Opfindelsen angår et anhængertræk til køretøjer, fortrinsvis til personautomobiler og bestående af et til køretøjet fastgjort bærerør, af en i bærerøret indskydelig kuglehals med en koblingskugle samt af løsbare gennemgående fastgørelsesorganer til fastholdelse af 5 kuglehalsen i bærerøret.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a trailer towing vehicle, preferably to passenger cars and consisting of a carrier tube attached to the vehicle, a ball neck slidable with a coupling ball and detachable through-going fasteners for holding the ball neck in the carrier tube.
Ved et f.eks. fra det tyske fremlæggelsesskrift nr.1.630.928 kendt anhængertræk af denne art består fastgørelsesorganerne af en excenterbolt, der kan betjenes ved hjælp af en arm og, når kuglehalsen er indsat i bærerøret, bevirker, at kuglehalsen spændes aksialt 10 mod bærerøret. Til udtagning af kuglehalsen af bærerøret skal excen-terbolten trækkes ud af kuglehalsen og af sine lejringer på hver side af bærerøret.In a e.g. From the German publication specification No. 1,630,928 known towing features of this kind, the fastening means consist of an eccentric bolt which can be operated by means of an arm and, when the ball neck is inserted into the support tube, causes the ball neck to be axially tensioned against the support tube. To remove the ball neck from the support tube, the eccentric bolt must be pulled out of the ball neck and from its bearings on each side of the support tube.
Formålet med opfindelsen er at tilvejebringe en fastgørelse, ved hvilken der, selv ved store toleranceforskelle mellem de med hin-15 anden samvirkende dele og uden nogen særlig finbearbejdning af disse, opnås en absolut slørfri fastspænding af kuglehalsen i bærerøret, og ved hvilken fastgørelsesorganerne er udformede på en sådan måde, at de til stadighed bliver siddende på den aftagelige kuglehals.The object of the invention is to provide a fastener, in which, even with large tolerance differences between the other cooperating parts and without any special machining thereof, an absolutely blur-free clamping of the ball neck in the carrier tube is achieved and at which the fastening means are formed. in such a way that they are constantly seated on the removable ball neck.
20 Denne opgave løses ifølge opfindelsen ved, at fastgørel sesorganerne består af en tapskrue, der strækker sig tværs gennem kuglehalsen og føres i et gevind i kuglehalsen, og med sin ene ende indgriber i en forsænkning i bærerørets indervæg og med sin anden ende føres i en boring i bærerøret. Herved opnås, at kuglehalsen i 25 bærerørets boring ved indskruet tapskrue trykkes mod den ene side af boringens væg, således at den nævnte slørfri forbindelse mellem bærerøret og kuglehalsen, der kan modstå alle optrædende belastninger, opnås, uden at kuglehalsen og bærerøret behøver være udformede med særlig stor nøjagtighed.This task is solved according to the invention in that the fastening means consist of a tapping screw which extends transversely through the ball neck and is inserted into a thread in the ball neck, with one end engaging a recess in the inner wall of the support tube and with its other end being inserted into a drilling in the carrier pipe. Hereby it is achieved that the ball neck in the bore of the carrier tube by means of screwed-in screw screw is pressed against one side of the wall of the bore, so that the said blur-free connection between the support tube and the ball neck, which can withstand all occurring loads, is obtained without the ball neck and the support tube having to be formed with particularly high accuracy.
30 Ifølge en fordelagtig udførelsesform for anordningen ifølge opfindelsen kan bærerøret have en slids for tapskruen, som ender i en boring, der tjener til optagelse af en på tapskruen udformet flange med større diameter. Herved opnås at kuglehalsen med derpå siddende fastgørelsesorganer kan indskydes i bærerøret, idet tapskruen indfø-35 res i bærerørets slids og ved helt indskudt kuglehals er optaget i boringen ved enden af slidsen.According to an advantageous embodiment of the device according to the invention, the support tube may have a slot for the tapping screw which ends in a bore which serves to receive a larger diameter flange formed on the tapping screw. Hereby it is achieved that the ball neck with attached fastening means can be inserted into the support tube, the tapping screw being inserted into the slot of the support tube and by fully inserted ball neck being accommodated in the bore at the end of the slot.
