Abstract
Description
Die Erfindung bezieht sich auf ein Federbein nach dem Oberbegriff des Anspruchs 1.The invention relates to a shock absorber according to the preamble of Claim 1.
Es ist eine Luftfeder-Dämpfer-Einheit aus der DE-OS 32 21 850 bekannt, die aufbauseitig in einem elastischen Lagerelement gehalten wird. An diesem ist die Kolbenstange des Dämpfers sowie eine Gehäusekappe der Luftfeder abgestützt, so daß sowohl die Tragkräfte als auch die Dämpferkräfte über diese Lagerelement aufgenommen werden, was zu nachteiligen statischen Vorspannungen des Lagerelements durch die Tragkräfte führt und eine genaue Abstimmung des elastischen Lagerelements auf die tatsächlichen Einzelkräfte erschwert.There is an air spring damper unit known from DE-OS 32 21 850, the is held on the body side in an elastic bearing element. On this is the piston rod of the damper and a housing cap of the air spring supported so that both the load capacities and the damper forces over these bearing element are included, resulting in adverse static The bearing element is preloaded by the load-bearing forces and accurate Matching the elastic bearing element to the actual individual forces difficult.
Aufgabe der Erfindung ist es, eine Abstützung für eine Luftfeder-Dämpfer- Einheit zu schaffen, die eine optimale Abstimmung des elastischen Lager elements gewährleistet und deren Verwendung innerhalb der Luftfeder eine Abdichtung der Druckkammer vereinfacht und darüber hinaus auch eine Entlastung des elastischen Lagerelements ermöglicht.The object of the invention is to provide a support for an air spring damper To create unity that optimal adjustment of the elastic bearing elements guaranteed and their use within the air spring a Sealing of the pressure chamber simplified and also a Relief of the elastic bearing element allows.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausbildungen der Erfindung beinhalten die Unteransprüche.This object is achieved by the characterizing features of Claim 1 solved. Further advantageous developments of the invention include the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß durch die getrennte Abstützung der Trag- und Dämpferkräfte der Dämpfer in einem speziell an die tatsächlich auftretenden Einzelkräfte angepaßten elastischen Lagerelement gehalten wird. Es ist somit nur eine relativ geringe Vorspannung des Lagerelements erforderlich. Gleichzeitig ermöglicht es die umfangsseitig eingeklemmte Anordnung des elastischen Lagerelements im Kappenendstück, dieses Element als dichtendes Teil zu verwenden, so daß zusätzliche Dichteinrichtungen und Mittel entfallen. The main advantages achieved with the invention are that due to the separate support of the load and damper forces of the damper in a specially adapted to the actually occurring individual forces elastic bearing element is held. It is therefore only a relative one low preload of the bearing element required. Allows at the same time it the circumferentially clamped arrangement of the elastic bearing element in the cap end piece to use this element as a sealing part, so that additional sealing devices and means are omitted.
In einer weiteren Ausführungsform des Federbeines ist oberhalb des elastischen Lagerelements eine mit der Druckkammer verbundene Luftkammer angeordnet. Hierdurch wird eine beidseitige Druck beaufschlagung des elastischen Lagerelements möglich.In a further embodiment of the strut is above the elastic bearing element connected to the pressure chamber Air chamber arranged. This creates a two-sided print loading of the elastic bearing element possible.
Ausführungsbeispiele der Erfindung sind in den Zeichnungen darge stellt und werden im folgenden näher beschrieben. Es zeigtEmbodiments of the invention are shown in the drawings represents and are described in more detail below. It shows
Fig. 1 eine Feder-Dämpfer-Einheit im Schnitt, Fig. 1 is a spring-damper unit in section,
Fig. 2 eine weitere Ausführungsform einer Luftfeder-Dämpfer-Einheit im Schnitt mit einer zusätzlichen Luftkammer, und Fig. 2 shows another embodiment of an air spring damper unit in section with an additional air chamber, and
Fig. 3 eine weitere Ausführung einer Feder-Dämpfer-Einheit im Schnitt, die drehbar am Fahrzeugaufbau gehalten ist. Fig. 3 shows another embodiment of a spring-damper unit in section, which is rotatably held on the vehicle body.
Das Federbein 1 umfaßt eine zu einer Einheit zusammengefaßte Luftfeder 2 mit Dämpfer 3, die so zueinander angeordnet und ausgebildet sind, daß die Tragkräfte T und die Dämpferkräfte D getrennt abstützbar sind.The shock absorber 1 comprises an air spring 2 with a damper 3 , which is combined to form a unit, and which are arranged and designed with respect to one another in such a way that the carrying forces T and the damper forces D can be supported separately.
