Description

  

      Puffer,        insbesondere        für        Schienenfahrzeuge            Schienenfahrzeuge    werden mit Puffern versehen,  um hauptsächlich während des     Rangierens    auftre  tende Stösse aufzunehmen. Um unangenehme Stösse  während der Fahrt zu     vermeiden,    werden die einzel  nen     Schienenfahrzeuge    so miteinander verbunden,  dass sich die in den Puffern befindlichen Federele  mente stets unter einer Vorspannung befinden.

   Durch  die ungleichen     Schwankungen    der Fahrzeuge während  der Fahrt führen die aneinander anliegenden     Puffer-          teller    relative Bewegungen aus. Demzufolge verursa  chen die auf die Puffer wirkenden Kräfte eine ver  hältnismässig rasche Abnützung der aus Stahl her  gestellten Pufferteller, was zu einem häufigen Ersatz  derselben zwingt. Ein weiterer Nachteil der aus Stahl  hergestellten Pufferteller besteht darin, dass sie beim  Aufeinanderstossen, insbesondere beim Rangieren,  einen grossen Lärm     verursachen.     



  Bei dem den     Gegenstand    vorliegender     Erfindung     bildenden     Puffer,        insbesondere    für     Schienenfahrzeuge,     soll dieser     Nachteil    dadurch vermieden sein, dass der  Pufferteller ganz oder     teilweise    aus einem     Kunststoff     hergestellt ist. Aus     Festigkeitsgründen    wird dabei vor  teilhaft nur der innere Teil des Tellers aus     Kunststoff          ausgeführt,    während der äussere Teil des     Puffertellers     aus Stahl hergestellt wird.

      Die     einzige    Figur     derbeiliegenden        Zeichnung    ver  anschaulicht ein     Beispiel    eines erfindungsgemässen       Puffers    im     Schnitt.    Am     Pufferstössel    1 ist     ein.    äusserer       Teil    2 in Form eines Stahlringes mit     Hilfe    von Nieten  3     befestigt.    Dieser     äussere        Teil    2 weist     eineinRichtung     des Stössels 1 erweiterte konische Bohrung 4 auf,  welche die Aufgabe hat,

   einen mit     einem    konischen  Rand versehenen inneren Teil 5 aus einem Kunst  stoff, beispielsweise aus Nylon,     festzuhalten.     



  In der Figur ist als Beispiel ein     bombierter        Teller     gezeigt. Der gezeigte Kunststoffteil lässt sich aber  auch an flachen Tellern anbringen.  



  Selbstverständlich     kann,    bei     Weglassung    des Stahl  ringes 2, der ganze     Pufferteller    aus     Kunststoff    be  stehen.



      Buffers, especially for rail vehicles Rail vehicles are provided with buffers in order to absorb impacts occurring mainly during maneuvering. In order to avoid unpleasant bumps while driving, the individual rail vehicles are connected to one another in such a way that the spring elements in the buffers are always pretensioned.

   Due to the unequal fluctuations of the vehicles during the journey, the adjacent buffer plates perform relative movements. As a result, the forces acting on the buffers cause a relatively rapid wear and tear of the buffer plates made of steel, which forces them to be replaced frequently. Another disadvantage of the buffer plates made of steel is that they cause a lot of noise when they collide, especially when maneuvering.



  In the case of the buffer forming the subject of the present invention, in particular for rail vehicles, this disadvantage is to be avoided in that the buffer plate is made entirely or partially from a plastic. For reasons of strength, only the inner part of the plate is made of plastic, while the outer part of the buffer plate is made of steel.

      The single figure of the accompanying drawing illustrates an example of a buffer according to the invention in section. There is a on buffer tappet 1. outer part 2 in the form of a steel ring with the help of rivets 3 attached. This outer part 2 has a conical bore 4 widened in the direction of the plunger 1, which has the task of

   a conical edge provided with an inner part 5 made of a plastic, such as nylon to hold.



  In the figure, a cambered plate is shown as an example. The plastic part shown can also be attached to flat plates.



  Of course, if the steel ring 2 is omitted, the entire buffer plate be made of plastic.
