Abstract

The bush has a core and an outer sleeve of metal or plastic, and a pad of elastomer material, which is located between core and outer sleeve and in adhesive connection with both. The core has a wave contour, and is conical.

Description

Die Erfindung betrifft eine Buchse, insbesondere für Schienenfahrzeuge, wobei die Buchse folgende Bauteile umfaßt, nämlich
The invention relates to a socket, in particular for rail vehicles, the socket comprising the following components, namely

  • - einen Kern aus Metall oder Kunststoff (z. B. auf Basis von Polyphenylenether);- a core made of metal or plastic (e.g. based on polyphenylene ether);
  • - eine Außenhülse, die ebenfalls aus Metall oder Kunststoff besteht; sowie- An outer sleeve, which is also made of metal or plastic; such as
  • - ein Polster aus elastomerem Werkstoff, das zwischen Kern und Außenhülse angeordnet ist und dabei mit diesen beiden Bauteilen haftend verbunden ist.- A cushion of elastomeric material between the core and the outer sleeve is arranged and is adhesively connected to these two components.

Durch immer kleinere Bauraumvorgaben müssen insbesondere die Artikel im Schienenfahrzeugbereich - hier in Form der Buchse - ständig kleiner werden. Dies hat zur Folge, daß die Kraft, die auf 1 cm2 Haftfläche wirkt, immer größer wird und nun die Grenze bei einigen Artikeln erreicht hat.Due to ever smaller installation space requirements, the articles in the rail vehicle area in particular - here in the form of the socket - have to become smaller and smaller. As a result, the force that acts on 1 cm 2 of adhesive surface is increasing and has now reached the limit for some articles.

Aufgabe der Erfindung ist es daher, die Haftfläche bei gleicher Baugröße zu vergrößern oder daraus folgend, Artikel geometrisch kleiner auszulegen.The object of the invention is therefore to increase the adhesive surface with the same size or, consequently, to make articles geometrically smaller.

Gelöst wird diese Aufgabe gemäß Kennzeichen des Patentanspruches 1 dadurch, daß der Kern eine Wellenkontur aufweist.This object is achieved according to the characterizing part of claim 1 in that the core has a wave contour.

Gemäß Patentanspruch 2 ist dabei der Kern vorteilhafterweise konusförmig ausgebildet.According to claim 2, the core is advantageously conical educated.

Als ein Beispiel für die Auslegung der Wellenkontur im Vergleich zum herkömmlichen Kern wird der Kern einer Konusfeder herangezogen, und zwar anhand einer Berechnung in Verbindung mit einer schematischen Zeichnung. As an example of the design of the shaft contour compared to the conventional one The core of a cone spring is used, based on one Calculation in connection with a schematic drawing.  

Vorgaben:
S = 10,2 cm
d1 = 6,4 cm
d2 = 2,4 cmRequirements:
S = 10.2 cm
d1 = 6.4 cm
d2 = 2.4 cm

Berechnung der Fläche mit normalen Kern:
Calculating the area with normal core:

Bei der Berechnung der Fläche mit Wellenform, wird die Länge S folgendermaßen neu berechnet:
rw = Wellenradius
nr = Anzahl der halben Kreisbogen
Sw = Länge der geglätteten Welle
Aw = Fläche mit Wellenform.When calculating the area with the waveform, the length S is recalculated as follows:
r w = shaft radius
n r = number of half arcs
S w = length of the smoothed wave
A w = area with a waveform.

Berechnung von Aw bei einem Radius von rw = 0,1 cm:
Calculation of A w with a radius of r w = 0.1 cm:

Vereinfachung der Formel
Simplify the formula

Bei genauerer Betrachtung vergrößert sich die Fläche bei Verwendung von Kreisbögen um π/2, da sich der rw = Wellenradius in der Formel herauskürzt.On closer inspection, the area increases when using arcs by π / 2, since the r w = wave radius is shortened in the formula.
