Anordning vid fordon, speciellt sadana som aro avsedda for horning pa obanad mark. Devices for vehicles, in particular those intended for horning on unpaved ground.
Foreliggande uppfinning avser en anordning vid fordon, speciellt sadana som aro avsedda for korning over ,obanad mark. Vid dylika fordon är det onskvart, att de barande .organen, t. ex. hjul, krypkedjor med drivhjul och runar, eller dylikt, besitta erforderlig rot.- lighet for att medgiva en jamn lastfordelning, samtidigt som lasten skall deltaga sa litet som mOjligt i barorganens rOrelser. Det bar redan foreslagits, att lata fordonskroppen helt uppbaras av tvenne vid var sin sida oin fordonskroppen vid densamma svangbart lagrade ramar eller armar, i vilka fordonets samtliga bar- och/eller drivhjul aro roterbart lagrade med minst tvenne hjul 1 varje ram. The present invention relates to a device for vehicles, in particular those intended for grain over unpaved ground. In the case of such vehicles, it is undesirable that the load-bearing means, e.g. wheels, creep chains with drive wheels and runes, or the like, possess the necessary root capacity to allow an even load distribution, while the load must participate as little as possible in the movements of the bar members. It has already been proposed that the lazy vehicle body be fully supported by two at each side of the vehicle body at the same pivotally mounted frames or arms, in which all bar and / or drive wheels of the vehicle are rotatably mounted with at least two wheels in each frame.
Foreliggande uppfinning kanneteeknas huvudsakligen darav, att ramarna aro forsedda med i fordonskroppen lagrade i densamma inskjutande svangtappar, vilka svangtappar aro sammankopplade inbordes och med fordonskroppen medelst en utjamningsanordning pa sadant satt att en vridning av den ena ramen relativt fordonskroppen i en riktning astadkornmer en vridning av den .andra ramen relativt fordonskroppen i motsatt riktning, vilken anordning är forlagd helt mutt fordonskroppen och har till ,andamal att utjamna hjulens rorelser. The present invention is mainly characterized in that the frames are provided with in the vehicle body mounted in the same projecting pivot pins, which pivot pins are interconnected inboard and with the vehicle body by means of a leveling device such that a rotation of one frame relative to the vehicle body in a direction the second frame relative to the vehicle body in the opposite direction, which device is located completely opposite the vehicle body and has the purpose of smoothing the movements of the wheels.
Denna anordning gOr det mojligt att utfora fordonskroppens botten med slat undersida saledes utan nagra utstaende delar, som kunna fastna mot stubbar eller stenar ph mar-ken, varigenom fordonets fOrmaga att taga sig fram i obanad terrang Ras. Vidare uppnas den fordelen, att utjamningsanordningen val skyddas saval Iran att skadas genom stOtar och dylikt som aven mot smuts ,och damm under korningen. Dessutom kunna forbindningarna mellan utjamningsanordningen och ramamas svangtappar utforas pa enklaste .och mest effektiva salt, och det är icke nodvandigt att anvanda sarskilda vridningstappar for utjamningsanordningen I fordonskroppen .och sarskilda tatningsanordningar f Or desamma. En ytterligare fordel är, att -utjamningsanordningen latt kan utforas sA, att den medgiver obegransad vridning av ramarna i forhallande till fordonskroppen. This device makes it possible to make the bottom of the vehicle body with a slippery underside thus without any protruding parts, which can get stuck against stumps or stones in the ground, whereby the vehicle's ability to get out into unpaved terrain Ras. Furthermore, the advantage is achieved that the equalization device choice is protected saval Iran to be damaged by stOtar and the like as well as dirt, and dust during the grain. In addition, the connections between the leveling device and the frame pivot pins can be made on the simplest and most efficient salt, and it is not necessary to use special pivot pins for the leveling device in the vehicle body and special sealing devices for the same. A further advantage is that the leveling device can be easily designed so that it allows unlimited rotation of the frames in relation to the vehicle body.
