Abstract
Description
Die Erfindung betrifft eine Überlagerungslenkung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a superposition steering according to the preamble of Claim 1.
Die
Die Drehbewegung des Ausgangsglieds des Überlagerungsgetriebes wird von einem Sensor gemessen und von einer Steuerungs- und/oder Regelungseinrichtung erfasst. Die Steuerungs- und/oder Regelungseinrichtung steuert wiederum den Servomotor.The Rotary movement of the output member of the superposition gear is measured by a sensor and by a control and / or Control device detected. The control and / or regulating device in turn controls the servomotor.
Die bekannten Überlagerungslenkungen weisen Sensoren zur Messung des Summenwinkels auf, die auch zur Darstellung einer absoluten Mittellage des Ausgangsglieds verwendet werden können, die aber teuer sind und einen nicht minimierten Bauraumbedarf haben.The known overlay steering systems have sensors for measurement of the sum angle, which also represents an absolute Central position of the output member can be used, the but are expensive and have a non-minimized space requirement.
Der Erfindung liegt die Aufgabe zugrunde, eine kleinbauende, kostengünstige Überlagerungslenkung zu schaffen.Of the Invention is based on the object, a small-sized, cost-effective superposition steering to accomplish.
Die Aufgabe wird mit einer Überlagerungslenkung mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a superposition steering with the features of claim 1.
Dadurch dass eine Steuerungs- und/oder Regelungseinrichtung den Indeximpuls eines einfachen Indexsensors bei Überfahren einer an dem Ausgangsglied oder einem damit drehfest verbundenen Bauteil mit Impulsen der beiden Radrehzahlsensoren die eine annähernde Geradeausfahrt des Fahrzeugs anzeigen können, plausibilisiert und verknüpft, ist eine einfache, bauraumsparende Sensorik gegeben, die eine Mittelstellung des Ausgangsglieds erfassen kann.Thereby a control and / or regulating device controls the index pulse a simple index sensor when passing one on the Output member or a rotatably connected component with Impulses of the two Radrehzahlsensoren the approximate Can indicate straight-line driving of the vehicle, checked for plausibility and linked, is a simple, space-saving sensors given, which can detect a center position of the output member.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
In einem besonders bevorzugten Ausführungsbeispiel der Überlagerungslenkung ist der Indexsensor mit einem Rotorlagesensor für eine Servomotorwelle des Überlagerungsgetriebes oder für dessen zweites Getriebeausgangsglied in einem einzigen Gehäuse zusammengefasst, was kostengünstig und bauraumsparend ist.In a particularly preferred embodiment of the superposition steering is the index sensor with a rotor position sensor for a Servomotor shaft of the superposition gear or for its second transmission output member in a single housing summarized, which is inexpensive and space-saving.
Der die Mittellage des Ausgangsgliedes abtastende Indexsensor ist mit seiner Stromversorgung und vorzugsweise mit seinen Signalleitungen mit dem Rotorlagesensor örtlich eng verbunden. Vorzugsweise wird ein Kabelbaum verwendet.Of the the center position of the output member scanning index sensor is with its power supply and preferably with its signal lines locally closely connected to the rotor position sensor. Preferably a wiring harness is used.
In einem bevorzugten Ausführungsbeispiel mündet der Kabelbaum in einer gemeinsamen Kupplung oder Stecker an der Peripherie des Überlagerungsgetriebes. Die Index-Marke ist bevorzugt auf einer Außenfläche eines zylindrischen Stürzringes angeordnet, der Teil eines Wellgetriebes ist, das das Überlagerungsgetriebe bildet. Eine kleinbauende Lösung der Überlagerungslenkung sieht vor, dass der Index-Sensor in dem Stecker des Rotorlagesensors selbst angeordnet ist, sodaß eine einfachste Montage und Justage an dem Überlagerungsgetriebe zusammen mit dem Stecker möglich ist.In a preferred embodiment of the opens Wiring harness in a common coupling or connector on the periphery of the superposition gearbox. The index mark is preferred on an outer surface of a cylindrical Stürzringes arranged, which is part of a corrugated transmission, which is the superposition gearbox forms. A compact solution of the superposition steering provides that the index sensor in the connector of the rotor position sensor itself is arranged so that the simplest installation and adjustment at the superposition gear together with the plug possible is.
Die Index-Marke kann eine optische Marke in Form von Zähnen, Kerben, Lochungen und dergleichen sein, es kann auch zweckmäßig sein, solch eine Marke als feldverändernde Marke, die ein magnetisches oder elektromagnetisches Feld eines mit einem Hilfsfeld versehenen Sensors verändert, auszubilden. Es kann auch zweckmäßig sein, die Index-Marke als felderzeugende Marke, die induktiv ein elektromagnetisches Feld erzeugt oder ein Magnetfeld erzeugt, auszubilden. In einem bevorzugten, einfachen Ausführungsbeispiel ist die Index-Marke als Längsnut auf der Oberfläche des Ausgangsgliedes gebildet.The Index mark can be an optical mark in the form of teeth, Notches, perforations and the like, it may also be appropriate be such a brand as a field-changing brand, the one magnetic or electromagnetic field of one with an auxiliary field provided sensor changed, form. It can also be appropriate, the index mark as field-generating Brand that inductively generates or generates an electromagnetic field Magnetic field generated, form. In a preferred, simple Embodiment is the index mark as a longitudinal groove formed on the surface of the output member.
In Kombination mit dieser feldverändernden Index-Marke eignet sich als Index-Sensor ein Hallsensor mit magnetischem Hilfsfeld.In Combination with this field-changing index mark as index sensor a Hall sensor with magnetic auxiliary field.
