Description
Die Erfindung bezieht sich auf eine Lamellenkupplung für eine Kraftstoffeinspritzpumpe einer Brennkraftmaschine mit einem An- und einem Abtriebsflansch, die beide fest mit jeweils einem Lamellenpaket verschraubt sind deren gegenseitige Verbindung über ein wiederum fest an den beiden LameUenpaketen Angeschraubtes Zwischenstück erfolgt, wobei die Schrauben zur Befestigung der Lamellenpakete am An- bzw. Antriebsflansch einerseits sowit am Zwischenstück andererseits gegeneinander winkelversetzt angeordnet find.The invention relates to a multi-plate clutch for a fuel injection pump of an internal combustion engine with an input and an output flange, both of which are fixed with a disk pack each Their mutual connection is screwed again firmly to the two LameUenpaketen The screwed-on intermediate piece takes place, whereby the screws for fastening the plate packs to the or drive flange on the one hand and on the intermediate piece on the other hand, find arranged at an angle offset from one another.
Derartige, z. B. aus der Zeitschrift Krafthand Heft 10. 1969. S. 570 bekannte Kupplungen sind notwendig, um die sich aus den Bearbeitungstoleranzen ergebenden Fluchtungsfehler zwischen der An- und Abtriebswelle auszugleichen. Aus der Lagerung des Zwischenstückes in den LameUenpaketen folgert ein nur schwach gedämpftes Masse-Federsystem. Aus der Eigenheit der Einspritzpumpe ergibt sich ein pulsierendes Drehmoment, das durch die Fluchtungsfehler der An- und Abtriebswelten sowie Flüchtlings- und Montagetoleranren der Kupplung eine Schwingungserregung auch in axialer Richtung bewirkt. Diese gegebenenfalls durch Schrägverzahnungen im Antrieb der Einspritzpumpe verstärkten Axialschwingungen erfolgen mit einer Frequenz, die je nach Drehzahl der Eigenfreqtsnz des vom Zwischenstück und den LameUenpaketen gebildeten Masse-Federsystems entspricht, so daß es zu Resonanzerscheinungen kommt, die bei hohem Drehmoment der Einspritzpumpe und damit starker Anregung zu Dauerbrüchen der Lamellen führen s können.Such, z. B. from Krafthand magazine 10. 1969. S. 570 known couplings are necessary to the misalignment between the input and output shafts resulting from the machining tolerances balance. From the storage of the intermediate piece in the LameUenpaketen only weakly follows damped mass-spring system. The peculiarity of the injection pump results in a pulsating torque, This is due to the misalignment of the input and output worlds as well as refugee and assembly tolerances the coupling causes vibration excitation also in the axial direction. This if necessary through Helical gears in the drive of the injection pump, increased axial vibrations occur with a Frequency that depends on the speed of the eigenfreqtsnz of the mass-spring system formed by the intermediate piece and the LameUenpaketen, so that it corresponds to Resonance occurs when the injection pump torque is high and therefore stronger Excitation can lead to fatigue fractures of the lamellas.
Somit hegt der Erfindung die Aufgabe zugrunde, bei einer Kupplung der eingangs beschriebenen Art gegebenenfalls auftretende Axialschwingungen des Zwischenstückes mit ihren schädlichen RückwirkungenThus, the invention is based on the object, in a coupling of the type described at the outset possibly occurring axial vibrations of the intermediate piece with their harmful repercussions

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zumindest bei einem Lamellenpaket in dem zwischen den Befestigungsschrauben liegenden Bereich des An- bzw.

Of course, it is useful, if not only a damping element is provided, but several such elements are arranged.
