Railway applications - Track - Switches and crossings for Vignole rails - Part 3: Requirements for wheel/rail interaction
This document defines the main wheel/track interaction criteria to be taken into account during the geometrical design of railway switches and crossings (S&C) layouts.
It specifies:
— characterization of wheel and track dimensions;
— geometric design principles for wheel guidance;
— design principles for wheel load transfer;
— whether movable crossings are needed.
These are illustrated by their application to turnout components:
— switches;
— crossings;
— check rails,
but the principles apply equally to more complex units. There are also simplified definitions of the safety and functional dimensions, which can be used in conjunction with the general principles as the basis for more in-depth assessment.
Bahnanwendungen - Oberbau - Weichen und Kreuzungen für Vignolschienen - Teil 3: Anforderungen an das Zusammenspiel Rad/Schiene
Dieses Dokument legt die Hauptkriterien des Zusammenspiels Rad/Schiene fest, die während der Phase des geometrischen Entwurfs von Gleisanlagen mit Eisenbahn-Weichen und Kreuzungen zu berücksichtigen sind.
Es legt Folgendes fest:
— die Beschreibung der Rad und Gleisabmessungen;
— die geometrischen Entwurfsgrundsätze für die Radführung;
— Entwurfsgrundsätze für die Radlastübertragung;
— ob Herzstücke mit beweglichen Bauteilen erforderlich sind.
Diese werden entsprechend ihrer Anwendung auf die Weichenbauteile
— Zungenvorrichtungen;
— Herzstücke;
— Radlenker;
dargestellt, jedoch sind die Grundsätze gleichermaßen auch auf umfangreichere Gleiseinheiten anwendbar. Es gibt auch vereinfachte Definitionen der Sicherheits- und Funktionsmaße, die in Verbindung mit den allgemeinen Grundsätzen als Grundlage für eine tiefergehende Bewertung angewendet werden können.
Applications ferroviaires - Voie - Appareils de voie pour rails Vignole - Partie 3 : Exigences pour l'interaction roue/rail
Le présent document définit les principaux critères concernant l'interaction roue/voie à prendre en compte lors de la conception géométrique des appareils de voie ferroviaires.
Il spécifie :
— la caractérisation des dimensions des roues et des voies ;
— les principes de conception géométrique pour le guidage des roues ;
— les principes de conception pour le transfert de la charge à la roue ;
— la nécessité ou non d'utiliser des cœurs à parties mobiles.
Ces aspects sont représentés en les appliquant aux composants de branchements suivants :
— aiguillages ;
— cœurs ;
— contre-rails.
Toutefois, les principes s'appliquent également aux appareils de voie plus complexes. Des définitions simplifiées relatives aux cotes sécuritaires et fonctionnelles peuvent en outre être utilisées conjointement aux principes généraux, dans le cadre d'une évaluation plus approfondie.
Železniške naprave - Zgornji ustroj proge - Kretnice in križišča za Vignolove tirnice - 3. del: Zahteve na stiku kolo-tirnica
Ta del tega evropskega standarda določa:
– karakterizacijo mer kolesa in tirnice;
– načela geometrijskega projektiranja za usmerjanje koles;
– načela geometrijskega projektiranja za prenos obremenitve koles;
– odločanje o tem, ali so potrebna premična križišča.
To je v tem dokumentu ponazorjeno z uporabo za sestavne dele kretniškega sistema:
– kretnice;
– križišča;
– vodilne tirnice;
vendar se načela prav tako uporabljajo za kompleksnejše postavitve.
