Abstract
Description
Die Erfindung bezieht sich auf ein Plattenventil eines hydraulischen Schwingungsdämpfers für einen Kolben, Bodenventil und/oder Zusatzventil, welches jeweils für die Zug- und Druckstufen Durchtrittskanäle aufweist, wobei die Austrittsmündungen mindestens der Zug- und/oder Druckstufe durch ringförmige, federbelastete Ventilscheiben abgedeckt sind.The invention relates to a Hydraulic damper plate valve for a piston, bottom valve and / or additional valve, each for the rebound and compression stages Passageways has, the outlet openings at least the rebound and / or compression stage through annular, spring-loaded valve disks are covered.
Es sind bereits Schwingungsdämpfer bekannt
(
Des weiteren sind Boden- und Zusatzventile bekannt, bei denen die Vorspannung durch die Lage der Nabe zu der Steuerkante am Grundventilkörper erzeugt wird. Hierbei ist für jede Vorspannungsvariante ein neuer Grundventilkörper notwendig. Zudem kann bei nicht kreisförmig angelegter Steuerkante keine gleich mäßige Flächenpressung erzielt werden. Die Dichtwirkung wird hiermit eingeschränkt.Furthermore, bottom and additional valves are known where the preload is due to the position of the hub to the control edge generated on the basic valve body becomes. Here is for Every preload variant requires a new basic valve body. It can also at not circular applied control edge no uniform surface pressure can be achieved. The This limits the sealing effect.
Hiervon ausgehend ist es Aufgabe der Erfindung, ein Federscheibenventil für einen Dämpfungskolben, ein Zusatzventil oder ein Bodenventil in einem Ein- oder Zweirohrschwingungsdämpfer zu schaffen, der nicht nur kostengünstig, sondern auch eine Variation der Dämpfungskraft durch eine Veränderung der Vorspannung der Federscheiben zulässt und zudem eine geringe Bauhöhe hat.Based on this, it is the task the invention, a spring washer valve for a damping piston, an additional valve or to create a bottom valve in a one or two pipe vibration damper, which is not only inexpensive, but also a variation of the damping force through a change allows the spring washers to be preloaded and also low height Has.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass mindestens eine Ventilscheibe mindestens zweiteilig ausgebildet ist, wobei ein Teil als Führungsfederscheibe ausgebildet ist, die von einer Distanzfederscheibe koaxial umgeben ist.This object is achieved according to the invention solved, that at least one valve disk is formed at least in two parts is, with a part as a guide spring washer is formed, which is coaxially surrounded by a spacer spring washer is.
Hierbei ist von Vorteil, dass durch Verwendung einer Distanzfederscheibe im koaxial äußeren Bereich des Federscheibenpaketes die Vorspannkraft über die Distanzfederscheibe eingeleitet wird, so dass eine gleichmäßige Flächenpressung an den Steuerkanten erzielt wird.The advantage here is that by Use of a spacer spring washer in the coaxial outer area of the spring washer package the preload over the spacer washer is introduced so that a uniform surface pressure is achieved at the control edges.
In Ausgestaltung der Erfindung ist vorgesehen, dass die Führungsfederscheibe und die Distanzfederscheibe unterschiedliche Materialdicken aufweisen. Durch die Dickendifferenz der Führungsfederscheibe gegenüber der Distanzfederscheibe lässt sich die Vorspannkraft des Ventils variieren.In an embodiment of the invention provided that the guide spring washer and the spacer spring washer have different material thicknesses. Due to the difference in thickness of the guide spring washer across from the spacer washer the preload force of the valve vary.
Nach einem weiteren wesentlichen Merkmal ist vorgesehen, dass zwischen den Austrittsmündungen und der Führungsfederscheibe mindestens eine weitere Ventilscheibe angeordnet ist. Auch bei dieser Ausführungsform ist von Vorteil, dass durch Verwendung von mindestens einer weiteren oder auch mehreren Ventilscheiben eine weitere Variation der Federkonstanten erreicht werden kann.After another essential Feature is provided that between the outlet mouths and the guide spring washer at least one further valve disk is arranged. Also in this embodiment is advantageous in that by using at least one more or even several valve disks a further variation of the spring constant can be achieved.
Nach einer weiteren Ausführungsforrn ist vorgesehen, dass auf der den Austrittsmündungen entgegengesetzten Seite der Führungsfederscheibe mindestens eine die Distanzfederscheibe abstützende Scheibe angeordnet ist. Diese weiteren abstützenden Scheiben sind im inneren Bereich eingespannt und bringen nicht nur eine gezielte Vorspannung auf das Federscheibenventil auf, sondern halten zusätzlich noch die Distanzfederscheibe in ihrer Position. Bei Verwendung von ein oder mehreren Scheiben lässt sich die Vorspannung entsprechend variieren.According to another embodiment it is envisaged that on the side opposite the outlet orifices the guide spring washer at least a washer supporting the spacer washer is arranged. This further supporting Discs are clamped in the inner area and not only bring a targeted preload on the spring-loaded valve, but hold in addition still the spacer spring washer in position. When using leaves one or more slices the preload will vary accordingly.
Eine einfache Fixierung des Federscheibenventils ist vorgesehen, indem alle Scheiben, ausgenommen der Distanzfederscheibe, in ihren radial inneren Bereichen eingespannt sind.A simple fixation of the spring-loaded valve It is provided that all washers, except the spacer washer, are clamped in their radially inner areas.
Bevorzugte Ausführungsbeispiele sind in den Zeichnungen dargestellt.Preferred embodiments are in the Drawings shown.
