Abstract
Description
Die Erfindung betrifft eine Hilfskraftlenkung für ein Fahrzeug mit einem Servomotor in einem Servomotorgehäuse, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a power steering system for a vehicle with a servo motor in a servomotor housing, after the Preamble of claim 1.
Hilfskraftlenkungen
für Kraftfahrzeuge, die insbesondere als Zahnstangenlenkungen
ausgebildet sind, sind bekannt. Ein Aktuator aus einem Servomotor
und einem nachgelagerten Getriebezug stellt hierbei eine Lenkhilfskraft
auf ein Lenkgetriebe bereit. Die Lenkhilfskraft kann auf verschiedene
Weise erzeugt und auf verschiedene Weise in das Lenkgetriebe eingegeben
werden. So beschreibt die
Die
Der Erfindung liegt die Aufgabe zugrunde, eine Hilfskraftlenkung anzugeben, die auf einfache Weise, rasch zu montieren ist.Of the Invention is the object of specifying a power steering system, which is easy to assemble quickly.
Die Aufgabe wird mit einer Hilfskraftlenkung mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a power steering system with the features of the claim 1 solved.
Dadurch dass die Schraubverbindung zur Festlegung des den Getriebezug aufnehmend Gehäuseteils und/oder des Servomotorgehäuses an dem Lenkgetriebegehäuse mit einer minimierten Anzahl gleichlanger Schrauben oder höchstens zwei unterschiedliche Längen aufweisenden Schrauben gebildet wird, ist die Montage der Hilfskraftlenkung deutlich vereinfacht und beschleunigt im Vergleich zum Stand der Technik durchführbar.Thereby that the threaded connection for fixing the gear train receiving Housing part and / or the servomotor housing on the steering gear housing with a minimized number of screws of the same length or at most formed two different lengths having screws is, the installation of the power steering system is significantly simplified and accelerated compared to the prior art feasible.
Der Gehäusedeckel zur Aufnahme des Getriebezugs kann dabei mit einer einzigen Schraube an dem Lenkgetriebegehäuse festgelegt sein. Das Servomotorgehäuse ist bevorzugt nur mit zwei Schrauben an dem Lenkgetriebegehäuse festgelegt. Alle dazu verwendeten Schrauben sind bevorzugt zur Festlegung des Servomotorgehäuses und des Gehäusedeckels an dem Lenkgetriebegehäuse gleichzeitig herangezogen und von einer Seite aus montiert.Of the Housing cover for receiving the gear train can thereby with a single screw on the steering box be set. The servo motor housing is preferred only fixed to the steering box with two screws. All screws used for this purpose are preferred for fixing the servo motor housing and the housing cover on the steering gear housing at the same time used and mounted from one side.
Um gleichlange Schrauben verwenden zu können ist es zweckmäßig, die Summe der axialen Längen oder die Summe der Gehäusetiefen im Bereich der Schraubenbohrungen exakt oder annähernd gleichlang zu gestalten.Around it is expedient to use screws of the same length the sum of the axial lengths or the sum of the housing depths in the area of screw holes exactly or approximately to make it the same.
Bevorzugt sind die Schraubverbindungen als Durchsteckschraubverbindungen oder Aufschraubverbindungen gebildet.Prefers are the screw as Durchschraubschraubverbindungen or Screw connections formed.
Es ist zweckmäßig Zylinderschrauben mit Innensechskant zu verwenden. Bevorzugt ist die Hilfskraftlenkung als elektrische Hilfskraftlenkung mit einem Zugmittelgetriebe gebildet.It is appropriate cylinder head screws with hexagon socket to use. Preferably, the power steering system is electrical Power steering system formed with a traction mechanism.
Die Erfindung wird nun näher anhand eines Ausführungsbeispiels beschrieben und anhand der beiliegenden Zeichnung wiedergegeben.The Invention will now be closer with reference to an embodiment described and reproduced with reference to the accompanying drawings.