Uppfinningen giver vidare en sarskild f Or-del darigenom, att utjamningsanordningen latt kan goras pa sadant satt installbar i forhallande till fordonskroppen, att genom installning av densamma fordonskroppen kan vridas och installas i forhallande till de hada ramarna .omkring dessas svangtappar utan andring av ramarnas inbordes lage, varigenom man saledes kan installa fordonskroppens lage i forhallande till markytan. The invention further provides a special advantage in that the leveling device can easily be made so that it can be installed in relation to the vehicle body, that by installing the same vehicle body it can be rotated and installed in relation to the had frames around their pivot pins without changing the frames inside. layer, whereby one can thus install the vehicle body layer in relation to the ground surface.
PA bifogade ritningar askadliggores sasom exempel och schematiskt nagra olika utf0- ringsformer av anordningar enligt foreliggande uppfinning. The accompanying drawings are illustrated by way of example and schematically illustrate various embodiments of devices of the present invention.
Fig. 1 visar en planvy av en traktor, vid vilken utjamningsanordningen bestar av en differentialkuggvaxel. Fig. 2 visar en sidovy av traktorn. Fig. 3 visar en planvy av en traktor eller annat fordon med ett annat utforande .av utjamningsanordningen. Fig. 4 visar ett utforande av en traktor, vid vilken utjarnningsanordningen ar installbar i forhallande till fordonskroppen. Fig, 5 och 6 visa i planvy ytterligare tvenne utfOringsformer. Fig. 7 visar en planvy av ett annat utforande av en traktor, vid vilken ramarna aro svangbara omkring en axellinje, som sammanfaller med traktorns langdaxel. Fig. 1 shows a plan view of a tractor, in which the leveling device consists of a differential gear. Fig. 2 shows a side view of the tractor. Fig. 3 shows a plan view of a tractor or other vehicle with a different embodiment of the leveling device. Fig. 4 shows an embodiment of a tractor, in which the leveling device can be installed in relation to the vehicle body. Figs. 5 and 6 show in plan view two further embodiments. Fig. 7 shows a plan view of another embodiment of a tractor, in which the frames are pivotable about an axis line, which coincides with the long axis of the tractor.
Vid den i fig. 1 .och 2 schematiskt visade traktorn betecknar 1 fordonskroppen, i vilken tvenne ramar 2 Oro svangbart upphangda medelst svangtapparna 3, sa. att de kunna svangas i forhallande till fordonskroppen. I varje ram 2 aro tvenne barhjul 4 lagrade. Dessa barhjul 4 aro i detta fall a.'ven drivhjul. Drivkraften overfores pa i och for sig kant satt fran motoraggregatet 5, vilket innefattar motor med koppling och vaxellada, genom en kuggvaxel 6 till tvenne med styrbromsar 7 forsedda styrkopplingar 8, fran var och en av vilka drivkraften Overfores genom en kraftoverf5ringsanordning 9, t. ex. kedjevaxlar och mellanaxlar, till en i vardera svangtappen 3 lagrad axel 10 och frail denna genom kedjor 11 till drivhjulens 4 axlar. In the tractor schematically shown in Figs. 1 and 2, 1 denotes the vehicle body, in which two frames 2 are pivotally suspended by means of the pivot pins 3, sa. that they can be swung in relation to the vehicle body. In each frame 2, two bar wheels 4 are stored. These bar wheels 4 are in this case also drive wheels. The driving force is transmitted per se from the motor unit 5, which comprises motor with clutch and gearbox, through a gear shaft 6 to two control clutches 8 provided with steering brakes 7, from each of which the driving force is transmitted through a power transmission device 9, e.g. . chain shafts and intermediate shafts, to a shaft 10 mounted in each pivot pin 3 and frail it through chains 11 to the shafts of the drive wheels 4.
