Description
Die Erfindung betrifft eine Mehrlenker-Hinterradachse für ein Kraftfahrzeug zur Verbindung eines Radträgers an einer Fahrzeugkarosserie mit in einer oberen Lenkerebene angeordneten Lenkarmen und einem in einer unteren Lenkerebene angeordneten Trapezlenker, wobei die in der oberen Lenkerebene angeordneten Lenkarme als Querlenker ausgebildet sind und wobei der Trapezlenker über einen Koppellenker mit dem Radträger verbunden ist. The invention relates to a multi-link rear wheel axle for a motor vehicle for connecting a wheel carrier to a vehicle body arranged in an upper arm level steering arms and arranged in a lower arm level trapezoidal link, wherein arranged in the upper arm level steering arms are designed as wishbones and wherein the trapezoidal over a coupling link is connected to the wheel carrier.
Mehrlenker-Hinterradachsen sind hinlänglich bekannt. Hierbei dienen sogenannte Lenkarme, die in einer unteren Lenkerebene und in einer oberen Lenkerebene angeordnet sind, dazu, möglichst fünf der sechs Freiheitsgrade eines Körpers im Raum aufzunehmen. Lediglich ein Freiheitsgrad für die Ein- und Ausfallfederung des Fahrzeugrades verbleibt. Eine derartige Konstruktion sollte natürlich einhergehen mit einem maximal möglichen Fahrkomfort, wobei gewährleistet sein muss, dass beim Auftreten von jeglichen Längs- und Seitenkräften auf das Fahrzeug, das Fahrzeug in der gewünschten Spur verbleibt. Insbesondere sind sogenannte Fünflenker-Hinterradachsen bekannt, bei denen fünf einzelne Lenkerarme eine Verbindung von der Fahrzeugkarosserie zum Radträger herstellen. Diese Art einer Mehrlenker-Hinterradachse bietet zwar einen sehr hohen Komfort und eine sehr große Variabilität hinsichtlich der Einstellbarkeit des Radträgers, benötigen jedoch einen sehr viel größeren Bauraum und damit auch verbunden einen höheren Montageaufwand als Mehrlenker-Hinterradachsen, die beispielsweise Dreieckslenkarme nutzen. Multi-link rear axles are well known. Here are so-called steering arms, which are arranged in a lower arm level and in an upper arm level, to accommodate as many as possible five of the six degrees of freedom of a body in space. Only one degree of freedom for the input and failure suspension of the vehicle wheel remains. Such a construction should of course be accompanied by a maximum possible ride comfort, it must be ensured that when any longitudinal and lateral forces on the vehicle, the vehicle remains in the desired lane. In particular, so-called five-link rear wheel axles are known in which five individual link arms make a connection from the vehicle body to the wheel carrier. Although this type of multi-link rear axle offers a very high level of comfort and a very large variability in the adjustability of the wheel, but require a much larger space and thus also a higher assembly costs than multi-link rear axles, for example, use triangular steering arms.
Darüber hinaus ist es aus der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Mehrlenker-Hinterradachse zu schaffen, die die Vorteile einer echten Fünflenker-Hinterradachse mit den Vorteilen einer Integrallenker-Hinterradachse auf einfache und kostengünstige Weise verbindet. The invention is therefore an object of the invention to provide a multi-link rear wheel axle, which combines the advantages of a true five-link rear wheel axle with the advantages of integral steering rear axle in a simple and cost-effective manner.
Die Aufgabe wird dadurch gelöst, dass in der unteren Lenkerebene ein als Längslenker ausgebildeter weiterer Lenkarm und ein zweiter Koppellenker zur Verbindung des Trapezlenkers mit der Fahrzeugkarosserie vorgesehen sind. Auf diese Weise sind fast alle kinematischen und elastokinematischen Kenngrößen separat einstellbar, obwohl der Aufbau einfacher und damit kostengünstiger als der bei einer reinen Fünflenker-Hinterradachse ist. Insbesondere kann ein hoher Längsfederungskomfort bei steifer Bremsmomentenabstützung und ein hoher Längsfederungskomfort in Lastrichtung erreicht werden. Auch sind eine bessere Elastokinematik und geringere Spurstangenkräfte realisierbar. The object is achieved in that in the lower link level designed as a trailing arm further steering arm and a second coupling link for connecting the trapezoidal link to the vehicle body are provided. In this way, almost all kinematic and elastokinematischen parameters are separately adjustable, although the structure is simpler and thus cheaper than that of a pure five-link rear wheel axle. In particular, a high longitudinal suspension comfort can be achieved with stiff braking torque support and a high longitudinal suspension comfort in the load direction. Also, a better elastokinematics and lower tie rod forces can be realized.
In einer besonders vorteilhaften Ausführungsform ist der in der oberen Lenkerebene, in Fahrrichtung gesehen, vordere Querlenker als Spurstange ausgebildet. Hierbei kann, um den Fahrkomfort noch weiter zu vergrößern, die Spurstange als aktive Spurstange ausgebildet sein. In a particularly advantageous embodiment, the seen in the direction of travel, the front wishbone in the upper arm level, designed as a tie rod. In this case, in order to increase the ride comfort even further, the tie rod may be formed as an active tie rod.
In einer bevorzugten Ausführungsform ist es weiterhin vorgesehen, dass in der unteren Lenkerebene der Längslenker unterhalb des Trapezlenkers verläuft. Es ist jedoch auch denkbar, dass der Längslenker nicht am Radträger abgestützt ist, sondern direkt radträgerseitig am Trapezlenker, wodurch sich günstigere Bauraumverhältnisse ergeben. In a preferred embodiment, it is further provided that runs in the lower link level of the trailing arm below the trapezoidal link. However, it is also conceivable that the trailing arm is not supported on the wheel, but directly wheel carrier side on the trapezoidal link, resulting in more favorable space conditions.
In einem vorteilhaften Ausführungsbeispiel sind die Koppelelemente an einem Schenkel des Trapezlenkers angekoppelt. Sie können jedoch auch diagonal versetzt angeordnet sein. In an advantageous embodiment, the coupling elements are coupled to a leg of the trapezoidal link. However, they can also be arranged diagonally offset.
Des Weiteren kann der Trapezlenker eine Aussparung zur Aufnahme einer Tragfeder aufweisen. Hierdurch wird die erfindungsgemäße Mehrlenker-Hinterradachse hinsichtlich Montagefreundlichkeit und Bauraumoptimierung noch weiter verbessert. Darüber hinaus kann der Trapezlenker noch einen Anlenkpunkt für ein Dämpfungsorgan aufweisen. Furthermore, the trapezoidal link may have a recess for receiving a suspension spring. As a result, the multi-link rear wheel axle according to the invention is further improved in terms of ease of assembly and space optimization. In addition, the trapezoidal link can still have a point of articulation for a damping element.
Nachfolgend wird die Erfindung anhand einer bevorzugten Ausführungsform und unter Bezugnahme auf die anliegende Zeichnung näher erläutert. Hierbei zeigt: The invention will be explained in more detail with reference to a preferred embodiment and with reference to the accompanying drawings. Hereby shows:
