Description
"Sykkel" "Bicycle"
Foreliggende oppfinnelse angår en to-hjuls sykkel med ramme og/eller gaffel av lettmetallprofiler., som er forbundet med hverandre ved hjelp av muffer. Kjente, vanlige sykler en forhjulsgaffel, en hovedramme og en bakhjulsramme, er frem-stilt av sømløse stålrør<q>g forbindelsesmuffer, i hvilke stålrørene er slagloddet. Til tross for små dimensjoner for stålrørene, i størrelsen 24 - 26 mm diameter, oppviser disse sykler en relativt høy vekt, og er utsatt for rustangrep. Dessuten er det kjent en konstruksjon der det anvendes muffer og rør av lettmetall og med omtrent de samme yttermål. Etter som slaglodding av lettmetall er utelukket av fasthets- og korrosjonstékniske grunner, blir rørene skrudd inn i muffene med fingjenger. For i .en viss grad å kompensere for kjerv-virkningen av gjengene, må disse'rør i området ved sammen-føyningsstedene forsterkes med innskjøvne rørhylser, hvilket betyr en øking av fremstillingsomkostningene og en vektøking. Dessuten har disse syklene ikke den nødvendige stivhet, slik The present invention relates to a two-wheeled bicycle with a frame and/or fork made of light metal profiles, which are connected to each other by means of sleeves. Known, common bicycles, a front wheel fork, a main frame and a rear wheel frame, are made of seamless steel tubes<q>g connecting sleeves, in which the steel tubes are butt-welded. Despite the small dimensions of the steel tubes, in the size 24 - 26 mm diameter, these bikes have a relatively high weight, and are prone to rust attack. In addition, a construction is known in which sockets and pipes made of light metal and with approximately the same external dimensions are used. Since impact soldering of light metal is excluded for technical reasons of strength and corrosion, the pipes are screwed into the sleeves with fine threads. In order to compensate to some extent for the notching effect of the threads, these pipes in the area at the joining points must be reinforced with pushed-in pipe sleeves, which means an increase in manufacturing costs and an increase in weight. Also, these bikes don't have the necessary stiffness, like that
som stålkonstruksjonen, slik at forbindelsene kan løsne like the steel structure, so that the connections can loosen
under belastning.under load.
I henhold til den foreliggende oppfinnelse unngås disse ulem^-per ved at hulprofilene er forbundet med muffene utelukkende ved hjelp av en tokomponent-klebeharpiks, og at hulprofilene i yttermål ligger over det vanlige. Ved anvendelse av et According to the present invention, these disadvantages are avoided by the fact that the hollow profiles are connected to the sleeves exclusively by means of a two-component adhesive resin, and that the outer dimensions of the hollow profiles are larger than usual. When using a
høyverdig klebémiddel, oppnås en arbeidsbesparende forbindelse high-quality adhesive, a labour-saving connection is achieved
med lav vekt, og som tåler alle de opptredende påkjenninger når klebeflåtene hår et visst, minstemål, pg .på grunn av de økede yttermål oppnås en stivnet som ligger nær opp til stivheten for en'sykkel av stål, hvorved sykkelen på grunn av.den mindre spesifikke vekt og veggtykkelse, er vesentlig lettere. ■'. with a low weight, and which withstands all the stresses that occur when the adhesive rafts have a certain, minimum size, because of the increased outer dimensions, a stiffened mesh is achieved that is close to the stiffness of a steel bicycle, whereby the bicycle due to less specific weight and wall thickness, is significantly lighter. ■'.
Oppfinnelsen er på tegningene vist ved et utførelseseksempel. The invention is shown in the drawings by an exemplary embodiment.
Fig. 1 viser hovedrammen og bakhjulsrammen, mens fig. 2 viser en forhjulsgaffel. Som det fremgår av tegningene, er den mest påkjente del,av rammen, nemlig den.trekantformete hovedrammen, dannet av rørene 7, 8 og 9, som med sine ender 1, 2, 3,4 og 5, er skjøvet inn i forbindelsesmuffer og fastklebet. Rørene er dannet som sømløse, ekstruderte profiler, mens muf^-fene fortrinnsvis er utført som smidde eller støpte deler. Fig. 1 shows the main frame and the rear wheel frame, while fig. 2 shows a front wheel fork. As can be seen from the drawings, the most exposed part of the frame, namely the triangular main frame, is formed by the pipes 7, 8 and 9, which, with their ends 1, 2, 3, 4 and 5, are pushed into connecting sleeves and glued on. The pipes are formed as seamless, extruded profiles, while the muf^-fins are preferably made as forged or cast parts.
