Abstract
Description
Die Erfindung betrifft eine elektrische Servolenkung, insbesondere eine Hilfskraftlenkung für ein Fahrzeug, nach dem Oberbegriff des Anspruchs 1.The The invention relates to an electric power steering, in particular a Power steering system for a vehicle, according to the generic term of claim 1.
Die
Solche Servolenkungen können mit hydraulischen Wankstabilisatoren an einer Vorderachse und/oder an einer Hinterachse eines Fahrzeugs kombiniert werden um den Fahrkomfort und die Fahrsicherheit des Fahrzeugs aktiv zu verbessern.Such Power steering systems can be equipped with hydraulic roll stabilizers on a front axle and / or on a rear axle of a vehicle be combined to the ride comfort and driving safety of the Actively improve vehicle.
Hydraulische Wankstabilisatoren haben jedoch nachteilige Energiebilanzen und sind aufwändig in ihrer Ansteuerung.hydraulic However, roll stabilizers have disadvantageous energy balances and are complex in their control.
Die
Der Erfindung liegt die Aufgabe zugrunde, eine kompakt bauende elektrische Zahnstangen-Servolenkung anzugeben.Of the Invention is based on the object, a compact electrical construction Specify rack-and-pinion power steering.
Die Aufgabe wird mit einer elektrischen Servolenkung mit den Merkmalen des Anspruchs 1 gelöst.The Task is with an electric power steering with the features of claim 1.
Dadurch dass ein elektrischer Wankstabilisator dem Gestell, welches das axial verlagerbare Bauteil aufnimmt so zugeordnet ist, dass vorzugsweise der elektrische Wankstabilisator einen axialen Versatz zu dem Servomotor hat, lassen sich die spezifizierten Abstände zwischen der Drehachse des Wankstabilisators bzw. seiner Welle und dem axial verlagerbaren Bauteil und zu anderen benachbarten Bauteilen einhalten, um die nötigen Freiheitsgrade für Verformungen und Betriebslasten zu gewährleisten.Thereby that an electric roll stabilizer the frame, which the receiving axially displaceable component is assigned so that preferably the electric roll stabilizer an axial offset to the servomotor has, the specified distances between the Rotary axis of the roll stabilizer or its shaft and the axially displaceable Component and other adjacent components comply with the necessary degrees of freedom for deformations and operating loads to ensure.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
In einem besonders bevorzugten Ausführungsbeispiel ist der elektrische Wankstabilisator etwa achsparallel oder genau achsparallel zu der Servolenkung angeordnet. Es kann auch zweckmäßig sein, den elektrischen Wankstabilisator achsparallel zu dem als Lenkgetriebegehäuse gebildeten Gestell anzuordnen und in einem Vorderachskörper oder Hinterachskörper zu integrieren.In a particularly preferred embodiment is the electric roll stabilizer approximately parallel to the axis or exactly parallel to the axis arranged to the power steering. It may also be appropriate be, the electric roll stabilizer axis parallel to the as To arrange the steering gear housing formed frame and in a Vorderachskörper or Hinterachskörper too integrate.
Es kann zweckmäßig sein, die axiale Länge des Servomotors mit der axialen Länge des elektrischen Wankstabilisators zu überschneiden oder mit Abstand zueinander an der Baueinheit aus Servolenkung und elektrischem Wankstabilisator zu positionieren, sodaß beispielsweise ein radialer Abstand von Servomotor und elektrischem Wankstabilisator verringert werden kann.It may be appropriate, the axial length of the Servomotor with the axial length of the electric roll stabilizer to overlap or spaced apart on the unit from power steering and electric roll stabilizer to position so for example, a radial distance from servomotor and electric roll stabilizer can be reduced.
