摘要:
A method is disclosed for forming a brake rotor including a desired custom marking having a predetermined size and shape. The method includes applying a chemical treatment to a marking portion of a surface of the rotor. The marking portion has a size and shape corresponding to the predetermined size and shape of the desired custom marking. The chemical treatment is configured to affect, in a predetermined manner, an ability of a stimulus, to which the rotor is to be exposed, to alter properties of the rotor. The method also includes exposing the rotor, having the chemical treatment applied thereto, to the stimulus. The stimulus alters properties of the rotor at the marking portion differently than the stimulus alters properties of the rotor at other portions of the rotor adjacent the marking portion, thereby forming physical differences in the rotor, which, being visually perceptible, form the custom marking.

One exemplary embodiment of a brake rotor includes a cheek member, an intermediate portion, and a hub member. The intermediate portion may be located between the cheek and hub members, and may extend from either the cheek member or the hub member. The intermediate portion may have an exposed section with multiple openings located in the exposed section. The intermediate portion may also have multiple blades extending from inner surfaces of all or some of the openings. The blades cause airflow to pass through the openings to cool the intermediate portion.

A method of manufacturing a non-ferrous, light metal alloy vibration-damped part for a vehicle chassis includes introducing a polymer insert into a cavity formed in the part. The polymer insert may be introduced into the cavity by separately fabricating the polymer insert and then sliding or maneuvering the insert into the cavity or by injecting a liquid polymer material into the cavity and then solidifying and shrinking the liquid polymer material into the polymer insert. The vibration-damped light metal alloy part can damp vibrations that originate within or are imparted to the part when such vibrations effectuate relative contacting frictional movement between an exterior surface of the polymer insert and an interior surface of the cavity.

A ferritically nitrocarburized rotational member of a vehicle brake is disclosed, including a rotational member having a friction surface configured for braking engagement with a corresponding friction material. A compound zone is disposed at the friction surface. An exposed surface of the compound zone is exposed to an atmosphere. The area of the exposed surface includes from about 0 percent to about 14 percent graphite.

The apparatus of the present invention provides a brake rotor assembly. The brake rotor assembly includes a generally annular rotor having a frictional surface and a radially inner rotor flange defining a plurality of rotor teeth. The brake rotor assembly also includes a hub section integrally formed onto the rotor. The hub section has a peripheral hub flange configured to engage the plurality of rotor teeth and thereby prevent rotation of the hub section relative to the rotor. The rotor is preferably composed of a first material such as steel or cast iron, and the hub section is preferably composed of a second material such as aluminum or magnesium that is lighter by volume than the first material. Accordingly, the overall weight of the rotor assembly is less than that of a comparable rotor assembly composed entirely of steel or cast iron.

The present invention includes high strength, high temperature and strain rate applications of a zinc-base alloy including about 83 to 94 weight percent zinc, about 4 to about 11 percent copper and about 2 to about 4 percent aluminum. The composition may also include minor components such as magnesium and impurities. The alloy is used to construct automotive components which are subject to an instantaneous load of between 40-500 MPa. The alloy is particularly suitable for constructing components which are subject to such loads under high temperatures. In fact, components constructed from the alloy become much stronger at higher temperatures under sudden stress.
