Description

Die Erfindung betrifft eine Radsatzführung eines Drehgestells mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a wheelset guide of a bogie with the features of the preamble of claim 1.

Die Führung von Radsätzen kann unabhängig von der Primärfederung durch diskrete Elemente, durch Zusammenwirken der Führungselemente mit der Primärfeder oder durch eine entsprechende ausgebildete Primärfeder z.B. in Form einer Winkelblock-Gummischichtfeder, oder Gummirollfeder erfolgen.Independently of the primary suspension, the guidance of wheel sets can be done by discrete elements, by interaction of the guide elements with the primary spring or by a correspondingly designed primary spring e.g. in the form of an angle block rubber layer spring, or rubber roll spring.

In einer Vielzahl von Anwendungsfällen liegen die für Traktion und Radsatzführung erforderlichen Steifigkeiten nur in geringem Maße über der bei einer entsprechend ausgebildeten Schraubenfederung vorhandenen Flexicoil-Steifigkeit.In a large number of applications, the stiffnesses required for traction and wheelset guidance are only slightly above the Flexicoil stiffness available with a suitably designed coil suspension.

Aufgabe der Erfindung ist es, eine Radsatzführung, deren aus der Primärfeder herrührende Steifigkeiten durch ein Zusatzelement ergänzt werden, zu schaffen.The object of the invention is to provide a wheelset guide, the stiffnesses resulting from the primary spring are supplemented by an additional element.

Diese Aufgabe wird mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst. Fortbildungen und vorteilhafte Ausführungen der Erfindung sind in den weiteren Ansprüchen umfaßt.This object is achieved with the features of the characterizing part of claim 1. Developments and advantageous embodiments of the invention are included in the further claims.

Erfindungsgemäß erfolgt bei einer Radsatzführung eines Drehgestells, bestehend aus der einzeln oder paarweise an einem Lagergehäuse eines Radsatzes angeordneten Schraubenfeder der Primärfederung und einem einzeln oder paarweise angeordnetem Gummielement die Führung des Radsatzes durch die Flexicoilwirkung der Schraubenfedern und die Radialsteifigkeit des Gummielements gemeinsam.According to the invention, in a wheel set guidance of a bogie, consisting of the coil spring of the primary suspension arranged individually or in pairs on a bearing housing of a wheel set and a single or paired rubber element, the guidance of the wheelset through the flexicoil effect of the coil springs and the radial rigidity of the rubber element together.

Das Gummielement ist vorzugsweise als vorgespanntes, konzentrisch ausgebautes Konuselement ausgeführt, dessen Druck-Vorspannung des durch das Eigengewicht des Fahrzeugs erreicht wird und der Konizitätswinkel so gewählt wird, daß in keinem Betriebszustand Zugspannungen im Gummielement auftreten.The rubber element is preferably designed as a pretensioned, concentrically constructed cone element, the pressure prestressing of which is achieved by the weight of the vehicle and the conicity angle is selected such that tensile stresses do not occur in the rubber element in any operating state.

Das Gummielement ist unterhalb der Primärfederung auf oder z.B. in einem Hohlraum in dem Radsatzlagergehäuse gelagert und mit einem abwärts gerichteten Notführungszapfen des Drehgestellrahmens verbunden.The rubber element is below the primary suspension on or e.g. stored in a cavity in the wheelset bearing housing and connected to a downward emergency guide pin of the bogie frame.

Unterschiede in Längs- und Quercharakteristik der Führung werden durch entsprechende Ausbildung des Gummielements mit örtlich angeordneten Luftkammern erreicht. Durch Anordnung der Luftkammern in einem vorausberechneten Winkel wird eine fliehkraftabhängige Radialeinstellung der Radsätze erreicht.Differences in the longitudinal and transverse characteristics of the guide are achieved by designing the rubber element with locally arranged air chambers. By arranging the air chambers at a pre-calculated angle, a centrifugal force-dependent radial setting of the wheel sets is achieved.

Die Winkellage des Gummielements wird vorteilhafterweise über eine Nut in dessen äußeren Ring und einen schraubbaren Zapfen in einem Hohlraum des Radsatzlagergehäuses fixiert und in dem Hohlraum sind mehrere in der Höhe versetzt angeordnete Gewindebohrungen mit jeweils unterschiedlicher Winkellage vorhanden und ermöglichen eine einfache nachträgliche Anpassung an wechselnde Einsatzbedingungen.The angular position of the rubber element is advantageously fixed via a groove in its outer ring and a screwable pin in a cavity of the wheelset bearing housing and in the cavity there are several threaded holes arranged at different heights, each with a different angular position, and allow easy subsequent adaptation to changing operating conditions.

