Description

455 180 I figur l är en draganordning 3 anbringad mellan en icke visad personbils bakände 1 och den bakersta kofångaren 2, vilken draganordning består av en upptagningsdel 4 som är fast förbunden med fordonet och ett vid upptagningsdelen lösbart fäst kulskaft 5 med en kopplingskula 6. Upptagnings- delen 4 består av en tvärbalk 7 med en rörstuds B som är nedåtskjutande anbringad i fordonets längsgående mittplan och två hållarskenor 9 som är anbringade på var sin sida om rörstudsen 8 och som sträcker sig nedåt och bakåt. Kulskaftet 5 är ungefärligen lJ-format. Kulskaftets insticksände 10, som är insatt i rörstudsen 6, är försedd med en kulliknande del ll som tas upp i rörstudsen 8 utan spel. En nedåtgående fästskena 12 med ett hål 13 är anbringad mellan insticksänden 10 och kopplingskulan 6 på kulskaftets 5 ungefärligen vågräta del. Hålet 13 ligger i linje med motsvarande hål i hållarskenorna 9, så att kulskaftet 5 på avstånd från insticksänden lÜ kan spännas fast vid upptagningsdelen 4 med hjälp av en skruv 14. För att ta av kulskaftet 5 med kopplingskulan 6 är det bara nödvändigt att lossa skruven 14 och dra ut kulskaftet ur rörstudsen 8. In figure 1 a towing device 3 is arranged between the rear end 1 of a car (not shown) and the rear bumper 2, which towing device consists of a receiving part 4 which is fixedly connected to the vehicle and a ball shaft 5 releasably attached to the receiving part with a coupling ball 6. - the part 4 consists of a cross beam 7 with a pipe stub B which is slidably mounted in the longitudinal central plane of the vehicle and two retaining rails 9 which are arranged on each side of the pipe stub 8 and which extend downwards and backwards. The ball shaft 5 is approximately IJ-shaped. The insertion end 10 of the ball shaft, which is inserted in the pipe connection 6, is provided with a ball-like part 11 which is received in the pipe connection 8 without play. A downwardly fastening rail 12 with a hole 13 is arranged between the insertion end 10 and the coupling ball 6 on the approximately horizontal part of the ball shaft 5. The hole 13 is in line with the corresponding holes in the holding rails 9, so that the ball shaft 5 at a distance from the insertion end 10 can be clamped to the receiving part 4 by means of a screw 14. To remove the ball shaft 5 with the coupling ball 6, it is only necessary to loosen the screw 14 and pull the ball shaft out of the pipe socket 8.

Med ett kulskaft av den i fig. l visade formen kan fästskenan 12 också vara anbringad på ett annat ställe på kulskaftet, t.ex. på dettas i riktning mot insticksänden uppåtgående del om konstruktionen av fordonets bakände tillåter detta.With a ball shaft of the shape shown in Fig. 1, the mounting rail 12 can also be mounted at another place on the ball shaft, e.g. on this in the direction of the insertion end upward part if the construction of the rear end of the vehicle allows this.

Om kulskaftet är utformat på ett sådant sätt att det skall skjutas in i vågrät riktning i en på motsvarande sätt belägen upptagningsdel 4 så kan fästskenan 12 med fördel vara anbringad på kulskaftets vågräta del och sträcka sig nedåt från denna. Med ett snett nedåt löpande kulskaft kan fästskenan 12 sitta på kulskaftets uppåtvända sida där den är lätt tillgänglig för skruvens 14 insättning eller uttagning.If the ball shaft is designed in such a way that it is to be pushed in a horizontal direction in a correspondingly located receiving part 4, the fastening rail 12 can advantageously be mounted on the horizontal part of the ball shaft and extend downwards therefrom. With an obliquely downwardly extending ball shaft, the mounting rail 12 can sit on the upwardly facing side of the ball shaft where it is easily accessible for insertion or removal of the screw 14.

Enligt figur 2 är den kulliknande delen på kulskaftets 5 insticks- ände utformad som en kula 15 som är svetsad på kulskaftet. I figur 3 utgörs den kulliknande delen ll av själva kulskaftet 5, som är bearbetat på lämpligt sätt.According to Figure 2, the ball-like part on the insertion end of the ball shaft 5 is formed as a ball 15 which is welded to the ball shaft. In Figure 3, the ball-like part 11 is constituted by the ball shaft 5 itself, which is machined in a suitable manner.

Figurerna 4 till 6 visar att den kulliknande delen på kulskaftets 5 insticksände också kan bildas av plåtdelar 16 som är sammansvetsade med kulskaftet.Figures 4 to 6 show that the ball-like part on the insertion end of the ball shaft 5 can also be formed by sheet metal parts 16 which are welded together with the ball shaft.

I stället för den i figur l visade fästskenan 12 med hålet 13 kan kulskaftet 5 också vara försett med ett hål 17 som visas i figur 7. Enligt figur 8 är det också möjligt att svetsa ett öga 18 med ett hål 19 på kulskaftet 5 för att säkert fästa kulskaftet med en skruv.Instead of the fastening rail 12 shown in figure 1 with the hole 13, the ball shaft 5 can also be provided with a hole 17 as shown in figure 7. According to figure 8 it is also possible to weld an eye 18 with a hole 19 on the ball shaft 5 to securely fasten the ball shaft with a screw.
