Description

Die Erfindung bezieht sich auf eine Hilfskraftlenküng für Kraftfahrzeuge, bei der in das Gestänge -zwischen dem Lenkrad und,den Rädern ein pneumatisch oder hydraulisch beaufschlagbarer Kolben einbebaut ist, der formschlüssig mit den Rädern verlbun@den ist und dessen Beaufschlagung durch ein vom Lenkrad verstellbares Steuerglied zum Regeln -der Druckmittelströme erfolgt.The invention relates to a power steering for motor vehicles, when in the linkage -between the steering wheel and, the wheels a pneumatic or hydraulically actuated piston is built in, which is form-fitting with the wheels is verlbun @ den and its application by a control member adjustable from the steering wheel to regulate the pressure medium flows.

Es ist bekannt, solche Hilfskraftlemkungen in der Weise auszubauen, daß das Fahrzeug beim Versagen der Hilfskraft noch mit Handkraft gelenkt werden kann.It is known to develop such auxiliary power training in such a way that that the vehicle can still be steered manually if the assistant fails can.

Das Ziel oder Erfindung ist es, eine möglichst einfache Bauart zu schaffen-, (bei der zudem sämtliche für die Hilfskraftlenkung wichtigen Teile eng zusammengebaut sind. Erfindungsgemäß ist diese der Erfindung zugrunde :liegende Auhgabe -lösbar, wenn die Hauptteile der Hilf.skraftlenkung so angeordnet werden, daß das Steuerglied und der Kolben einander umfassen; ferner sind in diesem Fall :dem Steuerglied und dem Kolben Anschläge zuzuordnen, die (beim Versagen der Hilfskraft die unmittelbare Mitnahme des Kolbens durch das Steuerglied (bewirken.The aim or invention is to have a construction that is as simple as possible create-, (in which all parts important for the power steering are tight are assembled. According to the invention, this is the basis of the invention: Issue -solvable if the main parts of the power steering system are arranged in such a way that the control member and the piston encompass one another; furthermore are in this case : assign stops to the control element and the piston which (if the auxiliary power fails the direct entrainment of the piston by the control element (cause.

Inder Zeichnung ist ein Ausführungsbeispiel im Ouerschnitt .schematisch dargestellt. Die Abbildung zeigt eine Anordnung, bei der das Steuerglied außen und der Kolben innen angeordnet sind: Das Lenkrad z ist über das Lenkstockgetriebe 2 und das Gestängeteil 3 mit Odem ringförmigen Steuerglied q. verbunden. Anden in den @Gehäuseteilen 5 und 6 :geführten Kolben 7 ist Idas zu den Rädern führende Lenkgestänge angeschlossen.In the drawing, an exemplary embodiment is shown schematically in cross-section shown. The figure shows an arrangement in which the control member outside and the pistons are arranged on the inside: the steering wheel z is via the steering column gear 2 and the rod part 3 with Odem annular control member q. tied together. Andes in the @ housing parts 5 and 6: guided piston 7 is Idas steering linkage leading to the wheels connected.

Die Pumpe 8 fördert das Druckmittel im Kreislauf vom Vorratsbehälter g durch das Kanalsystem zurick zum Vorratsbehälter. Das Steuergliedq. kann sich relativ zum Kolben? zwischen den Anschlägen 7a und 7b verschieben. Das .axiale Spiel a, b zwischen -den Anschlägen und dem den Kolben umfassenden ringförmigen Steuerglied q. ist so groß, daß ibei einer Verstellung des Lenkrades aus einer Ruhestellung heraus dann eine mechanische Mitnahme des Kolbens nicht erfolgt, wenn,die Hilfskraft voll ist. Das in beiden Hubräumen zo, rr der Gehäuseteile befindliche Druckmittel bremst die von Iden Rädern kommen-.den Stöße ab, so daß ein Flattern des Kolbens 7 nicht möglich ist. Fällt dagegen das Hilfskraftsystem aus, dann ist eine Notlenkung von Hand noch möglich. Das Vorhandensein des axialen Spiels cä, b wird jedoch den Kraft£ährzeugfahrer davon abhalten, größere Strecken mit der Notlenkung zu fahren; er muß vor Antreten einer Fahrt die Lenkvorrichtung in Aden alten Stand bringen lassen.The pump 8 conveys the pressure medium in the circuit from the reservoir g through the channel system back to the reservoir. The control member q. can be relative to the piston? move between the stops 7a and 7b. The axial play a, b between the stops and the ring-shaped control member comprising the piston q. is so large that when the steering wheel is adjusted from a rest position, the piston is not mechanically entrained when the auxiliary power is full. The pressure medium located in both displacements zo, rr of the housing parts brakes the impacts coming from the wheels, so that the piston 7 cannot flutter. If, on the other hand, the auxiliary power system fails, manual emergency steering is still possible. The presence of the axial play cä, b will, however, prevent the driver from driving longer distances with the emergency steering; he must have the steering device in Aden restored to its old status before starting a journey.
