Abstract
L'invention concerne un dispositif antidérapage pour circuit de freinage. Elle se rapporte à un dispositif qui comprend des capteurs détectant les vitesses de rotation de deux roues d'au moins un essieu, et des comparateurs qui déterminent la plus grande et la plus petite des valeurs des signaux des détecteurs. La valeur la plus grande est atténuée et parvient à un dispositif intégrateur à mémoire dont l'autre entrée reçoit le signal d'un décéléromètre qui a subi une atténuation suivant un pourcentage identique au pourcentage d'atténuation du signal du comparateur transmettant le plus élevé des signaux. Le signal de sortie du dispositif intégrateur à mémoire est relié à un comparateur qui reçoit aussi le signal le plus petit et qui permet la commande d'une électrovanne destinée à relâcher les freins lorsque l'une des roues a atteint un seuil de glissement. Application aux circuits de freinage des véhicules à moteur.
