One exemplary embodiment may include a product including a first brake rotor cheek having a first body and at least a first outer surface. A first hardened region may extend from the first outer surface towards the center of the body. In one embodiment, the first hardened region may include a nitro-carburized ferrous metal.

One embodiment of the invention may include a product including a body portion including a first face and a frictional damping insert overlying the first face of the body portion. The body portion may include a second face overlying the insert. The insert may have a throughhole and a portion of the body portion may extend from the first face through the throughhole and the insert to the second face of the body portion.
摘要:
An assembly of like two rib cores enclosing a splitter core are used to carry two or four sound damping inserts for sand mold casting of a pair of vented and damped brake rotors. Sand mold bodies are configured to define outboard surfaces of hub and rotor surfaces of the cast brake rotors. The three-piece core assembly is shaped to define the complex inner surfaces in casting of vented rotor bodies carrying one or two annular sound damping inserts.

A multi-piece sound dampened brake rotor comprises a relatively light weight hub with a hub flange and a heavier rotor body with a sound damping insert and a rotor body flange. The hub and rotor body are attached at their flanges. The flanges may be mechanically attached such as with bolts. Or the hub and rotor may be attached by casting the hub of a lower melting metal alloy against the rotor body and rotor body flange. The rotor body may have vanes for air cooling and a sound damping insert may be incased in either or both body portions sandwiching the vanes.

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.
摘要:
A component with a first number of natural modes of vibration. An insert may be coupled to the component. The insert may have a second number of natural modes of vibration which is a different number than the first number of natural modes of vibration of the component. The insert helps damp vibrations in the component when the component is vibrated.

An exemplary embodiment includes an automotive brake component, such as a brake drum or a brake rotor, and an inlay coupled to the automotive brake component. The inlay constituting at least a portion of a braking surface that is acted upon during a braking event. The inlay damping vibrations in the automotive brake component when the component is vibrated.
