Abstract

Dans ce frein à tambour, du type dans lequel les mâchoires 14 sont actionnées par une came 19 et sont articulées à l'extrémité opposée à cette came sur des axes (ou un seul axe) d'ancrage 15, les mâchoires sont montées sur les axes 15 par des encoches présentant un fond semi-cylindrique et deux bords d'entrée rectilignes. L'axe longitudinal de chaque encoche est dirigé vers l'intérieur du frein et vers le haut (vers l'axe de la roue) de sorte que la partie inférieure de chaque mâchoire forme un crochet capable de retenir la mâchoire dans le sens dans lequel elle tend à être entraîner par le mouvement du tambour.In this drum brake, of the type in which the jaws 14 are actuated by a cam 19 and are articulated at the end opposite this cam on anchoring pins (or a single pin) 15, the jaws are mounted on the axes 15 by notches having a semi-cylindrical bottom and two rectilinear entry edges. The longitudinal axis of each notch is directed towards the inside of the brake and upwards (towards the axis of the wheel) so that the lower part of each jaw forms a hook capable of retaining the jaw in the direction in which it tends to be driven by the movement of the drum.
