Description
Die Erfindung betrifft eine Mäanderfeder gemäß Oberbegriff des Anspruchs 1The invention relates to a meander spring according to the preamble of
Derartige Mäanderfedern sind aus dem Stand der Technik bei einer Vielzahl von Anwendungen bekannt. Als druckschriftlicher Stand der Technik sei auf
Weiter sind aus
Eine Mäanderfeder in ihrer einfachsten Form ist in
Mäanderfedern wie auch andere Federn aus dem Stand der Technik – beispielsweise Schraubenfedern – können unter Druckbelastung seitlich verkippen, insbesondere wenn die auf die Feder ausgeübte Kraft nicht streng entlang einer Wirklinie ausgeübt wird, welche sich von einem ersten zu einem zweiten Anordnungsmittel der Feder erstreckt.Meandering springs, as well as other prior art springs, such as coil springs, can tilt laterally under compressive loading, especially when the force applied to the spring is not strictly exerted along a line of action extending from a first to a second locating means of the spring.
Die damit einhergehenden Nachteile lassen sich am besten anhand eines Andruckkontaktes nachvollziehen, wie er beispielsweise in
Um dem Nachteil der instabilen Stauchung und des seitlichen Verkippens der Anordnungspunkte einer Mäanderfeder zu begegnen, müssen die Anordnungspunkte im Stand der Technik entsprechend dem gewünschten Bewegungsweg bei einer Federstauchung geführt werden. Im Falle der vorzitierten Druckschrift wird hierzu das Gehäuse in spezieller Weise ausgebildet.In order to counteract the disadvantage of the unstable compression and the lateral tilting of the arrangement points of a meandering spring, the arrangement points in the prior art must be guided in accordance with the desired movement path in a spring compression. In the case of the above-cited document, the housing is designed in a special way for this purpose.
Aufgabe der Erfindung ist es, eine Mäanderfeder zu schaffen, welche zumindest unter Druckspannung ein kontrolliertes Stauchungsverhalten aufweist. Insbesondere ist es Aufgabe der Erfindung, eine Mäanderfeder zu schaffen, bei welcher sich die Anordnungspunkte unter Druckspannung auf einer durch die Anordnungsmittel verlaufenden Geraden linear aufeinander zu bewegen.The object of the invention is to provide a meandering spring which has a controlled compression behavior at least under compressive stress. In particular, it is an object of the invention to provide a meandering spring in which the arrangement points move linearly towards each other under compressive stress on a straight line passing through the arrangement means.
Gelöst wird die Aufgabe von einer Mäanderfeder mit den Merkmalen des Anspruches 1.The problem is solved by a meander spring with the features of
Bei einer Aufführungsform vollzieht die Mäanderfeder unter Aufbau einer Federspannung eine rotative Bewegung um ihren Mittelpunkt.In a performance form, the meandering spring undergoes a rotational movement about its center, building up a spring tension.
Eine Ausführungsform kennzeichnet sich dadurch, dass die Federschenkel und der Kraftumlenkschenkel in einer gemeinsamen Ebene und die Federschenkel jeweils auf einer Seite einer durch die Anordnungsmittel der Mäanderfeder verlaufenden Geraden angeordnet sind.An embodiment is characterized in that the spring legs and the Kraftumlenkschenkel in a common plane and the spring legs are each arranged on one side of a line extending through the arrangement of the meandering spring straight line.
Bei dieser Ausführungsform ist es insbesondere von Vorteil, wenn die Mäanderfeder zu ihrem Mittelpunkt punktsymmetrisch aufgebaut ist, wobei die Mäanderfeder unter Aufbau einer Federspannung eine rotative Bewegung um ihren Mittelpunkt vollzieht und letztlich die Federschenkel wenigstens zwei mäanderartig nebeneinander angeordnete Federschenkelabschnitte aufweisen.In this embodiment, it is particularly advantageous if the meander spring is center-symmetrical to its center, wherein the meander performs a rotational movement about its center under construction of a spring tension and ultimately have the spring legs at least two meandering juxtaposed spring leg sections.
