Abstract

The invention relates to a primary spring for chasses of rail vehicles, characterized in that the spring is designed as a substantially rectangular layered spring that is fitted into the bearing housing. Said fitting has two advantages: optimum force introduction into the bearing housing and an optimum low load for the elastomeric layers due to the kinematic of a link for the wheel set guide.

Description

Primarfeder primary spring
Die Erfindung betrifft eine Pπmarfeder für Fahrwerke von Schienenfahrzeugen.The invention relates to a Pπmarfeder for chassis of rail vehicles.
Für außengelagerte Fahrwerke sind eine Vielzahl an Federlosungen bekannt, wie z.B. zylindrische Schraubendruckfedern aus Stahl meist in Kombination mit einer rotationssymmetrischen Schichtfeder auf Naturkautschukbasis, Konusschichtfedern, oder auf Schub belastete Schichtfedern .Bei Fahrwerken mit Innenlagerung sind die Anforderungen an die Feder anders. So wird beispielsweise eine deutlich höhere Steifigkeit von 2000 bis 5000 N/mm im Vergleich zu 800 bis 2000 N/mm gefordert.For outboard trolleys, a variety of spring solutions are known, such as e.g. cylindrical helical compression springs made of steel usually in combination with a rotationally symmetrical layer spring based on natural rubber, conical layer springs, or on shear-loaded layer springs. For chassis with internal storage, the requirements on the spring are different. For example, a significantly higher rigidity of 2000 to 5000 N / mm is required compared to 800 to 2000 N / mm.
Bekannte Losungen mit Konusschichtfedern nutzen den Bauraum schlecht aus und stellen eine ungunstige Einbindungen xn Rahmen und Lagergehause dar. Weiterhin sind derartige Federn schwer mit einer Progression der Federkennlinie zu gestalten, wodurch eine Losung des Auslegungskonfliktes : Wankauslegung / Entgleisungssicherheit - im Fahrwerk erschwert wird.Known solutions with cone-layer springs use the space poorly and represent an unfavorable integrations xn frame and bearing housing. Furthermore, such springs are difficult to make with a progression of the spring characteristic, whereby a solution of the design conflict: Wankauslegung / derailment - is difficult in the chassis.
Durch die Quersteifigkeit und die Langssteifigkeit übernehmen diese Federn einen Anteil der Radsatzfuhrung, und müssen bei der Auslegung der Radsatzfuhrung berücksichtigt werden. Bei gewissen Auslegungen können dadurch weitere Zwange bei der Realisierung derartiger Federn entstehen.Due to the transverse rigidity and the longitudinal stiffness these springs take over a proportion of Radsatzfuhrung, and must be taken into account in the interpretation of Radsatzfuhrung. With certain interpretations, this can result in further constraints in the realization of such springs.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Pπmarfeder für Fahrwerke mit Innenlagerung anzugeben, die bei möglichst geringem Bauraum { Abstand Federmitte zu Radscheibe ) ein möglichst großes Federarbeitsvermogen aufweist. Diese Federarbeit wird insbesondere für leichte Fahrzeuge mit hoher Zuladung benotigt. Das Verhältnis Zuladung zu Eigengewicht ist ein Maß für die Wirtschaftlichkeit eines Fahrzeuges.The present invention has for its object to provide a Pπmarfeder for chassis with inner bearing, the smallest possible space {distance spring center to wheel disc) as possible has large spring work capacity. This spring work is needed especially for light vehicles with high payload. The ratio of payload to deadweight is a measure of the profitability of a vehicle.
Erfmdungsgemaß geschieht dies mit einer Feder mit rechteckiger Form. Die Feder ist eine im wesentlichen rechteckige Schichtfeder, die sich an das Lagergehause anpasst.Erfmdungsgemaß this is done with a spring with a rectangular shape. The spring is a substantially rectangular layer spring that adapts to the bearing housing.
Diese Anpassung bringt zwei Vorteile: optimale Krafteinleitung in das Lagergehause und eine optimale niedrige Belastung für die Elastomerschichten zufolge der Kinematik einer Schwinge für die Radsatzfuhrung.This adaptation has two advantages: optimum introduction of force into the bearing housing and optimum low stress for the elastomer layers as a result of the kinematics of a rocker for the wheelset guide.
Die Quer- und Langssteifigkeit der Feder ist konzeptionell derart niedrig, das eine Berücksichtigung und damit Wechselwirkungen mit der Auslegung der Radsatzfuhrung nicht gegebenThe transverse and longitudinal stiffness of the spring is conceptually so low that a consideration and thus interactions with the design of Radsatzfuhrung not given
