Abstract

Ce dispositif comprend un réducteur de pression de freinage qui contrôle par une soupape principale le passage de la conduite de frein dans un circuit de freinage, ainsi qu'un dispositif de commande formé d'un ou de plusieurs organes de distribution et piloté lui-même électriquement par des capteurs. Selon l'invention, le dispositif de commande 28, 44, 45 est pourvu, par unité à commander (cylindre de frein 8', 9' d'un distributeur à plusieurs voies 28 pour contrôler une liaison (conduite 26) entre une chambre de commande 24 et une chambre de contrepression 25 du réducteur de pression de freinage 10, ainsi que d'un cadenceur 44, 45 pour appliquer et couper de façon cadencée la pression de freinage du cylindre de frein de roueThis device comprises a brake pressure reducer which controls by a main valve the passage of the brake line in a brake circuit, as well as a control device formed of one or more distribution members and itself controlled. electrically by sensors. According to the invention, the control device 28, 44, 45 is provided, per unit to be controlled (brake cylinder 8 ', 9' with a multi-way distributor 28 to control a connection (pipe 26) between a control chamber. control 24 and a backpressure chamber 25 of the brake pressure reducer 10, as well as a timer 44, 45 for applying and steadily switching off the brake pressure of the wheel brake cylinder
