Description

Die Erfindung betrifft eine Weiterbildung des Federgehänges für Fahrzeuge, insbesondere Kraftfahrzeuge, nach Patent 904 024. Nach diesem Patent beruht das Gehänge auf dem schon von früher her bekannten Prinzip der Gewindelagerung, wonach der Lagerbolzen ein Gewindezapfen, die Lagerbuchse eine Gewindehülse ist. Neu dagegen war der Ersatz der Gewindehülse durch eine Schraubenfeder, die mit Reibung in das Federauge bzw. den Federbock eingedreht und in die ein Gewindebolzen mit Rundgewinde eingeschraubt wird. Dieser ist in bekannter Weise mit den Laschen des Gehänges verbunden. Der Zweck der vorliegenden Erfindung ist, die Schraubenfeder nicht nur durch Reibung gegen axiale Verschiebung im Federauge zu sichern, sondern durch Anordnung von Anschlägen ihre Unverrückbarkeit im Federauge zu begründen.The invention relates to a development of the Spring hanger for vehicles, especially motor vehicles, according to patent 904 024. According to this Patent, the hanger is based on the previously known principle of the thread bearing, after which the bearing pin is a threaded pin and the bearing bush is a threaded sleeve. New against it was the replacement of the threaded sleeve with a helical spring, which with friction in the spring eye or screwed in the spring bracket and screwed into a threaded bolt with a round thread will. This is connected in a known manner to the straps of the hanger. The purpose of present invention is, the coil spring not only by friction against axial displacement to secure in the spring eye, but by arranging stops their immovability in the spring eye to justify.

Die Zeichnung veranschaulicht eine Ausführungsform der Erfindung durch einen Längsschnitt in der Gehängeachse.The drawing illustrates an embodiment of the invention through a longitudinal section in FIG the suspension axis.

In der vorbekannten Weise ist als Ersatz der Gewindebuchse eine Schraubenfeder 1 vorgesehen, die aus Draht von zweckmäßigem, im übrigen beliebigem Querschnitt hergestellt ist. Die Feder 1 hat die Form einer Druckfeder, d. h. ihre Windungen stehen der Steigung am Gewindebolzen entsprechend etwas voneinander ab; sie wird beim Zusammenbau des Gehänges unter Verringerung ihres Durehmessers in das Federauge 2 oder den Federbock hineingedreht. Dies geschieht mittels des Gewindebolzens 3, der mit Rundgewinde ausgestattet ist und sich in der Feder 1 unter axialer Sicherung drehen kann, wie es ohne die letztere bei den gebräuchlichen glatten Bolzen in seiner Buchse geschieht. Der Bolzen 3 ist in der üblichen Weise an seinen beiden Enden mit den Laschen 4 des Gehänges verbunden.In the previously known manner, the replacement is the Threaded bushing a coil spring 1 is provided, which is made of wire of appropriate, otherwise arbitrary Cross-section is made. The spring 1 is in the form of a compression spring; H. their coils stand slightly from each other according to the pitch on the threaded bolt; she will at Assemble the hanger while reducing its diameter in the spring eye 2 or the Spring bracket screwed in. This is done by means of the threaded bolt 3, which is equipped with a round thread is and can rotate in the spring 1 with axial locking, as it would without the latter happens with the common smooth bolts in its socket. The bolt 3 is in the usual Way connected at both ends with the tabs 4 of the hanger.

Diesen bekannten Einrichtungen gegenüber ist bei der vorliegenden Erfindung eine zusätzliche und vollständige Sicherung der Schraubenfeder 1 gegen axiales Verschieben im Federauge 2 oder -bock vorgesehen. Dabei stehen die beiden äußersten Windungen der Feder 1 über die Seitenflächen des Federauges vor, und es werden durch Anschleifen Falze 7 gebildet, mit denen sich die Feder 1 fest an die Seitenflächen anlegt. Diese Wirkung kann, abgesehen von der Anbringung der Falze 7, ohne weitere Bearbeitung der Feder 1 erzielt werden, da die freien Federenden sich durch Entspannen gegenüber den mittleren, unter Druck stehenden Windungen etwas aufrollen und dabei einen vergleichsweise größeren Durchmesser annehmen, der sie zur Anlage an die Seitenflächen des Federauges befähigt. Compared to these known devices is an additional and in the present invention Complete securing of the helical spring 1 against axial displacement in the spring eye 2 or bracket intended. The two outermost turns of the spring 1 are above the side surfaces of the Feather eye before, and it is formed by grinding seams 7, with which the spring 1 firmly applied to the side surfaces. This effect can, apart from the application of the folds 7, without further processing of the spring 1 can be achieved, since the free spring ends are opposite each other by relaxing Roll up the middle, pressurized turns a little and do a comparative assume a larger diameter, which enables them to rest on the side surfaces of the spring eye.

Ein weiterer in derselben Richtung wirksamer Vorzug der Erfindung besteht darin, daß die Gewindegänge des Bolzens 3, im Profil gesehen, eine verhältnismäßig flache Wellenlinie darstellen. Auf diese Weise wird, wie aus der Zeichnung leicht ersichtlich, bei der Einwirkung von Fliehkräften in dem Bolzen 3 eine axiale Schubbeanspruchung ausgelöst. Diese verursacht zwischen den Gewindegängen des Bolzens 3 und den zugeordneten Windungen der Schraubenfeder 1 Keilwirkungen, die bestrebt sind, die Federwindungen mit noch größerer Kraft, als das ohnedies geschieht, an die Innenwandung des Federauges 2 anzupressen. Damit wird die Sicherheit gegen axiale Verschiebung der Feder 1 im Federauge 2 entsprechend erhöht.Another advantage of the invention that is effective in the same direction is that the threads of the bolt 3, seen in profile, represent a relatively flat wavy line. on as can be easily seen from the drawing, this is the case with the action of centrifugal forces in the bolt 3 triggered an axial shear stress. This causes between the threads of the bolt 3 and the associated turns of the helical spring 1 are wedge effects, who strive to the spring coils with even greater force than that happens anyway, to the Press the inner wall of the spring eye 2. This increases the security against axial displacement the spring 1 in the spring eye 2 increased accordingly.
