Description

Die Erfindung betrifft eine kombinierte Zug- und Stossvorrichtung mit Ringfeder und Elastikpatrone für Mittelpufferkupplungen von Schienenfahrzeugen, wobei die Vorrichtung in die den Kuppelkopf mit der Anlenkung am Fahrzeug verbindende Zugstange eingefügt ist oder diese ersetzt und die Elastikpatrone aus einem Rohrkörper mit einem gegen das Federmedium verschiebbaren Kolben besteht, der über eine Kolbenstange aus der Patrone herausgeführt ist.The invention relates to a combined pulling and pushing device with ring spring and elastic cartridge for central buffer couplings of rail vehicles, the device being inserted into or replacing the connecting rod connecting the coupling head to the articulation on the vehicle and the elastic cartridge from a tubular body with a piston which can be displaced against the spring medium exists, which is led out of the cartridge via a piston rod.

Zug und Stossvorrichtungen unter Verwendung von Ringfedern sind bekannt. Ringfedern sind vor allem deswegen so vorteilhaft, weil mit solchen Vorrichtungen bei relativ kleinen Federwegen relativ grosse Kräfte abgefedert werden können. Mit Ringfedern lassen sich jedoch keine Stossvorrichtungen aufbauen, welche erst oberhalb einer bestimmten Grenze ansprechen und dann den zu grossen Stoss auffangen und die bei solchen Stössen auftretenden Energien vom Fahrzeug fernhalten. Man hat daher beispielsweise in der DE-PS 19 47 819 eine Vorrichtung vorgeschlagen, welche in der Lage ist, übergrosse Stösse aufzufangen. Der Nachteil dieser Vorrichtung besteht aber darin, dass sie erst bei relativ grossen Stössen auf den Kuppelkopf ansprechen kann und nach jedem Ansprechen durch eine neue Vorrichtung ersetzt werden muss. Dieser Aufwand ist beträchtlich.Train and pushing devices using ring springs are known. Ring springs are particularly advantageous because relatively large forces can be cushioned with such devices with relatively small spring travel. With ring springs, however, it is not possible to build shock absorbers that only respond above a certain limit and then absorb the excessive shock and keep the energy that occurs during such shock away from the vehicle. It has therefore been proposed, for example in DE-PS 19 47 819, a device which is able to absorb oversized impacts. The disadvantage of this device, however, is that it can only respond to the coupling head with relatively large impacts and must be replaced by a new device after each response. This effort is considerable.

Weiter sind Elastikpatronen mit den unterschiedlichsten Federmedien bekannt. Am bekanntesten ist die Elastomer-Patrone, welche aus einem mit einem Kunststoff als Federmedium gefüllten Rohrkörper oder Zylinder besteht, wobei ein Kolben mit einem geringen Spalt zwischen Zylinderwand und Kolben in die Elastomermasse hineingedrückt werden kann, welche dann verdrängt wird und um den Kolben herumfliesst. Wird danach kein Druck mehr auf den Kolben ausgeübt, so fliesst das Elastomer infolge seiner besonderen Eigenschaften wieder in den Zylinder zurück, sodass nach einer gewissen Zeit die Elastomer-Patrone wieder in ihrem ursprünglichen Zustand mit herausstehender Kolbenstange vorliegt. Die Kraft, die notwendig ist, um den Kolben in die Kunststoffmasse hineinzudrücken, kann nun entweder durch Veränderung des Spaltes zwischen Zylinderwand und Kolben eingestellt werden oder durch Veränderung der Eigenschaften der Kunststoffmasse. Da darüberhinaus die Elastomermasse auch eine gewisse Elastizität besitzt, kann die Elastomer-Patrone auch z.B. anstelle von Ringfedern bei Mittelpufferkupplungen verwendet werden, was aber den Nachteil hat, dass die damit erzielbaren Federwege für die Praxis meist zu kurz sind.Elastic cartridges with a wide variety of spring media are also known. The best known is the elastomer cartridge, which consists of a tubular body or cylinder filled with a plastic as a spring medium, whereby a piston with a small gap between the cylinder wall and piston can be pressed into the elastomer mass, which is then displaced and flows around the piston. If there is no more pressure on the piston afterwards, the elastomer flows due to its special properties Properties back into the cylinder so that after a certain time the elastomer cartridge is back in its original condition with the piston rod sticking out. The force required to push the piston into the plastic mass can now be adjusted either by changing the gap between the cylinder wall and the piston or by changing the properties of the plastic mass. In addition, since the elastomer mass also has a certain elasticity, the elastomer cartridge can also be used, for example, instead of ring springs in central buffer couplings, but this has the disadvantage that the spring travel that can be achieved in this way is usually too short for practice.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde die Nachteile der bekannten Konstruktionen zu vermeiden und eine Kombination aus Ringfederelementen und Elastikpatronen bei Mittelpufferkupplungen zu verwenden, die die Vorteile beider Elemente ausnutzt, ohne deren Nachteile in Kauf nehmen zu müssen.The present invention is therefore based on the object of avoiding the disadvantages of the known constructions and of using a combination of ring spring elements and elastic cartridges in central buffer couplings, which takes advantage of the two elements without having to accept their disadvantages.

