die
Die
Die Anschlusselemente solcher Gleichlaufgelenke, wie Wellenstummel oder Zapfen sind in Bezug auf ihre Dimension und Kosten nicht minimiert.The Connection elements of such constant velocity joints, such as stub shaft or Spigots are not minimized in terms of their dimension and cost.
Der Erfindung liegt die Aufgabe zugrunde, eine Lenkwelle mit einem Gleichlaufgelenk zu schaffen, deren Bauraum und Herstellungskosten minimiert sind.Of the Invention is based on the object, a steering shaft with a constant velocity joint to create, whose space and manufacturing costs are minimized.
Die Aufgabe wird mit einer Lenkwelle mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a steering shaft with the features of the claim 1 solved.
Dadurch dass das Gleichlaufgelenk in der Lenkwelle ein erstes Anschlusselement aufweist, das mit einer Welle der Lenkwelle eine Bildung eines elastisch-plastischen Längspressverband erlaubt, der minimale axiale Ausdehnung besitzt und wobei das erste Anschlusselement mit einem Mitnehmerelement des Gleichlaufgelenks drehfest verbunden ist oder einstückig mit dem Mitnehmerelement gebildet ist, ist eine Lenkwelle mit einem Gleichlaufgelenk geschaffen, die einfach und kostengünstig zu montieren ist und kleine Anschlussgeometrien des Gleichlaufgelenks aufweist.Thereby that the constant velocity joint in the steering shaft, a first connection element having, with a shaft of the steering shaft, a formation of an elastic-plastic Longitudinal compression band allowed, the minimum axial extent has and wherein the first connection element with a driver element the constant velocity joint is rotatably connected or in one piece is formed with the driver element, is a steering shaft with a Constant velocity joint created that is simple and inexpensive is to be mounted and small connection geometries of the constant velocity joint having.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
Die Welle ist bevorzugt mit dem ersten Anschlusselement, das einen Wellenanschluss in Form eines gehärteten Zapfens darstellt, verstemmt. Der Wellenanschluss weist bevorzugt ein längsgerichtetes Kerbzahnprofil auf über das die Welle mit einem rohrförmigen Ende gepresst ist und bevorzugt verstemmt wird.The Shaft is preferred with the first connection element, which has a shaft connection in the form of a hardened pin, caulked. The shaft connection preferably has a longitudinal direction Serrated profile on top of the shaft with a tubular End is pressed and preferably caulked.
Um insbesondere in Längsrichtung des ersten Anschlusselements Formschluss zu erzeugen, weist das erste Anschlusselement eine Umfangsnut auf, in die die Welle verstemmt werden kann und so axial unverschiebbar sitzt. Das rohrförmige Endstück der Welle ist weich und innen bevorzugt glatt, das heißt ohne Gegenverzahnung zu dem Kerbzahnprofil.Around in particular in the longitudinal direction of the first connection element To produce a positive fit, the first connection element has a circumferential groove, in which the shaft can be caulked and so axially immovable sitting. The tubular end piece of the shaft is soft and preferably smooth inside, that is without counter teeth to the serrated profile.
Der Aussendurchmesser des rohrförmigen Endes der Welle weist vor dem Verpressen ein Untermaß auf, das nach dem Verpressen kompensiert ist.Of the Outer diameter of the tubular end of the shaft has an undersize before pressing, after pressing is compensated.
Das drehfest mit dem ersten Anschlusselement verbundene Mitnehmerelement des Gleichlaufgelenks ist bevorzugt als glockenartiger, äußerer Gelenkkörper gebildet und einstückig mit diesem gebildet.The rotatably connected to the first connecting element driving element of the constant velocity joint is preferred as a bell-like, outer Joint body formed and integral with this educated.
Um den Schub auf das erst Anschlusselement bei der Darstellung des Längspresssitzes nicht auf Kugeln und deren Laufrillen in dem Gleichlaufgelenk z übertragen, ist vorgesehen, eine, die Axialkräfte ableitende Werkzeugeingriffsmöglichkeit, bevorzugt als Umfangswulst oder -schulter an dem ersten Anschlusselement vorzugsweise zwischen dem äußeren Gelenkkörper und dem ersten Anschlusselement vorzusehen.Around the thrust on the first connection element in the representation of Longitudinal press fit not on balls and their grooves transmitted in the constant velocity joint z, it is provided that one, the axial forces dissipating tool intervention possibility, preferably as a circumferential bead or shoulder on the first connection element preferably between the outer joint body and to provide the first connection element.
Die Schaftlänge des ersten Anschlusselements ist in einem besonders bevorzugten Ausführungsbeispiel der Lenkwelle und deren Gleichlaufgelenk nur etwa 30 mm bis 40 mm lang.The Shaft length of the first connection element is in a particular preferred embodiment of the steering shaft and its Constant velocity joint only about 30 mm to 40 mm long.
Ein zweites Anschlusselement des Gleichlaufgelenks ist mit einem Mitnehmerelement des Gleichlaufgelenks über eine Kerbverzahnung auf dessen Innenbohrung verpresst. Das Mitnehmerelement ist bevorzugt als innerer Gelenkkörper in Form einer kugelförmigen Nabe gebildet. Das zweite Anschlusselement ist bevorzugt als Nabenanschluss, einen Monoblock-Klemmanschluss bildend, ausgeführt.One second connection element of the constant velocity joint is with a driver element of the constant velocity joint via a serration on the Internal bore pressed. The driver element is preferably as internal Hinged body in the form of a spherical hub educated. The second connection element is preferably a hub connection, a Monoblock clamp connection forming executed.
Der innere Gelenkkörper weist zusammen mit dem zweiten Anschlusselement eine Länge, gemessen von einem Gelenkmittelpunkt des Gleichlaufgelenks von etwa 80 mm oder weniger auf.The inner joint body points together with the second connection element has a length measured from a joint center of the constant velocity joint of about 80 mm or less.
