Abstract
Description
Die Erfindung betrifft einen Schwingungsdämpfer mit einem Tilger gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a vibration damper with a Tilger according to the preamble of
Aus der
Die
Eine zweite Ausführungsform zeichnet sich dadurch aus, dass die Tilgermasse innerhalb des Schwingungsdämpfers angeordnet ist und sich beispielsweise an einem Boden des Schwingungsdämpfers federnd abstützt.A second embodiment is characterized in that the absorber mass is arranged within the vibration damper and is resiliently supported, for example, on a bottom of the vibration damper.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine weitere Lösung für einen Schwingungsdämpfer mit einem Tilger zu finden.The object of the present invention is to find another solution for a vibration damper with a absorber.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, die nachgiebige Lagerung zwei beabstandete Anschläge aufweist, zwischen denen sich die Tilgermasse bewegen kann, wobei zwischen der Tilgermasse und der Kolbenstange eine definierte Reibkraft wirksam ist.According to the invention, the object is achieved, the resilient bearing having two spaced stops, between which the absorber mass can move, wherein between the absorber mass and the piston rod a defined friction force is effective.
Der Vorteil der Erfindung besteht darin, dass man für die Bedämpfung der Schwingbewegung der Tilgermasse keine zusätzlichen Elastomerkörper oder sonstige Federungen benötigt. Die Gesamtkonstruktion des Tilgers vereinfacht sich und der radiale Bauraum kann besser ausgenutzt werden.The advantage of the invention is that you need for the damping of the oscillatory motion of the absorber mass no additional elastomer body or other suspensions. The overall design of the absorber is simplified and the radial space can be better utilized.
In weiterer vorteilhafter Ausgestaltung ist die Tilgermasse ringförmig ausgeführt.In a further advantageous embodiment, the absorber mass is designed annular.
Bei einer möglichen Ausführungsform ist die Tilgermasse außerhalb des Zylinders angeordnet und mit einem Schutzrohr für die Kolbenstange verbunden. Die Masse des Schutzrohres wirkt ebenfalls als Tilger, so dass der Zusatzaufwand für den Tilger vergleichsweise gering ist.In one possible embodiment, the absorber mass is arranged outside the cylinder and connected to a protective tube for the piston rod. The mass of the protective tube also acts as a absorber, so that the additional expense for the absorber is comparatively low.
Um Anschlaggeräusche zu vermeiden, sind die Anschläge elastisch ausgeführt. Zur Versteifung der Anschläge kann rückseitig eine starre Scheibe verwendet werden.In order to avoid impact noises, the stops are made elastic. To stiffen the attacks can be used on the back of a rigid disc.
Um den Tilger mit einer standardisierten Bauform verschiedenen Anwendungen anpassen zu können, ist die Reibkraft zwischen der Tilgermasse und der Kolbenstange einstellbar.In order to be able to adapt the absorber with a standardized design to different applications, the frictional force between the absorber mass and the piston rod can be adjusted.
Dafür weist die ringförmige Tilgermasse einen Schlitz auf, über dessen Schlitzbreite die Reibkraft einstellbar ist.For this purpose, the annular absorber mass has a slot over the slot width of which the frictional force can be adjusted.
Es besteht zudem die Möglichkeit, dass die Schlitzbreite über einen Aktuator einstellbar ist. Der Aktuator kann an einen Regelkreis angeschlossen sein, so dass der Tilger gezielt einsetzbar ist.There is also the possibility that the slot width is adjustable via an actuator. The actuator may be connected to a control loop, so that the absorber can be used selectively.
Aufgrund der nur kleinen Schlitzbreitenänderungen zur Verstellung der Reibkraft ist vorteilhafterweise vorgesehen, dass der Aktuator von mindestens einem Piezoelement gebildet wird.Due to the small slot width changes for adjusting the friction force is advantageously provided that the actuator is formed by at least one piezoelectric element.
Anhand der folgenden Figurenbeschreibung soll die Erfindung näher erläutert werden.The invention will be explained in more detail with reference to the following description of the figures.