Die Lösung der Aufgabe besteht darin, dass eine mit dem Kuppelkopf verbundene Elastikpatrone drehfest aber längsverschieblich innerhalb einer in einem an der Anlenkung kardanisch angelenkten Gehäuse gelagerten Ringfeder liegt und dass ein Zwischenstück einen sich an das vordere Ende der Ringfeder anlegenden Anschlag und einen sich an die nach hinten herausgeführte Kolbenstange der Elastikpatrone anlegenden Anschlag besitzt, welcher sich ausserdem sowohl über eine hintere Zwischenlage gegen das hintere Ende der Ringfeder anlegt als auch einen der Einfederung der Ring- feder entsprechenden Abstand zum Endanschlag besitzt.The solution to the problem is that an elastic cartridge connected to the coupling head rests in a rotationally fixed but longitudinally displaceable manner within an annular spring mounted in a gimbal-mounted housing and that an intermediate piece attaches itself to the front end of the annular spring and one to the rear Piston rod of the elastic cartridge, which is led out at the rear, has a stop which also bears against the rear end of the ring spring via a rear intermediate layer and also has a distance from the end stop which corresponds to the deflection of the ring spring.

Vorteilhaft sind die Char kteristiken der Ringfeder und der Elastikpatrone unterschiedlich eingestellt, wobei vorzugsweise die Ansprechkraft der Elastikpatrone grösser ist als die grösste Federkraft der Ringfeder.The char kteristiken the ring spring and the elastic cartridge are advantageously set differently, preferably the response of the elastic cartridge is greater than the greatest spring force of the ring spring.

Zweckmässig besteht das Zwischenstück aus einem Rohrstück, auf dessen vorderes Ende der nach aussen überstehende Anschlag aufgeschraubt ist, welcher sich über eine vordere Zwischenlage gegen das vordere Ende der Ringfeder anlegt.The intermediate piece expediently consists of a tube piece, onto the front end of which the outwardly projecting stop is screwed, which abuts against the front end of the ring spring via a front intermediate layer.

Der Vorteil der erfindungsgemässen Vorrichtung liegt vor allem darin, dass die Elastikpatrone auch in dem Bereich, in dem die Ringfeder ihre Funktion erfüllt, schon einen elastischen Zwischenpuffer bildet, welcher erst dann, wenn der gesamte Weg der Ringfeder eingefedert ist, zur Wirkung kommt und dann immer noch übergrosse Stösse elastisch auffangen kann.The advantage of the device according to the invention lies above all in the fact that the elastic cartridge also forms an elastic intermediate buffer in the area in which the ring spring fulfills its function, which buffer takes effect only when the entire travel of the ring spring is compressed and then can still absorb oversized bumps elastically.

