20100140033 | COMPONENT WITH INLAY FOR DAMPING VIBRATIONS - An exemplary embodiment includes an automotive brake component, such as a brake drum or a brake rotor, and an inlay coupled to the automotive brake component. The inlay constituting at least a portion of a braking surface that is acted upon during a braking event. The inlay damping vibrations in the automotive brake component when the component is vibrated. | 06-10-2010 |
20100282550 | MODE ALTERING INSERT FOR VIBRATION REDUCTION IN COMPONENTS - A component with a first number of natural modes of vibration. An insert may be coupled to the component. The insert may have a second number of natural modes of vibration which is a different number than the first number of natural modes of vibration of the component. The insert helps damp vibrations in the component when the component is vibrated. | 11-11-2010 |
20110127124 | Coulomb Friction Damped Disc Brake Caliper Bracket - A Coulomb friction damped disc brake caliper bracket, wherein damping is provided by Coulomb friction, most preferably at the outboard tie-bar thereof, by a Coulomb bar peripherally welded thereto. An inner surface of the Coulomb friction bar is in abutting contact with the external surface of the tie-bar, whereby because of the continuous peripheral edge welding, corrosion cannot find entry into the interface of the two surfaces, yet the two surfaces form are free to vibrate one as to the other in Coulomb friction fashion to thereby provide damping and reduction of brake squeal and other noise. | 06-02-2011 |
20110220313 | METHOD OF CASTING DAMPED PART WITH INSERT - A method including positioning an insert in a vertical mold including a first mold portion and a second mold portion; and casting a material including a metal around at least a portion of the insert. | 09-15-2011 |
20110220772 | METHOD OF CASTING DAMPED PART WITH INSERT - A method including positioning an insert in a vertical mold including a first mold portion and a second mold portion; and casting a material including a metal around at least a portion of the insert. | 09-15-2011 |
20110297491 | BRAKE ASSEMBLY - A brake assembly includes a brake pad, a bracket supporting the brake pad and having a first portion, a second portion spaced apart from the first portion, and a linkage interconnecting the first and second portions. The linkage is configured to transfer tensile loads between the first and second portion, but is characterized by the absence of any bending modes. The absence of bending modes prevents excitation of the linkage, thereby reducing sound generated during application of the brake assembly. | 12-08-2011 |

20130112514 | LIGHT-WEIGHT AND SOUND-DAMPED BRAKE ROTOR AND METHOD OF MANUFACTURING THE SAME - A light-weight and sound-damped brake rotor for a vehicle braking system includes a rotor hat and a rotor cheek supported by the rotor hat. The rotor hat includes an axially-protruding central hub and a flange that extends radially from and circumferentially around the central hub. The rotor cheek, which provides at least one braking surface, is formed from two or more separate and distinct pieces which are fixedly secured to the flange of the rotor hat. Located within the rotor cheek underneath the at least one braking surface is a vibration damping element. The brake rotor derives its vibration-deadening and sound-damping effects from the vibration damping element through the occurrence of relative frictional contacting movement. | 05-09-2013 |

The linkage is configured to transfer tensile loads between the first and second portion, but is characterized by the absence of any bending modes. The absence of bending modes prevents excitation of the linkage, thereby reducing sound generated during application of the brake assembly. | 10-03-2013 |
20140246162 | METHOD OF CASTING DAMPED PART WITH INSERT - A method including positioning an insert in a vertical mold including a first mold portion and a second mold portion; and casting a material including a metal around at least a portion of the insert. | 09-04-2014 |
