  • Publication number: 20070062664
    Abstract: The invention provides a method for manufacturing a powertrain component enclosure member, including the steps of: (A) positioning at least one insert into a mold, wherein the insert is provided with a coating to prevent bonding between the insert and the casting material; and (B) casting a wall of the powertrain component enclosure member in the mold around the insert such that a major portion of the insert is substantially non-bonded with the casting material to provide a proper interfacial boundary with the casting material for damping.

  • Publication number: 20070062768
    Abstract: The invention provides a method for manufacturing a friction damped disc brake rotor, including the steps of: (A) providing a ceramic coating on an insert, wherein the insert has a body with tabs extending therefrom to hold the insert in a desired position within a mold; (B) washing the ceramic coating off of the tabs; (C) positioning the insert into the mold; and (D) casting a rotor cheek of the disc brake rotor in the mold around the insert such that a portion of each tab is bonded with the rotor cheek, and such that the coating is substantially non-bonded with the rotor cheek so that the coating provides a proper interfacial boundary between the body and the cheek for damping, and the at least partial bonding of each tab with the rotor cheek prevents corrosion-causing exterior elements from reaching the interfacial boundary when the friction damped disc brake rotor is in use.

  • Publication number: 20070023240
    Abstract: A Coulomb friction damped disc brake caliper bracket, wherein damping is provided by Coulomb friction, most preferably at the outboard tie-bar thereof. In one form, at least one clamping member applies compressive force externally to the caliper bracket, and in a second form, at least one interfacial boundary is internally disposed in the caliper bracket. Provided thereby is a mechanically distinguishable surface boundary between two surfaces which are in mutual contact such that a state of Coulomb friction exists therebetween.

  • Publication number: 20060076200
    Abstract: A Coulomb friction damped disc brake rotor, wherein damping is provided Coulomb friction in generally coextensive relation with the braking surfaces of the one or more rotor cheeks. The Coulomb friction damped disc brake rotor has at least one interfacial boundary formed in at least one rotor cheek disposed in generally coextensive relation to the braking surface thereof. The interfacial boundary provides a mechanically distinguishable surface boundary between two surfaces which are in mutual contact such that a state of Coulomb friction exists therebetween.
