Description

Die Erfindung betrifft eine Abstützauflage zum geführten Ansetzen einer Ausziehvorrichtung an einer in einem Motorgehäuse angeordneten Injektordüse, mit einem Basiselement, an dem die Ausziehvorrichtung führbar ist, am Basiselement jeweils über eine Drehachse drehbar angeordneten Tragarmen und zumindest drei, relativ zum Basiselement bewegbaren und festlegbaren Abstützfüßen, über die die Abstützauflage am Motorgehäuse abstützbar ist, wobei an jedem Tragarm wenigstens einer der Abstützfüße angeordnet und mit diesem Tragarm um dessen Drehachse drehbar gelagert ist. Weiters betrifft die Erfindung eine Demontagevorrichtung zum Demontieren einer Injektordüse aus einem Motorgehäuse, mit einer Abstützauflage und einer an der Injektordüse ansetzbaren Ausziehvorrichtung.The invention relates to a Abstützauflage for guided application of an extractor to a arranged in a motor housing injector, with a base member on which the puller is feasible, on the base member each rotatable about a rotation axis arranged support arms and at least three, relative to the base member movable and fixable outriggers, over which the Abstützauflage on the motor housing can be supported, being arranged on each support arm at least one of the support feet and is rotatably mounted with this support arm about its axis of rotation. Furthermore, the invention relates to a disassembly device for disassembling an injector nozzle from a motor housing, with a Abstützauflage and attachable to the injector nozzle extractor.

Bei Problemen mit Motoren - insbesondere Fahrzeugmotoren - liegt oftmals eine Fehlerquelle im Bereich der Injektordüsen. Diese Injektordüsen sind in speziellen Ausnehmungen im Motorgehäuse eingesteckt und stehen mit der Düsenspitze in eine Brennkammer im Motorgehäuse. Durch Einspritzung von Brennstoff über die Einspritzdüse erfolgt in der Brennkammer eine Zündung. Bei Schäden in den Injektordüsen ist ein Austauschen der Injektordüsen oftmals relativ schwierig, da diese aufgrund von Korrosion und Ähnlichem relativ fest im Motorgehäuse festsitzen und nur mit hohem Kraftaufwand aus dem Motorgehäuse gezogen werden können. Um dies zu bewerkstelligen, sind diverse Demontagevorrichtungen bereits seit Jahren bekannt (siehe beispielsweise AT 007 605 U1 und DE 20 2010 009 355 U1 ).Problems with engines - especially vehicle engines - often cause a source of error in the area of the injector nozzles. These injector nozzles are inserted in special recesses in the motor housing and stand with the nozzle tip in a combustion chamber in the motor housing. By injecting fuel through the injector takes place in the combustion chamber ignition. In the case of damage in the injector nozzles, replacement of the injector nozzles is often relatively difficult, since they are relatively firmly stuck in the motor housing due to corrosion and the like and can only be pulled out of the motor housing with great force. To accomplish this, various disassembly devices have been known for years (see, for example AT 007 605 U1 and DE 20 2010 009 355 U1 ).

Ein generelles Problem bei Demontagevorrichtungen besteht dahingehend, wie und wo eine Abstützung der Demontagevorrichtung am Motorgehäuse erfolgt. Je weiter sich dabei eine Injektordüse im Motorgehäuse "versteckt" und schlecht angreifbar ist, desto schwieriger ist das Ansetzen einer Demontagevorrichtung sowie das Abstützen dieser Demontagevorrichtung.A general problem with disassembly devices is how and where the disassembly device is supported on the motor housing. The further an injector nozzle "hides" in the motor housing and is difficult to attack, the more difficult it is to attach a dismantling device and to support this dismantling device.

Eine stabile Lösung für dieses Problem wird in der EP 2 163 347 A2 gezeigt. Dabei besteht eine Abstützauflage bzw. ein Träger aus einer Quertraverse und aus entlang dieser Quertraverse verschiebbaren und an der Quertraverse festlegbaren Stellschienen, die wiederum über Stützbolzen am Zylinderkopf bzw. Motorgehäuse aufliegen und den Träger bzw. die Abstützauflage abstützen. An der dadurch abgestützten und vom Motor beabstandeten Quertraverse wird dann eine Ausziehvorrichtung mit einer Zugstange und weiteren dafür benötigten Bestandteilen angelegt, und die Zugstange wird mit der Injektordüse verbunden. Dann wird die Kraft auf die Ausziehvorrichtung aufgebracht und die in Ausziehrichtung wirkende Kraft auf die Injektordüse wird durch Abstützung über die Quertraverse, die Stellschienen und die Stützbolzen auf das Motorgehäuse weitergeleitet.A stable solution to this problem will be in the EP 2 163 347 A2 shown. In this case, there is a Abstützauflage or a carrier of a crossbeam and displaceable along this crossbeam and fixable on the crossmember rails, which in turn rest on support bolts on the cylinder head or motor housing and support the carrier or the Abstützauflage. At the by supported and spaced from the engine cross-beam then a puller with a pull rod and other components required for it is applied, and the pull rod is connected to the injector. Then the force is applied to the extractor and the force acting in the pull-out direction on the injector nozzle is passed by support on the cross-beam, the guide rails and the support bolts on the motor housing.

