Abstract
Description
Die Erfindung betrifft einen Schwingungsdämpfer mit amplitudenselektiver Dämpfkraft gemäß dem Oberbegriff von Patentanspruch 1.The The invention relates to a vibration damper with amplitude-selective damping force according to the generic term of claim 1.

Die ältere
Für einen Absatz, der als ebene Stützfläche der Trennscheibe dienen soll, ist eine spanende Bearbeitung unerlässlich, da ansonsten ein Schiefstand oder eine Leckstelle nicht ausgeschlossen werden kann. Entsprechend teuer ist die Herstellung des Gehäuses.For one Paragraph, as a flat support surface of the Cutting disc, a machining is essential, otherwise an obliquity or a leak is not excluded can be. Accordingly expensive is the production of the housing.
Bei einer radialen Versickung muss gewährleistet sein, dass über die gesamte Laufzeit des Schwingungsdämpfers eine Verstopfung der mindestens einen Durchlassöffnung vermieden wird, auch dann, wenn sich die Trennscheibe z. B. durch Materialsetzungen an der Trennscheibe oder der Versickung lösen sollte.at a radial infiltration must be ensured that over the entire duration of the vibration damper a blockage of the at least one passage opening is avoided, even if the blade z. B. by Material should dissolve on the cutting disc or the seepage.
Aufgabe der vorliegenden Erfindung ist es eine Fixierung der Trennscheibe zu realisieren, die einerseits einfach und kostengünstig herstellbar ist. Eine weitere Teilaufgabe besteht darin, dass die Durchlassöffnungen über die gesamte Laufzeit des Schwingungsdämpfers stets offen bleiben sollen.task The present invention is a fixation of the cutting wheel to realize, on the one hand easy and inexpensive to produce is. Another subtask is that the passage openings on the the entire duration of the vibration always remain open should.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Trennscheibe durch eine radiale Versickung im Gehäuse formschlüssig verdrehfest fixiert ist, wobei in einer Mantelfläche der Trennscheibe für die Versickung eine angepasste Anzahl von Taschen ausgeführt ist. Die Taschen lassen, wenn überhaupt, nur eine begrenzte Verdrehung der Trennscheibe zu. Die Versickung kann jedoch keinesfalls in Überdeckung mit den Durchlassöffnungen der Trennscheibe gelangen.According to the invention Task solved by that the cutting disc rotationally positive fit by a radial Einfickung in the housing is fixed, wherein in a lateral surface of the cutting disk for the Aufickung an adapted number of pockets is executed. Leave the bags, if anything, only a limited rotation of the blade to. The trickle can but by no means in surplus with the passage openings get the cutting disc.
Der große Vorteil besteht darin, dass selbst dann, wenn sich die Trennscheibe axial lockern sollte, keine Verdrehung der Trennscheibe auftreten kann, die zu einem Verschluss der Durchlassöffnung führen könnte.Of the size The advantage is that even if the cutting disc should loosen axially, no rotation of the cutting disc can occur which could lead to a closure of the passage opening.
Mit dem Ziel, eine besonders einfache Fertigung der Trennscheibe zu erreichen, sind die Taschen axial in Richtung des Trennkolbens offen ausgeführt sind. Folglich kann die Trennscheibe sehr einfach in einem Sinterverfahren hergestellt werden.With the goal of a particularly simple production of the cutting disc reach, the pockets are open axially in the direction of the separating piston accomplished are. Consequently, the cutting wheel can be very easily sintered getting produced.
Die Teilaufgabe der einfachen Fixierung der Trennscheibe, die von einer Stützfläche eines Bodens im Gehäuse abgestützt wird, wird dadurch gelöst, dass die Stützfläche eine konische Kontur aufweist.The Partial task of simple fixation of the cutting disc, by a Support surface of a Floor in the housing supported will be solved by that the support surface a has conical contour.
Eine konische Kontur garantiert eine horizontale Ausrichtung der Trennscheibe.A conical contour guarantees a horizontal alignment of the cutting disc.
Dieser Selbstausrichteffekt kann dadurch gesteigert werden, indem die Trennscheibe in Richtung des Bodens zumindest im Kontaktbereich eine ballig geformte Kontaktfläche aufweist.This Self-aligning effect can be increased by the cutting disc towards the bottom at least in the contact area a spherically shaped contact area having.
Der Boden des Gehäuses wird durch ein spanloses Umformverfahren hergestellt, so dass eine bisher notwendig spanende Bearbeitung entfallen kann, wodurch ein erheblicher Kostenvorteil erreicht wird.Of the Bottom of the case is manufactured by a chipless forming process, so that a previously necessary machining can be omitted, creating a significant cost advantage is achieved.
Um eventuelle Bearbeitungsgrate oder Form- und/oder Lageabweichungen des Bodens kompensieren zu können, wird der Übergang zwischen einer Mantelfläche der Trennscheibe und der Kontaktfläche von einem Absatz gebildet.Around possible machining burrs or shape and / or position deviations to compensate for the soil, becomes the transition between a lateral surface the cutting disc and the contact surface formed by a paragraph.
Eine weitere Maßnahme für eine einfache Herstellung der Trennscheibe besteht darin, dass die Kontaktfläche von mehreren Stützfüßen gebildet wird, zwischen denen die mindestens eine Durchlassöffnungen ausgeführt ist.A further consequences for one simple preparation of the cutting wheel is that the contact surface of several support feet is formed, between which the at least one passage openings is executed.
