Die in der Fig. 1 dargestellte Zugeinrichtung gemäss dem Stand der Technik weist einen Zugarm 1 auf, an dessen nicht ersichtlichem vorderen Ende ein Zughaken angeordnet ist. Der Zugarm 1 ist mittels eines gesicherten Bolzens 2 mit dem Gabelkopf 3 verbunden. Letzterer geht in die einstückig mit ihm geformte eigentliche Zugstange 4 über. Sowohl der Gabelkopf 3 wie auch die Zugstange 4 werden in einer Abstützung 5 geführt. Koaxial um die Zugstange 4 herum sind die aus elastomerem Kunststoff bestehenden Federelemente 6 angeordnet, welche unter sich durch Zwischenscheiben 7 getrennt sind. Die Federelemente 6 stützen sich in Zugrichtung ab auf die Abstützung 5, in Gegenrichtung, also fahrzeugseitig, auf eine Druckplatte 8. Die Druckplatte 8 ist am fahrzeugseitigen Ende der Zugstange 4 mittels einer Kronenmutter 9 gesichert, welch letztere ihrerseits durch einen Splint 10 gesichert ist. Die Abstützung 5 liegt in Zugrichtung an auf seitlich angeordneten Zuganschlägen (nicht dargestellt); in Gegenrichtung wird sie normalerweise nicht belastet. Gehalten wird die Abstützung mittels 4 Schrauben, welche die Grundplatte der Abstützung mit den Längsträgern des Fahrzeuges verbinden jedoch nicht näher dargestellt sind.The traction device shown in FIG. 1 according to the prior art a pull arm 1, at the front end, not shown, a pull hook is arranged is. The pull arm 1 is by means of a secured bolt 2 with the fork head 3 connected. The latter goes into the actual tie rod formed in one piece with it 4 over. Both the clevis 3 and the tie rod 4 are in one Support 5 out. Coaxial around the tie rod 4 are made of elastomer Plastic existing spring elements 6 arranged, which under themselves by washers 7 are separated. The spring elements 6 are supported in the pulling direction on the support 5, in the opposite direction, that is to say on the vehicle side, on a pressure plate 8. The pressure plate 8 is at the vehicle end of the tie rod 4 by means of a crown nut 9 secured, the latter in turn secured by a split pin 10. The support 5 lies in the direction of pull on laterally arranged pull stops (not shown); it is normally not loaded in the opposite direction. Held the support is attached using 4 screws that attach the base plate to the support connect the side members of the vehicle are not shown.

In der Fig. 2 wird eine beispielhafte Ausführungsform der erfindungsgemässen Zugeinrichtung dargestellt, wobei gleiche Teile gleiche Bezugszeichen tragen und im wesentlichen nur auf die Unterschiede zu der Ausbildungsform gemäss Fig. 1 näher eingegangen wird. Bei der erfindungsgemässen Ausführungsform wird die Zugstange 11 durch eine mit einem Kopf 13 versehene Schraube 12 gebildet, welche endseitig mit einem Aussengewinde 14a versehen ist und bei 14 in den mit einem Innengewinde 14b versehenen Gabelkopf 3 eingeschraubt ist. Als Gewinde 14a, 14b haben sich gerollte Gewinde, beispielsweise in der Dimension M60x2, als besonders vorteilhaft erwiesen. Der Schraubenkopf 13 dient gleichzeitig als Anschlag für die Druckplatte 8. Die Montage erfolgt in analoger Weise wie bei der beschriebenen Zugeinrichtung nach dem Stand der Technik indem die Federelemente 6 stark zusammengepresst werden, während die Schraube 12 eingedreht wird. Die Gewindeverbindung 14 wird einerseits durch Anschläge am Druckteller 8, welche auf den Kopf 13 der Schraube 11 wirken, und anderseits durch eine mechanische Sicherung gesichert. Die mechanische Sicherung der eingeschraubten Zugstange 11 wird durch einen zweiteiligen Sicherungsring 16 gebildet, der in einer Nut 17 der Zugstange 11 aufgenommen ist. Der Gabelkopf 3 seinerseits ist im Bereich des zugseitigen Endes der Zugstange 11 mit einem die Zugstange 11 umgebenden hohlzylindrischen Abschnitt 18 versehen, dessen Innendurchmesser zumindest annähernd dem Aussendurchmesser des Sicherungsrings 16 entspricht. Dadurch wird sichergestellt, dass der Sicherungsring 16 nicht aus der Nut 17 herausspringen kann. An den genannten hohlzylindrischen