Abstract

A method of making a vehicle brake rotor is provided, including manufacturing a friction ring with an opening, an annular flange projecting axially relative to a face of the friction ring, and a plurality of spaced lugs projecting radially from the flange. A hub is manufactured with a plurality of recesses integrally upon the friction ring. Next, the hub is manufactured or machined so that outermost ends of the lugs are visible from an exterior of the hub.

Claims (33)

1. A method of making a vehicle brake rotor, comprising:

manufacturing a friction ring with an opening, an annular flange projecting axially relative to a face of the friction ring, and a plurality of spaced lugs projecting radially from the flange;

manufacturing a hub with a plurality of recesses integrally upon said friction ring so that outermost ends of said lugs are not visible from an exterior of said hub; and

then manufacturing said hub on said friction ring so that said outermost ends of the lugs are visible from an exterior of said hub.

2. The method of claim 1 , wherein the friction ring is made of gray iron.

3. The method of claim 1 , wherein the lugs of the friction ring are concentric with the recesses on the hub, and are spaced equidistantly.

4. The method of claim 1 , wherein the flange defines the opening.

5. The method of claim 1 , wherein said lugs are generally cylindrical in shape and matingly engage with said recesses.

6. The method of claim 1 , wherein said hub is manufactured integrally upon said friction ring by embed casting.

7. The method of claim 6 , wherein said hub is provided with an endcap covering said opening.

8. The method of claim 6 , wherein the hub is made of aluminum.

9. The method of claim 1 , wherein manufacturing said hub on said friction ring so that said lugs are visible from an exterior of said hub occurs by machining said hub.

10. A method of making a vehicle brake rotor, comprising:

manufacturing a friction ring with an opening, an annular flange projecting axially relative to a face of the friction ring, and a plurality of spaced lugs projecting radially from the flange;

manufacturing a hub with a plurality of recesses integrally upon said friction ring so that outermost ends of said lugs are not visible from an exterior of said hub; and

then manufacturing said hub on said friction ring so that said outermost ends of the lugs are visible from an exterior of said hub,

wherein the hub is made of aluminum, and,

wherein manufacturing said hub on said friction ring so that said lugs are visible from an exterior of said hub occurs by machining said hub.

11. The method of claim 10 , wherein the friction ring is made of gray iron.

12. The method of claim 10 , wherein the lugs of the friction ring are concentric with the recesses on the hub, and are spaced equidistantly.

13. The method of claim 10 , wherein the flange defines the opening.

14. The method of claim 10 , wherein said lugs are generally cylindrical in shape and matingly engage with said recesses.

15. The method of claim 10 , wherein said hub is manufactured integrally upon said friction ring by embed casting.

16. The method of claim 15 , wherein said hub is provided with an endcap covering said opening.

17. A method of making a vehicle brake rotor, comprising:

manufacturing a friction ring with an opening, an annular flange projecting axially relative to a face of the friction ring, and a plurality of spaced lugs projecting radially from the flange;

manufacturing a hub with a plurality of recesses integrally upon said friction ring so that outermost ends of said lugs are not visible from an exterior of said hub; and

then manufacturing said hub on said friction ring so that said outermost ends of the lugs are visible from an exterior of said hub,

wherein said lugs are generally cylindrical in shape and matingly engage with said recesses, and,

wherein the friction ring is made of gray iron.

18. The method of claim 17 , wherein the lugs of the friction ring are concentric with the recesses on the hub, and are spaced equidistantly.

19. The method of claim 17 , wherein said hub is manufactured integrally upon said friction ring by embed casting.

20. The method of claim 19 , wherein manufacturing said hub on said friction ring so that said lugs are visible from an exterior of said hub occurs by machining said hub.
