Abstract: A ventilated brake rotor having vents disposed between two discs. The vents are defined by an adjacent pair of vanes distributed around the first disc and disposed below the second disc. Each vane is defined by a camber. The camber, in turn, is parallel to a curve that is defined by two camber lines. The curve is tangent to the leading end of a first camber line and tangent to a trailing end of the second camber line. The first and the second camber lines intersect where the first camber line is defined from a point on the interior radius of one of the two discs that intersects a datum. Moreover, the first camber line extends at a throat angle from the datum.

Abstract: The present invention relates to a rotor assembly. The rotor assembly includes a rotor having rotor holes disposed about an axis. Bushings are disposed within the rotor holes in order to protect the rotor holes from compression impact deformation. Each bushing includes an internal slot that permits the rotor to radially expand and contract due to changes in the temperature of the rotor. A hub having pin holes that align with the rotor holes is held to the rotor by drive pins disposed within the pin holes and the bushings. A bolt is placed into the drive pin and tightened to fix the hub to the rotor in the axial and circumferential directions. Other features are disclosed.
