Description

Kolbenbefestigungen für Stoßdämpferkolben, die auf einer nach beiden Seiten verschiebbaren Kolbenstange sitzen, wurden bis heute meist in der Weise ausgeführt, daß die Kolbenstange einen Bund aufwies, gegen den der. Kolben mittels einer Ringmutter gespannt wurde. Diese Ausführung hat den Nachteil, daß die Kolbenstange erheblich im Durchmesser abgedreht werden muß, um den Bund zu bilden, und außerdem ein Gewinde auf die Kolbenstange geschnitten werden muß. Damit wird die Herstellung der Kolbenstange kostspielig.Piston mounts for shock absorber pistons that are on one after the other Sides sliding piston rods were usually carried out until today in such a way that the piston rod had a collar against which the. Piston by means of a ring nut was excited. This design has the disadvantage that the piston rod is considerably must be turned off in diameter to form the collar, and also a thread must be cut on the piston rod. This is the manufacture of the piston rod expensive.

Durch den Erfindungsgegenstand wird eine Kolbenstangenbefestigung geschaffen, die die Herstellung der Kolbenstange wesentlich vereinfacht. Die Kolbenstange ist in ihrer ganzen Länge von gleis chem Durchmesser und lediglich an der Stelle des Kolbensitzes mit einer oder mehreren Nuten versehen. In diese Nuten werden Halteringe eingelegt, die aus zwei Hklften bestehen und einen größeren Außendurchmesser als die Kolbenstange aufweisen. Die Halteringe werden von einer Flanschbüchse umschlosskn, die mit einem Bund versehen ist, der sich gigen die Halteringe legt. Die Büchse ist mit dem Kölben verschraubt. Hierdurch entsteht eine kraftschlüssige Verbindung des Kolbens oder der Kolbenstlange, die jederzeit wieder leicht gelöst werden kann.The subject matter of the invention provides a piston rod attachment created, which significantly simplifies the manufacture of the piston rod. The piston rod is of the same diameter over its entire length and only at the point the piston seat is provided with one or more grooves. Retaining rings are placed in these grooves inserted, which consist of two halves and a larger outer diameter than have the piston rod. The retaining rings are enclosed by a flange sleeve, which is provided with a covenant that lays down the retaining rings. The rifle is screwed to the piston. This creates a non-positive connection of the piston or the piston rod, which can be easily detached at any time.

In der Zeichnung ist eih Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Die Kolbenstange i ist mit zwei Nutten 2 versehen. In den Nuten liegen zweiteilige Halteringe 3, die von der Flanschbüchse 4 umschlossen werden. Die Flanschbüchse 4 ist mit einem Innenbund 5 versehen. Beim Anziehen der im Kolben 6 angebrachten Schrauben 7 wird der Kolben 6 gegen die Flanschbüchse 4 und damit gegen den Bund 5 gezogen. Die einander zugekehrten Flächen der Halteringe 3 werdien dhadurch.am .den Bund 8 der Kolbenstange gepreßt. Damit ist der Kolben auf der Kolbenstange festgespannt.The drawing shows an exemplary embodiment of the subject matter of the invention shown. The piston rod i is provided with two grooves 2. Lie in the grooves two-part retaining rings 3 which are enclosed by the flange bushing 4. The flange bushing 4 is provided with an inner collar 5. When tightening the attached in the piston 6 Screws 7, the piston 6 is against the flange bushing 4 and thus against the collar 5 drawn. The mutually facing surfaces of the retaining rings 3 are dh thereby.am .the collar 8 of the piston rod is pressed. The piston is now on the piston rod clamped.

PATENTANSPRÜCHE: i. Kolbenbefestigung, insbesondere für Stoßdämpferkolben, dadurch gekennzeichnet, daß in eine oder mehrere Nuten der Kolbenstange ein oder mehrere den Außendurchmesser der Kolbenstange überschreitende zweiteilige Halteringe eingelegt sind, an denen der Kolben axial festgelegt wird. PATENT CLAIMS: i. Piston fastening, in particular for shock absorber pistons, characterized in that one or more two-part retaining rings which exceed the outer diameter of the piston rod and to which the piston is axially fixed are inserted into one or more grooves in the piston rod. 2. Kolbenstangenbefestigung nach Anspruch i, dadurch gekennzeichnet, daß der Kolben an dem oder den in die Kolbenstange eingelegten zweiteiligen Halteringen durch den Innenbund einer über die Ringe geschobenen Flanschbüchse vermittels Schraubverbindung festgespannt wird. 2. Piston rod attachment according to claim i, characterized in that the piston on the one or the in the piston rod inserted two-part retaining rings through the inner collar of one pushed over the rings Flanged bushing is tightened by means of a screw connection. 3. Kolbenstangenbefestigung nach Anspruch i und 2, dadurch gekennzeichnet, daß der Kolben an zwei in die Kolbenstange eingelegten zweiteiligen Halteringen, die von einer Flanschbüchse mit einem Innenbund umschlossen sind, dadurch axial festgelegt wird, daß die zweiteiligen Halteringe gegen den zwischen den Ringnuten der Kolbenstange befindlichen Bund durch eine Schraubverbindung gepreßt werden.3. Piston rod attachment according to claim 1 and 2, characterized in that the piston is inserted into the piston rod at two inlaid two-part retaining rings, which are held by a flange bushing with an inner collar are enclosed, is axially determined by the fact that the two-part retaining rings against the collar located between the ring grooves of the piston rod by means of a screw connection be pressed.
