Abstract
Description
Die Erfindung betrifft ein Lagerelement mit einem elastomeren Tragkörper nach dem Oberbegriff nach Patentanspruch 1.The The invention relates to a bearing element with an elastomeric support body according to the preamble of claim 1.
Derartige Lagerelemente sind allgemein bekannt und werden beispielsweise im Kraftfahrzeugbau eingesetzt, um miteinander verbundene Bauteile voneinander zu entkoppeln. Derartige Lagerelemente finden beispielsweise Anwendung in Federblöcken, in Achslagern und Motorlagern.such Bearing elements are well known and are used, for example, in Automotive engineering used to interconnected components from each other to decouple. Such bearing elements are used for example in spring blocks, in axle bearings and engine mounts.
Unter Betriebsbedingungen unterliegt der elastomere Tragkörper nicht nur mechanischen Beanspruchungen, sondern ist in der Regel auch gegenüber Umwelteinflüssen exponiert. Insbesondere kann es hierbei zu oxidativer Korrosion kommen, was zu einer Versprödung und schließlich zur Rissbildung im Tragkörper führt. Je nach Einsatzort kommt dazu eine thermische Beanspruchung, sowie eine Beanspruchung durch Spritzwasser, welches insbesondere im Winter gelöstes Streusalz enthalten kann, was die Korrosion des Tragkörpers weiter befördert.Under Operating conditions subject to the elastomeric support body not only mechanical stresses, but is usually also exposed to environmental influences. In particular, can this leads to oxidative corrosion, resulting in embrittlement and finally to cracking in the support body leads. Depending on the place of use, this is subject to thermal stress, as well as a load caused by splashing, which in particular In winter, dissolved road salt may contain what is the corrosion of the supporting body further.
Die
Der vorliegenden Erfindung liegt also die Aufgabe zugrunde, ein Lagerelement der eingangs genannten Art bereitzustellen, dessen elastomerer Tragkörper dauerhaft vor korrosiven Einflüssen geschützt ist, wobei die zum Schutz des Tragkörpers eingesetzten Mittel im Rahmen normaler Wartungsvorgänge unaufwendig ausgetauscht werden können.Of the The present invention is therefore the object of a bearing element to provide the type mentioned, the elastomeric support body permanently protected against corrosive influences is, wherein the used to protect the support body Means in the context of normal maintenance operations unaufwendig can be exchanged.
Diese Aufgabe wird durch ein Lagerelement mit den Merkmalen des Patentanspruchs 1 gelöst.These The object is achieved by a bearing element with the features of the claim 1 solved.
Ein derartiges Lagerelement umfasst einen Lagerkern und eine Lagerhülse, wobei zwischen Lagerkern und Lagerhülse ein Tragkörper aus einem Elastomer angeordnet ist. Dieser ist bereichsweise mit einer alterungsbeständigen Abdeckung versehen. Erfindungsgemäß ist nun vorgesehen, dass diese alterungsbeständige Abdeckung als Schutzkappe ausgebildet ist. Eine derartige Schutzkappe muss den Tragkörper lediglich gegen Umwelteinflüsse abschließen. Es ist dabei nicht nötig, dass die Schutzkappe selbst direkt Bestandteil des Tragkörpers oder auch unmittelbar mit ihm verbunden ist. Dadurch ist der Austausch von beschädigten Schutzkappen leicht möglich.One Such bearing element comprises a bearing core and a bearing sleeve, wherein between bearing core and bearing sleeve a support body is arranged from an elastomer. This is partially with provided an age-resistant cover. According to the invention now provided that this age-resistant cover is designed as a protective cap. Such a protective cap must the Completing the support body only against environmental influences. It is not necessary that the cap itself directly Part of the supporting body or directly with him connected is. This is the replacement of damaged Protective caps easily possible.
Es ist dabei besonders vorteilhaft, wenn der Tragkörper durch die Schutzkappe vollständig luftdicht gegen die Umgebung abschließbar ist. Damit wird oxidative Korrosion des elastomeren Materials des Tragkörpers völlig vermieden. Ferner ist ebenfalls eine luftdurchlässige Verbindung von Tragkörper und Schutzkappe denkbar, wodurch Kosten eingespart werden können.It is particularly advantageous when the support body through the protective cap completely airtight to the environment is lockable. This is oxidative corrosion of the elastomeric Materials of the support body completely avoided. Further is also an air permeable connection of the support body and Protective cap conceivable, which costs can be saved.
Um einen festen Sitz der Schutzkappe zu gewährleisten ist diese bevorzugt reibschlüssig und/oder formschlüssig mit dem Tragkörper und/oder der Lagerhülse verbindbar. Zur weiteren Sicherung dieser Verbindung können dabei Spannringe vorgesehen sein, über welche die Schutzkappe am Lagerelement festlegbar ist. Diese Festlegung kann dabei sowohl im Bereich der Lagerhülse als auch im Bereich des Lagerkerns erfolgen, so dass die Schutzkappe alle freiliegenden Flächen des elastomeren Tragkörpers abschließt. Auch eine Festlegung direkt am Tragkörper ist möglich.Around ensure a tight fit of the cap these preferably frictionally and / or positively connectable to the support body and / or the bearing sleeve. To further secure this connection while clamping rings be provided, via which the protective cap on the bearing element is determinable. This definition can be used both in the area of Bearing sleeve as well as in the area of the bearing core, so that the protective cap all exposed surfaces of the concludes elastomeric support body. Also one Fixing directly on the support body is possible.
Um einen besonders guten formschlüssigen Halt zwischen Schutzkappe und Lagerelement zu gewährleisten kann weiterhin vorgesehen sein, dass die Schutzkappe einen Steg aufweist, welcher mit einer korrespondierenden Nut im Lagerelement in Eingriff bringbar ist. Auch eine inverse Ausführung, also eine Gestaltung, bei der ein Steg des Lagerelementes in eine korrespondierende Nut der Schutzkappe eingreift, ist denkbar.Around a particularly good positive connection between the protective cap and to ensure bearing element can continue to be provided be that the protective cap has a web, which with a corresponding groove in the bearing element can be brought into engagement. Also an inverse version, so a design, at a web of the bearing element in a corresponding groove of the Protective cap engages, is conceivable.
Um zu gewährleisten, dass die Schutzkappe durch Dehnung beziehungsweise Kompression des Tragkörpers nicht beschädigt wird, kann die Schutzkappe selbst aus einem elastomeren Material ausgeführt sein. Alternativ ist es möglich, die Schutzkappe zumindest bereichsweise gewellt zu gestalten, so dass durch Dehnung oder Kompression des gewellten Bereiches respondierende Bewegungen des Tragkörpers ausgeglichen werden können.To ensure that the protective cap is not damaged by stretching or compression of the support body, the cap itself can be made of an elastomeric material. Alternatively, it is possible to make the cap at least partially wavy, so that by stretching or compression of the corrugated th range responding movements of the support body can be compensated.
Im Folgenden soll anhand der Zeichnung die Erfindung und ihre Ausführungsformen näher erläutert werden. Hierbei zeigen:in the Below is the invention and its embodiments with reference to the drawing be explained in more detail. Hereby show:
