Abstract
Description
Die Erfindung bezieht sich auf ein Fahrzeug oder einen Fahrzeuganhänger, bestehend aus einem Rahmen an dem eine schwenkbar gelagerte Achse befestigt ist, wobei die Achse mit einem ein Fahrzeugrad tragenden Längslenker versehen ist und dass zwischen dem Längslenker und dem Rahmen ein Dämpfungselement angeordnet ist.The invention relates to a vehicle or a vehicle trailer, consisting of a frame to which a pivotally mounted axle is attached, wherein the axle is provided with a trailing arm supporting a vehicle and that between the trailing arm and the frame, a damping element is arranged.
Es sind bereits Fahrzeuge oder Fahrzeuganhänger bekannt, bei denen am Rahmen eines Fahrzeuges eine Gummifederachse befestigt wird (z. B.
Derartige Gummifederachsen werden mit einem Schwingungsdämpfer kombiniert, so dass eine weichere Gummifeder und damit eine weniger steile Federkennung eingesetzt werden kann und der Fahrzeugaufbau zwecks Komfortgewinns mehr Federungsweg ausführen kann. Hierbei wächst zwar das Gummivolumen der Gummifederachse, so dass die Baugröße negativ beeinflusst wird, des Weiteren sind jedoch hydraulische Schwingungsdämpfer erforderlich, die notwendig sind, damit von Gesetz her eine Geschwindigkeitsklasse bis zu 100 km/h zugelassen werden kann.Such rubber spring axles are combined with a vibration damper, so that a softer rubber spring and thus a less steep spring rate can be used and the vehicle body can perform more suspension travel for the sake of comfort. Although this increases the rubber volume of the rubber spring axis, so that the size is adversely affected, but further hydraulic vibration dampers are required, which are necessary for lawfully a speed class up to 100 km / h can be allowed.
Nachteilig ist bei dieser Konstruktion, dass bei Verwendung einer Gummifederachse der Federweg auch bei Anwendung bei einem Stoßdämpfer nicht ausreichend ist, um die von der Fahrbahn eingeleitete Energie harmonisch abklingen zu lassen, so dass sich die Restenergie in unerwünschter Weise auf das Zugfahrzeug überträgt. Diese Störungen werden z. B. beim Ziehen von Boots- und Pferdeanhängern oder auch von Wohnwagenanhängern im Zugfahrzeug als unangenehm empfunden. Des Weiteren ist von Nachteil, dass sich die Gummistränge der Gummifederachse über die Zeit gesehen bleibend verformen, so dass der Aufbau eines Fahrzeughängers an Bodenfreiheit verliert.A disadvantage of this construction is that when using a rubber spring axis of the travel even when applied to a shock absorber is not sufficient to let the energy introduced by the road harmonically decay, so that the residual energy is transmitted in an undesirable manner to the towing vehicle. These disorders are z. B. when pulling boat and horse trailers or caravans in the towing vehicle felt uncomfortable. Furthermore, it is disadvantageous that deform the rubber strands of the rubber spring axis seen over time so that the construction of a vehicle hanger loses ground clearance.
Darüber hinaus sind selbstpumpende, niveauregelnde Kolben-Zylinder-Aggregate bekannt (z. B.
Aufgabe der Erfindung ist es, eine Gummifederachse für ein Fahrzeug oder einen Fahrzeuganhänger derart zu verbessern, dass Restenergie durch die von der Fahrbahn eingeleiteten Schwingungen nicht in das Zugfahrzeug übertragen wird und dass das Setzen der Gummistränge in der Gummifederachse durch geeignete Maßnahmen eliminiert werden kann.The object of the invention is to improve a rubber spring axle for a vehicle or a vehicle trailer such that residual energy is not transmitted by the initiated from the road vibrations in the towing vehicle and that the setting of the rubber strands in the rubber spring axis can be eliminated by appropriate measures.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass als Dämpfungselement ein selbstpumpendes, niveauregelndes Kolben-Zylinder-Aggregat vorgesehen ist.To achieve this object, the invention provides that a self-pumping, level-regulating piston-cylinder unit is provided as a damping element.
Hierbei ist von Vorteil-, dass in einer Gummifederachse anstelle eines Schwingungsdämpfers ein selbstpumpendes, niveauregelndes Kolben-Zylinder-Aggregat eingesetzt wird, welches in Abstimmung mit der Gummifeder einen vorbestimmten Traganteil und einen vorbestimmten Dämpfungsanteil übernimmt. Die Gesamtfederrate beider Federn, nämlich der Gummifederachse und des selbstpumpenden, hydropneumatischen Kolben-Zylinder-Aggregats kann damit so ausgelegt werden, dass im Fahrbetrieb ein wesentlich höherer Federweg ausgeführt werden kann. Hierdurch entsteht der Vorteil, dass die durch die Fahrbahn eingeleitete Energie direkt im Bereich der Gummifederachse bzw. des Kolben-Zylinder-Aggregats abgebaut wird, so dass keine Restenergie an das Zugfahrzeug weitergegeben wird.It is advantageous - that in a rubber spring axis instead of a vibration damper, a self-pumping, level-adjusting piston-cylinder unit is used, which assumes a predetermined carrying component and a predetermined damping component in coordination with the rubber spring. The total spring rate of both springs, namely the rubber spring axis and the self-pumping, hydropneumatic piston-cylinder unit can thus be designed so that when driving a much higher travel can be performed. This results in the advantage that the energy introduced by the roadway is dissipated directly in the area of the rubber spring axle or the piston-cylinder unit, so that no residual energy is passed on to the towing vehicle.
