Abstract
An apparatus for reducing unwanted brake noise has a ring damper affixed around a periphery of a brake rotor in a disk brake system in a manner that permits relative motion and slippage between the ring damper and the rotor when the rotor vibrates during braking. In a preferred embodiment, the ring damper is disposed in a groove formed in the periphery of the disk and is pre-loaded against the rotor both radially and transversely. The ring damper is held in place by the groove itself and by the interference pre-load or pre-tension between the ring damper and the disk brake rotor.
Claims30
A disk brake rotor having a ring damper affixed to a periphery of the rotor, said ring damper being transversely pre-loaded against said rotor such that said ring damper moves and slips relative to said rotor providing damping of said rotor when the rotor vibrates during braking to damp brake noise.
A ventilated disk brake rotor having an inner disk, and outer disk, and vanes extending therebetween, the inner and outer disk defining a groove therebetween in which a ring damper is disposed, the ring damper comprising first and second opposed rings and a wave-shaped ring sandwiched therebetween, the first and second opposed rings and wave-shaped ring pre-loaded against each other and transversely against the rotor by elastic deformation of the wave-shaped ring.
