Description

In Transportbetrieben, vorwiegend in landwirtschaftlichen Betrieben, ereignen sich viele Unfälle dadurch, daß die Anhänger mit ungenügenden Bremseinrichtungen versehen sind. Die verschiedenen Bremseinrichtungen bekannter Ausführungen bedingen stets eine zweite Person, die die Betätigung vornimmt. Da diese Person. in derRegel im Kraftfahrzeugfüh.ren nicht ausgebildet ist und auch sehr oft keine Übersicht über die Fahrbahn hat, sind Unfälle während der Fahrt sehr häufig. Aber auch beim Rangieren von Hand ereignen sich sehr viele Unfälle, weil die an der Lenkdeichseil tätige Person den Anhänger nicht bremsen kann. Auch bei Verwendung einer der bekannten Auflauf- und Fallbremsen ist dies nur möglich, wenn die die Lenkdeichsel haltende Person die Lenkdeichsel fast bis in Bodennähe bringt, um eine Bremswirkung durch die Fallbremse zu erzielen. Auch beim Ankuppeln des Anhängers an das Kraftfahrzeug (Schlepper) ist stets eine zweite Person oder eine zusätzliche Einrichtung notwendig, um das Zuggabelauge der Lenkdeichsel in die erforderliche Höhe der Anhängekupplung zu bringen. Auch hierbei -ereignen sich Unfälle der mannigfachsten Art.In transport companies, mainly in agricultural operations, Many accidents occur because the trailer has inadequate braking devices are provided. The various braking devices of known designs require always a second person to do the work. Because that person. usually is not trained in driving a motor vehicle and very often no overview over the road, accidents while driving are very common. But also with Maneuvering by hand, there are a lot of accidents because those on the steering drawbar rope active person cannot brake the trailer. Even when using one of the well-known Overrun and fall brakes are only possible if the person holding the steering drawbar Person brings the steering drawbar almost to the ground in order to have a braking effect to achieve the fall brake. Even when coupling the trailer to the motor vehicle (Tractor) a second person or additional equipment is always necessary around the drawbar eye of the steering drawbar to the required height of the trailer coupling bring to. Here, too, accidents of the most varied kinds can occur.

Vorgenannte Mängel zu beseitigen und .eine bedeutend größere Unfallsicherheit im Verkehr zu erreichen, ist das Ziel der Erfindung.Eliminate the aforementioned deficiencies and. A significantly greater accident safety To achieve in traffic is the aim of the invention.

Die Bremse gemäß der Erfindung ist eine Hand-und Fallbremse. Sie kann sowohl vom Boden als auch vom Kraftfahrzeugsitz (Schleppersitz) aus bedient werden. Die Bremseinrichtung ermöglicht es. gleichzeitig, durch Betätigung des Bremshebels die Lenkdeichsel und damit das Zuggabelauge in jede erforderliche Höhe zu bringen und zu halten, ohne daß die Lenkdeichsel gesondert angehoben werden muß. Da die Betätigung der Bremseinrichtung vom Schlepperf,ü:hrersitz aus vorgenommen werden kann, kann somit der Schlepperführer allein und ohne fremde Hilfe den Anhänger ab- und ankuppeln. Dieses Ab- und Ankuppeln des Anhängers' kann auch in unebenem Gelände genau so vorgenommen werden. Solange.die Lenkdeichsel nicht unterstützt ist oder artgehoben wird, wirkt= =sie infolge ihres Eigengewichts als Fallbremse, ganz gleich, in welcher Höhe sich das Zuggabelauge der Lenkdeichsel. befindet. Auch während der Betätigung des Handhebels bei nicht angekuppeltem Anhänger bleibt die Wirkung der Fallbremse erhalten. Diese Vorteile wirken sich besonders günstig beim Rangieren des Anhängers von Hand aus. Die die Lenkdeichsel haltende Person kann in aufrechter Hal.tuhg :durch ein leichtes Anheben der Lenkdeichsel die Fallbremse außer Wirkung bringen und durch ein kurzes Absenken der Lenkdeichsel den Anhänger wieder bremsen.The brake according to the invention is a hand and fall brake. she can can be operated from the floor as well as from the vehicle seat (tractor seat). The braking device makes it possible. at the same time, by pressing the brake lever to bring the steering drawbar and thus the drawbar eye to any required height and to hold without the steering drawbar having to be raised separately. Since the Actuation of the braking device can be carried out from the tractor seat can, the tractor driver can unload the trailer alone and without outside help. and couple. This uncoupling and coupling of the trailer can also be carried out on uneven terrain be done exactly the same way. As long as the steering drawbar is not supported or is lifted, acts = = due to its own weight as a fall brake, regardless of at what height is the drawbar eye of the steering drawbar. is located. Even during the Actuation of the hand lever when the trailer is not coupled remains the effect of the Drop brake received. These advantages are particularly beneficial when maneuvering of the trailer by hand. The person holding the steering shaft can be in an upright position Hal.tuhg: the fall brake becomes ineffective by slightly lifting the steering drawbar and then brake the trailer again by briefly lowering the steering drawbar.

Es ist unverkennbar, daß dadurch ein hohes Maß von Unfallsicherheit erreicht wird.It is unmistakable that this creates a high level of accident safety is achieved.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in zwei verschiedenen Stellungen gezeigt, und zwar zeigt Abb. i eine Bremseinrichtung mit gesenkter -Deichsel und Abb. a die nämliche Bremseinrichtung mit angehobener Deichsel.In the drawing is an embodiment of the invention in two different positions shown, namely Fig. i shows a braking device with lowered drawbar and Fig. a the same braking device with raised drawbar.

i ist die Lenkdeichsel mit dem daran befestigten Zuggabelauge z, die im Punkt 3 am Anhänger vertikal schwenkbar befestigt ist. 4 ist die auf die Achsbremsen des Anhängers wirkende Druckstange, 5 der Bremshebel, welcher im Punkt 6 drehbar ist und am Segment.; gehalten und geführt wird. Das Segment 7 mit dem Drehpunkt 6 ist an der Lenkdeichsel i befestigt. Die Druckstange 4 ist vorn im Punkt 8 des Bremshebels 5 und hinten im Punkt 9 des Bremsgestänges angelenkt.i is the steering drawbar with the drawbar eye z attached to it, which is attached vertically pivotable at point 3 on the trailer. 4 is the push rod acting on the axle brakes of the trailer, 5 is the brake lever, which is rotatable at point 6 and on the segment .; is held and guided. The segment 7 with the pivot point 6 is attached to the steering drawbar i. The push rod 4 is hinged at the front at point 8 of the brake lever 5 and at the rear at point 9 of the brake linkage.
