Patent ID: 7568560

Claim:
A disc brake rotor ring for a disc brake rotor assembly, comprising: a first side including an inner perimeter and an outer perimeter, a first annular braking surface and a plurality of first integral, spaced mounting portions positioned along and extending inwardly from the inner perimeter for affixing a corresponding radially extending flange portion of a disc brake rotor hat extending out from one side of said disc brake rotor ring; a second side parallel to and spaced apart from the first side thereby jointly defining a plurality of vents there-between, the second side including an inner perimeter and an outer perimeter, a second annular braking surface having a plurality of second integral, spaced mounting portions positioned on and extending inwardly from the inner perimeter of the second side for affixing a corresponding radially extending flange portion of said disc brake rotor hat, said brake rotor hat having a circular wall partially closed at one end and an annular flange surrounding the circular wall between a fully open end of said brake rotor hat and the partially closed end, said annular flange having an outer face side on the same side as the fully open end and an inner face side opposite the outer face side; said disc brake rotor hat being mounted directly on both of said first and second side spaced mounting portions with said mounting portions from said first and second sides alternating in being connected to the inner face side of said flange portion of said disc brake rotor hat, said inner face side being substantially parallel to the first and second sides of said disc brake rotor ring; and a plurality of threaded fasteners attaching said flange of the hat to the first and second mounting portions with said circular wall of said hat passing through the inner perimeters of said first and second sides; wherein either the first side or the second side may be used as an outboard side when the disc brake rotor assembly is mounted on a wheel hub of a vehicle.
