Corrosion resistant cast-in insert exciter ring

摘要

A rotational element for a wheel comprises a cast iron segment and an anti-lock brake system exciter ring adhering to the cast iron segment as a cast-in insert. The anti-lock brake system exciter ring is made of a material having greater corrosion resistance and a higher melting point than the cast iron. The exciter ring includes at least a first tang penetrating the cast iron segment. The exciter ring is preferably made from ferritic stainless steel. For disk brake systems the rotational element serves as a disk brake rotor. In vehicles using drum brakes the rotational element serves as a wheel hub.
