Fuel injection systems of internal combustion engines. The internal combustion engine can be operated here with suitable fuels, such as gasoline, natural gas or diesel.

Because in operation, the
Kraftstoffzuteiler unter anderem Temperaturbelastungen ausgesetzt, welche durch Aufheiz- und Abkühlvorgänge der Brennkraftmaschine entstehen. Die Ursache hierfür liegt daran, dass Kraftstoffzuteiler und Zylinderkopf in der Regel aus unterschiedlichen Werkstoffen bestehen und demzufolge unterschiedliche Wärmeausdehnungskoeffizienten besitzen. Daraus resultieren im Betrieb, insbesondere bei Temperaturdehnung, abhängig von der konkreten Ausgestaltung des Kraftstoffzuteilers und des Zylinderkopfes hohe lokale Spannungen im Bereich der Befestigungshalter. Die Befestigungshalter sind in der Regel durch großflächige Lotflächen mit dem Gehäuse verbunden. Hierbei ist eine vollständige und fehlerfreie Verlötung erforderlich, damit die Verbindung über die Lebensdauer gewährleistet ist. Dies bedeutet einen entsprechenden Aufwand zur Herstellung und gegebenenfalls Prüfung, um die Ausfallraten gering zu halten. Among other things, fuel injectors are exposed to temperature stresses which arise due to heating and cooling processes of the internal combustion engine. The reason for this is because fuel injectors and cylinder head usually consist of different materials and therefore have different thermal expansion coefficients. This results in operation, in particular temperature expansion, depending on the specific configuration of the fuel meter and the cylinder head high local stresses in the field of mounting bracket. The mounting brackets are usually connected by large area solder surfaces with the housing. This requires a complete and error-free soldering, so that the connection is guaranteed over the lifetime.

Offenbarung der Erfindung Der erfindungsgemäße Halter mit den Merkmalen des Anspruchs 1 und die erfindungsgemäße Anordnung mit den Merkmalen des Anspruchs 9 haben den Vorteil, dass eine verbesserte Ausgestaltung ermöglicht ist.

In particular, mechanical
Spannungen, die insbesondere aufgrund von Temperaturänderungen (Aufheizen oder Abkühlen) der Brennkraftmaschine auftreten, reduziert werden. Voltages which occur in particular due to temperature changes (heating or cooling) of the internal combustion engine can be reduced.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte The measures listed in the dependent claims are advantageous
Weiterbildungen des im Anspruch 1 angegebenen Halters und der im Anspruch 9 angegebenen Anordnung möglich. Further developments of the holder specified in claim 1 and the arrangement specified in claim 9 possible.
Vorteilhaft ist es, dass die geschlitzte Hülse über mehrere punktuelle Verbindungsstellen mit dem Grundkörper verbunden ist. Speziell kann die geschlitzte Hülse über mehrere Schweißpunkte, insbesondere auch nur zwei Schweißpunkte, mit dem Grundkörper verbunden sein. Somit ist keine flächige Verbindung, sondern eine punktuelle Verbindung vorgesehen. Dies ermöglicht kleine Relativbewegungen zwischen geschlitzter Hülse und Grundkörper. Im Unterschied zu einer linienförmigen Schweißnaht kann hierdurch die Beanspruchung der Verbindung zwischen der geschlitzten Hülse und dem Grundkörper verringert werden. It is advantageous that the slotted sleeve is connected via a plurality of selective connection points with the base body. Specifically, the slotted sleeve can be connected to the base body via a plurality of spot welds, in particular also only two spot welds. Thus, no area connection, but a point connection is provided. This allows small relative movements between slotted sleeve and body. In contrast to a line-shaped weld, this can reduce the stress on the connection between the slotted sleeve and the base body.
