Description

Die Erfindung betrifft einen Hülsenpuffer für Schienenfahrzeuge, im wesentlichen gebildet aus einem Pufferstößel mit Pufferteller, einer Pufferhülse mit fahrzeugseitig anschraubbarer Grundplatte sowie einer Feder.The invention relates to a sleeve buffer for rail vehicles, essentially formed from a buffer tappet with a buffer plate, a buffer sleeve with a base plate that can be screwed on the vehicle side, and a spring.

Durch den Katalog R 57 der Ringfeder GmbH vom 24.02.87 sind Hülsenpuffer mit den vorgenannten Merkmalen bekannt. Wie diesem Katalog weiter zu entnehmen ist, stehen zwei Ausführungen von Puffergehäusen zur Verfügung: Bei dem sogenannten Standard-Puffergehäuse sind der Pufferstößel mit Pufferteller und die Pufferhülse mit Grundplatte jeweils einteilig, wobei am Pufferstößel ein Haltering angeschweißt ist, der in Ausschubrichtung des Hülsenpuffers mit einem Bund der Pufferhülse formschlüssig zusammenwirkt. Bei dem anderen Puffergehäuse sind der Pufferstößel und der Pufferteller separate Teile und durch Schrauben miteinander verbunden. In dieser Bauform dienen zwei zwischen Pufferstößel und Pufferhülse angeordnete Halbschalen der Ausschubbegrenzung. Als Pufferfedern können beispielsweise eine Reibungsfeder oder eine Hydraulikkapsel eingesetzt werden. Für erhöhte Beanspruchungen des Puffertellers, bedingt durch die Wagenbauart oder ungünstige Betriebsbedingungen, wird empfohlen, in den Pufferteller zur Verschleißminderung eine Platte aus Hartmanganstahl einzuschweißen. Diese Platte und deren Befestigung bedeuten jedoch einen vergrößerten Aufwand mit entsprechendem Preis. Im übrigen hat sich in der Praxis gezeigt, daß auch mit Platten aus Hartmanganstahl bestückte Hülsenpuffer Verschleißerscheinungen aufweisen, und zwar vor allem bei größeren, in engen Gleisbögen auftretenden Reibbewegungen anliegender Pufferteller.Through the catalog R 57 of the Ringfeder GmbH from February 24th, 1987, sleeve buffers with the aforementioned features are known. As can be seen from this catalog, there are two versions of buffer housings available: In the so-called standard buffer housing, the buffer tappet with buffer plate and the buffer sleeve with base plate are each in one piece, with a retaining ring welded to the buffer tappet, which is attached in the direction of extension of the sleeve buffer The collar of the buffer sleeve interacts positively. In the other buffer housing, the buffer tappet and the buffer plate are separate parts and are connected by screws. In this design, two half-shells arranged between the buffer tappet and the buffer sleeve serve to limit the extension. For example, a friction spring or a hydraulic capsule can be used as buffer springs. For increased loads on the buffer plate due to the car design or unfavorable operating conditions, it is recommended to weld a plate made of manganese steel into the buffer plate to reduce wear. However, this plate and its attachment mean an increased effort with a corresponding price. Moreover, it has been shown in practice that sleeve buffers equipped with plates made of hard manganese steel show signs of wear, namely before especially in the case of larger buffing plates in the case of larger rubbing movements occurring in narrow curves.

Der Erfindung liegt die Aufgabe zugrunde, einen Hülsenpuffer der gattungsgemäßen Art auf möglichst einfache und kostengünstige Weise derart auszubilden, daß insbesondere eine hohe Widerstandsfähigkeit gegenüber Verschleiß erzielbar ist.The invention has for its object to form a sleeve buffer of the generic type in a simple and inexpensive manner such that in particular a high resistance to wear can be achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Pufferteller aus einem oberflächenhärtbaren Werkstoff besteht und nach der Oberflächenhärtung eine Härte von mindestens 350 HV 30 bei Rht 250 >= 3 mm aufweist.This object is achieved according to the invention in that the buffer plate consists of a surface-hardenable material and, after surface hardening, has a hardness of at least 350 HV 30 at Rht 250> = 3 mm.

Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous further developments of the subject matter of the invention can be found in the subclaims.

Im weiteren wird die Erfindung anhand von Ausführungsbeispielen näher beschrieben, die in der Zeichnung dargestellt sind. Die Fig. 1 und 2 zeigen jeweils einen Hülsenpuffer im Längsschnitt.The invention is described in more detail below on the basis of exemplary embodiments which are illustrated in the drawing. 1 and 2 each show a sleeve buffer in longitudinal section.

Die beiden Hülsenpuffer bestehen im wesentlichen aus einem Pufferstößel 1 mit Pufferteller 1a, einer Pufferhülse 2 mit einer fahrzeugseitig anschraubbaren Grundplatte 2a sowie einer hier symbolisch gezeichneten Feder 3.The two sleeve buffers essentially consist of a buffer plunger 1 with a buffer plate 1 a, a buffer sleeve 2 with a base plate 2 a screwable on the vehicle side, and a spring 3 symbolized here.

Um den Ausschub des Hülsenpuffers zu begrenzen und damit auch die Vorspannkraft der Feder 3 zu bestimmen, ist gemäß Fig. 1 am offenen Ende des Pufferstößels 1a ein Haltering 5 angeschweißt, der mit einem Bund 2b der Pufferhülse 2 formschlüssig zusammenwirkt. Bei dem Puffer nach Fig. 2 sind für die Ausschubbegrenzung zwei Halbschalen 6 vorgesehen, die in einer Umfangsnut der Pufferhülse 2 gehalten sind und gegen einen Bund 1c des Pufferstößels 1 anliegen.In order to limit the extension of the sleeve buffer and thus also to determine the pretensioning force of the spring 3, a retaining ring 5 is welded onto the open end of the buffer tappet 1 a, which cooperates in a form-fitting manner with a collar 2 b of the buffer sleeve 2. In the buffer according to FIG. 2, two half-shells 6 are provided for the extension limitation, which are held in a circumferential groove of the buffer sleeve 2 and bear against a collar 1c of the buffer tappet 1.

In beiden Ausführungsbeispielen wird durch eine Paßfeder 7 und eine zugehörige Längsnut 2c bzw. 1d erreicht, daß der Pufferstößel 1 und die Pufferhülse 2 in Umfangsrichtung drehfest miteinander verbunden sind.In both exemplary embodiments, a feather key 7 and an associated longitudinal groove 2c and 1d ensure that the buffer tappet 1 and the buffer sleeve 2 are connected to one another in a rotationally fixed manner in the circumferential direction.

Der jeweilige, in Seitenansicht rechteckförmige Pufferteller 1a besteht aus einem oberflächenhärtbaren Werkstoff, wie beispielsweise Cf 35. Nach der Oberflächenhärtung durch Flammhärten oder auf induktivem Wege weist der Pufferteller 1a eine Härte nach Vickers von mindestens 350 HV 30 bei Rht 250 >= 3 mm auf. Entsprechend DIN 50 133 ist 350 der Härtewert; HV 30 bedeutet, daß dieser Härtewert mit einer Prüfkraft von 294,2 N und einer Einwirkzeit von 10s bis 15s zu bestimmen ist. Die weiter angegebene, nach DIN 50 190 Teil 2 zu ermittelnde Einhärtungstiefe setzt sich zusammen aus dem Kurzzeichen Rht, der Grenzhärte nach Vickers und dem Betrag der Einhärtungstiefe in mm. Mit dem Werkstoff Cf 35 können ohne weiteres höhere Werte erreicht werden, beispielsweise 450 HV 30 bei Rht 350 >= 3 mm.The respective buffer plate 1a, which is rectangular in side view, consists of a surface-hardenable material, such as Cf 35. After surface hardening by flame hardening or by induction, the buffer plate 1a has a Vickers hardness of at least 350 HV 30 at Rht 250> = 3 mm. According to DIN 50 133, 350 is the hardness value; HV 30 means that this hardness value can be determined with a test force of 294.2 N and an exposure time of 10s to 15s. The further specified hardening depth to be determined in accordance with DIN 50 190 Part 2 is made up of the abbreviation Rht, the limit hardness according to Vickers and the amount of the hardening depth in mm. With the material Cf 35 higher values can easily be achieved, for example 450 HV 30 at Rht 350> = 3 mm.

