Description

Die Erfindung betrifft ein Verfahren zur kraftschlüssigen Verbindung sowie eine kraftschlüssige Verbindung von zwei Bauteilen, insbesondere Verbindung von zwei Bauteilen unterschiedlichen WerkstoffsThe invention relates to a method for non-positive connection and a frictional connection of two components, in particular connection of two components of different material

Die betriebssichere Herstellung einer kraftschlüssigen Verbindung zwischen zwei Bauteilen bei betriebsbedingt auftretenden dynamischen Kräften stellt ein Problem dar, insbesondere, wenn zwei Bauteile aus unterschiedlichen Werkstoffen, z. B. ein Gelenk oder Kupplungsbock aus Stahlguss an ein Strangpressprofil aus einer Aluminiumlegierung, verbunden werden müssen, was im Schienenfahrzeugbau oft verwirklicht werden muss.The reliable production of a non-positive connection between two components with operationally occurring dynamic forces is a problem, especially if two components made of different materials, eg. As a joint or coupling bracket made of cast steel to an extruded profile of an aluminum alloy, must be connected, which often has to be realized in rail vehicle.

Die Verbindung muss bei Fahrzeugen, insbesondere bei hochbelasteten Schienenfahrzeugen den betriebsbedingten, dynamischen Kräften, z. B. beim Bremsen ebenso wie den erheblich höheren Kräften eines Auflaufstoßes und Anfahren an einer sicherheitsrelevanten Stelle im Zugverband genügen.The connection must in vehicles, especially in heavily loaded rail vehicles the operational, dynamic forces, such. B. when braking as well as the significantly higher forces of a collision shock and start at a safety-relevant point in the train suffice.

Es ist bekannt, eine Verbindung mit geeigneten Schrauben derart vorzuspannen, dass deren Vorspannung über die gesamte Lebensdauer weitgehend aufrechterhalten wird. Als geeignete Schrauben sind z. B. Dehnschrauben aus der DIN 267 bekannt. Bei Werkstoffen geringerer Festigkeit als Stahl, z. B. bei Aluminiumlegierungen ist es aber oft schwierig, die notwendigen Kräfte auf den Bauteilen abzusetzen und abzutragen.It is known to bias a connection with suitable screws such that their bias is largely maintained over the entire life. As suitable screws z. B. expansion bolts from DIN 267 known. For materials of lower strength than steel, z. As with aluminum alloys, but it is often difficult to settle the necessary forces on the components and remove.

Schrauben langer Klemmlänge reduzieren die unvermeidlichen Setzungsverluste und damit den Verlust der Vorspannkraft. Derartige Schrauben, auch als Dehnschrauben sind z. B. aus der DE 39 18 300 A1 bekannt. Hier wird eine Radsatzführung für Drehgestelle für Schienenfahrzeuge gezeigt. Mittels einer Dehnschraube sind die beiden Federblattlenker am Achslagergehäuse befestigt und die Gummizwischenlagen exakt vorspannbar. Durch entsprechend gewählte Vorspannung der Dehnschraube ist die horizontale Längssteifigkeit der Gummizwischenlagen genau einstellbar. Auch wird eine Druckplatte (Zahnplatte) gezeigt, die zwischen dem Kopf der Mutter und einem Federblattlenker angeordnet ist. Nach dem Lösen der Schraubverbindung ist die aufgebrachte Vorspannung auch zwischen Druckplatte und Federblattlenker weggenommen. Trotz Zahnplatte und insbesondere bei glatten Druckplatten, wie z. B. beim Anschluss des Kupplungsbocks beim ICE und ICE 2 an ein Aluminiumstrangpressprofil verwendet, mindern auch kleine Querverschiebungen zwischen Druckplatte und Trägerteil die Qualität der Verbindung hinsichtlich einer möglichst über die gesamte Betriebsdauer aufrechtzuhaltenden Vorspannkraft, insbesondere auch bei Wechselbeanspruchungen in allen 3 AchsenLong clamping length screws reduce the inevitable settlement losses and thus the loss of preload force. Such screws, as expansion bolts are z. B. from DE 39 18 300 A1. Here is a wheelset for bogies shown for rail vehicles. By means of an expansion screw, the two spring leaf links are attached to the axle box housing and the rubber pads are exactly biased. By appropriately selected bias of the expansion screw, the horizontal longitudinal stiffness of the rubber blanks is precisely adjusted. Also, a pressure plate (tooth plate) is shown, which is arranged between the head of the mother and a spring leaf link. After loosening the screw, the applied preload is removed between the pressure plate and spring leaf link. Despite tooth plate and especially in smooth printing plates, such. B. used when connecting the coupling block in ICE and ICE 2 to an aluminum extruded profile, also reduce small transverse displacements between the pressure plate and support member quality of the compound with respect to a possible over the entire service life to be maintained biasing force, especially with alternating stresses in all 3 axes

