Abstract
A modular brake rotor includes a core having a central wall and a plurality of support ribs extending radially outwards therefrom. A pair of friction rings are secured to the support ribs. A viscoelastic vibration reducing element is disposed between the support ribs and the friction rings for creating a vibration reducing interface therebetween. The viscoelastic vibration reducing element is preferably a viscoelastic adhesive. In an alternate embodiment, the viscoelastic vibration reducing element is viscoelastic laminate including one or more layers of viscoelastic adhesive bonded to one or more intermediate materials.
Claims11
A brake rotor comprising:
- a core having a hat section and a plurality of support ribs extending therefrom;
- a pair of friction rings secured to said support ribs;
- a viscoelastic vibration reducing element disposed between said support ribs and said friction rings, wherein said viscoelastic vibration reducing element is a laminate comprising a viscoelastic adhesive and an intermediate material bonded to said viscoelastic adhesive.
A method of manufacturing a brake rotor including the steps of:
- (a) forming a rotor core including a hat section and ribs extending from said hat section;
- (b) forming annular friction rings;
- and
- (c) securing said friction rings to said rotor core with a viscoelastic vibration reducing element to create a vibration reducing interface therebetween, wherein the viscoelastic vibration reducing element is a viscoelastic laminate having a viscoelastic adhesive bonded to an intermediate material.
A method of manufacturing a brake rotor comprising forming a rotor core including a hat section and ribs extending from said hat section;
- forming annular friction rings;
- providing viscolelastic vibration reducing elements;
- placing the viscoelastic vibration reducing elements adjacent the ribs;
- and securing the friction rings to the ribs and the viscoelastic vibration reducing elements to create a vibration reducing interface between the ribs and the friction rings wherein the viscoelastic vibration reducing element is a viscoelastic laminate having a viscoelastic adhesive bonded to an intermediate material.