Tapskruen kan være sikret mod at falde ud af kuglehalsen ved hjælp af en sikringsstift, der ved aftagning af kuglehalsen begrænser tapskruens bevægelsesstrækning ved anslag.The tapping screw can be secured against falling out of the ball neck by means of a locking pin which, when removing the ball neck, limits the movement of the tapping screw upon impact.

En del af boringen til optagelse af flangen pi tapskruen kan være udformet i en forstærkningsplade på bærerøret, og tapskruen kan ved fastspændt kuglehals være sikret mod udskruning ved hjælp af en fjederklemme, der indgriber med en boring i forstærk-5 ningspladen og en ringnot pi tapskruens flange.Part of the bore for receiving the flange of the tapping screw may be formed in a reinforcing plate on the support tube, and the tapping screw may be secured against screwing by a spring clamp which engages with a bore in the reinforcing plate and a ring groove in the tapping screw. flange.
Tapskruen kan til betjening uden værktøj være forsynet med et betjeningshåndtag f.eks. et stjernehåndtag.For operation without tools, the tapping screw may be provided with an operating handle, e.g. a star handle.
På tegningen er en udførelsesform for et anhængertræk ifølge opfindelsen anskueliggjort. På tegningen viser: 10 Fig. 1 et sidebillede af et bærerør med indsat kugle hals, og fig. 2 et snit efter linien Il-Il i fig. 1.In the drawing, an embodiment of a towbar according to the invention is illustrated. In the drawing: FIG. 1 is a side view of a support tube with inserted ball neck, and FIG. 2 is a sectional view taken along the line II-II in FIG. First
Det i fig. 1 viste bærerør 1 rager bagud fra bagenden af et køretøj og tjener til løsbar fastgørelse af en i bærerøret indskudt 15 kuglehals 2 med en koblingskugle 3. Diameteren af boringen 4 i bærerøret 1 svarer til diameteren af kuglehalsen 2's indskudte del. Den forreste indføringsende af kuglehalsen er ligesom boringen 5 i bærerøret 1 aftrappet til en diameter, der er noget mindre end boringen 4's diameter, og ved indskudt kuglehals rager denne ind i boringen 5 20 med sin kugleformet udformede ende 6. En løsbar fastgørelse af kuglehalsen 2 i bærerøret 1 opnås ved hjælp af en tapskrue 7.The FIG. 1, the support tube 1 shown protrudes rearwardly from the rear of a vehicle and serves to releasably attach a ball neck 2 inserted in the support tube with a coupling ball 3. The diameter of the bore 4 in the support tube 1 corresponds to the diameter of the insertion portion of the ball neck 2. The leading insertion end of the ball neck, like the bore 5 of the support tube 1, is stepped to a diameter somewhat smaller than the diameter of the bore 4, and at the inserted ball neck, it projects into the bore 5 20 with its spherical shaped end 6. A detachable attachment of the ball neck 2 in the support tube 1 is obtained by means of a tapping screw 7.
