PATENT PATENT PERIOD FROM 14 FEBRUARY 1964 GRANTED ON 4 NOVEMBER 1965 PUBLISHED ON 3 MAY 1966 SWEDEN CLASS INTERNATIONAL SWEDISH B62 f63 d: 4 PATENT AND REGISTRATION DEPARTMENT Ans. 1839/1964 received on 14/2 1964 issued on 23/8 196 W RUF, BOTTIGHOFEN, SWITZERLAND Suspended pneumatic off-road wheel Priority requested Iran on 15 February, 20 February, 5 December, 19 December 1963 and 15 January 1964 (Federal Republic of Germany) Present invention refers to a bulletproof pneumatic off-road wheel, in which annular outer clamping means abut against a ham surface surface of a ring-shaped U-profile, consisting of elastic material.

Med ett skottsakert pneumatiskt terranghjul forstas hO,r ett sarskilt for militarfordon anvandbart hjul, vars kansliga delar delvis aro skyddade mot beskjutning, &eh som avail majliggor fortsatt korning, em dess ring perforeras av ett skott. By a bulletproof pneumatic off-road wheel is meant hO, is a special wheel usable for military vehicles, the probable parts of which are partly protected against shelling, & eh which avail may continue grinding, if its ring is perforated by a shot.

Vid kanda skottsakra fordonshjul är fortsatt karning efter puuktering genom beskjutning ofta lake langre mojlig, eftersom canedelbart efter beskjutningen luften fOrsvinner ur ringen och ringen slaknar, sa att ringen under inverkan av den densamma belastande fordonsvikten for del: mcsta omedelbart for-stores. For att eliminera denna olagenhet har det redan foreslagits att anbringa helgummihjul. Helgummihjul aro emellertid relativt oelastiska och tillata lake Miming med hOgie hastighet. In the case of bulletproof vehicle wheels, continued carriage after shearing by shelling is often even longer possible, since immediately after shelling the air disappears from the ring and the ring slackens, so that the ring under the influence of the same onerous vehicle weight for part: mcsta immediately for-stores. To eliminate this inconvenience, it has already been proposed to apply all-rubber wheels. However, all-wheel wheels are relatively inelastic and allow Lake Miming at high speed.

Uppfinningen liar till uppgift att avhjalpa dessa olagenheter och astadkomma ,ett skottsakert pneumatiskt terranghjul, vilket A ena sidan är skyddat mat sidobeskjutning av dess ring, ft andra sidan aven medgiver fortsatt kdrning med relativt hog hastighet, om ringen skulle perforeras av ett skott. The object of the invention is to remedy these imperfections and to provide a bulletproof pneumatic off-road wheel, which on the one hand is protected by side shelling of its ring, on the other hand also allows continued driving at a relatively high speed, if the ring were to be perforated by a shot.

Denna uppgift lases ,enligt uppfinningen darigenom att de ringformade yttre insphnningsmedlen uppvisa breda, med en terranggripprofil forsedda oversidor, vilka jamfort med den daremellan liggande ringens oversida uppvisa en sadan diameter, att hjulet vid fard ph gator och vagar endast vilar pa ringens oversida, vid fard i mjuk terrang emellertid pa Dupl. kl. 63 e: 21/03 den av inspanningsmedlens oversidor och ringens oversida bildade totalrullytan saint vi-dare .darigenorn, att den genom ringens ihalighet bildade pneumatiska kammarens overkant ligger lagre an de hada yttre inspanningsmedlens dverkant, sa att dess inspanningsmedeI skydda den pneumatiska karnmaren mot beskjutning fran sidan. This object is solved, according to the invention, by the annular outer recess means having wide upper sides provided with a terrain grip profile, which, compared with the upper side of the intermediate ring, have such a diameter that the wheel rests only on the upper side of the ring when driving in soft terrain, however, on Dupl. at 63 e: 21/03 the total roller surface formed by the upper rollers of the clamping means and the upper side of the ring furthermore, so that the upper edge of the pneumatic chamber formed by the ring hollow is lower than the upper edge of the outer clamping means, so that its clamping means protects the pneumatic vessel from shelling. from the side.

Darvid uppgar bredden av varje skankel hos ringen foretradesvis till 1/4-1/3 av ringens totalbredd. Tjockleken hos ringdacket motsvarar lampligen ungefar den inre hajden has namanda kammare. In this case, the width of each shank of the ring preferably amounts to 1 / 4-1 / 3 of the total width of the ring. The thickness of the ring deck is approximately equivalent to the inner chamber of the inner shark.

