    • A composite brake drum particularly adapted for motor vehicle applications. The brake drum includes a reinforcement assembly embedded within the cylindrical portion of the drum. The 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. The composite brake drum is fabricated by pouring iron into the mold and then finish machining operations are performed.
    • 一种特别适用于机动车应用的复合制动鼓。 制动鼓包括嵌入滚筒的圆筒部分内的加强组件。 加强组件优选地由钢丝材料制成,并且包括在制动鼓圆柱形部分内轴向间隔开的多个圆形闭合环。 轴向延伸的定位线被机械地紧固到加强环并且用于定位环。 可以在定位器线上形成循环,以将加强组件定位在铸模模腔内,以使得装置能够在模具内基本上自定位。 复合制动鼓通过将铁浇注到模具中而完成加工操作。