Vorteilhaft ist es auch, dass der Grundkörper zumindest ein Haltestück aufweist und dass die geschlitzte Hülse mit dem Haltestück des Grundkörpers verbunden ist. Hierbei ist es ferner vorteilhaft, dass der Grundkörper ein weiteres Haltestück und eine Hülse aufweist, dass das Haltestück über die Hülse mit dem weiteren Haltestück verbunden ist und dass sich entlang einer Befestigungsachse eine Durchgangsöffnung durch das weitere It is also advantageous that the base body has at least one retaining piece and that the slotted sleeve is connected to the retaining piece of the base body. In this case, it is further advantageous that the base body has a further holding piece and a sleeve, that the holding piece is connected via the sleeve with the further holding piece and that along a fastening axis a passage opening through the other
Haltestück, die Hülse, das Haltestück und die geschlitzte Hülse erstreckt. Hierdurch ist eine gebaute Ausgestaltung des Grundkörpers aus mehreren Einzelteilen möglich. Der  Holding piece, the sleeve, the holding piece and the slotted sleeve extends. As a result, a built embodiment of the body of several items is possible. Of the
Grundkörper kann hierbei aus dem weiteren Haltestück, der Hülse, dem Haltestück und gegebenenfalls weiteren Einzelteilen zusammengesetzt sein, wobei insbesondere The base body can in this case be composed of the further holding piece, the sleeve, the holding piece and optionally further individual parts, wherein in particular
Stanzbiegeteile und Drehteile zum Einsatz kommen können. Solch eine Ausgestaltung desStamped bent parts and turned parts can be used. Such an embodiment of
Grundkörpers ist kostengünstiger möglich als eine gegossene Ausgestaltung. Allerdings kann bei einer abgewandelten Ausgestaltung auch ein gegossener Grundkörper zum Einsatz kommen. Bei einem gegossenen Grundkörper können gegebenenfalls komplexe Ausgestaltungen realisiert werden, die an spezielle Bauraumverhältnisse besser anpassbar sein können. Die Verbindung des Grundkörpers mit der Komponente kann auf Basic body is cheaper possible than a cast design. However, in a modified embodiment, a cast base body can also be used. In the case of a cast base body, it is possible if desired to realize complex configurations which can be better adapted to specific space conditions. The connection of the main body with the component can on
unterschiedliche Weise erfolgen. Falls diesbezüglich eine großflächige Lotfläche zur Verbindung vorgesehen ist, dann wird diese aufgrund der ermöglichten Mikrobewegungen der geschlitzten Hülse weniger stark belastet. Somit kann der Grundkörper je nach Anwendungsfall beispielsweise aus einer massiven Grundkonstruktion oder in kostengünstiger weise aus Einzelteilen aufgebaut sein. Vorteilhaft ist es, dass ein Befestigungsmittel entlang der Befestigungsachse durch die Durchgangsöffnung führbar ist, um den Grundkörper mittelbar mit der Brennkraftmaschine zu verbinden und dass die geschlitzte Hülse eine unterbrochene ringförmige Anlagefläche aufweist, mit der die Hülse an einer Oberseite der Brennkraftmaschine anliegt, wenn der Grundkörper mittelbar mit der Brennkraftmaschine verbunden ist. Der Grundkörper wird hierbei mittels des Befestigungsmittels und der geschlitzten Hülse mit der done in different ways. If in this regard a large-area solder surface is provided for connection, then this is less heavily loaded due to the micro-movements of the slotted sleeve enabled. Thus, depending on the application, the basic body can be constructed, for example, from a solid basic construction or in a cost-effective manner from individual parts. It is advantageous that a fastening means along the attachment axis through the through hole is feasible to connect the body indirectly to the internal combustion engine and that the slotted sleeve has an interrupted annular contact surface with which the sleeve rests against an upper side of the internal combustion engine when the body is indirectly connected to the internal combustion engine. The main body is in this case by means of the fastening means and the slotted sleeve with the
