Definitions
- the invention relates to a support and centering device with an elastomer element, which is arranged between and connected to two parallel plates for the elastic support and resetting of a coupling rod of a central buffer coupling for track-guided land vehicles, the coupling rod on the vehicle side horizontally about a vertical axis and about a horizontal axis vertically limited pivotally attached.
- the prestressed elastomer element (rubber body) is supported with its end faces between two horizontal plates and carried by a two-armed handlebar.
- the plates, and thus the elastomer element are guided such that they can be adjusted in height in arms which are articulated in a pendulum manner on the handlebars such that when the coupling head moves vertically, the axis of the elastomer element adjusts itself perpendicular to the coupling head axis.
- the central buffer coupling is spring-supported and is held horizontally.
- the support can follow horizontal pivoting movements of the dome head as well as vertical deflections to compensate for height differences between two dome heads to be coupled without undue tension.
- the invention is therefore based on the object to provide a technically simple device for supporting and resetting both in the vertical and in the horizontal plane, which can be used in a compact design and with a small height, even in narrow installation spaces on track-guided land vehicles.
- a supporting and centering device 1 has an elastomer element 2 which is arranged between a first plate 3a and a second plate 3b and is connected to these.
- the elastomer element 2 is arranged or aligned in the direction of the dome axis and in the vertical dome plane, with which the plates 3a, 3b enclosing the elastomer element 2 on both end faces are oriented vertically and in the central position transversely to the longitudinal direction of the vehicle.
- the first plate 3a is fixed in a rotationally fixed manner to a bolt 4 arranged in the vertical pivot axis.
- the bolt 4 is connected in a rotationally fixed manner to a bearing block 6 fixed to the vehicle by means of a rotation lock 5.
- the second plate 3b arranged closer to the coupling head is connected to the coupling rod 8 via a releasable fastening 7.
- the elastomer element 2 is expediently arranged below the coupling rod 8, since the coupling rod 8 can then be arranged higher. In this arrangement, the elastomer element 2 is also largely relieved of tensile stresses.
- the elastomeric element 2 must be suitable for safely returning the operationally required pivoting angles in the vertical direction of approximately +/- 6 ° and in the horizontal direction of approximately +/- 15 ° to the central position over longer periods of time.
- the Shore hardness for suitable elastomer elements is around 50 to 80 Shore.
- the elastomer element 2 is formed from the second plate 3b in the direction of the first plate 3a with a decreasing cross-sectional area and z.
- B the shape of a cone or pyramid.
- the elastomer element 2 can be formed on the end faces with a rectangular or square base surface.
- the elastomer element 2 is advantageously arranged with the short sides of the base surfaces in the vertical and with the long sides in the horizontal.
Description
Die Erfindung betrifft eine Abstütz- und Mittenstelleinrichtung mit Elastomerelement, das zwischen zwei parallelen Platten angeordnet und mit diesen verbunden ist, zum elastischen Abstützen und Rückstellen einer Kuppelstange einer Mittelpufferkupplung für spurgeführte Landfahrzeuge, wobei die Kuppelstange fahrzeugseitig um eine vertikale Achse horizontal und um eine horizontale Achse vertikal begrenzt schwenkbar befestigt ist.The invention relates to a support and centering device with an elastomer element, which is arranged between and connected to two parallel plates for the elastic support and resetting of a coupling rod of a central buffer coupling for track-guided land vehicles, the coupling rod on the vehicle side horizontally about a vertical axis and about a horizontal axis vertically limited pivotally attached.
Bei einer derartigen aus der DE-PS 10 17 201 bekannten Abstütz- und Mittenstelleinrichtung mit Elastomerelement ist das vorgespannte Elastomerelement (Gummikörper) mit seinen Stirnflächen zwischen zwei waagerechten Platten abgestützt und von einem zweiarmigen Lenker getragen. Die Platten, und damit das Elastomerelement, sind in pendelnd am Lenker angelenkten Armen höhenverstellbar derart geführt, daß bei lotrechter Bewegung des Kuppelkopfes die Achse des Elastomerelementes sich senkrecht zur Kuppelkopfachse einstellt. Durch diese Anordnung ist die Mittelpufferkupplung federnd abgestützt und wird in der Horizontalen gehalten. Gleichzeitig kann die Abstützung ohne unzulässige Verspannungen horizontalen Schwenkbewegungen des Kuppelkofes sowie vertikalen Auslenkungen zum Ausgleich von Höhendifferenzen zwischen zwei zu kuppelnden Kuppelköpfen folgen.In such a support and centering device known from DE-PS 10 17 201 with an elastomer element, the prestressed elastomer element (rubber body) is supported with its end faces between two horizontal plates and carried by a two-armed handlebar. The plates, and thus the elastomer element, are guided such that they can be adjusted in height in arms which are articulated in a pendulum manner on the handlebars such that when the coupling head moves vertically, the axis of the elastomer element adjusts itself perpendicular to the coupling head axis. With this arrangement, the central buffer coupling is spring-supported and is held horizontally. At the same time, the support can follow horizontal pivoting movements of the dome head as well as vertical deflections to compensate for height differences between two dome heads to be coupled without undue tension.
Diese Anordnung ermöglicht allerdings nur eine Abstützung und Mittenstellung der Kuppelstange in vertikaler Richtung.However, this arrangement only allows the coupling rod to be supported and positioned in the vertical direction.
Um ein einwandfreies Kuppeln zweier Mittelpufferkupplungen zu ermöglichen, ist es aber außerdem notwendig, die Kuppelstange beim Kuppelvorgang stets in Mittenlage in der Mittellängsebene zu halten, d. h. eine Mittenrückstellung bei Auslenkungen in der Horizontalebene zu gewährleisten.In order to enable a perfect coupling of two center buffer clutches, it is also necessary to always keep the coupling rod in the center position in the central longitudinal plane during the coupling process, ie to ensure a central reset in the event of deflections in the horizontal plane.
Zu diesem Zweck sind eine große Anzahl von Rückstellsystemen bekannt, die z. B. hydraulisch oder durch Federkraft die Einstellung der Mittenlage in der Horizontalebene ermöglichen.For this purpose, a large number of reset systems are known, for. B. hydraulically or by spring force to adjust the center position in the horizontal plane.
Da an den Stirnseiten der spurgeführten Landfahrzeuge für die Mittelpufferkupplungen wenig Einbauraum zur Verfügung steht, ist es oft schwierig und technisch aufwendig, eine Abstützeinrichtung und eine Mittenstelleinrichtung im zur Verfügung stehenden Einbauraum vorzusehen.Since there is little installation space available on the front sides of the track-guided land vehicles for the central buffer clutches, it is often difficult and technically complex to provide a support device and a centering device in the available installation space.
Der Erfindung liegt daher die Aufgabe zugrunde, eine technisch einfache Einrichtung zur Abstützung und Mittenrückstellung sowohl in vertikaler als auch in horizontaler Ebene zu schaffen, die bei kompakter Bauweise und bei geringer Höhenabmessung auch in eng bemessenen Einbauräumen an spurgeführten Landfahrzeugen verwendet werden kann.The invention is therefore based on the object to provide a technically simple device for supporting and resetting both in the vertical and in the horizontal plane, which can be used in a compact design and with a small height, even in narrow installation spaces on track-guided land vehicles.
Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Abstütz- und Mittenstelleinrichtung gelöst.This object is achieved by the supporting and centering device characterized in claim 1.
