Abstract

L'invention se rapporte à un frein à tambour et mâchoires internes. Le frein comporte un dispositif de réglage comprenant un levier 16 monté à pivotant sur une mâchoire du frein 11 et un cliquet 19 chargé par un ressort qui est également articulé sur la mâchoire et coopère avec des dents d'encliquetage 18 formées sur l'arc d'un quadrant du levier. Une butée constituée par une entretoise 27 coopère avec le levier pour limiter le mouvement de retour de la mâchoire en cours de freinage. Le jeu entre la mâchoire et le tambour est contrôlé par un pivotement prédéterminé de l'une 21 des articulations tandis qu'un ressort de rappel 25 empêche ce pivotement de se produire autrement. Application à des freins d'automobiles même s'ils sont commandés mécaniquement.The invention relates to a drum brake and internal jaws. The brake comprises an adjustment device comprising a lever 16 pivotably mounted on a brake shoe 11 and a pawl 19 loaded by a spring which is also articulated on the jaw and cooperates with ratchet teeth 18 formed on the arc d 'a quadrant of the lever. A stop consisting of a spacer 27 cooperates with the lever to limit the return movement of the jaw during braking. The play between the jaw and the drum is controlled by a predetermined pivoting of one 21 of the articulations while a return spring 25 prevents this pivoting from occurring otherwise. Application to automobile brakes even if they are mechanically controlled.