Nachteilig bei dieser Ausführung ist, dass die beiden Stützbolzen bzw. Abstützfüße an einer Stellschiene (Tragarm) immer nur abhängig voneinander im Bereich des Motorgehäuses angebracht werden können. Das heißt, wenn ein Abstützfuß näher an der Injektordüse am Motorgehäuse angesetzt wird, ist der jeweils andere Stützbolzen zwangsweise weiter entfernt von der Injektordüse. Da ein stabiler Sitz der Abstützauflage bzw. des Trägers am Motorgehäuse hauptsächlich mit zumindest drei Abstützfüßen bzw. Stützbolzen erreicht werden kann, sind die Einsatzmöglichkeiten dieser bekannten Demontagevorrichtung beschränkt und nicht bei jedem Motor gleich gut bzw. bei manchen Motoren gar nicht verwendbar.A disadvantage of this design is that the two support bolts or support feet on a control rail (support arm) can only ever be mounted depending on each other in the range of the motor housing. That is, when a support foot is attached closer to the injector nozzle on the motor housing, the respective other support bolt is forcibly further away from the injector nozzle. Since a stable fit of the Abstützauflage or the support on the motor housing mainly with at least three Abstützfüßen or support bolts can be achieved, the possible applications of this known disassembly device are limited and not equally good for each engine or even unusable in some engines.

Deswegen betrifft die Erfindung weiters eine Abstützauflage, bei der jeder der zumindest drei Abstützfüße unabhängig von den jeweils anderen zumindest zwei Abstützfüßen mit dem Tragarm an dem er angeordnet ist um dessen Drehachse drehbar gelagert ist. Das heißt, jeder der drei Abstützfüße ist autark von den anderen an einem Ansetz- bzw. Abstützpunkt am Motorgehäuse ansetzbar. Dadurch kann eine Abstützauflage besser an die unterschiedlich gestalteten Motorgehäuse verschiedener Hersteller angesetzt werden.Therefore, the invention further relates to a Abstützauflage, wherein each of the at least three Abstützfüße is independent of the respective other at least two Abstützfüßen with the support arm on which it is arranged rotatably mounted about its axis of rotation. That is, each of the three outriggers is self-sufficient attachable from the other at a Ansetz- or support point on the motor housing. As a result, a Abstützauflage be better attached to the differently designed motor housing from different manufacturers.

Eine derartige gattungsbildende Abstützauflage geht aus der DE 20 2010 011 341 U1 hervor, bei der die einzelnen Arme drehbar um ein zentrales Element schwenkbar gelagert sind. Die Abstützfüße wiederum sind an den Armen verschiebbar gelagert.Such a generic Abstützauflage goes out of the DE 20 2010 011 341 U1 in which the individual arms are rotatably mounted pivotably about a central element. The support feet in turn are slidably mounted on the arms.

Die Aufgabe der vorliegenden Erfindung liegt daher darin, eine gegenüber dem Stand der Technik verbesserte Abstützauflage für eine Ausziehvorrichtung einer Demontagevorrichtung zu schaffen. Insbesondere sollen die Einsatzmöglichkeiten der Abstützauflage nicht aufgrund der Besonderheiten bei Motoren unterschiedlicher Motorenhersteller eingeschränkt sein.The object of the present invention is to provide a comparison with the prior art improved Abstützauflage for an extractor of a disassembly device. In particular, the possible uses of Abstützauflage should not be limited due to the peculiarities of engines of different engine manufacturers.

Dies wird für eine Abstützauflage mit den Merkmalen des Oberbegriffes von Anspruch 1 dadurch erreicht, dass jeder Tragarm verschiebbar am Basiselement angeordnet ist.This is achieved for a Abstützauflage with the features of the preamble of claim 1, characterized in that each support arm is slidably mounted on the base member.