Vid en foredragen utforingsform av ett skottsakert pneumatiskt terranghjul enligt uppfinningen besta de yttre inspanuingsmedlen for ringen ,av tva falghalf ter, pA vilka sasom inre inspanningsmedel ar pasatt en ring, som a sin sida med sina sidoytor anligger mot ringskanklarnas innerytor. Namnda pasatta ring kan lampligen besta av minst tva delstycken. In a preferred embodiment of a bulletproof pneumatic off-road wheel according to the invention, the outer clamping means for the ring consist of two rim halves, on which, as inner clamping means, a ring is fitted, which in turn abuts the inner surfaces of the ring legs with their side surfaces. Said fitted ring can suitably consist of at least two parts.

Vid den foredragna utforingsformen av uppfinningen besta de inre och yttre inspanningsmedlen av en metall, vars varmeledningstal ligger over 045 cal/ern sek grad far att dftrmed bortfora den vid ringens valkarbete utvecklade varmen. In the preferred embodiment of the invention, the inner and outer clamping means consist of a metal, the thermal conductivity of which is above 045 cal / ern, so that the heat generated during the rolling work of the ring is removed.

Vidare aro -vid den foredragna utforingsformen av ett terranghjul enligt uppfinningen de yttre inspanningsmedlen Over elastiska me-del forbundna med den inre hjulkroppen, sa att en fjadrande forflyttning av de yttre inspanningsmedlen i forhallande till den hire hjulkroppen i axiell och radiell riktning mdj- ggar e s Vidare kunna enligt uppfinningen de inre och yttre inspanningsmedlen aven inbordes va- 2 ra formbundet lastagbart forbundna for att darmed oka hjulets stabilitet utan att paverka dess ovriga foretraden. Furthermore, in the preferred embodiment of a off-road wheel according to the invention, the outer clamping means above elastic means connected to the inner wheel body, so that a resilient movement of the outer clamping means in relation to the wheel body in the axial and radial direction is possible. Furthermore, according to the invention, the inner and outer clamping means can also be embedded in a formally loadable manner in order to thereby increase the stability of the wheel without affecting its other pre-wires.

Lampligen aro de yttre inspanningsmedlen och ringen forsedda med omsesidigt i varandra ingripande utsprang och ursparingar, vilka forhindra en relatimrorelse mellan, ringen och inspanningsmedlen. De yttre inspanningsmedlen are foretradesvis sh utformade, alt de med sina ytor tillsammans med .ringen bilda en del av hj ulets lopyta, varmid oversidorna av dessa inspanningsmedel kunna mara utformade med utatriktade valkar. The outer clamping means and the ring are suitably provided with mutually interlocking projections and recesses, which prevent a relative movement between the ring and the clamping means. The outer clamping means are preferably shaped so that they, with their surfaces together with the ring, form part of the running surface of the wheel, whereas the upper sides of these clamping means can be formed with outwardly directed valves.

Vid en ytterligare foredragen ulforingsform av ett skottsakert terringhjul enligt uppfinningen ar pa atmin,stone en, foretradesvis den utal liggande faighalften vid sidan en tillsatsfalgring paskruvad, vilken forokar lopytan for hjulet och minskar .det .specifika marktrycket, sa att ett med detta hjul utrustat 'fordon amen forblir korbart pa besvarlig och morasaktig mark. In a further preferred embodiment of a bulletproof tread wheel according to the invention, on the at least one stone, preferably the innumerable half of the shaft next to an additional rim is screwed on, which increases the running surface of the wheel and reduces the specific ground pressure, so that one equipped with this wheel vehicles amen remain drivable on responsive and morass-like ground.

Vid en ytterligare fOredragen utfOringsform av uppfinningen kunna valkarna pa falghalfterna och .ementuellt amen, valkarna pa tillsatsfalgringen ha ursparingar, i vilka nagot over valkarna utstaende inlagg av motstandskraftigt material, exempelvis stal, aro utbytbart inThrda. Des.sa inlagg kunna mid utnotning latt ersattas, med nya iulagg, sa att alltsa fdlghdlfterna sjalva praktiskt taget aro obegransat hallbara. In a further preferred embodiment of the invention, the whales on the rim halves and, optionally, the whales on the additional rim may have recesses in which any inserts of resistant material protruding above the whales, for example steel, are interchangeable. These inlays can be easily replaced with use, with new inserts, so that the follow-up lifts themselves are practically indefinitely durable.

