Description

Vorrichtung zum Lockern von durch einen Bund zusammengehaltenen, an Fahrzeugen, insbesondere Eisenbahnwagen, angeordneten Federblättern Die bei Fahrzeugen aller Art, insbesondere bei Eisenbahnwagen, in Anwendung befindlichen Tragfedern sind aus @einzelnen Federblättern gebildet, die durch einen Bund zusammengehalten werden, wobei zwischen dem Blattfederpaket und dem Bund ein Keil oder eine sonstige Zwischenlage mit eingepreßt ist. Bei Erneuerung eines Federblattes (Ersatz beschädigter Federblätter durch neue oder Nachbearbeitung einzelner Federblätter) muß das Federblattpaket in dem Bund gelockert und die Zwischenlage durch Schläge aus dem Bund herausgetrieben werden. Das Austreiben des Keiles oder der Zwischenlage ist mühevoll und zeitraubend. Die Erfindung besteht nun darin, daß der Keil mittels seines unter maschineller Druckeinwirkung stehenden Stößels gelöst wird. Zweckmäßig ist der Stößel an einer Schwinge angeordnet, die gelenkig mit einem unter hydraulischem Druck stehenden Kolben in Verbindung steht, wobei der Druck in einer zur Wagerechten geneigten Richtung wirkt.Device for loosening those held together by a collar Vehicles, in particular railroad cars, the spring leaves arranged in vehicles All types of suspension springs in use, especially in railway wagons are formed from individual spring leaves that are held together by a collar be, with a wedge or other between the leaf spring package and the collar Interlayer is also pressed in. When replacing a spring leaf (replacement of damaged Spring leaves by new or reworking of individual spring leaves) must be the spring leaf package loosened in the federal government and the intermediate layer driven out of the federal government by blows will. Driving out the wedge or liner is laborious and time consuming. The invention consists in that the wedge by means of its under machine Pressure is released. The plunger is useful on one Swing arm arranged, the articulated with a standing under hydraulic pressure Piston communicates with the pressure in a direction inclined to the horizontal works.

Der Erfindungsgegenstand ist in der Zeichnung dargestellt. In einem Rahmengestell i ist ein hydraulischer Zylinder a mit dem hierin untergebrachten Kolben q. angeordnet. Dieser Kolben q. steht unter der Einwirkung eines Gewichts 3, das das Bestreben hat, den Kolben q. in die Ausgangsstellung zurückzubewegen. Dies geschieht, sobald das Druckwasser aus dem Zylinder a abgelassen wird. An dem freien Ende des Kolbens q. ist gelenkartig eine Schwinge 5 befestigt, die an ihrem Ende einen keilförmig zugespitzten Stößel 6 mit nach dem Gelenkpunkt hin gerichteter Spitze trägt. Der Rahmen i ist mit einem als Lager für den Federbund 7 dienenden Querstück 8 versehen. Wie in der Zeichnung dargestellt, wird der Bund der zu bearbeitenden Tragfeder in das Querstück 8 ,eingelegt. Der Handhebel io trägt auf seiner Welle noch den die Schwinge 5 unterfassenden Hebel id, so daß mit dem Hebel i o die Schwinge in und außer Arbeitsstellung gebracht wird.The subject of the invention is shown in the drawing. In one Frame i is a hydraulic cylinder a with the one housed therein Piston q. arranged. This piston q. is under the action of a weight 3, which has the tendency to move the piston q. to move back to the starting position. This happens as soon as the pressurized water is drained from the cylinder a. To the free end of the piston q. is articulated a rocker 5 attached to her End of a wedge-shaped tapered plunger 6 with directed towards the hinge point Lace wears. The frame i is provided with a bearing for the spring collar 7 Cross piece 8 provided. As shown in the drawing, the collar is the one to be machined Suspension spring in the cross piece 8, inserted. The hand lever io carries on its shaft nor the lever id, which underlies the rocker 5, so that the rocker with the lever i o is brought into and out of working position.

Die Handhabung der Einrichtung gestaltet sich so, daß, nachdem die Tragfeder eingelegt ist, der Stößel 6 so eingeschwenkt wird, daß die Stößelspitze bei Unterdrucksetzung des Zylinders a auf das Keilstück i i oder auf die sonstige Zwischenlage einwirkt und diese aus dem Federbund 7 herauszuschieben sucht. Hierbei ist von besonderer Wichtigkeit, daß der Stößel in einer zur Wagerechten geneigten Richtung wirkt, die treibende Kraft also in eine in wagerechter Ebene wirkende und in eine in lotrechter Ebene wirkende Kraft zerlegt wird. Erstere sucht den Keil auszutreiben, während die letztere senkrecht auf das Federblatt drückt und dadurch das schnelle Entfernen des Keiles fördert.The handling of the device is such that after the Suspension spring is inserted, the plunger 6 is pivoted in such a way that the plunger tip when the cylinder a is pressurized on the wedge piece i i or on the other Intermediate layer acts and seeks to push it out of the spring collar 7. Here It is of particular importance that the plunger is inclined to the horizontal Direction acts, so the driving force acts in a horizontal plane and is broken down into a force acting in a vertical plane. The former is looking for the wedge to drive out, while the latter presses perpendicularly on the spring leaf and thereby the rapid removal of the wedge promotes.

Bei Verzögerung der Lockerung der Zwischenlage genügen leichte Hammerschläge auf den Stößel 6, um die Lockerung in sicherster Weise durchzuführen.If the loosening of the intermediate layer is delayed, light hammer blows on the plunger 6 are sufficient to carry out the loosening in the safest manner.
