Abstract

The flexible mountings are used for flexible mounting of axle boxes of supercritical bogies. These mountings ensure that the vehicle has relatively low vertical flexibility and is quite stiff in the transverse direction. The mountings are flexible in the longitudinal direction. The axle box has on each side a mandrel which is on a common centre line. the mandrels are enclosed by enclosing rubber spring which are held in tubular housings attached to the bogie frame. The mandrels can also be staggered at different levels or their skew centre lines may intersect at the axle centre in plan view to improve stability.

Description

Elastische Lagerung für die Achslager der Drehgestelle von Schienenfahrzeugen Die Erfindung betrifft eine elastische Lagerung für die Achslager der Drehgestelle von Schienenfahrzeugen, insbesondere für die Achslager sogenannter Uberkritischer Drehgestelle. Elastic mounting for the axle bearings of the bogies of rail vehicles The invention relates to an elastic mounting for the axle bearings of the bogies of rail vehicles, especially for the axle bearings of so-called supercriticals Bogies.

An die Drehgestelle der vorgenannten Art werden die Forderungen gestellt, daß nur eine geringe vertikale Einfederung auftritt und daß die Achse in Fahrtrichtung weich und quer zur Fahrtrichtung sehr hart geführt ist. Diese Forderungen werden von den bekannten elastischen Lagerungen für di Achslager der Drehgestelle nur Jeweils teilweise erfüllt.The requirements for the bogies of the aforementioned type are made, that only a slight vertical deflection occurs and that the axis is in the direction of travel is soft and very hard at right angles to the direction of travel. These demands will be of the known elastic bearings for the axle bearings of the bogies only each partially fulfilled.

Der Erfindung liegt die Aufgabe zugrunde, eine elastische Lagerung zu schaffen, die alle Forderungen erfüllt, die an Drehgestelle der genannten Art gestellt werden und die darüber hinaus einfach und wirtschaftlich ist.The invention is based on the object of an elastic mounting to create that meets all the requirements that are placed on bogies of the type mentioned and which is also simple and economical.

D5e Lösung der gestellten Aufgabe besteht darin, daß beiderseits des Achslagers Je ein Dorn angeordnet ist, um den ein von einem Gehäuse umschlossener ringförmiger Gummikörper gelegt ist.D5e solution of the problem is that on both sides of the Axle bearing a mandrel is arranged around which one is enclosed by a housing annular rubber body is placed.

Gemäß einem weiteren Schritt der Erfindung sind die Dorne und/ oder die Gehäuse konisch ausgebildet, so daß durch Vorspannen oder Entlasten mittels einer Unterlage oder durch Spannschrauben eine Einstellung der gewünschten Härte des Lagers möglich ist.According to a further step of the invention, the mandrels and / or the housing is conical, so that by means of biasing or relieving a base or a setting of the desired hardness by means of clamping screws of the camp is possible.

Zweckmäßigerweise stützen sich die Gehäuse gegen eine schräg verlaufende Wand des Wagenkastens ab. Beim Aufsetzen der Drehgestelle werden dann die Gehäuse gegen die zugehörigen Dorne gedrückt, so daß die ringförmigen Gummikörper,eine Vorspannung erhalten.The housings are expediently supported against an inclined one From the wall of the car body. When the bogies are put on, the housings are then pressed against the associated mandrels, so that the annular rubber body, a bias obtain.

Nach einem anderen Merkmal der Erfindung bilden die Mittellinien der Dorne mit der Mittellinie des Achslagers einen Winkel, der zwischen 450 und 900 betragen kann. Dadurch kann der Lauf der Räder auf den Schienen günstig beeinflußt werden Um Schwankungen aller Art aufzufangen, ist es zweckmäßig, daß die Dorne gegeneinander versetzt angeordnet sind.According to another feature of the invention, the center lines form the With the center line of the journal bearing, the mandrel forms an angle between 450 and 900 can be. As a result, the running of the wheels on the rails can be favorably influenced In order to absorb fluctuations of all kinds, it is advisable that the mandrels against each other are arranged offset.

In weiterer Ausgestaltung der Erfindung ist zur Aufnahme der Vertikalbelastung zwischen dem Achslager und dem Wagenkasten eine an sich bekannte Druckfeder vorgesehen. Die Druckfeder ist so ausgebildet, daß sie Querbewegungen in allen Richtungen mitmachen kann.In a further embodiment of the invention is to absorb the vertical load between the axle box and the car body a known one Compression spring provided. The compression spring is designed so that it has transverse movements can participate in all directions.

Die Erfindung ist anhand der Zeichnung näher erläutert. Es zeigen: Fig. 1 ein elastisch gelagertes Achslager in Seitenansicht, wobei die elastische Lagerung im Längsschnitt dargestellt ist, Fig. 2 ein elastisch gelagertes Achslager in Draufsicht und Fig. 3 ein weiteres elastisch gelagertes Achslager in Seitenansicht, wobei ebenfalls die elastische Lagerung im Längsschnitt dargestellt ist.The invention is explained in more detail with reference to the drawing. Show it: Fig. 1 shows an elastically mounted axle bearing in side view, the elastic Storage is shown in longitudinal section, Fig. 2 an elastically mounted axle bearing in plan view and FIG. 3 a further elastically mounted axle bearing in side view, the elastic mounting is also shown in longitudinal section.

Bei dem in Fig. 1 dargestellten Ausführungsbeispiel ist beiderseits des Achslagers 1 Je ein Dorn 2 angeordnet, Um jeden Dorn 2 ist ein ringförmiger Gummikörper 3 gelegt, der von einem Gehäuse 4 umschlossen ist. Die Gehäuse 4 stützen sich gegen eine schräg verlaufende Wand 5 des Wagenkastens 6 ab. Zwischen dem Achslager 1 und dem Wagenkasten 6 ist eine Druckfeder 7 vorgesehen.In the embodiment shown in Fig. 1 is on both sides of the axle bearing 1 each arranged a mandrel 2, around each mandrel 2 is an annular one Rubber body 3 is placed, which is enclosed by a housing 4. Support the housings 4 against a sloping wall 5 of the car body 6. Between the axle box 1 and the car body 6, a compression spring 7 is provided.

Bei dem Ausführungsbeispiel gemäß Fig. 2 ist das Achslager 1 mit Dornen 2 versehen, deren Mittellinien 2a mit der Mittellinie la des Achslagers 1 einen Winkel a bilden.In the embodiment according to FIG. 2, the axle bearing 1 is provided with thorns 2 provided, the center lines 2a with the center line la of the axle bearing 1 a Form angle a.

Das in Fig, 3 dargestellte Ausführungsbeispiel zeigt ein Achslager 1, das mit gegeneinander versetzten Dornen 2.1 versehen ist. Die Dorne 2.1 und die Gehäuse 4.1 sind konisch ausgebildet.The embodiment shown in Fig. 3 shows an axle bearing 1, which is provided with staggered thorns 2.1. The mandrels 2.1 and the Housing 4.1 are conical.
