Das System umfasst mindestens ein weiteres Federelement (4), das dem Federbein (5) zugeordnet ist. Mindestens ein Einstellelement (6) ist vorgesehen, mit dem eine Gesamtfederwirkung des mindestens einen weiteren Federelements (4) und der Fahrwerksfeder (2) mindestens zweistufig einstellbar ist.There is disclosed a system for changing the spring rate of a coil spring (2). The suspension spring (2) is installed in a strut (5). The system comprises at least one further spring element (4) associated with the strut (5). At least one adjusting element (6) is provided, with which an overall spring action of the at least one further spring element (4) and the chassis spring (2) is adjustable at least in two stages.
Description
Die vorliegende Erfindung betrifft ein System zum Einstellen der Federhärte einer Fahrwerksfeder. Die Fahrwerksfeder ist dabei in einem Federbein verbaut, wobei das System ein weiteres Federelement umfasst.The present invention relates to a system for adjusting the spring rate of a suspension spring. The suspension spring is installed in a strut, wherein the system comprises a further spring element.
Die deutsche Patentanmeldung
Die deutsche Patentschrift
Als Stand der Technik sind bei PKWs einstellbare Fahrwerke bekannt. Die Verstellung der Härte der Fahrwerke kann nur über Veränderungen am Dämpfer realisiert werden. Dazu werden z. B. die Ventile im Dämpfer verstellt oder die Viskosität des Öls im Dämpfer verändert. Eine Verstellung der Fahrwerksfeder, die einen erheblichen Einfluss auf die Härte des Fahrwerks hat, ist bisher nicht umgesetzt. Aus dem Rennsport, wie in
Der Erfindung liegt die Aufgabe zugrunde, ein System zum Einstellen der Federhärte einer Fahrwerksfeder zu schaffen, mit dem auf einfache Weise mindestens eine zweistufige Einstellung des Fahrwerks möglich ist.The invention has for its object to provide a system for adjusting the spring rate of a suspension spring, with the at least a two-stage adjustment of the chassis is possible in a simple manner.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein System zum Verändern der Federhärte einer Fahrwerksfeder, das die Merkmale des Anspruchs 1 umfasst.This object is achieved by a system for changing the spring rate of a suspension spring, comprising the features of claim 1.
Das System zum Verändern der Federhärte einer Fahrwerksfeder zeichnet sich dadurch aus, dass für die Verstellung der Fahrwerksfeder mindestens ein weiteres Federelement verwendet wird. Die Fahrwerksfeder selbst ist in einem Federbein verbaut. Das mindestens eine weitere Federelement ist der Fahrwerksfeder zugeordnet. Zum Verstellen der Federhärte der Fahrwerksfeder ist mindestens ein Einstellelement vorgesehen, mit dem eine Gesamtfederwirkung des weiteren Federbeins und der Fahrwerksfeder mindestens zweistufig einstellbar ist.The system for changing the spring stiffness of a suspension spring is characterized in that at least one further spring element is used for the adjustment of the suspension spring. The suspension spring itself is installed in a strut. The at least one further spring element is associated with the suspension spring. To adjust the spring stiffness of the suspension spring at least one adjustment is provided with which a total spring action of the other strut and the suspension spring is at least two stages adjustable.
Die grundlegende Idee für die Realisierung der Verstellung der Fahrwerksfeder ist, nicht nur die Fahrwerksfeder, sondern mindestens ein weiteres Federelement in dem System zu verbauen. Bei einer Parallelschaltung der Fahrwerksfeder und dem mindestens einen weiteren Federelement berechnet sich die Federsteifigkeit nach der Formel:
Das Gesamtsystem ist also härter, als die einzelne Fahrwerksfeder und das einzelne weitere Federelement. Durch die Nutzung der Fahrwerksfeder und des weiteren Federelements oder nur der Fahrwerksfeder, was durch Abkoppeln des weiteren Federelements erreicht wird, kann somit die Federsteifigkeit des Systems in mindestens zwei Stufen verstellt werden.The overall system is thus harder than the single suspension spring and the single additional spring element. By using the coil spring and the other spring element or only the suspension spring, which is achieved by decoupling the other spring element, thus the spring stiffness of the system can be adjusted in at least two stages.
Bei einer Reihenschaltung der Fahrwerksfeder und des mindestens einen weiteren Federelements berechnet sich die Federsteifigkeit des Gesamtsystems nach der Formel: In a series connection of the suspension spring and the at least one further spring element, the spring stiffness of the entire system is calculated according to the formula:
Das Gesamtsystem ist also weicher, als die einzelne Fahrwerksfeder und das mindestens eine weitere Federelement.The overall system is thus softer than the single suspension spring and the at least one further spring element.
Gemäß einer Ausgestaltung der Erfindung ist das weitere Element eine Feder, die der Fahrwerksfeder am Federbein nachgeschaltet ist. Zwischen der Fahrwerksfeder und dem mindestens einen weiteren Federelement ist eine Zwischenscheibe
Gemäß einer weiteren Ausführungsform der Erfindung ist das mindestens eine weitere Federelement mindestens ein Torsionsfederstab. Der Torsionsfederstab ist an einem ersten Ende über eine Koppelstange mit dem Federbein verbunden. An einem zweiten Ende ist der Torsionsfederstab über eine Kupplung mit einem festen Bauteil eines Fahrzeugs verbunden. Das feste Bauteil des Fahrzeugs kann z. B. die Karosserie oder der Achsträger sein.According to a further embodiment of the invention, the at least one further spring element is at least one torsion spring rod. The torsion bar is connected at a first end via a coupling rod with the strut. At a second end of the torsion bar is connected via a coupling with a solid component of a vehicle. The solid component of the vehicle may, for. B. be the body or the axle.
Gemäß einer noch weiteren Ausführungsform der Erfindung ist das mindestens eine weitere Federelement ein Federstab. Der Federstab ist an einem ersten Ende mit einer elektrisch verstellbaren Koppelstange mit dem Federbein verbunden. An einem zweiten Ende ist der Federstab fest mit dem festen Bauteil des Fahrzeugs verbunden, wobei das feste Bauteil die Karosserie oder der Achsträger sein kann. According to yet another embodiment of the invention, the at least one further spring element is a spring bar. The spring bar is connected at a first end with an electrically adjustable coupling rod with the strut. At a second end, the spring bar is fixedly connected to the fixed component of the vehicle, wherein the solid component may be the body or the axle.
