Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Lagern eines ersten Bauteils, insbesondere einer Ölwanne, an einem zweiten Bauteil, insbesondere einem Motorblock einer Brennkraftmaschine.The present invention relates to a device for supporting a first component, in particular an oil pan, on a second component, in particular an engine block of an internal combustion engine.

Stand der TechnikState of the art

Derartige Einrichtung werden bei Kraftfahrzeugmotoren seit langem verwendet. Regelmäßig wird dabei die Ölwanne an dem Motorblock über Schrauben festgelegt, wobei zwischen dem Rand der Ölwanne und dem Motorblock eine Dichtung eingelegt ist. Eine derartige Befestigung der Ölwanne an dem Motorblock hat zur Folge, dass die bei dem Betrieb der Brennkraftmaschine auftretenden Schwingungen auf die Ölwanne übertragen werden. Dies führt nicht nur zu einer hohen Belastung der die Ölwanne mit dem Motorblock verbindenden Schrauben - eine entsprechend große Anzahl von entsprechend dimensionierten Schrauben ist erforderlich, um die Ölwanne zuverlässig mit dem Motorblock zu verbinden. Darüber hinaus führt die Übertragung der Vibrationen auf die Ölwanne zu einer Verschlechterung des akustischen Verhaltens der Brennkraftmaschine.Such devices have long been used in automotive engines. Regularly, the oil pan is fixed to the engine block via screws, with a seal is inserted between the edge of the oil pan and the engine block. Such attachment of the oil pan to the engine block has the consequence that the vibrations occurring during operation of the internal combustion engine are transmitted to the oil pan. This not only leads to a high load of the screws connecting the oil pan to the engine block - a correspondingly large number of appropriately sized screws is required to reliably connect the oil pan with the engine block. In addition, the transfer of the leads Vibrations on the oil pan to a deterioration of the acoustic behavior of the internal combustion engine.

Aus der Schrift DE-OS 37 12 052 ist eine Einrichtung zur Befestigung der Ölwanne an dem Block einer Brennkraftmaschine bekannt, die einen an einer Fußschiene umlaufend ausgebildeten, leistenförmigen Sims aufweist, an welchen die Ölwanne mit einer korrespondierend umlaufenden Anschlusskante dicht anschließbar ist. Eine Verringerung der Übertragung von Vibrationen von der Brennkraftmaschine auf die Ölwanne kann mit dieser Einrichtung, bei der die Ölwanne direkt an dem Motorblock anliegt, nicht erreicht werden.From DE-OS 37 12 052 a device for fixing the oil pan to the block of an internal combustion engine is known, which has a circumferentially formed on a foot rail, strip-shaped ledge on which the oil pan with a corresponding peripheral peripheral edge is tightly connected. A reduction in the transmission of vibrations from the engine to the oil pan can not be achieved with this device, in which the oil pan is applied directly to the engine block.

Weiterhin ist es bekannt, im Bereich der Anlage von Ölwanne und Motorblock Gummielemente vorzusehen, wobei Ölwanne und Gummielement über Schrauben mit dem Motorblock verspannt sind.Furthermore, it is known to provide rubber elements in the area of the system of oil sump and engine block, wherein oil sump and rubber element are braced by screws to the engine block.

Es hat sich jedoch gezeigt, dass auch hierdurch keine Verringerung der Übertragung von Vibrationen des Motors auf die Ölwanne in dem gewünschten Maß erreicht wird.However, it has been found that this also no reduction in the transmission of vibrations of the engine is achieved on the oil pan to the desired extent.

Ein Gegenstand gemäss Anspruch 1, erster Teil ist aus der FR-A-2 812 909 (Fig. 3) bekannt.An article according to claim 1, first part is known from FR-A-2 812 909 (Figure 3).

Darstellung der ErfindungPresentation of the invention

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Lagern eines ersten Bauteils, insbesondere einer Ölwanne, an einem zweiten Bauteil, insbesondere einem Motorblock einer Brennkraftmaschine anzugeben, bei der die Übertragung von Vibrationen des zweiten Bauteils auf das erste Bauteil vermindert wird.The present invention has for its object to provide a device for storing a first component, in particular an oil pan, on a second component, in particular an engine block of an internal combustion engine, in which the transmission of vibrations of the second component is reduced to the first component.

