Description

Denne oppfinnelse vedrører et tvillinghjul ifølge innledningen til patentkrav 1. This invention relates to a twin wheel according to the introduction to patent claim 1.

Forskjellige utførelser av tvillinghjul er tidligere kjent. Det kan f.eks. henvises til US patenter 3 323 088, 3 836 202, 4 030 753 og 3 337 270. Det sistnevnte patentskrift omfatter et tvillinghjul med en kjøretøyhjulfelg og en ytterfelg, en mellom felgene anordnet koblingsinnretning, en avstandsring festet til ytterfelgen, en festering som er festet til innerflaten av en innbuktet forsterkningsrille, samt flere strammeinnretninger som er løsbart festet til festeringen. Various designs of twin wheels are previously known. It can e.g. refer to US patents 3 323 088, 3 836 202, 4 030 753 and 3 337 270. The latter patent document comprises a twin wheel with a vehicle wheel rim and an outer rim, a coupling device arranged between the rims, a spacer ring attached to the outer rim, a fastening ring which is attached to the inner surface of an indented reinforcement groove, as well as several tensioning devices which are releasably attached to the fastening ring.

Svakheten ved de kjente utførelser er at monteringen av det ytre hjul bare kan foretas i bestemte hjulstillinger og/eller at det er nødvendig å stramme til hver eneste boltmutter for fastspenning av ytterhjulet slik at monteringen blir ganske tidkrevende. The weakness of the known designs is that the assembly of the outer wheel can only be carried out in specific wheel positions and/or that it is necessary to tighten each and every bolt nut to secure the outer wheel so that assembly becomes quite time-consuming.

Hensikten med oppfinnelsen er å tilveiebringe et tvillinghjul av den innledningsvis nevnte art som er uten de omtalte svakheter og som allikevel kan fremstilles med rimelige omkostninger. The purpose of the invention is to provide a twin wheel of the kind mentioned at the outset which is without the mentioned weaknesses and which can nevertheless be produced at reasonable costs.

Denne oppgave har man løst som angitt i karakteristikken til patentkrav 1. Ytterligere fordelaktige utførelser fremgår av de avhengige patentkrav. This task has been solved as indicated in the characteristics of patent claim 1. Further advantageous embodiments appear from the dependent patent claims.

Fordelen ved tvillinghjulet ifølge oppfinnelsen er at ytterhjulet kan kobles til kjøretøyhjulet i enhver forønsket stilling, slik at også store, tunge hjul kan monteres uten vanskeligheter. The advantage of the twin wheel according to the invention is that the outer wheel can be connected to the vehicle wheel in any desired position, so that even large, heavy wheels can be mounted without difficulty.

En ytterligere fordel består i at stranimeinnr etningene kan gjøres meget korte, hvilket fører til at avstandsringen med ytterhjulet dreies bare meget lite mot kjøretøyhjulet, da de omtalte strammeinnretninger ved denne operasjon tilbakelegger en bevegelse med tilsvarende mindre radius og derfor avviker raskere fra befestigelsesringen som danner tangenten. Dette forhold bidrar også til høyere stabilitet. A further advantage consists in the fact that the side devices can be made very short, which means that the spacer ring with the outer wheel is turned only very slightly towards the vehicle wheel, as the said tensioning devices during this operation cover a movement with a correspondingly smaller radius and therefore deviate more quickly from the fastening ring which forms the tangent . This ratio also contributes to higher stability.

Oppfinnelsen skal forklares nærmere nedenfor ved hjelp av et eksempel med henvisning til tegningen som viser et radialsnitt gjennom et tvillinghjul med kobling. The invention will be explained in more detail below by means of an example with reference to the drawing showing a radial section through a twin wheel with coupling.