Um insbesondere den Achsabstand der Zahnstange oder des axial verlagerbaren Bauteiles zur Achse des elektrischen Wankstabilisators und dessen Welle so zu spezifizieren, dass beide Systeme innerhalb eines Vorderachsträgers ihre Funktion erfüllen, indem eine Verdrehbewegung mit überlagerter Biegebewegung der Welle des elektrischen Wankstabilisators gewährleistet ist und die Anordnung der Servomotoren der elektrischen Servolenkung und des elektrischen Wankstabilisators so getroffen werden kann, dass die Wärmeabfuhr auch der angegliederten Steuergeräte gewährleistet ist, sind bestimmte radiale Mindestabstände der einzelnen betreffenden Störkonturen der genannten Bauteile einzuhalten.Around in particular the center distance of the rack or the axially displaceable Component to the axis of the electric roll stabilizer and its Wave to specify that both systems are within a front axle fulfill their function by a twisting motion with superimposed Ensures bending movement of the shaft of the electric roll stabilizer is and the arrangement of servomotors of the electric power steering and the electric roll stabilizer can be made so that the heat dissipation also the affiliated control units is guaranteed, are certain radial minimum distances to comply with the individual relevant Störkonturen said components.
Es ist zweckmäßig, dass bei einem axialen Abstand von weniger als 2 mm zwischen der Störkontur der Antriebseinheit des elektrischen Wankstabilisators ein radialer Mindestabstand der Störkontur des Servomotors der elektrischen Servolenkung zu dem elektrischen Wankstabilisator des Lenkgetriebegehäuses zu dem Gehäuse des elektrischen Wankstabilisators von mindestens 2 mm eingehalten wird.It is appropriate that at an axial distance less than 2 mm between the interference contour of the drive unit of the electric roll stabilizer a radial minimum distance of the Interference contour of the servomotor of the electric power steering to the electric roll stabilizer of the steering gear housing to the housing of the electric roll stabilizer of at least 2 mm is maintained.
Es ist auch zweckmäßig, dass bei einem axialen Abstand von mehr als 2 mm zwischen dem Servomotor und dem elektrischen Wankstabilisator ein radialer Mindestabstand zwischen einer Störkontur der Welle des elektrischen Wankstabilisators und dem Lenkgetriebegehäuse, sowie zwischen einer Störkontur des elektrischen Wankstabilisators und dem Servomotor der elektrischen Servolenkung ein radialer Mindestabstand von mehr als 2 mm eingehalten wird.It is also appropriate that at an axial distance of more than 2 mm between the servo motor and the electric roll stabilizer a Radial minimum distance between an interference contour of the shaft of the electric roll stabilizer and the steering gear housing, and between a disturbing contour of the electric roll stabilizer and the servomotor of the electric power steering a minimum radial distance of more than 2 mm is maintained.
Ferner ist es zweckmäßig, dass bei einem axialen Abstand von mehr als 2 mm zwischen dem elektrischen Wankstabilisator und dem Lenkgetriebegehäuse ein radialer Abstand zwischen der Störkontur des Lenkgetriebegehäuses und dem elektrischen Wankstabilisator sowie zwischen einer Störkontur des Lenkgetriebes zu der Störkontur der Stabilisatorwelle von mehr als 2 mm gewählt ist.Further it is expedient that at an axial distance of more than 2 mm between the electric roll stabilizer and the steering gear housing, a radial distance between the Interference contour of the steering gear housing and the electric roll stabilizer as well as between an interference contour of the steering gear to the Interference contour of the stabilizer shaft of more than 2 mm selected is.
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.

Der
elektrische Wankstabilisator
Es wird eine kompakte Bauweise des elektrischen Wankstabilisators dadurch erreicht, da der Motor dessen klein bauen kann. Im Wankfall des Fahrzeugs wird durch den Wankstabilisator ein Gegenmoment aufgebracht, welches den Querkräften des Fahrzeugs entgegenwirkt.It becomes a compact design of the electric roll stabilizer thereby achieved because the engine can build its small. In the fall of the Vehicle is applied by the roll stabilizer a counter-moment, which counteracts the lateral forces of the vehicle.
