Description

Die Erfindung betrifft ein Federelement nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a spring element according to the closer defined in the preamble of claim 1.

Ein Federelement dieser Art ist in der DE 701 3793 U beschrieben. Das vorbekannte Federelement dient zur elastischen Lagerung von Verbrennungsmotoren in Fahrzeugen. Dabei soll in vertikaler und in der Drehrichtung des Motors eine weiche Federkennung vorhanden sein, in Fahrtrichtung soll das Federelement jedoch hart genug sein, um die am Motor wirkenden Brems- und Verzögerungskräfte ohne größere Verformung aufzunehmen.A spring element of this type is in the DE 701 3793 U described. The previously known spring element is used for elastic mounting of internal combustion engines in vehicles. It should be present in the vertical and in the direction of rotation of the engine, a soft spring rate, in the direction of travel, however, the spring element should be hard enough to absorb the braking and deceleration forces acting on the engine without major deformation.

Das aus mehreren parallel nebeneinander liegenden Federblättchen gebildete Federelement verbindet hierzu die Federeigenschaften von Blattfedern mit den Dämpfungseigenschaften von Dämpfungsgliedern aus Gummi, die zwischen den einzelnen Federblättchen angeordnet sind.The spring element formed by a plurality of parallel juxtaposed spring leaves for this purpose combines the spring properties of leaf springs with the damping properties of rubber dampers, which are arranged between the individual spring leaflets.

In der EP 0 368 730 B1 ist ebenfalls ein elastisches Lager mit unterschiedlichen Steifigkeiten in Richtung der drei orthogonalen Achsen beschrieben.In the EP 0 368 730 B1 is also described an elastic bearing with different stiffnesses in the direction of the three orthogonal axes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Federelement zur elastischen Lagerung zu schaffen, das in eine der drei orthogonalen Achsen nahezu keine Bewegung ermöglicht bzw. eine sehr hohe Steifigkeit und nahezu keine Federeigenschaften besitzt.The present invention has for its object to provide a spring element for elastic support, which allows almost no movement in one of the three orthogonal axes or has a very high rigidity and almost no spring properties.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil von Anspruch 1 genannten Merkmale gelöst.According to the invention this object is achieved by the features mentioned in the characterizing part of claim 1.

Erfindungsgemäß wird das Federelement mit den Federblättchen, Dämpfungsgliedern und Versteifungsblechen in ein Gehäuse eingepresst. Die Einpressung ist dabei durch die komprimierbaren Dämpfungsglieder möglich, wobei die dazwischen liegenden Versteifungsbleche entsprechend für eine hohe Steifigkeit sorgen und damit eine Federung quer zur Längsrichtung der Federblättchen unterbinden. In Längsrichtung der Federblättchen sind in geringem Umfang Bewegungen möglich. In X-Richtung, d. h. quer zur Längsrichtung der Federblättchen, können große Kräfte aufgenommen werden. Gleiches gilt für Momente, um die Hochachse (Z-Achse).According to the invention, the spring element with the spring leaves, damping elements and stiffening plates is pressed into a housing. The insertion is possible by the compressible damping members, wherein the stiffening plates located therebetween accordingly provide a high rigidity and thus prevent suspension transverse to the longitudinal direction of the spring leaves. In the longitudinal direction of the spring leaves movements are possible to a small extent. In the X direction, d. H. transverse to the longitudinal direction of the spring leaves, large forces can be absorbed. The same applies to moments around the vertical axis (Z-axis).

Darüber hinaus können Verdrehtoleranzen um die X-Achse ausgeglichen werden.In addition, twist tolerances around the X-axis can be compensated.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind nachfolgend anhand des in der Zeichnung beschriebenen Ausführungsbeispiels beschrieben.Advantageous embodiments and further developments of the invention are described below with reference to the embodiment described in the drawing.

