A wayside lubricator for railroad cars has a number of sensors (9, 10, 11) mounted adjacent the track which detect the approach and passage of rail cars. A lubricant supply and a pressurizing system are mounted adjacent the track and in fluid communication with a control valve and spray nozzle (12). The spray nozzle (12) is aimed to shoot lubricant into a target zone when the control valve is opened. The spray nozzle (12) is turned on for a defined duration of time so that the quantity of the lubricant is kept under control. Application of the lubricant to the wheels of the locomotive is avoided by detecting locomotive wheels and leaving the valve closed until they pass. This invention reduces the friction between the wheel tread and rail on curves for the trailing cars and thus reduces the friction and the force that is experienced by the wheel flanges on curves.
L'invention porte sur un graisseur de roues de bord de voie des roues de wagons comportant plusieurs détecteurs (9, 10, 11) montés le long de la voie et détectant l'approche et le passage des trains. Une réserve de lubrifiant et un système de mise sous pression, montés à proximité de la voie, communiquent avec des soupapes de commande et des buses de projection (12) projetant lorsque la soupape est ouverte le lubrifiant dans une zone cible pendant un temps limité, ce qui permet de doser la quantité de lubrifiant projetée. On évite la projection sur les roues de la locomotive en détectant les roues de la locomotive et en laissant la soupape fermée jusqu'à ce la locomotive soit passée. L'invention réduit le frottement entre le bandage des roues et le rail dans les courbes uniquement pour les wagons remorqués et donc le frottement et la force appliquée aux boudins dans les courbes.
