Abstract
A brake rotor assembly is provided. The brake rotor assembly includes a brake rotor portion formed from a first material. A tone ring formed from a second material is coupled to the brake rotor portion. The tone ring is formed by an additive manufacturing process, a subtractive manufacturing process, or a combination thereof. The brake rotor portion may be cast from an iron or iron alloy. The tone ring is formed by an additive manufacturing, or 3D printing, process machine from a second material that is corrosion resistive, such as, for example, stainless steel.
Claims16
A method for producing a brake rotor assembly having a brake rotor portion and a tone ring, the method comprising:
- obtaining a brake rotor portion of a brake rotor assembly made from a first material, the brake rotor portion comprising a rotor disc and an inner circumferential portion formed with the rotor disc wherein a top edge of the inner circumferential portion forms a deposition surface, the inner circumferential portion including an inwardly extending mounting flange;
- placing the brake rotor portion into a work station of an additive manufacturing process machine;
- building up a cylindrical member on the deposition surface of the brake rotor using the additive manufacturing process machine from a second material dissimilar to the first material;
- and
- removing material from the cylindrical member to form a plurality of channels and a corresponding plurality of protrusions to form the tone ring of an integrated brake rotor with an integral tone ring.
A method for producing a brake rotor assembly having a brake rotor portion and a tone ring having a plurality of protrusions forming teeth of the tone ring, the method comprising:
- providing a brake rotor portion of the brake rotor assembly made from a first material, the brake rotor portion comprising a rotor disc and an inner circumferential portion having a raised platform having a deposition surface;
- and;
- building only the teeth of the tone ring directly on the deposition surface from a second material dissimilar to the first material using an additive manufacturing process;
- wherein the tone ring consists solely of the teeth built from the second dissimilar material.
