A composite brake drum particularly adapted for motor vehicle applications. me brake drum includes a reinforcement assembly embedded within the cylindrical portion of the drum. me reinforcement assembly is preferably made from steel wire stock and includes a plurality of circular closed rings spaced axially within the brake drum cylindrical portion. Axially extending locator wires are mechanically fastened to the reinforcing rings and serve to locate the rings. Loops can be formed on the locator wires for positioning the reinforcement assembly within a casting mold cavity to enable the device to be essentially self-locating within the mold. me composite brake drum is fabricated by pouring iron into the mold and then finish machining operations are performed. |
