Description
Die
Erfindung betrifft ein Verfahren zum Herstellen einer Verbindung
zwischen einer Außenhülse einer
Axialverschiebeeinheit zur Drehmomentübertragung und einem Wellenrohr.
Die Erfindung steht im Zusatzverhältnis zum Hauptpatent
Axialverschiebeeinheiten dieser Art umfassen eine Außenhülse mit innenliegenden Kugelbahnen, einen Zapfen mit außenliegenden Kugelbahnen, und in Paaren von Kugelbahnen laufende, in einem Käfig gehaltene drehmomentübertragende Kugeln, die bei einer Axialverschiebung zwischen Außenhülse und Zapfen in den Paaren von Kugelbahnen abrollen.Axialverschiebeeinheiten This type includes an outer sleeve with internal ball tracks, a pin with external ball tracks, and in pairs of ball tracks running, held in a cage torque-transmitting Spheres, the case of an axial displacement between the outer sleeve and Roll off pins in the pairs of ball tracks.
Es ist bereits bekannt, Außenhülsen von Axialverschiebeeinheiten unmittelbar in Rohrwellen einzuschweißen. Hierbei ist eine genaue Bearbeitung der Paßflächen an der Außenhülse und im Rohr erforderlich, damit die Außenhülse zentriert und mit exakter Axialität im Rohrende einsitzt, so daß eine unwuchtfreie Verbindung entsteht.It is already known, outer sleeves of To weld Axialverschiebeeinheiten directly in tube shafts. in this connection is a precise machining of the mating surfaces on the outer sleeve and required in the tube, so that the outer sleeve centered and with more precise axiality einitzt in the pipe end, so that a unbalance connection is created.
Aus
der
Aufgabe der vorliegenden Erfindung ist es, Verfahren zum Verbinden von Außenhülsen von Axialverschiebeeinheiten mit Rohrwellen vorzuschlagen, die kostengünstig durchzuführen sind und zu leichtbauenden Verbindungsanordnungen führen.task The present invention is a method for connecting outer sleeves of To propose Axialverschiebeeinheiten with tube shafts, which are inexpensive to perform and lead to lightweight connection arrangements.
Die Lösung besteht in einem Verfahren zum Herstellen einer Verbindung zwischen einer Außenhülse einer Axialverschiebeeinheit und einem Wellenrohr, wobei die Außenhülse mit einer umfänglichen Verbindungsfläche hergestellt wird, wobei das Wellenrohr mit einem Rohrende mit größerem Durchmesser als dem der Verbindungsfläche versehen wird, und wobei das Rohrende des Wellenrohres mit radialem Abstand über die Außenhülse geschoben wird und mittels eines Impulsschweißverfahrens radial reduziert und mit der Außenhülse verschweißt wird. Hiermit wird ein Verfahren bereitgestellt, mit dem Außenhülsen von Axialverschiebeeinheiten in einem offenen Ende einer Rohrwelle festgelegt werden können. Dies ist insbesondere bei Rohrwellen mit großem Durchmesser günstig, wie sie in Längsantriebswellen von Kraftfahrzeugen verwendet werden. Die entsprechende Rohrwelle, die insgesamt kleineren Durchmesser haben kann als die Außenhülse, kann hierbei ein im Durchmesser aufgeweitetes Ende aufweisen, in das sich die Außenhülse mit radialem Spiel einsetzen läßt. Nachdem die Außenhülse konzentrisch in das Rohrende eingesetzt ist, wird ein bekanntes Impulsschweißverfahren durchgeführt, dessen Wirkung hier auf das Rohrende beschränkt wird. Bei der impulsartigen radialen Stauchung des Rohrendes kommt es hierbei zu einer Schweißverbindung zwischen dem reduzierten Rohrende und der umfänglichen Verbindungsfläche der Außenhülse. Die umfängliche Verbindungsfläche kann rein zylindrisch oder aber im Querschnitt profiliert ausgeführt sein. In letzterem Fall entsteht zusätzliche ein torsionsbelastbarer Formschluß zwischen Rohrende und Außenhülse. Die genannte Profilierung kann insbesondere dadurch gebildet werden, daß die Außenhülse ihrerseits ein Blechumformteil ist, dessen Außenkontur durch die Querschnittsform der Kugelbahnen bestimmt wird. Dies hat den besonderen Vorteil, daß das flächig verschweißte Rohrende wesentlich zur Formsteifigkeit der Außenhülse beiträgt, die bei Blechumformaußenhülsen zunächst geringer liegt als bei Massivaußenhülsen.The solution consists in a process for establishing a connection between an outer sleeve of a Axialverschiebeeinheit and a shaft tube, wherein the outer sleeve with a circumferential interface is produced, wherein the shaft tube having a pipe end with a larger diameter than that of the interface is provided, and wherein the tube end of the shaft tube with radial Distance over the outer sleeve is pushed and by means of a pulse welding process radially reduced and welded to the outer sleeve. Herewith a method is provided, with the outer sleeves of Axialverschiebeeinheiten fixed in an open end of a tubular shaft can be. This is particularly favorable for large diameter tube shafts, such as in longitudinal drive shafts used by motor vehicles. The corresponding tube shaft, which may have smaller overall diameter than the outer sleeve, can in this case have a widened in diameter end in the the outer sleeve with radial Play. After this the outer sleeve concentric is inserted into the pipe end, a well-known pulse welding process carried out, its effect is limited here to the pipe end. At the impulsive radial compression of the pipe end, this is a welded joint between the reduced tube end and the circumferential connection surface of the outer sleeve. The extensive Interface can be purely cylindrical or profiled in cross-section. In the latter case arises additional a torsionally resilient positive connection between the pipe end and outer sleeve. The mentioned profiling can be formed in particular by the fact that the outer sleeve in turn a Blechumformteil is whose outer contour by the cross-sectional shape of Ball tracks is determined. This has the particular advantage that the surface welded pipe end contributes significantly to the stiffness of the outer sleeve, initially lower in Blechumformaußenhülsen lies as with solid outer sleeves.
