CLASS INTERNATIONAL SWEDISH B65 g81 e: 108 PATENT AND REGISTRATION AGENCY Ans. 297/1963 was received on 11/1 1963 issued on 18/10 196 M VIGBORG, UPPSALA Dozer and loader for trucks, tractors and similar vehicles The present invention relates to a dozer and loader for trucks, tractors and similar vehicles, and the object of the invention is that provide a constructively simple, robust and operational attachment device, with the aid of which a loading or towing vehicle can perform simple excavation work and at the same time load itself or a connected slap .. vehicle without the need for a forward and rearward rolling movement during said work.

Apparaten enligt uppfinningen är av det slag, vid vilken mellan tvenne pa var sin sida om fordonet placerade och kring en. i forhallande till fordonet tvargaende axel svangbara armar är uppburen en skopa e. dyl. som med armarnas hjalp ãr svangbar Over fordonet i dess langdriktaing i och far avlaggning av en. fran marken upphamtad last pa ett flak e. dyl. pa fordonet eller pa en till fordonet kopplad slapvagn. Det for uppfinningen i forsta hand kannetecknande är darvid, att den tvargende svangningsaxeln far skoparmarna är uppburen av en slid, som med hjalp av domkrafter e. dyl. är forskjutbar fram och Ater utefter pa fordonet anordnade styrningar. Den forskjutbara sliden underlattar darvid icke blott utforandet av en effektiv gravrorelse has skopan etc. utan gar det ocksa molligt att anvanda oledade skoparmar, vilket starkt forenklar apparatens konstruktion. The apparatus according to the invention is of the type in which between two on each side of the vehicle are placed and around one. in the relation to the vehicle transversely axle pivotable arms is supported a bucket or the like. which with the help of the arms is swivel over the vehicle in its langdriktaing in and father deposition of a. cargo collected from the ground on a platform or the like. on the vehicle or on a trailer attached to the vehicle. What is primarily characteristic of the invention is that the transverse pivot axis of the bucket arms is supported by a slide, which with the aid of jacks or the like. is slidable forwards and backwards along the guides arranged on the vehicle. The displaceable slide thereby not only facilitates the execution of an effective burial movement has the bucket etc., but it is also possible to use unleaded bucket arms, which greatly simplifies the construction of the apparatus.

Genom uppfinningen astadkommes en schakt- och lastapparat, som aven mojliggar en efterstravad lastfordelning vid skopans tomning pa flaket under lastningen och som kan forses med skopor av manga olika slag allt efter det material, som skall schaktas eller lastas. Skopan behover salunda ieke nadvandigtvis vara forsedd med tata vaggar utan kan vara utformad sasom en grepe eller nagot liknande gallerverk. The invention provides a shaft and loading apparatus which also enables a desired load distribution when the bucket is emptied on the platform during loading and which can be provided with buckets of many different types depending on the material to be excavated or loaded. The bucket thus does not necessarily need to be provided with tat rocks, but can be designed as a handle or somewhat similar grid.

For uppfinningens fortydligande askadliggores pa bifogade ritningar ett utforingsexempel pa schakt- och lastapparaten i starkt schematiserad form, varvid den visade utforingsformen iir anpassad for och monterad vid en lastbil. Med sma forandringar skulle den emellertid lika val kunna anvandas vid en traktor far att mojliggora lastning av en till traktorn kopplad slapvagn pa motsvarande silt. For the purpose of clarifying the invention, an exemplary embodiment of the shaft and loading apparatus is shown in the accompanying drawings in a highly schematic form, the embodiment shown being adapted for and mounted on a truck. With small changes, however, the same choice could be used with a tractor to enable the loading of a trailer coupled to the tractor on the corresponding silt.

