Abstract

Montage comportant au moins un capteur de rotation de roue, un circuit délivrant la vitesse circonferentielle de roue, des circuits à seuil délivrant des signaux de régulation, un circuit délivrant une vitesse de référence et un circuit logique de commande d'électrovalves. La vitesse circonférentielle déterminée d'une roue (vroue ) est comparée à un seuil prédéterminable dans un comparateur 16. L'équipement de régulation de la pression de freinage est déconnecté en cas de dépassement dudit seuil par la vitesse de roue et en présence simultanée d'un signal de régulation de glissement pendant un temps prédéterminable.Assembly comprising at least one wheel rotation sensor, a circuit delivering the circumferential wheel speed, threshold circuits delivering regulation signals, a circuit delivering a reference speed and a logic circuit for controlling solenoid valves. The determined circumferential speed of a wheel (vwheel) is compared with a predetermined threshold in a comparator 16. The brake pressure regulation equipment is disconnected if said threshold is exceeded by the wheel speed and in the simultaneous presence of 'a slip regulation signal for a predetermined time.