Brennkraftmaschine, insbesondere einem Zylinderkopf der Brennkraftmaschine, verbunden. Bei der Oberseite der Brennkraftmaschine, an der die Hülse mit ihrer Anlagefläche anliegt, kann es sich somit insbesondere um die Oberseite des Zylinderkopfes der  Internal combustion engine, in particular a cylinder head of the internal combustion engine, connected. In the top of the internal combustion engine, on which the sleeve rests with its contact surface, it can thus in particular to the top of the cylinder head of the
Brennkraftmaschine handeln. Die Unterbrechung in der ringförmigen Anlagefläche der geschlitzten Hülse ist durch die geschlitzte Ausgestaltung der Hülse bedingt. Im Betrieb ergibt sich der Vorteil, dass bei Temperaturänderungen, bei denen sich der Zylinderkopf beispielsweise stärker ausdehnt als die Komponente, insbesondere der Kraftstoffverteiler (Kraftstoffzuteiler), oder als ein rohrförmiger Körper der Komponente, insbesondere des Kraftstoffverteilers, Zwangskräfte an der Kontaktfläche zwischen der unterbrochenen ringförmigen Anlagefläche der geschlitzten Hülse und der Oberseite der Internal combustion engine act. The interruption in the annular contact surface of the slotted sleeve is due to the slotted configuration of the sleeve. During operation, there is the advantage that in the case of temperature changes in which the cylinder head expands more than the component, in particular the fuel distributor (fuel distributor), or as a tubular body of the component, in particular the fuel distributor, constraining forces at the contact surface between the interrupted annular Contact surface of the slotted sleeve and the top of the
Brennkraftmaschine auftreten, wobei die geschlitzte Hülse einen Teil der Zwangskräfte aufnimmt. Hierbei ermöglichen Reibungskräfte zwischen der unterbrochenen, ringförmigen Anlagenfläche der geschlitzten Hülse und der Oberseite der Brennkraftmaschine einen gewissen Kraftschluss zwischen der geschlitzten Hülse und der Brennkraftmaschine. Im Ergebnis werden mechanische Spannungen an potenziell kritischen Stellen reduziert.  Internal combustion engine occur, wherein the slotted sleeve receives a portion of the constraining forces. In this case, frictional forces between the interrupted, annular bearing surface of the slotted sleeve and the upper side of the internal combustion engine allow a certain frictional connection between the slotted sleeve and the internal combustion engine. As a result, mechanical stresses are reduced at potentially critical locations.
Hierbei ist es ferner vorteilhaft, dass der Schlitz der geschlitzten Hülse einer Längsachse des rohrförmigen Körpers der Komponente, insbesondere eines Kraftstoffverteilers, zugewandt oder von dieser Längsachse abgewandt ist. Denn dann kann ein Teil der Zwangskräfte in besonders großem Umfang von der geschlitzten Hülse aufgenommen werden. In this case, it is further advantageous that the slot of the slotted sleeve faces a longitudinal axis of the tubular body of the component, in particular of a fuel distributor, or faces away from this longitudinal axis. Because then a part of the constraining forces can be absorbed in a particularly large extent by the slotted sleeve.
Der Schlitz der geschlitzten Hülse erstreckt sich in vorteilhafter Weise parallel zu der Befestigungsachse der geschlitzten Hülse von der Anlagefläche der geschlitzten Hülse zu einer von der Anlagefläche abgewandten Verbindungsfläche der geschlitzten Hülse. An der Verbindungsfläche der geschlitzten Hülse sind dann vorzugsweise die punktuellen The slot of the slotted sleeve extends in an advantageous manner parallel to the attachment axis of the slotted sleeve from the contact surface of the slotted sleeve to a side facing away from the contact surface connecting surface of the slotted sleeve. At the connecting surface of the slotted sleeve are then preferably the punctual
Verbindungsstellen mit dem Grundkörper vorgesehen. Somit kann der Grundkörper des Halters auch vergleichsweise steif ausgeführt werden, wie es bei einem gegossenen Grundkörper oder einem gebauten Grundkörper in der Regel der Fall ist, da ein Versatz entlang der Längsachse über die geschlitzte Hülse ermöglicht wird. Vorzugsweise ist der Grundkörper hierbei als gebauter Grundkörper ausgestaltet. Provided connection points with the body. Thus, the main body of the holder can also be made relatively stiff, as is usually the case with a cast base body or a built base body, since an offset along the longitudinal axis over the slotted sleeve is made possible. Preferably, the base body is designed here as a built base body.
