Description

Die Erfindung betrifft eine extrem kurze Hochleistungs-Zugstange für Mittelkupplungen bzw. Mittelpufferkupplungen, insbesondere für Schienenfahrzeuge, bestehend aus einem hydroelastischen Element, wie zum Beispiel eine "Oleopatrone", an deren vorderem Ende der Kuppelkopf mit einer Schalenmuffe o.ä. befestigt ist, und einer auf Zugkräfte am Kuppelkopf ansprechenden Reibungsfeder, wobei das rückwärtige Ende der Zugstange mit einem Anlenkbolzen an der am Fahrzeug angebrachten Anlenkung befestigt ist.The invention relates to an extremely short high-performance tie rod for center couplings or center buffer couplings, in particular for rail vehicles, consisting of a hydroelastic element, such as an "oleopatrone", at the front end of which the coupling head with a shell sleeve or the like. is attached, and a friction spring responsive to tensile forces on the coupling head, the rear end of the tie rod being attached to the linkage attached to the vehicle by means of a link pin.

Es ist bekannt (DE 34 16 749 A1 ) Reibungsfedern und hydroela­stische Elemente wie "Oleopatrone" o.ä. miteinander zu kombinie­ren, um die Vorteile der beiden Elemente zu erhalten, ohne jedoch deren Nachteile in Kauf nehmen zu müssen. Der wesentliche Nachteil dieser bekannten Vorrichtungen besteht vor allem darin. dass die Baulänge solcher Zugstangen relativ gross ist, was wie­derum zu einem grösseren Abstand der miteinander verkuppelten Fahrzeuge führt. Rein theoretisch könnte man zwar den Anlenkpunkt der so gestalteten Zugstange weiter unter das Fahrzeug verlegen, aber damit wären wieder andere zum Teil sehr schwerwiegende Nachteile verbunden, wie zum Beispiel der grosse Raumbedarf einer solchen Anlenkung mit Zugstange.It is known (DE 34 16 749 A1) friction springs and hydroelastic elements such as "oleopatrone" or the like. to combine with each other in order to obtain the advantages of the two elements without having to accept their disadvantages. The main disadvantage of these known devices is primarily that. that the overall length of such tie rods is relatively large, which in turn leads to a greater distance between the vehicles coupled together. Theoretically, the articulation point of the drawbar designed in this way could be moved further under the vehicle, but this would involve other, in some cases very serious, disadvantages, such as the large space requirement of such a drawbar connection.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde eine Zugstange zu schaffen, welche relativ sehr kurz ist und trotz­dem alle Vorteile der Kombination von Reibungsfeder und Oleo­patrone besitzt. Man strebte sogar an, in diese extrem kurz­ bauende Zugstange auch noch ein an sich bekanntes mechanisches Stossverzehrglied (DE 19 47 819 C3 ) zu integrieren.The object of the present invention is therefore to create a pull rod which is relatively very short and yet has all the advantages of the combination of a friction spring and an oleopatrone. One even aimed at being extremely short constructing tie rod also integrate a known mechanical shock absorbing member (DE 19 47 819 C3).

Die Lösung dieser Aufgabe besteht darin, dass auf dem Gehäuse der Oleopatrone ein Deckellager drehfest aber längsverschieblich gelagert ist, und eine kurze Reibungsfeder sich einerseits am Deckellager und andererseits über ein Zwischenrohr am Kragen der Oleopatrone abstützt und auf dem Zwischenrohr das Verformungs­rohr des Stossverzehrgliedes liegt, welches sich nach vorn an einem Anschlagflansch des Zwischenrohrs abstützt und nach hinten mit dem am Anlenkteller abgestützten Druckrohr des Stossverzehr­gliedes zusammenwirkt und die Zugstange durch mindestens drei das Deckellager mit dem Druckrohr verspannende Zuganker zusammen­gehalten wird.The solution to this problem is that a cover bearing is mounted on the housing of the oleopatrone in a rotationally fixed but longitudinally displaceable manner, and a short friction spring is supported on the one hand on the cover bearing and on the other hand via an intermediate tube on the collar of the oleopatrone and the deformation tube of the shock absorbing member, which lies on the intermediate tube is supported at the front on a stop flange of the intermediate tube and cooperates at the rear with the pressure tube of the shock absorbing member supported on the link plate and the tie rod is held together by at least three tie rods that clamp the cover bearing with the pressure tube.

Vorteilhaft ist das Druckrohr des Stossverzehrgliedes mit einem Anlenkteller am Anlenkbolzen des Anlenkgehäuses angelenkt.The pressure tube of the shock absorbing member is advantageously articulated with a link plate on the link pin of the link housing.