Pa ritningen visar fig. 1 en sidovy av lastbilen och lastapparaten med skopan vilande mot marken framfor bilen i ett tillbakadraget lage, fig. 2 visar samma apparatforsedda lastbil med skopan fortfarande vilande mot mar-ken men i ett framskjutet lage relativt lastbilen, och fig. 3 visar skopan upplyft frail marken och redo att fullfolja sin rorelse bakat for att -Lammas Over lastbilens flak — i samma lage kan skopan lampligen lianas da den pa lastbilens flak emottagna och transporterade godsmangden skall avtippas, sasom antytts med punktstreckade linjer. Fig. 1 visar lastapparaten i ett lige, som mojliggor Manning av skopans innehall pa flakets framre del, medan fig. 5 visar lastapparaten i ett annat lage, som mojliggor skopans tomning pa flakets bakre del, och fig. 6 visar det lige, som lastapparaten och skopan lampligen kunna intaga under transport. Fig. 7 visar slutligen en schematisk planvy av lastapparaten sadan den levereras for fastsattning pa undersidan av lastbilens chassi. In the drawing Fig. 1 shows a side view of the truck and the loader with the bucket resting against the ground in front of the car in a retracted position, Fig. 2 shows the same equipped truck with the bucket still resting against the ground but in a projected position relative to the truck, and fig. 3 shows the bucket raised from the ground and ready to complete its movement backwards to -Lammas Over the truck's flatbeds - in the same position the bucket can be conveniently lined as the quantity of goods received and transported on the truck's flatbeds is to be tipped, as indicated by dotted lines. Fig. 1 shows the loader in a straight line, which enables Manning of the contents of the bucket on the front part of the platform, while Fig. 5 shows the loader in another layer, which allows the bucket to be emptied on the rear part of the platform, and Fig. 6 shows the straight line, as the loader and the bucket can be easily taken during transport. Fig. 7 finally shows a schematic plan view of the loader as it is delivered for attachment to the underside of the truck chassis.

En schakt- och lastapparat enligt uppfinningen bestar foretradesvis av en styv ramkonstruktion 1, som Or fast eller anordnad att fastas ph undersidan av en lastbils 2 chassi ungefar under forarhytten. I ramkonstruktionen 1 aro anordnade tva hydrauliska, dubbelverkande domkrafter 3, med vilkas hjalp en slid 4 Or horisontellt forskjutbar fram ocb Ater utefter de framre .partierna 1' av ram- 2. konstruktionens 1 langsgaende delar, vilka tj dna sasoni styrningar for sliden. Sliden 4 fir utford sasom ett lagerhus for en tvargaende svangningsaxel 5, som via utvaxlingsanordningar 6 är roterbar med hj alp av en hydraulisk eller annan motor 7, och vid vars bade, pa omse sidor om lastbilen 2, utskjutande andar aro anbragta tvfi armar 8. Dessa armar 8, som aro inbordes parallella och stracka sig i lastbilens langdriktning, da de aro framfallda enligt fig. 1 och 2, uppbara mellan sina yttre findar en kring en likaledes tvargaende axel 0 svangbar skopa 10, vars vinkellage relativt armarna 8 ar foranderligt under paverkan cv en hydraulisk domkraft 11 vid vane arm. Tryckfluidumtillforseln till de sistnamnda domkrafterna 11 kan med fordel vara tyfingsmassigt reglerad i beroende av armarnas 8 lagen under en del av armarnas svangnings-rorelse for att sakerstalla, att skopan icke -oavsiktligt tommes Over fordonets forarhytt 'under lastningsarbetet. A shaft and loading apparatus according to the invention preferably consists of a rigid frame construction 1, which is fixed or arranged to be attached to the underside of a truck 2 chassis approximately below the cab. Arranged in the frame structure 1 are two hydraulic, double-acting jacks 3, with the aid of which a slide 4 is horizontally displaceable forwards and backwards along the front portions 1 'of the longitudinal parts of the frame structure 1, which serve as soni guides for the slide. The slide 4 is challenged as a bearing housing for a transverse pivot shaft 5, which can be rotated via gearing devices 6 by means of a hydraulic or other motor 7, and at whose baths, on opposite sides of the truck 2, projecting spirits are arranged two arms 8. These arms 8, which are embedded in parallel and extend in the longitudinal direction of the truck, as they protrude according to Figs. 1 and 2, carry between their outer ends a bucket 10 pivotable about an equally transverse axis 0, the angular position of which relative to the arms 8 is variable below impact cv a hydraulic jack 11 at habit arm. The supply of pressure fluid to the latter jacks 11 can advantageously be regulated in terms of tying in dependence on the law of the arms 8 during a part of the pivoting movement of the arms to ensure that the bucket is not inadvertently emptied over the vehicle's driver's cab during loading.

