Abstract

L'invention concerne un système de lubrification de rail qui représente la solution pour réduire le bruit dû à une interface rail-roue. Le système de lubrification de rail comprend un réservoir (5) de compresseur, un compresseur (5) de moteur, un boîtier de commande (6), un capteur de courbe avec GPS intégré (7), une cuve (3) de réservoir, un turbodistributeur de lubrifiant (9) et une paire de buses (1, 8). Le capteur de courbe (7), le capteur de pression (5), l'électrovanne (4) sont tous connectés au boîtier de commande (6), qui contient un contrôleur, un contrôleur PLC. Le contrôleur va réagir directement avec le capteur de courbe afin de faire passer le signal à l'électrovanne (4) pour laisser l'air provenant du réservoir (5) de compresseur circuler dans celui-ci, afin de laisser le lubrifiant à l'intérieur de la cuve (3) de réservoir circuler à travers le turbodistributeur de lubrifiant (9) et de le pulvériser sur le rail avec la buse (1, 8) des deux côtés du rail.
