Abstract
Die Erfindung bezieht sich auf ein Hilfskraftlenksystem für eine lenkbare Achse (2) eines Fahrzeugs mit einem Arbeitszylinder (4), dessen Hydraulikkreis steuerunabhängig vom Hydaulikkreis (31) des Lenkgetriebes ist und mittels einer Steuereinheit (25, 26) und eines Stellglieds (20) steuerbar ist, wobei Mittel zur Erkennung einer Betriebsstörung des Arbeitszylinders (4) und/oder eines Arbeitszylinderhydraulikkreises (33) und Mittel zur Aufrechterhaltung eines Notlaufbetriebs im Falle einer erkannten Betriebsstörung vorgesehen sind.The invention relates to a power steering system for a steerable axle (2) of a vehicle with a working cylinder (4) whose hydraulic circuit is independent of the hydaulic circuit (31) of the steering gear and controllable by means of a control unit (25, 26) and an actuator (20) wherein means are provided for detecting a malfunction of the working cylinder (4) and / or a working cylinder hydraulic circuit (33) and means for maintaining an emergency operation in the event of a detected malfunction.
Description
Die Erfindung bezieht sich auf ein auf eine Vor- oder Nachlaufachse wirkendes Hilfskraftlenksystem eines Fahrzeugs, insbesondere eines Lastkraftwagens oder einer lenkbaren Achse eines Anhängers oder Aufliegers oder einer lenkbaren Achse eines Fahrzeugwagens, insbesondere eines zwei- oder mehrgliedrigen Gelenkomnibusses.The The invention relates to a on a leading or trailing axle acting power steering system of a vehicle, in particular a Truck or a steerable axle of a trailer or Semi-trailer or a steerable axle of a vehicle, in particular of a two or more limb articulated bus.
In
der
Aufgabe vorliegender Erfindung ist es, ein Hilfskraftlenksystem anzugeben, das sich auf eine Vor- oder Nachlaufachse eines Kraftfahrzeugs oder einer lenkbaren Achse eines Fahrzeugs, beispielsweise einem Anhänger oder Auflieger oder eines Fahrzeugwagens eines zwei- oder mehrgliedrigen Gelenkomnibusses, bezieht und in einfacher Weise die Aufrechterhaltung eines Notlaufbetriebs im Fehlerfall ermöglicht.task The present invention is to provide a power steering system, which refers to a leading or trailing axle of a motor vehicle or a steerable axle of a vehicle, such as a trailer or Semi-trailer or a vehicle of a two or more members Articulated bus, relates and maintenance in a simple way an emergency operation in case of failure allows.
Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.These The object is achieved with the characterizing features of claim 1. advantageous Embodiments of the invention are specified in the subclaims.
Die Erfindung geht von einer Hilfskraftlenkung für eine lenkbare Achse eines Fahrzeugs mit einem Arbeitszylinder, dessen Hydraulikkreis steuerunabhängig vom Hydraulikkreis des Lenkgetriebes ist und mittels einer Steuereinheit und einem Stellglied steuerbar ist, aus.The Invention is based on a power steering system for a steerable axle Vehicle with a working cylinder whose hydraulic circuit is independent of the tax Hydraulic circuit of the steering gear is and by means of a control unit and an actuator is controllable from.
Dadurch dass Mittel zur Erkennung einer Betriebsstörung des Arbeitszylinders und/oder eines Arbeitszylinderhydraulikkreises und Mittel zur Aufrechterhaltung eines Notlaufbetriebs im Falle einer erkannten Betriebsstörung vorgesehen sind, wird in vorteilhafter Weise die Erkennung einer Fehlfunktion der Hinterachslenkung erreicht und die Sicherstellung eines für den Notlaufbetrieb der Hinterachslenkung definiertes Lenkverhalten gewährleistet.Thereby that means for detecting a malfunction of the working cylinder and / or a power cylinder hydraulic circuit and means for maintaining an emergency operation in the event of a detected malfunction intended are, advantageously, the detection of a malfunction the rear axle steering achieved and ensuring one for the emergency operation the rear axle steering ensures defined steering behavior.