Grundsätzlich soll nicht ausgeschlossen sein, dass an einem Tragarm mehrere Abstützfüße angeordnet sind. Bevorzugt ist allerdings vorgesehen, dass nur ein einziger Abstützfuß pro Tragarm vorgesehen ist. Anders ausgedrückt ist bevorzugt vorgesehen, dass nur in einer einzigen, von jeder Drehachse radial wegführenden Richtung jeweils ein Abstützfuß an jedem Tragarm angeordnet ist.In principle, it should not be ruled out that several support feet are arranged on a support arm. However, it is preferably provided that only one support foot is provided per support arm. In other words, it is preferably provided that in each case one support foot is arranged on each support arm only in a single, radially away from each axis of rotation direction.

Bei einer Ausführung können die Abstützfüße relativ zum Tragarm in Richtung Basiselement und von diesem weggeschoben werden. Es ist weiters bevorzugt vorgesehen, dass jeder der drei Abstützfüße über einen eigenen, ihm zugeordneten Tragarm drehbar am Basiselement gelagert ist.In one embodiment, the Abstützfüße can be pushed relative to the support arm in the direction of the base element and from this. It is further preferably provided that each of the three support feet is rotatably supported on the base member via its own, associated with him support arm.

Um möglichst vielfältige Einsatzmöglichkeiten der erfindungsgemäßen Abstützauflage zu erreichen, ist bevorzugt vorgesehen, dass im Basiselement mehrere, vorzugsweise acht, vorzugsweise regelmäßig, voneinander beabstandete Bohrungen ausgebildet sind, an denen jeweils ein Tragarm über eine Befestigungsvorrichtung befestigbar ist. Fertigungstechnisch vorteilhaft ist ein Basiselement mit zehn Bohrungen. Dadurch können verschiedenste, vom Basiselement unterschiedlich weit entfernte Ansetzpunkte am Motorgehäuse erreicht werden. Diesbezüglich soll aber grundsätzlich nicht ausgeschlossen werden, dass im Basiselement keine Bohrungen sondern Fortsätze ausgebildet sind, an denen die Tragarme über eine Befestigungsvorrichtung befestigt werden können.In order to achieve the widest possible range of possible uses of the Abstützauflage invention, it is preferably provided that in the base element a plurality, preferably eight, preferably regularly, spaced bores are formed, to each of which a support arm via a fastening device can be fastened. Manufacturing technology advantageous is a base element with ten holes. As a result, a variety of different from the base element far distant attachment points can be achieved on the motor housing. In this regard, but should not be ruled out in principle that in the base member no holes but extensions are formed, to which the support arms can be attached via a fastening device.

Ein besonders bevorzugtes Ausführungsbeispiel der vorliegenden Erfindung kann vorsehen, dass zumindest ein, vorzugsweise jeder, Abstützfuß längenverstellbar ist. Dadurch ist ein Anpassen an unterschiedliche Höhen und Abstände zu unterschiedlichen Ansetzpunkten am Motorgehäuse ermöglicht. Die Ansetzpunkte müssen somit nicht auf einer Ebene liegen.A particularly preferred embodiment of the present invention may provide that at least one, preferably each, support foot is adjustable in length. This makes it possible to adapt to different heights and distances to different attachment points on the motor housing. The attachment points must therefore not be on one level.

Schutz wird auch begehrt für eine Demontagevorrichtung zum Demontieren einer Injektordüse aus einem Motorgehäuse, mit einer Abstützauflage nach einem der Ansprüche 1 bis 5 und einer an der Injektordüse ansetzbaren Ausziehvorrichtung. Bevorzugt kann dabei vorgesehen sein, dass im Basiselement der Abstützauflage eine, vorzugsweise zentrale, Durchtrittsöffnung für die Ausziehvorrichtung ausgebildet ist. Am Rande dieser Durchtrittsöffnung kann die Ausziehvorrichtung geführt anliegen.Protection is also desired for a disassembly device for disassembling an injector nozzle from a motor housing, with a Abstützauflage according to one of claims 1 to 5 and an attachable to the injector nozzle extractor. It can preferably be provided that in the base element of the Abstützauflage a, preferably central, passage opening is formed for the extraction device. At the edge of this passage opening the extractor can rest guided.

