Abstract

The buffer arrangement is placed on one of the two components, e.g. the bonnet or tailgate. The initial tension between the two components is adjusted by a stop-piece (6) in the form of a washer for the buffer-head (5). The stop-piece has a thickness and or elasticity selected according to the required pre-tension, and is inserted between the buffer head and the other component (8). The buffer arrangement (4) is detachably fixed to the one component (1) by an insertion hole (3) and a bayonet attachment (17) before being automatically adjusted to the gap between the two components.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Anschlagpufferanordnung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for producing a stop buffer arrangement according to the preamble of claim 1.

Verfahren und Anordnungen dieses Aufbaues, wie sie aus der DE 40 11 186 C2 bekannt sind, bieten den großen Vorteil, daß die Anpassung der axialen Lage des Pufferkopfes der Pufferanordnung an den jeweiligen Spalt zwischen den beiden Bauteilen, also beispielsweise einer Heckklappe eines Kraftfahrzeugs und einem festen Aufbaubereich desselben, weitgehend selbsttätig erfolgt. Wie im einzelnen in der Druckschrift auseinandergesetzt, wird zu diesem Zweck eine Schraube in einer Spreizhülse in eine Position gebracht, in der sie auf die Hülse praktisch keine spreizende Wirkung ausübt; außerdem wird der Pufferkopf etwas aus einer die Spreizhülse aufnehmenden Hülse herausgezogen, so daß bei einem Schließvorgang der beiden Bauteile der Pufferkopf auf eine ihm zugeordnete Anschlagfläche an dem anderen Baute auftrifft und von dieser entsprechend dem Spalt zwischen den beiden Bauteilen zusammen mit der ungespreizten Spreizhülse etwas weiter in die diese umgebende Hülse hineinbewegt wird. Nach erneuter Trennung der beiden Bauteile, also beispielsweise nach Aufklappen der Heckklappe eines Kraftfahrzeugs, wird nunmehr die Spreizhülse durch weiteres Hineinschrauben der Schraube gespreizt, so daß sie axial fest in der sie umgebenden Hülse sitzt, und mittels eines Außengewindes auf dieser Hülse, das mit einer mit Befestigungsmitteln für die Pufferanordnung an dem einen Baute ausgerüsteten Innengewindehülse zusammenwirkt, wird der Pufferkopf wieder etwas herausbewegt, wodurch eine gewünschte Vorspannung zwischen den beiden Bauteilen in ihrer Schließstellung erzielt wird. Würde man auf eine derartige Vorspannung verzichten, so bestünde die Gefahr, daß auch bei einem voll funktionsfähigen Schloß zum Zusammenhalten der beiden Bauteile Klappergeräusche auftreten. Methods and arrangements of this structure, as known from DE 40 11 186 C2 are the great advantage that the adjustment of the axial position of the buffer head Buffer arrangement at the respective gap between the two components, that is for example a tailgate of a motor vehicle and a fixed body area the same, largely done automatically. As detailed in the publication apart, for this purpose a screw in an expansion sleeve in a Brought position in which it has practically no spreading effect on the sleeve; in addition, the buffer head becomes something from a sleeve receiving the expansion sleeve pulled out so that when the two components close, the buffer head opens a stop surface assigned to it strikes on and from the other building corresponding to the gap between the two components together with the unspread Expansion sleeve is moved a little further into the surrounding sleeve. After renewed Separation of the two components, for example after opening the tailgate one Motor vehicle, the expansion sleeve is now by further screwing the screw spread so that it sits axially firmly in the sleeve surrounding it, and by means of a External thread on this sleeve, which with a fastener for the Buffer arrangement cooperates on the inner thread sleeve equipped with a building, the buffer head is moved out again a little, creating a desired preload is achieved between the two components in their closed position. Would you like one dispense with such bias, there is a risk that even with a full functional lock to hold the two components together rattling noises occur.

