Description

Die Erfindung betrifft ein Drehgestell für schnellfahrende Schienenfahr­zeuge, bei dem die Radsätze mittels an den Achslagern angreifenden Dop­pel-Federblattlenkern am Drehgestellrahmen angebunden und geführt sind, zwischen Doppel-Federblattlenker und Achslager oder Drehgestellrahmen elastische Zwischenlager vorgesehen sind und zwischen jedem Achslager und dem Drehgestellrahmen eine vertikale Primärfeder angeordnet ist.The invention relates to a bogie for high-speed rail vehicles, in which the wheel sets are connected and guided on the bogie frame by means of double spring leaf links acting on the axle bearings, elastic intermediate bearings are provided between double spring leaf links and axle bearings or bogie frame, and a vertical primary spring between each axle bearing and the bogie frame is arranged.

Drehgestelle der vorstehend genannten Art sind beispielsweise aus der DE-PS 17 55 072 bekannt. Hierbei sind die Langträger des Drehgestellrah­mens über Federn auf die mittels je zwei in verschiedenen Ebenen überein­ander angeordneten, zueinander parallelen Federblattlenker geführten Achslagergehäuse der Radsätze abgestützt, wobei die den Achslagergehäusen abgewandten Enden der Federblattlenker mit einem Festbock als Teil des Drehgestellrahmens spiel- und reibungsfrei fest verbunden sind. An jedem Achslagergehäuse ist hierbei ein in Längsrichtung waagerecht zwischen die freien Enden der Lenkerblätter reichendes Angußauge mit senkrechten, sich symmetrisch nach oben und unten erweiternden Bohrung und einer in dieser befindlichen Buchse aus elastischem Material angebracht und konzentrisch zu der Buchse von oben und unten Klemmringe mit einem außen kegeligen Mantel einsetzbar, deren kleine Stirnflächen einander zugewandt und an deren obere und untere äußere größere Stirnflächen mittels einer Dehn­schraube die freien Enden der Lenkerblätter andrückbar sind, wobei die Klemmringe und die freien Lenkerblätterenden zu einer sich über die Buchse gegenüber dem Achslagergehäuse abstützenden Einheit zusammenfügbar sind. Durch diese Anordnung werden die Laufeigenschaften eines Schienenfahrzeugs bei hohen Geschwindigkeiten durch die nachgiebige Halterung der Feder­blattlenker-Befestigung am Achslagergehäuse verbessert, weil eine gewisse selbsttätige Radialeinstellung der Radsätze erreichbar ist. Durch die Anordnung der Gummizwischenlager ist der Resonanzbereich des Drehgestells in einen Geschwindigkeitsbereich verlegbar, der erfahrungsgemäß in kurzer Zeit beim Anfahren durchfahrbar ist, das heißt, der nicht der Reisege­ schwindigkeit des Schienenfahrzeugs entspricht. Der Resonanzbereich ist dadurch exakt einstellbar, daß die Klemmringe in axialer Richtung einander angenähert oder voneinander entfernt festgestellt werden, wobei eine mehr oder weniger starke Verformung der aus elastischem Material bestehenden Buchse stattfindet.Bogies of the type mentioned above are known for example from DE-PS 17 55 072. Here, the long girders of the bogie frame are supported by springs on the axle bearing housings of the wheel sets, each of which is arranged in two mutually parallel, spring leaf links, the ends of the spring leaf links facing away from the axle bearing housings being firmly connected with a fixed bracket as part of the bogie frame without play and friction . On each axle bearing housing there is a sprue eye that extends horizontally in the longitudinal direction between the free ends of the handlebar blades with a vertical bore that symmetrically widens upwards and downwards and a bushing made of elastic material located therein and concentric with the bushing from above and below with a clamping ring externally conical jacket can be used, the small end faces facing each other and on the upper and lower outer larger end faces the free ends of the handlebar blades can be pressed on by means of an expansion screw, the clamping rings and the free handlebar blade ends being able to be joined together to form a unit which is supported by the bushing relative to the axle bearing housing . This arrangement improves the running properties of a rail vehicle at high speeds due to the flexible mounting of the spring leaf link mounting on the axle bearing housing, because a certain automatic radial adjustment of the wheel sets can be achieved. The arrangement of the rubber intermediate bearings means that the resonance range of the bogie can be relocated to a speed range that experience has shown that it can be driven through in a short time when moving off, that is, not the travel area speed of the rail vehicle corresponds. The resonance range can be adjusted precisely in that the clamping rings are moved closer or closer to one another in the axial direction, with the bushing made of elastic material being deformed to a greater or lesser extent.

