Description
Foreliggende oppfinnelse angår en to-hjuls sykkel medThe present invention relates to a two-wheeled bicycle with
ramme og/eller gaffel av lettmetallprofiler, som er forbundet med hverandre ved hjelp av muffer. Kjente, vanlige sykler med en forhjulsgaffel, en hovedramme og en bakhjuls-ramme, er fremstilt av sømløse stålrør og forbindelsesmuffer, i hvilke stålrørene er slagloddet. Til tross for små dimen-sjoner 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. Ettersom slaglodding av lettmetall er utelukket av fasthets- og korrosjonstekniske grunner, blir rørene skrudd inn i muffene med fingjenger. For i en viss grad å kompensere for kjervvirkningen av gjengene, må disse rør i området ved sammenføyningsstedene forsterkes med innskjøvne rørhylser, hvilket betyr en øking av fremstillingsomkostnirrge: ene og en vektøking. Dessuten har disse syklene ikke den nødvendige stivhet, slik som stålkonstruksjonen, slik at for-bindelsene kan løsne under belastning. frame and/or fork made of light metal profiles, which are connected to each other by means of sleeves. Known common bicycles with a front wheel fork, a main frame and a rear wheel frame are made of seamless steel tubes and 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 exposed to rust. In addition, a construction is known in which sockets and pipes made of light metal and with approximately the same external dimensions are used. As impact soldering of light metal is excluded for strength and corrosion technical reasons, the pipes are screwed into the sleeves with fine threads. In order to compensate to a certain extent for the notching effect of the threads, these pipes in the area of the joining points must be reinforced with pushed-in pipe sleeves, which means an increase in manufacturing costs: one and an increase in weight. Moreover, these bikes do not have the necessary rigidity, such as the steel construction, so that the connections can loosen under load.
Foreliggende oppfinnelse tar som sitt utgangspunkt'.sen lett-metallsykkelramme hvis hulprofiler er innbyrdes forbundet ved hjelp av muffer, idet forbindelsen mellom muffer og profiler er dannet utelukkende ved hjelp av et klebemiddel. The present invention takes as its starting point the light metal bicycle frame whose hollow profiles are interconnected by means of sleeves, the connection between sleeves and profiles being formed exclusively by means of an adhesive.
Det særegne ved oppfinnelsen består i at gaffelbenene på overgangsstedet mellom gaffelben og gaffelhodemuffe, som i og for seg kjent, er utformet med ovalt eller sirkelrundt rørtverrsnitt og at forholdet mellom klebelengden og det største tverrmål på gaffelbenet ved det nevnte overgangssted utgjør 0,3 - 1,5, idet det største tverrmål for gaffelbenet utgjør minst 30 mm i oval utførelse og minst 25 mm i sirkelrund utførelse. The peculiarity of the invention consists in that the fork legs at the transition point between the fork leg and fork head sleeve, which is known in and of itself, are designed with an oval or circular tube cross-section and that the ratio between the length of the clamp and the largest transverse dimension of the fork leg at the aforementioned transition point amounts to 0.3 - 1 .5, as the largest transverse dimension of the fork leg is at least 30 mm in the oval design and at least 25 mm in the circular design.
Videre er det i henhold til oppfinnelsen foreslått at halsen på gaffelhodemuffen, som i og for seg kjent, har en særlig utformet kant og at endene av gaffelbenene, som i og for seg kjent, har en særlig utformet kant, idet forholdet mellom middelverdien av summen av samtlige klebelengder og det største tverrmål for gaffelbenet ved det nevnte overgangssted utgjør 0,15 - 1,5. Furthermore, according to the invention, it is proposed that the neck of the fork head sleeve, which is known per se, has a particularly designed edge and that the ends of the fork legs, which are known per se, have a particularly designed edge, the ratio between the mean value of the sum of all adhesive lengths and the largest transverse dimension of the fork leg at the aforementioned transition point amounts to 0.15 - 1.5.