Um für eine Demontagevorrichtung mit einer Abstützauflage in Form eines Basiselementes mit Abstützfüßen auch ein Demontieren von gegenüber dem Basiselement schrägen (also nicht normal ausgerichteten) Injektordüsen zu ermöglichen, kann vorgesehen sein, dass die Ausziehvorrichtung über eine eine Durchtrittsöffnung für die Ausziehvorrichtung aufweisende Positioniervorrichtung am Basiselement geführt ist, wobei die Positioniervorrichtung einen konvex-kugelförmigen Oberflächenbereich aufweist, über den die Positioniervorrichtung drehgelenkig verschiebbar am Basiselement anlegbar ist. Dadurch ist das Anlegen der Ausziehvorrichtung am Führungselement nicht mehr in eine einzige Richtung begrenzt, sondern kann durch Drehen bzw. Verschieben der Positioniervorrichtung entlang seiner konvex-kugelförmigen Oberfläche entsprechend an die schief gestellte Injektordüse herangeführt werden.In order to allow for a disassembly device with a Abstützauflage in the form of a base element with Abstützfüßen also disassembling relative to the base element oblique (ie not normally aligned) injector nozzles, it can be provided that the extraction device via a passage opening for the extractor having positioning on the base element is, wherein the positioning device has a convex-spherical surface area over which the positioning device is pivotally displaceable on the base element can be applied. As a result, the application of the extraction device on the guide element is no longer limited in a single direction, but can be brought by turning or moving the positioning along its convex-spherical surface according to the obliquely Asked injector.

Bevorzugt kann diesbezüglich vorgesehen sein, dass das Basiselement ein um die Durchtrittsöffnung angeordnetes Ringelement aufweist, an dem die Positioniervorrichtung anlegbar ist, wobei besonders bevorzugt das Ringelement einen konkav-kugelförmigen Oberflächenbereich aufweist und der konkav-kugelförmige Oberflächenbereich des Ringelements und der konvex-kugelförmige Oberflächenbereich der Positionsvorrichtung aneinander anliegend zueinander - unter Verstellung bzw. Bewegung der Längsachse der Ausziehvorrichtung um den gedachten Mittelpunkt des konvex-kugelförmigen Oberflächenbereichs - verschiebbar sind. Durch diese Ausführung bildet die Positioniervorrichtung mit dem Ringelement eine Art Kugelgelenk, wobei die Positioniervorrichtung den Kugelgelenkskopf und das Ringelement die Gelenkspfanne bildet. Die Längsachse der Ausziehvorrichtung führt immer durch den Mittelpunkt des konvex-kugelförmigen Bereichs der Positioniervorrichtung. Das Ringelement - insbesondere dessen konkav-kugelförmige Oberfläche - kann auch einstückig mit dem Basiselement ausgebildet sein.Preferably, it can be provided in this regard that the base element has a ring element arranged around the passage opening, on which the positioning device can be applied, the ring element particularly preferably having a concave-spherical surface area and the concave-spherical surface area of the ring element and the convex-spherical surface area of the ring element Positional device adjacent to each other - under adjustment or movement of the longitudinal axis of the extraction device to the imaginary center of the convex-spherical surface area - are displaced. With this design, the positioning device forms a kind of ball joint with the ring element, wherein the positioning device forms the ball joint head and the ring element forms the joint socket. The longitudinal axis of the extractor always passes through the center of the convex-spherical portion of the positioning device. The ring element - in particular its concave-spherical surface - may also be formed integrally with the base element.

Fig. 1 zeigt ein Motorgehäuse 3 (z.B. eines Common Rail Dieselmotors), wobei an einer Injektordüse 4 eine Ausziehvorrichtung 2 (Hubvorrichtung) angesetzt ist. Diese Ausziehvorrichtung besteht dabei im Wesentlichen aus der Komponente 19 (die vorzugsweise ein Hydraulik-Hohlkolbenzylinder ist), der Ausziehstange 20 und der Ansetzvorrichtung 21, mit der die Ausziehvorrichtung 2 am Kopf der Injektordüse 4 angesetzt bzw. angeschraubt ist (die Ausziehstange 20 kann auch direkt an der Injektordüse 4 angesetzt bzw. angeschraubt werden). Fig. 1 shows a motor housing 3 (for example, a common rail diesel engine), wherein at an injector nozzle 4 an extractor 2 (lifting device) is attached. This extraction device consists essentially of the component 19 (which is preferably a hydraulic hollow piston cylinder), the pull-out rod 20 and the attachment device 21, with which the puller 2 is attached or screwed to the head of the injector 4 (the pull-out rod 20 can also directly attached to the injector nozzle 4 or screwed).

