Bi-metal disc brake rotor and method of manufacturing |
摘要 |
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. |

1. A friction damped disc brake rotor, comprising:
at least one rotor cheek having an insert positioned therein, said insert having a generally annular body with a plurality of tabs extending from the body, and wherein a portion of each tab is bonded with the rotor cheek and the body is separated from the rotor cheek by a ceramic coating so that the body provides a proper interfacial boundary with the cheek for damping while the bonding of the tabs with the rotor cheek prevents corrosion-causing exterior elements from reaching the interfacial boundary. |