Die Orientierung des Schlitzes in der geschlitzten Hülse wird hierbei passend zu der Wärmeausdehnung gewählt. Ferner wird die geschlitzte Hülse vorzugsweise nicht vollflächig, sondern punktuell mit dem Grundkörper verbunden. Hierbei kommen speziell Schweißpunkte zur Verbindung zum Einsatz. Durch diese beiden Maßnahmen, nämlich die geschlitzte Ausgestaltung der Hülse und die Anbindung mit vorzugsweise wenigen The orientation of the slot in the slotted sleeve is chosen to match the thermal expansion. Furthermore, the slotted sleeve is preferably not the entire surface, but selectively connected to the body. In this case, special welding points are used for connection. By these two measures, namely the slotted configuration of the sleeve and the connection with preferably a few
Schweißpunkten, wird ermöglicht, dass durch die Temperaturbelastungen Welding points, that is made possible by the temperature loads
Mikrobewegungen zugelassen werden. Diese Mikrobewegungen tragen dazu bei, den Spannungsanstieg zu reduzieren. Speziell durch eine Ausgestaltung als gebauter Halter mit geschlitzter Hülse können mehrere Vorteile erzielt werden. Die Beanspruchung an den Lotstellen, insbesondere zwischen dem Halter und der Komponente, insbesondere dem Kraftstoffzuteiler, wird reduziert. Da die geschlitzte Hülse nicht mit dem Rest der Anordnung, insbesondere nicht mit dem Grundkörper verlötet wird, ist die Betriebsbeanspruchung in diesem Bereich geringer als es bei einer (flächig) verlöteten Hülse der Fall wäre. Wenn im Gegensatz dazu die geschlitzte Hülse mit dem Grundkörper flächig verlötet wäre, dann würden an dieser zusätzlichen Lotstelle erhöhte Beanspruchungen im Betrieb auftreten, da dann an dieser Stelle kein Klaffen mehr zwischen Hülse und Grundkörper möglich wäre. Außerdem können die Eigenfrequenzen der Anordnung, insbesondere einer Brennstoffeinspritzanlage beziehungsweise einem Kraftstoffzuteiler, durch die Ausgestaltung der Hülse in höhereMicro movements are allowed. These micro-movements help to reduce the voltage increase. Especially by a configuration as a built holder with slotted sleeve several advantages can be achieved. The stress at the soldering points, in particular between the holder and the component, in particular the fuel feeder, is reduced. Since the slotted sleeve is not soldered to the rest of the arrangement, in particular not to the base body, the operating load in this area is lower than would be the case with a (flat) soldered sleeve. If, in contrast, the slotted sleeve would be soldered flat to the body, then increased stresses would occur in operation at this additional soldering point, since then at this point no more gaping between sleeve and body would be possible. In addition, the natural frequencies of the arrangement, in particular a fuel injection system or a fuel meter, by the design of the sleeve in higher
Bereiche verschoben werden. Areas are moved.

Im montierten Zustand erstreckt sich das Brennstoffeinspritzventil 9 in eine Bohrung 10 der Brennkraftmaschine 4, insbesondere einen Zylinderkopf 4 der Brennkraftmaschine 4. In solch einem Zylinderkopf 4 kann außerdem eine Befestigungsbohrung 1 1 , insbesondere eine Gewindebohrung 1 1 , ausgestaltet sein. In the assembled state, the fuel injection valve 9 extends into a bore 10 of the internal combustion engine 4, in particular a cylinder head 4 of the internal combustion engine 4. In such a cylinder head 4 can also be a mounting hole 1 1, in particular a threaded bore 1 1, be configured.
