Description

Die Befestigung von Fahrzeuganhängern am Zugwagen geschieht meist mittels Kugelgelenke oder Spiralfedern. Diese haben den Nachteil, daß sie entweder die Stöße nicht genügend elastisch aufnehmen oder sich in kurzer Zeit derart abnutzen, daß toter Gang zwischen den Kupplungsteilen entsteht. Man hat bereits vorgeschlagen, derartige Kupplungen dadurch zu verbessern, daß man die Übertragung der Kräfte zwischen Zugwagen und Anhängerfahrzeug mittels eines in der Fahrtrichtung liegenden Luftgummireifens bewirkte. Dabei wurde der Luftgummireifen waagerecht angeordnet, so daß er zwar die Kräfte beim Anfahren und Bremsen einwandfrei aufnehmen konnte, für die Übertragung der .senkrechten Kräfte zwischen den beiden Fahrzeugen mußte jedoch ein besonderes Gestänge vorgesehen werden. Für dieses Gestänge gelten die gleichen Nachteile wie bei den Kupplungen, die mit Kugelgelenken oder Spiralfedern arbeiten.The attachment of vehicle trailers to the towing vehicle is usually done by means of ball joints or coil springs. These have the disadvantage that they either do not absorb the impacts sufficiently elastic or are in wear out in such a way that dead gear occurs between the clutch parts. Man has already proposed to improve such couplings by having the Transmission of the forces between the towing vehicle and the trailer vehicle by means of an in the Direction of travel lying pneumatic tire caused. The pneumatic tire was used arranged horizontally, so that he does the forces when starting and braking properly could absorb, for the transfer of the vertical forces between the two Vehicles, however, had to be provided with a special linkage. For this linkage The same disadvantages apply as with the couplings that have ball joints or Coil springs work.

Größere waagerechte Kräfte, die auf die Kupplungen wirken, sind nur beim Anfahren und Abbremsen vorhanden; während der Fahrt, also in dem normalen Betriebszustand, sind die Geschwindigkeitsdifferenzen zwischen Triebfahrzeug und Anhänger nur klein, so daß auch nur eine geringe Beanspruchung der Kupplung in waagerechter Richtung erfolgt. Dagegen tritt beim Fahren eine ständige große Beanspruchung der Kupplung durch senkrecht zur Fahrbahn gerichtete Kräfte dadurch ein, daß infolge von Schlaglöchern und Unebenheiten der Fahrbahn Zugwagen und Anhänger gegensätzliche, senkrechte Bewegungen ausführen.Larger horizontal forces that act on the clutches are only when starting and braking available; while driving, i.e. in the normal operating state, if the speed differences between the motor vehicle and the trailer are only small, see that there is also only a low level of stress on the coupling in the horizontal direction. On the other hand, when driving, there is a constant high stress on the coupling caused by perpendicular to the road Forces in that due to potholes and bumps in the road train carriages and followers make opposing, vertical movements.

Um nun den Luftgummireifen für die Aufnahme dieser im Normalbetrieb ständig auftretenden und unvermeidlichen Kräfte geeignet zu machen, wird erfindungsgemäß der Luftgummireifen senkrecht zur Fahrbahn angeordnet und mit einer äußeren und einer inneren Umrahmung versehen, an deren einer der Zugwagen und deren anderer der Anhänger befestigt ist. Zweckmäßig ist dabei die innere Umrahmung durch eine Gabelführung mit dem Zug- oder Anhängewagen verbunden.In order to now use the pneumatic tires for the inclusion of this constantly occurring in normal operation and to make unavoidable forces suitable, according to the invention the pneumatic rubber tire is arranged perpendicular to the roadway and provided with an outer and an inner frame, one of which is the towing vehicle and the other of which is the trailer is attached. The inner framing by means of a fork guide is useful here connected to the towing vehicle or trailer.

Ein Ausführungsbeispiel der erfindungsgemäßen Kupplung zeigt die Zeichnung. Der Luftgummireif en α ist mit einer äußeren und einer inneren Umrahmung b, b1 versehen, an deren einer der Zugwagen und deren anderer der Anhängewagen befestigt ist. Die innere Umrahmung b ist durch eine Gabelführung c mit dem Zug- oder Anhängewagen verbunden.The drawing shows an embodiment of the coupling according to the invention. The pneumatic rubber tire en α is provided with an outer and an inner frame b, b 1 , to one of which the towing vehicle and the other of which the trailer vehicle is attached. The inner frame b is connected to the towing or trailer carriage by a fork guide c.

Die erfindungsgemäße Kupplung hat keine Gelenk- und Schmierstellen, sie nimmt alle Stöße durch Luftfederung auf, so daß nicht nur die Kupplung selbst außerordentlich haltbar ist, sondern auch die Wagen, die unter keinen starken Stößen zu leiden haben, sehr geschont werden.The coupling according to the invention has no articulation or lubrication points, it takes them all Impacts by air suspension, so that not only the clutch itself is extremely durable is, but also the cars, which do not suffer from strong impacts be spared.
