Abstract
A light-weight, sound-damped, composite brake rotor for a vehicle braking system includes a rotor hat and an annular rotor cheek supported by, and cast around, the rotor hat. The rotor hat includes an axially-protruding central hub and an integral flange that extends radially from and circumferentially around the central hub. The rotor cheek includes a top ledge and a bottom ledge that overly a top annular surface and a bottom annular surface, respectively, of the integral flange. An annular interfacial boundary present between an underside of the top and/or bottom ledges and their respective adjacent annular surfaces of the integral flange includes a vibration damping interface. The brake rotor derives its vibration-deadening and sound-damping effects from the vibration damping interface through the occurrence of relative frictional contacting movement.