Som det navnlig ses i fig. 2 strækker tapskruen 7 sig tværs gennem kuglehalsen 2 i en gevrndboring 8. Tapskruens forreste ende er forsynet med en kegleformet ansats 9, der indgriber med en 25 forsænkning 10 i bærerøret 1. Tapskruen 7 rager med sin modsatte ende ud gennem en boring 11 i bærerøret og er ved denne ende forsynet med et stjernehåndtag 12. Diameteren af boringen 11 er større end diameteren af tapskruen 7. En på tapskruen udformet krave 13, hvis diameter svarer til boringen 11's diameter, er optaget i boringen 30 11. En ved boringen 11 anbragt forstærkningsplade 14 forøger dybden af boringen 11. Flangen 13 er ved sin ydre omkreds udformet med en . ringnot 15, i hvilken en til sikring af tapskruen 7's stilling tjenende fjederklemme 16 indgriber, der er stukket ind i en boring 17 (fig. 1) i forstærkningspladen 14. En slids 18 (fig. 1), hvis bredde svarer til 35 diameteren af tapskruen 7 i dennes gevindområde, strækker sig fra enden af bærerøret 1 hen til boringen 11. En sikringsstift 19, der strækker sig vinkelret på tapskruen 7 og indgriber med en gevindfri og med mindre diameter udformet del af denne, sikrer tapskruen 7 mod udskruning af kuglehalsen 1.As seen in particular in FIG. 2, the tapping screw 7 extends transversely through the ball neck 2 in a threaded bore 8. The front end of the tapping screw is provided with a cone-shaped shoulder 9 which engages a recess 10 in the support tube 1. The tapping screw 7 protrudes through a bore 11 in the support tube. and is provided at this end with a star handle 12. The diameter of the bore 11 is larger than the diameter of the tapping screw 7. A collar 13 formed on the tapping screw, the diameter of which corresponds to the diameter of the bore 11, is accommodated in the bore 30 11. A positioned at the bore 11 reinforcing plate 14 increases the depth of bore 11. The flange 13 is formed at its outer circumference by a. ring groove 15, in which a spring clamp 16 serving to secure the position of the tapping screw 7 engages inserted into a bore 17 (Fig. 1) in the reinforcing plate 14. A slot 18 (Fig. 1) whose width corresponds to the diameter of the tapping screw 7 in its threaded region extends from the end of the support tube 1 to the bore 11. A locking pin 19 which extends perpendicular to the tapping screw 7 and engages a threadless and smaller diameter portion thereof, secures the tapping screw 7 against screwing of the ball neck first
3 T49712 Når kuglehalsen 2 er fastgjort til bærerøret 1, indtager alle dele den på tegningen viste stilling. Tapskruen 7 spænder kuglehalsen 2 i pilretningen 20 mod bærerøret 1. Der er dermed opnået en slørfri fastgørelse, som kan modstå alle optrædende belastninger.3 T49712 When the ball neck 2 is attached to the support tube 1, all parts occupy the position shown in the drawing. The tapping screw 7 tightens the ball neck 2 in the direction of the arrow 20 towards the support tube 1. A veil-free attachment is thus obtained, which can withstand all occurring loads.
5 Til kuglehalsen 2's udtagning af bærerøret 1 fjernes fjeder klemmen 16, og derefter skrues tapskruen 7 ved hjælp af stjernehåndtaget 12 så langt ud af kuglehalsen 2, at yderligere skruebevægelse standses som følge af, at tapskruen 7's gevind kommer til anslag mod sikringsstiften 19. Ved denne stilling af tapskruen 7 er dennes keg-10 leformede ansats 9 frigjort fra forsænkningen 10 i bærerøret 1, og flangen 13 er bevæget ud af boringen 11. I denne stilling af tapskruen 7 kan kuglehalsen 2 trækkes ud af bærerøret 1, hvorunder tapskruen 7 glider mellem slidsen 18's vægge.5 For the removal of the ball neck 2 from the support tube 1, the spring clamp 16 is removed, and then the tapping screw 7 is removed by means of the star handle 12 so far out of the ball neck 2 that further screw movement is stopped as the thread of the tapping screw 7 comes into contact with the locking pin 19. in this position of the tapping screw 7, its cone-shaped abutment 9 is released from the recess 10 in the support tube 1 and the flange 13 is moved out of the bore 11. In this position of the tapping screw 7 the ball neck 2 can be pulled out of the support tube 1, under which the tapping screw 7 slides. between the walls of the slot 18.