Diese Aufgabe wird gemäß der vorliegenden Erfindung bei einer gattungsgemäßen Einrichtung gelöst durch die Merkmale gemäss Anspruch 1.This object is achieved according to the present invention in a generic device by the features according to claim 1.

Durch die erfindungsgemäße Gestaltung kann eine erhebliche Reduktion der Übertragung von Vibrationen vom Motor auf die Ölwanne erreicht werden. Dies ermöglicht nicht nur die Anzahl der zweiten Verbindungsmittel zur reduzieren, sondern verbessert auch den akustischen Einfluss der Ölwanne. Darüber hinaus ist es mit der vorliegenden Erfindung möglich, eine akustische Entkopplung zu erzielen, welche bereits bei sehr tiefen Frequenzen, selbst bei Frequenzen kleiner als 180 Hz, einsetzt. Schließlich ermöglicht die vorliegende Erfindung nicht nur eine Lagerung des ersten Bauteils an dem zweiten Bauteil, sondern auch eine Abdichtung der beiden Bauteile gegeneinander.The inventive design, a significant reduction in the transmission of vibrations from the engine to the oil pan can be achieved. This not only enables the number of second connection means to be reduced, but also improves the acoustic impact of the sump. Moreover, it is possible with the present invention to achieve an acoustic decoupling, which already starts at very low frequencies, even at frequencies less than 180 Hz. Finally, the present invention not only allows a bearing of the first component on the second component, but also a seal of the two components against each other.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass erster und / oder zweiter Stützkörper im Wesentlichen steif ausgebildet sind und insbesondere aus Metall bestehen. Hierdurch kann insbesondere eine zuverlässige Festlegung und Abdichtung der erfindungsgemäßen Einrichtung an dem ersten Bauteil beziehungsweise dem zweiten Bauteil erreicht werden.According to an advantageous development of the invention it is provided that the first and / or second support body are substantially rigid and in particular consist of metal. In this way, in particular a reliable fixing and sealing of the device according to the invention on the first component or the second component can be achieved.

Weiterhin hat es sich als vorteilhaft erwiesen, wenn erster und / oder zweiter Stützkörper als umlaufender Körper ausgebildet sind.Furthermore, it has proven to be advantageous if the first and / or second support body are formed as a rotating body.

Vorteilhafterweise ist weiterhin vorgesehen, dass der insbesondere aus Elastomer bestehende elastische Körper fest mit erstem und zweitem Stützkörper verbunden ist. Auf diese Weise können die statischen Lagerbeziehungsweise Haltekräfte zwischen erstem und zweitem Stützkörper übertragen werden. Dabei wird aufgrund der elastischen Eigenschaften des elastischen Körpers einer Übertragung von Vibrationen zwischen den beiden Stützkörpern und somit zwischen erstem Bauteil / Ölwanne und zweitem Bauteil / Brennkraftmaschine entgegengewirkt.Advantageously, it is further provided that the existing in particular of elastomeric elastic body is firmly connected to the first and second support body. In this way, the static Lagerbeziehungsweise holding forces between the first and second support body be transmitted. Due to the elastic properties of the elastic body, a transmission of vibrations between the two support bodies and thus between the first component / oil sump and the second component / internal combustion engine is counteracted.