Die Anordnung 1 weist außerdem ein Befestigungsmittel 12 auf, das in diesem The arrangement 1 also has a fastening means 12 which is in this
Ausführungsbeispiel als Befestigungsschraube 12 ausgestaltet ist. Bei der Montage wird die Befestigungsschraube 12 entlang einer Befestigungsachse durch eine Durchgangöffnung 14 des Halters 3 geführt und in die Gewindebohrung 11 eingeschraubt. Über den Halter 3 ist dann die Komponente 2 an der Brennkraftmaschine 4 befestigt. Hierbei wird zugleich das Brennstoffeinspritzventil 9 über die Tasse 7 in der Bohrung 10 der Brennkraftmaschine 4 fixiert. Embodiment designed as a fastening screw 12. During assembly, the fastening screw 12 is guided along a fastening axis through a passage opening 14 of the holder 3 and screwed into the threaded bore 11. About the holder 3, the component 2 is then attached to the internal combustion engine 4. At the same time, the fuel injection valve 9 is fixed via the cup 7 in the bore 10 of the internal combustion engine 4.
Der Halter 3 weist einen Grundkörper 20 auf, der in diesem Ausführungsbeispiel mehrteilig ausgestaltet ist. Der Grundkörper 20 umfasst ein Haltestück 21 und ein weiteres HaltestückThe holder 3 has a main body 20, which is designed in several parts in this embodiment. The main body 20 includes a holding piece 21 and another holding piece
22. Die Haltestücke 21 , 22 können hierbei als Haltebleche 21 , 22 ausgestaltet sein. Ferner weist der Grundkörper 20 eine Hülse 23 auf, die zwischen den Haltestücken 21 , 22 angeordnet ist. Die einzelnen Teile des Grundkörpers 20, insbesondere die Haltestücke 21 , 22 und die Hülse 23, sind auf geeignete Weise, insbesondere durch flächige 22. The holding pieces 21, 22 can in this case be configured as holding plates 21, 22. Furthermore, the base body 20 has a sleeve 23 which is arranged between the holding pieces 21, 22. The individual parts of the base body 20, in particular the holding pieces 21, 22 and the sleeve 23, are suitably, in particular by flat
Lötverbindungen, miteinander verbunden. Solder joints, connected together.
Der Halter 3 weist außerdem eine geschlitzte Hülse 24 auf, die mit dem Grundkörper 20 verbunden ist. In diesem Ausführungsbeispiel ist die geschlitzte Hülse 24 mit dem Haltestück 21 verbunden. Die Verbindung der geschlitzten Hülse 24 mit dem Haltestück 21 erfolgt über wenige Schweißpunkte. Die geschlitzte Hülse 24 weist hierbei eine The holder 3 also has a slotted sleeve 24, which is connected to the main body 20. In this embodiment, the slotted sleeve 24 with the Holding piece 21 connected. The connection of the slotted sleeve 24 with the holding piece 21 via a few welds. The slotted sleeve 24 in this case has a
Anlagefläche 25 und eine von der Anlagefläche 25 abgewandte Verbindungsfläche 26 auf. Hierbei ist die geschlitzte Hülse 24 an ihrer Verbindungsfläche 26 über die Schweißpunkte mit dem Haltestück 21 verbunden. Somit ist die geschlitzte Hülse 24 an ihrer Contact surface 25 and facing away from the contact surface 25 connecting surface 26. Here, the slotted sleeve 24 is connected at its connection surface 26 via the weld points with the retaining piece 21. Thus, the slotted sleeve 24 is at its
Verbindungsfläche 26 nicht flächig, sondern ausschließlich punktuell mit dem Haltestück 21 verbunden. Da die geschlitzte Hülse 24 über mehrere punktuelle Verbindungsstellen mit dem Grundkörper 20 verbunden ist, werden teilweise Relativverschiebungen zwischen der geschlitzten Hülse 24 und dem Haltestück 21 ermöglicht, was insbesondere  Connecting surface 26 not flat, but only selectively connected to the retaining piece 21. Since the slotted sleeve 24 is connected via a plurality of selective connection points with the base body 20, partial relative displacements between the slotted sleeve 24 and the retaining piece 21 are partially possible, which is particularly
Mikrobewegungen zulässt. Micro movements allows.
