Abstract
(EN)
A drum braking system having a spindle and backing plate affixed thereto. The system includes a drum rotating on the spindle. The drum has an inside surface with integral notches that are machined or cast into the drum. When the brakes are applied, brake shoes are actuated to contact the inside surface to create drag between the drum and the spindle. A sensor is fixed with respect to the spindle or backing plate that detects the notches when the drum rotates about the spindle. A portion of the inside surface with the integral notches is shared with the brake shoes so that applying the brakes prevents buildup that could contact the sensor. The sensor is positioned radially to reduce the effect of drum endplay on detecting of the notches.

La présente invention concerne un système de freinage à tambour présentant une broche et une plaque de support fixée à cette dernière. Le système comprend un tambour tournant sur la broche. Le tambour présente une surface intérieure avec des encoches intégrées qui sont usinées ou coulées dans le tambour. Lorsque les freins sont appliqués, des segments de frein sont actionnés pour entrer en contact avec la surface intérieure pour créer une traînée entre le tambour et la broche. Un capteur est fixé par rapport à la broche ou à la plaque de support qui détecte les encoches lorsque le tambour tourne autour de la broche. Une partie de la surface intérieure avec les encoches intégrées est partagée avec les segments de frein de sorte que l'application des freins empêche l'accumulation qui pourrait entrer en contact avec le capteur. Le capteur est positionné radialement pour réduire l'effet du jeu d'extrémité du tambour lors de la détection des encoches.
