Abstract
Description
Die Erfindung betrifft einen Zuganschlag für einen Schwingungsdämpfer gemäß dem Oberbegriff von Patentanspruch 1.The The invention relates to a cable stop for a vibration damper according to the preamble of Claim 1.
Aus
der
Aufgabe der vorliegenden Erfindung ist es, einen Schwingungsdämpfer insbesondere nach dem Einrohrbauprinzip mit einem Zuganschlag zu realisieren, der einerseits keine Anschlaggeräusche verursacht, aber auch über die nötige Betriebsfestigkeit verfügt.task The present invention is a vibration damper in particular to realize with the single-pipe principle with a Zuganschlag, on the one hand no impact noises caused, but also about the necessary Operational stability features.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die erste Druckfeder als eine Schraubendruckfeder und die weitere Druckfeder als Tellerfeder ausgeführte ist, wobei die Federrate der Tellerfeder im größten Federwegbereich der Tellerfeder größer ist als die Federrate der Schraubendruckfeder.According to the invention Task solved by that the first compression spring as a helical compression spring and the other Compression spring is designed as a diaphragm spring, the spring rate the plate spring in the largest travel range the diaphragm spring is larger as the spring rate of the helical compression spring.
Die Kombination der beiden Feder bewirkt eine deutliche Geräuschreduzierung. Des weiteren kann diese Bauform eines Zuganschlags auch problemlos in einem Schwingungsdämpfer nach dem Einrohrbauprinzip verwendet werden, der aufgrund seiner Bauform häufig eine höhere Betriebstemperatur erreicht, bei der eine Feder aus einem Kunststoff nicht mehr dauerbetriebsfest ist.The Combination of the two springs causes a significant noise reduction. Furthermore, this design of a Zuganschlags also easily in a vibration damper be used according to the Einrohrbauprinzip, due to its Design frequently a higher one Operating temperature reached at which a spring made of a plastic is not more is permanently operational.
In weiterer vorteilhafter Ausgestaltung ist die Tellerfeder als geschlossene Ringscheibe ausgeführt. Das Ziel dieser Maßnahme bestet darin, dass das Dämpfmedium, dass sich oberhalb und unterhalb der Tellerfeder befindet, beim Einfedern des Zuganschlags verdrängt wird, wodurch eine zusätzliche hydraulische Dämpfkraft wirksam wird.In Another advantageous embodiment, the plate spring is closed Ring disc executed. The goal of this measure insists that the damping medium, that is located above and below the diaphragm spring, at Compression of the rebound stroke displaced will, creating an extra hydraulic damping force takes effect.
Gemäß einem Unteranspruch ist vorgesehen, dass die Tellerfeder an der ortsfesten Anschlagfläche, z. B. der Kolbenstangenführung, zur Anlage kommt. Es bietet sich die Möglichkeit, dass die erste als Schraubendruckfeder ausgeführte Zuganschlagfeder zum Beispiel über einen Federteller mit der Kolbenstange fest verbunden ist. Diese erste Feder verfügt über ein Mehrfaches der Masse im Vergleich zu der Tellerfeder. Deshalb kann die Tellerfeder axial schwimmend auf der Kolbenstange aufgefädelt sein, ohne dass kolbenstangenseitig eine permanente Fixierung der Tellerfeder vorliegt.According to one Under claim is provided that the plate spring to the stationary Stop surface z. B. the piston rod guide, comes to the plant. There is the possibility that the first as Executed helical compression spring Zuganschlagfeder for example over a spring plate is firmly connected to the piston rod. This first Spring has one Multiple of the mass compared to the plate spring. That's why the diaphragm spring be floating axially floating on the piston rod, without that piston rod side a permanent fixation of the plate spring is present.
In weiterer vorteilhafter Ausgestaltung kommen mehrere geschichtete Tellerfedern zur Anwendung, wobei die Tellerfedern jeweils mit ihrem Innen- und Außendurchmesser mit einer benachbarten Tellerfeder in Kontakt stehen, so dass zwischen den Tellerfedern ein mit Dämpfmedium gefüllter Ringraum vorliegt. Diese Anordnung der Tellerfedern vergrößern die hydraulische Dämpfkraft des Zuganschlags.In Another advantageous embodiment come several layered Disc springs for use, the disc springs each with their Inside and outside diameter to be in contact with an adjacent diaphragm spring so that between the disc springs with a damping medium filled Annular space is present. This arrangement of the disc springs increase the hydraulic damping force the Zuganschlags.
Bei der Auslegung der Tellerfeder sind widersprüchliche Anforderungen zu erfüllen. Eine kleine Federrate reduziert das Anschlaggeräusch, führt jedoch zu einem relativ großen Federweg und ggf. zu einer zu kleinen Gesamtfederrate des Zuganschlags. Deshalb ist der Federweg der mindestens einen Tellerfeder kleiner als der Federweg der Schraubendruckfeder.at The design of the diaphragm spring are contradictory requirements to meet. A small spring rate reduces the impact noise, but leads to a relative huge Travel and, if necessary, too small total spring rate of the cable stop. Therefore the spring travel of the at least one plate spring is smaller than that Spring travel of the helical compression spring.