Die Durchgangsöffnung 14 erstreckt sich in diesem Ausführungsbeispiel entlang der Befestigungsachse 13 nacheinander durch das weitere Haltestück 22, die Hülse 23, das Haltestück 21 und die geschlitzte Hülse 24. Im befestigten Zustand, in dem die The passage opening 14 extends in this embodiment along the mounting axis 13 successively through the further holding piece 22, the sleeve 23, the retaining piece 21 and the slotted sleeve 24. In the attached state in which the
Befestigungsschraube 12 in die Gewindebohrung 11 der Brennkraftmaschine 4 Fixing screw 12 in the threaded bore 11 of the internal combustion engine. 4
eingeschraubt ist, wird die geschlitzte Hülse 24 mit ihrer Anlagefläche 25 an eine Oberseite 27 der Brennkraftmaschine 4 gedrückt. Hierbei ist die Anlagefläche 25 der geschlitzten Hülse 24 so ausgestaltet, dass diese plan an der Oberfläche 27 der Brennkraftmaschine 4 anliegt. Die Anlagefläche 25 ist dadurch als unterbrochene ringförmige Anlagefläche 25 ausgestaltet, die aufgrund eines in der geschlitzten Hülse 24 vorgesehenen Schlitzes 28 unterbrochen ist. is screwed, the slotted sleeve 24 is pressed with its contact surface 25 to a top 27 of the internal combustion engine 4. Here, the contact surface 25 of the slotted sleeve 24 is designed so that it rests flat against the surface 27 of the internal combustion engine 4. The contact surface 25 is thereby configured as a broken annular contact surface 25, which is interrupted due to a provided in the slotted sleeve 24 slot 28.
Im Betrieb kommt es aufgrund von Temperaturänderungen, insbesondere bei einer Aufheizung der Brennkraftmaschine 4, insbesondere des Zylinderkopfes 4, auf die In operation, due to temperature changes, in particular during heating of the internal combustion engine 4, in particular of the cylinder head 4, the
Betriebstemperatur zu unterschiedlichen Ausdehnungen des rohrförmigen Körpers 5 und der Brennkraftmaschine 5. Der rohrförmige Körper 5 ist hierbei über zumindest einen weiteren Halter, der entsprechend dem Halter 3 ausgestaltet sein kann, mit der Operating temperature to different extents of the tubular body 5 and the internal combustion engine 5. The tubular body 5 is in this case via at least one other holder, which can be configured according to the holder 3, with the
Brennkraftmaschine 4 verbunden. Diese Differenz der Längenänderungen führt prinzipiell zu Zwängungen bzw. Kräften, die unter anderem zu an dem Halter 3 auftretenden mechanischen Beanspruchungen führen. Internal combustion engine 4 connected. This difference in the length changes leads in principle to constraints or forces that lead, inter alia, occurring on the holder 3 mechanical stresses.
Zwischen der Anlagefläche 25 der geschlitzten Hülse 24 und der Oberfläche 27 der Brennkraftmaschine 4 ist ein gewisser Reibschluss gebildet. Aufgrund der entstehenden Zwangskräfte kann es aufgrund der geschlitzten Ausgestaltung der geschlitzten Hülse 24 zu Mikrobewegungen kommen, wobei geringe Relativverschiebungen an der geschlitzten Hülse 24 möglich sind. Hierdurch kann ein Teil der Zwangskräfte aufgenommen werden. Die geschlitzte Hülse 24 übernimmt somit die Aufgabe, die unterschiedlichen Verschiebungen von der Komponente 2 und dem Zylinderkopf 4 zu einem gewissen Teil auszugleichen. Damit werden die Zwangsverschiebungen am Kraftstoffzuteiler reduziert, da ein Teil der Verschiebungen bereits von der geschlitzten Hülse 24 aufgenommen wird. Somit treten an der restlichen Struktur der Anordnung 1 , insbesondere an der Komponente 2 und dem Halter 3, geringere Verschiebungen auf. Speziell werden hierdurch auch die Beanspruchungen an den Lotverbindungen innerhalb des Halters 3 und zwischen dem Halter 3 und der Komponente 2, reduziert. Dies gilt entsprechend auch für anders ausgestaltete Verbindungen. Somit verringert sich die Betriebsbeanspruchung an der Anordnung 1. Between the contact surface 25 of the slotted sleeve 24 and the surface 27 of the internal combustion engine 4, a certain frictional engagement is formed. Due to the resulting constraining forces, micro-movements may occur due to the slotted configuration of the slotted sleeve 24, whereby slight relative displacements on the slotted sleeve 24 are possible. As a result, part of the coercive forces can be absorbed. The slotted sleeve 24 thus takes on the task to compensate for the different shifts of the component 2 and the cylinder head 4 to a certain extent. Thus, the forced displacements are reduced at the fuel meter, since a part of the displacements is already taken up by the slotted sleeve 24. Thus, smaller displacements occur at the remaining structure of the arrangement 1, in particular at the component 2 and the holder 3. Specifically, this also reduces the stresses on the solder joints within the holder 3 and between the holder 3 and the component 2. This also applies accordingly to differently configured connections. Thus, the operating stress on the assembly 1 decreases.
