Patent number: 8820491Abstract: 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.Type: GrantFiled: April 26, 2011Date of Patent: September 2, 2014Assignee: GM Global Technology Operations LLCInventors: Michael D. Hanna, James G. Schroth, Richard H. Hammar, Omar S. Dessouki, Brent D. Lowe, Mark T. Riefe, Jeremy W. Short, Andrew Schertzer

Patent number: 8118079Abstract: 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.Type: GrantFiled: July 31, 2008Date of Patent: February 21, 2012Assignee: GM Global Technology Operations LLCInventors: Michael D. Hanna, Mohan Sundar, Andrew Schertzer