Um für das Herausziehen der festgeklemmten Injektordüse 4 eine Abstützung der Ausziehvorrichtung 2 zu ermöglichen, ist eine Abstützauflage 1 für die Ausziehvorrichtung 2 am Motorgehäuse 3 aufgesetzt. Diese Abstützauflage 1 weist als wesentliche Bestandteile ein Basiselement 5 mit einer Durchtrittsöffnung 13 für die Ausziehvorrichtung 2, drei am Basiselement 5 drehbar und verschiebbar festgesetzte Tragarme 6 und drei an den Tragarmen 6 festlegbare Abstützfüße 7 auf. Diese drei Abstützfüße 7 sind dabei unabhängig bzw. autark voneinander an unterschiedlichen Abstützpunkten 22 auf dem Motorgehäuse 3 aufsetzbar bzw. festlegbar. Wenn nun eine in Ausziehrichtung wirkende Kraft auf die Komponente 19 aufgebracht wird, erfolgt eine Abstützung über die Abstützauflage 1 am Motorgehäuse 3. Die Komponente 19 könnte im einfachsten Fall als Mutter ausgebildet sein, wobei durch Drehung dieser am Basiselement 5 anliegenden Mutter eine Bewegung der Ausziehstange 20 in Ausziehrichtung erfolgt.In order to allow for the extraction of the clamped injector nozzle 4 a support of the puller 2, a Abstützauflage 1 is set for the puller 2 on the motor housing 3. This Abstützauflage 1 has as essential components a base member 5 with a passage opening 13 for the puller 2, three rotatably and slidably fixed to the base member 5 fixed support arms 6 and three attachable to the support arms 6 support feet 7. These three support feet 7 are independently or independently of each other at different support points 22 on the motor housing 3 can be placed or fixed. Now, if a force acting in the pull-out direction is applied to the component 19, a support via the Abstützauflage 1 on the motor housing 3. The component 19 could be formed in the simplest case as a nut, wherein by rotation of this voltage applied to the base member 5 nut movement of the pull-out 20 takes place in the direction of withdrawal.

Durch die in Fig. 1 dargestellte Ausführung der Abstützfüße 7 und der Tragarme 6 ist eine gegenüber dem Stand der Technik vielseitigere und bei unterschiedlichen Motorausführungen einsetzbare Abstützauflage 1 für Demontagevorrichtungen 12 geschaffen.By the in Fig. 1 illustrated embodiment of the Abstützfüße 7 and the support arms 6 is compared to the prior art more versatile and usable in different engine versions Abstützauflage 1 for disassembly devices 12 created.

Fig. 2 zeigt eine Explosionsdarstellung einer Abstützauflage 1. Dabei sind im Basiselement 5 mehrere Bohrungen 8 ausgebildet, über die vom Mechaniker individuell über Befestigungsvorrichtungen 9 die Tragarme 6 angebracht werden können. Eine Befestigungsvorrichtung 9 weist dabei eine Gewindestange 24, eine Beilagscheibe 25, eine Mutter 26 und einen Gleitschuh 10 auf, wobei diese durch Festdrehen der Mutter 26 nach Durchführen der Gewindestange 24 durch eine Bohrung 8 und nach Festdrehen der Mutter 26 am Basiselement 5 festlegbar ist. Der Gleitschuh 10 ist in einer im Tragarm 6 ausgebildeten Verschiebebahn 11 geführt. Die Verschiebebewegung ist einerseits durch die Ausbildung der Verschiebebahn 11 und andererseits durch ein einschraubbares Begrenzungselement 23 begrenzt. Der Tragarm 6 ist nach seinem Anbringen am Basiselement 5 über die Befestigungsvorrichtung 9 um die Drehachse D drehbar und entlang des Gleitschuhs 10 verschiebbar. Erst mit dem Festdrehen der Mutter 26 wird eine stabile Festlegung des Tragarms 6 gegenüber dem Basiselement 5 erreicht. Im Tragarm 6 selbst befindet sich am von der Befestigungsvorrichtung 9 abgewandten Ende eine Durchtrittsöffnung 32 für einen Abstützfuß 7. Dieser Abstützfuß 7 besteht aus den Komponenten 27, 28, 29, 30 und 31. Eine Längenveränderung dieses Abstützfußes 7 ist durch Drehen und unterschiedliches Festlegen der einzelnen Komponenten zueinander möglich. Weiters weist die Abstützauflage 1 eine Positioniervorrichtung 15 mit einer Durchtrittsöffnung 14 sowie ein Ringelement 17 auf. Die Positioniervorrichtung 15 liegt dabei über seinen konvex-kugelförmigen Oberflächenbereich 16 am konkav-kugelförmigen Oberflächenbereich 18 des Ringelementes 17 auf, welches wiederum selbst plan auf dem Basiselement 5 aufliegt. Fig. 2 shows an exploded view of a Abstützauflage 1. In the base element 5 a plurality of holes 8 are formed, on the mechanic individually via fastening devices 9, the support arms 6 can be attached. A fastening device 9 in this case has a threaded rod 24, a washer 25, a nut 26 and a shoe 10, which can be fixed by tightening the nut 26 after passing the threaded rod 24 through a bore 8 and after tightening the nut 26 on the base member 5. The shoe 10 is guided in a trained in the support arm 6 slide track 11. The displacement movement is limited on the one hand by the formation of the sliding track 11 and on the other hand by a screw-in limiting element 23. The support arm 6 is rotatable after its attachment to the base member 5 via the fastening device 9 about the rotation axis D and along the slide shoe 10. Only with the tightening of the nut 26, a stable fixing of the support arm 6 relative to the base element 5 is achieved. In the support arm 6 itself is located at the end remote from the fastening device 9 end a passage opening 32 for a support foot 7. This support foot 7 consists of the components 27, 28, 29, 30 and 31. A change in length of this support foot 7 is by turning and different setting the individual components to each other possible. Furthermore, the Abstützauflage 1 a positioning device 15 with a passage opening 14 and a ring member 17. The positioning device 15 rests on its convex-spherical surface area 16 on the concave-spherical surface area 18 of the ring element 17, which in turn rests flat on the base element 5 itself.

