Abstract
Description
Die Erfindung betrifft eine Gelenklagerbuchse, insbesondere für einen Achslenker eines Kraftfahrzeugs, mit einem stabilen, zylindrischen Innenteil aus Metall und dazu konzentrisch nach außen angeordneten Zwischenrohr und Außenrohr, wobei zwischen Innenteil und Zwischenrohr sowie zwischen Zwischenrohr und Außenrohr jeweils eine einvulkanisierte Gummischicht angeordnet sind.The The invention relates to a spherical bearing bush, in particular for a Achslenker of a motor vehicle, with a stable, cylindrical Inner part of metal and arranged concentrically to the outside Intermediate pipe and outer pipe, between the inner part and the intermediate pipe and between the intermediate pipe and outer tube each a vulcanized rubber layer are arranged.
Derartige gummierte Gelenklagerbuchsen fallen unter den Oberbegriff Hülsengummifedern. Die zylindrische Hülsengummifeder lässt axiale, radiale, kardanische und drehende elastische Verformungen zu.such rubberized spherical bushings fall under the generic term rubber bushes. The cylindrical sleeve rubber spring leaves axial, radial, gimbal and rotating elastic deformations too.
Im Kraftfahrzeugbau ist es aus Gründen des Fahrkomforts erwünscht, die Schwingungen bei kleinen Amplituden zu isolieren. Hierzu würde sich eine weiche Federeinstellung der Gummikoppelschichten anbieten. Allerdings wird eine weiche Gummischicht bei plötzlichen großen radialen Einfederbewegungen aufgrund beispielsweise harter, auf das Chassis einwirkender Stöße beschädigt.in the Motor vehicle construction is it for reasons the ride comfort desired, to isolate the vibrations at low amplitudes. This would happen offer a soft spring adjustment of the rubber bilayers. However, a soft rubber layer will be at sudden large radial Jounce movements due to, for example, hard, on the chassis damaged shocks.
Im Kraftfahrzeugbau werden somit für ein komfortoptimiertes Fahrverhalten Gummilager benötigt, die sowohl radial als auch kardanisch in einem definierten Bereich eine weiche Federcharakteristik aufweisen, gleichzeitig aber hohe Kräfte aufnehmen müssen.in the Automotive engineering are thus for a comfort-optimized ride rubber bearing needed, the both radially and gimbalically in a defined area have soft spring characteristic, but at the same time have to absorb high forces.

Dieses Gelenklager hat schlechte kardanische Eigenschaften. Die durch die Zweiteiligkeit entstandenen beiden Gummifedern liegen außen und müssen die kardanischen Kräfte aufnehmen, so daß sich aufgrund des großen Abstandes der Gummifedern zum Lagerdrehpunkt ein hohes kardanisches Moment ergibt. Der mittige Anschlag ist für die kardanischen Kräfte kaum bedeutend, weil er bei kardanischer Beanspruchung zu nahe am Lagerdrehpunkt liegt. Durch die Zweiseitigkeit des Lageraufbaus und die innere Durchmesservergrößerung des Innenteils zum Erzielen eines Anschlages ist der Gesamtaufbau dieses Gelenklagers höchst aufwändig.This Spherical bearing has poor cardanic properties. The by the Two-piece originated two rubber springs lie outside and need the gimbal forces record, so that because of the big one Distance of the rubber springs to the bearing pivot a high gimbal moment results. The central stop is hardly for the gimbal forces significant because it is too close to the bearing pivot point when gimbaled. Due to the two - sidedness of the bearing structure and the inner diameter enlargement of the Inside to achieve a stroke, the overall design is this Joint stocks highest consuming.
Der Erfindung liegt die Aufgabe zugrunde, eine Gelenklagerbuchse der eingangs genannten Art derart auszubilden, dass ein verdrehweiches Gelenklager mit progressiver radialer Federkennlinie geschaffen wird, das auch größeren radialen und kardanischen Belastungen standhalten kann, wobei gleichzeitig der konstruktive Aufwand minimiert wird.Of the Invention is based on the object, a spherical bearing bushing of initially mentioned type in such a way that a verdrehweiches Spherical bearings created with progressive radial spring characteristic becomes, also larger radial and can withstand cardan loads while being at the same time the design effort is minimized.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die innere, zwischen Innenteil und Zwischenrohr angeordnete Gummischicht eine geringere Steifigkeit aufweist als die äußere, zwischen Zwischenrohr und Außenrohr angeordnete Gummischicht und dass auf beiden Enden des zylindrischen Innenteils auf den Außenumfang aufgebrachte Anschlagringe vorhanden sind, deren Oberflächen im Betriebspunkt des Gelenklagers zum Zwischenrohr beabstandet sind.The The object is achieved in that the inner, between inner part and intermediate tube arranged rubber layer has a lower rigidity than the outer, between the intermediate tube and outer tube arranged rubber layer and that on both ends of the cylindrical inner part on the outer circumference applied stop rings are present whose surfaces at the operating point of the hinge bearing are spaced from the intermediate tube.
