Abstract

With a hollow shaft (1) made of plastic with a permanently connected flange (2) made of a metal which has a tubular stub (3) inserted into the hollow shaft (1), a multi-groove connection is provided between these two elements by means of strips (4) which are arranged on the circumference of the tubular stub (3), engage in longitudinal grooves (5) which form slits in the hollow shaft (1), project from these grooves in the radial direction and the lateral surface (4.1) of which is given a profile which provides grip for a plastics binding (6), arranged in the region of the longitudinal groove, of the hollow shaft (1). <IMAGE>

Description

Hohlwelle aus Kunststoff mit einem Festflansch ausHollow shaft made of plastic with a fixed flange

Metall Die Erfindung betrifft eine Hohlwelle gemäß dem Oberbegriff des Patentanspruchs 1.Metal The invention relates to a hollow shaft according to the preamble of claim 1.

Eine derartige aus Einzelteilen verschiedenen Materials gebildete Hohlwelle kommt, u.a. aus Gründen des Leichtbaus, beispielsweise als Lenk- oder Kardanwelle für Kraftfahrzeuge in Betracht. Dabei stellt sich das Problem einer drehfesten und zugleich axialen Fixierung des Flansches an der Hohlwelle, sofern diese als fertiges Bauteil mit dem Flansch vereinigt werden können soll-.Such one formed from individual parts of different material Hollow shaft comes, among other things, for reasons of lightweight construction, for example as a steering or Cardan shaft for motor vehicles into consideration. The problem arises here non-rotatable and at the same time axial fixation of the flange on the hollow shaft, provided this should be able to be combined with the flange as a finished component.

Der Erfindung liegt die Aufgabe zugrunde, diese Forderung bei einer Hohlwelle der eingangs genannten Art mit geringstmöglichem Aufwand zu erfüllen.The invention is based on the object of this requirement in a To meet the hollow shaft of the type mentioned with the least possible effort.

Diese Aufgabe ist gemäß dem Kennzeichen des Patentanspruchs 1 gelöst in der Erkenntnis, daß die Vielnutverbindung im vorliegenden Anwendungsfall zwar zum Wellenende hin offene, d.h. in Axialrichtung die Leisten freigebende Längsnuten bedingt, daß jedoch hiermit in Eingriff die Leisten bloß in Radialrichtung über den Wellenumfang herauszuragen brauchen, um sie einfach durch Formschluß mit einer nach dem Einschieben des Rohrstutzens mit der Hohlwelle stoffschlüssig vereinigbaren Bandage in Axialrichtung fixieren zu können. Das wird im nachfolgenden Ausführungsbeispiel der Erfindung und deren in den Unteransprüchen gekennzeichneten bevorzugten Ausgestaltungen weiter verdeutlicht. Hierzu zeigt die Zeichnung in Fig. 1 teils im Längsschnitt das mit einem Festflansch versehene Ende einer Hohlwelle, Fig. 2 das Wellenende gemäß Fig. 1 in Explosionsdarstellung.This object is achieved according to the characterizing part of claim 1 knowing that the multi-groove connection in the present application Longitudinal grooves open towards the shaft end, i.e. longitudinal grooves that release the strips in the axial direction conditional, however, that this engages the strips only in the radial direction need to protrude from the circumference of the shaft, simply by form-fitting with a After inserting the pipe socket, unite with the hollow shaft in a materially bonded manner To be able to fix the bandage in the axial direction. This is done in the following exemplary embodiment of the invention and its preferred embodiments characterized in the subclaims further clarified. The drawing in Fig. 1 partly in longitudinal section the end of a hollow shaft provided with a fixed flange, FIG. 2 the shaft end according to FIG. 1 in an exploded view.

Eine Hohlwelle 1 aus Kunststoff, z.B. Kunstharz als Matrix von Verstärkungsfasern, wie Glas-,Kohle- o. dgl.A hollow shaft 1 made of plastic, e.g. synthetic resin as a matrix of reinforcing fibers, like glass, coal or the like.

Fasern, ist gemäß Fig. 1 mit einem Festflansch 2 aus Metall versehen, der einen in das Wellenende eingeschobenen Rohrstutzen 3 aufweist. Dieser ist gegen Verdrehen durch eine Vielnutverbindung gesichert, bei der, wie insbesondere Fig. 2 veranschaulicht, am Umfang des Rohrstutzens 3 angeordnete Leisten 4 in Längsnuten 5 eingreifen, welche die Hohlwelle 1 am Ende aufschlitzen.Fibers, is provided according to Fig. 1 with a fixed flange 2 made of metal, which has a pipe socket 3 pushed into the shaft end. This is against Rotation secured by a multi-groove connection, in which, as in particular Fig. 2 illustrates strips 4 arranged in longitudinal grooves on the circumference of the pipe socket 3 5 intervene, which slit open the hollow shaft 1 at the end.

Beispielsweise sind die Leisten 4 auf den mit entsprechenden Längsschlitzen versehene£-hrstützen 3 bloß aufgesteckt. Der Zusammenbau von Hohlwelle 1 und Festflansch 2 erfordert folglich nach dem Einschieben des mit den Leisten 4 bestückten Rohrstutzens 3 bloß dessen Fixierung in Axialrichtung. Diese Fixierung ist mittels einer im Bereich der Längsnuten 5 aufgebrachten Bandage 6 erreicht, welche aus demselben Material wie die Hohlwelle 1 besteht und folglich hiermit in Stoffschlußverbindung steht. Die axiale Verbindungssicherheit zwischen der Bandage 6 und den z.B. von dieser zugleich in Radialrichtung an den Rohrstutzen 3 gebundenen Leisten 4 ist im wesentlichen ein Formschluß dadurch, daß deren Mantelfläche 4.1 für die Bandage 6 griffig profiliert ist, vorzugsweise durch die dargestellte Zahnung, und zumindest die Profilierung den Wellenumfang überragt. Die dargestellte Zahnung gewährleistet die größtmögliche Verbindungssicherheit im Falle einer als Radialfaserwicklung ausgeführten Bandage 6, wobei die Radialfaserwicklung un- ter Spannung stehen kann, um zusätzlich das geschlitzte und folglich federnde Spannbacken 1.1 aufweisende Wellenende über dem Rohrstutzen 3 zusammenzupressen.For example, the strips 4 are on the with corresponding longitudinal slots provided ear supports 3 just plugged on. The assembly of hollow shaft 1 and fixed flange 2 consequently requires after the insertion of the pipe socket equipped with the strips 4 3 merely its fixation in the axial direction. This fixation is by means of one in the area of the longitudinal grooves 5 applied bandage 6, which is made of the same material how the hollow shaft 1 exists and is consequently in a material connection therewith. The axial connection security between the bandage 6 and e.g. at the same time in the radial direction of the pipe socket 3 bound strips 4 is essentially a positive fit in that the outer surface 4.1 profiled for the bandage 6 with good grip is, preferably by the teeth shown, and at least the profiling protrudes beyond the circumference of the shaft. The toothing shown ensures the greatest possible Connection security in the case of a bandage designed as a radial fiber winding 6, with the radial fiber winding un- the tension can stand to additionally the slotted and consequently resilient clamping jaws 1.1 having the shaft end to be pressed together over the pipe socket 3.