Det kan også anvendes en konstruksjon som er sammensveiset av.rør, henholdsvis av pressede platedeler. Fortrinnsvis anvendes utherdbare, elokserbare legeringer av typen ÅlMgSi eller AlMgZn. Eloksering gir ikke bare.en dekorativ over-flatebeskyttelse, men også en god festeflate i klebestedene, hvilket også kan oppnås ved hjelp av kjemisk forbehandling, slik som' beising. Vesentlig for styrken i klebeforbindelsene er. også en tilstrekkelig klebef late, hvilket vil si at forholdet mellom klebélerigdene på rørendene og diameteren av rørene It is also possible to use a construction which is welded together from pipes, respectively from pressed plate parts. Hardenable, anodizable alloys of the type AlMgSi or AlMgZn are preferably used. Anodizing not only provides a decorative surface protection, but also a good attachment surface in the adhesive places, which can also be achieved with the help of chemical pre-treatment, such as pickling. Essential for the strength of the adhesive connections is. also a sufficient adhesive surface, which means that the ratio between the adhesive tapes on the pipe ends and the diameter of the pipes
på stedene 1 og 2 er i det-minst 0.3, pg på stedene 3, 4 og 5in places 1 and 2 it is at least 0.3, pg in places 3, 4 and 5
i det minste 0.25, hvorved diameteren av rørene i hovedrammen er i dét minste 28 mm for røret"7 og i det minste 30 mm for rørene 8 og 9. I det tilfellet at muffene har kantpartier utformet som halspartier slik som endene av rørene, skal forholdet mellom middelverdien av alle de enkelte klebelengder og diameteren av røret på stedene 1 og 2, være i det minste 0.3, og på stedene 3, 4 og 5 i det minste 0.12. Gaffelhol-deren er fortrinnsvis, slik som vist, dannet av ett enkelt stykke, hvorved det spares to klebesteder og material. For-ta julsgaf felen fremstilles på liknende måte som rammene, hvorved gaffelbenene 11 utføres av lettmetallrør med sirkeltverr-snitt eller ovalt tverrsnitt, og som på stedet 14 klebes i muffen 13. Forholdet mellom klebelengden og det største tverrmål av gaffelbenet 11, skal på stedet 14 være i det minste 0.3, at least 0.25, whereby the diameter of the pipes in the main frame is at least 28 mm for pipe"7 and at least 30 mm for pipes 8 and 9. In the case that the sleeves have edge parts designed as neck parts such as the ends of the pipes, the ratio between the mean value of all the individual adhesive lengths and the diameter of the pipe at places 1 and 2, be at least 0.3, and at least 0.12 at places 3, 4 and 5. The fork holder is preferably, as shown, formed from one single piece, which saves two gluing places and material. For-take Christmas presents, the felt is produced in a similar way to the frames, whereby the fork legs 11 are made of light metal tubes with a circular cross-section or oval cross-section, and which are glued at place 14 into the sleeve 13. The relationship between the adhesive length and the largest transverse dimension of the fork leg 11, at location 14, must be at least 0.3,
hvorved det: største tverrmål av gaffelbenet 11 ved dvalt tverrsnitt er i det minste .30^ mm på stedet-.' 14, og ved sirkel tverr-snitt i det minste 25 mm. Med klebelengde menes den innskjøvne lengde som klebes. I tilfelle av en særlig kantutforming, skal forholdet mellom middelverdien av de enkelte klebelengder og det største tverrmål av gaffelbenet 11 på stedet 14 være i det minste 0.15. Som klebemiddel anvendes .fortrinnsvis et tokomponent-aralditt-metallklebemiddel, AW 13 6, bg herdemiddelet HY 994, fra CIBA-GÉIGY, som over lang tid og. inntil 80°G gir tilstrekkelig styrke. Størkningen av klebemiddelet inntreffer, etter av-kjøling av klebeforbindelsen, etter herdingen. whereby the: largest transverse dimension of the fork leg 11 in horizontal cross-section is at least .30^ mm at the site-.' 14, and for circular cross-section at least 25 mm. Adhesive length means the inserted length that is glued. In the case of a particular edge design, the ratio between the mean value of the individual adhesive lengths and the largest transverse dimension of the fork leg 11 at location 14 must be at least 0.15. As an adhesive, a two-component araldite metal adhesive, AW 13 6, with the hardener HY 994, from CIBA-GÉIGY, is preferably used, which over a long period of time and. up to 80°G provides sufficient strength. Solidification of the adhesive occurs, after cooling of the adhesive compound, after curing.
Oppfinnelsen er.ikke begrenset til dé viste utførelsesformer.The invention is not limited to the embodiments shown.
I stedet for ytre muffer., kan også. anvendes indre muffer som skyves inn i rørene og klebes. Også andre deler, slik som styresøylen 12<p>g styret, kan fremstilles av lettmetallrør med muffef<p>rbindelser, likeså holderne for forhjuls- og bak-hjulsakslene.... Instead of outer sleeves., can also. internal sleeves are used which are pushed into the pipes and glued. Also other parts, such as the steering column 12<p>g handlebars, can be made from light metal tubes with socket connections, as can the holders for the front and rear wheel axles....