Diese bekannte Anschlagpufferanordnung enthält also in der Pufferanordnung Funktionsteile sowohl für die Anpassung der axialen Lage des Pufferkopfes an die jeweilige Spaltweite als auch zur Einstellung einer gewünschten Vorspannung. Daraus resultiert ein relativ komplizierter, fertigungstechnisch schwer zu beherrschender Aufbau der Pufferanordnung. Insbesondere erfordert die Losung der beschriebenen beiden Teilaufgaben mit dieser einen Anordnung auch die Herstellung von Gewinden unterschiedlicher Steigungssinne.This known stop buffer arrangement thus contains functional parts in the buffer arrangement both for the adaptation of the axial position of the buffer head to the respective gap width also for setting a desired preload. This results in a relative complicated structure of the buffer arrangement that is difficult to master in terms of production technology. In particular, solving the two subtasks described with this requires one Arrangement also the production of threads of different pitch senses.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren unter Wahrung der Vorteile des Standes der Technik zu schaffen, das einen besonders einfachen, relativ robusten Aufbau der Pufferanordnung ermöglicht und sich durch eine einfache Einstellung von axialer Lage des Pufferkopfes und Vorspannung auszeichnet.The invention has for its object a generic method while preserving the advantages of the prior art to create a particularly simple, relative robust construction of the buffer arrangement enables and easy adjustment characterized by the axial position of the buffer head and preload.

Die erfindungsgemäße Losung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The solution to this problem according to the invention consists in the characteristic features of the main claim, advantageous embodiments of the invention describe the Subclaims.

Ein erstes wesentliches Merkmal der Erfindung gegenüber dem diskutierten Stand der Technik ist in der Trennung der Maßnahmen und Mittel zur Selbstanpassung der axialen Lage des Pufferkopfes an die jeweilige Spaltweite einerseits und zur Einstellung der jeweils erforderlichen Vorspannung andererseits zu sehen, eine Trennung, die dem heute üblichen Trend zur Zusammenfassung der Maßnahmen und Mittel zur Lösung verschiedener Aufgaben widerspricht. Daraus resultiert eine wesentliche Vereinfachung der Pufferanordnung insofern, als die die Spreizhülse umgebende Hülse als Außenhülse das äußerste Bauteil der Pufferanordnung bildet, also keine zusätzliche Außenhülse vorhanden ist, die über Gewinde mit einem Außengewinde auf der die Spreizhülse umgebenden Hülse kämmt. Demgemäß trägt die die Spreizhülse umgebende Hülse gemäß Anspruch 7 vorzugsweise auch Mittel zur Herstellung einer lösbaren Verbindung mit dem einen Bauteil, beispielsweise der Heckklappe eines Kraftfahrzeugs.A first essential feature of the invention compared to the discussed state of the Technology is in the separation of measures and means of self-adjustment of the axial Position of the buffer head on the respective gap width on the one hand and for setting the respective required bias on the other hand to see a separation that is common today Trend to summarize the measures and means to solve different Contradicts tasks. This results in a significant simplification of the Buffer arrangement insofar as the sleeve surrounding the expansion sleeve serves as the outer sleeve forms the outermost component of the buffer arrangement, so there is no additional outer sleeve is the thread with an external thread on the sleeve surrounding the expansion sleeve combs. Accordingly, the sleeve surrounding the expansion sleeve according to claim 7 preferably also means for producing a releasable connection with the one component, for example the tailgate of a motor vehicle.

Ein weiteres wesentliches Merkmal der Erfindung ist darin zu sehen, daß zur Vorspannungseinstellung ein sehr einfaches Teil Einsatz findet, nämlich ein Anschlagteil entsprechender Stärke bzw. Dicke und Elastizität, das nach Durchführung der Selbstanpassung der axialen Lage des Pufferkopfes an die jeweilige Spaltweite entweder an dem anderen Bauteil, also beispielsweise dem Öffnungsrahmen eines Fahrzeug-Kofferraumes, oder stirnseitig am Pufferkopf mit einfachen, an sich bekannten Mitteln und Handgriffen festgelegt wird.Another essential feature of the invention is the fact that for Bias adjustment is a very simple part, namely a stop part appropriate strength or thickness and elasticity, which after performing the Self-adjustment of the axial position of the buffer head to the respective gap width either the other component, for example the opening frame of a vehicle trunk, or on the face of the buffer head with simple means known per se and Handles is set.