Zweckmässig stützt sich der aus der Oleopatrone heraustretende Kolben an einer Anschlagplatte ab, welche sich ihrerseits an einem Bund im Verformungsrohr abstützt.The piston emerging from the oleo cartridge is expediently supported on a stop plate, which in turn is supported on a collar in the deformation tube.

Der Vorteil der erfindungsgemässen Vorrichtung besteht vor allem darin, dass die Zugstange einerseits sehr kurz ist und andererseits sehr grosse Kräfte übertragen kann, wobei aber die zu starken Druck oder Stosskräfte auf den Kuppelkopf wirksam aufgefangen und vom Fahrzeug selbst durch ein Stossverzehrglied abgehalten werden können.The advantage of the device according to the invention is above all that the pull rod is on the one hand very short and on the other hand can transmit very large forces, but the excessive pressure or impact forces on the coupling head can be effectively absorbed and prevented by the vehicle itself by means of a shock absorbing member.

In den Zeichnungen ist eine beispielsweise Ausführungsform der Erfindung dargestellt und zwar zeigt :

  • Figur 1 eine Seitenansicht der Zugstange
  • Figur 2 einen Horizontalhalbschnitt der Vorrichtung nach Fig. 1.
An exemplary embodiment of the invention is shown in the drawings and shows:
  • Figure 1 is a side view of the tie rod
  • FIG. 2 shows a horizontal half section of the device according to FIG. 1.

Nach Fig. 1 ist die Zugstange mit einem Anlenkteller 11 auf dem Anlenkbolzen 12 kardanisch gelagert, wobei der Bolzen 12 im am Fahrzeug befestigten Anlenkgehäuse 13 gelagert ist. Der Anlenkteller 11 trägt einen viereckigen Flansch 14, welcher mit dem auf der Oleopatrone 16 liegenden ebenfalls viereckigen Deckellager 15 korrespondiert. In jeder Ecke des Deckellagers 15 und des Flansches 14 ist ein diese beiden Teile verspannender Zuganker 17 angeordnet, welcher mit Muttern 18 so zusammenge­zogen werden, dass die Zugstange eine Einheit bildet. Das Gehäuse der Oleopatrone 16 ist nach vorn herausgeführt und trägt dort eine Schalenmuffe 19, mit der der (nicht dargestellte ) Kuppelkopf an der Zugstange befestigt ist.1, the tie rod is gimbal-mounted with a link plate 11 on the link pin 12, the pin 12 being mounted in the linkage housing 13 attached to the vehicle. The articulation plate 11 carries a square flange 14, which corresponds to the cover bearing 15, which is also square and lies on the ole cartridge 16. In each corner of the cover bearing 15 and the flange 14 there is a tie rod 17 which braces these two parts and which is pulled together with nuts 18 in such a way that the tie rod forms a unit. The housing of the oleo cartridge 16 is led out to the front and there carries a shell sleeve 19 with which the coupling head (not shown) is fastened to the pull rod.

Nach Fig. 2 besteht die Zugstange aus einer Oleopatrone 16, auf deren Vorderseite ein Deckellager 15 drehfest aber längsver­schieblich gelagert ist. Hinter dem Deckellager 15 ist eine kurze Reibungsfeder 20 angeordnet, welche sich einerseits am Deckellager 15 und andererseits am Zwischenrohr 21 abstützt. Das Zwischenrohr 21 stützt sich mit dem inneren Flansch 22 bei Zug an der Vorrichtung auf dem Kragen 23 der Oleopatrone 16 ab. Am hinteren Ende des Verformungsrohrs 26 ist ein Bund vorgesehen, gegen den sich der aus der Oleopatrone 16 nach hinten heraustretende Kolben 25 über die Anschlagplatte 24 anlegt. Der Abstand zwischen dem Kragen 23 der Oleopatrone 16 und der Anschlagplatte 24 gibt den Hub, den die Oleopatrone bei Druck auf den Kuppelkopf machen kann. Auf dem Zwischenrohr 21 ist ein Stützrohr 28 gelagert. Das Verformungsrohr 26 stützt sich nach vorn mit dem Zwischenrohr bzw. Stützrohr 28 am Deckel­lager 15 ab und am hinteren Ende ist die konische Druckfläche 29 mit Abscherring angeordnet, die mit der entsprechenden Druck­fläche 29 am Druckrohr 27 das Stossverzehrglied bildet.According to Fig. 2, the pull rod consists of an oleo cartridge 16, on the front of which a cover bearing 15 is rotatably but longitudinally displaceably mounted. A short friction spring 20 is arranged behind the cover bearing 15, which is supported on the one hand on the cover bearing 15 and on the other hand on the intermediate tube 21. The intermediate tube 21 is supported with the inner flange 22 when the device is pulled on the collar 23 of the ole cartridge 16. A collar is provided at the rear end of the deformation tube 26, against which the piston 25 emerging from the ole cartridge 16 bears against the stop plate 24. The distance between the collar 23 of the oleo cartridge 16 and the stop plate 24 gives the stroke that the oleo cartridge can make when pressure is exerted on the coupling head. A support tube 28 is mounted on the intermediate tube 21. The deformation tube 26 is supported forward with the intermediate tube or support tube 28 on the cover bearing 15 and at the rear end the conical pressure surface 29 is arranged with a shear ring, which forms the shock absorbing member with the corresponding pressure surface 29 on the pressure tube 27.

