Description
Aufgabe und Lösung Task and solution
Der Erfindung liegt die Aufgabe zugrunde, die Einstellmöglichkeit des Verzahnungseingriffes von Lenkmutter und Zahnsegment nach der Hauptpatentanmeldung weiterzuentwickeln. The invention is based on the object of the adjustment option the meshing engagement of the steering nut and toothed segment according to the main patent application to develop further.
Dabei sollen die die Segmentwelle aufnehmenden Lagerdeckel in hochbelasteten Lenkgetrieben von Nutzfahrzeugen so im Lenkgehäuse verankert werden, daß diese die hohen Lagerkräfte zuverlässig abstützen können.The bearing caps accommodating the segment shaft are to be subjected to high loads Steering gears of commercial vehicles are anchored in the steering housing that these the can reliably support high bearing forces.
Diese Aufgabe ist durch die in den Patentansprüchen angeführten Merkmale gelöst. This object is achieved by the features recited in the claims solved.
Nach der Erfindung weisen die am Lenkgehäuse anliegenden radialen Planflächen der beiden Lagerdeckel eine Stirnverzahnung auf. Die Lagerdeckel sind vorzugsweise aus Temperguß hergestellt und deren Stirnverzahnung ist gehärtet. Nach Einstellen der Verzahnung der Segmentwelle wird durch Einschrauben von Ronterringen die Stirnverzahnung der Lagerdeckel in das Gehäuse eingedrückt. Dadurch sitzen die Lagerdeckel unverrückbar im Lenkgehäuse fest und diese können die hohe wechselseitige Kräftebeaufschlagung einer Servolenkung aufnehmen, die über die Segmentwellenverzahnung eingeleitet wird. According to the invention, the radial bearings resting on the steering housing Flat surfaces of the two bearing caps have a face gear. The bearing caps are preferably made of malleable cast iron and the spur teeth are hardened. To The toothing of the segment shaft is set by screwing in counter rings the spur teeth of the bearing caps are pressed into the housing. This is how they sit Bearing cover immovable in the steering housing and these can be high reciprocal Take up the application of force to a power steering system via the segment shaft toothing is initiated.
Ein weiterer Vorteil des Lenkgetriebes besteht darin, daß die Verzahnung der Segmentwelle zum Ausgleich eines zu großen Verzahnungsspieles auch noch nach längerer Betriebszeit nachstellbar ist. Hierzu sind lediglich die beiden Konterringe heraus zuschrauben und nach Verdrehen der Lagerdeckel werden diese in ihrer neuen Stellung durch Einschrauben der Konterringe wieder formschlüssig mit dem Lenkgehäuse verankert. Another advantage of the steering gear is that the teeth the segment shaft to compensate for excessive backlash can be readjusted for a longer period of operation. Only the two counter rings are required for this unscrew and after turning the bearing cover, these are in their new Position by screwing in the counter rings again form-fitting with the steering housing anchored.
Erläuterung der Erfindung Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Explanation of the Invention The invention is based on a In the drawing illustrated embodiment explained in more detail.
Es zeigen: Fig. 1 einen Querschnitt durch eine Servolenkung mit der Segmentwelle.They show: FIG. 1 a cross section through a power steering system with the Segment shaft.
Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1. FIG. 2 shows a section along the line II-II in FIG. 1.
Fig. 3 einen Teilschnitt nach der Linie III-III in Fig. 1. FIG. 3 shows a partial section along the line III-III in FIG. 1.
In einem Lenkgehäuse 1 ist ein zugleich als Lenknutter wirkender Arbeitskolben 2 mit einer zahnstangenartigen Verzahnung 2A verschieblich gelagert. Der Arbeitskolben 2 führt in üblicher Weise bei Drehung einer nicht dargestellten Lenkspindel eine Axialbewegung aus. In a steering housing 1 is a steering nut acting at the same time Working piston 2 with a rack-like toothing 2A displaceably mounted. The working piston 2 leads in the usual way when rotating a not shown Steering spindle from an axial movement.
Die zahnstangenartige Verzahnung 2A am Arbeitskolben 2 steht im Zahneingriff mit einer Segmentwelle 3. Die Segmentwelle 3 ist mit einer zylindrischen Verzahnung 4 versehen. The rack-like toothing 2A on the working piston 2 is in meshing engagement with a segment shaft 3. The segment shaft 3 has cylindrical teeth 4 provided.
Diese Segmentwelle 3 ist über zwei als Exzenterbuchsen ausgebildete Lagerdeckel 5 und 6 in Wälzlagern 7 gelagert. Durch entsprechendes Verdrehen der exzentrischen Lagerdeckel 5 und 6 kann eine Spielfreiheit zwischen der Verzahnung 4 der Segmentwelle 3 und der Verzahnung 2A des Arbeitskolbens 2 eingestellt werden. Zwei mit einem Gewinde versehene Konterringe 8 und 9 dienen zum axialen Festlegen der beiden Lagerdeckel 5 und 6 im Lenkgehäuse 1.This segment shaft 3 is designed as two eccentric sockets Bearing caps 5 and 6 supported in roller bearings 7. By turning the eccentric bearing caps 5 and 6 can be a backlash between the teeth 4 of the segment shaft 3 and the toothing 2A of the working piston 2 can be adjusted. Two counter rings 8 and 9 provided with a thread are used for axial fixing of the two bearing caps 5 and 6 in the steering housing 1.
Nach der Erfindung sind am Lenkgehäuse 1 anliegende Planflächen 10 und 11 des Lagerdeckels 5 bzw. 6 mit einer gehärteten Stirnverzahnung 12 bzw. 13 versehen. According to the invention, flat surfaces 10 resting on the steering housing 1 are provided and 11 of the bearing cover 5 or 6 with hardened spur teeth 12 and 13, respectively Mistake.
Zum Einstellen werden die Lagerdeckel 5 und 6 über Mitnahmenuten 14 bzw. 15 verstellt, bis kein Spiel mehr zwischen den Verzahnungen 2A und 4 vorhanden ist. Anschließend werden die Lagerdeckel 5 und 6 durch den Konterring 8 bzw. 9 gesichert. Dabei drückt sich die Stirnverzahnung 12 bzw. 13 in eine zu der Planfläche 10 und 11 parallele Gegenfläche 16 bzw. 17 im Lenkgehäuse 1 ein. Die Lagerdeckel sind auf diese Weise spielfrei und bei den auftretenden hohen Zahnkräften unverrückbar im Lenkgehäuse 1 verankert. For adjustment, the bearing caps 5 and 6 are driven by driving grooves 14 or 15 adjusted until there is no more play between the teeth 2A and 4 is. Then the bearing caps 5 and 6 are secured by the counter ring 8 and 9, respectively. The spur toothing 12 or 13 is pressed into a to the plane surface 10 and 11 parallel mating surface 16 or 17 in the steering housing 1. The bearing caps are open in this way backlash-free and immovable in the high tooth forces that occur Steering housing 1 anchored.
Über einen Anlaufring 18 werden die Axialkräfte der Segmentwelle 3 aufgenommen. The axial forces of the segment shaft are transmitted via a stop ring 18 3 added.
