Abstract:
A carrier device for a friction pad that is utilized in a braking assembly for retarding rotational motion of a rotating object, said carrier device comprising:a carrier body adapted to be coupled to a brake actuating mechanism for pressing said carrier body toward a rotating object, said carrier body having a sector portion configured to span a circumferential portion of the rotating object when positioned adjacent thereto, said sector portion having a front end adapted to be positioned toward oncoming rotation of the rotating object and a back end positioned opposite said front end on said sector portion; said carrier body being configured so that the value of the local natural angle frequency varies between said front end and said back end of said sector portion for avoiding brake squeal; a brake shoe formed at a front side of said carrier body, said brake shoe having a contact surface configured to receivably engage a friction pad that is adapted for repeated engagement with the rotating object; a spar web formed at a back side of said brake shoe and extending away therefrom; and a bending stiffness along said sector portion of said carrier body being varied for causing said varied local natural angle frequency between said front end and said back end of said sector portion of said carrier body for avoiding brake squeal; wherein said carrier device has a substantially constant mass distribution along said sector portion of said carrier body.
