Abstract

Un tel appareil est disposé entre un générateur de pression de freinage (un robinet de frein par exemple) et un cylindre de frein de roue, il est ajustable en fonction de la charge sur l'essieu correspondant et il laisse parvenir, suivant son ajustement, une partie plus ou moins grande de la pression du générateur à ce cylindre de frein. Selon l'invention, l'appareil de réglage de la pression de freinage 3 est composé d'un régulateur d'effort de freinage 4 qui est ajustable automatiquement en fonction de la charge ou régulateur ALB et d'une valve réductrice de pression 5 et la courbe de pression de la valve 5 est superposée à celle du régulateur ALB 4.Such a device is placed between a brake pressure generator (a brake valve for example) and a wheel brake cylinder, it is adjustable according to the load on the corresponding axle and it allows, depending on its adjustment, to arrive. a greater or lesser part of the pressure from the generator to this brake cylinder. According to the invention, the braking pressure adjustment device 3 is composed of a braking force regulator 4 which is automatically adjustable as a function of the load or ALB regulator and of a pressure reducing valve 5 and the pressure curve of valve 5 is superimposed on that of ALB 4 regulator.
