Abstract
Description
Die Erfindung betrifft eine Verbund- oder Koppellenkerachse mit den Merkmalen des Patentanspruchs 1.The The invention relates to a composite or coupling joint axis with the Features of claim 1.
Lenkbare Hinterachsen zählen zum Stand der Technik und wurden bereits in den 1980er Jahren von japanischen Automobilherstellern angeboten. Neben dem Einsatz von Aktuatoren als Spurlenker besteht die Möglichkeit, einen zentral am Chassis bzw. einem Hinterachsenhilfsrahmen angeordneten hydraulischen Aktuator für die aktive Spurbeeinflussung der Hinterachse zu realisieren. Dieser Aktuator verstellt abhängig von den Fahrzuständen des Fahrzeugs parallel die Spur der Hinterräder. Grundsätzlich wird zwischen zwei verschiedenen Mitlenkstrategien der Hinterräder unterschieden:
- a) Beim so genannten Parkieren erfolgt ein gegensinniges Lenken der Hinterräder zu den Vorderrädern bei langsamer Fahrt.
- b) Wenn bei schneller Fahrt die Hinterräder gleichsinnig zu den Vorderrädern gelenkt werden, unterstützt dies den Spurwechsel.
- a) In the so-called parking an opposite steering of the rear wheels to the front wheels takes place at low speeds.
- b) If the rear wheels are steered in the same direction to the front wheels during fast driving, this supports the lane change.
Alle Hinterachslenksysteme setzen eine drehbare Lagerung der Hinterräder voraus. Zudem müssen alle Verstellmechanismen auch in einer Neutrallage mit Energie versorgt werden, um die Position zu halten. Je nach Achstyp ist eine gelenkige Umsetzung der Spurführung mehr oder weniger aufwendig. Verbundlenker- oder Koppellenkerachsen haben den Vorteil eines relativ geringen Raumbedarfs bei leichter Montage und Demontage der ganzen Achse. Diese zu den Halbstarrachsen zählende Bauform ist relativ kostengünstig herstellbar und daher in großen Stückzahlen bei Serienfahrzeugen im Einsatz. Eine gelenkige Umsetzung der Spurführung ist bei diesem Achstyp jedoch verhältnismäßig aufwendig, da üblicherweise der Radträger bzw. die Radträgerplatte starr mit dem Längslenker der Verbundlenkerachse verbunden, insbesondere verschweißt ist und bei einer Hinterachsenlenkung unter entsprechender Abstützung gelenkig gelagert werden muss, was den Einsatz zusätzlicher Lenker zur Abstützung erforderlich macht. Die Firma Renault bietet seit 2008 den PKW Laguna GT mit einer Verbundlenkerhinterachse an, bei welcher die Hinterräder lenkbar sind. Die Anbindung der Radträger und die gelenkige Umsetzung der Spurführung sind relativ aufwendig.All Rear axle steering systems require a rotatable mounting of the rear wheels. In addition, must all adjusting mechanisms are also supplied with energy in a neutral position be to hold the position. Depending on the axle type is a hinged Implementation of the guidance more or less expensive. Compound link or coupling linker axles have the advantage of a relatively small space requirement with easier Assembly and disassembly of the whole axle. These to the semi-rigid axles counting Design is relatively inexpensive can be produced and therefore in large quantities in production vehicles in use. An articulated implementation of the tracking is However, in this type of axle relatively expensive, there usually the wheel carrier or the wheel carrier plate rigid with the trailing arm the composite beam axis connected, in particular welded and with a rear axle steering under appropriate support articulated must be stored, which requires the use of additional handlebars for support power. The company Renault offers since 2008 the car Laguna GT a torsion beam rear axle, in which the rear wheels steerable are. The connection of the wheel carriers and the articulated implementation of the tracking are relatively expensive.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine mitlenkende Hinterachse in kostengünstiger Verbund- oder Koppellenkerbauweise bereitzustellen.Of these, Based on the object of the invention, a mitlenkende Rear axle in less expensive To provide composite or coupling block construction.
Diese Aufgabe ist bei der erfindungsgemäßen Verbund- oder Koppellenkerachse mit den Merkmalen des Patentanspruchs 1 gelöst. Die Unteransprüche betreffen vorteilhafte Weiterbildungen.These Task is in the composite or coupling joint axis according to the invention solved with the features of claim 1. The dependent claims relate advantageous developments.
