Description

Die Erfindung betrifft Drehgestelle für Eisenbahnwagen u. dgl., deren Tragfedern als Schraubenfedern ausgebildet sind. Sie erstreckt sich insbesondere auf die zum Vorspannen dieser zwischen zwei Federtellern angeordneten Schraubenfedern benutzten Schraubenbolzen.The invention relates to bogies for railroad cars and the like, whose suspension springs are helical springs are trained. It extends in particular to the helical springs which are arranged between two spring plates for pretensioning them used bolts.

Die vorliegende Erfindung bezweckt, die Teile der Aufhängevorrichtung für das Drehgestell so auszubilden, daß sie vor Beschädigungen bewahrt sind.The present invention aims at the parts of the suspension device for the bogie to be trained in such a way that they are protected from damage.

Das wesentliche Kennzeichen der Erfindung besteht darin, daß das Gewinde des Schraubenbolzens auf seiner ganzen Länge von der Mutter bedeckt ist und daß sein Innendurchmesser ebenso groß oder größer ausgeführt ist als der Schaftdurchmesser des Bolzens, hierdurch ist es möglich, die Mutter teilweise über den Bolzenschaft herabzuschrauben, so daß das Bolzengewinde auf seiner ganzen Länge innerhalb der Mutter liegt. Infolge dieser Anordnung wird das Bolzengewinde vor Beschädigungen geschützt.The main feature of the invention is that the thread of the screw bolt is covered over its entire length by the nut and that its inner diameter is made just as large or larger than the shaft diameter of the bolt, as a result it is possible to partially unscrew the nut over the bolt shaft so that the Bolt thread lies along its entire length within the nut. As a result of this arrangement the bolt thread is protected from damage.

In der Zeichnung ist ein AusführungsbeispielIn the drawing is an exemplary embodiment

des Erfindungsgegenstandes dargestellt, und zwar zeigt die Abbildung einen Querschnitt durch eine Tragfederaufhängung mit einem Schraubenbolzen gemäß der Erfindung.of the subject matter of the invention, namely the figure shows a cross section by a suspension spring suspension with a screw bolt according to the invention.

Zwischen dem mit dem nicht dargestelltenBetween the one with the one not shown

Laufwerk verbundenen Teil 3 und dem Drehgestellrahmen 5 ist die Tragfeder 4 angeordnet und in bekannter Weise an beiden Enden von einem Federteller 7, 8 begrenzt. Der Federteller 7 liegt in einer Ausbohrung 6 des Teiles 3 und kann hier starr verbunden oder leicht abnehmbar sein. Im zweiten Falle ist es angebracht, den Federteller mittels eines Bajonettverschlusses von unten in den Teil 3 einzurühren. Der Federteller 8 legt sich gegen eine am Drehgestellrahmen befestigte Pratze 1 an. Die Federteller 7 und 8 sind mit Bohrungen für den zum Vorspannen der Tragfeder dienenden Schraubenbolzen 12 versehen, die zwecks Aufnahme des Bolzenkopfes 14 bzw. der Bolzenmutter 16 teilweise erweitert sind und in warzenartigen Vorsprüngen der Teller angeordnet sein können.Drive connected part 3 and the bogie frame 5, the suspension spring 4 is arranged and limited in a known manner at both ends by a spring plate 7, 8. The spring plate 7 lies in a bore 6 of part 3 and can be rigidly connected here or easily removable be. In the second case, it is appropriate to attach the spring plate by means of a bayonet lock to stir into part 3 from below. The spring plate 8 lies against one on the bogie frame attached claw 1. The spring plate 7 and 8 are with holes for the Biasing the suspension spring serving screw bolts 12 provided for the purpose of receiving the Bolt head 14 and the bolt nut 16 are partially expanded and in wart-like projections the plate can be arranged.

Das in den Bolzen 12 eingeschnittene Gewinde 19 hat einen Kerndurchmesser, der erfindungsgemäß wenigstens so groß wie der Durchmesser des Bolzenschaftes ist. Auf dem Gewinde sitzt eine Mutter 16, die das ganze Gewinde bedeckt, so daß es während des Betriebes vor Beschädigungen geschützt ist.The thread 19 cut into the bolt 12 has a core diameter that is according to the invention at least as large as the diameter of the bolt shank. On the thread sits a nut 16, the whole Thread covered so that it is protected from damage during operation.
