Abstract
Description
Die Erfindung bezieht sich auf eine Welle-Nabe-Verbindung sowie weiterhin auf eine Zahnstange mit einem Anschlagring zur mechanischen Hubbegrenzung. Ferner bezieht sich die Erfindung auf ein mehrteiliges Lenkungsgehäuse.The The invention relates to a shaft-hub connection and furthermore on a rack with a stop ring for mechanical stroke limitation. Furthermore, the invention relates to a multi-part steering housing.
Bei
Zahnstangenlenkungen, die vor allem in Personenkraftfahrzeugen und
leichten Nutzkraftfahrzeugen eingesetzt werden, ist die Zahnstange
in einem Lenkgetriebegehäuse aufgenommen, das am Fahrzeug
befestigt ist. Die Zahnstange ist relativ zu dem Lenkgetriebegehäuse
axial verschiebbar, um einen Lenkwinkel an den Rädern des
Fahrzeugs einzustellen. Hierzu sind an die Enden der Zahnstange zwei
Spurstangen gelenkig angekoppelt, die zu den Fahrzeugrädern
führen. Die Zahnstange weist ferner einen Verzahnungsabschnitt
auf, der mit einem Lenkungsritzel einer Lenkwelle kämmt,
um einen fahrerseitigen Lenkbefehl an die Fahrzeugräder
zu übertragen. Bei elektromechanischen Lenkungen unterstützt
ein Elektromotor die Lenkbewegung. Das Motormoment wird beispielsweise über
einen Riementrieb auf eine Kugelgewindemutter übertragen,
die mit einem an der Zahnstange ausgebildeten Spindelabschnitt in
Eingriff steht. Derartige Zahnstangenlenkungen sind beispielsweise
aus der aus der
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, die Befestigung eines Anschlagrings an der Zahnstange zu vereinfachen.In front In this background, the invention is based on the object, the Fixing a stop ring on the rack to simplify.
Diese Aufgabe wird durch eine Welle-Nabe-Verbindung gemäß Patentanspruch 1 gelöst. Hiernach werden Welle und Nabe durch ein Drahtstück zueinander fixiert, das zwischen einer an einem Außenumfangsabschnitt der Welle ausgebildeten umlaufenden Nut und einer an einem Innenumfangsabschnitt der Nabe ausgebildeten umlaufenden Nut angeordnet ist. Die Nut der Nabe und/oder die Nut der Welle weist bzw. weisen einen gotischen Profilquerschnitt auf. Das im Querschnitt kreisförmige Drahtstück steht dabei mit jeder gotischen Nut in doppeltem Linienkontakt.These Task is by a shaft-hub connection according to claim 1 solved. After this, the shaft and hub are replaced by a piece of wire fixed to each other, between one at an outer peripheral portion the shaft formed circumferential groove and one on an inner peripheral portion the hub formed circumferential groove is arranged. The groove of Hub and / or the groove of the shaft has or have a gothic Profile cross section on. The circular piece of wire in cross-section stands with each gothic groove in double line contact.
Die erfindungsgemäße Welle-Nabe-Verbindung gestattet eine einfache Herstellung und Überprüfung der Nutkontur, da eine eindeutige Anlage des Drahtstücks in den Nuten erzielt wird. Die Geometrie der Nutkontur kann in der laufenden Fertigung sehr effizient über die Profilform und eindeutig über das Drahtmaß bestimmt werden. Das Prüfmittel liegt hierbei unter dem Druckwinkel des Profils eindeutig in der Nut an. Dies ist bei einer halbrunden Nut nicht möglich.The shaft-hub connection according to the invention allowed a simple preparation and verification of Groove contour, as a clear investment of the piece of wire in the grooves is achieved. The geometry of the groove contour can be seen in the running production very efficiently via the profile shape and clearly determined by wire gauge. The test equipment lies under the pressure angle of the Profils clearly in the groove. This is at a semicircular groove not possible.
Die Nutkonfiguration ist ferner verhältnismäßig unempfindlich gegen Fertigungstoleranzen.The Groove configuration is also proportionate insensitive to manufacturing tolerances.
Die erfindungsgemäße Welle-Nabe-Verbindung eignet sich hervorragend für eine einfache und kostengünstige Befestigung eines Anschlagrings auf einer Zahnstange einer Fahrzeuglenkung. Die vorgeschlagene Verbindung kann jedoch auch zu anderen Zwecken, beispielsweise zur Befestigung von zwei Gehäuseteilen aneinander eingesetzt werden.The shaft-hub connection according to the invention is suitable Great for a simple and inexpensive Fixing a stop ring on a rack of a vehicle steering. However, the proposed connection may also be used for other purposes, for example, for attachment of two housing parts to each other be used.
Vorteilhafte Ausgestaltungen sind in weiteren Patentansprüchen angegeben.advantageous Embodiments are specified in further claims.
So kann beispielsweise jede gotische Nut im Profilquerschnitt durch zwei Bogensegmente gebildet werden, die nicht-tangential aneinander anschließen. Jedoch kann eine gotische Form auch durch einen ellipsenförmigen Profilquerschnitt erzielt werden. Möglich sind insbesondere auch Kreisbogensegmente, deren Erzeugungsmittelpunkte zueinander versetzt sind.So For example, every Gothic groove in the profile cross section through two arc segments are formed which are non-tangential to each other connect. However, a gothic form can also through an elliptical profile cross section can be achieved. Possible are in particular also circular arc segments, their production centers offset from each other.
Das Verhältnis des Krümmungsradius der Nut im Profilquerschnitt zum Drahtdurchmesser im Bereich des Kontakts des Drahtstücks mit der gotischen Nut liegt vorzugsweise im Bereich von 0,4 bis 0,6.The Ratio of the radius of curvature of the groove in the profile cross section to the wire diameter in the area of the contact of the piece of wire with the Gothic groove is preferably in the range of 0.4 to 0.6.
Zur Erleichterung der Montage kann die Nabe eine zu ihrer Nut tangentiale Drahtzufuhröffnung aufweisen.to To facilitate assembly, the hub can be tangential to its groove Have wire feed opening.
Weiterhin kann zwischen der Drahtzufuhröffnung und der Nut der Nabe ein gegenüber dem Nutquerschnitt erweiterter Übergangsbereich vorgesehen sein, um eine Einführung des Drahtstücks zwischen den Nuten zu erleichtern.Farther can between the wire feed opening and the groove of the hub an opposite the groove cross-section extended transition region be provided to initiate the piece of wire between the grooves to facilitate.
Durch eine axiale Freistellung der Drahtzufuhröffnung und des Übergangsbereichs kann die Montage des Drahtstücks weiter erleichtert werden.By an axial release of the wire feed opening and the transition region the assembly of the piece of wire can be further facilitated.
