Patent ID: 7066306

Claim:
A disc brake rotor having a central hub coaxial with and supporting annular rings which form an inboard brake disc and an outboard brake disc for engagement with brake pads, said inboard disc and said outboard disc maintained in a parallel spaced apart configuration by pillars with channels defined between said pillars whereby in use of the rotor, air is drawn in through vent means and then radially outwardly through said channels as the rotor turns, said pillars arranged in repeating clusters of six; said pillars in cross section including radially aligned inner and outer pillars with pairs of intermediate pillars positioned radially between said inner and outer pillars; one pair of said intermediate pillars on each side of a radially aligned central axis defined by said radially aligned inner and outer pillars; said pairs of intermediate pillars positioned to support said inboard and outboard brake discs against mechanical distortion from application of said brake pads during heavy braking; each pair of said pairs of radially aligned intermediate pillars defining a channel between the pillars comprising said pair; said channel offset from a radially aligned direction.