Eine gute Abdichtung wird dadurch erreicht, dass im Bereich der Anlagefläche von erstem Stützkörper zum ersten Bauteil eine oder mehrere Dichtlippen vorgesehen sind, die insbesondere einstückig mit dem elastischen Körper ausgebildet sind. Dabei hat es sich als vorteilhaft erwiesen, an dieser Stelle zwei Dichtlippen vorzusehen. Durch diese Gestaltung wird auch eine Trennung der Funktionen erreicht. Die Dichtlippe dichtet den ersten Stützkörper gegenüber dem ersten Bauteil ab und wird bei der Montage der erfindungsgemäßen Einrichtung zur Erzielung einer guten Abdichtung elastisch verformt. Der elastische Körper hingegen, welcher den ersten und zweiten Stützkörper verbindet, wird bei der Montag der erfindungsgemäßen Einrichtung nicht verformt und ermöglicht daher eine verbesserte Entkopplung beziehungsweise Schwingungsisolation zwischen erstem und zweitem Bauteil und dies unabhängig von irgendwelchen Schraubenkräften.A good seal is achieved in that one or more sealing lips are provided in the region of the contact surface of the first support body to the first component, which are in particular formed integrally with the elastic body. It has proven to be advantageous to provide two sealing lips at this point. This design also achieves a separation of the functions. The sealing lip seals the first support body relative to the first component and is elastically deformed during assembly of the device according to the invention to achieve a good seal. The elastic body, however, which connects the first and second support body is not deformed at the Monday of the device according to the invention and therefore allows improved decoupling or vibration isolation between the first and second component and this regardless of any screw forces.

Alternativ ist vorgesehen, dass im Bereich der Anlagefläche vom zweiten Stützkörper zum zweiten Bauteil eine oder mehrere Dichtlippen vorgesehen sind, die insbesondere einstückig mit dem elastischen Körper ausgebildet sind. Hier hat es sich als hinreichend gezeigt, eine einzige Dichtlippe vorzusehen, welche am inneren Rand des zweiten Stützkörpers ausgebildet ist. Durch die einstückige Gestaltung des elastischen Körpers mit den Dichtlippen wird die Herstellung vereinfacht.Alternatively, it is provided that one or more sealing lips are provided in the region of the contact surface of the second support body to the second component, which are in particular formed integrally with the elastic body. Here it has been found to be sufficient to provide a single sealing lip, which is formed on the inner edge of the second support body. The one-piece design of the elastic body with the sealing lips simplifies manufacture.

Bei einer besonders vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, dass der erste Stützkörper winklig ausgebildet ist und einen Verbindungsabschnitt, der sich im Wesentlichen senkrecht zur Dichtungsebene erstreckt, sowie einen Stützabschnitt aufweist, der sich im Wesentlichen parallel zur Dichtungsebene erstreckt. Mit Dichtungsebene ist dabei die Ebene der Anlagefläche zwischen zweitem Bauteil und zweitem Stützkörper gemeint. Durch diese Gestaltung des ersten Stützkörpers wird eine besonders hohe Stabilität der erfindungsgemäßen Einrichtung aber auch eine zuverlässige Isolation der Ölwanne gegenüber dem Motorblock erreicht.In a particularly advantageous embodiment of the invention, it is provided that the first support body is formed at an angle and a connecting portion, which is substantially perpendicular to the sealing plane extends, and has a support portion which extends substantially parallel to the sealing plane. With sealing plane is meant the plane of the contact surface between the second component and the second support body. By this design of the first support body, a particularly high stability of the device according to the invention but also a reliable insulation of the oil pan relative to the engine block is achieved.

Eine zuverlässige und kostengünstig herstellbare Verbindung zwischen erstem Stützkörper und erstem Bauteil kann dadurch erreicht werden, dass die ersten Verbindungsmittel als Laschen ausgebildet sind, welche in korrespondierende Ausnehmungen des ersten Bauteils, insbesondere der Ölwanne, einführbar sind.A reliable and inexpensive to produce connection between the first support body and the first component can be achieved in that the first connecting means are designed as tabs, which are in corresponding recesses of the first component, in particular the oil pan, insertable.

Gemäß einer Weiterbildung dieses Erfindungsgedankens ist vorgesehen, dass das erste Bauteil, insbesondere die Ölwanne, und der erste Stützkörper durch Umbiegen der Laschen miteinander fest verbindbar sind, wodurch eine formschlüssige Verbindung zwischen Ölwanne und erstem Stützkörper erreicht werden kann.According to one embodiment of this inventive concept, it is provided that the first component, in particular the oil pan, and the first support body are firmly connected to each other by bending the tabs, whereby a positive connection between the oil pan and the first support body can be achieved.

