Abstract

A rigid coupling between a shaft made of plastic and a shaft made of metal which is inserted via an end shank (2) into the plastic shaft, which is in the form of a hollow cylinder, at least at the coupling end (1), has, as the connecting means between the two shaft-coupling parts, a sleeve (3) which is in engagement, on the one hand, with the end shank (2), via a multi-groove connection, and, on the other hand, with the hollow-cylindrical shaft end (1), via at least one strip (3.1) extending in a longitudinal groove (6) forming a slot in said shaft end and firmly fixed on the outer surface of the sleeve and which is secured against axial movements by a silent ratchet assigned to the hollow-cylindrical shaft end (1). <IMAGE>

Description

Kupplung zwischen einer Kunststoff- und einer Metall-Coupling between a plastic and a metal

Welle Die Erfindung betrifft eine Kupplung gemäß dem Oberbegriff des Patentanspruchs 1.Shaft The invention relates to a coupling according to the preamble of Claim 1.

Bei einer derartigen Kupplung stellt sich das Problem ausreichender Verbindungssicherheit zwischen den beiden Wellen u.a. wegen der unterschiedlichen Torsionssteifigkeit ihrer Werkstoffe. Es wird daher bisher weitestgehend von einer Vereinigung der Wellen Gebrauch gemacht, d.h. deren Kupplung unlösbar ausgebildet. Das schrank naturgemäß den Anwendungsbereich der Kunststoff-Welle ein.With such a coupling the problem arises more sufficiently Connection security between the two waves, among other things because of the different Torsional stiffness of their materials. It is therefore largely from a Use was made of the union of the shafts, i.e. their coupling was designed to be inseparable. Naturally, this restricted the area of application of the plastic shaft.

Der Erfindung liegt daher die Aufgabe zugrunde , eine Kupplung der eingangs genannten Art lösbar auszubilden ohne Beeinträchtigung der Verbindungssicherheit.The invention is therefore based on the object of providing a clutch of to be designed releasably without impairing the connection security.

Diese Aufgabe ist gemäß dem Kennzeichen des Patentanspruchs 1 gelöst durch Einführung eines Verbindungsteils in solcher Verzahnung mit den Kupplungsteilen beider Wellen, daß durch bloßes axiales Verschieben derselben relativ zueinander torsionssteife Formschlußverbindungen zwischen allen Teilen entstehen und bei Bedarf wieder lösbar sind, wobei schließlich das Klemmgesperre als Gegenlager zusätzlich für Kraftschluß zumindest zwischen diesem Verbindungsteil und dem Kupplungsteil der Kunststoff-Welle sorgt. Erforderlichenfalls ist hierbei zugleich eine Sicherung gegen axiale Bewegungen aller Teile untereinander durch ein Klemmgesperre der im Unteranspruch gekennzeichneten Ausführungsform erreichbar.This object is achieved according to the characterizing part of claim 1 by introducing a connecting part in such a toothing with the coupling parts both shafts, that by simply moving them axially relative to each other Torsionally rigid interlocking connections between all parts are created and if necessary are releasable again, with finally the locking mechanism as a counter bearing in addition for frictional connection at least between this connecting part and the coupling part the plastic shaft ensures. If necessary, this is also a backup against axial movements of all parts with each other by a locking mechanism of the im The embodiment characterized in the dependent claim can be achieved.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels weiter erläutert. Dabei zeigt die Zeichnung in Explosionsdarstellung die zur lösbaren, starren Kupplung einer Metall- mit einer Kunststoff-Welle vorgesehenen Teile, nämlich ein hohlzylindrisches Wellenende 1 der u.U. vollständig hohlen Kunststoff-Welle, einen Endschaft 2 der massiven Metall-Welle und als deren Verbindungsmittel eine Metallhülse 3 sowie eine durch eine Zugschraube 4 zusammendrückbare Spannbacke 5. Auf den mit Leisten versehenen Endschaft 2 ist die entsprechende Nuten aufweisende Metallhülse 3 steckbar, so daß dann eine sog. Kerbverzahnung derselben besteht. Der Endschaft 2 ist mit aufsitzender MetallhÜlse 3 in das hohlzylindrische Wellenende 1 einsteckbar, wobei dann auch eine Nutverbindung entsteht, und zwar über eine an der Hülsenmantelfläche angeformte Leiste 3.1 und eine das Wellenende aufschlitzende Längsnut 6.The invention is further developed below with the aid of an exemplary embodiment explained. The drawing shows in an exploded view the detachable, rigid coupling of a metal with a plastic shaft provided parts, namely a hollow cylindrical shaft end 1 of the possibly completely hollow plastic shaft, an end shaft 2 of the solid metal shaft and as its connecting means a Metal sleeve 3 and a clamping jaw 5 which can be compressed by a tension screw 4. On the end shaft 2, which is provided with strips, the corresponding grooves are located Metal sleeve 3 can be plugged in, so that a so-called serration then exists of the same. The end shaft 2 is with a seated metal sleeve 3 in the hollow cylindrical shaft end 1 can be inserted, in which case a groove connection is also created, namely via an the sleeve outer surface molded bar 3.1 and a slit end of the shaft Longitudinal groove 6.

Die Spannbacke 5 wird nach dem Zusammenstecken dieser drei Teile auf das Ende des hohlzylindrischen Wellenendes 1 geschoben und sorgt dann durch entsprechendes Anziehen der Zugschraube 4 mittels der zugehörigen Mutter 4.1 für Kraftschluß zwischen sämtlichen Teilen, umso wirkungsvoller, sofern auch noch die Metallhülse 3 (wie dargestellt) längsgeschlitzt und damit federnd nachgiebig ist.The clamping jaw 5 is opened after these three parts have been put together pushed the end of the hollow cylindrical shaft end 1 and then takes care of the corresponding Tighten the tension screw 4 by means of the associated nut 4.1 for frictional connection between all parts, all the more effective if the metal sleeve 3 (such as shown) is longitudinally slotted and thus resilient.

Um bei dieser Kupplung axiale Bewegungen aller Teile gegeneinander sicher auszuschließen, brauchen bloß Materialaussparungen 7 solcher Form vorgesehen zu sein, daß die Zugschraube 4 das hohlzylindrische Wellenende 1, die Metallhülse 3 mit der Leiste 3.1 und den Endschaft 2 jeweils teilweise durchquert und damit in deren Axialrichtung eine Gesperrefunktion erfüllt.In order to achieve axial movements of all parts against each other in this coupling to exclude safely, only material recesses 7 need to be provided of such a shape to be that the tension screw 4, the hollow cylindrical shaft end 1, the metal sleeve 3 with the bar 3.1 and the end shaft 2 each partially traversed and thus fulfills a locking function in the axial direction.

Die vorbeschriebene Kupplung wird bevorzugt bei Kfz-Lenkwellen angewendet, deren Grundkörper aus Faserverbundkunststoff besteht.The coupling described above is preferably used for motor vehicle steering shafts, whose main body consists of fiber-reinforced plastic.
