Patent ID: 7654365

Claim:
A disc brake assembly for mounting on a vehicle comprising: a hub, said hub comprising a mounting flange and an axially extending outer wall, said hub further comprising a plurality of drive cogs extending radially outward from said axially extending outer wall, each of said plurality of drive cogs having an axial thickness defined by an axially inward facing surface and an axially outward facing surface, each of said drive cogs further comprising a circumferentially forward facing surface and a circumferentially rearward facing surface, said circumferentially forward facing surface and said circumferentially rearward facing surface of adjacent drive cogs of said plurality of drive cogs defining a radial slot therebetween, wherein said circumferentially forward facing surfaces and adjacent circumferentially rearward facing surfaces of said plurality of drive cogs collectively define a plurality of radial slots, said hub further comprising a plurality of axial slots formed in said outer wall intersecting said radial slots, said axial slots having an axial depth greater than said axial thickness of said plurality of drive cogs; a brake rotor, said brake rotor comprising a disc member having an axially outward surface and an axially inward surface, said brake rotor further comprising a plurality of teeth extending radially inward from said disc member, said plurality of teeth sized to correspond to said plurality of radial slots for engaging said plurality of drive cogs, each of said plurality of teeth further comprising an axially inward facing surface and an axially outward facing surface; and an axially outward retainer rigidly attached to said axially outward facing surface of at least one of said plurality of teeth, said axially outward retainer extending in a circumferential direction beyond said at least one of said plurality of teeth to engage said axially outward facing surface of at least one of said plurality of drive cogs, said axially inward facing surface of said brake rotor having no contact with said hub, said brake rotor being retained from moving axially inward beyond a predetermined distance solely by said axially outward retainer, said predetermined distance being independent of the axial thickness of the brake rotor.
