Abstract
Description
Es ist bekannt, daß bei höhenverstellbaren Fahrwerken für PKW die Federrate des Federbeines unabhängig von der eingestellten Vorspannung unverändert bleibt. Um die Federrate auf den verbleibenden Federweg abzustimmen, ist es erforderlich, die Hauptfeder auszutauschen. Dies ist mit einem hohen Montageaufwand verbunden. Der in den Patentansprüchen angegebenen Erfindung liegt die Möglichkeit zugrunde, die Federrate des Federbeines in Bezug auf die vorhandene Einstellung und den damit verbundenen Einfederweg ohne jeglichen Montageaufwand anzupassen.It is known that in the case of height-adjustable undercarriages for cars, the spring rate of the shock absorber remains unchanged regardless of the set preload. To the spring rate on the the remaining spring travel, it is necessary to replace the main spring. This is with a high installation effort. The invention specified in the claims lies Possibility based on the spring rate of the shock absorber in relation to the existing setting and the related deflection without adapt any assembly effort.
Diese Möglichkeit wird durch die in den Patentansprüchen aufgeführten Merkmale gegeben.This possibility is given by the features listed in the claims.
Die mit der Erfindung erzielten Vorteile bestehen darin, daß sich die Federrate des Federbeines immer dem Federweg anpaßt und somit eine einfache Bedienung und der Wegfall von Montagearbeiten erzielt wird.The advantages achieved with the invention are that the spring rate of the strut always adapts to the travel and thus achieves simple operation and the elimination of assembly work becomes.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below described.
Es zeigtIt shows
Fig. 1 Schnittschema eines Federbeines, mit der Besonderheit, daß zwischen oberen Federteller (6) und Federbeingehäuse (8) eine progessive Zusatzfeder installiert ist. Fig. 1 sectional diagram of a shock absorber, with the special feature that a progressive additional spring is installed between the upper spring plate ( 6 ) and shock absorber housing ( 8 ).
Bringt man den unteren Federteller auf ein hohes Niveau, steht viel Federweg zur Verfügung und die progressive Zusatzfeder (1) ist relativ entspannt, somit bringt sie eine geringe Federkraft auf. Diese Federkraft addiert sich auf die Federkraft der Hauptfeder (2).If you raise the lower spring plate to a high level, there is a lot of travel available and the progressive additional spring ( 1 ) is relatively relaxed, so it has a low spring force. This spring force is added to the spring force of the main spring ( 2 ).
Bringt man den unteren Federteller in eine tiefere Position, so verringert sich auch der verbleibende Federweg und die Federkraft der progressiven Zusatzfeder (I) erhöht sich. Diese Federkraft addiert sich wiederum zur Federkraft der Hauptfeder (2), so daß die Federkraft des Komplettfederbeines höher liegt als bei hoch eingestelltem Federteller. Ohne die Zusatzfeder (1) stünde immer eine gleichbleibende Federkraft zur Verfügung unabhängig davon, in welcher Lage sich der untere Federteller befindet.If the lower spring plate is brought into a lower position, the remaining spring travel is also reduced and the spring force of the progressive additional spring (I) is increased. This spring force is in turn added to the spring force of the main spring ( 2 ), so that the spring force of the complete spring strut is higher than when the spring plate is set high. Without the additional spring ( 1 ), a constant spring force would always be available, regardless of the position of the lower spring plate.
Der Vorteil dieser Konstruktion liegt darin, daß sich die Federkraft dem jeweils eingestellten Federweg anpaßt.The advantage of this construction is that the spring force is adjusted to the current one Adjusts travel.
