Description

Die Erfindung betrifft ein Laufwerk für Schienenfahrzeuge nach dem Oberbegriff des Patentanspruches 1.The invention relates to a running gear for rail vehicles according to the preamble of claim 1.

Durch die DE-A- 1 455 178 ist eine Achsführung für Schienenfahrzeuge bekannt geworden, bei der das Achslagergehäuse zu seinen beiden Seiten auf von ihm abstehenden Konsolen elastische Abstützungen trägt, die an der Unterseite des Fahrgestellrahmens bzw. des Drehgestelles ein Widerlager haben und die Radstöße und Achsschwingungen dämpfen. Die elastischen Abstützungen bestehen aus je einem Gelenkblock aus einem elastischen Gummi- bzw. Kunststoffmaterial, welcher aus einem die in vertikaler Richtung verlaufenden Achsstöße aufnehmenden elastischen Gelenkblockteil und einem die in horizontaler Richtung auftretenden Achsschwingungen aufnehmenden elastischen Gelenkblockteil besteht.From DE-A-1 455 178 an axle guide for rail vehicles has become known in which the axle bearing housing carries elastic supports on both sides on brackets projecting from it, which have an abutment on the underside of the chassis frame or the bogie and the wheel joints and dampen axle vibrations. The elastic supports each consist of an articulated block made of an elastic rubber or plastic material, which consists of an elastic articulated block part that receives the vertical joints and an elastic articulated block part that receives the axis vibrations that occur in the horizontal direction.

Ziel der Erfindung ist die Schaffung eines Laufwerkes, welches insbesondere für rasch laufende Schienenfahrzeuge bestimmt ist, die auch für hohe Geschwindigkeiten, z.B. über 160 km/h, geeignet sind und geringe Rad-Schienen-Kräfte und geringen Rad-Schiene-Verschleiß aufweisen, wofür die Achsführung der beschriebenen bekannten Bauart keine zufriedenstellenden Ergebnisse bringt.The aim of the invention is to create a drive which is intended in particular for fast-running rail vehicles which can also be used at high speeds, e.g. above 160 km / h, are suitable and have low wheel-rail forces and low wheel-rail wear, for which the axis guidance of the known design described does not produce satisfactory results.

Unter Laufwerken sind sowohl die entsprechenden Teile eines Starrahmenfahrzeuges als auch die von Drehgestellen eines Drehgestellfahrzeuges zu verstehen. Im folgenden wird die Erfindung nur mehr am Beispiel von Drehgestellen erläutert.Undercarriages are understood to mean both the corresponding parts of a rigid frame vehicle and those of bogies of a bogie vehicle. In the following the invention will only be explained using the example of bogies.

Im allgemeinen sind Drehgestelle, die für hohe Geschwindigkeiten geeignet sind, mit Radsätzen ausgerüstet, die relativ steif mit dem Drehgestellrahmen, hauptsächlich in X-Richtung (Fahrtrichtung), verbunden sind, um instabilen Lauf vermeiden zu können.In general, bogies that are suitable for high speeds are equipped with wheelsets that are relatively rigidly connected to the bogie frame, mainly in the X direction (direction of travel), in order to avoid unstable running.

Diese Drehgestelle haben durch die relativ starre Anlenkung der Radsätze am Rahmen nicht die Möglichkeit der Radsätze, sich bei Fahrt im Bogen radial einzustellen. Aus diesem Grund sind einerseits die Kräfte zwischen Rad und Schiene und der Verschleiß zwischen Rad und Schiene höher als bei Drehgestellen, deren Radsätze nicht relativ steif, sondern längselastisch mit dem Drehgestellrahmen verbunden sind und die sich bei Bogenfahrt teilweise oder vollständig radial einstellen können.Due to the relatively rigid articulation of the wheel sets on the frame, these bogies do not have the possibility of the wheel sets moving themselves set radially in the curve. For this reason, on the one hand, the forces between the wheel and the rail and the wear between the wheel and the rail are higher than with bogies, the wheelsets of which are not relatively stiff but are connected to the bogie frame in a longitudinally elastic manner and which can partially or completely adjust radially when traveling on bends.