Det i fig. 1-3 visade skottsakra terranghjulet .enligt uppfinningen har en inre hjulkropp 1, vilken pa manligt satt medelst skruvar 2 at fast mid ett hjulnav eller ett bromstrumhus 3. Pa omkretskanten am hjulet 1 aro med inbOrdes minkelamstand av foretradesvis 0-0 s. k. silent-block pasvetsade, vilka besta am en hylsa 4, i vilken en muff 5 ay elastiskt material, for etradesvis am gummi, och en inre hylsa 6 befinna sig.. Hylsorna 4 och 6 aro forbundna med den elastiska muffen 5, t. ex. genom mutkanisering. The bulletproof off-road wheel shown in Figs. 1-3 according to the invention has an inner wheel body 1, which is mounted on a male means by means of screws 2 attached to a wheel hub or a brake drum housing 3. On the circumferential edge of the wheel 1 there is a minimum diameter of preferably 0-0. so-called silent-block welds, which consist of a sleeve 4, in which a sleeve 5 of elastic material, for example rubber, and an inner sleeve 6 are located. The sleeves 4 and 6 are connected to the elastic sleeve 5, t. ex. by bribery.

Vid den visade utforingsformen har hjulet tva generellt symmetriska falghalfter 7 och 8, pa vilka en ring 9 är pasatt, vilken med sina U-formigt utstaende kanter 10 och 11 stoder mot faighalfterna 7 och 8. Derma ring kan eventuellt amen besta av tvd eller flera segment. De back falghalfterna 7 och 8 aro forbundna med varandra och Over hylsan 6, muffen 5 och hylsan 4 med den inre hjulkroppen 1 genom skrumbultar 20. Pa grund av muffens 5 elastiska material erhaller datigenom hjulet en miss tillsatsegenfjadring .och kan under fard arbeta sa.val radiellt som axiellt. In the embodiment shown, the wheel has two generally symmetrical rim halves 7 and 8, on which a ring 9 is fitted, which with its U-shaped projecting edges 10 and 11 stands against the groove halves 7 and 8. These rings may optionally consist of two or more segment. The rear rim halves 7 and 8 are connected to each other and the upper sleeve 6, the sleeve 5 and the sleeve 4 to the inner wheel body 1 through screw bolts 20. Due to the elastic material of the sleeve 5, the wheel thereby receives a lack of additional suspension and can operate in this way. choice radially as well as axially.

Pa de sasom yttre inspanningsmedel verkande falghalfterna 7 och 8 air en i tvarsekHon IT-forraig ring 12 av elastiskt material pasatt, vilken har vulstartad fortjockade shanklar 13 och 14. Faighalfterna 7 och 8 aro med sina ovre, den storsta diameter. besittande kanter 16 och 17 indragna mot hjulmittplanet, sa att de mulstformiga fiirtj ockningarna omgripa skanklarna 13 och 14 am gummiringen 12. Bredden hos skanklarna 13 och 14 pa ringen 12 uppgar lampligen till 1/4-1/3 eller firer av ringen s 12 totalbrecld. The rim halves 7 and 8 acting on the outer clamping means 7 and 8 are fitted with a transverse IT supply ring 12 of elastic material, which has vulcanized thickened shanks 13 and 14. The shaft halves 7 and 8 are, with their upper ones, the largest diameter. possessing edges 16 and 17 retracted towards the wheel center plane, so that the cloud-shaped projections surround the shanks 13 and 14 in the rubber ring 12. The width of the shanks 13 and 14 on the ring 12 is suitably 1 / 4-1 / 3 or four of the ring s 12 total brecld .

Pa yttersidan av skanklarna 13 och 14 are vartformiga utsprang 25 am cirkelrund tmarsektion. anordnade, vilka ingripa i komptementart utformade ursparingar 26 pa innersidorn.a am falghalfterna 7 och 8 oak farhindra en inbOrdes vridning am ringen och falghalfterna. Naturligtvis kunna de inbordes i varandra ingripande utsprangen och ursparingarna vara utformade pa annat satt an som visas pa ritningen,. Speciellt kunna utsprangen amen sta ut fran falghalterna och ingripa i fordjupningar pa ringen. On the outside of the shanks 13 and 14 there are shaped projections 25 in a circular timber section. arranged, which engage in compartment-shaped recesses 26 on the inner sides of the rim halves 7 and 8 and do not prevent an inward rotation of the ring and the rim halves. Of course, the interlocking projections and recesses may be formed in a manner other than that shown in the drawing. In particular, the protrusions may protrude from the rim holders and intervene in depressions on the ring.