Diese Ausführungsform der erfindungsgemäßen Mäanderfeder bewirkt bei einer Stauchung eine Selbststabilisierung. Die beiden Anordnungsmittel bewegen sich linear aufeinander zu, auch wenn die von den Elementen auf die Mäanderfeder wirkende Kraftrichtung nicht entlang einer durch beide Anordnungsmittel verlaufenden Geraden verläuft. Über die Anzahl der Federschenkelabschnitte eines jeden Federschenkels lässt sich die Federcharakteristik besonders einfach beeinflussen.This embodiment of the meander spring according to the invention causes self-stabilization during compression. The two arrangement means move linearly toward one another, even if the direction of force acting on the meander spring by the elements does not run along a straight line passing through both arrangement means. On the number of spring leg sections of each spring leg, the spring characteristic can be particularly easily influenced.
Es ist weiterhin von Vorteil, wenn die Mäanderfeder beidseitig des Kraftumlenkschenkels eine identische Anzahl von Federschenkelabschnitten aufweist, was die Selbststabilisierung wesentlich verbessert.It is also advantageous if the meander spring on both sides of the Kraftumlenkschenkels having an identical number of spring leg sections, which significantly improves the self-stabilization.
Die Federschenkel bzw. die Federschenkelabschnitte der Federschenkel verlaufen bei einer bevorzugten Ausführungsform parallel zu einer durch die Anordnungsmittel der Mäanderfeder verlaufenden Geraden, weshalb bei dieser Ausführungsform vergleichsweise hohe Kräfte von der Mäanderfeder aufgenommen werden können.The spring legs and the spring leg portions of the spring legs extend in a preferred embodiment parallel to a straight line passing through the arrangement means of the meandering spring, which is why comparatively high forces can be absorbed by the meandering spring in this embodiment.
Eine ihren erforderlichen Einbauraum minimierende Ausführungsform der Mäanderfeder sieht vor, dass jede der Federwindungen jedes Federschenkels gekrümmt nach Art von C-Federn ausgebildet ist, wobei sich diese Ausführungsform fortbilden lässt, indem die Federschenkel jeweils eine in etwa halbkreisförmige Fläche überspannen und die Federschenkelabschnitte eines jeden Federschenkels nach Art von C-Federn gekrümmt und mäanderartig nebeneinander angeordnet sind, insbesondere wenn, die mittels des Kraftumlenkschenkels verbundenen Federschenkel eine im wesentlichen vollkreisförmige Fläche überspannen.An embodiment of the meandering spring which minimizes its required installation space provides that each of the spring turns of each spring leg is curved in the manner of C-springs, whereby this embodiment can be developed by the spring legs each covering an approximately semicircular surface and the spring leg portions of each spring leg curved in the manner of C-springs and arranged in a meandering manner next to each other, in particular when, by means of Kraftumlenkschenkels connected spring legs span a substantially fully circular area.
Bei einer solchen Mäanderfeder lassen sich aufgrund der bogenförmigen Verschachtelung der Federschenkelabschnitte ineinander auch sehr lange Federschenkel auf kleinstem Raum unterbringen.In such a meandering spring can be due to the arcuate nesting of the spring leg sections into each other also very long spring legs accommodate in a small space.
Letztlich kennzeichnet sich eine weitere Ausführungsform der erfindungsgemäßen Mäanderfeder dadurch, dass die Federschenkel gegensinnig mäandrierend ausgebildet sind.Finally, a further embodiment of the meander spring according to the invention is characterized in that the spring legs are formed in the opposite direction meandering.
Weitere Vorteile der Erfindung finden sich in der nachfolgenden Beschreibung bevorzugter Ausführungsformen. Es zeigen:Further advantages of the invention can be found in the following description of preferred embodiments. Show it:
