Abstract
Description
Die Erfindung betrifft einen Vierpunktlenker zur Anbindung einer Starrachse eines Nutzfahrzeugs an den Fahrzeugrahmen mit gekreuzten Lenkerarmen, welche an ihren Enden Anlenkstellen aufweisen, von denen wenigstens zwei Anlenkstellen an der Starrachse und wenigstens zwei Anlenkstellen mit dem Fahrzeugrahmen gelenkig zu verbinden sind.The The invention relates to a four-point link for connecting a rigid axle a commercial vehicle to the vehicle frame with crossed arms, which have at their ends articulation points, of which at least two articulation points on the rigid axle and at least two articulation points To be articulated to the vehicle frame.
Ein
derartiger Vierpunktlenker ist aus
Aufgabe der Erfindung ist es, einen Vierpunktlenker der eingangs genannten Art zu schaffen, welcher aus einfachen Konstruktionselementen herstellbar ist.task The invention is a four-point link of the aforementioned Art to create, which can be produced from simple construction elements is.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst, wobei die Unteransprüche vorteilhafte Weiterbildungen der Erfindung angeben.These The object is achieved by the characterizing features of claim 1, wherein the dependent claims indicate advantageous developments of the invention.
Die erfindungsgemäße Lösung beinhaltet zwei gekreuzte übereinander angeordnete Metallfederblätter, insbesondere aus Federstahl, welche die Lenkerarme des Vierpunktlenkers bilden. An ihrer Kreuzungsstelle sind die beiden Metallfederblätter mit wenigstens einem Verbindungselement miteinander verbunden. Hierdurch wird eine Spannverbindung über die Gesamthöhe der beiden an der Kreuzungsstelle übereinander liegenden Metallfederblätter gebildet. Das Verbindungselement bzw. die Verbindungselemente an der Kreuzungsstelle werden vorzugsweise von Schraubenverbindungen, beispielsweise Dehnschrauben gebildet. Es können hierfür jedoch auch eine Bride oder mehrere Briden oder dergleichen vorgesehen sein.The Solution according to the invention includes two crossed over each other arranged metal spring leaves, in particular made of spring steel, which the control arms of the four-point link form. At their intersection, the two metal spring leaves with at least one connecting element connected to each other. hereby is a clamping connection over the total height the two formed at the intersection of metal spring leaves. The connecting element or the connecting elements at the intersection are preferably screw connections, such as expansion screws educated. However, it can do this also a Bride or more Briden or the like provided be.
Auf diese Weise wird an der Kreuzungsstelle eine Spannverbindung der beiden Metallfederblätter erreicht. Die Spannverbindung ist derart, dass die aus der Fahrdynamik des Nutzfahrzeugs resultierenden Kräfte aufgenommen werden und rückstellenden Momente, welche auf den Fahrzeugrahmen und die Starrachse in die jeweilige Nulllage rückstellend wirken, vom Vierpunktlenker erzeugt werden.On This way, at the intersection of a clamping connection of reached both metal spring leaves. The clamping connection is such that the from the driving dynamics of the Commercial vehicle resulting forces be absorbed and restoring moments, which on the vehicle frame and the rigid axle in the respective Resetting zero position act, be generated by the four-point link.
Bei der Verwendung von vier oder mehr Verbindungselementen im Bereich der Kreuzungsstelle sind diese vorzugsweise außerhalb der auf Biegung und/oder Torsion beanspruchten Querschnitte der Metallfederblätter angeordnet. Zum Ausgleich von Dehnungsunterschieden zwischen den gekreuzten übereinander angeordneten Metallfederblättern können Zwischenlagen, insbesondere im Bereich der Verbindungselemente vorgesehen sein. Diese Zwischenlagen können scheibenförmig oder hülsenförmig ausgebildet sein. Bei hülsenförmiger Ausbildung der Zwischenlage erstreckt sich die Hülse im wesentlichen zwischen den beiden horizontalen Mitten der übereinander liegenden Metallfederblätter. Die Berührungsflächen zwischen der hülsenförmigen Zwischenlage und den Metallfederblättern liegt dann im neutralen Bereich der von außen auf die Federblätter einwirkenden Kräfte.at the use of four or more connectors in the range the crossing point, these are preferably outside the bend and / or Torsion claimed arranged cross sections of the metal spring leaves. To compensate for differences in stretching between the crossed one over the other arranged metal spring leaves can Intermediate layers, in particular provided in the region of the connecting elements be. These liners can disc-shaped or sleeve-shaped be. When sleeve-shaped training of Interlayer, the sleeve extends substantially between the two horizontal centers of the overlapping metal spring leaves. The Interfaces between the sleeve-shaped intermediate layer and the metal spring leaves then lies in the neutral region of the externally acting on the spring leaves Forces.
Der Vierpunktlenker kann die aus der Fahrdynamik des Nutzfahrzeugs hohen Kräfte aufnehmen. Diese Kräfte setzen sich im wesentlichen aus Längsführungsbeanspruchungen, aus durch Bremsmomente verursachten Abstützkräften sowie Kräften, welche aus der Querführungsfunktion für den Fahrzeugaufbau und die Starrachse resultieren, zusammen. Außerdem kann der Vierpunktlenker zum Abbau von Wankbewegungen rückstellende Drehmomente aufnehmen und übertragen.Of the Four-point handlebars can be high from the driving dynamics of the commercial vehicle personnel take up. These forces essentially consist of longitudinal guiding stresses caused by braking moments supporting forces and forces, which from the transverse guidance function for the Vehicle body and the rigid axle result, together. In addition, can the four-point link for the dismantling of rolling movements resetting Record and transmit torques.
Anhand der Figuren wird an Ausführungsbeispielen die Erfindung noch näher erläutert.Based The figures will be based on embodiments the invention even closer explained.