Abschnitt 18 schliesst sich ein Abschnitt 19 an, der einen grösseren Innendurchmesser bzw. eine grössere Öffnungsweite als der hohlzylindrische Abschnitt 18 aufweist. Um den Sicherungsring 16 in der Nut 17 fixieren zu können, wird die Zugstange 11 mit ihrem zugseitigen Ende entgegen der Vorspannkraft der Federelemente 6 soweit in den Abschnitt 19 hineingeschraubt, dass der Sicherungsring 16 über den Abschnitt 19 eingeführt und über den zwischen Zugstange 11 und Abschnitt 19 verbleibenden Zwischenraum in die Nut 17 eingesetzt werden kann. Danach wird die Zugstange 11 wieder soweit zurückgedreht, bis sich der Sicherungsring 16 am hinteren Ende des hohlzylindrischen Abschnitts 18 anlegt. Eine derartige Sicherung hat den grossen Vorteil, das deren Vorhandensein, im Gegensatz beispielsweise zu einem selbsthärtenden Bindemittel, visuell überprüft werden kann, wobei damit keinesfalls ausgeschlossen werden soll, dass für bestimmte Anwendungsfälle ein selbsthärtendes Bindemittel zur Sicherung der Zugstange 11 vorgesehen werden kann.2 shows an exemplary embodiment of the traction device according to the invention shown, the same parts bearing the same reference numerals and essentially only in more detail on the differences to the training form according to FIG. 1 is received. In the embodiment according to the invention, the pull rod 11 formed by a screw 12 provided with a head 13, which is provided at the end with an external thread 14a and at 14 in the with a Internal thread 14b provided fork head 3 is screwed. As thread 14a, 14b rolled threads, for example in the dimension M60x2, are special proven advantageous. The screw head 13 also serves as a stop for the Pressure plate 8. The assembly is carried out in an analogous manner to that described Towing device according to the prior art by the spring elements 6 strongly pressed together be while the screw 12 is screwed in. The threaded connection 14 is on the one hand by stops on the pressure plate 8, which on the Head 13 of the screw 11 act, and on the other hand by a mechanical lock secured. The mechanical securing of the screwed-in tie rod 11 is performed by a two-part locking ring 16 formed in a groove 17 of the tie rod 11 is recorded. The fork head 3 in turn is in the area of the train end the pull rod 11 with a hollow cylindrical portion surrounding the pull rod 11 18 provided, the inside diameter of which is at least approximately the outside diameter the locking ring 16 corresponds. This ensures that the locking ring 16 cannot jump out of the groove 17. On the above hollow cylindrical section 18 is followed by a section 19 which is a larger one Inner diameter or a larger opening width than the hollow cylindrical Section 18 has. In order to be able to fix the circlip 16 in the groove 17, the pull rod 11 with its pull end against the biasing force of the Spring elements 6 screwed so far into section 19 that the locking ring 16 introduced via the section 19 and the between the tie rod 11 and Section 19 remaining space can be inserted into the groove 17. Then the pull rod 11 is turned back until the locking ring 16 creates at the rear end of the hollow cylindrical portion 18. Such Fuse has the great advantage that its existence, in contrast, for example to a self-curing binder, can be checked visually, whereby this is by no means to be ruled out for certain applications a self-curing binder is provided to secure the pull rod 11 can be.

Das gezeigte Ausführungsbeispiel einer Zugeinrichtung kann schnell, einfach und kostengünstig gefertigt werden. Zudem können, im Gegensatz zu einer einteiligen Zugstange, die Zugschraube 11 oder der Gabelkopf 3 ggf. einzeln ersetzt und/oder aus unterschiedlichen Materialien gefertigt werden.The illustrated embodiment of a traction device can be quick, simple and can be manufactured inexpensively. In addition, unlike a one-piece Tension rod, the tension screw 11 or the clevis 3 possibly replaced individually and / or be made from different materials.