In diesem Ausführungsbeispiel ist der Schlitz 28 der geschlitzten Hülse 24 so an der geschlitzten Hülse 24 angeordnet, dass der Schlitz 28 von der Längsachse 6 abgewandt ist. Ferner erstreckt sich der Schlitz 28 parallel zu der Befestigungsachse 13. Durch diese gerichtete Montage beziehungsweise Anordnung der geschlitzten Hülse 24 kann eine besonders wirkungsvolle Reduzierung der Beanspruchung erreicht werden. Die In this embodiment, the slot 28 of the slotted sleeve 24 is arranged on the slotted sleeve 24, that the slot 28 is remote from the longitudinal axis 6. Further, the slot 28 extends parallel to the mounting axis 13. By this directed assembly or arrangement of the slotted sleeve 24, a particularly effective reduction of stress can be achieved. The
Reduzierung der Beanspruchung an potenziell kritischen Stellen ist dadurch besonders groß. Bei einer abgewandelten Ausgestaltung kann der Schlitz 28 auch der Längsachse 6 zugewandt sein, was ebenfalls eine vergleichsweise wirkungsvolle Reduzierung der Beanspruchung ermöglicht. Prinzipiell sind allerdings auch andere Anordnungen des Schlitzes 28 denkbar. Reducing the stress at potentially critical points is therefore particularly great. In a modified embodiment, the slot 28 may also be facing the longitudinal axis 6, which also allows a comparatively effective reduction of stress. In principle, however, other arrangements of the slot 28 are conceivable.
Somit können besonders aufgrund von Temperaturänderungen erzeugte Zwangskräfte beziehungsweise mechanische Spannungen im Bereich des Halters 3 wirkungsvoll zumindest zum Teil aufgenommen werden. Dieser vorteilhafte Effekt kann allerdings auch für Zwangskräfte beziehungsweise mechanische Spannungen ausgenutzt werden, die nicht oder nur zum Teil ihre Ursache in thermisch bedingten Längenänderungen haben. Thus, constraining forces or mechanical stresses generated in the region of the holder 3, in particular due to temperature changes, can be effectively at least partially absorbed. However, this advantageous effect can also be utilized for constraining forces or mechanical stresses that are not or only partially their cause in thermally induced changes in length.
Die Anordnung 1 weist vorzugsweise mehrere Halter auf, von denen zumindest ein Halter entsprechend dem Halter 3 ausgestaltet ist. Hierbei können allerdings auch mehrere derThe arrangement 1 preferably has a plurality of holders, of which at least one holder is designed in accordance with the holder 3. Here, however, several of
Halter oder alle Halter der Anordnung 1 entsprechend dem Halter 3 ausgestaltet sein. Holder or all holders of the arrangement 1 according to the holder 3 to be configured.
Die Erfindung ist nicht auf die beschriebenen Ausführungsbeispiele beschränkt. The invention is not limited to the described embodiments.