Armarna 8 Oro lampligen fast men lOstagbart anbragta, exempelvis med hj alp av bult-fOrband sfisom antytts, vid sarskilda andstyelen pa axeln 5, sâ att armarna och dfirined naturligtvis aven skopan 10 kunna losgOras Iran lastbilen, dá denna skall anvandas for sh-dana transportuppgifter, dá lastapparaten icke behovs. Ramen 1 med sliden 4 hanger dfi lampligen kvar under lastbilens chassi for att underlatta en atermontering av armarna och 'skopan. The arms 8 are suitably fixed but releasably mounted, for example by means of bolted joints as indicated, at the separate end pieces on the shaft 5, so that the arms and of course also the bucket 10 can be detached from the Iran truck, as this is to be used for transport purposes. , when the loader is not needed. The frame 1 with the slide 4 is conveniently hung under the truck chassis to facilitate reassembly of the arms and bucket.

For att sliden 4 icke skall snedstfilla sig och karva under sina r8relser i ramen 1, aven om tryckfluidumtillforseln till de hada visade domkrafterna 3 skulle vara oregelbunden, fir sliden 4 forsedd med en styranordning i form -av en vid sliden fritt roterbart lagrad tvargaende axel 12, som i sina bade andar har kuggljul 13, vilka samverka med kuggstangslikUande delar '14 ph ramens 1 framre styrpartier 1'. Kuggstangsdelarna 14 kunna sj filvfallet fistadkommas med hjalp av kedjor, som "aro straekta utefter styrpartiernai vilket .fall kugghjulen 13 utbytas mot kedjehjul pfi och for sig kfint sad. In order for the slide 4 not to skew and carve during its movements in the frame 1, even if the pressure fluid supply to the jacks 3 shown would be irregular, the slide 4 is provided with a guide device in the form of a transverse shaft 12 freely rotatably mounted on the slide. , which in their bathing spirits have gears 13, which cooperate with rack-like parts '14 ph of the front guide portions 1 'of the frame 1'. The rack parts 14 can be fitted with the aid of chains which are stretched along the guide portions in which case the gears 13 are exchanged for sprockets pfi and separately finely sad.

Det lir tydligt, att skopan 10, da den vilar mot marken sasom i fig. 1 och 2, kan bi-bringas en fram- och atergaende schaktningseller gravningsrorelse genoth tryckfluidumtillforsel till domkrafternas 3 respektive andar, utan att lastbilen f Or den skull behOver rulla .fram och tillbaka. Sliden 4 ror sig darvid likeledes fram och tillbaka utefter styrningarna 1'. Uppsvfingning eller lyftning av skopan kan 'med hydraulmotorns 7 hjalp ske i vilket som "heist lage for sliden 4, och beroende ph slidens och armed svangningsaxelns 5 lage kan -skopan 10 enligt fig. 4 resp. 5 t6mmas an tingen Over flakets 2' framre eller bakre del, varigenom en idealisk lastfordelning kan sakerstallas pa lastbilen 2. Den forskjutbara svangningsaxeln 5 fyller salunda en funktion icke blott under schaktning och skopfyllning utan aven under skopans tomning Over flaket. It is clear that the bucket 10, as it rests against the ground as in Figs. 1 and 2, can be provided with a reciprocating excavation or digging motion by supplying pressure fluid to the respective spirits of the jacks 3, without the truck having to roll for that reason. back and forth. The slide 4 then also moves back and forth along the guides 1 '. Swinging or lifting of the bucket can, with the help of the hydraulic motor 7, take place in any position of the slide 4, and depending on the position of the slide and the armed pivot shaft 5, the bucket 10 according to Figs. 4 and 5, respectively, can be emptied over the front of the platform 2 or rear part, whereby an ideal load distribution can be stored on the truck 2. The displaceable pivot shaft 5 thus fulfills a function not only during excavation and bucket filling but also during the bucket emptying above the surface.