Diese vorbekannte Radsatzführung stellt einen Kompromiß aus stabilem, relativ ruhigem Radsatzlauf in der Geraden und einem möglichst verschleiß­und kräftearmem Lauf im Bogen dar, da eine längsstarre Radsatzführung bei hoher Laufstabilität in der Geraden nur eine geringe radiale Einstellung der Radsätze im Bogen ergibt, wogegen bei einer längsweichen Radsatzfüh­rung die Laufstabilität und damit die Höchstgeschwindigkeit sehr stark herabgesetzt wird zur Erzielung einer wesentlich verbesserten radialen Einstellung der Radsätze und niedrigen Spurführungskräften im Bogen. Es wird also zur Erzielung einer hohen Geschwindigkeit in der Geraden eine möglichst starre Längsanlenkung der Radsätze gewählt. Dieses wiederum führt zu einer schlechteren Radialeinstellung der Radsatze im Bogen und damit zu höheren Spurführungskräften und größerem Spurkranzverschleiß. Soll dagegen die Radialeinstellung der Radsätze verbessert werden, wird eine Verminderung des stabilen, ruhigen Geradeauslaufs der Radsätze in der Geraden und damit eine niedrigere Höchstgeschwindigkeit in Kauf genommen.This known wheel set guidance represents a compromise between stable, relatively quiet wheel set running in the straight line and a run that is as wear-resistant and low-power as possible in the curve, since a longitudinally rigid wheel set guide with high running stability in the straight line results in only a slight radial adjustment of the wheel sets in the curve, whereas with a longitudinally soft one The stability of the wheelset and thus the maximum speed is very much reduced in order to achieve a substantially improved radial setting of the wheelsets and low tracking forces in the curve. In order to achieve a high speed in the straight line, the most rigid longitudinal linkage of the wheel sets is chosen. This in turn leads to poorer radial adjustment of the wheel sets in the bend and thus to higher tracking forces and greater wear on the flange. If, on the other hand, the radial setting of the wheel sets is to be improved, a reduction in the stable, smooth straight running of the wheel sets in the straight line and thus a lower maximum speed are accepted.

Die Aufgabe vorliegender Erfindung bestand darin, bei einem Drehgestell der eingangs genannten Art das vorstehend geschilderte gegensätzliche Laufverhalten in der Geraden und im Schienenbogen durch geeignete, ein­fache konstruktive Maßnahmen aufzuheben und bei einem stabilen ruhigen Geradeauslauf in der Geraden bei Höchstgeschwindigkeiten eine Radialein­stellung der Radsätze im Schienenbogen bei niedrigen Spurführungskräften zu erreichen.The object of the present invention was to eliminate the above-described opposite running behavior in the straight line and in the rail curve by suitable, simple constructive measures in a bogie of the type mentioned above, and with a stable, smooth straight line running in the straight line at maximum speeds, a radial adjustment of the wheel sets in the rail curve to achieve low tracking forces.

Gemäß der Erfindung wird diese Aufgabe bei einem Drehgestell der eingangs genannten Art dadurch gelöst, daß zwischen den Federblattlenkern jeden Doppel-Federblattlenkers ein die horizontalen Längsbewegungen zwischen Achslager und Drehgestellrahmen dampfender Schlingerdämpfer angeordnet ist. Hierbei kann gemäß einem Ausführungsbeispiel der Erfindung der Schlingerdämpfer als doppelt wirkender Hydrodämpfer ausgebildet sein. Gemäß anderen Ausführungsbeispielen der Erfindung ist der Schlingerdämpfer als Reibdämpfer ausgebildet. Bei Verwendung eines Hydrodämpfers als Schlingerdämpfer ist dieser mit seinem einen Ende am Achslager und mit seinem anderen Ende am Drehgestellrahmen befestigt. Bei Verwendung eines Reibdämpfers als Schlingerdämpfer ist dieser gemäß einem Ausführungsbei­spiel zwischen den Federblattlenkern auf das Lager des Doppel-Federblatt­lenkers wirkend ausgebildet, das mit dem elastischen Zwischenlager ver­sehen ist. Hierbei ist der Reibdämpfer einerseits an den Doppel-Feder­blattlenker und andererseits am Achslager oder am Drehgestellrahmen befestigt.According to the invention, this object is achieved in a bogie of the type mentioned in that a horizontal longitudinal movements between the axle bearing and bogie frame damping anti-roll damper is arranged between the spring leaf links of each double spring leaf link. Here, according to an embodiment of the invention Anti-roll damper can be designed as a double-acting hydraulic damper. According to other exemplary embodiments of the invention, the roll damper is designed as a friction damper. When using a hydraulic damper as a roll damper, it is attached at one end to the axle bearing and at the other end to the bogie frame. If a friction damper is used as a roll damper, according to one exemplary embodiment, this is designed to act between the spring leaf links on the bearing of the double spring leaf link, which is provided with the elastic intermediate bearing. The friction damper is attached to the double spring leaf link on the one hand and to the axle bearing or to the bogie frame on the other.

