Opfindelsen angår en påhængskobling til motorkøretøjer, navnlig til personautomobiler, og som har en til fastgørelse til bagenden af køretøjet på tværs af dettes længdeakse indrettet bærebom for en kuglehals roed koblingskugle .BACKGROUND OF THE INVENTION The invention relates to a trailer coupling for motor vehicles, in particular for passenger cars, and having a carrier beam arranged on the rear axle of the vehicle across the longitudinal axis of the red coupling ball of a ball neck.
Bærebomme til påhængskoblinger er hidtil blevet fremstillet af runde eller firkantede rør, der til optagelse af alle optrædende belastninger har en betydelig vægtykkelse på sædvanligvis 4-5 mm. Derved får påhængskoblingerne en forholdsvis stor vægt, hvilket er i modstrid med bilfabrikanternes bestræbelser på at konstruere køretøjerne så lette som muligt og kun at tillade ekstra udstyr, såsom påhængskoblinger, som ikke har væsentlig indflydelse på køretøjets totalvægt.Carrier bars for outboard couplings have so far been made of round or square tubes which have a considerable wall thickness of usually 4-5 mm to accommodate all occurring loads. This gives the couplings a relatively high weight, which is contrary to the vehicle manufacturers' efforts to design the vehicles as lightly as possible and to allow only extra equipment, such as couplings which do not significantly affect the total weight of the vehicle.
Det er næppe muligt at gøre kuglehalsen og koblingskuglen lettere, og formålet med opfindelsen er derfor at udforme bærebommen på en sådan måde, at den uden reduktion af styrken vejer væsentligt mindre end en sædvanlig bærebom,f.eks. kun halvt så meget som denne.It is hardly possible to make the ball neck and the coupling ball lighter, and therefore the object of the invention is to design the carrier boom in such a way that it weighs substantially less than a conventional carrier boom, without reducing the strength. only half as much as this one.
Denne opgave løses ifølge opfindelsen ved, at bære-bommen består af flere skåle af plademateriale dog fortrinsvis af to halvskåle, der er forsynede med flanger, og ved at disse flanger er forbundne med hinanden til en lukket bærebom ved hjælp af svejsning fortrinsvis punktsvejs-ning, og at skålene har forskellige pladetykkelser.This task is solved according to the invention in that the carrier boom consists of several bowls of sheet material, however preferably of two half bowls, which are provided with flanges, and in that these flanges are connected to one another by a closed support boom by means of welding, preferably spot welding. , and that the bowls have different plate thicknesses.
Ved hjælp af denne udformning opnås det at tilvejebringe en bærebom, der med en lille egenvægt er i stand til at optage alle belastninger, og som kan udformes på en sådan måde, at bøjnings- og torsionsspændingerne er tilnærmelsesvis lige store over hele bærebommens længde, idet der under stadig hensyntagen til de krav, der stilles til bærebommen, kun behøver anvendes tykkere plademateriale på steder, hvor dette er absolut påkrævet af hensyn til styrken.By means of this embodiment, it is obtained to provide a carrier boom which is capable of accommodating all loads with a small weight and which can be designed in such a way that the bending and torsional stresses are approximately equal over the entire length of the carrier boom, which, while still taking into account the requirements of the carrier boom, only thicker sheet material needs to be used in places where this is absolutely required for the sake of strength.
Dersom bærebommen skal anbringes inden for et køretøjs bageste kofanger opnås endvidere den fordel, at hele det rum, som kofangeren dækker, kan udnyttes til bærebommen, således at bærebommens plademateriale kan vælges 145335 2 tilsvarende tyndt. Desuden er det uden videre muligt ved indprægninger eller lignende at tilpasse bærebommens form efter køretøjets karosseri eller dele deraf.Further, if the carrier boom is to be positioned within the rear bumper of a vehicle, the advantage is obtained that the entire space covered by the bumper can be utilized for the carrier boom, so that the carrier material plate material can be selected as thin. In addition, it is possible to adjust the shape of the carrier boom according to the body of the vehicle or parts thereof by embossing or the like.
