Gemäß der Lehre der
Nachteilig an diesem Stand der Technik ist, dass die dort gelehrten scheibenförmigen Bremselemente relativ groß bauen, weswegen sie im Bereich zwischen den beiden Drehlagern angeordnet werden müssen, da nur dort genügend Bauhöhe zur Verfügung steht.A disadvantage of this prior art is that the disc-shaped brake elements taught there are relatively large, which is why they have to be arranged in the region between the two pivot bearings, since only there is sufficient overall height available.
Eine nicht gattungsgemäße Drehgelenkanordnung wird von der Firma Black Bruin verkauft. Diese Drehgelenkanordnung weist nur ein einziges Drehlager auf, mit zwei beabstandet voneinander angeordneten Laschen, die mit dem Kranarm verbunden sind (in Gebrauchslage obere Laschen) und einem zwischen den Laschen drehfest zu diesen angeordneten Lagerbolzen, an welchem die Befestigungsvorrichtung über eine Pendelöse pendelnd aufgehängt ist. Der Raum zwischen den beiden Laschen wird also vollständig vom Lagerbolzen und der entsprechenden Pendelöse ausgefüllt. Auf der Außenseite der Drehgelenkanordnung ist eine Pendelbremse befestigt, mit einer Mehrzahl von scheibenförmigen Bremselementen, von denen ein Teil an ihrem äußerem Umfangsrand eine Außenverzahnung und der andere Teil an ihrem inneren Umfangsrand eine Innenverzahnung aufweist. Der Lagerbolzen weist eine komplementäre Verzahnung auf, über welche jener Teil der scheibenförmigen Bremselemente, welcher eine Innenverzahnung aufweist, befestigbar ist. Der andere Teil der scheibenförmigen Bremselemente wird von einer an einem angebauten Ring angeordneten Innenverzahnung gehalten.A non-generic hinge assembly is sold by Black Bruin. This hinge assembly has only a single pivot bearing, with two spaced-apart tabs, which are connected to the crane arm (in the use position upper flaps) and a rotatably between the tabs arranged to these bearing pin on which the fastening device is suspended pendulum via a pendulum. The space between the two tabs is thus completely filled by the bearing pin and the corresponding shuttle. On the outer side of the hinge assembly is mounted a pendulum brake, with a plurality of disc-shaped brake elements, a part of which at its outer peripheral edge has an outer toothing and the other part at its inner peripheral edge has an internal toothing. The bearing pin has a complementary toothing, via which that part of the disk-shaped brake elements, which has an internal toothing, can be fastened. The other part of the disc-shaped brake elements is held by a mounted on an attached ring internal teeth.
Aufgabe der Erfindung ist es, eine gattungsgemäße Drehgelenkanordnung, einen Kran und ein Fahrzeug mit einem Kran derart weiterzubilden, dass die Pendelbremse einen geringeren Platzbedarf aufweist.The object of the invention is to develop a generic hinge assembly, a crane and a vehicle with a crane such that the pendulum brake has a smaller footprint.
Diese Aufgabe wird durch eine Drehgelenkanordnung mit den Merkmalen des Anspruchs 1, einen Kran mit einer solchen Drehgelenkanordnung und ein Fahrzeug mit einem solchen Kran gelöst.This object is achieved by a hinge assembly with the features of claim 1, a crane with such a hinge assembly and a vehicle with such a crane.
