Die Erfindung betrifft eine Sicherungsvorrichtung für die genaue Verbindung der unteren Lenkspindel mit der Ritzelwe'ilp und der oberen Lenkspindel eines Lenkgetriebes. Die genannten Bauteile sind normalerweise schlecht zugänglich und schlecht sichtbar. The invention relates to a securing device for the precise connection of the lower steering spindle with the pinion shaft and the upper steering spindle of a steering gear. The components mentioned are normally difficult to access and difficult to see.
Die Verbindung der genannten Bauteile erfolgt üblicherweise durch Verklemmen mit einer Schraube, die die Gabel des Kardangelenkes der unteren Lenkspindel mit der Ritzelwelle des Lenkgetriebes und der oberen Lenkspindel verbindet.The connection of the above-mentioned components is usually made by clamping with a screw that connects the fork of the cardan joint of the lower steering spindle with the pinion shaft of the steering gear and the upper steering spindle.
Diese Art und Weise der Verbindung ist im Hinblick auf die Sicherheit des Fahrzeugs sehr kritisch, da der Monteuer beim Verbinden der unteren Lenkspindel des Lenkgetriebes mit der oberen Lenkspindel durch Sichtkontrolle nur unzureichend prüfen kann, ob die Schraube mit Sicherheit in eine Ringnut der Ritzelwelle und der oberen Lenkspindel eingreift.This type of connection is very critical with regard to the safety of the vehicle, since the fitter can only inadequately check by visual inspection whether the screw is securely engaged in an annular groove in the pinion shaft and the upper steering spindle when connecting the lower steering spindle of the steering gear to the upper steering spindle.
Wenn die genannte Klemmschraube nicht in diese Ringnut eingreift, besteht die große Gefahr, daß sich die Verbiirtfungsorgane voneinander lösen, was die Sicherheit des Fahrzeugs gefährlich beeinträchtigt, da die Drehbewegungen des Lenkrades nicht mehr übertragen werden können.If the clamping screw does not engage in this ring groove, there is a great risk that the locking elements will become detached from one another, which will endanger the safety of the vehicle, as the rotational movements of the steering wheel can no longer be transmitted.
Lösungen des genannten Problems bei Positionierung und Montage wurden bereits 1n den deutschen Gebrauchsmustern 87 16 393 und 88 14 897 sowie 1n der Italienischen Patentanmeldung 67432-A/87 der Anmelderin vorgeschlagen.Solutions to the above-mentioned problem of positioning and assembly have already been proposed in the German utility models 87 16 393 and 88 14 897 as well as in the Italian patent application 67432-A/87 of the applicant.
3e1 diesen Lösungen sind Sicherheitsvorrichtungen vorgesehen, die eine genaue Verbindung der unteren Lenkspindel mit der Rit-2elwf11e und der oberen Lenkspindel zulassen. Die Sicherungsvorrichtungen erfordern eine genaue Bearbeitung, was die Herstellungskosten beeinträchtigt.3e1 These solutions include safety devices that allow a precise connection of the lower steering shaft to the steering knuckle and the upper steering shaft. The safety devices require precise machining, which affects the manufacturing costs.

ßemaß der Erfindung 1st ein Sicherungsring 8 vorgesehen, der eine Bohrung 12 aufweist, über welche er auf einen zylindrischen Zapfen 9 der Ritzelwelle 6 aufgesetzt werden kann. Die Bohrung 12 1st an ihrem oberen Rand von zwei Schenkeln 13, 14 begrenzt, die elastisch in eine Ringnut 10 eingreifen, welche ifi den zylindrischen Zapfen 9 eingearbeitet ist. Auf diese Weise kann der Sicherungsring 8 sehr einfach befestigt werden, so daß er mit Schnappsitz auf dem Zapfen 9 der Ritzelwelle 6 sitzt und auf diesem frei drehbar gelagert ist.According to the invention, a locking ring 8 is provided which has a bore 12 through which it can be placed on a cylindrical pin 9 of the pinion shaft 6. The bore 12 is delimited at its upper edge by two legs 13, 14 which elastically engage in an annular groove 10 which is machined into the cylindrical pin 9. In this way, the locking ring 8 can be attached very easily so that it snaps onto the pin 9 of the pinion shaft 6 and is freely rotatable on it.
Von dem Sicherungsring 8 steht ein rieformter Ansatz 15 ab, in den ein Einschnitt 16 für den Durchtritt der Befestigungsschraube 5 eingearbeitet ist. Der Ansatz 15 greift zwischen die Schenkel der Verbindungsgabel 1 und erlaubt dadurch eine genaue Fixierung der Schraube 5, so daß diese mit Sicherheit in eine Ringnut 11 der Ritzelwelle 6 oder der nicht gezeigten Lenkspindel ei ngrei ft.A ring-shaped projection 15 protrudes from the locking ring 8, into which a notch 16 is machined for the passage of the fastening screw 5. The projection 15 engages between the legs of the connecting fork 1 and thereby allows the screw 5 to be fixed precisely so that it securely engages in an annular groove 11 of the pinion shaft 6 or the steering spindle (not shown).

Zunächst wird die Ritzelwelle 6 des Lenkgetriebes, auf die bereits der Sicherungsring 8 aufgesetzt ist, in die Gabel 1 eingesetzt. Anschließend wird die Schraube 5 in die Durchgangsbohrung 4 gesteckt. Vor Festziehen der Mutter 7 wird sichergestellt, daß das Durchstecken der Schraube S durch die Durchgangsbohrung 4 der Gabel 1 nicht durch den Ansatz 15 des Sicherungsringes 8 behindert worden ist.First, the pinion shaft 6 of the steering gear, on which the locking ring 8 is already placed, is inserted into the fork 1. Then the screw 5 is inserted into the through hole 4. Before tightening the nut 7, ensure that the insertion of the screw S through the through hole 4 of the fork 1 is not impeded by the projection 15 of the locking ring 8.
