- the bottom plates 16 approximately centrally cams 18 have.
- the cams engage in grooves 20 which are provided circumferentially in rollers 22 (see. Fig. 1a ).
- the rollers are arranged in the crawler support 12.
- the crawler 14 is driven by a drive wheel 24.
- Object of the present invention is to develop a generic suspension such that a dropping down of the crawler can be effectively prevented even when driving over bumps.
- the object is achieved on the basis of a chassis according to the preamble of claim 1 by the combination with the features of the characterizing part of claim 1.
- the holes bent screws can be used and held, which define the retaining plate on the bottom plate.
- the holes cast in the top of the bottom plates which are required for holding the cores during the casting process, can be used to mount retaining plates.
- two cranked screws are connected to one another via a transverse web, over which the screws introduced into the base plates are supported on this.
- the attachable to these screws holding plates can be firmly connected, for example, two nuts with the bottom plate.
- the holding plates can be made for example as a casting.

Description
Die Erfindung betrifft ein Fahrwerk, vorzugsweise für einen Raupenkran, mit einer auf einem Raupenträger laufenden Raupenkette, die aus gelenkig miteinander verbundenen Bodenplatten besteht, wobei auf den Bodenplatten Nocken ausgebildet sind, die in Nuten von im Raupenträger angeordneten Laufrollen eingreifen, wobei Sie die Raupenkette unter den Laufrollen seitliche zentrieren.The invention relates to a chassis, preferably for a crawler crane, running on a caterpillar track crawler consisting of articulated floor plates, which are formed on the bottom plates cams, which engage in grooves arranged in the crawler track rollers, taking the crawler under Center the rollers on the side.
Ein Fahrwerk gemäß dem Oberbegriff des Anspruchs 1 ist aus
Eine Raupenkette nach dem Stand der Technik ist beispielsweise in
Bei der zuvor beschriebenen Bauausführung besteht insbesondere beim Raupenkran das Problem, dass die Kette infolge der hohen Kräfte sehr schwer ist und demzufolge bei geringsten Bodenunebenheiten sehr stark durchhängt, wie dies in der

Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Fahrwerk derart weiterzubilden, dass ein Herunterspringen der Raupenkette auch beim Überfahren von Unebenheiten wirksam verhindert werden kann.Object of the present invention is to develop a generic suspension such that a dropping down of the crawler can be effectively prevented even when driving over bumps.
Erfindungsgemäß wird die Aufgabe ausgehend von einem Fahrwerk nach dem Oberbegriff des Anspruchs 1 durch die Kombination mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst.According to the invention the object is achieved on the basis of a chassis according to the preamble of claim 1 by the combination with the features of the characterizing part of claim 1.
Demnach sind am Untergurt des Raupenträgers seitlich zwei sich im wesentlichen über die Länge des Raupenträgers erstreckende Leitbleche angeordnet, die von an den Bodenplatten der Raupenketten angeordneten Halteplatten hintergriffen werden. Hierdurch wird in einfacher Weise erreicht, dass die Raupenketten auch bei unwegsamem Gelände nicht von dem Raupenkettenträger abspringen können, da die Nocken der Bodenplatten der Raupenkette permanent mit den rundumlaufenden Nuten der Laufrollen in Eingriff sind.Accordingly, two laterally extending substantially over the length of the track carrier guide plates are arranged on the lower flange of the crawler carrier, which are engaged behind by arranged on the bottom plates of the caterpillar holding plates. This achieves in a simple manner that the caterpillars can not jump off the crawler support even in rough terrain, since the cams of the bottom plates of the crawler are permanently in engagement with the circumferential grooves of the rollers.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
Vorteilhaft können in an der Oberseite der Bodenplatten eingegossene Löcher abgekröpfte Schrauben eingesetzt und gehalten sein, die die Halteplatte an der Bodenplatte festlegen. Bei dieser Ausführungsform können die an der Oberseite der Bodenplatten eingegossenen Löcher, die für das Halten der Kerne während des Gussprozesses erforderlich sind, zur Montage von Halteplatten genutzt werden. Vorzugsweise sind zwei abgekröpfte Schrauben über einen Quersteg miteinander verbunden, über den sich die in die Bodenplatten eingeführten Schrauben auf dieser abstützen. Die auf diese Schrauben aufsteckbaren Halteplatten können beispielsweise über zwei Schraubenmuttern fest mit der Bodenplatte verbunden sein. Um eine genügend hohe Festigkeit aufzuweisen, können die Halteplatten beispielsweise als Gussteil gefertigt sein. Die Halteplatten können vorteilhaft trapezförmig sein und aufgrund dieser Formgestaltung können sie Verschmutzungen nach außen ableiten. Erfindungsgemäß betrifft die Erfindung auch eine Raupenkette für ein Fahrwerk sowie einen Raupenkran mit einem erfindungsgemäßen Fahrwerk.Advantageously, in the cast-in at the top of the bottom plates holes bent screws can be used and held, which define the retaining plate on the bottom plate. In this embodiment, the holes cast in the top of the bottom plates, which are required for holding the cores during the casting process, can be used to mount retaining plates. Preferably, two cranked screws are connected to one another via a transverse web, over which the screws introduced into the base plates are supported on this. The attachable to these screws holding plates can be firmly connected, for example, two nuts with the bottom plate. In order to have a sufficiently high strength, the holding plates can be made for example as a casting. The retaining plates may advantageously be trapezoidal and due to this design, they can derive dirt to the outside. According to the invention, the invention also relates to a crawler for a chassis and a crawler crane with a chassis according to the invention.
Ein weiterer Vorteil der Erfindung besteht darin, dass die Kette beim Transport nicht mehr durchhängt. Damit kann das Mittelstück bei seiner Verbolzung wesentlich niedriger aufgebockt werden.Another advantage of the invention is that the chain no longer sags during transport. Thus, the middle piece can be jacked much lower in his Verbolzung.
Schließlich kann das Verladen eines mit dem erfindungsgemäßen Fahrwerk ausgestatteten Raupenkrans auf einem Tieflader wesentlich verbessert werden. Bislang war es nötig, dass das untere Kettentrum der Raupenkette mit eigens dafür vorgesehenen Ketten fixiert wird. Dieses zusätzliche Herumlegen von Ketten um das untere Kettentrum kann beim Verladen zukünftig entfallen.Finally, the loading of a crawler crane equipped with the landing gear according to the invention can be substantially improved on a low loader. So far, it was necessary that the lower chain of the track chain is fixed with specially designated chains. This additional laying around of chains around the lower chain center can be dispensed with during loading in the future.
