Derartige Systeme bieten den grundsätzlichen Vorteil, dass sie zumindest hinsichtlich der Regelanordnung sowie der zugehörigen Sensorik ohne konstruktive Abänderungen für unterschiedlichste Fahrzeuge geeignet sind. Durch entsprechende Programmierung kann einerseits praktisch jedes Übersetzungsverhältnis zwischen einem Stellhub an der Lenkhandhabe und einem Stellhub beispielsweise eines durch den Aktuator axial verschobenen Bauteils, wie einer Zahnstange oder Spindel und damit verbundenen Rädern verwirklicht werden. Solche Lenksysteme zeichnen sich ferner durch hohe Flexibilität beim Einbau in Motorräume von Kraftfahrzeugen in Bezug auf den Bauraumbedarf aus. Darüber hinaus besteht die Möglichkeit, die Regelanordnung mit zusätzlichen Sensoren zu verbinden um Fahrtparameter selbstätig zu berücksichtigen oder auszuregeln.For future motor vehicles are being developed steering systems which work steer-by-wire according to the concept. Such steering systems are characterized by the fact that in normal operation with a steering handle on a constantly checking for correct function Electronic control system Actuators for steering angle adjustment steers steerable wheels. Such systems offer the fundamental advantage that they at least in terms the control arrangement and the associated sensors without constructive modifications for the most diverse Vehicles are suitable. By appropriate programming can on the one hand practically every gear ratio between a control stroke on the steering handle and a control stroke, for example a axially displaced by the actuator component, such as a Rack or spindle and associated wheels realized become. Such steering systems are also characterized by high flexibility when installing in engine compartments of motor vehicles in relation on the space requirement. In addition, there is the possibility to connect the control arrangement with additional sensors to take into account driving parameters selbstätig or correct.

Das axial verlagerbare Bauteil in der Führungsbuchse kann durch eine geeignete Wahl des Querschnittsprofils der Führungsbuchse in einer Linienführung geführt sein. Dazu eignet sich ein Polygonprofil oder die Ausbildung der Führungsbuchse als Rollenlager. Durchmessertoleranzen des vorzugsweise als Zahnstange gebildeten axial verlagerbaren Bauteiles lassen sich hierdurch in gewissen Bereichen kompensieren.The axially displaceable component in the guide bush can through a suitable choice of the cross-sectional profile of the guide bushing be guided in a line. Suitable for this a polygon profile or the formation of the guide bush as Roller bearings. Diameter tolerances of preferably as a rack formed axially displaceable components can be characterized in compensate for certain areas.

Bevorzugt hat die erste und/oder zweite Führungsbuchse ein Verhältnis ihres größten Führungsdurchmessers zur Breite der Führungsbuchse zwischen 0,3 und 3,5. Ferner ist bevorzugt ein Verhältnis der Wandstärke der ersten und/oder zweiten Führungsbuchse zu ihrem Außendurchmesser von 0,01 bis 0,3 gewählt, um ein Klemmen der Zahnstange bei Biegung zu vermeiden. Die Führungsbuchsen sind bevorzugt einteilig gebildet und haben eine Axialanschlagsfunktion für die Zahnstange.Prefers the first and / or second guide bush has a relationship their largest guide diameter to Width of the guide bush between 0.3 and 3.5. Further is preferred a ratio of the wall thickness of first and / or second guide bush to its outer diameter from 0.01 to 0.3 chosen to clamp the rack to avoid bending. The guide bushes are preferred formed integrally and have an axial stop function for the rack.
Es kann zweckmäßig sein, die Führungsbuchse in dem Gehäusedeckel und/oder in dem Getriebegehäuse radialelastisch zu lagern oder mit Spiel in dem Gehäusedeckel oder dem Getriebegehäuse zu lagern, wobei unter Last die Führungsbuchse dann an dem Gehäusedeckel oder dem Getriebegehäuse anliegt.It may be appropriate, the guide bush in the housing cover and / or in the transmission housing Store radially elastic or with play in the housing cover or to store the gear housing, under load the Guide bush then on the housing cover or rests against the gear housing.
Die Führungsbuchsen lassen sich auch radial positionieren und fixieren, wobei insbesondere eine Einrichtung zur Einstellung und Feststellung der radialen Position in dem Gehäusedeckel oder dem Getriebegehäuse angewandt ist, die beispielsweise aus drei Stellschrauben mit tangentialem Abstand relativ zu der Mantelfläche der Führungsbuchse die radiale Position der Führungsbuchsen in dem Gehäusedeckel bestimmen können.The Guide bushes can also be positioned radially and fix, in particular a device for setting and Determining the radial position in the housing cover or the transmission housing is applied, for example three adjusting screws with tangential distance relative to the lateral surface the guide bush the radial position of the guide bushes can determine in the housing cover.
Vorzugsweise sind die Führungsflächen der ersten und/oder zweiten Führungsbuchse so geformt, dass sie ein von der Kreisform so abweichendes Querschnittsprofil haben, dass sie eine Verdrehsicherung des axial verlagerbaren Bauteils bewirken. Zudem kann das Querschnittsprofil der äußeren oder inneren Mantelflächen der Führungsbuchsen so gestaltet sein, dass eine linienförmige Anlage des axial verlagerbaren Bauteils an der jeweiligen Führungsbuchse oder eine linienförmige Anlage der Führungsbuchse an dem Gehäusedeckel oder Getriebegehäuse bewirkt ist.Preferably are the guide surfaces of the first and / or second Guide bush shaped so that it is one of the circular shape so deviating cross-sectional profile that they have a rotation cause the axially displaceable component. In addition, the cross-sectional profile the outer or inner lateral surfaces the guide bushes be designed so that a linear Installation of the axially displaceable component on the respective guide bush or a linear arrangement of the guide bush effected on the housing cover or gear housing is.
Die äußeren und/oder inneren Mantelflächen der Führungsbuchsen können auch ballig gebildet sein, sodaß eine Schiefstellung des axial verlagerbaren Bauteils oder der Zahnstange bei Biegung und ein Folgen der Führungsbuchse der Biegelinie der Zahnstange ermöglicht ist. Die Führungsbuchsen sind bevorzugt dauergeschmiert mit Schmiernuten oder Schmiertaschen. Als Werkstoff für die Führungsbuchsen eignet sich ein Kunststoff, wie Polyamide, Polyoxymethylen, Polyphenylenether, Polyethylenterephtalat und Polybutylenterephtalat, wobei Verbundwerkstoffe aus Metall und Kunststoff oder geeignete Lagermetalle angewandt sein können.The outer ones and / or inner circumferential surfaces of the guide bushes can also be formed spherically, so that a misalignment the axially displaceable component or the rack when bent and following the guide bush of the bending line of the rack is possible. The guide bushes are preferred lubricated with lubrication grooves or lubrication pockets.