Med en sykkelramme som foreslått ved foreliggende oppfinnelse oppnås lavere vekt og allikevel omtrent samme stivhet som for sykler med stålramme, og også meget gode styreforhold. With a bicycle frame as proposed by the present invention, a lower weight is achieved and still approximately the same stiffness as for bicycles with a steel frame, and also very good steering conditions.
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 av sømløse, ekstruderte profiler, mens muffene fortrinnsvis er utført som smidde eller støpte deler. Det kan også anvendes en konstruksjon som er sammensveiset 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 tubes 7, 8 and 9, which with their ends 1,2, 3,4 and 5 are pushed into connection sleeves and glued. The pipes are formed from seamless, extruded profiles, while the sleeves are preferably made as forged or cast parts. A construction which is welded together can also be used
av rør, henholdsvis av pressede platedeler. Fortrinnsvis anvendes utherdbare, elokserbare legeringer av typen AlMgSi 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 ik&ébeforbindelsene er også en tilstrekkelig klebeflate, hvilket vil si at forholdet mellom klebelengdene på rørendene og diameteren av rørene på stedene 1 og 2 er i det minste 0,3, og på stedene 3,4 og 5 i det minste 0.25, hvorved diameteren av rørene i hovedrammen er i det minste 2 8 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. Gaffel-holderen er fortrinnsvis,slik som vist, dannet av ett enkelt stykke, hvorved det spares to klebesteder og material. For-hjulsgaffelen fremstilles på liknende måte som rammene, hvorved gaffelbenene 11 utføres av lettmetallrør som sirkeltverr- of pipes, respectively of 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 connections is also a sufficient adhesive surface, which means that the ratio between the adhesive lengths of the pipe ends and the diameter of the pipes at places 1 and 2 is at least 0.3, and at places 3,4 and 5 at least 0.25, whereby the diameter of the pipes in the main frame is at least 2 8 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 places 3,4 and 5 at least 0.12. The fork holder is preferably, as shown, formed from a single piece, whereby two adhesive points and material are saved. The front wheel fork is produced in a similar way to the frames, whereby the fork legs 11 are made of light metal tubes as circular cross-
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, hvorved det største tverrmål av gaffelbenet 11 section or oval cross-section, and which is glued into the sleeve 13 at location 14. The ratio between the adhesive length and the largest cross-sectional dimension of the fork leg 11 must be at least 0.3 at location 14, whereby the largest cross-sectional dimension of the fork leg 11
ved ovalt tverrsnitt er i det minste 30 mm på stedet 14, og ved sirkeltverrsnitt i det minste 25 mm. Med klebelengde menes den innskjøvne lengde §om 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 fottrinnsvis et tokomponent-aralditt-metallklebemiddel, AW 136, og herdemiddelet HY 994, fra CIBA-GEIGY, som over in the case of an oval cross-section, at least 30 mm is at place 14, and in the case of a circular cross-section, at least 25 mm. Adhesive length refers to the inserted length to be 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 136, and the hardener HY 994, from CIBA-GEIGY, are used step by step, as above
lang tid og inntil 80°C gir tilstrekkelig styrke. Størk-ningen av klebemiddelet inntreffer etter avkjøling av klebe-forbindelsen, etter herdingen. long time and up to 80°C gives sufficient strength. The solidification of the adhesive occurs after cooling of the adhesive compound, after curing.
Oppfinnelsen er ikke begrenset til de viste utførelsesformer.The invention is not limited to the embodiments shown.
I stedet for ytre muffer, kan også anvendes indre mufferInstead of outer sleeves, inner sleeves can also be used
som skyves inn i rørene og klebes. Også andre deler, slik som styresøylen 12 og styret, kan fremstilles av lettmetall-rør med muffeforbindelser, likeså holderne for forhjuls- og bakhjulsakslene. which is pushed into the pipes and glued. Other parts, such as the steering column 12 and the handlebars, can also be made from light metal tubes with socket connections, as can the holders for the front and rear wheel axles.
