Abstract
Description
Die Erfindung betrifft ein Dämpfventil entsprechend dem Oberbegriff von Patentanspruch 1.The The invention relates to a damping valve according to the preamble of claim 1.
Aus
der
Aufgabe der vorliegenden Erfindung ist es, die Dämpfkraftabweichungen bei einem Dämpfventil zu minimieren.task The present invention is the damping force deviations at a Damping valve too minimize.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, ein Kontaktbereich zwischen der Stützscheibe und der Fixierfläche als eine vom Grundkörper erhabene Fläche ausgeführt ist, deren radiale Ausdehnung kleiner ist als die Fixierfläche.According to the invention Task solved by a contact area between the support disk and the fixing surface as one from the main body raised surface accomplished is, whose radial extent is smaller than the fixing surface.
Der wesentliche Vorteil besteht darin, dass der Kraftflussweg ausgehend von der Ventilscheibe in die Stützscheibe und weiter auf die Fixierfläche wiederholgenau ausgeführt ist. Bei allen Teilen in der Verspannungskette gehen schon kleinste Maß- und Lagetoleranzen in den Kraftflussweg ein. Wenn man auch die radiale Lage des Kraftflusswegs bezogen auf alle verspannten Teile näher bestimmt, dann werden dadurch auch wirksame Hebellängen vorgegeben, die bei der Krafteinleitung auf die besagten Scheiben wirken und folglich auch die elastische Verformung beeinflussen.Of the significant advantage is that the power flow path starting from the valve disk into the support disk and on the fixing surface repeatable accomplished is. For all parts in the tension chain go even the smallest Dimensional and positional tolerances enter the force flow path. If you also consider the radial position of the force flow path Determined in terms of all strained parts closer, then be characterized also effective lever lengths given when the force on the said discs act and therefore also affect the elastic deformation.
In weiterer vorteilhafter Ausgestaltung ist die erhabene als eine Prägefläche ausgeführt. Ein Prägevorgang lässt sehr präzise Konturen entstehen. Es wird davon ausgegangen, dass der vollständige Kontaktbereich mit vertretbarem Aufwand nicht ausreichend hergestellt werden kann. Deshalb wird die radiale Ausdehnung und damit die Größe der erhabenen Fläche begrenzt, so dass nur ein partielles Prägen notwendig ist.In Further advantageous embodiment, the raised is designed as a stamping surface. One embossing process leaves a lot precise Contours arise. It is assumed that the full contact area can not be sufficiently produced with reasonable effort. Therefore, the radial extent and thus the size of the raised area limited, so that only a partial embossing is necessary.
Dabei wird angestrebt, dass die erhabene Fläche einen scharfkantigen Übergang zu ihrem Rand aufweist. Scharfkantig ist nicht unbedingt gleichzusetzen mit einem rechtwinkligen Übergang von der erhabene Fläche. In der Praxis hat sich ein konvexer Übergangsradius als tendenziell nachteiliger herausgestellt als beispielsweise ein konkaver Radius.there It is sought that the raised surface a sharp-edged transition to its edge. Sharp edged is not necessarily synonymous with a right-angled transition from the raised surface. In practice, a convex transition radius tends to be more disadvantageous than, for example, a concave radius.
Dabei ist vorgesehen, dass bevorzugt die erhabene Fläche auf der Stützscheibe ausgeführt ist. Die Stützscheibe wird vielfach an anderer Stelle schon vergleichsweise maßgenau hergestellt, so dass der Prägevorgang keinen erheblichen Kostenmehraufwand bedeutet.there is provided that preferably the raised surface on the support disk accomplished is. The support disk is often already produced comparatively accurate elsewhere, so that the embossing process means no significant cost overhead.
Alternativ kann die erhabene Fläche von dem die Fixierfläche aufweisendem Bauteil gebildet werden, die z. B. an einer Ausgleichsscheibe einer Kolbenstangenmutter angeprägt ist.alternative can the raised area from the fixing surface be formed component, the z. B. on a shim stamped on a piston rod nut is.
Bei einer Variante ist zwischen der Stützscheibe und der Fixierfläche eine separate Trennscheibe eingelegt, deren Außendurchmesser kleiner ist als die Fixierfläche.at a variant is between the support disk and the fixing surface a inserted separate cutting disc whose outer diameter is smaller as the fixation area.
Wenn man die Trennscheibe ausreichend dünn dimensioniert, dann treten randseitig keine nennenswerten Stanzgrate auf, so dass die Trennscheibe die erhabene Fläche bildet und an der Stützscheibe keine Prägung für den Kontaktbereich in Richtung der Fixierfläche vorgenommen werden muss.If you dimension the blade sufficiently thin, then step no noteworthy punching burrs on the edge, so that the cutting disc the raised surface forms and on the support disk no imprint for the Contact area in the direction of the fixing surface must be made.