Die innere Gummischicht stellt eine weiche Gummifeder dar und ist festhaftend mit dem Innenteil und dem Zwischenrohr verbunden. Die äußere Gummischicht stellt eine harte Gummifeder dar. Bei kleineren, den häufigeren Zustand darstellenden Betriebsbelastungen bestimmt sich die Federsteifigkeit des Gelenklagers aus der Reihenschaltung der beiden Gummifedern. Erst bei größeren radialen Belastungen, die zeitweise auftreten, legen sich die Anschlagringe gegen den Innenumfang des Zwischenrohrs. Dadurch wird die innere Gummifeder blockiert, d.h. wirkungslos und der weitere radiale bzw. kardanische Kennlinienverlauf des Gelenklagers wird nur noch durch die äußere Gummifeder bestimmt. Diese harte Gummifeder hat eine steilere Progression und kann die hohen Belastungen verkraften. Die weiche Gummifeder wird in diesem Fall nicht weiter beansprucht und somit geschont.The inner rubber layer is a soft rubber spring and is firmly adhered to the inner part and the intermediate tube. The outer rubber layer is a hard rubber spring. For smaller operating conditions, which represent the more frequent state, the spring stiffness of the spherical plain bearing is determined by the series connection of the two rubber springs. Only with larger radial loads, which occur at times, place the stop rings against the inner circumference of the intermediate tube. This blocks the inner rubber spring ie ineffective and the further radial or gimbal characteristic curve of the joint bearing is determined only by the outer rubber spring. This hard rubber spring has a steeper progression and can handle the high loads. The soft rubber spring is not further stressed in this case and thus spared.
In vorteilhafter Ausgestaltung der Erfindung ist die innere Gummischicht dicker und axial schmaler als die äußere Gummischicht. Dadurch ist der durch die innere Gummischicht gebildete Federkörper mit einer geringeren Steifigkeit versehen als der durch die äußere Gummischicht gebildete Federkörper.In Advantageous embodiment of the invention is the inner rubber layer thicker and axially narrower than the outer rubber layer. Thereby is the spring body formed by the inner rubber layer with a lower rigidity than provided by the outer rubber layer formed spring body.
In weiterer vorteilhafter Ausgestaltung der Erfindung bestehen die Gummischichten aus unterschiedlichen Gummimischungen, wobei die äußere Gummischicht die härtere Gummimischung aufweist. Die unterschiedlichen Federsteifigkeiten werden durch unterschiedlich harte Gummimischungen bestimmt.In further advantageous embodiment of the invention are the Rubber layers of different rubber compounds, with the outer rubber layer the harder ones Compound has rubber. The different spring stiffnesses are determined by different hard rubber compounds.
In weiterer vorteilhafter Ausgestaltung der Erfindung sind die Anschlagringe durch entsprechende Ausformung der Enden des Innenteils gebildet, wobei die Anschlagringe nicht als separate Bauteile ausgeführt werden müssen.In Another advantageous embodiment of the invention are the stop rings formed by appropriate shaping of the ends of the inner part, wherein the stop rings are not designed as separate components have to.
In weiterer vorteilhafter Ausgestaltung der Erfindung verjüngen sich die Anschlagringe in axialer Richtung umfangsmäßig konisch nach außen. Bei kardanischer Auslenkung des Gelenklagers legt sich das Ende des Zwischenrohrs flächig auf dem Außenumfang des jeweiligen Anschlagringes an.In further advantageous embodiment of the invention rejuvenate the stop rings in the axial direction circumferentially conically outward. At Cardan Deflection of the joint bearing sets the end of the intermediate tube flat on the outer circumference of the respective stop ring.
In weiterer vorteilhafter Ausgestaltung der Erfindung weist die innere Gummischicht an den axialen Enden einen Bund auf, der die Anschlagringe gegen axiales Verschieben sichert.In further advantageous embodiment of the invention, the inner Rubber layer at the axial ends of a covenant, the stop rings against axial displacement ensures.
In weiterer vorteilhafter Ausgestaltung der Erfindung ragen die Enden des Zwischenrohrs über die Anschlagringe und weisen auf ihrem Innenumfang eine Gummiauflage auf, die vorteilhafterweise aus einem Gummiüberlauf der inneren Gummischicht besteht.In further advantageous embodiment of the invention protrude the ends of the intermediate pipe over the Stop rings and have on their inner circumference a rubber pad which advantageously consists of a rubber overflow of the inner rubber layer consists.
Das erfindungsgemäße Gelenklager weist sowohl radial als auch kardanisch in einem definierten Bereich eine weiche Federcharakteristik auf, kann gleichzeitig aber auch hohe Kräfte aufnehmen, wobei die weiche Gummifeder durch die definierte Blockierung geschont wird.The Spherical bearing according to the invention has both radial and gimbal in a defined area a soft spring characteristic, but at the same time also high forces absorb, with the soft rubber spring by the defined blocking is spared.