Tvillinghjulet omfatter en ytre felg 1, hvori en skulder 12 bærer en påsveiset avstandsring 2 som fastholdes med sveisepunkter 9. Flere, langs omkretsen fordelte, løsbare, koaksialt virkende strammeinnretninger 3 spenner den ytre felg 1 fast i kjøretøyfelgen 4. Strammeinnretningene 3 er på kjøretøysiden hengt opp i ringmuttere 5, hhv. påsveisebøyler som er forbundet med hjulskiven. På ytterfelgsiden er strammeinnretningene 3 opphengt i en festering 6. Festeringen 6 er sveiset til en forsterkningsrille 7 av avstandsringen 2 med en sveisesøm 8, slik at en side av festeringen 6 rager frem og danner et gap mot avstandsringen 2, slik at strammeinnretningene 3 med sine spennhaker 15 kan henges opp i festeringen 6. Da festeringen 6 er sveiset inn med en endeløs søm, kan strammeinnretningene 3 henges opp på et hvilket som helst sted. Derfor kan ytterhjulet i en hvilken som helst stilling kobles inn til kjørehjulet, fordi strammeinnretningene 3 kan henges opp i festeringen 6 på det sted som befinner seg på samme høyde som ringmutterne 5. Også meget tunge tvillinghjul kan uten vanskeligheter tilkobles, da det ikke lenger kreves noen medbringerknast. Da det ikke finnes noen knaster til overføring av de radiale krefter på kjøretøysiden, dreies distanseringen 2 ved kjøring under belastning mot kjøretøyhjulet. Derved trekker strammeinnretningene 3 ytterhjulet over distanseringen 2 enda sterkere inn til kjøretøyhjulet. Som følge av denne konstruksjon for opphengning av strammeinnretningene i tvillinghjulet, oppnås, en meget stor stivhet for hjulet. Den særlige stivhet tillater at drivknastene kan sløyfes og derfor kan også tunge tvillinghjul kobles til uten anstrengelse og uten at de først må dreies til en bestemt koblingsstilling. The twin wheel comprises an outer rim 1, in which a shoulder 12 carries a welded-on spacer ring 2 which is held in place by welding points 9. Several, distributed along the circumference, detachable, coaxially acting tensioning devices 3 clamp the outer rim 1 firmly in the vehicle rim 4. The tensioning devices 3 are suspended on the vehicle side up into ring nuts 5, respectively. welding brackets that are connected to the wheel disc. On the outer rim side, the tensioning devices 3 are suspended in a fastening ring 6. The fastening ring 6 is welded to a reinforcement groove 7 of the spacer ring 2 with a welding seam 8, so that one side of the fastening ring 6 protrudes and forms a gap against the spacer ring 2, so that the tensioning devices 3 with their buckle 15 can be suspended in the fastening ring 6. As the fastening ring 6 is welded in with an endless seam, the tensioning devices 3 can be suspended in any place. Therefore, the outer wheel can be connected to the driving wheel in any position, because the tensioning devices 3 can be suspended in the fastening ring 6 at the place which is at the same height as the ring nuts 5. Even very heavy twin wheels can be connected without difficulty, as it is no longer required some carrier cams. As there are no cams for transmitting the radial forces on the vehicle side, the spacer 2 is turned when driving under load towards the vehicle wheel. Thereby, the tensioning devices 3 pull the outer wheel over the spacer 2 even more strongly towards the vehicle wheel. As a result of this construction for suspending the tensioning devices in the twin wheel, a very large stiffness is achieved for the wheel. The special stiffness allows the drive cams to be looped and therefore even heavy twin wheels can be connected without effort and without first having to be turned to a specific coupling position.

Forsterkningsrillen 7, som f.eks. fremstilles ved innvalsing, tjener som ansatssted for festeringen 6 og som forsterkningselement for avstandsringen 2. Ved sterkt belastede tvillinghjul, kan også flere forsterkningsriller 7 anbringes på avstandsringen 2 og rillene kan være ombukket utover eller innover. The reinforcement groove 7, which e.g. produced by rolling, serves as a contact point for the fastening ring 6 and as a reinforcement element for the spacer ring 2. In the case of heavily loaded twin wheels, several reinforcement grooves 7 can also be placed on the spacer ring 2 and the grooves can be bent outwards or inwards.

Antallet av strammeinnretningene 3 kan tilpasses etter den forventede belastning på tvillinghjulet. The number of tensioning devices 3 can be adjusted according to the expected load on the twin wheel.

Forsterkningsrillen 7 kan også erstattes med en flensring av jern som er festet til avstandsringen 2, og til hvilken flensring festeringen 6 sveises slik at det blir igjen et gap for å tillate epphengninge"n av spennhaken 15. Forsterkningsrillen 7 med festeringen 6 kan imidlertid også være anbragt på den ytre felg Avstandsringen 2 er sammensveiset eller sammenskrudd med den ytre felg 1. Ved igangsetting av kjøretøyet dreies ytterhjulet lett mot innerhjulet, hvilket bevirker en ytterligere tilnærming for avstivning av de to enkelthjul. The reinforcement groove 7 can also be replaced with a flange ring of iron which is attached to the spacer ring 2, and to which flange ring the fastening ring 6 is welded so that a gap is left to allow the suspension of the tension hook 15. The reinforcement groove 7 with the fastening ring 6 can, however, also be placed on the outer rim The spacer ring 2 is welded together or screwed together with the outer rim 1. When starting the vehicle, the outer wheel is turned slightly towards the inner wheel, which causes a further approach for bracing the two individual wheels.

Strammeinnretningene 3 strammes ved hjelp av et firkantrør 14, og sperrestrekningen 10 innstilles ved hjelp av et innstillbart underlag 11 (kneleddvirkning). The tensioning devices 3 are tightened by means of a square tube 14, and the locking stretch 10 is adjusted by means of an adjustable base 11 (knee joint action).
