Abstract

A spring strut for vehicles with an air spring and a damper is described. The damper comprises a piston, working in a cylinder, the piston rod of which is held in an elastic bearing element. Between the cylinder and a housing cap, a pressure chamber of the air spring is formed, sealed off by means of a flexible bellows. The housing cap of the air spring is held on the vehicle body and the piston rod of the damper is supported separately from the air spring in an elastic element mounted on the rigid housing cap. The housing cap which has a support area designed as a shoulder, which is directly connected to the vehicle body, is used as abutment for the air spring. The elastic bearing element, which at the same time seals off the pressure chamber of the air spring, is held, clamped by its circumference, in a cap end piece extended out over this body-side area.

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.

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.