Vorteilhafterweise sind die Laschen an dem ersten Stützkörper, insbesondere dessen Verbindungsabschnitt, ausgebildet.Advantageously, the tabs on the first support body, in particular its connecting portion formed.

Die Montage wird dadurch erleichtert, dass die Laschen an der Biegestelle einen Abschnitt mit verringertem Querschnitt aufweisen. Dies ermöglicht es die zum Umbiegen der Laschen erforderlichen Biegekräfte zu reduzieren.The assembly is facilitated by the fact that the tabs at the bending point have a section with a reduced cross-section. This makes it possible to reduce the bending forces required for bending the tabs.

Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung sind Ausnehmungen vorgesehen, welche sich durch den zweiten Stützkörper und wenigstens einen Teil des elastischen Körpers erstrecken. Dies hat den Vorteil, dass die Steifigkeit des elastischen Körpers angepasst werden kann, um die Übertragung von Schwingungen des Motorblocks auf die Ölwanne zu verringern. Insbesondere kann durch die Anpassung der Steifigkeit des elastischen Körpers eine Schwingungsentkopplung in dem gewünschten Frequenzbereich erreicht werden. Ein weiterer Vorteil der Ausnehmungen ist, dass das Gewicht der erfindungsgemäßen Einrichtung reduziert wird.According to a particularly advantageous embodiment of the invention recesses are provided which extend through the second support body and at least a portion of the elastic body. This has the advantage that the stiffness of the elastic body can be adjusted to the Transmission of vibrations of the engine block to reduce the oil pan. In particular, by adjusting the stiffness of the elastic body, a vibration decoupling in the desired frequency range can be achieved. Another advantage of the recesses is that the weight of the device according to the invention is reduced.

Gemäß einer Weiterbildung dieses Erfindungsgedankens ist vorgesehen, dass die Ausnehmungen zum Motorblock hin offen und gegenüber dem von der Ölwanne umschlossenen Raum durch den elastischen Körper abgedichtet sind.According to a development of this inventive idea, it is provided that the recesses are sealed to the engine block and sealed off from the space enclosed by the oil sump by the elastic body.

Eine weitere Verbesserung wird dadurch erreicht, dass die Ausnehmungen derart ausgebildet sind, dass durch die Ausnehmungen ein Werkzeug einführbar ist, um den ersten Stützkörper abzustützen. Dies ist insbesondere bei der Montage von Vorteil, da beim Verbinden des ersten Stützkörpers mit der Ölwanne (erstes Bauteil) ein Verbiegen des ersten Stützkörpers vermieden werden kann. Dies gilt insbesondere bei der erfindungsgemäßen Gestaltung, bei der der erste Stützkörper Laschen aufweist, welche zum Verbinden von Ölwanne und erstem Stützkörper umgebogen werden.A further improvement is achieved in that the recesses are formed such that a tool is insertable through the recesses in order to support the first support body. This is particularly advantageous during assembly, since bending of the first support body can be avoided when connecting the first support body to the oil sump (first component). This is especially true in the design according to the invention, in which the first support body has tabs, which are bent for connecting the oil pan and the first support body.

Eine besonders gute Abstützung des ersten Stützkörpers bei der Montage kann dadurch erreicht werden, dass wenigstens einige der Ausnehmungen benachbart zu den ersten Verbindungsmitteln angeordnet sind.A particularly good support of the first support body during assembly can be achieved in that at least some of the recesses are arranged adjacent to the first connection means.

Weiterhin ist erfindungsgemäß vorgesehen, dass der zweite Stützkörper Verbindungsöffnungen aufweist, durch die die Verbindungsmittel zum Verbinden mit dem ersten Bauteil durchführbar sind. Als zweite Verbindungsmittel können insbesondere Schrauben vorgesehen werden, welche in den Motorblock eingeschraubt werden.Furthermore, the invention provides that the second support body has connection openings through which the connection means for connecting to the first component can be performed. In particular screws can be provided as a second connecting means, which are screwed into the engine block.

