Abstract
Description
Die Erfindung betrifft eine Lenkvorrichtung, insbesondere für ein Kraftfahrzeug, insbesondere nach dem Oberbegriff von Anspruch 1. The invention relates to a steering device, in particular for a motor vehicle, in particular according to the preamble of
Die Erfindung betrifft eine Lenkvorrichtung mit einem schwimmend angeordneten Zahnrad bzw. Ritzel. Das Zahnrad wird dabei von einer Lenkwelle mittels eines Lenkrads verdreht. Über das Ritzel wird eine Kolbenstange einer Kolben-Zylindereinheit axial verlagert, welche das Gewinde des Zahnrads kämt. Hierbei kommt es je nach Handmoment und Druck in den Zylindern der Kolben-Zylindereinheit zu einer Auslenkung des Ritzels um etwa +–1 mm, was durch die federnde Lagerung des Zahnrads erlaubt wird. Durch die sich dadurch ergebende Bewegung des Lagers wird ein Hydraulikventil über ein Verbindungselement angesteuert, welches den Druck in den Zylindern der Kolben-Zylindereinheit ansteuert. The invention relates to a steering device with a floating gear or pinion. The gear is thereby rotated by a steering shaft by means of a steering wheel. About the pinion, a piston rod of a piston-cylinder unit is axially displaced, which kämme the thread of the gear. Depending on the moment of hand and pressure in the cylinders of the piston-cylinder unit, this results in a deflection of the pinion about + -1 mm, which is permitted by the resilient mounting of the gearwheel. Due to the resulting movement of the bearing, a hydraulic valve is actuated via a connecting element, which controls the pressure in the cylinders of the piston-cylinder unit.
Auch sind hydraulisch betätigte Lenkvorrichtungen durch die
Diese Lenkvorrichtung ist rein passiv gesteuert. Um den Komfort und das Lenkverhalten zu verbessern ist ein aktiver Eingriff in das Lenkverhalten erwünscht. Dies können unter anderem eine Linearisierung der Lenkungskennlinie, eine geschwindigkeitsabhängige Lenkunterstützung oder eine Korrektur des Geradeauslaufs der Lenkung sein. This steering device is purely passive controlled. In order to improve the comfort and the steering behavior, an active intervention in the steering behavior is desired. These may include a linearization of the steering characteristic, a speed-dependent steering assistance or a correction of the straight-line steering.
Es ist die Aufgabe der vorliegenden Erfindung, eine Lenkvorrichtung der eingangs gennannten Gattung dahingehend zu verbessern, dass aktive Lenkfunktionen realisiert werden können. It is the object of the present invention to improve a steering device of the type mentioned in the introduction so that active steering functions can be realized.
Die Aufgabe wird mit den Merkmalen von Anspruch 1 gelöst. The object is achieved with the features of
Ein Ausführungsbeispiel der Erfindung betrifft eine Lenkvorrichtung mit einem in einem Hydraulikzylinder angeordneten Hydraulikkolben, wobei der Hydraulikkolben mittels einer Kolbenstange antreibbar axial verlagerbar ist, die Kolbenstange eine Verzahnung aufweist, die von einem Zahnrad gekämmt wird, das Zahnrad in einem Lager gehalten ist und von einem fahrerseitigen Bedienelement verdrehbar ist, wobei das Lager mittels eines Verbindungsmittels mit einem Hydraulikventil in Wirkverbindung steht, wobei eine Beaufschlagung oder Verschiebung des Lagers mittels eines Stellglieds erfolgt. Damit kann eine externe Ansteuerung des Lenkverhaltens zu der fahrerseitigen Einflussnahme realisiert werden. An embodiment of the invention relates to a steering device with a arranged in a hydraulic cylinder hydraulic piston, wherein the hydraulic piston by means of a piston rod drivable axially displaceable, the piston rod has a toothed, which is combed by a gear, the gear is held in a bearing and a driver side Operating element is rotatable, wherein the bearing is in operative connection by means of a connecting means with a hydraulic valve, wherein a loading or displacement of the bearing takes place by means of an actuator. Thus, an external control of the steering behavior to the driver-side influence can be realized.
Dabei ist es zweckmäßig, wenn das Stellglied zwischen dem Verbindungselement und einem Schieber, wie Kolben, des Hydraulikventils angeordnet ist. So kann direkten Einfluss auf die Verstellmechanik genommen werden, um eine externe Beeinflussung vorzunehmen. It is expedient if the actuator between the connecting element and a slider, such as piston, of the hydraulic valve is arranged. Thus, direct influence on the adjustment mechanism can be taken to make an external influence.
Auch ist es zweckmäßig, wenn das Stellglied zwischen einem Gehäuse des Hydraulikventils und einer Lagerung des Hydraulikventils angeordnet ist. Da die Lage des Hydraulikventils relativ zu der Lagerung des Hydraulikventils Einfluss auf die Verstellmechanik nimmt, kann auch damit Einfluss durch eine externe Ansteuerung genommen werden. It is also expedient if the actuator is arranged between a housing of the hydraulic valve and a bearing of the hydraulic valve. Since the position of the hydraulic valve relative to the bearing of the hydraulic valve influences the adjustment mechanism, this can also be influenced by an external control.
Erfindungsgemäß ist es vorteilhaft, wenn das Stellglied elektromechanisch und/oder hydromechanisch ansteuerbar ist. Dabei ist das Stellglied ein elektromotorisch oder ein hydraulisch betätigbares Stellglied. According to the invention it is advantageous if the actuator is electromechanically and / or hydromechanically controllable. In this case, the actuator is an electric motor or a hydraulically actuated actuator.
