Description
Technisches GebietTechnical area
Die vorliegende Erfindung befasst sich mit einem Dämpferlager aus einem Innenmetall und einer denselben umgebenden Elastomerfeder, insbesondere für die Anbindung einer Stoßdämpfer-Kolbenstange an die Karosserie eines Kraftfahrzeugs.The present invention is concerned with a damper bearing made of an inner metal and a surrounding elastomer spring, in particular for the connection of a shock absorber piston rod to the body of a motor vehicle.
Dämpferlager der voranstehenden Art sind weit verbreitet und in unterschiedlichen Ausführungsformen auf dem Markt. Sie dienen zur elastischen Lagerung von Achslenkern und anderen Aggregaten in Kraftfahrzeugen. Unter anderem auch für die Anbindung der Stoßdämpfer-Kolbenstange an die Karosserie des Kraftfahrzeugs.Damper bearings of the above type are widely used and in different embodiments in the market. They serve for the elastic storage of axle links and other units in motor vehicles. Among other things, for the connection of the shock absorber piston rod to the body of the motor vehicle.

Eine andere Möglichkeit eines sehr einfachen Dämpfungslagers zeigt die
Darstellung der ErfindungPresentation of the invention
Die Entwicklung bei der Herstellung von Kraftfahrzeugen verlangt neben sicherer und guter Dämpfung auch eine möglichst kompakte Ausführung des Dämpferlagers. Dabei ist der für das Dämpferlager vorgesehene Bauraum äußerst beschränkt. Der zur Verfügung stehende Bauraum für Federbeine ist insbesondere in Fahrzeug-Querrichtung bei vielen Fahrzeugen stark reduziert. Dabei wird eine belastungsgerechte Größe für das Dämpferlager jedoch weiterhin benötigt. Der Erfindung liegt die deshalb die Aufgabe zugrunde, ein Dämpferlager zu schaffen, dass einen möglichst einfachen Aufbau hat, eine gute Fertigung erlaubt, sowie eine gute Montage, wobei der für das Dämpferlager benötigte Bauraum auf ein Minimum reduziert ist, ohne die Wirkungsweise des Dämpferlagers zu beinträchtigen.The development in the manufacture of motor vehicles requires not only safe and good damping but also a compact design of the shock absorber bearing. In this case, the space provided for the damper bearing space is extremely limited. The available space for struts is greatly reduced, especially in vehicle transverse direction in many vehicles. However, a load-appropriate size for the damper bearing is still required. The invention is therefore the object of the invention to provide a damper bearing that has the simplest possible structure, a good production allowed, and a good installation, the space required for the damper bearing space is reduced to a minimum, without the operation of the damper bearing affect.
Die Lösung der gestellten Aufgabe wird mit den Merkmalen des Anspruchs 1 bzw. des Anspruchs 2 erreicht. Die Unteransprüche 2 bis 8 stellen vorteilhafte Weiterbildungen des Erfindungsgegenstandes dar.The solution of the problem is achieved with the features of claim 1 and
Um eine möglichst kompakte Bauweise des Dämpferlagers zu erreichen, wird das Dämpferlager dem Bauraum angepasst. Das bedeutet, dass das Dämpferlager unterschiedliche Außenmaße (A/a) in den Richtungen der seitlichen Kräfte (X/Y) hat. Dadurch kann eine Anpassung an einen eingeschränkten Bauraum erfolgen. Die Elastomerfeder kann in den verschiedenen Richtungen der Krafteinwirkung (X/Y) unterschiedliche Dicken (D/d) haben. Dadurch können richtungsabhängig unterschiedliche Steifigkeitsanforderungen erfüllt werden. Besonders vorteilhaft ist es wenn das Innenmetall des Dämpferlagers in den verschiedenen Richtungen der Krafteinwirkung (X/Y) mit unterschiedlichen Dicken (E/e) versehen wird. Das Innenmetall wird aus einem Kern gebildet, der vorzugsweise aus Stahl oder Aluminium besteht. Möglich ist auch ein Stahl-Kunststoff-Verbund. Durch die vorgenommenen Maßnahmen erhält das Dämpferlager einen ovalen Querschnitt.In order to achieve a compact design of the shock absorber bearing, the damper bearing is adapted to the space. This means that the damper bearing has different outer dimensions (A / a) in the directions of the lateral forces (X / Y). This can be done to adapt to a limited space. The elastomeric spring may have different thicknesses (D / d) in the different directions of force (X / Y). As a result, different stiffness requirements can be met depending on the direction. It is particularly advantageous if the inner metal of the damper bearing is provided with different thicknesses (E / e) in the different directions of the action of force (X / Y). The inner metal is formed from a core, which preferably consists of steel or aluminum. Also possible is a steel-plastic composite. By the measures taken, the damper bearing receives an oval cross-section.
Das Innenmetall kann als Gussteil hergestellt werden, auf den sodann die Elastomerfeder aufvulkanisiert wird. Eine besonders günstige Ausführungsform, sowohl fertigungstechnisch als auch kostenmäßig sieht jedoch vor, dass das Innenmetall aus einem Blechteil gebildet wird. Dabei kann das Blechteil aus einem Röhrenteil und zwei davon abstehenden Flanschscheiben bestehen. Zur Verstärkung des Innenmetalls bzw. Fixierung eines axialen Anschlagpuffers kann das die innere Befestigungsöffnung umgebende Flanschteil durch ein Stützblech verstärkt sein.The inner metal can be produced as a casting on which then the elastomer spring is vulcanized. However, a particularly favorable embodiment, both in terms of manufacturing technology and cost, provides that the inner metal is formed from a sheet metal part. In this case, the sheet metal part may consist of a tube part and two flange plates projecting therefrom. To reinforce the inner metal or fixation of an axial stop buffer, the flange part surrounding the inner fastening opening can be reinforced by a support plate.
Sowohl bei dem einteiligen Metallkern als auch bei dem aus mehreren Blechteilen bestehenden Metallkern werden die freien Flächen des Metallkerns vom Elastomer bei der Vulkanisation überdeckt.Both in the one-piece metal core as well as in the metal core consisting of several sheet metal parts, the free surfaces of the metal core are covered by the elastomer during vulcanization.
In weiterer Ausgestaltung kann das Dämpferlager mit axialen Anschlagpuffern versehen sein. Diese Anschlagpuffer sind an den axialen Wandteilen des Metallkerns angebracht. Des Weiteren kann das Dämpferlager mit einer rundumlaufenden elastomeren Wulst versehen sein. Schließlich kann das gesamte Dämpferlager wie bekannt, von einer Außenhülse eingefasst werden, welche an die ovale Form des Dämpferlagers angepasst ist.In a further embodiment, the damper bearing can be provided with axial stop buffers. These bumpers are attached to the axial wall portions of the metal core. Furthermore, the damper bearing can be provided with a circumferential elastomeric bead. Finally, as is known, the entire damper bearing can be enclosed by an outer sleeve, which is adapted to the oval shape of the damper bearing.