Nach der Zeichnung , in der eine beispielsweise Ausführungsform unter Verwendung einer Elastomer-Patrone dargestellt ist, ist das Gehäuse 11 für die Ringfeder 12 am (nicht dargestellten) Anlenkungsgehäuse kardanisch befestigt und wird durch an sich bekannte Szützbeine 13 in horizontaler Ebene auf Mitte gehalten, welche aber auch durch jede andere bekannte Vorrichtung zur Mittenstellung ersetzt werden kann. Innerhalb der Ringfeder 12 ist eine an sich bekannte Elastomer-Patrone 14 angeordnet, die am vorderen Ende mit dem (nicht dargestellten) Kuppelkopf verbunden ist. Zwischen Elastomer-Patrone 14 und Kuppelkopf kann aber auch:noch ein Verlängerungsstück vorgesehen werden. Zwischen Ringfeder 12 und Elastomer-Patrone 14 ist ein rohrförmiges Zwischenstück 15 vorgesehen, bei dem am vorderen Ende ein Anschlag 16 aufgeschraubt ist, welcher radial nach aussen über das Zwischenstück 16 übersteht und sich über die vordere Zwischenlame 17 am vorderen Ende der Ringfeder 12 anlegt. Gleitsteine aus Kunststoff mit kleinem Reibungskoeffizienten sind bei 18 zwischen Elastomer-Patrone 14 und Anschlag 16, bei 19 zwischen zwischen Anschlag 16 und Ringfedergehäuse 11 und bei 2o zwischen Ringfedergehäuse 11 und vorderer Zwischenlage 17 angeordnet, wodurch eine gute Verschiebbarkeit zwischen den drei Teilen relativ zueinander bewirkt wird.According to the drawing, in which an example embodiment is shown using an elastomer cartridge, the housing 11 for the ring spring 12 is gimbaled on the (not shown) articulation housing and is held in the horizontal plane at the center by known support legs 13, which but can also be replaced by any other known centering device. Arranged within the ring spring 12 is an elastomer cartridge 14 known per se, which is connected at the front end to the coupling head (not shown). An extension piece can also be provided between the elastomer cartridge 14 and the coupling head. Between the ring spring 12 and the elastomer cartridge 14, a tubular intermediate piece 15 is provided, in which a stop 16 is screwed on at the front end, which protrudes radially outward beyond the intermediate piece 16 and lies against the front intermediate lamella 17 at the front end of the ring spring 12. Plastic sliding blocks with a small coefficient of friction are at 18 between the elastomer cartridge 14 and the stop 16, at 19 between arranged between the stop 16 and the ring spring housing 11 and at 20 between the ring spring housing 11 and the front intermediate layer 17, as a result of which good displacement between the three parts is effected relative to one another.

Eine Verdrehung der einzelnen Teile zueinander wird dadurch verhindert, dass einerseits am Ringfedergehäuse 11 ein Keil 22 mit der Schraube 23 befestigt ist, welcher in einer Nut 21 im Anschlag 16 längsverschieblich gelagert ist. Damit wird eine Verdrehung des Zwischenstücks 15 gegenüber dem Gehäuse 11 verhindert. Andererseits trägt die Elastomer-Patrone 14 einen Keil 24, welcher in einem Längsschlitz 25 im Zwischenstück 15 verschiebbar ist. Dadurch wird eine Verdrehung von Elastomer-Patrone 14 relativ zum Zwischenstück 15 verhindert. Beide Massnahmen zusammen verhindern also, dass sich der an der Elastomer-Patrone 14 befestigte Kuppelkopf gegenüber der Anlenkung verdrehen kann.Rotation of the individual parts relative to one another is prevented in that, on the one hand, a wedge 22 is fastened to the ring spring housing 11 with the screw 23 and is mounted in a groove 21 in the stop 16 so as to be longitudinally displaceable. This prevents the intermediate piece 15 from rotating relative to the housing 11. On the other hand, the elastomer cartridge 14 carries a wedge 24 which is displaceable in a longitudinal slot 25 in the intermediate piece 15. This prevents the elastomer cartridge 14 from rotating relative to the intermediate piece 15. Both measures together prevent the coupling head attached to the elastomer cartridge 14 from rotating relative to the articulation.

Am rückwärtigen Ende des Zwischenstücks 15 ist ein Anschlag 26 soweit eingeschraubt, dass sich der Anschlag 26 gegen die nach hinten harausragende Kolbenstange 27 der Elastomer-Patrone 14 anlegt und mit dem Bund 34 eine Vorspannung erzeugt, wobei zur besseren Führung die Kolbenstange 27 in eine Ausnehmung 28 im Anschlag 26 eingreift. Ein nach aussen über das Zwischenstück vorstehender Bund oder Flansch 29 legt sich von hinten her über die hintere Zwischenlage 3o gegen die Ringfeder 12 an. Der Bund 29 kann auch Teil des Anschlags 26 sein. Die Zwischenlage 30 ist nach hinten soweit verlängert, dass sie am Endanschlag 31 anliegt und dadurch das Widerlager für die Ringfeder 12 bildet. Zwischen dem Endanschlag 31 und dem Anschlag 26 ist in Normallage ein Abstand R, welcher dem zulässigen Einfederungsweg der Ringfeder 12 entspricht. Zwischen der hinteren Zwischenlage 3o und dem Gehäuse 11 einerseits und dem Flansch 29 andererseits sind Gleitstücke 32 und 33 aus einem reibungsarmen Kunststoff angeordnet.At the rear end of the intermediate piece 15, a stop 26 is screwed in so far that the stop 26 bears against the piston rod 27 of the elastomer cartridge 14 projecting towards the rear and generates a prestress with the collar 34, the piston rod 27 being better guided in a recess 28 engages in the stop 26. A collar or flange 29 projecting outward beyond the intermediate piece lies against the annular spring 12 from behind via the rear intermediate layer 3o. The collar 29 can also be part of the stop 26. The intermediate layer 3 0 is extended to the rear so far that it abuts the end stop 31 and thereby forms the abutment for the ring spring 12. In the normal position, there is a distance R between the end stop 31 and the stop 26, which corresponds to the permissible deflection path of the ring spring 12. Between the rear intermediate layer 3o and the housing 11 on the one hand and the flange 29 on the other are sliders 32 and 33 arranged from a low-friction plastic.