Nach einer günstigen Ausführung kann vor dem Einsetzen der Außenhülse in das offene Rohrende zunächst ein Deckel eingesetzt werden, der den Rohrquerschnitt verschließt. Dieser kann gegen einen Innenabsatz im Rohr angelegt werden, wobei dieser in einem axialen Bereich liegen sollte, in dem sich die radiale Stauchung des Rohrquerschnittes durch das Impulsschweißverfahren noch auswirkt. Hierdurch wird der Deckel, wie die Außenhülse im Rohr, zusätzlich eingespannt. Als Wellenwerkstoff für die Rohrwelle kann eine Leichtmetallegierung gewählt werden.To a cheap one execution can before inserting the outer sleeve in the open pipe end first a lid are used, which closes the pipe cross-section. This Can be applied against an inner shoulder in the pipe, this should be in an axial region in which the radial Compression of the tube cross-section by the pulse welding process still affects. As a result, the lid, as the outer sleeve in the tube, additionally clamped. As a shaft material for the tubular shaft, a light metal alloy chosen become.
Bevorzugt wird ein Magnetimpulsschweißverfahren zur Beschleunigung des Rohrkörpers verwendet. Dies setzt ein elektrisch leitendes Material für den Rohrkörper voraus. Beim Magnetimpulsschweißverfahren wird elektrische Energie in elektrischen Kondensatoren gespeichert und über eine Entladeschaltung auf einen spulenförmigen Induktor gegeben, welcher mit Abstand radial außerhalb der Rohrwelle und der Außenhülse angeordnet ist. Hierdurch wird im Induktor in kürzester Zeit ein extrem starkes Magnetfeld aufgebaut. Dieses übt eine hohe Beschleunigungskraft auf den Rohrkörper aus, der nach radial innen im Induktor, das heißt auf die Längsachse der Rohrwelle gerichtet ist. Es kann auch ein Sprengimpulsschweißverfahren (pyrotechnisches Verfahren) verwendet werden. Hierbei ist nur die Schweißbarkeit der Materialien von Rohrwelle und Außenhülse zu beachten. Beim Sprengschweißverfahren wird eine Sprengstoffmasse, in der chemische Energie gespeichert ist, radial außen an der Rohrwelle in Bezug auf die Längsachse der Welle angebracht und zur Detonation gebracht. Hierbei kann radial außerhalb der Rohrwelle eine Verdämmung, z. B. in Form eines auf Rohrkörper und Außenhülse aufgeschobenen Rohres vorgesehen sein. Die bei der Detonation stattfindende Druckerhöhung übt eine hohe Beschleunigungskraft auf den Rohrkörper aus, die radial in Richtung auf die Längsachse der Rohrwelle gerichtet sein soll.Preferably, a magnetic pulse welding method is used to accelerate the tubular body. This requires an electrically conductive material for the tubular body. In the magnetic impulse welding method, electrical energy is stored in electrical capacitors and applied via a discharge circuit to a coil-shaped inductor, which is arranged at a distance radially outside the tubular shaft and the outer sleeve. As a result, an extremely strong magnetic field is built up in the inductor in the shortest possible time. This exerts a high acceleration force on the tubular body, which is directed radially inward in the inductor, that is, on the longitudinal axis of the tubular shaft. An explosive pulse welding method (pyrotechnic method) may also be used. Here, only the weldability of the materials of tube shaft and outer sleeve is to be considered. In the explosive welding process is an explosive mass in the chemi cal energy is stored, mounted radially on the outside of the tube shaft with respect to the longitudinal axis of the shaft and detonated. Here, radially outside the tube shaft, a damming, z. B. be provided in the form of a pushed onto the tubular body and outer sleeve tube. The pressure increase occurring during the detonation exerts a high acceleration force on the tubular body, which is intended to be directed radially in the direction of the longitudinal axis of the tubular shaft.