Den sasom inre inspanningsmedel for ring-en 12 verkande ringen 9 Or foretradesmis nagot bredare an inneravstandet mellan ringskanklarna 13 och 14, sa att den later sig fast inspannas mellan de sistnananda. Dc visentligen lodratt forlopande sidoytorna av ringen 9 uppvisa vardera minst en vulst eller ett ringspar 31 resp. 32, i vilka mid inpressning av ringen 9 mellan ringskanklarfla 13 och 14 det elastiska ringmaterialet intranger, sã att p0. detta satt en 1abyrinttatning uppstar, vilken fullstandigt 3 tatar kammaren 15 mellan ringen 9 och ring-en 12. Denina kammare 15 kan, om .sa Onskas, over en yentil 27 dessutom uppumpa,s med lull, yilket emellertid icke obetingat ar erforderligt eller kan i densamma en pa vanligt sa.tt upppumpbar luftslang 28 inlfiggas. Ringen 12 ar darvid sh dimensionerad, att tjcpckleken hos ringdacket vasentligen fir lika med hoiden av kammaren 15. The inner clamping means for the ring 12 acting on the ring 9 is slightly wider than the inner distance between the ring shanks 13 and 14, so that it can be firmly clamped between the latter. The visually vertically extending side surfaces of the ring 9 each have at least one bead or a pair of rings 31 resp. 32, in which, by pressing the ring 9 between the ring shank surface 13 and 14, the elastic ring material penetrates, so that p0. this set a 1abyrinttatting arises, which completely 3 takes the chamber 15 between the ring 9 and the ring-12. The chamber 15 can, if desired, over a yentil 27 also inflate, s with wool, which, however, is not unconditionally required or can in the same one in the usual way inflatable air hose 28 is inserted. The ring 12 is then dimensioned so that the thickness of the ring roof is substantially equal to the height of the chamber 15.

Montaget av terrangbjulet enligt uppfinningen sker ph foliande satt. The assembly of the terrain wheel according to the invention takes place in a foiling manner.

Ringen 9, vilken for underlattande av montaget kan best& ay tya halfter, intryckes mellan skanklarna 13 och 14 hos ringen 12. Harpa pdskj utes ringen pa ena hfilften, t. ex. falghalften 8. Darefter phsattes falghalften 7. Bhda falghalfterna forbindas slutligen over skrui-hultarna 20 med varandra och med hjulkroppen 1. Vid atdragning ay skruvforbindelserna inspannaS skanklarna 13 och 14 mellan sidoytorna ph ringen 9 och falghalfterna: 7 och 8 sa fast, att ingen luft kan uttranga ur kammaren 15. The ring 9, which for ease of assembly can consist of ten halves, is pressed between the shanks 13 and 14 of the ring 12. Harp pads are applied to the ring on one half, e.g. the rivet half 8. Then the rivet half 7 is fixed. Both rims are finally connected over the screw holes 20 to each other and to the wheel body 1. When tightening the screw connections, the shanks 13 and 14 are clamped between the side surfaces of the ring 9 and the rivet halves: 7 and 8 so that no air can protrude from the chamber 15.

Den mellan ringen 9 och ringen 12 utformade kammaren 15 ligger sa, att dess ovre nv innersidan ph ringdacket hildade b.egransningsyta ligger under de Ovre sidokanterna 16 ()eh 17 av falghalfterna 7 och 8. Kammaren 15 är darme.d salirad mot frhn sidan och snett mot fardriktningen for fordonet riktad beskjutning. Skulle ,emellertid likval ett I. ex. framifran traffande skott intranga i kaminaren 15, sh att den icke langre skulle fullstandigt tata utat och likaledes den i densamma innehallna luften skulle forsyinna, sh kan det med det beskrivna hjulet utrustade fordonet likafullt kora vidare och narmare bestamt pa grund darav att A ena sidan ringen 12 ph grand av sina bre.da skanklar 13 o.ch 14 och sitt tjocka .dack basitter en viss egenstyvhet och den i .aila fall -endast kan intryckas den retativt ringa hoj den hos kammaren 15, men darvid emellertid yilar ph ringen 9, och emedan a andra sidan ringen 12 med sina utsprang 25 star i stabilt ingre.pp med falghalfterna 7 och 8, sa att alltsa en relativ vridning mellan ringen och falghalfterna ar utesluten. The chamber 15 formed between the ring 9 and the ring 12 is located so that its upper nv inner side of the ring roof inclined boundary surface lies below the upper side edges 16 () eh 17 of the rim halves 7 and 8. The chamber 15 is thus salaried towards the front side and obliquely to the direction of travel of the vehicle directed shelling. Would, however, nevertheless an I. ex. shot from the front penetrating into the chamber 15, sh that it would no longer completely take out and likewise the air contained in it would supply, sh the vehicle equipped with the described wheel can still drive further and more precisely determined due to the fact that on one side the ring 12 ph grand of its broad shanks 13 and 14 and its thick .dack basits a certain intrinsic stiffness and it in .aila -only can be pressed the relatively small hoy it of the chamber 15, but thereby yilar ph ring 9, and since on the other hand the ring 12 with its projections 25 is in stable engagement with the rim halves 7 and 8, so that a relative rotation between the ring and the rim halves is excluded.