Bei der erfindungsgemäßen Verbund- oder Koppellenkerachse ist der Radträger mit einem drehbar gelagerten Dämpferbein verbunden. Üblicherweise wird der sich im Wesentlichen in Längsrichtung des Kraftfahrzeugs erstreckende Längslenker über Federn und Dämpferbeine an der Karosserie abgestützt, wobei diese Bauteile in der üblichen Bauform nicht an dem Radträger, sondern an einem separaten Federteller und einer entsprechenden Dämpferanbindung angreifen. Bei der Erfindung ist nunmehr vorgesehen, dass das Dämpferbein um seine Längsachse drehbar ausgebildet ist, so dass der Radträger, mit dem das Dämpferbein verbunden ist, um einen begrenzten Winkelbereich verschwenkt werden kann. Unter Verwendung eines solchen drehbaren Dämpferbeins können aufwendige Lagerungsteile im Bereich der Radträgeranbindung eingespart werden. Diese Teilereduktion führt zu einer Verschlankung und auch zu einer konstruktiven Vereinfachung der lenkbaren Verbund- oder Koppellenkerachse.at the composite or Koppellenkerachse is the wheel carrier with a rotatably mounted damper strut connected. Usually is essentially in the longitudinal direction of the motor vehicle extending trailing arm via springs and damper legs supported on the body, these components in the usual Design not on the wheel carrier, but on a separate spring plate and a corresponding damper connection attack. In the invention, it is now provided that the damper leg around its longitudinal axis is rotatably formed, so that the wheel, with the damper leg connected to a limited angular range can be pivoted. Using such a rotatable damper strut can be costly Storage parts are saved in the field of Radträgeranbindung. These Part reduction leads to a streamlining and also to a constructive simplification the steerable composite or coupling joint axis.
Bei dieser neuartigen Achskonstruktion wird der Radträger von dem Dämpferbein geführt. Zusätzlich zu dem Dämpferbein ist der Radträger über ein Gelenk an dem Längslenker gelagert, um die notwendigen Seitenkräfte aufzunehmen. Wie bei einem McPherson-Federbein handelt es sich bei dem Gelenk vorzugsweise um ein Kugelgelenk, über das der Radträger mit dem Längslenker verbunden ist. Das Dämpferbein kann dementsprechend gegenüberliegend dem Kugelgelenk an dem Radträger befestigt sein. Entscheidend ist, dass der Radträger um eine definierte Achse schwenkbar ist. Insgesamt wird der Radträger somit über das Kugelgelenk und das Dämpferbein geführt.at This novel axle construction becomes the wheel carrier of the strut guided. additionally to the strut is the wheel carrier over a joint on the trailing arm stored to receive the necessary lateral forces. Like a McPherson strut it is the joint is preferably a ball joint over the the wheel carrier with the trailing arm connected is. The shock absorber leg can therefore be opposite the ball joint on the wheel be attached. It is crucial that the wheel carrier around a defined axis is pivotable. Overall, the wheel is thus on the ball joint and the shock absorber leg guided.
Die Umsetzung der Spuränderung, dass heißt, das Verschwenken des Radträgers, erfolgt aus einer Linearbewegung eines Aktuators. Hierbei kann es sich um einen Zentral- oder Einzelaktuator handeln, der elektrisch oder hydraulisch betrieben wird. Die Konfiguration des Aktuators spielt für die Ausgestaltung des drehbar gelagerten Radträgers im Rahmen der vorliegenden Erfindung eine untergeordnete Rolle. Es ist allerdings zu berücksichtigen, dass die Sturzkräfte durch die Verbund- oder Koppellenkerachse aufzunehmen sind, während die Spurkräfte hauptsächlich auf den Aktuator übertragen werden.The Implementation of the track change, that means, the pivoting of the wheel carrier, takes place from a linear movement of an actuator. It can do this be a central or single actuator, the electric or hydraulically operated. The configuration of the actuator plays for the embodiment of the rotatably mounted wheel carrier in the context of the present Invention a minor role. It is, however, to be considered that the fall forces be absorbed by the composite or coupling link axis, while the Trace forces mainly on transmit the actuator become.
Ein weiterer Vorteil der Erfindung ist, dass die maximalen Spurwinkel zum Verstellen des Radträgers im Rahmen der Erfindung nur durch den zur Verfügung stehenden Einbauraum des Rades begrenzt werden. Normalerweise werden die maximalen Spurwinkel innerhalb von +/–4° realisiert, wobei der Hinterradlenkbereich zur Fahrstabilisierung des Kraftfahrzeugs meistens kleiner +/–1° liegt.One Another advantage of the invention is that the maximum toe angle for adjusting the wheel carrier within the scope of the invention only by the available installation space of the Rades be limited. Usually the maximum toe angles realized within +/- 4 °, wherein the rear wheel steering area for driving stabilization of the motor vehicle usually less than +/- 1 °.
