LIGHTWEIGHT BRAKE ROTOR AND COMPONENTS WITH COMPOSITE MATERIALS

TECHNICAL FIELD
[0001] The field to which the disclosure generally relates includes methods of joining different materials and products made therefrom.

...

1. A method comprising:
placing a first insert and a second insert in a casting mold so that the first insert and second insert are in spaced-apart relationship in the mold, each of the first insert and the second insert comprising a first material;
casting a molten second material into the casting mold so that the second material flows between the first insert and the second insert and solidifying the second material to provide a product comprising a ***cast over*** body portion with the first insert and second insert, the ***cast over*** body portion comprising the second material and so that the second material is mechanically locked or metallurgically bonded to the first material and so that one or both of the first insert and the second insert provides working surface(s) for the product.

5. A method as set forth in claim 1 wherein the first insert comprises a first annular brake disc and wherein the second insert comprises a second annular brake disc and wherein the second material comprises a hub and a cast over body portion extending between the first insert and the second insert and wherein the brake rotor is a disc brake rotor and wherein the first braking surface is provided by an outer surface of the first insert, and further comprising a second braking surface provided by an outer surface of the second insert, and wherein the brake rotor is either solid or vented.

Auf der dazugehörigen Zeichnung sieht man die beiden durch Stäbe verbundenen Einlegeteile (Rundscheiben), und auf dem vorderen Einlegeteil befindet sich ein Art Aufsatz (Nabe), der cast over body portion.
