CLAIMS

What is claimed is:

1. 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 tone ring on the deposition surface of the brake rotor using the additive manufacturing process machine from a second material dissimilar to the first material such that a brake rotor assembly is formed.

2. The method of claim 1 wherein the step of building up the tone ring comprises using an electron beam deposition.

3. The method of claim 1 wherein the step of building up the tone ring comprises using a laser deposition.

4. The method of claim 1 wherein the first material is a first metal and the second material is a second metal.

5. The method of claim 4 wherein the first metal is selected from a group of metals consisting of: iron, iron alloy, or a combination thereof; and the second metal is selected from a group of metals consisting of: steel or stainless steel, or a combination thereof.

6. The method of claim 1 wherein the second material is a corrosion resistant material.

7. The method of claim 6 wherein the second material is magnetic.

8. The method of claim 1 further comprising the step of treating the deposition surface of the brake rotor portion to facilitate the buildup of the tone ring comprises mechanical roughing of the deposition surface.

9. The method of claim 8 wherein the step of treating the deposition surface of the brake rotor portion to facilitate the buildup of the tone ring comprises chemical treating of the deposition surface.

10. A brake rotor assembly comprising:

a brake rotor portion formed from a first material, the brake rotor portion comprising:

a rotor disc; and

an inner circumferential portion integrally formed with the rotor disc, the inner circumferential portion comprising at least one sidewall having an inner surface and a top edge forming a deposition surface and an inwardly extending mounting flange forming a surface; and

a tone ring formed from a second material different than the first material, the tone ring comprising:

an engagement surface to be deposited on and coupled to the deposition surface of the brake rotor portion; and

a sensor surface opposite the engagement surface, wherein the second material is magnetic.

11. The brake rotor assembly of claim 10 wherein the surface of the inwardly extending mounting flange comprises a deposition surface and a mounting surface, wherein the mounting surface comprises bore.

12. The brake rotor assembly of claim 10 wherein the sensor surface comprises a plurality of protrusions.

13. The brake rotor assembly of claim 10 wherein the first material is at least one of an iron or an iron alloy and the second material is at least one of steel or stainless steel.

14. The brake rotor assembly of claim 11 further comprising a bonding layer deposed between the deposition surface and the engagement surface.

15. A vehicle comprising:

at least one wheel with an anti-lock braking system;

the wheel comprising a brake rotor assembly where the brake rotor assembly comprises:

a brake rotor portion formed from a first material, the brake rotor portion comprising:

a rotor disc; and

an inner circumferential portion integrally formed with the rotor disc, the inner circumferential portion comprising at least one sidewall having an inner surface and an inwardly extending mounting flange forming a deposition surface and a mounting surface; and

a tone ring formed from a second material different than the first material, the tone ring comprising:

an engagement surface to be deposited on and coupled to the deposition surface of the inwardly extending mounting flange; and

a sensor surface opposite the engagement surface, wherein the second material is magnetic.

16. The vehicle of claim 15 wherein the first material at least one of an iron or an iron alloy and the second material is stainless steel.
