Abstract

L'invention concerne une valve de pilotage de freinage d'un essieu de véhicule, notamment d'un essieu de remorque, comprenant un corps (100) qui comprendune entrée de commande (120) reliée à un conduit decommande principalede freinage, une entrée principale d'alimentation (130) reliée à une source de pression, une entrée secondaire (140) reliée à une pression faible (R), une sortie (150) reliée au frein de l'essieu, un piston (300) définissant une consignede force représentative de la charge sur l'essieu, et un tiroir (200) monté à translation dans une chambre (110) du corps (100) et sollicité par la pression appliquée sur l'entrée de commande (120), une rétroaction de la pression régnant sur la sortie (150), et un tarage représentatif de la charge de l'essieu, de sorte que la pression en sortie est asservie à la charge de l'essieu tout en étant proportionnelle à la pression sur l'entrée de commande (120). L'invention concerne également un procédé de pilotage, un système qui comprend la valve et les véhicules ainsi équipés.
