Description
Die Erfindung betrifft einen aktiven Stabilisator für ein Kraftfahrzeug nach dem Oberbegriff des Anspruchs 1.The invention relates to an active stabilizer for a motor vehicle according to the preamble of claim 1.
Es ist bereits ein aktiver Stabilisator für ein Kraftfahrzeug bekannt, der zwei Räder einer Fahrzeugachslinie koppelt und der aus einem dem einen Rad zugeordneten ersten Stabilisatorteil und aus einem dem anderen Rad zugeordneten zweiten Stabilisatorteil, sowie aus einem die Stabilisatorteile koppelnden Aktuator besteht. Der Aktuator steuert die Seitenneigung des Kraftfahrzeugs durch Verspannen der Stabilisatorteile gegeneinander. Jedes Stabilisatorteil erstreckt sich von einem dem Aktuator zugeordneten Anschluss zu einem dem Rad zugeordneten Anschluss. Einen solchen Stabilisator beschreibt die gattungsbildende
Bei Stabilisatoren mit eingebautem Aktuator ist die tordierbare wirksame Länge eingeschränkt gegenüber herkömmlichen Stabilisatoren ohne Aktuator. Die wirksame Torsionslänge setzt sich zusammen aus der Länge der beiden Stabilisatorteile in Fahrzeugquerrichtung. Durch diese Verkürzung der wirksamen Torsionslänge auf Grund des eingebauten Aktuators können sich die Dauerfestigkeitswerte des Stabilisators verschlechtern. Außerdem wird dadurch die Charakteristik des Kraftfahrzeugs beim Unterdrücken von Wankbewegungen verändert.In stabilizers with built-in actuator, the twistable effective length is limited compared to conventional stabilizers without an actuator. The effective torsion length is composed of the length of the two stabilizer parts in the vehicle transverse direction. This shortening of the effective torsional length due to the built-in actuator can degrade the fatigue strength values of the stabilizer. In addition, the characteristic of the motor vehicle is thereby changed in suppressing rolling movements.
Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden, indem die Federrate mindestens eines Stabilisatorteils, das sich von einem dem Aktuator zugeordneten Anschluss zu einem dem Rad zugeordneten Anschluss erstreckt, kleiner ist als eine minimal benötigte Federrate für ein derselben Belastung ausgesetztes Stabilisatorteil, das im Wesentlichen direkt von dem dem Aktuator zugeordneten Anschluss zu dem dem Rad zugeordneten Anschluss geführt ist.The object of the invention is to avoid these disadvantages, in that the spring rate of at least one stabilizer part extending from a connection assigned to the actuator to a connection assigned to the wheel is smaller than a minimum required spring rate for a stabilizer part exposed to the same load Substantially guided directly from the actuator associated with the connection to the connection assigned to the wheel.
Die Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved with the features of claim 1.
Nach der Erfindung ist ein aktiver Stabilisator für ein Kraftfahrzeug, der zwei Räder einer Fahrzeugachslinie koppelt und der aus einem dem einen Rad zugeordneten ersten Stabilisatorteil und aus einem dem anderen Rad zugeordneten zweiten Stabilisatorteil, sowie aus einem die Stabilisatorteile koppelnden Aktuator besteht, so gestaltet, dass die wirksame Länge des Stabilisators dadurch verlängert, dass jedes Stabilisatorteil am Aktuator vorbei geführt ist und an dem Anschluss mit dem Aktuator verbunden ist, der von dem dem Rad zugeordneten Anschluss weiter entfernt liegt. Das hat den Vorteil, dass die wirksame Torsionslänge auf einfache Weise verlängert ist und dass das Stabilisatorteil bei gleicher Belastung um einen größeren Weg ausgelenkt wird und somit die Unterdrückung der Wankbewegung weicher gestaltet werden und feiner abgestimmt werden kann. Die Lebensdauer des Stabilisators kann erhöht werden. Durch die Möglichkeit, Stabilisatoren mit kleinerem Durchmesser verwenden zu können, wird das Fahrzeuggewicht verringert und die Herstellkosten für den Stabilisator sind geringer. Außerdem ergeben sich größere Freiheiten für die Anordnung des Stabilisators im Fahrzeug.According to the invention, an active stabilizer for a motor vehicle which couples two wheels of a vehicle axle line and which consists of a first stabilizer part assigned to one wheel and a second stabilizer part assigned to the other wheel and of an actuator coupling the stabilizer parts is designed such that lengthens the effective length of the stabilizer by passing each stabilizer part past the actuator and being connected at the port to the actuator farther from the port associated with the wheel. This has the advantage that the effective torsion length is easily extended and that the stabilizer part is deflected at the same load to a greater extent and thus the suppression of rolling motion can be made softer and finer tuned. The life of the stabilizer can be increased. The ability to use smaller diameter stabilizers reduces vehicle weight and reduces the cost of manufacturing the stabilizer. In addition, greater freedom for the arrangement of the stabilizer in the vehicle arise.
