Abstract
Description
Die Erfindung betrifft ein Gehäuse für ein hydraulisch unterstütztes Zahnstangenlenkgetriebe nach dem Oberbe griff des Patentanspruches.The invention relates to a housing for a hydraulic supported rack and pinion steering gear according to the Oberbe handle of the claim.
Ein solches Gehäuse ist durch DE 40 19 693 bekannt gewor den. Bei diesem bekannten Gehäuse ist der Zylinder aus einem Strangpreßprofil gebildet, indem zusätzlich zur Zy linderbohrung zwei Hydraulikkanäle parallel zur Zylinder bohrung ausgebildet sind. Das Strangpreßprofil ist an der dem Ritzelventilgehäuse zugewandten Seite soweit abgear beitet, daß nur die zwei Hydraulikleitungen verbleiben, die dann in Richtung zur Mittelachse des Ventilritzelge häuses gebogen und mit letzterem durch Umgießen bis in den benachbarten zylindrischen Bereich des vollständigen Strangpreßprofils hinein verbunden sind. Die Verbindungs löcher zwischen der Zylinderbohrung sowie der Ritzelge häusebohrung und den Hydraulikkanälen werden nachträglich gebohrt.Such a housing is known from DE 40 19 693 the. In this known housing, the cylinder is off an extruded profile formed by in addition to the Zy Linderbohrung two hydraulic channels parallel to the cylinder bore are formed. The extruded profile is on the the side facing the pinion valve housing as far as possible works that only the two hydraulic lines remain, which then towards the central axis of the valve pinion bent and with the latter by casting around in the adjacent cylindrical area of the complete Extruded profile are connected into it. The connection holes between the cylinder bore and the pinion housing bore and the hydraulic channels are retrofitted drilled.
Ein solches Gehäuse hat zwar keine außenliegenden ange schraubten Hydraulikleitungen, es ist aber sehr aufwendig in der Fertigung und damit teuer.Such a housing has no external screwed hydraulic lines, but it is very expensive in production and therefore expensive.
Aufgabe der Erfindung ist es, ein Gehäuse nach dem Ober begriff des Patentanspruches zu schaffen, das ohne außen angebrachte Hydraulikleitungen auskommt und gegenüber be kannten Ausführungen einfacher herstellbar ist.The object of the invention is a housing according to the upper concept of claim to create that without outside attached hydraulic lines and be known versions is easier to manufacture.
Erfindungsgemäß wird diese Aufgabe durch die kennzeich nenden Merkmale des Patentanspruches gelöst.According to the invention, this object is characterized by nenden features of the claim solved.
Ein Ausführungsbeispiel der Erfindung ist nachstehend an hand einer Zeichnung näher beschrieben. Es zeigenAn embodiment of the invention is below hand described in more detail a drawing. Show it
Fig. 1 ein Gehäuse nach der Erfindung im Längsschnitt; Fig. 1 shows a housing according to the invention in longitudinal section;
Fig. 2 einen Schnitt entlang der Linie A-A in Fig. 1; FIG. 2 shows a section along the line AA in FIG. 1;
Fig. 3 einen Schnitt entlang der Linie B-B in Fig. 1. Fig. 3 is a section along the line BB in FIG. 1.
Ein Gehäuse 1 für ein hydraulisch unterstütztes Zahnstan genlenkgetriebe weist einen rohrförmigen Zylinder 2 zur Führung eines mit einer Zahnstange verbundenen Hydraulik kolbens, einen Raum 3 zur Führung der Zahnstange sowie ein Ritzelventilgehäuse 4 zur Lagerung des Zahnstangen ritzels und des mit ihm verbundenen Ventilschiebers auf. In einer Wandung 5 des Raumes 3 sind Hydraulikkanäle 6 zur Zuführung von Hydraulikflüssigkeit in den Zylinder 2 aus dem Ritzelventilgehäuse 4 vorgesehen. In der Wandung 7 ist eine weitere Hydraulikleitung 8 sowie eine Entlüf tungsleitung 9 für den am offenen Ende 10 des Raumes 3 im montierten Zustand angesetzten Faltenbalg vorgesehen. Die Hydraulikleitungen 6, 8 setzen sich durch die Wandung 11 des Ritzelventilgehäuses 4 fort und münden in dieses ein. Das Gehäuse 1 ist in einem Stück gegossen, wobei die Hy draulikkanäle 6, 8 sowie der Entlüftungskanal 9 beim Gie ßen durch Einlegen bzw. Einkleben einer verlorenen Form, die beim Gießvorgang vergast, mit hergestellt werden. Da mit die eingelegte Form für die Kanäle die richtige Lage während des Gießens beibehält, können zur Außenseite des Gehäuses 1 hin Abstützungen vorgesehen sein. Die dadurch entstehenden Öffnungen 12 werden bei der Montage des Lenkgetriebes verdeckelt. Bei diesem Gehäuse 1 müssen le diglich die inneren Wandungen des Zylinders 2 sowie des Ritzelventilgehäuses 4 und die äußeren Hydraulikanschlüs se 13 am Ritzelventilgehäuse 4 spanend bearbeitet werden.A housing 1 for a hydraulically assisted toothed rack gene steering gear has a tubular cylinder 2 for guiding a hydraulic piston connected to a toothed rack, a space 3 for guiding the toothed rack and a pinion valve housing 4 for mounting the toothed rack pinion and the valve slide connected to it. In a wall 5 of the room 3 , hydraulic channels 6 are provided for supplying hydraulic fluid into the cylinder 2 from the pinion valve housing 4 . In the wall 7 a further hydraulic line 8 and a ventilation line 9 is provided for the bellows attached to the open end 10 of the space 3 in the assembled state. The hydraulic lines 6 , 8 continue through the wall 11 of the pinion valve housing 4 and open into this. The housing 1 is cast in one piece, the Hy draulikkanäle 6 , 8 and the ventilation channel 9 during casting by inserting or gluing in a lost mold that is gasified during the casting process. Since the inserted shape for the channels maintains the correct position during casting, supports can be provided towards the outside of the housing 1 . The resulting openings 12 are capped during assembly of the steering gear. In this housing 1 le diglich the inner walls of the cylinder 2 and the pinion valve housing 4 and the outer Hydraulikanschlüs se 13 on the pinion valve housing 4 are machined.
Ein Lenkgetriebe mit einem solchen Gehäuse kann ohne au ßen angesetzte Leitungen auskommen. Das Gehäuse ist ein fach und damit kostengünstig herstellbar.A steering gear with such a housing can without au attached lines get along. The housing is a professional and therefore inexpensive to manufacture.
