Title (EN) BRAKE ADJUSTER HAVING RESHAPABLE MEMBER DRAWN THROUGH A DIE
(FR) REGLAGE DE FREIN AYANT UNE PIECE REFACONNABLE PASSANT AU TRAVERS D"UNE MATRICE
Abstract: front page image
(EN)In the field of brakes, adjusters are required to maintain a constant clearance between engaging parts, even upon wear. A problem with prior adjustment devices is that they may not release the brakes because of the relationship between the static and dynamic coefficients of friction between their parts and the functioning of return spring mechanisms. The adjuster of this application draws a tube (32) through a die (48) thereby eliminating the noted problem relative to the coefficients of friction. A shaft or pin (36) is connected to the pressure plate (12) of a brake assembly and is interconnected with a reshapable tube (32). The shaft (36) and tube (32) pass through a die (48) which makes swaging engagement with the tube (32). As the brake wears, the tube (32) is drawn through the die (48) and is progressively swaged along the length thereof, The spring follower (20) acts against the die (48) to urge the die (48), tube (32) and shaft (36) to a return position following release of brake pressure.
(FR)Dans le domaine des freins, des reglages sont necessaires pour maintenir un espacement constant entre les pieces cooperantes, meme lors de l"usure. Un probleme des systemes de reglage connus reside dans le fait qu"ils peuvent ne pas desserrer les freins a cause des relations entre les coefficients de friction statique et dynamique entre leurs parties et le fonctionnement des mecanismes de ressort de rappel. Le mecanisme de reglage tire un tube (32) au travers d"une matrice (48) eliminant ainsi le probleme cite relatif aux coefficients de friction. Un arbre ou axe (36) est relie a la plaque de pression de l"assemblage du frein et est en communication reciproque avec un tube refaconnable (32). L"axe (36) et le tube (32) passent au travers d"une matrice (48) qui a embouti le tube (32) au fur et a mesure que le frein s"use, le tube (32) est tire au travers de la matrice (48) et est progressivement embouti sur la largeur de celle-ci. Le chapeau a ressort (20) agit contre la matrice (48) afin de forcer la matrice (48), le tube (32) et l"axe (36) dans une position de retour a la suite du relachement de la pression du frein.
