Railway applications - Wheelsets and bogies - Wheels - Tread profile

This European Standard defines the tread profiles of wheels with a diameter greater than or equal to 330 mm used on vehicles running on European standard gauge track to fulfil interoperability requirements. These profiles apply to new wheels, whether free-standing or assembled as wheelsets, as well as to wheels that require reprofiling during maintenance. Any profile that does not conform to this standard shall only be used following agreement between the train operator and the infrastructure manager.

Bahnanwendungen - Radsätze und Drehgestelle - Räder - Radprofile

Die vorliegende Europäische Norm definiert die Laufprofile für Räder mit einem Durchmesser größer oder
gleich 330 mm, die für Ausrüstungen verwendet werden, die auf normalen europäischen Gleisen verkehren,
um die Interoperabilität abzusichern. Diese Profile werden sowohl für neue Räder, als Einzelteile geliefert oder
zu Radsätzen montiert, als auch für zu reprofilierende Räder im Rahmen der Instandhaltung angewendet.
Jedes Profil, das nicht konform zu dieser Norm ist, kann nur nach Vereinbarung zwischen dem Betreiber und
dem Infrastrukturmanager angewandt werden.

Applications ferroviaires - Essieux montés et bogies - Roues - Profil de roulement

La présente Norme Européenne définit les profils de roulement des roues de diamètre supérieur ou égal à 330 mm utilisées pour des matériels circulant sur voie normale européenne et qui permettent d’assurer l’interopérabilité. Ces profils s’appliquent aux roues neuves livrées sous forme de roues seules ou calées sur essieux montés, ainsi qu’aux roues devant subir un reprofilage en cours de maintenance.
Tout profil non conforme à la présente Norme fait l’objet d’un accord entre utilisateur et le gestionnaire d’infrastructure.

Železniške naprave - Kolesne dvojice in podstavni vozički - Kolesa - Profil tekalne površine

Ta evropski standard določa profile tekalnih površin koles s premerom, večjim od ali enakim 300 mm, uporabljenih pri vozilih, ki vozijo po evropskih standardnih tirih, da so izpolnjene zahteve za medobratovanje. Ti profili veljajo za nova kolesa ali samo stoječa ali sestavljena v kolesne dvojice in za kolesa, ki potrebujejo ponovno profiliranje med vzdrževanjem. Vsak prosil, ki ni v skladu s tem standardom, se lahko uporablja samo po dogovoru med operaterjem vlaka in upravljavcem infrastrukture.

EN 13715:2006+A1:2010 (E) 4 Introduction This standard states requirements that are in accordance with the principles adopted by the International Union of Railways. It:  describes the rules, parameters and construction methods of the wheel tread profile;  defines the geometry of the flange and reverse slope.
The thicknesses and height of the flange are determined by the railway undertaking or its representative in compliance with the normative documents in force;
 defines the co-ordinates and geometry of the following three reference tread profiles of the wheels and their reverse slope:  1/40th (reverse slope 15 %);  S1002 (reverse slope 6,7 %, other value used 15 %) in conformity with UIC Leaflet 510-2;  EPS (reverse slope 10 %) equivalent to profile P8 of the United Kingdom with a flange 30 mm thick. These three reference profiles are defined in Annexes B, C and D and represent original profiles from the time of their design, the flanges having been harmonized to a 32,5 mm flange thickness.  defines the tolerances needed to achieve calibration control. All the dimensions in this standard are given in millimetres. SIST EN 13715:2006+A1:2011

4.1 Definition of the profiles The profiles comprise:  two zones H2 – S and S – D1, with fixed geometry;  a connection zone D1 – C1, unique to each of them, to make a tangential connection at point C1;  a zone C1 – B1 (either B1a, or B1b) unique to each of them. The co-ordinates are given in Annexes B, C and D for the three reference profiles including point D0;  a zone B1 (either B1a or B1b) – A1 – I, comprising the reverse slope and chamfer, unique to each reference profile. The reverse slope shall be in the range 6,7 % to 15 %. 5 Construction method 5.1 Definition of the axes The Y axis is parallel to the axis of rotation of the wheel with the positive values towards the external face of the wheel.
The Z axis is perpendicular to the latter with the positive values towards the outside of the wheel.
Their origin is at point D0, situated 70 mm from the internal face of the wheel. 5.2 Base profile The base profile is that obtained with a flange 32,5 mm thick and 28 mm high. All the others are developed from this fundamental profile. 5.3 Profile construction 5.3.1 Profile zone H2 – D1 (flange) The reference flange (dimensions, centres and radii) is given in Annex A for a flange thickness of 32,5 mm.
The different flange thicknesses are obtained by translating the zones S-D1, parallel to the Y axis, towards the internal face of the wheel. Annex A gives all the co-ordinates for flange thicknesses between 28,5 mm and 32,5 mm.
After translation, the connection axis (AXB) at the tip of the flange (S) is at a distance, in mm, from the wheel internal face of: ae=−−153252, SIST EN 13715:2006+A1:2011

32,5 mm 5.3.3.1 S1002 and 1/40th profiles For flange thicknesses greater than 28,5 mm, but less than 32,5 mm, the profiles are obtained by translating the zones D1-C1 (connection zone) and C1-T1 along the Y axis towards the internal face of the wheel, by an amount equal to the reduction (de) in thickness of the flange. The position of the point T1 is defined relative to the reference point D0 for all flange thicknesses. The connection between points D0 and T1 may be smoothed by a straight line.