Die Abstützauflage 1 im zusammengebauten Zustand ist in Fig. 3 ersichtlich, wobei gemäß diesem Ausführungsbeispiel das Basiselement 5 nicht kreisförmig sondern kreuzförmig ausgebildet ist und vier langlochförmige Bohrungen 8 aufweist. Die Ausbildung der Tragarme 6 und der Abstützfüße 7 ist gegenüber der Fig. 2 unverändert. Auch die vielfältige Positionierbarkeit der einzelnen Abstützfüße 6 ist durch die in diesem Fall vier Tragarme 6 mit vier Abstützfüßen 7 - wie gemäß der Erfindung vorgesehen - möglich. In dieser Fig. 3 ist auch die von der Drehachse D wegweisende Richtung R eingezeichnet, wobei nur in einer einzigen, von jeder Drehachse D radial wegführenden Richtung R jeweils ein Abstützfuß 7 an jedem Tragarm 6 angeordnet ist. Bezüglich der im Anspruch 1 geforderten Unabhängigkeit der Abstützfüße 7 voneinander sei erwähnt, dass diese nur so weit gilt, so weit die einzelnen Abstützpunkte 22 nicht zu nahe beieinander liegen. Falls diese zu nahe beieinander liegen, könnte eine Bewegungseinschränkung der Tragarme 6 durch Anstoßen aneinander gegeben sein. Da durch nahe beieinander liegende Abstützfüße 6 bzw. Abstützpunkte 22 ohnehin eine geringere Stabilität der Abstützauflage 1 gegeben wäre, stellt dies kein Problem für die Verwendung der vorliegenden Erfindung dar. Vielmehr ist durch die unabhängige Bewegung der einzelnen Abstützfüße 6 ein möglichst großes Areal unterhalb des Basiselements 5 für die Festlegung bzw. Abstützung der Abstützauflage 1 gegeben. Vor allem ist es dadurch ermöglicht, dass in einem Umkreis um die Drehachse D jeder einzelne Abstützfuß 6 am Motorgehäuse 3 abstützend angebracht werden kann. Allgemein sei angeführt, dass das Basiselement 5 im Wesentlichen flächig ausgebildet ist, wobei die Ausdehnung dieser Fläche normal zur Längserstreckung der Abstützfüße 7 steht. Die Längserstreckung der Tragarme 6 ist dagegen im Wesentlichen parallel zur Erstreckung der Fläche des Basiselementes 5.The Abstützauflage 1 in the assembled state is in Fig. 3 can be seen, according to this embodiment, the base member 5 is not circular but cross-shaped and has four slot-shaped holes 8. The formation of the support arms 6 and the Abstützfüße 7 is opposite to Fig. 2 unchanged. The multiple positioning of the individual support feet 6 is by four in this case support arms 6 with four support feet 7 - as in the Invention provided - possible. In this Fig. 3 is also the pointing away from the axis of rotation D direction R drawn, wherein only in a single, radially away from each axis of rotation D direction R each a support foot 7 is arranged on each support arm 6. With regard to the required in claim 1 independence of Abstützfüße 7 from each other it should be noted that this applies only so far, as far as the individual support points 22 are not too close to each other. If these are too close to each other, a restriction of movement of the support arms 6 could be given by abutment against each other. Since a lower stability of the Abstützauflage 1 would be given anyway by nearby support feet 6 and support points 22, this poses no problem for the use of the present invention. Rather, by the independent movement of the individual support feet 6 the largest possible area below the base element 5 given for the determination or support of the Abstützauflage 1. Above all, it is thereby made possible that in a circumference about the rotation axis D, each individual support foot 6 can be attached to the motor housing 3 in a supporting manner. It should generally be stated that the base element 5 has a substantially planar design, the extent of this surface being normal to the longitudinal extension of the support feet 7. The longitudinal extension of the support arms 6, however, is substantially parallel to the extension of the surface of the base member fifth

