Title
(EN) DRUM BRAKE ACTUATOR
(FR) ELEMENT DE COMMANDE DE FREIN A TAMBOUR
Abstract
(EN) Actuating mechanism (1) for a drum brake having provision for operating the brake in either a service brake mode or a park brake mode. The mechanism (1) includes a piston-cylinder assembly (9) which is located between two abutments (13, 15) at respective opposite ends (5, 6) of the brake shoe (3) and which is operable to spread those ends apart to apply the brake in the service mode of operation. The mechanism (1) also includes a pivotally mounted lever (19) which is rotated in one direction during the park brake mode of operation and in so doing coacts with one of the shoe abutments (15) and simultaneously pushes the piston-cylinder assembly(9) against the other abutment (13). The assembly (9) therefore functions as part of the lever (19) for the purpose of spreading the shoe ends (5, 6) and applying the brake in the park brake mode.
(FR) On décrit un mécanisme de commande (1) de frein à tambour permettant l'utilisation du frein pour le mode de freinage en marche ou pour le mode de freinage en stationnement. Le mécanisme (1) comprend un ensemble piston/cylindre (9) situé entre deux butées (13, 15) situées à des extrémités opposées respectives (5, 6) du sabot de frein (3) et qui sert à écarter lesdites extrémités afin d'appliquer le frein dans le mode de freinage en marche. Le mécanisme (1) comprend également un levier (19) monté pivotant que l'on fait tourner dans un sens donné dans le mode de freinage en stationnement, et qui de ce fait coopère avec l'une des butées de sabot (15) et en mème temps pousse l'ensemble piston/cylindre (9) contre l'autre butée (13). L'ensemble (9) fonctionne donc en tant que partie du levier (19) afin d'écarter les extrémités des sabots (5, 6) et d'appliquer le frein dans le mode de freinage en stationnement.