Aus der US-A-5,410,847 ist es bekannt, ein Trägerteil an einem stahlummantelten Betonträger über Schraubverbindungen zu befestigen, wobei zwischen Mutterauflage und Mantelfläche des Trägerteils jeweils ein Druckverteilstück angeordnet ist. Die Druckverteilstücke sind als Gegenlager am Trägerteil durch Schweißnähte vor Herstellung der Schraubverbindung fixiert. Da es sich um massive Stahlträger bzw. Stahlwerkstoffe handelt, sind besondere Probleme hinsichtlich der Krafteinleitung und Kraftabsetzung und größere Setzungsverluste bei der Schraubenverbindung bei diesen Verbindungspartnern und einer vorwiegend statischen Beanspruchung nicht zu erwarten. Hinweise zu problematischen Schraubverbindungen zwischen zwei unterschiedlich festen Werkstoffen, z.B. zwischen Stahlwerkstoffen und Aluminiumwerkstoffen, gibt dieses Dokument nicht.From US-A-5,410,847 it is known to attach a support member to a steel-clad concrete beam via screw, wherein between the nut support and lateral surface of the support member each have a pressure distribution piece is arranged. The Druckverteilstücke are fixed as an abutment on the support member by welds before making the screw. Since these are massive steel beams or steel materials, special problems with regard to force introduction and force reduction and greater settlement losses in the screw connection in these connection partners and a predominantly static load are not to be expected. Notes on problematic screw connections between two different solid materials, e.g. between steel materials and aluminum materials, does not give this document.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur kraftschlüssigen Verbindung von zwei Bauteilen aufzuzeigen sowie eine derart hergestellte Verbindung so zu verbessern, dass diese Verbindung möglichst über die gesamte Lebensdauer der Anbauteile die aufgeprägte Vorspannung bei minimalen Setzungsverlusten beibehält und eine selbsttätige, ungewollte Lockerung eines mit der Verbindung befestigten Anbauteiles im normalen Betrieb mit hoher Sicherheit verhindert wird.The invention is therefore an object of the invention to provide a method for frictional connection of two components and to improve a compound prepared in such a way that this compound as possible over the entire life of the attachments maintains the impressed bias with minimal settlement losses and an automatic, unwanted loosening of attached to the attachment attachment in normal operation with high security is prevented.

Diese Aufgabe wird für das Verfahren durch die im Anspruch 1 und für die Verbindung durch die im Anspruch 2 angegebenen Merkmale gelöst.This object is achieved for the method by the in claim 1 and for the compound by the features specified in claim 2.

Zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are described in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist nachstehend unter Bezugnahme auf die Zeichnung näher erläutert.An embodiment of the invention is explained below with reference to the drawings.

Die erfindungsgemäße kraftschlüssige Verbindung zwischen zwei Bauteilen besteht aus einem Trägerteil 1, einem Anbauteil 2, lösbaren Befestigungsmitteln 3 sowie mindestens einem Druckverteilstück 4. Im folgenden wird das Druckverteilstück 4 in der Einzahl verwendet, obwohl es auch mehrere sein können. Das Anbauteil 2 ist am Trägerteil 1 mittels der das Trägerteil 1 und das hinter ihm angeordnete Druckverteilstück 4 durchdringen Teils der Befestigungsmittel 3, insbesondere Schraube 3a, sowie des zugeordneten, haltenden Teils der Befestigungsmittels, insbesondere Mutter 3b, befestigt. Das Druckverteilstück 4 ist mit dem Trägerteil 1 verschweißt. Dabei ist es für die Spannungseinbringung und Haltbarkeit der Schraubverbindung besonders vorteilhaft, wenn das Druckverteilstück 4 erst nach Aufbringen einer vorgesehenen Vorspannkraft mit Hilfe der lösbaren Befestigungsmittel 3 mit dem Trägerteil 1 unter Spannung verschweißt wird. Das Druckverteilstück 4 verteilt die Kräfte aus der Vorspannung der Befestigungsmittel 3 und aus der betrieblichen Beanspruchung auf benachbarte Bauteile. Nach der Herstellung der Schweißnähte können die lösbaren Befestigungsmittel 3 gelöst und demontiert werden, wobei für diesen Zustand die Schweißnähte 8 am Druckverteilstück 4 anteilige Spannungen - aus der Rücknahme der Vorspannkräfte - erhalten.The non-positive connection according to the invention between two components consists of a carrier part 1, an attachment 2, releasable attachment means 3 and at least one pressure distribution 4. In the following, the pressure distribution 4 is used in the singular, although it may be several. The attachment 2 is on the support part 1 by means of the carrier part 1 and arranged behind it Druckverteilstück 4 penetrate part of the fastening means 3, in particular screw 3a, and the associated, holding part of the fastening means, in particular nut 3b, attached. The pressure distribution piece 4 is welded to the carrier part 1. It is particularly advantageous for the voltage input and durability of the screw when the Druckverteilstück 4 is welded only after application of a proposed biasing force by means of the releasable fastening means 3 with the support member 1 under tension. The Druckverteilstück 4 distributes the forces from the bias of the fastener 3 and the operational stress on adjacent components. After the production of the welds, the releasable attachment means 3 can be loosened and disassembled, for which state the welds 8 on the pressure distribution piece 4 proportional stresses - from the withdrawal of the preload forces - received.

