Description

Elastische Schutzbes2. LEEMZ. L~X2E2Liesweise für Kolbenstangen vo, n. StossdämL3fern." Die Neuerung bezieht sich auf eine elastische Schutzbespannung, vorzugsweise für Kolbenstangen von Stossdämpfern, und hat die Aufgabe zu vermeidnn, dass die Kolbenstange äusseren Einflüssen, Verschmutzungen od. dgl. ausgesetzt wird. Darüberhinaus kann die Schutzbespannung als Anschlag wirken. Elastic protective cover 2. LEEMZ. L ~ X2E2 Readily for piston rods in front of, after shock absorbers. " The innovation relates to an elastic protective covering, preferably for piston rods of shock absorbers, and has the task of avoiding that the piston rod is exposed to external influences, contamination or the like. In addition, the protective covering can act as a stop.

Neurungsgemäss besteht die Schutzbespannung aus einer über die Kolbenstange gezogenen, am Kolbenstangenauge und am Stossdämpfergehäuse befestigten Manschette aus sohaumgummiartigem Material mit geschlossenen Schwammkammern und gegebenenfalls durchgehender Aussenhaut, Dieses elastische Schutzmaterial hat den Vorteil, dass, weil die Schwammkammern geschlossen sind, keine Unreinigkeiten in das Schwamm-Material eindringen können, wobei die Schwammkammern und die gegebenenfalls durchgehende Aussenhaut auch weitgehend gegen Einflüsse von aussen abgesichert sind.According to the innovation, the protective covering consists of one over the piston rod pulled sleeve attached to the piston rod eye and to the shock absorber housing made of such a foam rubber-like material with closed sponge chambers and possibly continuous outer skin, this elastic protective material has the advantage that, because the sponge chambers are closed, no impurities in the sponge material can penetrate, the sponge chambers and the possibly continuous The outer skin is also largely protected against external influences.

Die Schutzbespannung wird zweokmässig durch in entsprechende Ringnute eingreifende Spannringbefestigungen gehalten, und zwar so, dass sie bei ausgezogener Kolbenstange unter Zugspannung und bei eingeschobener Kolbenstange unter Druckspannung steht. Neben der Verwendung als Schutzbespannung für die Kolbenstange von Stossdämpferkolben kann sie auch beispielsweise bei Federbeinaggregaten benutzt werden. Auspreislichen Gründen wird die elastische Schutzbespannung in ihrer ursprünglichen Lage so kurz gewählt, dass die zulässige Zugspannung restlos ausgenutzt werden kann.The protective covering is made in two dimensions by means of a corresponding ring groove engaging clamping ring fastenings held, in such a way that they are when extended Piston rod under tensile stress and, when the piston rod is pushed in, under compressive stress stands. In addition to being used as a protective covering for the piston rod of shock absorber pistons it can also be used, for example, for suspension strut assemblies. Pricing For reasons, the elastic protective covering is so short in its original position chosen so that the permissible tensile stress can be fully utilized.

Die Zeichnung zeigt eine beispielsweise Ausführungsform, und zwar Fig. 1 den unteren Teil eines Stossdämpfers mit ausgezogener Kolbenstange, Fig. 2 den zusammengeschobenen Dämpfer, bei dem die Schutzbespannung unter Druckspannung steht.The drawing shows an exemplary embodiment, namely Fig. 1 shows the lower part of a shock absorber with an extended piston rod, Fig. 2 the pushed together damper, in which the protective covering is under compressive stress stands.
