Description
Die Erfindung betrifft schwingungs- und körperschallisolierende Lager nach dem Oberbegriff des Patentanspruchs 1.The invention relates to vibration and structure-borne sound insulating bearing according to the preamble of
Bekannte Lager dieser Art bestehen üblicherweise aus blockartig geformten Elastomeren, vgl. z.B.
Solche Lager in ihrer schwingungs- und körperschallisolierenden Funktion sowie insbesondere bezüglich ihrer mechanischen Stabilität und Nichtbrennbarkeit zu verbessern, ist das Problem, das der vorliegenden Erfindung zugrundeliegt und bereits grundsätzlich durch ein gattungsgemäßes Lager mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst wird.To improve such bearings in their vibration and structure-borne sound insulating function and in particular with regard to their mechanical stability and non-combustibility, is the problem underlying the present invention and is already solved in principle by a generic bearing with the characterizing features of
Zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous and advantageous embodiments of the invention are the subject of the dependent claims.
Durch den Einsatz von Federbügeln mit unterschiedlichen Höhen zur Bildung erfindungsgemäßer Lager wirken auf das Auflageelement je nach Belastung von oben, das heißt je nach Einfederungsweg des Auflageelementes, unterschiedliche Gesamtfederkräfte auf dieses. Hierdurch lassen sich bei großen und kleinen Belastungen des Auflagelementes von oben in allen Belastungszuständen relativ kleine Einfederungswege erreichen.Through the use of spring clips with different heights to form inventions bearing act on the support element depending on the load from above, that is depending on Einfederungsweg of the support element, different total spring forces on this. As a result, can be achieved at high and small loads of the support element from above in all load conditions relatively small compression travel.
Durch eine entgegengerichtete, gegenseitige Verspannung zwischen einzelnen Federbügeln lassen sich bei erheblich variierenden Lagerbelastungen besonders gute Schwingungs- und Körperschallisolationsergebnisse bei einer insgesamt überraschend geringen Lagerverformung, das heißt geringen Einfederungswegen erzielen.By opposing, mutual tension between individual spring clips can be achieved with significantly varying bearing loads particularly good vibration and structure-borne sound insulation results at a total of surprisingly low bearing deformation, ie low compression travel.
Die einzelnen Lager bestehen zweckmäßigerweise jeweils aus einem Paar untereinander zusammenwirkender, unterschiedlich hoher Federbügel. Dabei können die Federbügel vorteilhafterweise ineinanderliegen, sowie insbesondere miteinander verbunden, beispielsweise verschraubt sein.The individual bearings expediently each consist of a pair of mutually interacting, different levels of spring clip. In this case, the spring clip can advantageously be in one another, and in particular connected to each other, for example, be screwed.
Die Federbügel liegen in Richtung von deren aufrechter Ω-Achse zweckmäßigerweise ineinander.The spring clip are in the direction of the upright Ω-axis expediently into each other.
Als besonderer Vorteil hat es sich erwiesen, einzelne Federbügel mit unterschiedlichen Federkonstanten auszubilden. Bevorzugt sollten diejenigen Federbügel, deren Höhe in vorgespanntem Zustand geringer als im entspannten Zustand ist, eine gegenüber den anderen Federbügeln, deren Höhe in vorgespanntem Zustand größer als in entspanntem Zustand ist, kleinere Federkonstante besitzen.It has proven to be a particular advantage to design individual spring clips with different spring constants. Preferably, those spring clips, the height of which in the prestressed state is lower than in the relaxed state, should have a smaller spring constant than the other spring clips whose height in the prestressed state is greater than in the relaxed state.
Durch eine gegenseitige Verdrehung der einzelnen Federbügel gegenüber deren jeweiliger aufrechten Achse innerhalb eines Lagers besitzt ein derart ausgebildetes Lager eine gute Querstabilität, einschließlich guter schwingungs- und körperschallisolierender Eigenschaften auch in Richtung der senkrecht zu der aufrechten Achse liegenden Ebene.By a mutual rotation of the individual spring clips with respect to their respective upright axis within a bearing such a bearing has a good lateral stability, including good vibration and structure-borne noise insulating properties also in the direction perpendicular to the upright axis plane.
Es können jeweils eine Vielzahl an Federbügeln zu einem gemeinsamen Bauelement zusammengefasst sein. Dabei können die einzelnen Federbügel in der Form eines mehrere einzelne Federbügel umfassenden Federbandes ausgebildet sein oder es können auch einzelne Federbügel auf beispielsweise einem streifenförmigen Verbindungselement befestigt und zusammen mit diesem montierbar sein.It can be summarized in each case a plurality of spring clips to a common component. In this case, the individual spring clips may be formed in the form of a plurality of individual spring clips comprehensive spring band or it may also be fixed individual spring clips on, for example, a strip-shaped connecting element and be mounted together with this.