Drehgestelle, die vorzugsweise geringe Kräfte und geringen Rad-Schiene-Verschließ auch bei Bogenfahrt aufweisen sollen, werden u.a. mit Radsätzen ausgerüstet, die relativ elastisch (weich) mit dem Drehgestellrahmen, vorzugsweise in X-Richtung (Fahrtrichtung), verbunden sind. Dadurch haben die Radsätze die Möglichkeit, sich bei Bogenfahrt radial einzustellen, wodurch die Kräfte zwischen Rad und Schiene sowie der Verschleiß zwischen Rad und Schiene vermindert werden.Bogies, which should preferably have low forces and low wheel-rail locking even when traveling through bends, are equipped, among other things, with wheel sets that are relatively elastically (softly) connected to the bogie frame, preferably in the X direction (direction of travel). This enables the wheel sets to adjust radially when traveling through bends, which reduces the forces between the wheel and the rail and the wear between the wheel and the rail.

Derartige Drehgestelle mit längselastischen Radsätzen sind nicht oder nur mit Zusatzeinrichtungen für hohe Geschwindigkeiten von z.B. über 160 km/h geeignet.Such bogies with longitudinally elastic wheelsets are not or only with additional devices for high speeds of e.g. suitable for speeds above 160 km / h.

Aufgabe der Erfindung ist die Schaffung einer Einrichtung, mit der es möglich ist, je nach Erfordernis, vorzugsweise auch während der Fahrt, von einer weichen (längselastischen) auf eine relativ starre Anlenkung der Radsätze umzuschalten bzw. beliebige Zwischenstufen in der Anlenksteifigkeit zwischen Radsätzen und Drehgestellrahmen zu ermöglichen.The object of the invention is to provide a device with which it is possible, depending on the requirements, preferably also while driving, to switch from a soft (longitudinally elastic) to a relatively rigid articulation of the wheel sets or any intermediate stages in the articulation stiffness between the wheel sets and the bogie frame to enable.

Die Lösung dieser Aufgabe wird durch die Maßnahme nach dem kennzeichnenden Teil des Patentanspruches 1 erreicht. Dadurch ist es möglich, je nach Erfordernis, die Radsätze entweder relativ starr oder längselastisch (weich) mit dem Rahmen des Fahrwerks zu verbinden.This object is achieved by the measure according to the characterizing part of patent claim 1. This makes it possible, depending on the requirement, to connect the wheel sets to the frame of the undercarriage either relatively rigidly or with longitudinal elasticity (soft).

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen 2 bis 12.Further features and advantages of the invention result from subclaims 2 to 12.