Bei der Montage der vorgesehenen Bauteile, z. B. Gelenk, Kupplung etc. durch die lösbaren Befestigungsmittel 3 mit der planmäßig aufzubringenden Vorspannkraft werden die Spannungen in den Schweißnähten 8 wieder entsprechend vermindert. Dadurch erreichen die Schweißnähte 8 am Druckstück 4 ein hohes Potential an ertragbaren Spannungen aus betrieblichen Beanspruchungen.When mounting the intended components, eg. As joint, coupling, etc. by the releasable fastening means 3 with the scheduled applied biasing force, the stresses in the welds 8 are again reduced accordingly. As a result, the weld seams 8 on the pressure piece 4 reach a high potential of sustainable stresses from operational stresses.

Das Trägerteil 1 ist als Hohl- bzw. Hohlkammerprofil ausgebildet, das Stege 5 aufweist, die in unmittelbarer Nähe der lösbaren Befestigungsmittel 3 und parallel zum Schaft des durchdringenden Befestigungsmittels (Schraube 3a) angeordnet sind. Die Anordnung der Stege 5 in der unmittelbaren Nähe des lösbaren Befestigungsmittels 3 bewirken eine erhöhte Steifigkeit der Profile in diesem Bereich und ermöglichen das Aufbringen von höheren Vorspannkräften.The support member 1 is formed as a hollow or hollow chamber profile, the webs 5, which are arranged in the immediate vicinity of the releasable fastening means 3 and parallel to the shaft of the penetrating fastening means (screw 3a). The arrangement of the webs 5 in the immediate vicinity of the releasable fastener 3 cause increased stiffness of the profiles in this area and allow the application of higher biasing forces.

Durch diese Bauweise in Verbindung mit Schrauben großer Klemmlänge, insbesondere mit Dehnelementen (Dehnschrauben) werden im Betriebsfall die Setzungsempfindlichkeit und damit die Vorspannkraftverluste reduziert. Die Verbindung ist haltbarer, insbesondere bei hohen betrieblichen Beanspruchungen.Due to this design in conjunction with screws of large clamping length, in particular with expansion elements (expansion screws), the settlement sensitivity and thus the preload force losses are reduced in the case of operation. The compound is more durable, especially at high operating loads.

Das Druckverteilstück 4 besteht mindestens in der Schweißzone aus einem Werkstoff, der mit dem Trägerteil 1 verschweißbar ist. Vorzugsweise wird ein artgleicher Werkstoff verwendet.The pressure distribution piece 4 consists, at least in the welding zone, of a material which can be welded to the carrier part 1. Preferably, a material of the same material is used.

Das Druckverteilstück 4 kann weitere Versteifungsstege 6 zur Erhöhung der Steifigkeit aufweisen.The pressure distribution piece 4 may have further stiffening webs 6 for increasing the rigidity.

Das Druckverteilstück 4 ist in einer bevorzugten Ausführungsform topfartig ausgebildet. Es weist dabei umlaufende Versteifungsstege 6 im Randbereich auf.The pressure distribution piece 4 is pot-shaped in a preferred embodiment. It has circumferential stiffening webs 6 in the edge region.

Zwischen dem Druckverteilstück 4 und dem zugeordneten, krafteinleitenden Ende des lösbaren Befestigungsmittels 3 ist ein Druckstück 7, insbesondere aus dem Werkstoff Stahl, angeordnet.Between the Druckverteilstück 4 and the associated, force-introducing end of the releasable fastening means 3 is a pressure piece 7, in particular made of the material steel.

Besonders vorteilhaft ist der Gegenstand der Erfindung anzuwenden, wenn das Anbauteil 2 aus höherfestem Werkstoff als das Trägerteil 1 besteht. Dies ist der Fall, wenn Stahlteile z. B. Gelenke und/oder Kupplungsböcke an Aluminiumkonstruktionen belastbar und betriebssicher befestigt werden müssen.The object of the invention is particularly advantageous if the attachment 2 is made of a material of a higher strength than the carrier part 1. This is the case when steel parts z. B. joints and / or coupling brackets to aluminum structures must be able to be fixed and reliable.