In einer bevorzugten Ausführungsform ist vorgesehen, zur Aufrechterhaltung eines Notlaufbetriebs einen zu- und abschaltbaren hydraulisch oder pneumatisch wirkenden Zentrierzylinder einzusetzen, der mittels einer Zwangskopplung mit dem Arbeitszylinder und den gelenkten Rädern mechanisch verbunden ist.In a preferred embodiment is provided to maintain a runflat one can be switched on and off hydraulically or pneumatically acting centering use, by means of a forced coupling with the working cylinder and the steered wheels mechanically connected.
In einer weiteren Ausführungsform ist vorgesehen, dass zur Erkennung einer Betriebsstörung des Arbeitszylinders oder des Arbeitszylinderhydraulikkreises ein Lineargeber oder ein im Arbeitszylinderhydraulikkreis befindlicher Drucksensor sind. Der Lineargeber wird dabei unmittelbar am Arbeitszylinder angebracht und erfasst berührungslos die Stellung des Kolbens im Arbeitszylinder. Das Ausgangssignal kann zur Plausibilisierung und/oder Regelzwecken einer Steuereinheit zugeführt werden.In a further embodiment is provided that for detecting a malfunction of the Working cylinder or working cylinder hydraulic circuit a linear encoder or a pressure sensor located in the working cylinder hydraulic circuit are. The linear encoder is directly on the working cylinder attached and recorded contactless the position of the piston in the working cylinder. The output signal can for plausibility and / or control purposes of a control unit supplied become.
In einer weiteren Ausführungsform ist vorgesehen, dass der Zentrierzylinder, redundant vorhanden ist. Dies erhöht die Betriebssicherheit zusätzlich.In a further embodiment is provided that the centering, is redundant. This elevated the operational safety additionally.
In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, einen bidirektionalen Austausch von Daten, insbesondere Informationen bezüglich den Stati des Hilfskraftlenksystems, den Druckverhältnissen im Arbeitszylinderhydraulikkreis und den mittels eines Drucksensors gemessenen Druckverhältnissen im Zentrierzylinderhydraulikkreis und Informationen, geeignet zur Beschreibung der Ortslage des im Arbeitszylinder befindlichen Kolbens und einer Information zur Beschreibung der Radstellung der Räder zwischen den Steuereinheiten, zu ermöglichen.In A further embodiment of the invention is provided, a bidirectional exchange of data, in particular information in terms of the status of the power steering system, the pressure ratios in the working cylinder hydraulic circuit and by means of a pressure sensor measured pressure conditions in Zentrierzylinderhydraulikkreis and information, suitable for Description of the location of the piston located in the working cylinder and information describing the wheel position of the wheels between the control units.
Eine weitere Ausführungsform sieht vor, den Arbeitszylinder und Zentrierzylinder in einer Baugruppe oder Baueinheit zu integrieren. Dies hat den Vorteil, dass Sensoren vorteilhaft integriert werden können und der Bauraum verkleinert wird, zusätzlich können dadurch die Zuleitungslängen von Hydraulik- oder Pneumatikleitungen verkürzt werden.A another embodiment provides the working cylinder and centering in an assembly or Integrate unit. This has the advantage that sensors are advantageous can be integrated and the space is reduced, in addition, thereby the supply line lengths of Hydraulic or pneumatic lines are shortened.
Bevorzugt wird das Hilfskraftlenksystem in Fahrzeugwagen, die mit einem Knickgelenk miteinander verbunden sind, beispielsweise in einem letzten Fahrzeugwagen eines mehrgelenkigen Omnibusses, eingesetzt.Preference is given to the power steering system in vehicle cars, with an articulated joint with each other are connected, for example, in a last vehicle of a multi-articulated bus, used.