Erfindungsgemäße Lager können bei einer besonders vorteilhaften Ausbildung jeweils zwei Federbügel umfassen, die durch Drehung um ihre jeweils aufrechte Achse senkrecht zueinander angeordnet sind. Bei einer ineinanderliegenden Anordnung mindestens zweier Federbügel können diese in ihren geschlossenen Zenitbereichen miteinander verschraubt sein.In a particularly advantageous embodiment, bearings according to the invention can each comprise two spring clips, which are arranged perpendicular to one another by rotation about their respective upright axis. In a nested arrangement of at least two spring clips they can be screwed together in their closed zenith areas.
Als Material für die erfindungsgemäßen Federbügel eignet sich insbesondere Stahl.As a material for the spring clip according to the invention is particularly suitable steel.
Die Federbügel können als tragende Strukturbauteile in die Auflagerelemente integriert sein.The spring clips can be integrated as load-bearing structural components in the support elements.
Die Federbügel können mit zusätzlichen anderen Schwingungs- und/oder körperschallisolierenden Mitteln zusammenwirken.The spring clip can cooperate with additional other vibration and / or structure-borne sound insulating means.
Die erfindungsgemäßen Federbügel können eine derartige mechanische Stabilität, insbesondere bei Verwendung in einem Strukturverbund, aufweisen, dass sie bei einem Einsatz als Lager für einen Boden eines Fahrzeuges in Fahrzeughochachse lediglich in einem Raum unterhalb des zu isolierenden Bodens angebracht werden müssen. Es sind hier also keine seitlichen Abstützungen wie sie bei Auflagern aus Elastomeren üblicherweise eingesetzt werden müssen, erforderlich.The spring clips according to the invention can have such a mechanical stability, in particular when used in a structural composite, that when used as a bearing for a floor of a vehicle in the vehicle vertical axis they only have to be mounted in a space below the floor to be insulated. So here are no lateral supports as they usually have to be used in supports made of elastomers required.
Ein besonderer Vorteil der Erfindung besteht ferner darin, dass die Federbügel, insbesondere in der Ausbildung eines mehrere Federbügel umfassenden Strukturteiles form- und materialmäßig für eine Isolierung tiefer Frequenzen ausgelegt werden können.A particular advantage of the invention further consists in that the spring clip, in particular in the formation of a plurality of spring clips comprising structural part shape and material can be designed for isolation of low frequencies.
Die fahrzeugseitige Bodenaufnahme für die Lager kann ein geschlossener Unterboden oder auch eine Fahrzeugrahmenkonstruktion sein.The vehicle-side floor mount for the bearings may be a closed underbody or a vehicle frame construction.
Bei einer Integration der Federbügel in den Boden eines Fahrzeuges kann dieser Boden beispielsweise als eine Verbund- bzw. Sandwichplatte mit den Federbügeln ausgebildet sein. Sofern die Federbügel nicht integraler Bestandteil des aufzulagernden Auflageelementes, d.h. insbesondere des Fahrzeugbodens sind, sind sie jeweils fest mit diesem und dem aufnehmenden Träger des Fahrzeuges zu verbinden. Dies kann beispielsweise durch Schraubverbindungen äußerst rationell und funktionell sicher erfolgen.In an integration of the spring clip in the floor of a vehicle, this floor may be formed, for example, as a composite or sandwich plate with the spring clips. If the spring clips are not an integral part of the Auflagagernden support element, ie in particular of the vehicle floor, they are each firmly connected to this and the receiving carrier of the vehicle. This can For example, by screw extremely rational and functionally safe done.

