated by a plurality of recesses for receiving complementary projections on the accessory for coupling the wheel hub and accessory for rotation in unison. An axially acting coupling arrangement is also provided on the wheel hub for holding the accessory substantially against axial movement relative to the wheel hub.