Betrachtet man zunächst Figur 1, so erkennt man bei 1 den hinteren Bereich einer Kraftfahrzeug-Heckklappe, deren Aufbau im einzelnen nicht interessiert. In ihrem unteren Blech 2 befindet sich eine Öffnung 3, die später anhand Figur 3 noch zu erläutern ist und die zum teilweisen Durchstecken der Pufferanordnung 4 dient. Die Pufferanordnung 4 weist den elastischen Pufferkopf 5 auf, der nach Komplettierung der Anschlagpufferanordnung mit Vorspannung auf der pilz- oder stopfenartig ausgebildeten, als Anschlagteil dienenden Scheibe 6 aufliegt, die in an sich bekannter Weise in dem Blindniet 7 am Aufbaurahmen 8 festgelegt ist.If one looks first at FIG. 1, the rear area of one can be seen at 1 Motor vehicle tailgate, the structure of which is of no interest. In her lower one Sheet 2 is an opening 3, which will be explained later with reference to Figure 3 and serves to partially insert the buffer arrangement 4. The buffer arrangement 4 has the elastic buffer head 5, which after completing the stop buffer assembly with Preload on the mushroom or stopper-shaped, serving as a stop part Disc 6 rests, which, in a manner known per se, in the blind rivet 7 on the mounting frame 8 is set.

Gemäß Figur 2 enthält die Pufferanordnung 4 als wesentliche Bestandteile außer dem Pufferkopf 5 die diesen tragende Spreizhülse 9 mit dem äußeren Rastprofil 10, die in der Außenhülse 11 mit dem inneren Rastprofil 12 geführt ist. Die Außenhülse 11 ist, wie noch anhand der Figuren 4 und 5 erläutert wird, mit Mitteln zur lösbaren Befestigung an dem Blech 2 versehen. Diese Befestigung erfolgt, wie ebenfalls noch erläutert wird, unter Ausnutzung der Elastizität der Dichtung 13.According to Figure 2, the buffer arrangement 4 contains as essential components besides that Buffer head 5, this expansion sleeve 9 with the outer locking profile 10, which in the Outer sleeve 11 is guided with the inner locking profile 12. The outer sleeve 11 is, as before is explained with reference to Figures 4 and 5, with means for releasable attachment to the Provide sheet 2. This attachment takes place, as will also be explained below Exploiting the elasticity of the seal 13.

Zunächst wird - bei geöffneter Heckklappe - die Schraube 14 etwas aus der Spreizhülse 9 herausgedreht, so daß deren Spreizung so weit aufgehoben ist, daß sie zwar nicht aus der Außenhülse 11 herabfällt, aber doch in ihr verschoben werden kann. Der Pufferkopf 5 wird relativ weit nach unten herausgezogen, und die Heckklappe 1 wird geschlossen, wobei jetzt die Scheibe 6 noch nicht eingesetzt ist. Das bedeutet, daß der Pufferkopf 5 mit seiner nach unten weisenden Auflagefläche zur Auflage auf dem Blech 15 des Rahmens 8 kommt. Er wird demgemäß in eine Position nach oben verschoben, die dem jeweiligen Spalt zwischen den beiden Bauteilen 1 und 8 entspricht. Diese Lage ist strichpunktiert bei 5' in Figur 2 angedeutet. Nunmehr wird die Schraube 14 tiefer in die Spreizhülse 9 hineingeschraubt, so daß diese gespreizt wird und ihr Rastprofil 10 mit dem Rastprofil 12 der Außenhülse 11 zusammenwirkt: Die gefundene axiale Lage des Pufferkopfes 5 wird fixiert.First, with the tailgate open, the screw 14 is somewhat removed from the expansion sleeve 9 unscrewed so that their spread is canceled so far that it does not come out of the Outer sleeve 11 falls, but can still be moved in it. The buffer head 5 is pulled out relatively far down, and the tailgate 1 is closed, being now the disc 6 has not yet been inserted. This means that the buffer head 5 with its after bottom-facing bearing surface comes to rest on the sheet 15 of the frame 8. He is accordingly shifted up into a position that the respective gap between corresponds to the two components 1 and 8. This position is dash-dotted at 5 'in Figure 2 indicated. Now the screw 14 is screwed deeper into the expansion sleeve 9, so that it is spread and its locking profile 10 with the locking profile 12 of the outer sleeve 11th interacts: The found axial position of the buffer head 5 is fixed.