Die Ausführungsform des Laufwerkes nach den Fig. 1 - 4 besitzt ein Drehgestell 1, welches zwei in der Fahrtrichtung liegende Seitenwangen 2 aufweist, die in der Längsmitte durch einen Hauptträger 3 und zu beiden Seiten desselben durch je einen Bremsträger 4 verbunden sind. Mit den strichpunktierten Linien sind in Fig. 2 Radsatzachsen 5 angedeutet, welche an beiden Enden in je einem Radsatzlager gelagert sind, das in einem Radsatzlagergehäuse sitzt, welches zu beiden Seiten der Radsatzachse einen Radsatzführungszapfen 6 (Fig. 3) lagert, der in den Fig. 1 und 5 durch lotrechte, strichpunktierte Linien angedeutet ist. Ein Teil des Radsatzlagergehäuses ist in Fig. 3 mit 7 bezeichnet. Es besitzt eine Öffnung 8 zur Aufnahme eines Führungstopfes 9, der zylindrisch ausgeführt mit einer Gleitbuchse 10 ausgekleidet ist, in die eine ringförmige Buchse 11 eingesetzt ist, die einen Außenring 12 und einen Innenring 13 und dazwischen ein einvulkanisiertes, ringförmiges gummi-elastisches Element 14 besitzt, welches innenseitig, in der Fahrtrichtung gesehen, einander diametral gegenüberliegende ringsegmentförmige Aussparungen 15, 16 besitzt. Im Bereiche dieser beiden Aussparungen 15, 16 hat das gummi-elastische Element 14, wie Fig. 3 zeigt, einen trapezförmigen Querschnitt mit innenseitigen Schrägwanden 17, 19. Erfindungsgemäß sind in die Aussparungen 15 bzw. 16 der außen liegenden Buchsen Fortsätze 21 bzw. 22 eines Schiebers 23 einführbar, dessen Boden 24 mit einer mittigen Bohrung 25 zum Hindurchführen einer Kolbenstange 26 versehen ist, die im Radsatzführungszapfen 6 geführt an ihrem oberen Ende mit einem Kolben 27 verbunden ist. Der Kolben 27 ist in einem im Rahmen des Laufwerkes bzw. dessen Längswangen 2 befestigten Zylinder 28 geführt, der mit seinen Wänden 29 durch einen Preßsitz am Radsatzführungszapfen 6 aufsitzt. Der Kolben 27 steht unter dem Einfluß einer ihn nach oben drückenden Feder 30, welche als Schraubenfeder ausgebildet, einerseits auf einem Absatz 31 einer zylindrischen Öffnung des Radsatzführungs-zapfens 6 und andererseits am Kolben 27 abgestützt ist und die Tendenz hat, diesen Kolben nach oben zu drücken. Über dem Kolben 27 befindet sich ein, durch einen Zylinderdeckel 33 abgeschlossener Raum 34, welcher über eine Leitung 35 mit Druckluft gespeist wird. Die Versorgung des Raumes 34 mit Druckluft erfolgt von einem nicht dargestellten Druckluftbehälter über Leitungen 55 - 58. Anstelle einer pneumatischen kann auch eine hydraulische Anlage treten.The embodiment of the drive according to FIGS. 1-4 has a bogie 1, which has two side cheeks 2 lying in the direction of travel, which are connected in the longitudinal center by a main support 3 and on both sides thereof by a brake support 4. The dash-dotted lines in FIG. 2 indicate wheelset axles 5, which are mounted at both ends in a wheel set bearing, which is seated in a wheel set bearing housing, which has a wheel set guide pin 6 (FIG. 3) on both sides of the axle, which is supported in FIGS 1 and 5 is indicated by vertical, dash-dotted lines. A part of the wheelset bearing housing is designated 7 in FIG. 3. It has an opening 8 for receiving a guide pot 9, which is lined cylindrically with a slide bush 10, into which an annular bush 11 is inserted, which has an outer ring 12 and an inner ring 13 and between them a vulcanized, annular, rubber-elastic element 14 , which has diametrically opposed ring segment-shaped recesses 15, 16 on the inside, as seen in the direction of travel. In the area of these two recesses 15, 16, as shown in FIG. 3, the rubber-elastic element 14 has a trapezoidal cross section with inclined walls 17, 19 on the inside. According to the invention, extensions 21 and 22 are in the recesses 15 and 16 of the outer bushings of a slide 23 insertable, the bottom 24 of which is provided with a central bore 25 for the passage of a piston rod 26 which is guided in the wheel set guide pin 6 and connected at its upper end to a piston 27. The piston 27 is guided in a cylinder 28 fastened in the frame of the running gear or its longitudinal cheeks 2, the cylinder 29 with its walls 29 by a press fit Wheelset guide pin 6 is seated. The piston 27 is under the influence of a spring 30 pushing it upwards, which is designed as a helical spring, is supported on the one hand on a shoulder 31 of a cylindrical opening of the wheel set guide pin 6 and on the other hand on the piston 27 and has the tendency to move this piston upwards to press. Above the piston 27 there is a space 34 which is closed off by a cylinder cover 33 and which is fed with compressed air via a line 35. Compressed air is supplied to the room 34 from a compressed air tank (not shown) via lines 55-58. A hydraulic system can also be used instead of a pneumatic one.