Der Pufferteller 1a wird in der Regel durch Schmieden geformt, wobei die zugehörige Erwärmung zu einer Entkohlung der äußeren Werkstoffschicht führt. Im Hinblick darauf wird der Pufferteller 1a an seiner Stoßfläche vor der Oberflächenhärtung mit einer Tiefe von etwa 1,5 mm bearbeitet, so daß entkohlter Werkstoff sicher entfernt ist. Bei dieser Bearbeitung sollte eine Rautiefe Rz =< 16 µm eingehalten werden, um ein leichtes Gleiten zusammenwirkender Pufferteller 1a zu erreichen. Diese gute Gleiten kann durch ein späteres Auftragen eines Gleitlackes noch verbessert werden.The buffer plate 1a is usually formed by forging, the associated heating leading to decarburization of the outer material layer. In view of this, the buffer plate 1a is machined on its abutting surface before the surface hardening to a depth of about 1.5 mm, so that decarburized material is safely removed. During this processing, a roughness depth R z = <16 µm should be maintained in order to achieve a smooth sliding of interacting buffer plates 1a. This good gliding can be improved by applying a lubricant later.

Für den Pufferteller 1a des Hülsenpuffers nach Fig. 1 wurde der Werkstoff Cf 35 gewählt, um den Pufferteller 1a durch eine umlaufende Schweißnaht 4 mit dem aus üblichem Stahl (z. B. St 52-3) bestehenden rohrförmigen Teil 1b des Pufferstößels 1 verbinden zu können. Das Schweißen bereitet keine Schwierigkeiten, wenn die Bauteile 1a und 1b auf eine Temperatur in der Größenordnung von 150 °C bis 200 °C vorgewärmt werden.1, the material Cf 35 was selected in order to connect the buffer plate 1a by a circumferential weld seam 4 to the tubular part 1b of the buffer tappet 1, which is made of conventional steel (e.g. St 52-3) can. The welding presents no difficulties if the components 1a and 1b are on one Temperature in the order of 150 ° C to 200 ° C to be preheated.

Bei dem Hülsenpuffer nach Fig. 2 sind der Pufferteller 1a und der rohrförmige Teil 1b des Pufferstößels 1 durch Schrauben 8 vereinigt. In diesem Fall kann der Pufferteller 1a ohne weiteres aus einem oberflächenhärtbaren Werkstoff mit höherem Kohlenstoffanteil gebildet werden. Damit im Bereich der Durchgangsbohrungen des Puffertellers 1a keine Risse auftreten können, sind beim Härten entsprechende Vorsichtsmaßnahmen zu treffen; dazu gehört z. B. das Verwenden eines milden Abschreckmittels.In the case of the sleeve buffer according to FIG. 2, the buffer plate 1a and the tubular part 1b of the buffer tappet 1 are united by screws 8. In this case, the buffer plate 1a can easily be formed from a surface-hardenable material with a higher carbon content. To ensure that no cracks can occur in the area of the through bores of the buffer plate 1a, appropriate precautionary measures must be taken during hardening; this includes z. B. Using a mild quenching agent.

Durch die Erfindung steht ein Hülsenpuffer zur Verfügung, der einfach und kostengünstig herstellbar ist. Im Betrieb zeichnet sich dieser Hülsenpuffer vor allem dadurch aus, daß sein Pufferteller gegenüber Verschleiß widerstandsfähig ist. Der erfindungsgemäße Puffer ist dadurch auch für lange zweiachsige Güterwagen bestens geeignet, bei denen besonders in engen Gleisbögen große Reibbewegungen zwischen anliegenden Puffertellern auftreten.The invention provides a sleeve buffer that is simple and inexpensive to manufacture. In operation, this sleeve buffer is characterized above all by the fact that its buffer plate is resistant to wear. As a result, the buffer according to the invention is also ideally suited for long two-axle freight wagons in which large frictional movements occur between adjacent buffer plates, particularly in narrow bends.