De pa sidorna hos Angela 12 anliggande falghalfterna 7 och 8 liksom ringen 9 aro lampligen utformade ay en metall, t. ex. en aluminiumlegering, med ett varmeledningstal stone an 0,15, foretradesyis storre an 0,3 cal/ cm-1 s.ek-1 grad-1. Pa detta satt kan den yid valkarbetet for ringen 12 under farden utveeklade varmen vOl avledas, vilket innebar en ytterligare fordel med det skottsakra terranghjulet enligt uppfinningen. Darvid kunna de med yarandra i beroring stae,n.de ytorna hos inspanningsmadlen 7, 8, 9 och ringen 12 .dess uto.m ha en, den. varmeavledande ytan forstorand.e profilering. The rim halves 7 and 8 abutting on the sides of Angela 12 as well as the ring 9 are suitably formed of a metal, e.g. an aluminum alloy, with a thermal conductivity of 0.15, is preferably greater than 0.3 cal / cm-1 sec-1 degree-1. In this way, the heat vOl can be dissipated during the rolling work of the ring 12 during the journey, which entailed a further advantage with the bulletproof off-road wheel according to the invention. In this case, they can be in contact with each other, n.de the surfaces of the clamping means 7, 8, 9 and the ring 12 .dess uto.m have one, the. heat dissipating surface enlarging.e profiling.

Generelit ,ar ringen 9 pasatt lost pi falghalfterna 7 och 8. For okand.e ay stabiliteten hos terranghjulet kan det dock i manga fall yarn lampligt att mellan de hare och yttre inspannings.medlen, dvs. falghalfterna 7, 8 och ring-en 9 anordna an formbunden forbin.delse. F8r delta andamal kunna, se fig. 2 och 4, med yinkelaystand ph innersidan air ringen. 9 inat utsthende, relativt breda vaggar 35 yidsvetsas. Dessa va.ggar 35 ligga idarvid lamplige.n pa sa.- dant vinkelaystand, att de komma att ligga mellan tvh av namnda silent-block, Over vilka falghalfterna 7 och 8 aro forbundua med hjulinnerkroppen 1. Vaggarna 35 uppvisa borrningar 36, vilka ligga inriktade med borrningarna 37 och 37' pa de hire omkretskanterna 38, 39 av falghalfterna 7 och 8. Harpa inskruvas under mellanlagg cv lampliga underlagsskiyor en butt 40, pa vars dude en mutter 41 paskruvas. PA delta salt later sig yaggen 35 fast ehuru lostagbart sammanspannas med falghalfterna 7 och 8, .sd att darvid aven ring-en 9 Sr formbundet forbu.nden med falghdlfterna och terranghjulet sasom helhet darigenom erhaller forbattrad hallfasthet, utan att .darmed den elastiska forbindelsen mellan falghalfterna 7 och 8 med hjulkroppen 1 payerkas. In general, the ring 9 is fitted loosely on the rim halves 7 and 8. For the stability of the off-road wheel, however, in many cases it may be appropriate to use the means between the hair and the external clamping means, ie. the rim halves 7, 8 and the ring 9 arrange a form-fitting connection. To participate andamal be able to, see Figs. 2 and 4, with yinkelaystand ph inside air ring. 9 inat protruding, relatively wide cradles 35 yidsvetsas. These walls 35 lie in such a lamplike position that they come to lie between two of the said silent blocks, over which the rim halves 7 and 8 are connected to the wheel inner body 1. The cradles 35 have bores 36, which lie aligned with the bores 37 and 37 'on the hire circumferential edges 38, 39 of the rim halves 7 and 8. Harp is screwed under intermediate layers or suitable underlay skis a butt 40, on whose dude a nut 41 is screwed. PA delta salt allows the yag 35 to be fixed, although releasably coupled to the rim halves 7 and 8, so that the ring 9 is also formally connected to the rim halves and the off-road wheel as a whole thereby obtaining improved half-strength, without thereby the elastic connection between rim halves 7 and 8 with wheel body 1 payerkas.

