av den nødvendige slaglengde for stemp-lene måtte sylindrene gjøres forholdsvis of the required stroke length for the pistons, the cylinders had to be made proportionately

lange, og for til tross for dette å kunne long, and despite this to be able to

holde lagrenes stilling i rammen så lav som keep the position of the bearings in the frame as low as

En ulempe ved den nettopp nevnte A disadvantage of the one just mentioned

enkle lagring av sylindrene er at delene ved easy storage of the cylinders is that the parts at

påkjøring av en jordfast gjenstand med hitting an earth-fixed object with

skuffebladets ytre sidepartier utsettes for the outer side parts of the drawer leaf are exposed to

meget sterke bruddpåkjenninger og derfor very strong breaking stresses and therefore

må dimensjoneres meget sterkt for å tåle must be designed very strongly to withstand

slike påkjenninger. For å unngå slike påkjenninger er det kjent å lagre hver sylinder dreibart om en akse som både er vinkelrett på tappaksen og sylinderaksen. I such stresses. To avoid such stresses, it is known to store each cylinder rotatably about an axis which is both perpendicular to the pin axis and the cylinder axis. IN

dette tilfelle har man utformet den ytre in this case the outer one has been designed

ende av lagertappen som er lagret i ram- end of the bearing pin which is stored in the frame

men som en gaffel som griper om sylinderen. Gaffelens armer er innrettet til å oppta vridbart hver sin av to tapper som på den nevnte vinkelrette akse er festet på sylinderens motsatte sider. Man kan even-tuelt istedenfor åirse tapper feste på sylinderen to lagre med lagerboringer for vridbar lagring av tapper som er anordnet i gaffelarmene. but like a fork gripping the cylinder. The arms of the fork are arranged to rotatably receive each of two pins which are fixed on the aforementioned perpendicular axis on opposite sides of the cylinder. Alternatively, instead of iron pins, two bearings with bearing bores can be attached to the cylinder for rotatable storage of pins arranged in the fork arms.

De to ovenfor beskrevne sylinderopp-hengninger forutsetter at enten en eller to tapper henholdsvis to lagre festes på selve sylinderen, hvilket bare kan gjøres ved sveising hvis man vil unngå kostbar spe-sialutformning av sylinderen. Oppvarm-ning av sylinderen under sveisingen fører imidlertid med seg en deformering av sylinderen, slik at sylinderløpet deretter må underkastes etterbearbeidelse for utret-ning. Denne operasjon innebærer betyde-lige ekstra omkostninger, og hovedhensik-ten med oppfinnelsen er å unngå slike omkostninger ved en sylinderopphengnings-anordning av den her omtalte art, hvor sylinderen på den ene side er svingbar om en i et fast lager i maskinrammen lagret akseltapp hvis akse skjærer eller krysser sylinderaksen i et punkt mellom sylinderens ender, og på den annen side om en aksel på sylinderen som er vinkelrett på denne akseltapp og sylinderaksen. The two cylinder suspensions described above require that either one or two pins or two bearings are attached to the cylinder itself, which can only be done by welding if you want to avoid expensive special design of the cylinder. However, heating the cylinder during welding leads to a deformation of the cylinder, so that the cylinder barrel must then be subjected to post-processing for straightening. This operation entails significant additional costs, and the main purpose of the invention is to avoid such costs with a cylinder suspension device of the type discussed here, where the cylinder is pivotable on the one hand about an axle pin stored in a fixed bearing in the machine frame if axis intersects or crosses the cylinder axis at a point between the ends of the cylinder, and on the other hand about an axis on the cylinder that is perpendicular to this pivot and the cylinder axis.

Ifølge oppfinnelsen har man oppnådd dette ved å anordne akselen på sylinderen i et hode som er forbundet med sylinderens øvre ende og ved å forsyne den i rammen lagrede akseltapp med en arm som strekker seg langs sylinderen og som ved sin ytre ende er anordnet til å oppta den i sylinderhodet anordnede aksel. According to the invention, this has been achieved by arranging the axle on the cylinder in a head which is connected to the upper end of the cylinder and by supplying the axle pin stored in the frame with an arm which extends along the cylinder and which at its outer end is arranged to receive the shaft arranged in the cylinder head.