Die vorliegende Erfindung bezieht sich darüber hinaus auf eine vormontierte Ölwanneneinheit, welche eine Ölwanne aufweist, die mit einer Einrichtung gemäß der vorhergehend beschriebenen Art verbunden ist. Eine solche vormontierte Ölwanneneinheit erleichtert die Montage und verkürzt die Montagezeit bei der Fertigstellung des Automobils.The present invention further relates to a preassembled oil pan assembly having an oil pan connected to a device of the type previously described. Such a preassembled oil pan unit facilitates the assembly and shortens the assembly time in the completion of the automobile.

Gemäß einer Weiterbildung dieses Erfindungsgedankens ist vorgesehen, dass der erste Stützkörper ein Verbindungsflansch der Ölwanne ist.According to a development of this invention, it is provided that the first support body is a connecting flange of the oil pan.

Ausführung der ErfindungEmbodiment of the invention

In den Figuren ist eine Einrichtung 1 zum Lagern eines als eine Ölwanne ausgebildeten ersten Bauteils an einem als den Motorblock einer Brennkraftmaschine ausgebildeten zweiten Bauteil dargestellt. Dabei ist in den Figuren lediglich die Einrichtung 1, nicht jedoch das erste Bauteil (Ölwanne) und das zweite Bauteil (Motorblock) dargestellt.In the figures, a device 1 for storing a formed as an oil pan first component is shown on a formed as the engine block of an internal combustion engine second component. In this case, only the device 1, but not the first component (oil pan) and the second component (engine block) is shown in the figures.

Die Einrichtung 1 weist einen ersten Stützkörper 2 und zweiten Stützkörper 3 auf. Der erste Stützkörper 2 kann über weiter unten näher beschriebene erste Verbindungsmittel an dem ersten Bauteil festgelegt werden. Der zweite Stützkörper 3 kann über nicht dargestellte zweite Verbindungsmittel an dem zweiten Bauteil festgelegt werden.The device 1 has a first support body 2 and second support body 3. The first support body 2 can be fixed to the first component via first connection means described in greater detail below. The second support body 3 can be fixed to the second component via second connecting means (not shown).

Die erfindungsgemäße Einrichtung weist weiterhin einen elastischen Körper 4 auf, welcher den ersten und zweiten Stützkörper 2, 3 flüssigkeitsdicht verbindet und den ersten Stützkörper 2 elastisch bewegbar an dem zweiten Stützkörper 3 festlegt.The device according to the invention further comprises an elastic body 4 which connects the first and second support body 2, 3 in a liquid-tight manner and fixes the first support body 2 elastically movably on the second support body 3.

Der erste Stützkörper 2 und zweite Stützkörper 3 sind als steife Körper ausgebildet und bestehen aus Metall, vorzugsweise Stahl. Dabei sind erster und zweiter Stützkörper als umlaufende Körper ausgebildet entlang einem in sich geschlossenen Linienzug. Der aus Elastomer bestehende elastische Körper 4 ist, wie insbesondere aus den Fig. 3 bis 7 ersichtlich ist, fest mit erstem und zweitem Stützkörper 2, 3 verbunden. Lediglich in der Explosionsdarstellung von Fig. 2 sind erster Stützkörper 2, elastischer Körper 4 und zweiter Stützkörper 3 gesondert voneinander dargestellt, um den Aufbau der erfindungsgemäßen Einrichtung besser darstellen zu können. Die feste Verbindung der elastischen Körpers 4 mit dem ersten Stützkörper 2 und dem zweiten Stützkörper 3 wird dadurch erreicht, dass der elastische Körper 4 durch Anvulkanisieren mit dem ersten Stützkörper 2 und dem zweiten Stützkörper 3 dauerfest verbunden ist. Somit bilden beim fertigen Produkt erster Stützkörper 2, zweiter Stützkörper 3 und elastischer Körper 4 eine Einheit.The first support body 2 and second support body 3 are formed as rigid bodies and made of metal, preferably steel. In this case, the first and second support body are designed as rotating bodies along a closed continuous line. The elastomeric elastic Body 4 is, as is apparent in particular from FIGS. 3 to 7, firmly connected to the first and second support body 2, 3. Only in the exploded view of Fig. 2, the first support body 2, elastic body 4 and second support body 3 are shown separately from each other to better represent the structure of the device according to the invention can. The firm connection of the elastic body 4 with the first support body 2 and the second support body 3 is achieved in that the elastic body 4 is permanently connected by scorching with the first support body 2 and the second support body 3. Thus, in the finished product first support body 2, second support body 3 and elastic body 4 form a unit.

