Abstract
Description
Die Erfindung betrifft ein Kolbenstangen-Zylinderaggregat gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a piston rod-cylinder unit according to the preamble of
Aus der
Damit über den Lufteinlass keine verschmutzte Luft in den Innenraum gelangt, ist dem Lufteinlass ein Filterelement vorgeschaltet. Dieses Filterelement ist in der Variante nach

Die
Die Aufgabe der vorliegenden Erfindung ist es, einen Kolbenstangenschutz dahingehend zu verbessern, so dass die aus dem Stand der Technik bekannten Nachteile behoben sind.The object of the present invention is to improve a piston rod protection to the effect that the disadvantages known from the prior art are eliminated.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst.According to the invention, the object is solved by the features of
Das Gehäuse bietet den Vorteil, dass es keine weitere Tragefunktion für ein weiteres Bauteil übernehmen muss. Folglich besteht eine deutlich erweiterte Konstruktionsfreiheit bei der Ausgestaltung des Filterelements. Dabei ist vorgesehen, dass mindestens ein Flächenbereich des Ringgehäuses als ein Filterelement ausgeführt ist. Der Flächenbereich besteht aus einer Netzgitterstruktur, die eine stabile Struktur aufweist.The housing has the advantage that it does not have to take on any additional carrying function for another component. Consequently, there is a significantly extended design freedom in the design of the filter element. It is provided that at least one area of the ring housing is designed as a filter element. The surface area consists of a grid structure, which has a stable structure.
Das Ringgehäuse umschließt das Ringlager. Ein Ringraum, den das Ringgehäuse zum Anschlusslager umschließt, stellt den Belüftungskanal dar.The ring housing encloses the ring bearing. An annular space, which encloses the ring housing to the terminal bearing, represents the ventilation channel.
In weiterer vorteilhafter Ausgestaltung weist das Ringgehäuse eine Aufnahmeöffnung für das zweite Ende des Kolbenstangenschutzes auf. Es besteht somit eine direkte Verbindung zwischen dem Ringgehäuse mit dem Filterelement und dem Innenraum im Kolbenstangenschutz.In a further advantageous embodiment, the annular housing has a receiving opening for the second end of the piston rod protection. There is thus a direct connection between the annular housing with the filter element and the interior in the piston rod protection.
Dabei kann vorgesehen sein, dass die Aufnahmeöffnung des Ringgehäuses das zweite Ende des Kolbenstangenschutzes formschlüssig hintergreift und damit eine Verliersicherung bildet.It can be provided that the receiving opening of the ring housing engages behind the second end of the piston rod protection positively and thus forms a captive.
Das Ringgehäuse ist durch seitliche Deckscheiben axial zum Ringlager fixiert. Bevorzugt stellen die seitlichen Deckscheiben den Flächenbereich, der als Filterelement ausgeführt ist. Dadurch muss der Luftstrom um 90° umgelenkt werden, ausgehend vom Filterelement über den Belüftungskanal zum Innenraum, so dass der Schmutzeintrag weiter minimiert wird.The ring housing is fixed by lateral cover plates axially to the ring bearing. Preferably, the side cover plates make the surface area, which is designed as a filter element. As a result, the air flow must be deflected by 90 °, starting from the filter element via the ventilation channel to the interior, so that the dirt entry is further minimized.
Bei einer Alternativausführung ist das Anschlussorgan als ein Stiftgelenk ausgeführt ist und das Stiftgelenk weist den Belüftungskanal auf und das Gehäuse mit dem Filterelement ist vorteilhafterweise als eine Kappe ausgeführt, die auf dem Stiftgelenkgehäuse aufsitzt.In an alternative embodiment, the connecting member is designed as a pin joint and the pin joint has the ventilation channel and the housing with the filter element is advantageously designed as a cap which rests on the pin joint housing.
Dabei ist vorgesehen, dass der Belüftungskanal in einem Stiftgelenkgehäuse ausgeführt ist.It is provided that the ventilation channel is designed in a pin joint housing.
Alternativ kann das Stiftgelenk mindestens einen Elastomerkörper aufweisen, in dem der Belüftungskanal eingeformt ist.Alternatively, the pin joint may have at least one elastomeric body in which the ventilation channel is formed.
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.
