Railway applications - Wheelsets and bogies - Axles - Product requirements
This document specifies the characteristics of axles for all heavy rail track gauges.
This document applies to heavy rail vehicles and applies, in principle, to other vehicles such as urban rail vehicles.
It defines characteristics of forged or rolled solid and hollow axles, made from vacuum-degassed steel grade EA1N[1]), EA1T1) and EA4T1). For hollow axles, this standard applies only to those that are manufactured by machining of a hole in a forged or rolled solid axle.
The requirements defined in this standard are applicable for cylindrical seats. Most of the requirements are also applicable for axles with conical seats. Specific requirements for conical seats (e.g. geometrical dimensions of the seats…) are defined in the technical specification.
Some characteristics are given as a function of a category 1 or of a category 2.
This document is applicable to axles that are designed in accordance with the requirements of EN 13103-1:2018.
This document also permits variations of the material characteristics linked to alternative manufacturing processes (e.g. cold rolling, shot blasting, thermal spraying, steel cleanliness, reduction ratio, improved material properties from melting and heat treatment process, etc.).
1) N for a normalized metallurgical condition
T for a quenched and tempered metallurgical condition
Bahnanwendungen - Radsätze und Drehgestelle - Radsatzwellen - Produktanforderungen
Dieses Dokument legt die Eigenschaften von Radsatzwellen für alle Vollbahnspurweiten fest.
Dieses Dokument ist für Vollbahnfahrzeuge und grundsätzlich für andere Fahrzeuge wie städtische Schienenbahnen anwendbar.
Es legt Eigenschaften für geschmiedete oder gewalzte massive und längsgebohrte Radsatzwellen aus den vakuumentgasten Stahlsorten EA1N, EA1T und EA4T fest. Für längsgebohrte Radsatzwellen gilt diese Norm nur, wenn diese durch mechanische Bearbeitung der Bohrung in einer geschmiedeten oder gewalzten massiven Radsatzwelle hergestellt werden.
Die in dieser Norm festgelegten Anforderungen sind für zylindrische Radsitze anwendbar. Die meisten Anforderungen sind darüber hinaus für Radsatzwellen mit konischen Radsitzen anwendbar. Spezifische Anforderungen an konische Radsitze (z. B. geometrische Abmessungen der Radsitze) werden in der technischen Spezifikation festgelegt.
Einige Eigenschaften sind in Abhängigkeit von Kategorie 1 oder Kategorie 2 angegeben.
Dieses Dokument ist für Radsatzwellen, die in Übereinstimmung mit den Anforderungen nach CEN/EN 13103-1:2017+A1:2022 entworfen wurden, anwendbar.
Dieses Dokument erlaubt außerdem Abweichungen der Materialeigenschaften in Verbindung mit alternativen Fertigungsprozessen (z. B. Kaltwalzen, Kugelstrahlen, thermisches Spritzen, Stahlreinheit, Schmiedeverformungsgrad, Verbesserung der Werkstoffeigenschaften durch das Schmelzverfahren und den Wärmebehandlungsprozess usw.).
Applications ferroviaires - Essieux montés et bogies - Essieux-axes - Prescription pour le produit
Le présent document spécifie les caractéristiques des essieux-axes pour tous les écartements de voie des véhicules ferroviaires lourds.
Le présent document s'applique aux véhicules ferroviaires lourds et s'applique, en principe, à d'autres véhicules tels que les véhicules ferroviaires urbains.
Il spécifie les caractéristiques des essieux-axes pleins et creux, forgés ou laminés, en acier dégazé sous vide, de nuance EA1N, EA1T et EA4T. Pour les essieux-axes creux, le présent document s'applique seulement à ceux qui sont fabriqués par usinage d'un trou dans un essieu-axe plein forgé ou laminé.
Les exigences spécifiées dans le présent document sont applicables aux portées de calage cylindriques. La plupart des exigences sont également applicables aux essieux-axes à portées de calage coniques. Des exigences spécifiques pour les portées coniques (par exemple, dimensions géométriques des portées de calage, etc.) sont définies dans la spécification technique.
Quelques caractéristiques sont données en fonction d'une catégorie 1 ou d'une catégorie 2.
Le présent document est applicable aux essieux-axes qui sont conçus conformément aux exigences de l'EN 13103-1:2017+A1:2022.
Le présent document admet également des variations des caractéristiques du matériau en relation avec des procédés alternatifs de fabrication (par exemple, galetage, grenaillage, dépôt de métal par projection thermique, propreté de l'acier, taux de corroyage, propriétés améliorées du matériau par un procédé de fusion et de traitement thermique, etc.).