Den af skåle sammensatte bærebom kan over sin længde have forskellige tværsnit, således at tværsnitsarealet er størst ved fastgørelsesstedet for kuglehalsen med koblingskuglen. Også ved hjælp af denne foranstaltning, der ikke er mulig ved anvendelse af runde eller firkantede rør, kan bærebommen gøres lettere. Til samme formål kan bærebomskålene have huller eller lignende åbninger.The carrier composite beam may have different cross sections over its length, so that the cross-sectional area is greatest at the point of attachment of the ball neck with the coupling ball. Also, using this measure, which is not possible with the use of round or square pipes, the carrier boom can be made easier. For the same purpose, the carrier booms may have holes or similar openings.
Dersom påhængskoblingen skal dimensioneres til særligt store belastninger, kan der anbringes afstivningsplader i bommens indre.If the trailer coupling is to be designed for particularly high loads, stiffening plates can be placed in the interior of the boom.
Til fastgørelse af kuglehalsen kan bærebommen have en åbning, gennem hvilken kuglehalsen med sin fastgørelsesende er ført ind i bærebommen og f.eks. ved sammenskruning er forbundet med bærebommen.For fastening the ball neck, the carrier bar may have an opening through which the ball neck with its fastening end is inserted into the carrier bar and e.g. when screwed in, is connected to the carrier boom.
På tegningen er en udførelsesform for bærebommen ifølge opfindelsen anskueliggjort. På tegningen viser: fig. 1 en plantegning af en af to skåle bestående bærebom, fig. 2 et billede af den i figur 1 viste bærebom set i pilretningen II, fig. 3 et snit i større målestok gennem bærebommen efter linien III-III i fig. 2, fig. 4 et snit gennem bærebommen efter linien IV-IV i fig. 2, ogIn the drawing, an embodiment of the carrier boom according to the invention is illustrated. In the drawing: FIG. 1 is a plan view of one of two bowls of carrier beams; FIG. 2 is a view of the carrier boom shown in FIG. 1 in the direction of arrow II; FIG. 3 is an enlarged sectional view of the carrier boom along line III-III of FIG. 2, FIG. 4 is a section through the support bar along line IV-IV of FIG. 2, and
fig. 5 et snit gennem bærebommen efter linien V-VFIG. 5 is a section through the carrier boom along line V-V
i fig. 2 med antydet fastgørelse af kuglehalsen med koblingskuglen.in FIG. 2 with the indicated attachment of the ball neck with the coupling ball.
Den i fig. 1 og 2 viste bærebom 1 med en påhængskobling består af to pladeskåle 2 og 3, der er forsynede med flanger 4 og 5 og ved disse flanger er forbundne med hinanden ved hjælp af punktsvejsning. Pladeskålen 2, der vender mod køretøjets bageste ende og fastgøres til denne, har en mindre dybde end pladeskålen 3, der ved sit midterste område har den største dybde, og hvis dybde således aftager, hen mod begge dens ender.The FIG. 1 and 2, with a trailer coupling 1, consists of two plate bowls 2 and 3, which are provided with flanges 4 and 5, and by these flanges are connected to each other by means of spot welding. The plate bowl 2 facing the rear end of the vehicle and attached thereto has a smaller depth than the plate bowl 3, which at its middle region has the greatest depth, and whose depth thus decreases, towards both its ends.
145335 3145335 3
Som det ses i fig. 3, består pladeskålen 2 af et tykkere materiale end pladeskålen 3, Bærebommen l's ende-områder, ved hvilke den fastgøres til køretøjet, er som vist i fig. 4 forstærkede ved hjælp af indsvejste plader 7.As seen in FIG. 3, the plate bowl 2 consists of a thicker material than the plate bowl 3, the end regions of the carrier boom 1, to which it is attached to the vehicle, are as shown in FIG. 4 reinforced by welded plates 7.
Til fastholdelse af kuglehalsen 8 med koblingskuglen 9 har bærebommen 1 som vist i fig. 5 en åbning 10 i pladeskålen 3, gennem hvilken kuglehalsen 8 kan stikkes ind i bærebommen 1. Kuglehalsen 8 er fastgjort til bærebommen 1 ved hjælp af skruer 11, der indgriber med holdeorganer 12, som er fastsvejste til kuglehalsen.For holding the ball neck 8 with the coupling ball 9, the carrier boom 1 has as shown in FIG. 5 shows an opening 10 in the plate bowl 3 through which the ball neck 8 can be inserted into the support bar 1. The ball neck 8 is secured to the support bar 1 by means of screws 11 which engage with retaining means 12 which are welded to the ball neck.