Zur Abdichtung des Systems ist ein Balg 36 vorgesehen, welcher an seinem unteren Ende durch einen Klemmring 37 an einer Buchse 38 befestigt ist, die in das obere Ende des Führungstopfes 9 eingesetzt ist. Das obere Ende des Balges 36 ist an einem offenen, seitlich abstehenden Boden 39 eines Topfes 40 angeschlossen. Der Topf 40 ist mit seinem ausragenden Rand des Bodens 39 zwischen einer Schraubenfeder 41 und einem Gummiring 54 des Drehgestellrahmens bzw. der Seitenwange 2 desselben eingespannt. Die Schraubenfeder 41 dient zur vollen Aufnahme der vertikalen Führungskräfte und sitzt an ihrem unteren Ende auf einem vom Führungstopf 9 abstehenden Bund 42 auf, mit welchem sich der Führungstopf 9 über eine Beilage 43 am Radsatzlagergehäuse 7 abstützt. Am oberen Ende stützt sich die Feder 41 am ausragenden Teil des Bodens 39 des Topfes 40 ab.To seal the system, a bellows 36 is provided, which is attached at its lower end by a clamping ring 37 to a bush 38 which is inserted into the upper end of the guide pot 9. The upper end of the bellows 36 is connected to an open, laterally projecting bottom 39 of a pot 40. The pot 40 is clamped with its protruding edge of the bottom 39 between a coil spring 41 and a rubber ring 54 of the bogie frame or the side cheek 2 of the same. The helical spring 41 serves to fully accommodate the vertical executives and is seated at its lower end on a collar 42 protruding from the guide pot 9, with which the guide pot 9 is supported on the wheel set bearing housing 7 via an insert 43. At the upper end, the spring 41 is supported on the protruding part of the bottom 39 of the pot 40.

Die Kolbenstange 26 ist durch einen Bolzen 44 mit dem Boden 24 des Schiebers 23 verbunden.The piston rod 26 is connected to the bottom 24 of the slide 23 by a bolt 44.

Selbstverständlich können im Rahmen der Erfindung verschiedene konstruktive Ausgestaltungen vorgenommen werden. So besteht beispielsweise die Möglichkeit, in das gummielastische Element 14 der Buchse 11, wie Fig. 4 zeigt, zwischen den beiden Aussparungen 15 und 16 ein Blechsegment 53 einzuvulkanisieren.Of course, various structural configurations can be made within the scope of the invention. For example, there is the possibility of vulcanizing a sheet metal segment 53 into the rubber-elastic element 14 of the bushing 11, as shown in FIG. 4, between the two cutouts 15 and 16.

Wie bereits eingangs erwähnt, soll die Buchse 11 für hohe Geschwindigkeiten steif, hingegen für geringere Geschwindigkeiten, wie sie beispielsweise beim Kurvenfahren in Bögen mit kleinen Radien auftreten, weich sein. In der in Fig. 3 dargestellten Lage des Schiebers 23 ist die Buchse 11 weich eingestellt, indem die Fortsätze 21, 22 des Schiebers aus dem Bereich des gummielastischen Elementes 14 nach unten getreten sind. Diese Lage des Schiebers 23 wird durch Einlassen von Druckluft in den Raum 34 bewirkt, wodurch auch der Kolben 27 mit seiner Kolbenstange 26 in die unterste Stellung gegen den Druck der Feder 30 gelangt. Mit z.B. zunehmender Geschwindigkeit des Schienenfahrzeuges wird eine steigende Steifigkeit der Buchse 11 verlangt. Um dies zu erreichen, wird Druckluft aus dem Raum 34 abgelassen, wodurch die Feder 30 den Kolben nach oben drückt, sodaß die Fortsätze des Schiebers 21, 22 zwischen die lotrechten Flächen 70 des gummielastischen Elementes 14 und den Innenring 13 treten, bis sie die strickpunktiert dargestellte Lage eingenommen haben.As already mentioned at the beginning, the bushing 11 should be stiff for high speeds, but soft for lower speeds, such as occur, for example, when cornering in arches with small radii. In the position of the slider 23 shown in FIG. 3, the bushing 11 is softly set by the extensions 21, 22 of the slider stepping down from the area of the rubber-elastic element 14. This position of the slide 23 is brought about by admitting compressed air into the space 34, as a result of which the piston 27 with its piston rod 26 also reaches the lowest position against the pressure of the spring 30. With e.g. increasing speed of the rail vehicle, an increasing rigidity of the bushing 11 is required. To achieve this, compressed air is discharged from the space 34, whereby the spring 30 pushes the piston upward, so that the extensions of the slide 21, 22 enter between the vertical surfaces 70 of the rubber-elastic element 14 and the inner ring 13 until they dot the cord have shown position.