Anders als in den Figuren dargestellt, kann der erste Stützkörper auch als ein Verbindungsflansch der Ölwanne ausgebildet sein. Dieser kann insbesondere durch einen umgebogenen Rand der Ölwanne erzeugt werden. Bei dieser Ausgestaltung wird der elastische Körper 4 vorteilhafterweise durch Anvulkanisieren direkt mit dm Verbindungsflansch verbunden.Unlike shown in the figures, the first support body may also be formed as a connecting flange of the oil pan. This can be generated in particular by a bent edge of the oil pan. In this embodiment, the elastic body 4 is advantageously connected by vulcanization directly with dm connecting flange.

Wie insbesondere aus den Fig. 3 bis 7 ersichtlich ist, ist im Bereich der Anlagefläche 5 von erstem Stützkörper 2 zum ersten Bauteil ein oder mehrere Dichtlippen 6 vorgesehen. Bei den in den Figuren dargestellten Ausführungsformen sind dabei zwei Dichtlippen 6, 6' ausgebildet. Die Dichtlippen bestehen wie der elastische Körper 4 aus Elastomer und sind einstückig mit diesem ausgebildet.As can be seen in particular from FIGS. 3 to 7, one or more sealing lips 6 are provided in the region of the contact surface 5 of the first support body 2 with respect to the first component. In the embodiments shown in the figures, two sealing lips 6, 6 'are formed. The sealing lips, like the elastic body 4, are made of elastomer and are integrally formed therewith.

Im Bereich der Anlagefläche 7 von zweitem Stützkörper 3 zum zweiten Bauteil können gleichfalls ein oder mehrere Dichtlippen 8 vorgesehen werden, wobei die in der Zeichnung dargestellte Ausführungsform nur eine einzige Dichtlippe 8 aufweist. Dabei ist die Dichtlippe 8 an dem inneren Rand des zweiten Stützkörpers 3 angeordnet und steht elastisch verformbar über die Anlagefläche 7 vor. Auch die Dichtlippe 8 ist einstückig mit dem elastischen Körper 4 ausgebildet. Entsprechend können die Dichtlippe 8, der elastische Körper 4 und die Dichtlippen 6, 6' besonders kostengünstig in einem einzigen Arbeitsgang hergestellt werden.In the area of the contact surface 7 of the second support body 3 to the second component, one or more sealing lips 8 can also be provided, wherein the embodiment shown in the drawing has only a single sealing lip 8. In this case, the sealing lip 8 is arranged on the inner edge of the second support body 3 and is elastically deformable over the contact surface 7. Also, the sealing lip 8 is integral with the elastic Body 4 formed. Accordingly, the sealing lip 8, the elastic body 4 and the sealing lips 6, 6 'can be produced in a particularly cost-effective manner in a single operation.

Der erste Stützkörper 2 winklig ausgebildet und weist einen Verbindungsabschnitt 9, der sich im Wesentlichen senkrecht zur Dichtungsebene erstreckt, sowie einen Stützabschnitt 10 auf, welcher sich im Wesentlichen parallel zur Dichtungsebene erstreckt. Vorliegend schließen Verbindungsabschnitt 9 und Stützabschnitt 10 einen Winkel von etwa 90° ein. Dabei weist der Verbindungsabschnitt 9 zum ersten Bauteil hin.The first support body 2 is formed at an angle and has a connecting portion 9, which extends substantially perpendicular to the sealing plane, and a support portion 10, which extends substantially parallel to the sealing plane. In the present case, connecting section 9 and supporting section 10 form an angle of approximately 90 °. In this case, the connecting portion 9 to the first component.

