Description

Hydraulik-Kolben Es sind Hydraulik-Kolben aus Maschinenguß oder Stahl bekannt, die beidenends je eine Dichtungmanschette aufweisen, die ihrerseits z. B. aus Kunststoff gefertigt sind. Die Manschetten sind durch stirnseitige Ringe od. dgl. an dem Kolben befestigt. Hydraulic pistons These are hydraulic pistons made of machine cast or steel known, the two ends each have a sealing sleeve, which in turn z. B. are made of plastic. The cuffs are made of rings on the face or the like attached to the piston.

Diese und ähnliche Hydraulik-Kolben haben den Nachteil, daß ein Riefigwerden der Innenwandung des Zylinders unvermeidbar ist. Dieses Riefigwerden ist darauf zurückzuführen, daß die äußere Oberfläche des Kolbens unmittelbar mit der Innenwandung des Zylinders zusammen arbeitet.These and similar hydraulic pistons have the disadvantage that they become wrinkled the inner wall of the cylinder is unavoidable. This getting scared is on it attributed to the fact that the outer surface of the piston is directly connected to the inner wall of the cylinder works together.

Nach der Neuerung soll diese Riefenbildung vermieden werden, und die Neuerung besteht darin, daß zwischen = den beiden erwähnten Dichtungsmanschetten eine ring- förmige Buchse aus verschleißbarem Werkstoff besteht, der zumindest zum Teil aus synthetischem Kunststoff gebildet ist. Unter solchen Werkstoffen sind z. B.According to the innovation, this scoring should be avoided, and the innovation is that between = the two mentioned sealing collars an annular shaped bushing is made of wearable material, which is at least partially made of synthetic plastic. Among such materials are z. B.

Polyamide, wie sie z. B. unter den Namen Nylon und Perlon bekannt sind, oder mit letzteren behandelte natürliche Werkstoffe zu verstehen. Außerdem kommen auch Schichtpreßstoffe, Hartgewebe, Schweinshaut, Rohhaut od. dgl. in Frage.Polyamides, as they are e.g. B. known under the names nylon and perlon or natural materials treated with the latter. aside from that Laminates, hard tissue, pig skin, raw hide or the like are also possible.

Die ringförmige Buchse hat die Aufgabe, den Kolben zu führen. Sie gewährleistet, dass ohne Fremdstoffeinwirkung die Riefenbildung an der Innenwandung des Zylinders mit absoluter Sicherheit verhindert ist.The task of the ring-shaped bushing is to guide the piston. she ensures that the scoring on the inner wall is not affected by foreign matter of the cylinder is prevented with absolute certainty.

Auf der Zeichnung ist ein Ausführungsbeispiel der Neuerung schematisch dargestellt., Mit 1 ist der aus den beiden Hälften 1 und 2 bestehende Hydraulikkolbenkern, mit 3 der Hydraulikzylinder und mit 4 die Kolbenstange bezeichnet. In bekannter Weise sind beidenends des Kolbens 1, 2 je ein Ring 5 bzw. 6 vorgesehen, die zum Befestigen je einer Dichtungmanschette 7 bzw., 8 dienen.An exemplary embodiment of the innovation is shown schematically in the drawing shown., With 1 is the hydraulic piston core consisting of the two halves 1 and 2, with 3 the hydraulic cylinder and with 4 the piston rod. In well-known Way are both ends of the piston 1, 2 each a ring 5 and 6 are provided, which for Fasten one sealing sleeve 7 or 8, respectively.

Gemäß der Neuerung ist zwischen den beiden Manschetten 7,8 eine ringförmige Führungsbuchse 9 angeordnet, die zum Führen des Kolbens l, 2 dient und eine Riefenbildung an der Innenwandung des Zylinders 3 absolut verhindert.According to the innovation, there is an annular one between the two sleeves 7, 8 Guide bushing 9 is arranged, which is used to guide the piston 1, 2 and a scoring absolutely prevented on the inner wall of the cylinder 3.
