Abstract
Description
Die Erfindung betrifft ein Federsystem nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a spring system according to the preamble of the claim 1.
In
der
Aufgabe der Erfindung ist es, ein Federsystem mit einer Federcharakteristik mit steilem Abfall der Kraft-Weg-Kennlinie anzugeben, das einfach hergestellt werden kann.task The invention is a spring system with a spring characteristic with steep drop in the force-displacement curve To specify that can be easily made.
Die Erfindung löst diese Aufgabe durch Bereitstellung eines Federsystems mit den Merkmalen des Patentanspruchs 1.The Invention solves This object is achieved by providing a spring system with the features of Patent claim 1.
Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous embodiments and further developments of the invention are specified in the dependent claims.
Erfindungsgemäß umfasst ein Federsystem mindestens eine erste Feder, die eine lineare Federcharakteristik aufweist und mindestens eine zweite Feder, die eine nichtlineare Federcharakteristik aufweist und mit der ersten Feder verbunden ist, so dass eine zugehörige Kraft-Weg-Kennlinie das Federsystems einen Bereich mit einem steilen Abfall aufweist.According to the invention a spring system at least a first spring having a linear spring characteristic and at least one second spring having a non-linear spring characteristic and is connected to the first spring, so that an associated force-displacement characteristic the spring system has an area with a steep drop.
Die erfindungsgemäße Verbindung der ersten mit der zweiten Feder ermöglicht die Bildung eines Federsystems mit einer stabilen Mittenlage sowie zwei stabilen Endpositionen, das beispielsweise zur Speicherung der kinetischen Energie im Zusammenhang mit einer Aktorbewegung oder dem leistungslosen Halten einer Endpositionen verwendet werden kann.The inventive compound the first with the second spring allows the formation of a spring system with a stable center position and two stable end positions, for example, related to the storage of kinetic energy with an actuator movement or the powerless holding of an end position can be used.
In Ausgestaltung des erfindungsgemäßen Federsystems ist der Grad der Steilheit des Abfalls der Kraft-Weg-Kennlinie durch Verändern der Federkonstanten der ersten Feder veränderbar.In Embodiment of the spring system according to the invention is the degree of steepness of the drop in the force-displacement curve Change the spring constant of the first spring changeable.
Der Bereich kann beispielsweise eine negativ-differentielle Kraft-Weg-Kennlinie aufweisen. Zwar können Tellerfedern ebenfalls eine negativ-differentielle Kraft-Weg-Kennlinie aufweisen, deren Durchmesser nehmen allerdings mit wachsendem Federweg überproportional zu, so dass ein größerer Bauraum benötigt wird.Of the Range may, for example, a negative-differential force-displacement curve exhibit. Although you can Disc springs also a negative-differential force-displacement curve However, their diameter take disproportionately with increasing travel to, so that a larger space needed becomes.
In weiterer Ausgestaltung ist das erfindungsgemäße Federsystem als kreuzförmiges Stanzteil hergestellt, das nach dem Stanzen gebogen und wärmebehandelt wird.In In another embodiment, the spring system according to the invention is produced as a cross-shaped stamped part, which is bent and heat-treated after punching.
Dadurch wird eine kostengünstige Herstellung eines Federsystems mit negativ-differentieller Kraft-Weg-Kennlinie, ermöglicht, die auf einer geschickten Kombination einer nach linearem Kraft-Weg-Gesetz wirkenden Freiformfläche mit einer nach nichtlinearem Kraft-Weg-Gesetz wirkenden Freiformfläche beruht.Thereby will be a cost effective Production of a spring system with negative-differential force-displacement characteristic, allows those on a skillful combination of a linear force-displacement law acting freeform surface is based on a non-linear force-displacement law acting freeform surface.
In weiterer Ausgestaltung des erfindungsgemäßen Federsystems weist ein oberer Teil des gebogenen Stanzteils die lineare Federcharakteristik und ein unterer Teil des gebogenen Stanzteils die nichtlineare Federcharakteristik auf.In further embodiment of the spring system according to the invention has a upper part of the bent punched part, the linear spring characteristic and a lower part of the bent punching part the nonlinear spring characteristic on.
In weiterer Ausgestaltung umfasst ein erfindungsgemäßes Federsystem eine erstes Teilfedersystem aus einer ersten und einer zweiten Feder, das mit einem zweiten Teilfedersystem aus einer ersten und zweiten Feder verbunden ist, so dass das Federsystem eine stabile Mittellage und zwei stabile Endpositionen aufweist.In In another embodiment, a spring system according to the invention comprises a first Part spring system of a first and a second spring, with a second part spring system of a first and second spring is connected, so that the spring system a stable middle position and has two stable end positions.
Das erfindungsgemäße Federsystem kann beispielsweise in einem Ventil mit selbsthaltenden Endpositionen eingesetzt werden.The Inventive spring system For example, in a valve with self-holding end positions be used.
Eine vorteilhafte Ausführungsform der Erfindung ist in den Zeichnungen dargestellt und wird nachfolgend beschrieben.A advantageous embodiment The invention is illustrated in the drawings and will become apparent below described.
Dabei zeigen:there demonstrate:
Durch das erfindungsgemäße Federsystem aus einer seriellen Anordnung einer linearen und einer nichtlinearen Feder wird eine kostengünstige Herstellung eines Federsystems ermöglicht, dessen Kraft-Weg-Kennlinie einen Bereich mit einem steilen Abfall aufweist. Die Kombination dieser beiden Federn ermöglicht die Bildung eines Systems mit einer stabilen Mittenlage sowie mit zwei stabilen Endpositionen, das beispielsweise zur Speicherung der kinetischen Energie im Zusammenhang mit einer Aktorbewegung oder dem leistungslosen Halten einer Endpositionen verwendet werden kann.By the spring system of the invention a serial arrangement of a linear and a nonlinear Spring will be a cost-effective production a spring system allows its force-displacement curve is an area with a steep drop having. The combination of these two springs allows the Formation of a system with a stable center position and with two stable end positions, for example, to store the kinetic Energy related to an actuator movement or the powerless Holding an end position can be used.
