Description
Gummizugfeder, insbesondere für Kraftfahrzeuge Bei Gummifedern für Kraftfahrzeuge ist es bekannt, 'Gummistreifen oder Gummiösen verschiedener Länge zu benutzen, die derartig zu dem abzufedernden Teil eingestellt sind, daß die einzelnen Teile der Gummifedern fortschreitend nacheinander zur Wirkung kommen.Elastic tension spring, especially for motor vehicles In the case of rubber springs for Motor vehicles are known to have 'rubber strips or rubber eyelets of various lengths to use, which are adjusted to the part to be cushioned that the individual Parts of the rubber springs gradually come into effect one after the other.
Bei derartigen Ausführungen, bei denen also die ösenförmigen Gummiringe verschiedene Angriffslänge besitzen, besteht der Nachteil, daß nicht - nur ein ruckweiser Einsatz der verschiedenen Federbeile nacheinander erfolgt, sondern daß :auch eine sehr sperrige Bauart der. Abfederung entsteht, da ja -die: verschiedene Länge besitzenden Gummifedern nebeneinanderliegen und :auch besonders ,an den Federhalterungen angeschlossen sein müssen.In such designs, where the eyelet-shaped rubber rings have different attack lengths, there is the disadvantage that not - only a jerk Use of the different feather axes takes place one after the other, but that: also one very bulky design of the. Cushioning arises, because yes -the: possessing different lengths Rubber springs are next to each other and: also especially, connected to the spring holders must be.
Andererseits ist es bekannt, mit steigender Spannung ;gewickelte Gummifedern mit der Wirkung anzuwenden, daß zunächst die eine höhere Spannung besitzenden, .außenliegenden Teile und fortschreitend danach die inneren Teile beansprucht werden. Dabei werden ;aber die unterhalb der Angriffspunkte liegenden Gummilagen von Anfang :an - zusammengedrückt. Solche Federn werden also nicht nur auf Zug, sondern :auch :auf Druck beansprucht.On the other hand, it is known, with increasing tension; coiled rubber springs to apply with the effect that first of all the higher tension Parts and progressively thereafter the inner parts are stressed. Be there ; but the rubber layers below the points of application from the beginning: - pressed together. Such springs are not only subjected to tension, but also: to compression.
Schließlich ist es bekannt, mehrere nebeneinanderliegende Gummistreifen ganz oder teilweise aneinanderzuvulkanisieren. Auch wurde vorgeschlagen, bei nur auf Druck beanspruchten Gummiblöcken Gummilagen verschiedener Härte aufeinanderzulegen, wobei die Gummilagen desto härter gestaltet sind, je näher sie den starren Platten benachbart sind. Ein derartiger Gummiblock wird also bei der Belastung immer härter.Finally, it is known to have several adjacent rubber strips fully or partially vulcanized to one another. It was also suggested at only Laying rubber blocks of different hardness on top of each other under pressure, whereby the rubber layers are made harder the closer they are to the rigid plates are adjacent. Such a rubber block becomes harder and harder with the load.
Demgegenüber besteht die vorliegende Erfindung darin, daß die nebeneinanderliegenden Gummilagen bzw. -streifen der Gummifeder gleiche Länge aufweisen, an ihren Enden miteinander verbunden sind und in der Zugrichtung verschiedene Vorspannung besitzen, wobei der zunächst beanspruchte mittlere Gummistrang die größte Vorspannung, die danebenliegenden benachbarten Gummistreifen jeweilig progressiv weniger Vorspannun,g besitzen.In contrast, the present invention is that the adjacent Rubber layers or strips of the rubber spring have the same length at their ends are connected to each other and have different pretension in the pulling direction, where the initially stressed middle rubber strand has the greatest pre-tension, the adjacent rubber strips progressively less preload, g own.
Durch die Erfindung wird eine Gummiifeder ,geschaffen, bei der die verschiedenen Federstreifen fortschreitend allmählich zur Wirkung kommen, ohne daß, irgendein ruckweiser Einsatz der Federn erfol;gt. Dabei werden die Gummistreifen nur auf Zwg beansprucht. Die Herstellung solcher Federn ist einfach, sie können auch in verhältnismäßig ,gedrängter Bauart hergestellt werden.By the invention, a rubber spring is created in which the different spring strips gradually come into effect without, any jerky use of the springs occurs. This is where the rubber strips are only claimed on Zwg. Making such springs is easy, you can can also be produced in a relatively compact design.
Die Gummifeder ;gemäß. der Erfindung hat ferner den-Vorteil, daß verhältnismäßig kurze: Federwege vorhanden sind, daß man eine, einheitliche Feder erhält, bei der die Teile miteinander verbunden sind und daß doch eine progressive Steigerung der Abfederung erzielt wird.The rubber spring; according to. the invention also has the advantage that relatively short: spring travel is available so that a uniform spring is obtained in which the parts are connected with each other and that a progressive one Increase in cushioning is achieved.
Ein weiteres Erfindungsmerkmal besteht darin, daß die verschiedene Vorspannung besitzenden nebeneinanderliegenden, an den Enden verbundenen Gummistreifen in an sich bekannter Weise ganz oder teilweise aneinandervulkanisiert sind.Another feature of the invention is that the various Pre-tensioned rubber strips lying next to one another and connected at the ends are wholly or partially vulcanized to one another in a manner known per se.
Die Erfindung läßt sich in verschiedener Weise ausführen. Sie ist in der Zeichnung in einigen Ausführungsbeispielen veranschaulicht, und zwar zeigt Abb. i rein schematisch das Federsystem gemäß der Erfindung, Abb. 2 eine andere Ausführungsform des Federsystems in schematischer Darstellung, Abb.3 einen Schnitt durch eine Gummifeder nach der Erfindung und Abb. 4. eine andere Ausführungsform der Gummifeder im Schnitt.The invention can be carried out in various ways. she is illustrated in the drawing in some exemplary embodiments, namely shows Fig. I purely schematically the spring system according to the invention, Fig. 2 another Embodiment of the spring system in a schematic representation, Figure 3 a section by a rubber spring according to the invention and Fig. 4. Another embodiment the rubber spring in section.
Wie aus der Abb. i ersichtlich ist, besteht die Gummifeder aus mehreren nebeneinanderliegenden Streifen a, b, c, d. Erfindungsgemäß ist der Hauptstreifen a mit der größten Vorspannung in der Zugrichtung versehen. Die dann seitlich angebrachten Federstreifen b, c, d besitzen jeweilig eine geringer; Vorspannung, ,also b weniger als a, c weniger als b und d weniger ,als e.As can be seen from Fig. I, the rubber spring consists of several adjacent strips a, b, c, d. According to the invention, the main strip a is provided with the greatest prestress in the pulling direction. The laterally attached spring strips b, c, d each have a smaller one; Preload, i.e. b less than a, c less than b and d less than e.
In Abb.2 wird von zwei mittleren, die ,größte Vorspannung besitzenden Streifen a ausgegangen, an die sich beiderseits jeweilig weniger Vorspannung besitzende Streifen b und darüber noch ;geringere Vorspannung besitzende Streifen c anschließen.In Fig.2 there are two middle ones that have the greatest prestress Strip a assumed that each side has less bias Strips b and above; connect stripes c with a lower tension.
In Abb.3 ist gezeigt, daß, ,ausgehend von dem mittleren Hauptspannungs-, also die grölte Vorspannung besitzenden Streifen a, die sich daran .anschließenden, danebenliegenden, jeweilig geringere Vorspannung besitzenden Streifen b, c, d nur an der Ober- und Unterkante durch Vulkanisation e, f miteinander verbunden sind.In Fig.3 it is shown that, starting from the mean principal stress, that is, the stripes a, which have the greatest prestress, and the adjacent ones, adjacent strips b, c, d only have lower bias are connected to one another at the upper and lower edges by vulcanization e, f.
In Abb. ¢ ist ,gezeigt, daß die Gummistreifen vollkommen über ihre ;ganze Länge bei ä aneinandervulkanisiert sind. Auch ist hierbei ,gezeigt, daß die einen gemeinsamen Gummiblock bildenden Gummistreifen sowohl am oberen ,als .auch unteren Ende durch die abzufedernden Teile ht, z miteinander verbunden sind.In Fig. ¢ it is shown that the rubber strips are completely over their ; full length at ä are vulcanized together. It is also shown here that the a rubber strip forming a common rubber block both on the upper and also lower end by the parts to be cushioned ht, z are connected to one another.
