Abstract

The rubber spring unit with damping action comprises an annular rubber member vulcanised round an inner pipe and in a pot-shaped outer frame. Between the base of the outer frame and the member and pipe a chamber is formed. This chamber is reduced in volume when the unit is compressed. A valve can be provided, via which compressed air is delivered into the chamber, thus adjusting the capacity and spring characteristics. Damping can be effected by fluid in the chamber, forced by compression of the unit into the tube via a valve which has a throttling action on the return stroke.

Description

Beschreibung description

Bezeichnung Gummi-Luftfederelement mit Dämpfung.Designation rubber air spring element with cushioning.

Beschreibung Bei der Gusnmi-Luftfeder mit Dämpfung handelt es sich um ein Element, welches die vier wichtigsten Anforderungen, die im Bereich "Federung" gestellt sind, in sich vereint, d.h. daß es verbindet, federt, dämpft und führt. Zur Lösung dieser vier Aufgaben sind bereits eine große Anzahl von einzelnen Verbindungs-, Oder, Dämpfungs- und puhrungselementen bekannt. Sie sind aber alle von dem wesentlichen Unterschied gegenüber meiner Konstruktion gekennzeichnet, daß ein einzelnes Element jeweils nur eine oder zwei der gestellten Anforderungen erfüllt.Description The Gusnmi air spring with cushioning is an element that meets the four most important requirements in the area of "suspension" are placed, united in themselves, i.e. that it connects, bounces, dampens and guides. To solve these four tasks, a large number of individual connection, Or, known damping and puhrungselemente. But they are all of the essential Difference from my construction marked that a single element only fulfills one or two of the requirements.

Das Gummi-Luftfederelement mit Dämpfung besteht in erster Linie aus einem Gummimetallkörper bekannter Art. Er kann in verschiedenen Formen ausgeführt sein. Die Idealform ist jedoch rund. Unter Zugrundelegung der runden Form besteht dieses Element aus einem Metallrohrabschnitt als Außenrohr und aus einem im Durchmesse- kleineren Rohrabschnitt als Innenrohr. In den Raum zwischen Innenrohr und Außenrohr ist die Gummifeder einvulkanisiert. Dieses Element erfüllt bereits drei der vier Punkte. Die Federung erfolgt in Axialrichtung, die Fuh.rung radial und die Verbindung wird gewährleistet durch die Vulkanisation. Betrachtet man das Element in axial senkrechter Lage, so befindet sich ein Befestigungspunkt am Außenrohr unten und einer am Innenrohr oben.The rubber air spring element with cushioning consists primarily of a rubber-metal body of known type. It can be designed in various forms be. However, the ideal shape is round. Based on the round shape there is this element consists of a metal pipe section as the outer pipe and of a diameter smaller pipe section than inner pipe. In the space between the inner pipe and the outer pipe the rubber spring is vulcanized in. This element already fulfills three of the four Points. The suspension takes place in the axial direction, the guide radial and the connection is guaranteed by vulcanization. Looking at the element in axial vertical position, there is a fastening point on the outer tube below and one on the inner tube at the top.

Die Erweiterung des Elements zur Gummi-Luftfeder geht folgendermaßen vor sich: Beide Rohre werden an der Unterseite luftdicht verschlossen, z.B. durch Einschweißen eines Bodens, jedoch so, daß zwischen dem Außenrohr einerseits und dem Gummikörper mit Innenrohr andererseits ein rundum dichter Hohlraum entsteht. Federt nun das Innenrohr bei Belastung nach unten, wird die im Hohlraum befindliche luft verdichtet und wirkt somit mittragend und federnd. Durch Regelung des Luftdruckes in dem Hohlraum über ein am Element angebrachtes Ventil kann die Tragfähigkeit der Feder den Erfordernissen angepaßt werden.The extension of the element to a rubber air spring goes as follows in front of you: Both pipes are hermetically sealed on the underside, e.g. by Welding in a bottom, but so that between the outer tube on the one hand and On the other hand, the rubber body with inner tube creates an all-round sealed cavity. If the inner tube springs down under load, the one in the cavity becomes air compresses and thus has a supporting and resilient effect. By regulating the air pressure in the cavity via a valve attached to the element, the load-bearing capacity of the Spring to be adapted to the requirements.

Als nächstes folt die Erweiterung des Gummi-Luftfederelements durch die Dämpfung, Die Punktion der Dämpfung: Der Verschlußboden des Innenrohres wird mit einem Drosselrückschlagventil versehen. Der Hohlraum des Federelements wird mit Flüssigkeit gefüllt, welche beim Einfedern des Innenrohres in dessen Innenraum über das Drosselventil verdrängt wird. Wird das Innenrohr an der Oberseite verschlossen, ergibt sich dadurch wieder das erwünschte Luftpolster. Dieses Luftpolster kann ebenfalls über ein Ventil regelbar ausgeführt werden.The next step is to expand the rubber air suspension element the attenuation, the puncture of the attenuation: the closure bottom of the inner tube is equipped with a one-way flow control valve. The cavity of the spring element is filled with liquid, which when the inner tube is compressed into whose Interior is displaced via the throttle valve. Will the inner tube at the top closed, this results in the desired air cushion again. This cushion of air can also be designed to be controllable via a valve.

Das Drosselrückschlagventil bewirkt, daß die Flüssigkeit beim Einfedern gebremst in das Innenrohr fließt, somit die Schwingung dämpft und beim Ausfedern die Flüssigkeit freizurückfliessen kann. Es besteht auch die Möglichkeit, mehrere Federelemente untereinander oder mit einem zentralen Steuergerät durch eine Luft- oder eine Flüssigkeitsleitung zu verbinden.The one-way flow control valve causes the fluid to compress during compression braked flows into the inner tube, thus damping the vibration and during rebound the liquid can flow back freely. There is also the option of several Spring elements with each other or with a central control unit through an air or to connect a liquid line.

Das Element kann bei jeweils entsprechender Gestaltung in jeder Lage eingebaut werden. Die Feder kann am vielseitigsten eingesetzt werden im Fahrzeugbau, aber auch in fast allen anderen Bereichen.The element can be in any position with the appropriate design to be built in. The spring can be used most versatile in vehicle construction, but also in almost all other areas.

Zusammengefaßt ergeben sich folgende vorteilhafte Punkte: - ein äußerst kompaktes und leichtes Federelement mit nur zwei Befestigungspunkten - eine exakte Abstimmbarkeit der Feder- und Dämpfwirkung - in den meisten Fällen keine zusätzliche Befestiung und Führung der abzufedernden Masse erforderlich - die Feder kann von weich bis hart reguliert werden, vorteilhaft z.B. bei Transportfahrzeugen von unbeladen bis beladen = Anheben oder Absenken der Feder durch verändern des luft- oder Flüssigkeitsdruckes - Eörperschalldämpfung, da keine Verbindung von Metall zu Metall - sehr günstige Herstellungskosten - verschleißfest, wartungsfrei und unempfindlich.In summary, the following advantageous points result: - an extremely compact and light spring element with only two attachment points - one exact one Adjustability of the spring and damping effect - in most cases no additional one Fastening and guidance of the mass to be cushioned required - the spring can be of can be regulated soft to hard, advantageous e.g. for transport vehicles from unloaded until loaded = raise or lower the spring by changing the air or liquid pressure - Structure-borne sound attenuation, as there is no metal-to-metal connection - very cheap Manufacturing costs - wear-resistant, maintenance-free and insensitive.

Ein in der Wirkungsweise ähnliches Federelement ist mir nicht bekannt.I am not aware of a spring element that is similar in its mode of operation.