I detta fall utgores utjamningsanordningen av en differentialkuggvaxel, vilken befinner sig mom fordonskroppen eller i ett kapslat 2— 12&044 — rum i denna, och vars ytterhjul 12 aro anbragta pa svangtapparna 3, under det att mellanhjulet eller -hjulen 13 aro anordnade pa en eller, flera i fordonskroppen lagrade axlar 14. Del inses latt, att denna utjamningsanordning medgiver obegransad vridning av ramarna 2 i forhallande till fordonskroppen 1, sá .att saledes harhjulen obehindrat kunna inStatla sig efter markytan. Samtidigt bestammer utjananingsanordningen fordonskroppens lage i forhallande till ramarna .och barhjulen. Fordonskroppen kommer namligen, sasom latt inses, att intaga ett vridningslage omkring tapparna 3 mitt• emellan ramarna 2, d. v. s, i bisektriSen till den vinkel, som ramama bilda med varandra. In this case the leveling device consists of a differential gear, which is located between the vehicle body or in a enclosed 2-12 & 044 - space therein, and whose outer wheels 12 are arranged on the pivot pins 3, while the intermediate wheel or wheels 13 are arranged on one or, several shafts 14 stored in the vehicle body. It is easily understood that this leveling device allows unlimited rotation of the frames 2 in relation to the vehicle body 1, so that the hair wheels can thus move unhindered to the ground surface. At the same time, the leveling device determines the condition of the vehicle body in relation to the frames and the bar wheels. Namely, as will be readily appreciated, the vehicle body will assume a direction of rotation about the pins 3 midway between the frames 2, i.e., in the bisector at the angle which the frames form with each other.
For att vid hastig vridning av nagon av mamarna minska den stOt, som harvid 5verfores till fordonskroppen, ãr det lampligt .att utfora utjamningsanordningen fjadrande. Detta kan vid denna utforingsform av utja.mningsanordningen ldtt astadkommas genom en fjadrande lagring av axeIn 14 f5r raellanhjulet 13, sa.- som schematiskt visas i fig. 2, dar axeln 14 visas Tara uppburen av i fordonskroppen inspanda fjadrar 15. In order to reduce the impact which is then transferred to the vehicle body in the event of rapid rotation of any of the moms, it is appropriate to make the leveling device resilient. In this embodiment of the leveling device this can easily be achieved by a resilient bearing of the axle 14 for the main wheel 13, as schematically shown in Fig. 2, where the axle 14 is shown Tara supported by springs 15 clamped in the vehicle body.
Den i fig. 3 visade utforingsformen skiljer sig frau den ovan beskrivna blott darigenom, att differentialkuggvaxelns ytterhjul 12 icke Oro direkt a.nbragta pa ramarnas 2 svangtappar 3 utan aro forbundna med dessa medelst kedjevaxlar 16 med nagot lampligt utvaxlingsfOrhallande. The embodiment shown in Fig. 3 differs from the one described above only in that the outer gear 12 of the differential gear is not directly mounted on the pivots 3 of the frames 2 but is connected to them by means of chain shafts 16 with a somewhat suitable gear ratio.
Den i fig. 4 visade utforingsformen overensstammer satillvida med den i fig. 3 visade, som ramarnas 2 svangtappar 3 aro genom kedjevaxlar 16 forbundna med ytterhjulen 12 I differentialkuggvaxeln. Axeln 14 till differentialkuggvaxelns mellanhjul 13 ar emellertid i detta fall lagrad i en ram eller ett holje 17, vilket am vridbart omkring ytterhjulens 12 gemensamma vridningsaxellinje, .och som är forbundet riled ett skruvhjul 18, i vilket in-griper en skruv 19, som är vridbart lagrad i fordonskroppen 1, och som kan vridas medelst lamplig anordning, sasom schematiskt antydes av veven 20. Vid vridning av skruven 19 i den ena eller andra riktningen kommer sale-des skru-vhjulet 18 och darigenom holjet 17 med mellanhjulen 13 att vridas omkring ytterhjulens 12 vridningsaxellinje, varvid dessa ytterhjul 12 liven vridas i forhallande till fordonskroppen. Eftersom harhjulen 4 i ramarna 2 sta. ph markytan, sh att ramarna 2 icke kunna vrida sig, kommer i stallet fordonskroppen 1 att vrida sig i ena eller andra riktningen omkring svangtapparna 3 i forhallande till ramarna 2 .och barhjulen 4. Medelst den besIKrivna installningsanordningen kan man saledes hoja eller sanka fordonskroppens framre ande i fOrhallande till m.arkytan, varvid givetvis doss hakre ande samtidigt sankes eller hojes. Denna anordning gOr det