Abstract

Un système de freinage adaptable pour wagons à marchandises, notamment des wagons-citernes à quatre essieux utilisés dans la circulation transfrontalière, doit pouvoir fonctionner avec deux pressions de freinage et deux rapports des leviers différents. A cet effet, une vanne de commande (41, 51) avec des réservoirs auxiliaires d'air (42, 52) est associée aux parties pneumatiques de chaque système de freinage. Les vannes de commande des deux systèmes de freinage, qui peuvent être coupées du conduit principal d'air, ainsi que les réservoirs auxiliaires d'air qui leur sont associés, peuvent être alternativement reliées au cylindre de freinage (1), à la manière d'un robinet à trois voies (50). Dans la partie mécanique des systèmes de freinage, des tirants (21) peuvent être montés sur des points d'articulation alternatifs (E, F) entre les leviers compensateurs horizontaux (8, 9) afin d'adapter les rapports de puissance et des leviers au système de freinage respectif. Des glissoirs montés sur les deux parties des tirants du frein principal permettent d'articuler les tirants du frein principal sur des points d'appui situés à des hauteurs et des longueurs diverses des dispositifs de freinage des bogies pour voies normales et larges.
