Abstract

L'invention concerne un véhicule utilitaire comprenant au moins un essieu avant et au moins un essieu arrière. Un premier circuit de frein pneumatique (2) est apparié audit au moins un essieu arrière, un second circuit de frein pneumatique est apparié audit au moins un essieu avant, et au moins une entrée d'alimentation (7) d'une unité de vannes (5) pour alimenter des cylindres de frein (6) dudit au moins un essieu arrière est reliée au premier circuit de frein (2). Chaque entrée d'alimentation (7) est reliée au premier circuit de frein (2) via une vanne d'arrêt respective (8), et les vannes d'arrêt (8) sont de plus reliées à un autre circuit pneumatique de telle sorte que, par commutation des vannes d'arrêt (8), l'unité de vannes (5) est alimentée en air comprimé à partir du premier circuit de frein (2) ou à partir de l'autre circuit pneumatique, une ligne de commande électrique (9) et/ou une ligne de commande pneumatique (10) reliant l'unité de vannes (5) à un émetteur de valeur de frein du second circuit de frein.