Die im normalen Verkehr auftretenden Stösse werden vom Kuppelkopf auf die Elastomer-Patrone 14 übertragen, welche ihrerseits die Stösse über die Kolbenstange 27, den Anschlag 26, das Zwischenstück 15, densAnschlag 16 und die Zwischenlage 17 aufdie Ringfeder 12 überträgt, welche dann einfedert. Übersteigt bei einem zu grossen Stoss die Stosskraft die Kraft der Ringfeder 12, so wird der Anschlag 26 soweit zurückgeschoben, dass er am Endanschlag 31 anliegt, also den Weg R durchlaufen hat. Wird jetzt infolge des übergrossen Stosses noch weiter über den Kuppelkopf auf die Elastomer-Patrone 14 gedrückt, so verschiebt sich die Patrone 14 um höchstens den Weg E,wobei die Kolbenstange 27 in die Patrone 14 hineingeschoben wird und dort in bekannter Weise den Kunststoff verdrängt. Dabei wird die Stossenergie vernichtet. Voraussetzung dafür ist allerdings, dass die Ansprechkraft der Elastomer-Patrone 14 grösser ist als die grösste von der Ringfeder 12 aufzubringende Kraft. Während des Eindringens der Kolbenstange 27 wird die Stossenergie vernichtet. Diese Stossenergie wird also von der Anlenkung und damit vom Fahrzeug ferngehalten. Hört der Stoss auf, so verschiebt sich die Elastomer-Patrone 14 infolge der bekannten Eigenschaften des Elastomers wieder innerhalb des Zwischenstücks:15 um den Weg E nach vorne, bis der in der Zeichnung dargestellte Zustand wieder erreicht ist. Da die Ansprechkraft der Elastomer-Patrone.14 stark von der Auflaufgeschwindigkeit abhängig ist, kann es möglich sein, dass während der axialen Bewegung des Kuppelkopfs eine Überlagerung der Hübe der Ringfeder 12 sowie der Elastomer-Patrone 14 stattfindet.The shocks occurring in normal traffic is transferred from the coupling head to the elastomeric cartridge 14 which, which then compresses turn the bumps on the piston rod 27, the stop 26, the intermediate piece 15, the s stop 16 and the intermediate sheet 17 aufdie annular spring 12 transmits . If the impact force exceeds the force of the ring spring 12 in the event of an excessive impact, the stop 26 is pushed back so far that it abuts the end stop 31, that is to say has passed the path R. If, as a result of the oversized impact, the elastomer cartridge 14 is pressed even further over the coupling head, the cartridge 14 moves by at most path E, the piston rod 27 being pushed into the cartridge 14 and displacing the plastic there in a known manner. The impact energy is destroyed. The prerequisite for this, however, is that the response force of the elastomer cartridge 14 is greater than the greatest force to be exerted by the ring spring 12. The impact energy is destroyed during the penetration of the piston rod 27. This impact energy is therefore kept away from the linkage and thus from the vehicle. If the impact ceases, the elastomer cartridge 14 moves again within the intermediate piece: 15 by the path E due to the known properties of the elastomer, until the state shown in the drawing is reached again. Since the response force of the elastomer cartridge 14 is strongly dependent on the run-up speed, it may be possible that the strokes of the ring spring 12 and the elastomer cartridge 14 overlap during the axial movement of the coupling head.

Bei Zug am Kuppelkopf wird die Elastomer-Patrone 14 nach vorn gezogen. Dann wird die Zugkraft über den Bund 34, das Zwischenstück 15, den Flansch 29 und die hintere Zwischenlage 3o auf die Ringfeder 12 übertragen, welche sich gegen den Bund 35 anlegt und einfedert. Die Elastomer-Patrone 14 wird bei Zug am Kuppelkopf nicht in Anspruch genommen.When pulling on the coupling head, the elastomer cartridge 14 is pulled forward. Then the tensile force is transmitted via the collar 34, the intermediate piece 15, the flange 29 and the rear intermediate layer 3o to the ring spring 12, which bears against the federal government 35 and compresses. The elastomer cartridge 14 is not used when pulling on the coupling head.

Selbstverständlich lässt sich die Anordnung auch bei gleicher Wirkungsweise umkehren, sodass der Kuppelkopf am Ringfedergehäuse 11 angeordnet ist und die Vorrichtung mit der Elastomer-Patrone 14 am Fahrzeug direkt oder über ein Anlenkgehäuse angelenkt ist.Of course, the arrangement can also be reversed with the same mode of operation, so that the coupling head is arranged on the ring spring housing 11 and the device with the elastomer cartridge 14 is articulated directly on the vehicle or via a link housing.

Die Anschläge 16 und 26 sind in an sich bekannter Weise gegen Verdrehen auf dem Zwischenstück 15 gesichert. Es können auch alle an sich bekannten Mittenrückstellvorrichtungen verwendet werden.The stops 16 and 26 are secured against rotation on the intermediate piece 15 in a manner known per se. All center reset devices known per se can also be used.

Das Federmedium in der Elastikpatrone kann ein Elastomer, ein vorgespanntes Gas, ein mit einem Speicher verbundenes Fluid oder auch eine oder mehrere Ring- oder Schraubenfedern, geteilt oder ungeteilt, sein.The spring medium in the elastic cartridge can be an elastomer, a prestressed gas, a fluid connected to a storage device or one or more ring or coil springs, divided or undivided.