Sasom sarskilt framgar ay fig. 1 och 3, utskjuta frill de at sidan utkragade falghalfterna 7 och 8 vulster 18 och 19. Oversidorna av .dessa vulster bilda tillsammans med ringdacket en del ay hjulets lopyta, yarvid ring-ens 12 dick bildar cirka halften ay totalbredden av lopytan. Sasom framgar ay fig. 1 och 3, dr dock oversidan av det likatedes med mister forsedda ringdacket avstegad mot oversidan ay vulsterna 18 och 19 pa .det sattet att Oversidan ay ringdacket ligger hii.gre din oversidan av vulsterna 18, 19. As can be seen in Figs. 1 and 3 in particular, the ridge halves 7 and 8 cantilevered on the side protrude beads 18 and 19. The upper sides of these beads together with the ring deck form part of the running surface of the wheel, while the 12 dicks of the ring form about half ay. the total width of the running surface. As can be seen in Figs. 1 and 3, however, the upper side of the similar ring-bearing ring deck is lowered towards the upper side of the beads 18 and 19 in such a way that the upper side of the ring deck lies to the upper side of the beads 18, 19.

Om darfor fordonet ror sig pa ett normalt stadigt underlag, I. ex. ,en gala, kommer den verkliga lopytan av hjulet blott att bildas av ringdacket, eftersom vulsterna 18 i detta fall icke komma i b.erOring. med underlaget. Darmed kommer fordonet under dessa o.mstandighater att tiaras mer elastiskt. Vulsterna 18 an_ gripa marken forst, .da fordonet kor Over mjuknaark, van i ringen 12 sjunker med. If therefore the vehicle moves on a normally stable surface, I. ex. , a gala, the actual running surface of the wheel will only be formed by the ring tire, since the beads 18 in this case will not come into contact. with the substrate. As a result, the vehicle will be more resilient under these conditions. The bumps 18 attack the ground first, when the vehicle crosses over the soft sheet, the van in the ring 12 sinks with it.

For att yid lard ph mink .eller morasaktig mark minska det sp.ecifika marktry.cket for terranghjulet kan enligt u.ppfinningen, se fig. 6-8, ph atminstone en falghalft 7, 8 en tillsatsfalgring 45 vara paskruvad, vilken akar hjulets lopyta. Tillsatsfalgringen 45, som likalades kan Oxen uppvisa utstaende vulster 46, paslumvas :claryid fOretradesyis pa den pa yttersidan av hjulet belagna falghalften 7. According to the invention, in order to reduce the specific ground pressure for the off-road wheel, see Figs. 6-8, ph at least one rim half 7, 8 an additional rim ring 45 can be screwed on, which cuts the running surface of the wheel. . The accessory ridge 45, which likewise can have the bulge protruding beads 46, paslumvas: claryid fOretradesyis on the ridge half coated on the outside of the wheel 7.

Faighalfterna 7 och 8 uppvisa en nedat 4 utdragen kant 'eller vagg 47, pa vars yttersida en avsats. 48 forefinnes.

Eftersom armed de vid fard upptradande pakanningarna vasentligen upptagas av stalinlaggen 66, Tacker det att da och da utbyta desanama, vilket utan vidare kan she genom losgorande av skruybutten 68. Erfarenheten liar visat, att det kan vara lampligt att forse stalinlagget 66 med skarpt slipade kanter, vilket sarskilt pa gra.smark ger terranghjulet fortraffliga koregenskaper. Harvid kan det racka att da och d efterslipa stalinlaggens 66 kanter. Since the gaskets appearing on the road are essentially taken up by the Stalin layer 66, it is thanks to the occasional exchange of the desanama, which can easily be done by loosening the screw cap 68. Experience has shown that it can be convenient to provide the stalin layer 66 with sharply sharpened edges. , which especially on gra.smark gives the terrain wheel excellent driving characteristics. Then it may be time to grind the 66 edges of the stalin layer from time to time.
