Abstract

The towbar coupling includes a hook (12) with a ball (10), a socket (14) of a trailer and a lock (28) to retain the ball in the socket. A bumper assembly fixed to the trailer near the socket includes a support (16), extending forward fo the socket. A impact plate (18) is attached to the support at right angles to the direction of travel. The impact plate pref. includes a U-shaped recess (26) to guide the ball into the socket. ADVANTAGE - No risk of damage to the towing vehicle.

Description

Die Erfindung betrifft eine Zugkugelkupplung.The invention relates to a ball coupling.

Zugkugelkupplungen dienen zum Ankuppeln eines Anhängers an die Deichsel eines Zugfahrzeugs. Zu diesem Zweck sind Zugkugelkupplungen mit einer zur Aufnahme der Kugel einer Zugdeichsel dienenden Kugelpfanne und einer Einrichtung zum Verriegeln der Kugel in der Kugelpfanne versehen.Drawbar ball couplings are used to couple a trailer to the drawbar of a towing vehicle. For this purpose Ball couplings with one for receiving the ball one Drawbar serving ball socket and a device provided for locking the ball in the ball socket.

Häufig wird die Rückpartie des Zugfahrzeugs durch das vordere, ungeschützte Ende der Zugkugelkupplung beschädigt: Wenn der Anhänger beispielsweise von Hand in Richtung auf das Zugfahrzeug gezogen wird, um die Zugkugelkupplung mit der Zugdeichsel zu verbinden, gelingt es häufig nicht, den Anhänger rechtzeitig zu bremsen, so daß das freie Ende der Zugkugelkupplung gegen die rückwärtige Partie des Zugfahrzeugs anschlägt. Entsprechend kann die Rückpartie des Zugfahrzeugs beschädigt werden, wenn der Fahrer des Zugfahrzeugs zum Ankuppeln zurücksetzt und nicht rechtzeitig bremst.Often the back of the towing vehicle is Front, unprotected end of the ball coupling damaged: For example, if the trailer is moved by hand towards is pulled onto the towing vehicle, around the towing ball coupling It can be connected with the drawbar often not to brake the trailer in time, so that the free end of the ball coupling against the rear Batch of the towing vehicle strikes. Corresponding  the rear of the towing vehicle can be damaged, when the driver of the towing vehicle resets to couple and does not brake in time.

Der Erfindung liegt die Aufgabe zugrunde, eine Zugkugelkupplung zu schaffen, bei derartige Beschädigungen des Zugfahrzeugs vermieden werden können.The invention has for its object a ball coupling to create such damage to the Towing vehicle can be avoided.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine sich beidseitig längs der Zugdeichsel über deren freies Ende hinaus erstreckendes, an der Zugdeichsel im Bereich der Kugelpfanne angesetztes Haltelement, und ein auf das Haltelement aufgesetztes, sich quer zur Zugdeichsel erstreckendes Prallelement.According to the invention, this object is achieved by on both sides along the drawbar over their free End extending out at the drawbar in the area the ball socket attached retaining element, and one on the Holding element attached, extending transversely to the drawbar Impact element.

Dabei wird vorgeschlagen, daß das Haltelement aus einem Stahlblech mit einer das Prallelement aufnehmenden Basis und zwei auf die Kugelpfanne zulaufende Schenkel gebildet ist.It is proposed that the holding element from a Sheet steel with a base receiving the impact element and formed two legs running towards the ball socket is.

Eine bevorzugte Ausführungsform zeichnet sich dadurch aus, daß das Prallelement aus einem gummiartigen Material besteht.A preferred embodiment is characterized by this from that the baffle element made of a rubber-like material consists.

Weiter wird vorgeschlagen, daß das Prallelement mit einer U-förmigen Ausnehmung zum Durchführen der Zugdeichsel versehen ist.It is also proposed that the impact element with a U-shaped recess for carrying out the drawbar is provided.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The invention is described below with reference to a drawing explained. It shows:

Fig. 1 eine Seitenansicht auf die Zugkugelkupplung, Fig. 1 is a side view of the coupling head,

Fig. 2 eine Fig. 1 entsprechende Draufsicht, und Fig. 2 is a plan view corresponding to Fig. 1, and

Fig. 3 eine Frontansicht auf das Prallelement. Fig. 3 is a front view of the impact element.

Die Zugkugelkupplung ist mit einer Kugelpfanne 14 und einer Einrichtung zum Verriegeln der (nur gestrichelt dargestellten) Kugel 10 der Zugdeichsel 12 eines Zugfahrzeugs und einer Einrichtung zum Verriegeln der Kugel 10 in der Kugelpfanne 14 versehen, wobei diese Einrichtung mit einem Verriegelungshebel 28 versehen ist. Die Zugkupplung ist über Befestigungsbolzen 30 an dem Zugrohr 32 des Anhängers befestigt.The ball coupling is provided with a ball socket 14 and a device for locking the ball 10 (only shown in broken lines) of the drawbar 12 of a towing vehicle and a device for locking the ball 10 in the ball socket 14 , this device being provided with a locking lever 28 . The pull coupling is fastened to the draw tube 32 of the trailer via fastening bolts 30 .

Die Zugkugelkupplung ist mit einem Rammschutz versehen, der aus einem Haltelement 16 und einem Prallelement 18 besteht. Das Haltelement ist dabei ein Stahlblech mit einer das Prallelement 18 aufnehmenden Basis 20 und zwei auf die Kugelpfanne 14 zulaufende Schenkel 22, 24. Die Schenkel 22, 24 sind dabei im Bereich der Kugelpfanne 14 mit der Zugkugelkupplung durch Verschweißen, Vernieten oder Verschrauben befestigt.The ball coupling is provided with a ram protection, which consists of a holding element 16 and an impact element 18 . The holding element is a steel sheet with a base 20 receiving the impact element 18 and two legs 22 , 24 running towards the ball socket 14 . The legs 22 , 24 are fastened in the region of the ball socket 14 to the ball coupling by welding, riveting or screwing.

Auf die Basis 20 des Haltelements 16 ist ein aus einem gummiartigen Material bestehendes Prallelement 18 aufgesetzt.A baffle element 18 made of a rubber-like material is placed on the base 20 of the holding element 16 .

Fig. 3 verdeutlicht, daß das Prallelement mit einer U-förmigen Ausnehmung 26 versehen ist, die zum Durchführen der Zugdeichsel 12 dient. Fig. 3 illustrates that the impact element is provided with a U-shaped recess 26 which is used to carry out the drawbar 12 .

Bei der hier vorgeschlagenen Zugkugelkupplung wird die Beschädigung des Zugfahrzeugs bei Heranführen des Anhängers an das Zugfahrzeug zuverlässig vermieden, bei einem etwaigen Auftreffen der Zugkugelkupplung auf die Rückpartie des Zugfahrzeugs wird der Stoß von dem Rammschutz aufgefangen.In the ball coupling proposed here, the Damage to the towing vehicle when the trailer is brought up to the towing vehicle reliably avoided at one possible impact of the ball coupling on the rear part the impact of the towing vehicle is from the impact protection caught.

Bereits in Verwendung befindliche Zugkugelkupplungen können mit dem hier vorgeschlagenen Rammschutz einfach ergänzt werden.Ball couplings already in use can easily with the proposed crash protection be supplemented.