Armarna 8 maste naturligtvis vara utformade pa sadant satt att de kunna passera utanfor saval forarhyttens som flakets 2' langsgfiende sidor yid lastningsarbetet. Under transport kan skopan lampligen med armarnas hj alp plaeeras ovanpa det lastade flaket shsom fig. 6 visar. Nan flaket skall tommas genom tippning bakht, svanges skopan lamplig,en nagot framat till det i fig. 3 visade lfiget, dar forarhyttens sidodorrar joke blockeras av armarna 8 utan fritt kunna oppnas i och for kontroll av tippningsarbetet. Naturligtvis blockeras icke heller hyttdorrarna under Schaktnings- och gravningsarbetet tack vare apparatens utformning och placering. The arms 8 must of course be designed in such a way that they can pass outside the longitudinal sides of both the cab and the platform 2 'during the loading work. During transport, the bucket can suitably be placed with the aid of the arms on top of the loaded platform as shown in Fig. 6. When the flatbed is to be emptied by tilting backwards, the bucket is swung lampily, slightly forward to the body shown in Fig. 3, where the driver's side doors joke are blocked by the arms 8 but can be freely opened in and for control of the tilting work. Of course, the cab doors are not blocked during the excavation and excavation work either, due to the design and location of the device.

Tryckfluidumtillforseln sfival till domkrafterna 3 som den hydrauliska drivmotorn 4 och domkrafterna 11 regleras lampligen, dock 10- retradesvis med forutnamnda undantag, pa .vanligt satt manuellt Iran forarhytten. Det moter emellertid intet hinder, att manovreringen alternatiyt sker &fin en manovercentral ph' lastbilens utsida. Nar schaktning eller last-fling skall utforas, fastbromsas naturligtvis fordonet, medan dess motor ffir fortsatta aft arbeta pfi en icke visad hydraulpump, som tjanstgor sfisom tryckkalla for domkrafterna 3 och 11 saval som for hydraulmotorn 7. For-don ets hale drivmotoreffekt kan dfi utnyttjas Ilk gray- och lastfunktionen, om s erfordras. The supply of pressurized fluid to the jacks 3 such as the hydraulic drive motor 4 and the jacks 11 is suitably regulated, but 10 respectively with the aforementioned exceptions, in the usual manual manual Iran cab. However, there is no obstacle to the maneuvering alternatively taking place outside the control center ph 'of the truck. When excavation or load-flaking is to be carried out, the vehicle is of course braked, while its engine continues to operate on a hydraulic pump (not shown), which serves as a pressure coil for the jacks 3 and 11 as well as for the hydraulic engine 7. Ilk gray and load function, if required.

Uppfinningen fir givetvis icke begransad till det visade exemplets detaljutformning. Shinnda kunna armarna 8 yam syfingbara kring mot svangningsaxeln 5 svarande svangningstappar ph sliden 4 och manovreras med sar.skilda domkrafter placerade mellan armarna och sliden istallet for med hydraulmotorn 7. Joke heller behover skopan vara lagrad direkt -mellan armarnas ytterandar sasom visats, ehuru detta ur konstruktiv synpunkt fir det enklaste. Aven andra detaljmodifikationer aro tankbara, utan att ramen fOr de efterfoljande 'patentanspraen oyerskrides. The invention is of course not limited to the detailed design of the example shown. Shinnda the arms 8 yam can be seen around the pivots 4 corresponding to the pivot shaft 5 and are maneuvered with special jacks placed between the arms and the slide instead of with the hydraulic motor 7. Joke also needs the bucket to be mounted directly - between the outer ends of the arms as shown, constructive point of view for the simplest. Other detailed modifications are also conceivable, without exceeding the scope of the subsequent patent claims.
