Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device according to the preamble of claim 1.
Bei einer derartigen aus der
Zur Realisierung einer aktiven Federung gibt es verschiedene technologische Möglichkeiten. Aus o. g. Schrift sind integrale Dämpfer mit einem elektrischen Spiral- bzw. Linearmotor bekannt. Ferner sind Kombinationen aus Spiral- mit Linearmotor und Luftfederung bzw. Luftfederung mit Linearmotor und Spindelmotor mit Luftfederung, die jeweils parallel geschaltet sind, bekannt (

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangsgenannten Art zu schaffen, welche eine hohe Reaktionsfähigkeit auf ein breites Spektrum von Einfederungsbewegungen aufweist.The object of the invention is to provide a device of the type mentioned, which has a high responsiveness to a wide range of compression movements.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.This object is achieved by the features of claim 1.
Bei der Erfindung ist in Kombination mit dem zur Feder parallel geschalteten elektrischen Linearantrieb ein rotatorischer Elektroantrieb vorgesehen, mit welchem die obere Stützstelle, an welcher die Feder am Fahrzeugaufbau abgestützt ist, gegenüber dem Fahrzeugaufbau verstellbar ist und über welchen ferner die Feder am Fahrzeugaufbau abgestützt wird. Zwischen dem Radträger, an welchem die lasttragende Feder sich in einer unteren Stützstelle abstützt, und dem Fahrzeugaufbau sind der elektrische Linearantrieb und der rotatorische Elektroantrieb hintereinander geschaltet. Der rotatorische Elektroantrieb dient zur Verstellung der oberen Stützstelle bei niederfrequenten Bewegungen, während der elektrische Linearantrieb neben der Funktion des Dämpfers ferner in der Lage ist, als aktives Stellglied für schnelle Radbewegungen zu dienen. Durch die kombinierte Anwendung des elektrischen Linearantriebs und des rotatorischen Elektroantriebs ergibt sich eine Erweiterung des Spektrums der steuerbaren Einfederungsbewegungen. Mit Hilfe einer entsprechenden Regelung können die jeweiligen Bewegungsaufgaben auf den elektrischen Linearantrieb und den rotatorischen Elektroantrieb verteilt werden, wobei auch beide Antriebe bzw. Motore gleichzeitig eingesetzt werden können. Durch Regelung der Verteilung der Systemaufgaben kann dem jeweiligen Teilsystem, die gerade am besten zu beherrschende Teilaufgabe zugeordnet werden. Hierdurch ist es auch möglich den energetischen Einsatz zu minimieren, wobei nur eine Energieform für die beiden Antriebe erforderlich ist. In bevorzugter Weise können der Linearantrieb und der rotatorische Antrieb als Einheit hergestellt werden, die mit elektrischer Energie versorgt wird. Ferner läßt sich eine aktive Steuerung der Radbewegungen im voraus mit Hilfe einer Preview-Sensorik erreichen. Z. B. können die Radbewegungen an der Hinterachse in Abhängigkeit von den Radbewegungen an der Vorderachse mit Hilfe des elektrischen Linearantriebs, welcher als linearer Stellantrieb wirkt, im voraus realisiert werden.In the invention, a rotary electric drive is provided in combination with the electric linear drive parallel to the spring, with which the upper support point on which the spring is supported on the vehicle body, relative to the vehicle body is adjustable and via which also the spring is supported on the vehicle body. Between the wheel, on which the load-bearing spring is supported in a lower support point, and the vehicle body of the electric linear drive and the rotary electric drive are connected in series. The rotary electric drive is used to adjust the upper support point in low-frequency movements, while the electric linear drive in addition to the function of the damper is also able to serve as an active actuator for fast wheel movements. The combined use of the electric linear drive and the rotary electric drive results in an expansion of the spectrum of controllable compression movements. With the help of a corresponding control, the respective movement tasks can be distributed to the electric linear drive and the rotary electric drive, wherein both drives or motors can be used simultaneously. By regulating the distribution of the system tasks, the subsystem to be controlled can be assigned to the respective subsystem. This also makes it possible to minimize the energetic use, with only one form of energy for the two drives is required. Preferably, the linear drive and the rotary drive can be manufactured as a unit which is supplied with electrical energy. Furthermore, an active control of the wheel movements can be achieved in advance by means of a preview sensor. For example, the wheel movements on the rear axle in response to the wheel movements on the front axle by means of the electric linear drive, which acts as a linear actuator can be realized in advance.
Durch die Vielfalt der Funktionen können im wesentlichen alle Anforderungen, die an eine aktive Federung gestellt werden, wie Wankstabilisierung, variable Federungs- und Dämpfungseigenschaften, Niveauregulierung und dergleichen erfüllt werden. Außerdem erreicht man erheblich reduzierte Losbrechmomente durch Entfall des Dämpfers.Due to the variety of functions essentially all requirements that are placed on an active suspension, such as roll stabilization, variable suspension and damping properties, level control and the like can be met. In addition, significantly reduced breakaway torque is achieved by eliminating the damper.
Anhand der Figuren wird anhand von Ausführungsbeispielen die Erfindung noch näher erläutert. Es zeigt:Reference to the figures, the invention will be explained in more detail with reference to embodiments. It shows:
