Ring für eine schwingungsdämpfende Gelenkkupplung für AuspuffSchalldämpfer von Kraftfahrzeugen Ring for a vibration-damping articulated coupling for exhaust silencers from motor vehicles
Die Erfindung betrifft einen Ring für eine schwingungsdSmpfende Gelenkkupplung für Auspuffschalldämpfer von Kraftfahrzeugen. The invention relates to a ring for a vibration damping device Articulated coupling for exhaust silencers from motor vehicles.
Es ist Zweck der Erfindung, einen Ring dieser Gattung zu schaffen, dessen Konstruktion einfach und ökonomisch ist und der die von dem Fahrzeugmotor zu dem Auspuffschallschalldämpfer übertragenen Vibrationen wirksam zu dämpfen vermag.It is the purpose of the invention to create a ring of this type, the construction of which is simple and economical and that transmitted from the vehicle engine to the exhaust muffler Able to dampen vibrations effectively.
Hierzu ist der Ring erfindungsgemäß dadurch gekennzeichnet, daß er aus einem einstückigen mittels Sinterung von mit Graphitpulver gemischtem Metallpulver hergestellten Körper besteht,der eine zylindrische Innenfläche aufweist und eine Außenfläche besitzt, die im wesentlichen einem Teil einer Kugelfläche entspricht. For this purpose, the ring is characterized according to the invention that it consists of a one-piece body produced by sintering metal powder mixed with graphite powder, the has a cylindrical inner surface and has an outer surface which corresponds substantially to part of a spherical surface.
Gemäß einer Weiterbildung der Erfindung befindet sich am Übergang zwischen der zylindrischen Innenfläche des Ringkörpers und einer Stirnfläche des Ringes eine Abfasung.According to a further development of the invention, it is at the transition a chamfer between the cylindrical inner surface of the ring body and an end face of the ring.
Im folgenden sei die Erfindung anhand der Zeichnung näher erläutert :In the following the invention will be explained in more detail with reference to the drawing :

Flansch 6 und der Scheibe 9 ein röhrenförmiges Abstandsstück
10 montiert.The ring 4 is by means of a series of screw bolts 5 in ; fixed in its mounting position. These screw bolts 5, which i have the same angular distance from one another (and of which, for example, two or three are provided), connect one
annular flange 6 welded onto the exhaust pipe 6
and rests against the end face 4c of the ring 4 facing away from the tube 3, with an annular element 7 s of which the ring opening has a circumferential bevel 7a which, against the outer surface of the cup-shaped end region 3a of the tube 3, presses. Each screw bolt 5 is assigned a conical spring 8, which is located between the annular element 7 and a
Washer 9 mounted on screw bolt 5 is located. Furthermore, on each screw bolt 5 between the annular

Dies entspricht einem relativen Gleiten zwischen der Außenfläche 4b des Ringes 4 und der Innenfläche des becherförmigen Endbreiches 3a des Rohres 3· Die Federn 8 wirken Verschiebungen dieser Art entgegen. Auf diese Weise erhält man eine wirksame Verringerung der von dem Motor zum Auspuffschalldämpfer des Kraftfahrzeuges übertragenen Vibrationen.move others to a position in which their axes are not aligned. This corresponds to a relative Sliding between the outer surface 4b of the ring 4 and the inner surface of the cup-shaped end portion 3a of the tube 3 · The springs 8 counteract displacements of this kind. In this way an effective reduction is obtained that from the engine to the exhaust silencer of the motor vehicle transmitted vibrations.
