Abstract
Description
Die Erfindung betrifft eine Fahrerkabinenfederung mit zwei Luft federbälgen.The invention relates to a driver's cab suspension with two air bellows.
Fahrerkabinenfederungen sind heute am Kabinenboden angelenkt (vgl. US 44 51 079). Durch die Abstützung der Kabine am Kabinen boden addiert sich die durch die Fliehkraft bedingte Querneigung von Rahmen und Fahrerhausfederung. Eine Einflußnahme auf die Fe derkennung über eine Hebelanlenkung ist wegen der erforderlichen Bauhöhe nur schwer realisierbar.Driver's cab suspension is hinged to the cab floor today (see US 44 51 079). By supporting the cabin on the cabins the cross slope caused by centrifugal force is added of frame and cab suspension. An influence on the Fe Detection via a lever linkage is necessary because of the Height is difficult to achieve.
Der Erfindung liegt die Aufgabe zugrunde, die Ausgleichsmöglich keit der Rahmenquerneigung zu begrenzen.The invention has for its object the compensation possible limit the frame bank.
Diese Aufgabe wird bei einer Fahrerkabinenfederung mit zwei Luft federbälgen erfindungsgemäß gelöst durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale.This task is done in a cab suspension with two air Spring bellows according to the invention solved by the in the characteristic Part of claim 1 specified features.
Die Fahrerkabine weist bei allen Betriebsarten, also statischen und dynamischen, weniger Querneigung auf. Dies ergibt einen gro ßen ergonomischen Vorteil. Durch eine Längenänderung der unteren Stützstrebe kann der Längsneigungswinkel der Fahrerkabine und da mit z. B. die Leuchtweite der Scheinwerfer reguliert werden.The driver's cab shows static in all operating modes and dynamic, less bank. This makes a big one ergonomic advantage. By changing the length of the lower one Support strut can be the longitudinal inclination angle of the driver's cabin and there with z. B. the headlight range can be regulated.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispie les unter Bezug auf die Zeichnung näher erläutert. The invention is based on an exemplary embodiment les explained with reference to the drawing.
Die Fahrerkabine ist über dem Schwerpunkt an einem Überrollbügel (1) aufgehängt (5). Die obere Aufhängung besteht aus zwei Feder bälgen (3) sowie zwei Dreieckslenkern (2), die für die seitliche Stabilität sorgen. Zugleich ermöglichen sie den vertikalen Hub. Die Federabstützung besteht aus einem System von Hebeln (z. B. 6). Durch die Veränderung der Hebelwinkel kann die Federkennung pro gressiv oder degressiv unterstützt werden.The driver's cab is suspended above the center of gravity on a roll bar ( 1 ) ( 5 ). The upper suspension consists of two bellows ( 3 ) and two wishbones ( 2 ), which ensure lateral stability. At the same time, they enable vertical lifting. The spring support consists of a system of levers (e.g. 6 ). By changing the lever angle, the spring detection can be supported progressively or degressively.
Die untere Abstützung der Beschleunigungsmomente parallel zur Fahrtrichtung übernimmt eine Strebe (4), die an beiden Enden ela stisch oder in einem Kugelgelenk aufgehängt ist. So ist ein Aus lenken quer zur Fahrtrichtung möglich. Durch eine Längenverstel lung der Strebe kann der Längsneigungswinkel der Fahrerkabine zur Fahrebene justiert werden. Außerdem kann durch eine entsprechende Verlängerung oder Lösen der Verbindungsstrebe (4) die Kabine nach vorne geschwenkt und der Serviceraum unter der Kabine zugänglich gemacht werden.The lower support of the acceleration moments parallel to the direction of travel is carried out by a strut ( 4 ), which is suspended at both ends ela stically or in a ball joint. This makes it possible to steer across the direction of travel. The longitudinal inclination of the driver's cab relative to the driving level can be adjusted by adjusting the length of the strut. In addition, the cabin can be pivoted forward by a corresponding extension or loosening of the connecting strut ( 4 ) and the service room under the cabin can be made accessible.
