Railway applications - Braking - Empty-loaded changeover devices
This document is applicable to empty-loaded changeover devices. The purpose of such devices is the generation of a load-related signal which causes the brake performance to be adjusted to the current vehicle mass.
The manually operated empty-loaded changeover devices change their output signal according to the position of the handles which together with the associated changeover plates serve as interfaces. The changeover plates read the required information for the operation of the empty-loaded changeover devices, i.e. brake weights for each position and the relevant changeover mass of the vehicle.
Automatic empty-loaded changeover devices sense a certain load threshold of the vehicle to automatically adjust the output signal when the mass of a vehicle reaches a defined value. This threshold is the changeover mass. Below this mass the vehicle’s brake system provides a reduced brake force. For the changeover mass or more the high brake force applies.
This document specifies the requirements for the design, testing and quality assurance of empty-loaded changeover devices.

Applications ferroviaires - Freinage - Dispositifs de changement de régime vide-chargé
Le présent document s’applique aux dispositifs de changement de régime « Vide-Chargé ». La finalité de ces dispositifs est la production d’un signal dépendant de la charge qui permet l’ajustement des performances de freinage à la masse effective du véhicule.
Les dispositifs de changement de régime « Vide-Chargé » à commande manuelle modifient leur signal de sortie selon la position des poignées qui, avec les plaques de commutation associées, servent d’interfaces. Les plaques de commutation indiquent les valeurs nécessaires lors de l’exploitation des dispositifs de changement de régime « Vide-Chargé », c’est-à-dire les masses freinées pour chaque position et la masse de changement de régime correspondante du véhicule.
Les dispositifs de changement de régime Vide-Chargé automatiques détectent un certain seuil de charge du véhicule afin d’ajuster automatiquement le signal de sortie lorsque la masse du véhicule atteint une valeur déterminée. Ce seuil est la masse de changement de régime. En dessous de cette masse, le système de freinage du véhicule fournit un effort de freinage réduit. Pour la masse de changement de régime ou pour une masse supérieure, l’effort de freinage élevé est appliqué.
Le présent document spécifie les exigences relatives à la conception, aux essais et à l’assurance qualité des dispositifs de changement de régime « Vide-Chargé ».
