Abstract

L'invention concerne un régulateur d'effort de freinage en fonction de la charge pour freins actionnés par fluide de pression dans des véhicules automobiles et des remorques, dont la grandeur réglée dépend de la charge du véhicule et qui utilise une course de réglage produite par la charge et transmise par une timonerie à un levier de commande 8 sous forme d'un mouvement angulaire, lequel est transformé en un mouvement rotatif d'un arbre de commande 6 auquel est reliée l'autre extrémité du levier 8 puis, par l'intermédiaire d'une rampe de came 5, en une course d'un poussoir de soupape 1 qui s'appuie par son extrémité inférieure 4 sur la rampe 5. Selon l'invention, l'arbre 6 est en deux parties : une partie 9 portant la rampe 5 et une partie 11 portant le levier 8, et des moyens sont prévus pour établir une liaison rigide ajustable entre ces deux parties, ce qui permet de compenser des écarts dus à des tolérances de fabrication.The invention relates to a load-dependent braking force regulator for pressure fluid-actuated brakes in motor vehicles and trailers, the controlled magnitude of which is dependent on the vehicle load and which uses an adjusting stroke produced by load and transmitted by a linkage to a control lever 8 in the form of an angular movement, which is transformed into a rotary movement of a control shaft 6 to which is connected the other end of the lever 8 then, by the intermediate a cam ramp 5, in a stroke of a valve lifter 1 which rests by its lower end 4 on the ramp 5. According to the invention, the shaft 6 is in two parts: a part 9 carrying the ramp 5 and a part 11 carrying the lever 8, and means are provided for establishing an adjustable rigid connection between these two parts, which makes it possible to compensate for deviations due to manufacturing tolerances.
