摘要:
A light-weight and sound-damped brake rotor for a vehicle braking system includes a rotor hat and a rotor cheek supported by the rotor hat. The rotor hat includes an axially-protruding central hub and a flange that extends radially from and circumferentially around the central hub. The rotor cheek, which provides at least one braking surface, is formed from two or more separate and distinct pieces which are fixedly secured to the flange of the rotor hat. Located within the rotor cheek underneath the at least one braking surface is a vibration damping element. The brake rotor derives its vibration-deadening and sound-damping effects from the vibration damping element through the occurrence of relative frictional contacting movement.