Der Dämpfer 3 besteht im wesentlichen aus einem hydraulischen Arbeits zylinder 4, der von einer Luftfeder 2 umgeben ist. Diese weist zwischen dem Zylindermantel 5 und einer Gehäusekappe 6 eine Druckkammer 7 auf, die von einem flexiblen Balg 21 umschlossen ist.The damper 3 consists essentially of a hydraulic working cylinder 4 , which is surrounded by an air spring 2 . This has a pressure chamber 7 between the cylinder jacket 5 and a housing cap 6 , which is enclosed by a flexible bellows 21 .
Die Gehäusekappe 6 der Luftfeder 2 stützt sich an einem Aufbau teil 8 des Fahrzeugs ab. Sie ist über den Abstützbereich 13 am Fahrzeug aufbau herausgeführt und hält an ihrem freien Ende 9 ein elastisches Lager element 10. Dies ist umfangsseitig eingeklemmt und mit relativ geringer Vorspannung bei einer axialen Beweglichkeit im Kappenendstück 14 gehalten. An diesem Lagerelement 10 stützt sich das Federbein 1 über die Kolbenstange 11 des Arbeitszylinders 4 ab.The housing cap 6 of the air spring 2 is supported on a body part 8 of the vehicle. It is led out via the support area 13 on the vehicle body and holds an elastic bearing element 10 at its free end 9 . This is clamped on the circumference and held in the cap end piece 14 with a relatively low pretension with an axial mobility. The strut 1 is supported on this bearing element 10 via the piston rod 11 of the working cylinder 4 .
Die Gehäusekappe 6 wird über einen Absatz 12, der eine Verringerung des unteren Kappendurchmessers bewirkt, vom Aufbauteil 8 getragen. Es wäre auch eine andere Ausbildung zur Abstützung der Gehäusekappe 6 , wie z. B. einen Flansch od. dgl. möglich. The housing cap 6 is carried by the mounting part 8 via a shoulder 12 , which brings about a reduction in the lower cap diameter. It would also be another training for supporting the housing cap 6 , such as. B. a flange. Like. Possible.
Das Lagerelement 10 ist in der Weise eingespannt im Kappenendstück 14 gehalten, daß es gleichzeitig eine Dichtfunktion erfüllen kann.The bearing element 10 is held in the cap end piece 14 in such a way that it can simultaneously fulfill a sealing function.
Nach einer weiteren Ausführung der Erfindung gemäß Fig. 2 ist die Druck kammer 7 der Luftfeder 2 mit einer oberhalb des Lagerelements 10 ange ordneten Luftkammer 15 verbunden, die von einem Deckel 16 abgeschlossen ist. Dieser wird mit der Gehäusekappe 6 am Kappenendstück 14 verbunden. Die luftüberleitende Verbindung zwischen den beiden Kammern 15 und 17 erfolgt mittels Öffnungen 17 in einer Wand 18 der Haltekonsole 19 für das Lagerelement 10. Hierdurch wird die Verspannung des Dämpferlagers 10 klein gehalten und eine optimierte Aufnahme von Dämpferkräften erzielt.According to a further embodiment of the invention according to FIG. 2, the pressure chamber 7 of the air spring 2 is connected to an air chamber 15 arranged above the bearing element 10 , which is closed by a cover 16 . This is connected to the housing cap 6 on the cap end piece 14 . The air-conducting connection between the two chambers 15 and 17 takes place by means of openings 17 in a wall 18 of the holding bracket 19 for the bearing element 10 . As a result, the tensioning of the damper bearing 10 is kept small and an optimized absorption of damper forces is achieved.
Nach einer weiteren Ausführung der Erfindung gemäß Fig. 3 kann das Feder bein 1 in den Ausführungen gemäß der Fig. 1 und 2 drehbar am Aufbauteil 8 des Fahrzeugs gehalten sein. Die Gehäusekappe 6 ist hierzu über ein Lagerelement 20 zur Aufbauwand 8 hin abgestützt.According to a further embodiment of the invention according to FIG. 3, the spring leg 1 in the embodiments according to FIGS. 1 and 2 can be rotatably held on the body part 8 of the vehicle. For this purpose, the housing cap 6 is supported by a bearing element 20 towards the structural wall 8 .