Insbesondere in den Fig. 2 und 4 lässt sich erkennen, wie erfindungsgemäß die ersten Verbindungsmittel 11 näher ausgestaltet sind. Bei den Verbindungsmitteln 11 handelt es sich bei den in den Figuren dargestellten Ausführungsform um Laschen, welche in korrespondierende Ausnehmungen der Ölwanne eingeführt werden können. Dabei erfolgt eine Verbindung zwischen erstem Bauteil und erstem Stützkörper 2 durch Umbiegen der Laschen nach dem Einführen in die korrespondierende Ausnehmungen des ersten Bauteils. Dabei sind die Laschen 11 an dem Verbindungsabschnitt 9 des ersten Stützkörpers 2 ausgebildet. Bei den Laschen 11 handelt es sich um vorstehende Abschnitte des aus Metall gefertigten Verbindungsabschnitt 9. Um das Umbiegen der Laschen zu erleichtern, kann vorgesehen sein, dass die Laschen 11 an der Biegestelle 12 einen Abschnitt mit verringertem Querschnitt aufweisen. Dies ist in Fig. 4 jedoch nicht dargestellt.In particular, in FIGS. 2 and 4 can be seen how inventively the first connecting means 11 are designed closer. In the case of the connection means 11, the embodiments shown in the figures are tabs which can be inserted into corresponding recesses in the oil sump. In this case, a connection between the first component and the first support body 2 by bending the tabs after insertion into the corresponding recesses of the first component. The tabs 11 are formed on the connecting portion 9 of the first support body 2. In the tabs 11 are protruding portions of the metal made connecting portion 9. In order to facilitate the bending of the tabs, it can be provided that the tabs 11 have a portion of reduced cross-section at the bending point 12. This is not shown in Fig. 4.

Weiterhin sind erfindungsgemäß Ausnehmungen 13 vorgesehen, welche sich durch den zweiten Stützkörper 3 und wenigstens einen Teil des elastischen Körpers 4 erstrecken. Bei der in den Figuren dargestellten Ausführungsform sind die Ausnehmungen 13 zum Motorblock hin offen ausgebildet, jedoch gegenüber dem von der Ölwanne umschlossenen Raum durch den elastischen Körper 4 und die Dichtlippen 6, 6', 8 abgedichtet. Durch die Ausnehmungen in dem elastischen Körper 4 kann dessen Steifigkeit gezielt beeinflusst werden. Entsprechend kann die Elastizität zwischen erstem Stützkörper 2 und zweitem Stützkörper 3 durch die Ausnehmungen 13 auf das gewünschte Maß eingestellt werden, um insbesondere die Übertragung von Vibrationen zwischen Motorblock und Ölwanne zu verringern und um eine akustische Entkopplung in dem gewünschten Frequenzbereich zu erreichen.Furthermore, recesses 13 are provided according to the invention, which extend through the second support body 3 and at least part of the elastic body 4. In the embodiment shown in the figures, the recesses 13 are formed open towards the engine block, but with respect to the area enclosed by the oil pan space by the elastic Body 4 and the sealing lips 6, 6 ', 8 sealed. Through the recesses in the elastic body 4, its rigidity can be selectively influenced. Accordingly, the elasticity between the first support body 2 and the second support body 3 can be adjusted by the recesses 13 to the desired level, in particular to reduce the transmission of vibrations between the engine block and oil pan and to achieve an acoustic decoupling in the desired frequency range.

Die Ausnehmungen 13 sind darüber hinaus derart ausgebildet, dass durch die Ausnehmungen 13 ein Werkzeug einführbar ist, um den ersten Stützkörper 2 abzustützen. Hierzu sind einige der Ausnehmungen 13 jeweils benachbart zu den als Laschen ausgebildeten ersten Verbindungsmitteln 11 angeordnet. Beim Verbinden der erfindungsgemäßen Einrichtung 1 mit der Ölwanne (erstes Bauteil) werden die Verbindungsmittel 11 in die korrespondierenden Ausnehmungen der Ölwanne eingeführt. Beim Umbiegen der Laschen 11 wird durch die Ausnehmungen 13 ein Werkzeug eingeführt, welches sich an dem ersten Stützkörper 2, insbesondere dem Stützabschnitt 10 abstützt und die bei Umbiegen der Laschen 11 auftretenden Kräfte ganz oder teilweise aufnimmt, so dass insbesondere eine unzulässige Deformation des zweiten Stützkörpers 3 vermieden werden kann.The recesses 13 are also designed such that a tool is insertable through the recesses 13 in order to support the first support body 2. For this purpose, some of the recesses 13 are each arranged adjacent to the latches formed as first connecting means 11. When connecting the device 1 of the invention with the oil pan (first component), the connecting means 11 are inserted into the corresponding recesses of the oil pan. When bending the tabs 11, a tool is introduced through the recesses 13, which is supported on the first support body 2, in particular the support portion 10 and the forces occurring when bending the tabs 11 wholly or partially receives, so that in particular an impermissible deformation of the second support body 3 can be avoided.