Erst jetzt wird zur Erzeugung einer vorgegebenen Vorspannung die Scheibe 6 eingesetzt, so daß beim erneuten Schließen der Heckklappe 1 der Pufferkopf 5, wie in Figur 1 gezeigt, auf der Scheibe 6 aufliegt. Der Selbstjustierung der axialen Lage des Pufferkopfes 5 in Abhängigkeit von der jeweiligen Spaltweite zwischen den Bauteilen 1 und 8 einerseits und der Herstellung und Einstellung einer vorgegebenen Vorspannung andererseits dienen also bei der Erfindung unterschiedliche Maßnahmen und Einrichtungen, nämlich einerseits die Pufferanordnung 4 gemäß Figur 2 und andererseits die Scheibe 6 in Figur 1.Only now is the disc 6 used to generate a predetermined preload, so that when the tailgate 1 is closed again, the buffer head 5, as shown in FIG. 1, rests on the disc 6. The self-adjustment of the axial position of the buffer head 5 in Dependence on the respective gap width between components 1 and 8 on the one hand and the production and setting of a predetermined bias on the other hand serve in the invention different measures and facilities, namely the one hand Buffer arrangement 4 according to FIG. 2 and on the other hand the disk 6 in FIG. 1.

Zur Erzielung einer besonders einfachen lösbaren Verbindung der Pufferanordnung 4 dem Blech 2 der Heckklappe 1 dient heckklappenseitig die ein Durchstecken der Pufferanordnung 4 bei einer vorbestimmen Umfangsausrichtung derselben zulassende Öffnung oder Ausnehmung 3, die zwei Paare sich jeweils diametral gegenüberliegender radialer Fortsätze 16 und 17 aufweist, die in diesem Ausführungsbeispiel einen Winkel von 90° gegeneinander einschließen. Wie ersichtlich, haben die Fortsätze 16 eine größere Umfangserstreckung als die Fortsätze 17.To achieve a particularly simple detachable connection of the buffer arrangement 4 the Sheet 2 of the tailgate 1 is used on the tailgate side to insert the Buffer arrangement 4 with a predetermined circumferential orientation of the same Opening or recess 3, the two pairs each diametrically opposite has radial extensions 16 and 17, which in this embodiment has an angle of Include 90 ° against each other. As can be seen, the extensions 16 have a larger one Extent of extent than the extensions 17.

Die Außenhülse der Pufferanordnung 4 trägt gemäß den Figuren 4 und 5 in gleicher Anordnung und Auslegung zwei Paare radialer Rastfortsätze 18 und 19, die mit den radialen Fortsätzen 16 und 17 des Lochbildes gemäß Figur 3 zusammen eine bajonettverschlußartige Halterung für die Pufferanordnung 4 bilden.The outer sleeve of the buffer arrangement 4 carries according to the figures 4 and 5 in the same Arrangement and layout of two pairs of radial latching extensions 18 and 19 with the radial Extensions 16 and 17 of the hole pattern according to Figure 3 together a Form bayonet-type holder for the buffer assembly 4.

