Die Neuerung bezieht sich auf eine vorgespannte Radiallagerbuchse gemäß dem Oberbegriff des Anspruchs 1.The innovation relates to a preloaded radial bearing bush according to the preamble of claim 1.
Vorgespannte Lagerbüchsen mit integrierter Dämpfung sind in unterschiedlichen Aueführungen bekannt. So gibt es Radiallagerbuchsen (DE-PS 27 55 117, DE-PS 29 20 552), Axiallagerbuchsen (DE-PS 30 50 710) und Radial-Axial-Lager (EPS 00 80 910).Preloaded bearing bushes with integrated damping are known in different versions. There are radial bearing bushes (DE-PS 27 55 117, DE-PS 29 20 552), Axial bearing bushes (DE-PS 30 50 710) and radial-axial bearings (EPS 00 80 910).
On nun bei einer fiadiallagerbucb.se, die Gegenstand der Neuerung ist, in Querrichtung eine Dämpfung zu erzielen, die bis ca. 15 bis 25 Hz und 0,1 bis 0,5 mm Amplitude einen Verlustwinkel von 25 bis 4o° aufweist, wird in die vorgesehenen Kammern der Buchse eine Dämpfungsflüssigkeit eingefüllt. Die Schwierigkeit bei der Herstellung Jieser Buchse liegt im verdrängten Plüseigkeitsvolumen während des Kalibriervorganges, da hier evtl. die Guamipolster und Gummimetallteile bis zur Funktionsunfähijgkeit verformt werden können.On now at a fiadiallagerbucb.se, the subject of the The innovation is to achieve damping in the transverse direction that is up to approx. 15 to 25 Hz and 0.1 to 0.5 mm in amplitude has a loss angle of 25 to 40 °, a damping fluid is poured into the chambers provided in the bushing. The difficulty in making it This socket is in the displaced fluid volume during the calibration process, since the guami cushions and rubber-metal parts can be deformed to the point of being unable to function.
Aufgabe der Neuerung ist es daher, die Kalibrierhülse so zu entwickeln, daß das soeben erwähnte Problem nicht mehr auftritt.The task of the innovation is therefore to develop the calibration sleeve in such a way that the problem just mentioned no longer occurs occurs.
Die Lösung der Aufgabe besteht neuerurgsgemäß darin, daß die drehbare Kalibrierhülse, die nach dem Einpressen der Innenbuchse beidseitig umgebördelt ibt., zwei gegenüberliegende Bohrungen aufweist, die während des Einfüllens der Dämpfungsflüssigkeit über den Ringkammern angeordnet sind, die aber nach Beendigung der Füllung verschlossen über dem Gummipolster liegen.The solution to the problem is, according to the present day, that the rotatable calibration sleeve, which is flanged on both sides after the inner sleeve has been pressed in., has two opposing bores, which during filling the damping fluid arranged over the annular chambers which, however, are closed over the rubber cushion after the filling is complete.

Weitere zweckmäßige Ausgestaltungen der Neuerung sind in den Unteransprüchen genannt.Further expedient refinements of the innovation are mentioned in the subclaims.
Anhand schemetischer Zeichnungen sind Aufbau und Wirkungsweise der Neuerung beispielsweise beschrieben. Dabei zeigtThe structure and mode of operation are based on schematic drawings of the innovation, for example. It shows

Fig. 3 die Buchse im gebrauchsfähigen Zustand.Fig. 3 shows the socket in a usable state.
Nach Fig. la und Ib besteht die Buchse 1 aus einem metallischen Innenteil 2, einem Gummikörper 3 und den ungefüllten Ringkammern 4 und 5» die über einen umlauffenden Drosselspalt 6 miteinander in Verbindung stehen.According to Fig. La and Ib, the socket 1 consists of a metallic inner part 2, a rubber body 3 and the unfilled annular chambers 4 and 5 »which have a circumferential Throttle gap 6 are in communication with one another.
Fig. 2 zeigt die Buchse mit der drehbaren Kalibrierdüse 7« die nach dem Einpressen der Xnnenbuchse beidseitig umgebördelt ist, damit beim Kalibrieren die Innenbuchse nicht nach außen gedrängt wird. Die Ringkammern 4 und 5 sind noch ungefüllt. Die Buchse wird also trocken kalibriert, wobei die Buchse unter Vorspannung gesetzt wird. Danach wird die Ringkammer 4 über die untere Bohrung 8 der Kalibrierhülse 7 mit Hilfe einer Düse mit einer Dämpfungsflüssigkeit (Viskosität 10 bis 100.000 cps.) befüllt. Nachdem die Ringkammer 4 gefüllt ist, steigt die Flüssigkeit über den Drosselspalt 6 in die RLngkammer 5. Die verdrängte Luft entweicht dabei durch die Bohrung 9 nach außen.Fig. 2 shows the socket with the rotatable calibration nozzle 7 « which is flanged on both sides after the inner bushing has been pressed in, so that the inner bushing does not appear during calibration is pushed outwards. The annular chambers 4 and 5 are still unfilled. The socket is calibrated dry, whereby the bushing is placed under tension. Then the annular chamber 4 via the lower bore 8 of the Calibration sleeve 7 with the aid of a nozzle with a damping liquid (Viscosity 10 to 100,000 cps.) Filled. After the annular chamber 4 is filled, the liquid rises Via the throttle gap 6 into the longitudinal chamber 5. The displaced air escapes through the bore 9 outward.