Bei einem dritten Ausführungsbeispiel besteht der Reibdämpfer aus minde­stens zwei einstellbar gegeneinander verspannten Blattfedern, die an ihren Längsenden beidseitig gegen in Drehgestellängsrichtung angeordnete Reib­flächen des Achslagergehäuses und/oder des Drehgestellrahmens anliegen.In a third exemplary embodiment, the friction damper consists of at least two adjustable leaf springs which bear against one another on their longitudinal ends against friction surfaces of the axle bearing housing and / or the bogie frame arranged in the longitudinal direction of the bogie.

Durch eine weiche Ausbildung des elastischen Zwischenlagers kann eine fast ideale radiale Einstellung der Radsätze bis zu den im Personenfernverkehr kleinsten Bogenradien von 250 m bei einer guten Gleichverteilung der Radsatzführungskräfte am vor- und nachlaufenden Radsatz erreicht werden. Ebenfalls können mit der erfindungsgemäßen Ausbildung des Drehgestells jetzt höhere Geschwindigkeiten in größeren Bögen gefahren werden, da genügend Reserven für die Aufnahme von dynamischen Führungskräften infolge Gleislagefehlern vorhanden sind. Der Spurkranzverschleiß wird deutlich verringert. Durch die Anordnung der Schlingerdämpfer bleiben die für einen stabilen, ruhigen Radsatzlauf in der Geraden erforderlichen Radsatzfüh­rungskräfte erhalten.Thanks to a soft design of the elastic intermediate bearing, an almost ideal radial adjustment of the wheel sets down to the smallest radius of curvature of 250 m in long-distance passenger transport can be achieved with a good uniform distribution of the wheel set executives on the leading and trailing wheel set. Likewise, with the design of the bogie according to the invention, higher speeds can now be driven in larger arches, since there are sufficient reserves for the accommodation of dynamic managers as a result of track position errors. Wheel flange wear is significantly reduced. The arrangement of the anti-roll damper means that the wheelset guidance forces required for stable, quiet wheel set running in the straight line are retained.

Die Radsätze 1 des Drehgestells sind über ihre Achslager 2 und an diesen horizontal angeordnete Doppel-Federblattlenker 3 am Drehgestellrahmen 4 angebunden und geführt. Die beiden Federblattlenker jeden Doppel-Feder­blattlenkers 3 sind dabei am Drehgestellrahmen 4 über Zahnplatten 5 einstellbar und starr befestigt. Am Achslager 2 sind die Federblattlenker jeden Doppel-Federblattlenkers 3 ebenfalls über Zahnplatten 6 jedoch unter Zwischenschaltung von elastischen Zwischenlagen 7 einstellbar befestigt. Mittels einer Dehnschraube 8, die die beiden Federblattlenker am Achsla­gergehäuse befestigt, sind die Gummizwischenlagen 7 exakt vorspannbar. Durch eine entsprechend gewählte Vorspannung der Dehnschraube 8 ist wiederum die horizontale Längssteifigkeit der Gummizwischenlage 7 genau einstellbar. Zwischen den beiden Federblattlenkern des Doppel-Federblatt­lenkers 3 ist ein Hydrodämpfer 9 angeordnet, der mit seinem einen Ende am Drehgestellrahmen 4 und mit seinem anderen Ende am Achslager 2 gelenkig befestigt ist. Der Hydrodämpfer, der doppelwirkend ausgebildet ist, wirkt somit in horizontaler Längsrichtung zwischen Drehgestellrahmen und Achs­lagergehäuse.The wheelsets 1 of the bogie are connected and guided on the bogie frame 4 via their axle bearings 2 and on these double spring leaf links 3 arranged horizontally. The two spring leaf links of each double spring leaf link 3 are adjustable on the bogie frame 4 via toothed plates 5 and rigidly attached. The spring leaf links of each double spring leaf link 3 are also fixed to the axle bearing 2 via toothed plates 6 but with the interposition of elastic intermediate layers 7. The rubber intermediate layers 7 can be precisely preloaded by means of an expansion screw 8, which fastens the two spring leaf links to the axle bearing housing. The horizontal longitudinal stiffness of the rubber intermediate layer 7 can in turn be precisely adjusted by an appropriately selected prestressing of the expansion screw 8. A hydraulic damper 9 is arranged between the two spring leaf links of the double spring leaf link 3 and is articulated at one end to the bogie frame 4 and at the other end to the axle bearing 2. The hydraulic damper, which is double-acting, thus acts in the horizontal longitudinal direction between the bogie frame and the axle bearing housing.

