Abstract
The present invention relates to a modular brake rotor having friction rings secured to a core. The core includes a hat section having a hat wall, and a plurality of circumferentially spaced apart support ribs. A pair of friction rings having inner surfaces are secured to the support rib inboard and outboard mounting surfaces. The support ribs extend into recesses formed in the inner surfaces of the friction rings to secure the friction rings to the support ribs. The ribs may include protrusions formed using dowels which extend through the support ribs and project out of the inboard and outboard mounting surfaces and into the recesses. Alternatively, the protrusions may be formed integrally with the support ribs.
Claims20
A brake rotor comprising
- a core having a hat wall and a plurality of circumferentially spaced apart support ribs extending radially outwards from said hat wall, wherein each of said support ribs includes separate inboard and outboard mounting surfaces;
- a pair of friction rings secured to said core, wherein at least one of said friction rings includes an inner surface having recesses formed therein for receiving said support ribs for fastening said at least one of said friction ring to said support rib;
- and
- an adhesive disposed between said support ribs and said friction rings for securing said friction rings to said support ribs.
A brake rotor comprising
- a core having a hat wall and a plurality of circumferentially spaced apart support ribs extending radially outwards from said hat wall, wherein each of said support ribs includes separate inboard and outboard mounting surfaces;
- and
- at least one friction ring having an inner surface with recesses formed therein for receiving said support ribs to secure said friction ring to said support ribs by a friction fit.
A method of manufacturing a brake rotor including the steps of:
- a) forming a rotor core including a hat section and support ribs extending radially outwards from the hat section and having separate inboard and outboard mounting surfaces;
- b) forming a pair of friction rings each having an inner surface and an outer surface;
- c) forming recesses in the inner surfaces of the friction rings;
- and
- d) pressing the friction rings against the support ribs so that the ribs are received in said recesses to secure the friction rings to the support ribs by a friction fit.
A method of manufacturing a brake rotor including the steps of:
- a) forming a rotor core including a hat wall and a flat annular disc extending radially from the hat wall;
- b) machining the disk to form individual, circumferentially spaced apart support ribs each having separate inboard and outboard mounting surfaces;
- c) forming annular friction rings having inner surfaces;
- and
- d) fastening the inner surfaces of the annular friction rings to the support rib inboard and outboard mounting surfaces.