Bei abnehmender Geschwindigkeit des Schienenfahrzeuges wird durch neuerliches Einlassen von Druckluft in den Raum 34 der Schieber 23 mit seinen beiden Fortsätzen 21, 22 nach unten gedrückt. Diese Regelung bzw. Steuerung kann durch einen geschwindigkeitsabhängigen Regler erfolgen, welcher ein Einlaß- bzw. Auslaßventil einer pneumatischen oder hydraulischen Anlage steuert.When the speed of the rail vehicle decreases, new inlet of compressed air into the space 34 pushes the slider 23 with its two extensions 21, 22 downward. This regulation or control can be carried out by a speed-dependent controller which controls an inlet or outlet valve of a pneumatic or hydraulic system.

Vorzugsweise können die innenliegenden Buchsen 100 einer Radsatzführungseinheit immer weich und ohne Schieber 23 ausgeführt werden.Preferably, the inner bushings 100 of a wheelset guide unit can always be made soft and without a slide 23.

Bei Ausfall der Druckluft wird die außenliegende Buchse unter dem Einfluß der Feder 30 immer die harte Einstellung haben, d.h. in diesem Falle wird der Schieber 23 die strichpunktierte Lage einnehmen, was für den stabilen Lauf des Schienenfahrzeuges bei hohen Geschwindigkeiten notwendig ist.If the compressed air fails, the outer bush will always have the hard setting under the influence of the spring 30, i.e. in this case, the slider 23 will assume the dot-dash position, which is necessary for the stable running of the rail vehicle at high speeds.

Bei der Konstruktion nach den Fig. 5 - 9 trägt der Radsatzführungszapfen 6 zwei Buchsen 11A und 11B, die anstelle der Buchse 11 treten.In the construction according to FIGS. 5-9, the wheel set guide pin 6 carries two bushes 11A and 11B, which replace the bushing 11.