Fig. 1 zeigt ein Drehgestell 1 mit Drehgestellrahmen 2, Radscheibe 3, Radsatzlager 4 und Radsatzlagergehäuse 5. Zwischen dem Radsatzlagergehäuse 5 und dem Drehgestellrahmen 2 sind Schraubenfedern 6 als Primärfederung angeordnet. Die Schraubenfedern 6 stützen sich auf dem Radsatzlagergehäuse 5 auf Grundplatten 11 ab. In passenden Hohlräumen 12 im Radsatzlagergehäuse 5 unterhalb der Grundplatten 11 sind konusförmige Megi-Federn (Gummi-Metall-Federn) 7 fest gelagert. Die Megi-Federn 7 besitzen zentrale Zapfen 9, die durch Bohrungen in den Grundplatten 11 nach oben ragen und mit innerhalb der Schraubenfedern 6 nach unten gerichteten Notführungszapfen 8 des Drehgestellrahmens 2 drehfest verbunden sind. Die Megi-Federn 7 sind geschnitten zur Hälfte um 90° versetzt gezeichnet, so daß teilweise das volle Gummimaterial und teilweise Luftkammern 10 erkennbar sind.1 shows a bogie 1 with bogie frame 2, wheel disc 3, wheelset bearing 4 and wheelset bearing housing 5. Coil springs 6 are arranged as primary suspension between the wheelset bearing housing 5 and the bogie frame 2. The coil springs 6 are supported on the wheelset bearing housing 5 on base plates 11. In suitable cavities 12 in the wheelset bearing housing 5 below the base plates 11, conical mega springs (rubber-metal springs) 7 are firmly mounted. The mega springs 7 have central pins 9 which protrude upwards through holes in the base plates 11 and are connected in a rotationally fixed manner to emergency guide pins 8 of the bogie frame 2 which are directed downward within the coil springs 6. The mega springs 7 are shown cut half offset by 90 °, so that partly the full rubber material and partly air chambers 10 can be seen.

Erfindungsgemäß werden die Megi-Federn 7 so angeordnet, wie in Fig. 2 und Fig. 3 gezeigt. Hier sind außer der Radscheibe 3 und dem Drehgestellrahmen 2 alle oben beschriebenen Elemente des Drehgestells weggelassen. In Fig. 2 sind die Luftkammern 10 der Megi-Federn 7 symmetrisch vorne und hinten in Fahrtrichtung angeordnet, so daß sich in dieser Richtung eine weichere Charakteristik ergibt, als im lateralen Bereich. Eine besonders vorteilhafte Anordnung der Luftkammern 10, insbesondere für Gleisradien unterhalb der Grenze der radialen Selbsteinstellung des Radsatzes, zeigt Fig. 3. Hier sind die Luftkammern 10 um einen Winkel zwischen 5°und 60° zur Längsachse des Drehgestells einwärts zur Fahrtrichtung verdreht eingesetzt. Bei der Bogenfahrt wirken je nach Richtung Fliehkräfte F₁ oder F₂ auf den Drehgestellrahmen und werden über die Primärfederung und die Megi-Federn 7 gemeinsam auf den Radsatz übertragen. Dabei ergibt die verdrehte Einstellung der Luftkammern der Megi-Federn eine Charakteristik, die in Vektorkräften V₁ oder V₂ resultiert, die die Selbsteinstellung der Radsätze unterstützt.According to the invention, the mega springs 7 are arranged as shown in FIGS. 2 and 3. Here, except for the wheel disc 3 and the bogie frame 2, all the elements of the bogie described above are omitted. 2, the air chambers 10 of the mega springs 7 are arranged symmetrically at the front and rear in the direction of travel, so that there is a softer characteristic in this direction than in the lateral region. A particularly advantageous arrangement of the air chambers 10, in particular for track radii below the limit of the radial self-adjustment of the wheel set, is shown in FIG. 3. Here, the air chambers 10 are inserted rotated inwards to the direction of travel by an angle between 5 ° and 60 ° to the longitudinal axis of the bogie. During the bow ride act depending on the direction of centrifugal forces F₁ or F₂ on the bogie frame and are transmitted via the primary suspension and the mega springs 7 together on the wheelset. The twisted setting of the air chambers of the mega springs gives a characteristic that results in vector forces V₁ or V₂, which supports the self-adjustment of the wheel sets.
