  • Coulomb friction damped disc brake rotors
    Patent number: 7975750
    Abstract: A Coulomb friction damped disc brake rotor, wherein damping is provided Coulomb friction in generally coextensive relation with the braking surfaces of the one or more rotor cheeks. The Coulomb friction damped disc brake rotor has at least one interfacial boundary formed in at least one rotor cheek disposed in generally coextensive relation to the braking surface thereof. The interfacial boundary provides a mechanically distinguishable surface boundary between two surfaces which are in mutual contact such that a state of Coulomb friction exists therebetween.
    Type: Grant

  • Coulomb friction damped disc brake caliper bracket
    Patent number: 7604098
    Abstract: A Coulomb friction damped disc brake caliper bracket, wherein damping is provided by Coulomb friction, most preferably at the outboard tie-bar thereof. In one form, at least one clamping member applies compressive force externally to the caliper bracket, and in a second form, at least one interfacial boundary is internally disposed in the caliper bracket. Provided thereby is a mechanically distinguishable surface boundary between two surfaces which are in mutual contact such that a state of Coulomb friction exists therebetween.
