KLASS INTERNATIONELLSVENSK B6g81 e:107 PATENT- OCH REGISTRERINGSVERKET Ans. 658/1961 den 23/1 1961Hartill en riffling R HEGG, SVINEVOLL, NORGE Anordning vid motorfordon med lyftgaffel Foreliggande uppfinning avser ett fordon utrustat med en gaffellyftanordning, vanligen benamnd gaffeltruck. CLASS INTERNATIONAL SWEDISH B6g81 e: 107 PATENT AND REGISTRATION AGENCY Ans. The present invention relates to a vehicle equipped with a fork lift device, commonly referred to as a forklift truck.

Det är tidigare kant vid fordon av detta slag att utrusta desamma med motvikter, som aro anordnade rorliga i fordonets lfingdriktning vid den fran gaffellyftanordningen vettande anden for att kunna mojliggora en 8kad lyftkapacitet och lyfthojd av gaffeln utan risk for att fordonet skall vippa kring den anliggande hjulaxeln. It is previously the case with vehicles of this type to equip them with counterweights which are arranged movable in the direction of movement of the vehicle at the spirit facing away from the fork lift device in order to enable an increased lifting capacity and lifting height of the fork without risk of the vehicle tilting around the adjacent axle. .

Andamblet med foreliggande uppfinning dr att astadkomma ett fordon av ovan angivet slag, genom vilket den onskade okningen i lyftkapacitet och lyfthojd kan uppnas Man. anvandning av sarskilda motvikter som 8kar fordonets totala vikt. The object of the present invention is to provide a vehicle of the type indicated above, by means of which the desired increase in lifting capacity and lifting height can be achieved. use of special counterweights that increase the total weight of the vehicle.

Enligt foreliggande uppfinning uppnas detta genom att anordna fordonets drivmotor for att kunna tjana sasom fi5rstallbar motvikt forflyttbar under vanlig drift i langdriktningen av chassiets ram. Motorn kan vara lagrad begransat forskjutbar 1 en forlangningsram, som är lagrad forskjutbart i chassieramens la.ngdriktning pd sadant satt att motorn kan foras helt eller delvis utanfor den bakre anden av chassieramen. According to the present invention, this is achieved by arranging the drive motor of the vehicle in order to be able to serve as a manufacturable counterweight movable during normal operation in the longitudinal direction of the chassis frame. The motor may be mounted in a limited displaceable manner in an extension frame, which is mounted displaceably in the longitudinal direction of the chassis frame in such a way that the motor can be guided completely or partially outside the rear spirit of the chassis frame.

En utforingsform av uppfinningen visas sdsom exempel pa ritningen, van i fig. 1 visar en schematisk vy fran sidan av ett fordon enligt uppfinningen och fig. 2 visar en tvdrsekton genom chassieramens ena sidoparti. An embodiment of the invention is shown as an example in the drawing, shown in Fig. 1 showing a schematic side view of a vehicle according to the invention and Fig. 2 showing a cross section through one side portion of the chassis frame.

Ph ritningen betecknar 1 chassieramen, som pa vanligt salt ar utrustad med framhjul 2 och bakhjul 3. I den visade utforingsformen aro bakhjulen 3 utforda sasom styrhjul, under det att framhjulen 2 aro forbundna med differentialaxeln 4, som drives medelst en omkastningsbar hydraulisk motor 5. Vid den framre anden uppbar ramen 1 pelarna A for den hydrauliska lyftgaffeln (icke visad), vilka pelare pa kant salt aro fasta vridbart kring en horisontal axel. In the drawing, 1 denotes the chassis frame, which on ordinary salt is equipped with front wheels 2 and rear wheels 3. In the embodiment shown, the rear wheels 3 are like steering wheels, while the front wheels 2 are connected to the differential shaft 4, which is driven by a reversible hydraulic motor 5. At the front end, the frame 1 carried the pillars A of the hydraulic lifting fork (not shown), which pillars on the edge of the salt are fixed rotatably about a horizontal axis.

Drivmotorn bestar av ett aggregat 6, som omfattar en forbranningsmotor och en av derma driven hydraulisk pump, som avgiver tryckvatska till fordonets olika hydrauliska drivanordningar. The drive motor consists of a unit 6, which comprises an internal combustion engine and a hydraulic pump driven by it, which delivers pressure water to the various hydraulic drive devices of the vehicle.

I chassieramens 1 kanalformade sidopartier ar forskjutbart lagrad en forlangningsram 7, som uppbar aggregatet 6. Ramen 7 liar likaledes kanalformad tvarsektion, vani vridbara lagringsrullar 8, som aro fasta vid aggregatet 6, griper in och kan rulla i ramens langdriktning, varvid dess andstycken 7' begransar rullarnas. 8 rorelse. Vid denna anordning kan sasom inses aggregatet 6 forskjutas i ramens 1 langdriktning fran det pa ritningen med streckpunkterade linjer visade laget, van i vikten fordelas, pa hada axlarna och till det med heldragna linjer visade laget, van i aggregatet 6 är fort utanfor bakaxeln pa sadant son, all det utOvar silt Tr' mala motviktsmoment far den vid fordonets framre ande monterade lyftgaffeln. In the channel-shaped side portions of the chassis frame 1, an extension frame 7 is slidably mounted, which supports the assembly 6. The frame 7 also has a channel-shaped cross section, of rotatable bearing rollers 8, which are fixed to the assembly 6, engages and can roll in the longitudinal frame of the frame. borders the rollers. 8 rorelse. In this device, as can be seen, the assembly 6 can be displaced in the longitudinal direction of the frame 1 from the layer shown in the drawing with dash-dotted lines, the weight is distributed on the shoulders and to the layer shown in solid lines, the assembly 6 is fast outside the rear axle. son, all the utOvar silt Tr 'grinding counterweight moment far the lifting fork mounted at the front of the vehicle.

For att forskjuta aggregatet 6 nod eller titan forlangningsram 7 ãr mellan en fran aggregatet nedskjutande arm 9 och ramen 1 anordnad en dubbelverkande teleskapformad hydraulisk drivcylinder 10, som fir ansluten till trycksystemet genom en vanlig styrventil. To displace the unit 6, a node or titanium extension frame 7 is arranged between an arm 9 projecting from the unit and the frame 1, a double-acting telescopic hydraulic drive cylinder 10 is arranged, which is connected to the pressure system by means of a standard control valve.

For att kunna korta av fordonets axelavstand kan bakaxeln 3a vara monterad pd fdrlangningsramen 7 pa sadant salt, att den kan fiirflyttas tillsammans med denna:. In order to be able to shorten the wheelbase of the vehicle, the rear axle 3a can be mounted on the extension frame 7 on such a salt that it can be moved together with it :.