Nach einem wesentlichen Merkmal ist vorgesehen, dass die Achse als Gummifederachse oder als Drehstabfederung ausgebildet ist.According to one essential feature, it is provided that the axle is designed as a rubber spring axle or torsion bar suspension.
Eine weitere vorteilhafte Ausgestaltung liegt vor, indem das Kolben-Zylinder-Aggregat zwischen der Achse und der Befestigung des Fahrzeugrads am Längslenker fixiert ist.A further advantageous embodiment is provided by the piston-cylinder unit is fixed between the axis and the attachment of the vehicle wheel to the trailing arm.
In vorteilhafter Weise ist vorgesehen, dass das Kolben-Zylinder-Aggregat den Rahmen des Fahrzeugs oder des Fahrzeuganhängers auf mindestens ein vorgegebenes Niveau einstellt.Advantageously, it is provided that the piston-cylinder unit adjusts the frame of the vehicle or the vehicle trailer to at least a predetermined level.
Eine weitere Ausgestaltung sieht vor, dass das Kolben-Zylinder-Aggregat aus einem mit einem Dämpfungskolben versehenen Arbeitszylinder und einer durch die hohle Kolbenstange gebildeten Kolbenpumpe besteht.A further embodiment provides that the piston-cylinder unit consists of a working cylinder provided with a damping piston and a piston pump formed by the hollow piston rod.
Durch die vorgenannten Merkmale lässt sich bei Anhängern, aber auch bei motorisierten Fahrzeugen, die bisher bekannte Gummifederachse, wie auch als alternative eine Drehstabfederung komfortmässig verbessern. Dem Kostenvorteil der vorgestellten Achsen steht der Nachteil eines relativ schlechten Fahrverhaltens entgegen. Der Federweg zum restlosen harmonischen Abbau der Schwingungen müsste größer sein, um die ungedämpfte Restenergie auf ein Zugfahrzeug oder den Vorderwagen eines Fahrzeuganhängers nicht zu übertragen.Due to the aforementioned features can be in trailers, but also in motorized vehicles, the previously known rubber spring axis, as well as an alternative to improve a torsion bar comfort. The cost advantage of the presented axes is the disadvantage of a relatively poor driving behavior. The travel to complete harmonic degradation of the vibrations would have to be greater to the undamped Do not transfer residual energy to a towing vehicle or the front of a vehicle trailer.
Eine steil progressive Gummifederrate erzeugt dabei mit wachsender Zuladung größer werdende Aufbaueigenfrequenzen, wobei sich im Laufe der Zeit die Gummistränge der Gummifederachse setzen, so dass sich der Fahrzeugaufbau in seiner Bodenfreiheit verändert.A steeply progressive rubber spring rate generates increasing body fatigue frequencies as the payload increases, with the rubber strands of the rubber spring axis settling over time so that the vehicle body structure changes in its ground clearance.
Bei Anwendung eines hydraulischen Niveauregelelementes werden die Gummistränge der Gummifederachse entlastet, so dass sich die Gummifederachse zusammen mit dem Niveauregelelement den Trag- und Dämpfungsanteil aufteilen.When using a hydraulic level control element, the rubber strands of the rubber spring axle are relieved, so that the rubber spring axle together with the level control element divide the load and damping component.
Beispielsweise ist das Aufbaugewicht eines Wohnanhängers, je nach Ausstattung, unterschiedlich groß, so dass durch die Anwendung eines hydraulischen Niveauregelelementes problemlos die Höhe des Fahrzeugaufbaus einstellbar ist.For example, the body weight of a trailer, depending on the equipment, different sizes, so that the height of the vehicle body is easily adjustable by the application of a hydraulic level control element.
Des Weiteren ist von Vorteil, dass im Zusammenspiel eine Gummifederachse mit einem hydraulischen Niveauregelelement eine lastabhängige Federratenanpassung, das heißt in jedem Beladungszustand wird automatisch eine dazu passende Federrate zugeordnet, sowie eine annähernd gleich bleibende, komfortverbessernde Aufbaueigenfrequenz (Zuladungsunabhängig) als auch eine lastabhängige Dämpfung (mehr Zuladung, mehr Dämpfung) erzielt werden kann.Furthermore, it is advantageous that in conjunction a rubber spring axis with a hydraulic level control element load-dependent spring rate adjustment, that is automatically assigned a matching spring rate in each load condition, as well as an approximately constant, comfort improving Aufbäuserigenfrequenz (load independent) and a load-dependent damping (more Payload, more damping) can be achieved.
Die beidseitig angeordneten hydraulischen Niveauregelelemente gleichen darüber hinaus auch eine Fahrzeugschrägstellung, in Querrichtung gesehen, aus, da jede Achshälfte für sich das Fahrzeugniveau eigenständig regeln kann. Diese Vorteile lassen sich generell ohne Zufuhr von Fremdenergie erzielen.In addition, the hydraulic level control elements arranged on both sides also compensate for a vehicle inclination, viewed in the transverse direction, since each half of the axle can regulate the vehicle level independently. These advantages can generally be achieved without the supply of external energy.
Um eine Niveauerzielung im Stand des Fahrzeugs zu erreichen, also bevor das Fahrzeug bewegt wird, ist nach einer weiteren Ausführungsform vorgesehen, dass das selbstpumpende, niveauregelnde Kolben-Zylinder-Aggregat mit einer Standregelung versehen ist.In order to achieve a leveling in the state of the vehicle, so before the vehicle is moved, it is provided according to a further embodiment, that the self-pumping, level-adjusting piston-cylinder unit is provided with a level control.