Bei der Benutzung dieser Zugstange wird bei Druck auf den Kuppe­ kopf die Oleopatrone 16 gegen die Kraft des Kolbens 25 in Richtung auf die Anschlagplatte 24 verschoben, wodurch die Stossenergie verbraucht wird. Wenn die Energie aber noch nicht verbraucht ist, obwohl die Patrone 16 an der Anschlagplatte 24 anliegt (Über­lastfall), so wird das Zwischenrohr 21 mit dem Kragen 30 das Verformungsrohres 26 in das Druckrohr 27 hineintreiben und dieses unter Energieverlust aufweiten, indem die konischen Flächen 29 der beiden Rohre aufeinandergleiten. Der Hub des Stossverzehr­gliedes kann je nach Bedarf festgelegt werden. Beim Ansprechen des Verformungsrohres 26 gleitet das Deckellager 15 ebenfall über den Hub des Stossverzehrgliedes nach hinten. Darin liegt ein Vorteil der erfindungsgemässen Anordnung, bezogen auf die Baulänge. Der Stossverzehrhub wird im Bereich vor dem Deckel­lager 15 (Faltenbalg) nicht berücksichtigt, was die Baulägenein­sparung ergibt.When using this pull rod, the top is pressed head the oleo cartridge 16 against the force of the piston 25 in the direction of the stop plate 24, whereby the impact energy is consumed. If, however, the energy has not yet been consumed, even though the cartridge 16 is in contact with the stop plate 24 (overload), the intermediate tube 21 with the collar 30 will drive the deformation tube 26 into the pressure tube 27 and expand it with loss of energy by the conical surfaces 29 of the two pipes slide together. The stroke of the shock absorbing member can be determined as required. When the deformation tube 26 responds, the cover bearing 15 also slides back over the stroke of the shock absorbing member. This is an advantage of the arrangement according to the invention, based on the overall length. The shock absorption stroke is not taken into account in the area in front of the cover bearing 15 (bellows), which results in the saving in constructional length.

Bei Zug am Kuppelkopf nimmt die Oleopatrone 16 über den Kragen 23, welcher sich hinter den Flansch 22 legt, das Zwischenrohr 21 mit. Der Kragen 30 des Zwischenrohrs 21 ist gegen die Reibungs­feder 20 angelegt, welche sich ihrerseits an Deckellager 15 abstützt. Vom Deckellager 15 wird die Zugkraft über die Zuganker 17 bis zum Anlenkteller 11 weitergeleitet und von da über die Anlenkung 12,13 bis in das Fahrzeug geführt. Der Hub der Reibungs­feder 20 kann je nach Bedarf festgelegt werden. Hören die Kräfte auf, so wird einerseits der Kolben 25 wieder aus der Oleo­patrone 16 herausgedrückt, bis er die in Fig. 2 dargestellte Lage einnimmt und andererseits entspannt sich die Reibungsfeder 20, bis sie ebenfalls wieder die in Fig. 2 dargestellte Ausgangs­lage einnimmt.When pulling on the coupling head, the oleo cartridge 16 takes the intermediate tube 21 over the collar 23, which lies behind the flange 22. The collar 30 of the intermediate tube 21 is placed against the friction spring 20, which in turn is supported on the cover bearing 15. The tensile force is transmitted from the cover bearing 15 via the tie rods 17 to the articulation plate 11 and from there via the articulation 12, 13 into the vehicle. The stroke of the friction spring 20 can be determined as required. If the forces cease, on the one hand the piston 25 is pressed out of the ole cartridge 16 again until it assumes the position shown in FIG. 2, and on the other hand the friction spring 20 relaxes until it again assumes the starting position shown in FIG. 2.