Es zeigt:It shows:

1 eine perspektivische Ansicht des erfindungsgemäßen Federelementes 1 a perspective view of the spring element according to the invention

2 einen Querschnitt durch das Federelement nach der 1. 2 a cross section through the spring element after the 1 ,

Das Federelement weist eine Vielzahl von parallel nebeneinander liegenden Federblättchen 1 auf. Die nebeneinander liegenden Federblättchen 1 sind durch einen quer zur Längsrichtung der Federblättchen 1 liegenden Quersteg 2 miteinander verbunden, um eine Biegung der Federblättchen 1 zu unterbinden. Der Quersteg 2 liegt hierzu mittig in der Längsachse der Federblättchen 1.The spring element has a plurality of parallel adjacent spring leaves 1 on. The adjacent spring leaves 1 are through a transverse to the longitudinal direction of the spring leaves 1 lying crosspiece 2 interconnected to a bend of the spring leaflets 1 to prevent. The crossbar 2 for this purpose lies centrally in the longitudinal axis of the spring leaves 1 ,

An beiden Längsseiten der Federblättchen 1 sind diese von elastisch komprimierbaren Dämpfungsgliedern 3 in Blattform umgeben. Die Dämpfungsglieder 3 können aus einem Elastomer bestehen.On both long sides of the spring leaves 1 these are of elastically compressible attenuators 3 surrounded in leaf form. The attenuators 3 can be made of an elastomer.

Jeweils zwischen zwei benachbart zueinander liegenden Dämpfungsgliedern 3 ist ein Zwischenraum vorhanden. In den Zwischenräumen sind Versteifungsbleche 4 angeordnet. Das Paket aus den Federblättchen 1, den Dämpfungsgliedern 3 und den Versteifungsblechen 4; die das Federelement bilden, wird in ein rechteckiges Gehäuse 5 eingepresst. Hierfür ist das Federelement quer zur Längsachse des Gehäuses 5 (X-Richtung gemäß 1) breiter als die Breite des Gehäuses 5. Dies bedeutet, das Federelement kann nur durch eine entsprechende Komprimierung der Dämpfungsglieder 3 in das Gehäuse 5 in Pfeilrichtung A (Y-Achse) eingeschoben werden.In each case between two mutually adjacent attenuators 3 there is a gap. In the interstices are stiffening plates 4 arranged. The package from the spring leaves 1 , the attenuators 3 and the stiffening sheets 4 ; which form the spring element, is in a rectangular housing 5 pressed. For this purpose, the spring element is transverse to the longitudinal axis of the housing 5 (X-direction according to 1 ) wider than the width of the housing 5 , This means that the spring element can only by a corresponding compression of the attenuators 3 in the case 5 in the direction of arrow A (Y-axis) are inserted.

Wie aus der 2 ersichtlich ist, ist das Gehäuse 5 auf seiner Oberseite und auf seiner Unterseite mit Längsnuten 6 versehen. In die Längsnuten 6 werden nach Komprimierung des Federelements zum Einschieben in das Gehäuse 5 die Versteifungsbleche 4 eingeschoben. Hierzu besitzen die Längsnuten 6 entsprechend mit Spiel die gleiche Breite wie die Dicke der Versteifungsbleche 4. Auf diese Weise sind die Versteifungsbleche 4 in dem Gehäuse 5 entsprechend geführt.Like from the 2 it can be seen, is the housing 5 on its top and on its underside with longitudinal grooves 6 Mistake. In the longitudinal grooves 6 are after compression of the spring element for insertion into the housing 5 the stiffening sheets 4 inserted. For this purpose have the longitudinal grooves 6 according to match the same width as the thickness of the stiffening plates 4 , In this way, the stiffening plates 4 in the case 5 guided accordingly.

An beiden Enden der Federblättchen 1, die aus dem Gehäuse 5 herausragen, ist jeweils ein Halter bzw. Träger 7 für die Federblättchen 1 vorgesehen. Über die Halter 7 erfolgt der Einbau des Federelements an einer gewünschten Stelle zur elastischen Lagerung einer Einrichtung, Vorrichtung oder dergleichen.At both ends of the spring leaves 1 coming out of the case 5 each protrude, is a holder or carrier 7 for the spring leaves 1 intended. About the holders 7 the installation of the spring element at a desired location for elastic mounting of a device, device or the like.

Durch die komprimierte Lagerung des Federelementes in dem Gehäuse 5 ist das Federelement in X-Richtung sehr steif. In Y-Richtung ist jedoch eine geringe Verschiebung möglich. Um die Z-Achse (Hochachse) ist ebenfalls eine hohe Steifigkeit gegeben, sodass um die Z-Achse große Momente aufgenommen werden können.By the compressed storage of the spring element in the housing 5 the spring element is very stiff in the X direction. In the Y direction, however, a small shift is possible. Around the Z axis (Vertical axis) is also given a high rigidity, so that large moments can be taken around the Z-axis.
