Abstract:
1. A brake hub assembly comprising; a hub defining a central axis extending axially and including a body and an annulet, said body being of cylindrical shape having a predefined circumference and presenting a radially extending inner face and a radially extending outer face and an axially extending circumferential face extending between said inner face and said outer face, said annulet extending radially from said circumferential face of said body, a plurality of guide pins extending axially from said annulet, at least one disc disposed about said body and having at least two friction surfaces defining a plurality of guide pin receiving bores spaced radially from said central axis, said guide pins being slidably disposed in said guide pin receiving bores for coupling said hub and said disc to limit rotational movement between said hub and said disc while allowing axial movement of said disc relative to said hub, a spring including a band disposed circumferentially about said circumferential face of said body of said hub, and characterized by said circumferential face of said hub defining a circumferential groove extending circumferentially about said circumferential face and a plurality of axial position retention tabs circumferentially spaced and extending radially inwardly from said band and engaging said circumferential groove of said body of said hub for preventing axial movement between said spring and said hub along said central axis.