Der Radsatzführungszapfen 6 ist an seinem oberen Ende mit dem Drehgestellrahmen bzw. der Seitenwange 2 fix verbunden. Die Buchse 11A ist mit dem Radsatzführungszapfen 6 fest verbunden, während die darunter liegende Buchse 11B um diesen drehbar gelagert ist. Anstelle der Kolbenstange 26 ist eine Drehwelle 26A vorgesehen, welche an ihrem unteren Ende einen Mitnehmer 61 trägt, der mit Klauen 62 in den Klauen 63 der drehbaren Buchse 11B eingreift. Die Drehwelle 26 A trägt an ihrem oberen Ende einen Hebel 64, welcher mit einem Lenker 65 verbunden ist. Am Lenker 65 ist ein Lenker 66 angelenkt, der mit dem einen Ende eines doppelarmigen Schwenkhebels 67 gelenkig verbunden ist, dessen anderes Ende an einer Kolbenstange 68 eines hydraulischen oder pneumatischen Zylinders 69 angelenkt ist. Die obere feste Buchse 11A kann beliebig ausgeführt sein. Sie kann beispielsweise zwischen zwei konzentrischen Ringen ein volles Gummi-Element besitzen. Die drehbare Buchse 11B besitzt, ähnlich wie die Buchse 11, zwischen einem Außenring 12 und einem Innenring 13 ein einvulkanisiertes Gummi-Element 14, welches mit Aussparungen 15, 16 versehen ist. Die Steifigkeit der oberen festen Buchse 11A, vermehrt durch die Steifigkeit der unteren drehbaren Buchse 11B, wenn ihre Aussparungen 15, 16 mittig in der Fahrzeugrichtung X gelegen sind, wie Fig. 8 zeigt, entspricht einer weichen Einstellung, d.h. einer Einstellung für Fahrgeschwindigkeiten, die unter einer kritischen Fahrgegeschwindigkeit gelegen sind, bei welcher eine weiche Einstellung der Buchse erwünscht wird. Bei zunehmender Geschwindigkeit dreht der Steuermechanismus über die Drehwelle 26A und den Mitnehmer 61 sowie die beiden Klauensätze 62 und 63 die drehbare Buchse bis zu 90° in die in Fig. 9 dargestellte Stellung, in welcher die Summe der Steifigkeiten der festen und der drehbaren Buchse 11A bzw. 11B jener Steifigkeit entspricht, welche die Buchse 11 des vorangegangenen Ausführungsbeispieles in der strickpunktiert dargestellten Lage des Schiebers 23 hatte. Die Steuerung der drehbaren Buchse 11B kann durch einen Geschwindigkeitsregler erfolgen, welcher den Druck auf den Kolben des hydraulischen oder pneumatischen Zylinders 69 steuert.The wheelset guide pin 6 is fixedly connected at its upper end to the bogie frame or the side cheek 2. The bushing 11A is fixedly connected to the wheel set guide pin 6, while the bushing 11B lying underneath is rotatably mounted about the latter. Instead of the piston rod 26, a rotary shaft 26A is provided, which carries at its lower end a driver 61 which engages with claws 62 in the claws 63 of the rotatable bushing 11B. The rotary shaft 26 A carries at its upper end a lever 64 which is connected to a link 65. A link 66 is articulated on the link 65 and is articulated to one end of a double-armed pivot lever 67, the other end of which is articulated to a piston rod 68 of a hydraulic or pneumatic cylinder 69. The upper fixed socket 11A can be of any design. For example, it can have a full rubber element between two concentric rings. The rotatable bushing 11B, like the bushing 11, has a vulcanized rubber element 14 between an outer ring 12 and an inner ring 13, which is provided with cutouts 15, 16. The rigidity of the upper fixed bushing 11A, increased by the rigidity of the lower rotatable bushing 11B when its recesses 15, 16 are located centrally in the vehicle direction X, as shown in Fig. 8, corresponds to a soft adjustment, i.e. a setting for driving speeds which are below a critical driving speed at which a soft setting of the bushing is desired. As the speed increases, the control mechanism, via the rotary shaft 26A and the driver 61 and the two claw sets 62 and 63, rotates the rotatable bushing up to 90 ° into the position shown in FIG. 9, in which the sum of the stiffnesses of the fixed and the rotatable bushing 11A or 11B corresponds to the stiffness which the bushing 11 of the previous exemplary embodiment had in the position of the slider 23 shown in broken lines. The rotatable bushing 11B can be controlled by a speed controller which controls the pressure on the piston of the hydraulic or pneumatic cylinder 69.

Bei dieser Konstruktion sind die Steifigkeits- und Dämpfungs eigenschaften richtungsabhängig ausgebildet, indem die Buchse 11B, je nach Erfordernissen, durch die beschriebene Vorrichtung in die entsprechende Lage gedreht wird, sodaß gerade die gewünschten Steifigkeits- und Dämpfungseigenschaften in Längsrichtung (Fahrtrichtung) zwischen Radsätzen und Drehgestellrahmen zur Wirkung kommen.In this construction, the stiffness and damping are Characteristics directionally formed by the bushing 11B, depending on requirements, is rotated by the described device into the appropriate position, so that the desired stiffness and damping properties in the longitudinal direction (direction of travel) between the wheel sets and the bogie frame come into effect.