Betrachtet man nun die Figuren 6 und 7, so ist gemäß dem Pfeil 20 die Pufferanordnung 4 durch die Ausnehmung 3 hindurchgesteckt, bis sie mit ihrer Dichtung 13 (nur in den Figuren 4 und 5 gezeichnet) auf der Oberseite des Bleches 2 aufliegt. Während die in Umfangsrichtung kürzeren Rastfortsätze 19 in Richtung nach oben weisende symmetrische Profile 22 tragen, sind die entsprechenden Profile 23 der Rastfortsätze 18 größerer Umfangserstreckung praktisch nur einseitig abgeschrägt. Es kann zweckmäßig sein, das Profil 22 der Rastfortsätze 19 etwas höher auszuführen, um die nun erfolgende Schwenkbewegung der Pufferanordnung 4 gemäß den Figuren 8 und 9 im Bereich der Rastfortsätze 18 zu erleichtern.If one now considers FIGS. 6 and 7, the buffer arrangement 4 is according to arrow 20 inserted through the recess 3 until it with its seal 13 (only in the figures 4 and 5 drawn) rests on the top of the sheet 2. While the in Circumferential direction shorter latching extensions 19 in the upward-pointing symmetrical Wear profiles 22, the corresponding profiles 23 of the catch extensions 18 are larger Circumferential extent practically only beveled on one side. It may be appropriate Profile 22 of the latching extensions 19 to execute a little higher, in order to take place now Swiveling movement of the buffer arrangement 4 according to FIGS. 8 and 9 in the area of Latching processes 18 to facilitate.

Diese Schwenkbewegung findet gemäß den Figuren 10 und 11 dann ihr Ende, wenn die Profile 23 der

Figure 00050001
längeren" Rastfortsätze 18 eingefallen sind in die kürzeren" Fortsätze 17 der Durchstecköffnung 3. Unter der Wirkung der elastischen Dichtung 13 (Figuren 4 und 5), die die Pufferanordnung gas- und wasserdicht machen, erfolgt nun die Arreterierung der Pufferanordnung 4 in Umfangsrichtung. Diese Arretierung kann jedoch relativ leicht aufgehoben werden, nämlich durch Druck auf den Pufferkopf 5 und Verschwenken der Pufferanordnung 4 in den Figuren 10 und 11 im Uhrzeigersinn (von unten betrachtet).This pivoting movement ends according to FIGS. 10 and 11 when the profiles 23 of the
Figure 00050001
longer "latching extensions 18 have occurred in the shorter "extensions 17 of the push-through opening 3. Under the action of the elastic seal 13 (FIGS. 4 and 5), which make the buffer arrangement gastight and watertight, the buffer arrangement 4 is now locked in the circumferential direction. However, this locking can be released relatively easily, namely by pressing on the buffer head 5 and pivoting the buffer arrangement 4 in Figures 10 and 11 clockwise (viewed from below).

In dem Ausführungsbeispiel nach Figur 12 ist die Pufferanordnung 30 ebenso aufgebaut wie die Pufferanordnung 4 in den früheren Figuren mit dem einzigen Unterschied, daß der Pufferkopf 31 stirnseitig mit der profilierten Ausnehmung 32 zum Einknöpfen des Anschlagteils 33 versehen ist, das die Scheibe 6 ersetzt und wie diese erst nach erfolgter Selbstanpassung der Pufferanordnung 30 an die jeweilige Spaltweite festgelegt wird. Diese Konstruktion vermeidet also Maßnahmen am Rahmen 34 zur Festlegung eines Anschlagteils.In the exemplary embodiment according to FIG. 12, the buffer arrangement 30 is constructed in the same way as the buffer arrangement 4 in the previous figures with the only difference that the Buffer head 31 on the end face with the profiled recess 32 for buttoning the Stop part 33 is provided, which replaces the disc 6 and how this only after Self-adaptation of the buffer arrangement 30 to the respective gap width is determined. This Construction thus avoids measures on the frame 34 for determining a Stop part.

Damit gibt die Erfindung eine konstruktiv einfache und herstellungsmäßig leicht beherrschbare Lösung des Problems der Schaffung einer Anschlagpufferanodnung mit Möglichkeiten zur Selbstanpassung an die jeweilige Spaltweite und Einstellung einer vorgegebenen Vorspannung.Thus, the invention is structurally simple and easy to manufacture manageable solution to the problem of creating a bumper buffer arrangement Possibilities for self-adaptation to the respective gap width and setting one predetermined preload.