In Fig. 4 ist eine Frontansicht eines Motorgehäuses 3 samt aufgebrachter Demontagevorrichtung 12 abgebildet. Dabei liegt der Ausziehhebel 19 über die Positioniervorrichtung 15 und das Ringelement 17 am Basiselement 5 auf. Im unteren Bereich des Motorgehäuses 3 ist die in die Brennkammer vorstehende Spitze 33 der Injektordüse 4 ersichtlich.In Fig. 4 is a front view of a motor housing 3 together with applied dismantling device 12 shown. In this case, the pull-out lever 19 rests on the positioning element 15 and the ring element 17 on the base element 5. In the lower part of the motor housing 3, the projecting into the combustion chamber tip 33 of the injector nozzle 4 can be seen.

In Fig. 5 sind in einer Schnittdarstellung einerseits die Injektordüse 4 im Motorgehäuse 3 und andererseits die einzelnen Komponenten 27, 28, 29, 30 und 31 des Abstützfußes 7 dargestellt. Dabei sind die Längen der beiden dargestellten Abstützfüße 7 unterschiedlich. Die Länge kann dabei vor allem durch Bewegen der Komponente 29 gegenüber der Komponente 27 verändert werden. Sobald die gewünschte Länge eingestellt ist, wird durch Eindrehen der Komponente 30 in den Tragarm 6 über das Gewinde 34 eine Festklemmung der Komponenten 29 und 27 zueinander erreicht. Die Abstützfüße 7 sind über die Komponente 30 in Achsbohrungen (Durchtrittsöffnung 32) mit dem Gewinde 34 am Tragarm 6 anbringbar und festlegbar. In dieser Fig. 5 ist auch im Schnitt ersichtlich, dass die unterste Komponente 31 des Abstützfußes 7 an den unterschiedlich hohen Abstützpunkten 22 des Motorgehäuses 3 aufliegt. Die Ausziehstange 20 ist direkt mit dem aus dem Motorgehäuse 3 vorstehenden Kopf der Injektordüse 4 verbunden.In Fig. 5 are shown in a sectional view, on the one hand, the injector nozzle 4 in the motor housing 3 and on the other hand, the individual components 27, 28, 29, 30 and 31 of the outrigger 7. The lengths of the two illustrated Abstützfüße 7 are different. The length can be changed in particular by moving the component 29 relative to the component 27. Once the desired length is set, a clamping of the components 29 and 27 is achieved by screwing the component 30 into the support arm 6 via the thread 34 to each other. The support feet 7 are about the component 30 in Achsbohrungen (passage opening 32) with the thread 34 on the support arm 6 attachable and fixable. In this Fig. 5 is also apparent in section that the lowermost component 31 of the outrigger 7 rests on the different high support points 22 of the motor housing 3. The pull-out rod 20 is directly connected to the head of the injector nozzle 4 protruding from the motor housing 3.