Bei dem in den Figuren 4 und 5 dargestellten Ausführungsbeispiel der Erfindung ist der Radsatz ebenfalls über das Achslagergehäuse 2 und Doppel-Federblattlenker 3 am Drehgestellrahmen 4 horizontal angebunden und geführt. Der Doppel-Federblattlenker 3 ist dabei wie bei dem in den Figuren 2 und 3 beschriebenen Ausführungsbeispiel der Erfindung am Dreh­gestellrahmen 4 und am Achslager 2 befestigt. Zwischen den Zahnplatten 6 und dem Achslagergehäuse 2 sind ebenfalls elastische Zwischenlager 7 angeordnet. Zwischen den Zahnplatten 6 und einem horizontalen Flansch 2a des Achslagergehäuses 2 sind bei diesem Ausführungsbeispiel der Erfindung Tellerfedern 10 vorgesehen, die Reibringe 11 beidseitig gegen Reibbeläge 12 des Flansches 2a des Achslagergehäuses 2 anpressen. Über die Dehn­schraube 8 sind die Tellerfedern 10 und damit die Anpreßkraft der Reib­fläche 11 auf dem Reibbelag 12 einstellbar. Zahnplatten 6 und Dehnschraube 8 sind mit Spiel in einer Bohrung 13 des Flansches 2a des Achslagergehäu­ses 2 geführt, so daß die erforderliche Ausschwenkung des Radsatzes mit dem Achslager 2 bei Radialeinstellung des Radsatzes im Bogenlauf möglich ist.In the exemplary embodiment of the invention illustrated in FIGS. 4 and 5, the wheel set is likewise connected and guided horizontally on the bogie frame 4 via the axle bearing housing 2 and double spring leaf link 3. The double spring leaf link 3 is fastened to the bogie frame 4 and to the axle bearing 2 as in the exemplary embodiment of the invention described in FIGS. 2 and 3. Between the tooth plates 6 and the axle bearing housing 2, elastic intermediate bearings 7 are also arranged. In this exemplary embodiment of the invention, disc springs 10 are provided between the tooth plates 6 and a horizontal flange 2a of the axle bearing housing 2 and press the friction rings 11 on both sides against friction linings 12 of the flange 2a of the axle bearing housing 2. The plate springs 10 and thus the contact pressure of the friction surface 11 on the friction lining 12 can be adjusted via the expansion screw 8. Toothed plates 6 and expansion screw 8 are guided with play in a bore 13 in the flange 2a of the axle bearing housing 2, so that the required swiveling out of the wheel set with the axle bearing 2 is possible with the wheel set being set radially in the arc.

Bei dem in den Figuren 6 und 7 dargestellten Ausführungsbeispiel der Erfindung ist der Radsatz 1 wieder über das Achslagergehäuse 2 und Dop­pel-Federblattlenker 3 am Drehgestellrahmen 4 horizontal befestigt und geführt. Zwischen den beiden Federblattlenkern des Doppel-Federblattlen­kers 3 sind zwei gewölbte Federblätter 15 angeordnet, die an ihren Längs­enden seitlich gegen in Drehgestellängsrichtung angeordnete Reibflächen 16 des Achslagergehäuses 2 und Reibflachen 17 des Drehgestellrahmens 4 anliegen. Die Reibflächen 16 und 17 sind zweckmäßig mit einem Reibbelag versehen. In ihrer Längsmitte werden die beiden Federblätter 15 mittels einer Stellschraube 18 so gegeneinander verspannt, daß ein definierter Anpreßdruck auf die Reibflächen 16 und 17 entsteht. Seitliche Führungs­stege 19 des Achslagergehäuses 2 und Führungsstege 20 des Drehgestellrah­mens führen die Federblätter 15.In the embodiment of the invention illustrated in FIGS. 6 and 7, the wheel set 1 is again fastened and guided horizontally on the bogie frame 4 via the axle bearing housing 2 and double spring leaf link 3. Between the two spring leaf links of the double spring leaf link 3, two curved spring leaves 15 are arranged, which abut laterally at their longitudinal ends against friction surfaces 16 of the axle bearing housing 2 and friction surfaces 17 of the bogie frame 4 arranged in the longitudinal direction of the bogie. The friction surfaces 16 and 17 are expediently provided with a friction lining. In the longitudinal center thereof, the two spring leaves 15 are braced against one another by means of an adjusting screw 18 such that a defined contact pressure is exerted on the friction surfaces 16 and 17. Lateral guide webs 19 of the axle bearing housing 2 and guide webs 20 of the bogie frame guide the spring leaves 15.