Armen er hensiktsmessig utført med U-formet tverrsnitt og er fortrinnsvis anordnet slik at den fra tre sider omslutter den del av sylinderen langs hvilken den strekker seg. Ved denne anordning oppnås at armen både får den nødvendige stivhet og bare opptar ubetydelig ekstra plass. Vi-dere kan hullene for akselen i sylinderhodet anbringes direkte i U-seksjonens flenser. The arm is suitably made with a U-shaped cross-section and is preferably arranged so that it encloses from three sides the part of the cylinder along which it extends. With this device, it is achieved that the arm both gets the necessary stiffness and only takes up negligible extra space. In addition, the holes for the shaft in the cylinder head can be placed directly in the flanges of the U-section.

Oppfinnelsen skal forklares nærmere ved hjelp av et eksempel under henvisning til tegningene, hvor fig. 1 viser i perspektiv; en beltetraktor med påmontert skuffeblad og tilhørende hydrauliske manøvrerings-sylindre med opphengningsanordninger ifølge oppfinnelsen, og fig. 2 viser i større målestokk i perspektiv en sylinder med opphengningsanordning. The invention shall be explained in more detail by means of an example with reference to the drawings, where fig. 1 shows in perspective; a crawler tractor with mounted bucket blade and associated hydraulic maneuvering cylinders with suspension devices according to the invention, and fig. 2 shows on a larger scale in perspective a cylinder with a suspension device.

På fig. 1 er vist en beltetraktor 10 som foran er utstyrt med et skuffeblad 11 for utførelse av skuffearbeide. Bladet 11 er på midten ved 13 leddbart lagret på en bære-bøyle hvis to armer strekker seg bakover på hver sin side av traktoren og ved sine bakre ender ved 14 er leddbart lagret på hver sin rammebjelke 15. Skuffebladet 11 er ved begge ender understøttet eller av-stivet ved hjelp av to stenger 16a, 16b som ved sin ene ende er leddbart forbundet med skuffebladet og ved den annen ende er dreibart lagret i et felles lager 17 på bærebøy-lens 12 armer. In fig. 1 shows a crawler tractor 10 which is equipped at the front with a bucket blade 11 for carrying out bucket work. In the middle at 13, the blade 11 is hingedly supported on a support bracket whose two arms extend backwards on each side of the tractor and at its rear ends at 14 is hingedly supported on a respective frame beam 15. The drawer blade 11 is supported at both ends or stiffened by means of two rods 16a, 16b which at one end are hingedly connected to the blade and at the other end are rotatably stored in a common bearing 17 on the arms of the support bracket 12.

For løftning og senkning av bærebøy-lens 12 fremre del og det på bøylen mon-terte skuffeblad 11 ved svingning av bære-bøylen om leddene ved 14, er det på kjent måte anordnet to hydrauliske sylindre 18. Disse sylindre er svingbare i vertikale plan på hver sin side av traktorrammens øvre, fremre del og er i denne hensikt ved hjelp av tapper 19 lagret i hvert sitt lager (ikke vist) under motorpanseret, mens de tilhør-ende stempelstengers 20 ytre ender som er forsynt med hodet 21 ved hjelp av tapper 22 er lagret i lageråpninger 23 i bærebøylen 12. For lifting and lowering the front part of the carrier bracket 12 and the bucket blade 11 mounted on the bracket by swinging the carrier bracket around the joints at 14, two hydraulic cylinders 18 are arranged in a known manner. These cylinders can be pivoted in a vertical plane on each side of the upper, front part of the tractor frame and are for this purpose stored in separate bearings (not shown) under the engine hood by means of pins 19, while the outer ends of the corresponding piston rods 20 which are provided with the head 21 by means of pins 22 is stored in bearing openings 23 in the carrier bracket 12.

Hver tapp 19 bærer ifølge oppfinnelsen en arm 24 som strekker seg fra tappen som sitter i sitt lager på traktoren oppover langs sylinderen 18 til sylinderens øvre en-de. Armen 24 er ifølge eksemplet utført med U-formet tverrsnitt slik at den danner en kanal i hvilken sylinderens øvre del strekker seg slik at den er omgitt av armen på tre sider. Ved armens øvre ende er sideflensene utformet med åpninger 25 som er i flukt med hverandre for anbringelse av en aksel 26 som også strekker seg gjen-nom et hodestykke 27 som er anbragt på According to the invention, each pin 19 carries an arm 24 which extends from the pin which sits in its bearing on the tractor upwards along the cylinder 18 to the upper end of the cylinder. According to the example, the arm 24 is made with a U-shaped cross-section so that it forms a channel in which the upper part of the cylinder extends so that it is surrounded by the arm on three sides. At the upper end of the arm, the side flanges are designed with openings 25 which are flush with each other for the placement of a shaft 26 which also extends through a head piece 27 which is placed on