Weiterhin sind in dem zweiten Stützkörper 3 Verbindungsöffnungen 14 vorgesehen, durch die die zweiten Verbindungsmittel zum Verbinden mit dem Motorblock (zweites Bauteil) durchführbar sind. Als Verbindungsmittel können insbesondere Schrauben verwendet werden, die durch die Verbindungsöffnungen 14 in den Motorblock eingeschraubt werden. Um dies zu erleichtern, springt der erste Stützkörper 2 in dem Bereich, in dem die Verbindungsöffnungen 14 angeordnet sind, zurück und ist um die Verbindungsöffnung 14 herum geführt. Bei der in Figuren dargestellten Ausführungsformen weist die Einrichtung 1 acht Verbindungsöffnungen 14 sowie siebenundfünfzig Ausnehmungen 13 auf, welche über den Umfang der Einrichtung 1 verteilt angeordnet sind.Furthermore, in the second support body 3 connecting openings 14 are provided, through which the second connecting means for connecting to the engine block (second component) can be carried out. In particular screws can be used as connecting means, which are screwed through the connection openings 14 in the engine block. To facilitate this, the first support body 2 jumps back in the region in which the connection openings 14 are arranged and is guided around the connection opening 14. In the embodiments shown in FIGS., The device 1 has eight connection openings 14 and fifty-seven recesses 13, which are arranged distributed over the circumference of the device 1.

Darüber hinaus weist der zweite Stützkörper 3 einen umgebogenen Rand 15 auf, welcher an der Außenseite des zweiten Stützkörpers 3 umlaufend angeordnet ist. Dabei weist der umgebogene Rand 15, welcher sich in etwa senkrecht zur Anlagefläche 7 erstreckt, weg vom zweiten Bauteil.In addition, the second support body 3 has a bent edge 15, which is arranged circumferentially on the outside of the second support body 3. In this case, the bent edge 15, which extends approximately perpendicular to the contact surface 7, away from the second component.

Die Ausnehmungen 13 sind auch bei der Herstellung der erfindungsgemäßen Einrichtung 1 von Bedeutung. Bei der Herstellung werden nämlich erster und zweiter Stützkörper in eine Form eingelegt, wobei Haltezapfen vorgesehen sind, welche sich durch die in dem zweiten Stützkörper 3 ausgebildeten Ausnehmungen 13 erstrecken. Durch diese Haltezapfen wird der erste Stützkörper 2 im gewünschten Abstand vom zweiten Stützkörper 3 gehalten. Darauf wird Elastomer in die Form eingebracht, um den elastischen Körper 4 und die Dichtlippen 6, 6' und 8 zu formen. Dort, wo die Haltezapfen angeordnet sind, bleiben beim Herausnehmen der erfindungsgemäßen Einrichtung 1 aus der Form die Ausnehmungen 13 zurück.The recesses 13 are also important in the production of the device 1 according to the invention. In the manufacture, first and second support bodies are in fact inserted into a mold, wherein holding pins are provided, which extend through the recesses 13 formed in the second support body 3. By means of these retaining pins, the first supporting body 2 is held at the desired distance from the second supporting body 3. Then, elastomer is introduced into the mold to form the elastic body 4 and the sealing lips 6, 6 'and 8. Where the retaining pins are arranged, the recesses 13 remain when removing the device 1 according to the invention from the mold.