In Fig. 6 ist ein weiterer Aspekt dargestellt, wonach das Basiselement 5 nicht normal zur Ausziehrichtung der Injektordüse 4 am Motorgehäuse 3 festgelegt werden muss. Vielmehr ist durch die über die konvex-kugelförmigen Oberflächenbereiche 16 und konkav-kugelförmigen Oberflächenbereiche 18 der Positioniervorrichtung 15 und des Ringelements 17 ein Ansetzen der Ausziehvorrichtung 12 auch an im Motorgehäuse 3 schräg gestellten Injektordüsen 4 möglich. Bevorzugt kann diesbezüglich vorgesehen sein, dass der konkav-kugelförmige Oberflächenbereich 18 des Ringelements 17 und der konvex-kugelförmige Oberflächenbereich 16 der Positionsvorrichtung 15 denselben Radius aufweisen. Die Durchtrittsöffnung 14 in der Positioniervorrichtung 15 kann so gewählt werden, dass deren Durchmesser nur geringfügig größer ist als der Durchmesser der Ausziehstange 20. Durch die beim Betätigen der Ausziehvorrichtung 2 auftretende Krafteinwirkung vom Ausziehhebel 19 über die Positioniervorrichtung 15 auf das Ringelement 17 wird dieses am Basiselement 5 angepresst und verrutscht durch die erhöhte Reibung nicht mehr am Basiselement 5. Grundsätzlich ist es aber möglich, dass seitliche Begrenzungsvorrichtungen gegen ein Verrutschen des Ringelements 17 am Basiselement 5 angebracht sind. Es wäre auch möglich, dass an der unteren planen Fläche des Ringelements 17 eine gleithemmende Schicht aufgebracht ist.In Fig. 6 is another aspect shown, according to which the base member 5 does not have to be set normal to the withdrawal direction of the injector 4 on the motor housing 3. On the contrary, by means of the convex-spherical surface areas 16 and concave-spherical surface areas 18 of the positioning device 15 and the ring element 17, it is possible to apply the pull-out device 12 also to injector nozzles 4 which are inclined in the motor housing 3. It may be preferred in this regard that the concave-spherical surface area 18 of the ring element 17 and the convex-spherical surface area 16 of the position device 15 have the same radius. The passage opening 14 in the positioning device 15 can be chosen so that its diameter is only slightly larger than the diameter of the pull-out 20. By the force occurring during actuation of the puller 2 force from Ausziehhebel 19 via the positioning device 15 on the ring member 17 this is the base element 5 pressed and slipped by the increased friction no longer on the base member 5. In principle, however, it is possible that lateral limiting devices against slipping of the ring member 17 are mounted on the base member 5. It would also be possible for a slide-inhibiting layer to be applied to the lower planar surface of the ring element 17.

Durch die vorliegende Erfindung ist somit eine Abstützauflage 1 für eine Demontagevorrichtung 12 gezeigt, bei der zumindest drei Abstützfüße 7 unabhängig voneinander auf unterschiedlichen Abstützpunkten 22 am Motorgehäuse 3 aufgesetzt werden können, wodurch eine größere Unabhängigkeit von der Ausbildung der Oberfläche des Motorgehäuses 3 gegeben ist. Zusätzlich wird diese Unabhängigkeit dadurch erhöht, dass die Abstützfüße 7 längenverstellbar sind und dass die Ausziehvorrichtung 2 über die Positioniervorrichtung 15 mit konvex-kugelförmigem Oberflächenbereich 16 unabhängig von der Ausrichtung des Basiselements 5 das Ausziehen bzw. Demontieren von schief gestellten Injektordüsen 4 aus dem Motorgehäuse 3 ermöglicht. Durch die längenverstellbaren Abstützfüße 7 ist kein Spiel mehr beim Aufsetzen der Abstützauflage 1 auf dem Motorgehäuse 3 gegeben. Das schräge Ansetzen der Ausziehvorrichtung 2 erhöht die Einsetzbarkeit. Generell ist durch die Erfindung eine universelle Abstützung der Abstützauflage 1 am Motorgehäuse 3 gegeben.By the present invention, a Abstützauflage 1 for a disassembly device 12 is thus shown, in which at least three Abstützfüße 7 can be placed independently on different support points 22 on the motor housing 3, whereby a greater independence from the formation of the surface of the motor housing 3 is given. In addition, this independence is increased by the fact that the support feet 7 are adjustable in length and that the extractor 2 on the positioning device 15 with convex-spherical surface portion 16 regardless of the orientation of the base member 5 allows the removal or disassembly of obliquely placed injector nozzles 4 from the motor housing 3 , Due to the length-adjustable support feet 7 game is no longer given when placing the Abstützauflage 1 on the motor housing 3. The oblique attachment of the puller 2 increases the usability. Generally, the invention provides a universal support of the Abstützauflage 1 on the motor housing 3.