Auf einem Träger 1 eines nicht dargestellten Fahrzeuges ist ein plattenförmig ausgebildeter Boden über zu rillenförmigen Federbändern 3 zusammengefaßte Ω-förmige Federbügel 4 schwingungs- und körperschallisoliert gelagert.On a
Die Federbänder 3 mit den einzelnen Ω-förmigen Federbügeln 4 bestehen aus Federstahl. Auf dem Träger 1 sind die einzelnen Federbänder 3 jeweils beabstandet parallel und senkrecht zueinander verlaufend angeordnet. Gegenüber einer mit dem Träger 1 fest verbundenen Seitenwand 5 des Fahrzeuges ist der Boden 2 mechanisch nicht abgestützt. Ein hier vorzusehender Abstand zwischen dem Boden 2 und der Seitenwand 5 wird lediglich mit einer die Seitenbewegung des Bodens 2 nicht behindernden Abdeckung versehen, die lediglich ästhetische und schmutzabweisende Funktion besitzt.The
Durch eine material- und formmäßige Auslegung der Federbänder 3 mit einem hierfür in Frage kommenden für einen Fachmann geläufigen Fachwissen kann auf einfache Weise eine mechanisch stabile Auflagerung des Bodens 2 bereits grundsätzlich erreicht werden bei einer gleichzeitig hervorragenden Schwingungs- und Köperschallisolierung in einem insbesondere tiefen Frequenzbereich. Die Befestigung der Federbänder 3 an einerseits dem Boden 2 und andererseits dem Träger 1 kann in einfacher Weise über bei der Montage des Bodens 2 anzubringende Schrauben erfolgen.By a material and shape design of the
Ein aus zwei ineinanderliegenden, Ω-förmigen Federbügeln, nämlich einem ersten Federbügel 4' und einem zweiten Federbügel 4", aufgebautes Lager 6 ist fest auf einen Träger 1 aufgeschraubt. Bei einem Schienenfahrzeug können an diesem Träger 1 beispielsweise die Fahrzeugräder gelagert sein. Die feste Verbindung besteht über ein streifenförmiges Band 7, an dem die Federbügel 4', 4" mehrerer Lager 6 befestigt sein können und eine Verschraubung des streifenförmigen Bandes 7 mit dem Träger 1.A
Die beiden Federbügel 4' und 4" sind in dem Lager 6, das sie bilden senkrecht zueinander angeordnet. Die Federbügel 4', 4" besitzen eine Ω-artige Form, das heißt es liegt eine U-förmige Grundform mit Z-förmig ausgebildeten U-Schenkeln vor. Dadurch ergibt sich bei elastischem Material, beispielsweise Federstahl, eine Federwirkung in Richtung der aufrechten Achse eines Ω-artig geformten Federbügels 4', 4''.The two
In ihrem Zenit berühren sich die Federbügel 4', 4" eines Lagers 6 und sind dort miteinander verschraubt. In verschraubten Zustand der Federbügel 4', 4'', das heißt bei funktionsfähigem Zustand des aus diesen Federbügeln 4', 4'' bestehenden Lagers 6, sind die beiden Federbügel 4', 4" gegeneinander verspannt. Bei dem gezeichneten Lager 6 ist bei dem ersten Federbügel 4' in verbautem Zustand die Federhöhe L geringer als die Federhöhe h1 vor dem Einbau. Bei dem zweiten Federbügel 4" ist dies genau umgekehrt, das heißt in verbautem Zustand liegt mit h2 eine gegenüber 1 verringerte Federhöhe vor. Dadurch ist in dem dargestellten Lager der erste Federbügel 4' gestaucht, während der zweite Federbügel 4" gestreckt ist.At their zenith, the
Der gestreckte untere Federbügel 4" besitzt bei einer Ausbildung der beiden Federbügel 4', 4" mit unterschiedlichen Federkonstanten zweckmäßigerweise die größere Federkonstante, das heißt, der erste Federbügel 4' ist dann weicher als der zweite Federbügel 4" ausgelegt. Unterschiedliche Federkonstanten können bei den beiden Federbügeln 4' und 4" durch unterschiedliche Materialeigenschaft und/oder Formgebung bewirkt werden. Beispielsweise können unterschiedlich breite Federbügel oder formgleiche Federbügel mit unterschiedlicher Materialdicke verwendet werden.The elongated
Während in dem Ausführungsbeispiel ein Lager 6 mit lediglich zwei Federbügeln 4', 4" dargestellt ist, kann ein solches Lager grundsätzlich aus einer Vielzahl derartiger Federbügel 4', 4'' mit gegebenenfalls unterschiedlichen Federkonstanten aufgebaut sein.While in the embodiment, a
Für eine vorteilhafte Handhabung können streifenförmige Bändern 7 vorgefertigte Lager 6 besitzen und damit als streifenförmiges Band 7 mit einer Vielzahl an Lagern 6 verbaut werden. Dabei kann es zweckmäßig sein, die einzelnen Federbügel 4', 4" eines Lagers 6 in deren Zenit bereits fest miteinander zu verbinden. Grundsätzlich ist es allerdings auch möglich, die feste Verbindung im Zenit der Federbügel 4', 4" erst bei der Verbindung mit einem Auflageelement herzustellen. Sind die Federbügel 4', 4" bereits in ihren Zeniten fest miteinander verbunden, bevor eine Verbindung mit den Auflageelementen erfolgt, so ist das Lager 6 mit einer Befestigungseinrichtung zum Befestigen des Auflageelementes 2 zu versehen.For advantageous handling strip-