(sylinderens øvre ende. Akselen 26 er anordnet vinkelrett på sylinderens akse og tappen 19, og den beskrevne opphengning tillater derfor at sylinderen 18 både kan dreies om tappen 19 i et vertikalplan for manøvrering av skuffebladet 11 og om akselen 26 i et skråplan som er vinkelrett på det førstnevnte vertikalplan, hvor planets helling er avhengig av dreiningen om tappen 19 og tjener til å nedsette påkjennin-gene ved støtvis skråbelastning på skuffebladet. (the upper end of the cylinder. The shaft 26 is arranged perpendicular to the axis of the cylinder and the pin 19, and the described suspension therefore allows the cylinder 18 to be turned both about the pin 19 in a vertical plane for maneuvering the bucket blade 11 and about the shaft 26 in an inclined plane which is perpendicular on the first-mentioned vertical plane, where the inclination of the plane depends on the rotation about the pin 19 and serves to reduce the stresses caused by shock-like oblique loading on the blade.

Ved 28 er på tegningen vist en plate som beskytter den del av stempelstangen 20 som stikker ut av sylinderen mot stenslag. Slike beskyttelsesplater er i og for seg kjent, men ved en lagring av sylinderen i en gaffel på den i innledningen beskrevne måte har det ikke vært mulig med slike plater å oppnå en effektiv beskyttelse av de øvre deler av stempelstengene når de er skjøvet helt ut. Gjøres nemlig beskyttelsesplaten så lang at den dekker helt den fullstendig utskjøvne stempelstang, må dens øvre ende for å kunne passere over den på sylinderens overside beliggende gaf-felarm når stempelstangen skyves inn, leg-ges i så stor avstand fra stempelstangen at platens beskyttelsesvirkning i det minste blir illusorisk. Ofte har man derfor istedet avkortet beskyttelsesplaten slik at den ved inntrukket stempelstang ikke når opp til gaffelen og følgelig blir den øvre del av stempelstangen helt ubeskyttet når stempelstangen er skjøvet helt ut. Ved opp-hengningsanordningen ifølge oppfinnelsen opptar derimot armen 24 som svarer til den kjente gaffel bare et forholdsvis ubetydelig rom på sylinderens 18 overside, hvilket stort sett ikke krever noen økning av av-standen mellom beskyttelsesplaten og stempelstangen 20 utover den minimale avstand som er nødvendig for at den skal kunne passere det ved sylinderens nedre ende anbragte sylinderlokk 29 med tilhør-ende festeflens 30. Oppfinnelsen tillater således anvendelsen av en beskyttelsesplate 28, som strekker seg fra sitt feste på stempelstanghodet 21 over hele den ut-skyvbare del av stempelstangen 20 i en konstant ved sylinderens dimensjon bestemt minimumsavstand fra stempelstangen og skaffer dermed en tilfredsstillende beskyttelse for hele den del av stempelstangen som er utsatt for stenslag. At 28, the drawing shows a plate which protects the part of the piston rod 20 which protrudes from the cylinder against stone impact. Such protective plates are known in and of themselves, but when storing the cylinder in a fork in the manner described in the introduction, it has not been possible with such plates to achieve effective protection of the upper parts of the piston rods when they have been fully pushed out. Namely, if the protective plate is made so long that it completely covers the completely extended piston rod, its upper end, in order to be able to pass over the fork arm located on the upper side of the cylinder when the piston rod is pushed in, must be placed at such a large distance from the piston rod that the protective effect of the plate in the the smallest becomes illusory. Often the protective plate is therefore instead cut short so that when the piston rod is retracted it does not reach the fork and consequently the upper part of the piston rod is completely unprotected when the piston rod is pushed all the way out. In the suspension device according to the invention, on the other hand, the arm 24 which corresponds to the known fork only occupies a relatively insignificant space on the upper side of the cylinder 18, which generally does not require any increase in the distance between the protective plate and the piston rod 20 beyond the minimal distance necessary for that it should be able to pass the cylinder cover 29 with associated fastening flange 30 placed at the lower end of the cylinder. The invention thus allows the use of a protective plate 28, which extends from its attachment to the piston rod head 21 over the entire extendable part of the piston rod 20 in a constant minimum distance from the piston rod determined by the cylinder's dimensions and thus provides satisfactory protection for the entire part of the piston rod that is exposed to stone impact.