darfor majligt att direkt ph fordonskroppen 1 an bringa sadana arhetsredskap, t. ex. schaktblad 21, rivare eller dylikt, vilka under arbetet maste hops och sdnkas i forhallande till marken. The embodiment shown in Fig. 4 corresponds in parallel with that shown in Fig. 3, as the pivot pins 3 of the frames 2 are connected by chain shafts 16 to the outer wheels 12 of the differential gear shaft. However, the shaft 14 of the differential gear intermediate gear 13 is in this case mounted in a frame or housing 17, which is rotatable about the common axis of rotation of the outer wheels 12, and which is connected to a screw wheel 18, in which engages a screw 19 which is rotatably mounted in the vehicle body 1, and which can be rotated by means of a lamp device, as schematically indicated by the crank 20. When turning the screw 19 in one or the other direction, the screw wheel 18 and thereby the casing 17 with the intermediate wheels 13 will be rotated about the axis of rotation of the outer wheels 12, these outer wheels 12 rotating the webs in relation to the vehicle body. Since the hair wheels 4 in the frames 2 sta. ph the ground surface, that the frames 2 cannot turn, will instead of the vehicle body 1 rotate in one or the other direction around the pivots 3 in relation to the frames 2 and the bar wheels 4. By means of the described installation device one can thus raise or lower the front of the vehicle body. spirit in relation to the surface of the earth, whereby of course doss hooked spirit is simultaneously sunk or raised. This device therefore makes it possible to bring such vehicle equipment directly to the vehicle body 1, e.g. dozer blades 21, shredders or the like, which during the work must be piled up and sunk in relation to the ground.
Aven vid den i fig. 4 visade utforingsformen am det givetvis mojligt .att utfora utjamnings, anordningen fjadrande. Man kan exempelvis anordna en fjadrande lagring for axeln 14 i ramen 17, eller skruven 19 kan vara fjadrande uppburen i fordonskroppen pa .sa.d.ant satt, att den är mom vissa granser rorlig i sin langdriktning. Dot inses ocksa latt, att den i fig. 1 visade utjamningsanordningen aven kan gOras installbar pa motsvarande salt, som ovan beskrivits Maga om fig. 4. Detta galler awn om de utforingsformer, som beskrivas i det foljande. Even with the embodiment shown in Fig. 4, it is of course possible to make the leveling device resilient. For example, a resilient bearing for the shaft 14 may be provided in the frame 17, or the screw 19 may be resiliently supported in the vehicle body in such a way that it is movable in certain longitudinal directions with certain boundaries. It will also be readily appreciated that the leveling device shown in Fig. 1 may also be made installable to the corresponding salt, as described above in Fig. 4. This applies to the embodiments described in the following.
Vid utfOrandet enligt fig. 5 bestar .utjamningsanordningen. av en differentialvaxel, s.orn utgOres av ett eller flera bojliga organ 22, 1. ex. i form .av kedjor, stallinor eller dylikt, vilka aro forbundna med ran-lama 2, i det visade fallet genom att de lopa Over pa ramarnas 2 svangtappar 3 fasta kedjehjul eller linhjul 23, och vika bojliga organ 22 dessutom lOpa Over ledhjul 24, som aro lagrade i fordonskroppen. De bOjliga organen 22 aro O. lagda Over hjulen pa svangtapparna 3, att parterna air det bojliga organet pa ena sidan av dessa svangtapp.ar, t. ex. paoversidan, ga till ett och samma ledhjul, och parterna pa undersidan till det andra ledhjulet. Harigenom komma ocksa i delta fall ramarna 2 att vara obegransat vridbara i forhallande till' fordonsramen 1, och vid vridning av den ena ramen kommer den .andra ramen att vridas I motsatt riktning i forhallande till fordonskroppen. Ocksa i detta fall kan utjamningsanordningen goras fjadrande eller eftergivande for att minska st5tar pa fordonskroppen genom en fjadrande lagring av ledhjulen, sasom schematiskt antydes vid 25. In the embodiment according to Fig. 5, the leveling device consists. of a differential shaft, s.orn constituted by one or more flexible members 22, 1. ex. in the form of chains, stable ropes or the like, which are connected to the rails 2, in the case shown by running Over on the pivot pins 3 of the frames 2 fixed sprockets or pulleys 23, and folding flexible members 22 in addition to Loop Over guide wheels 24, which are stored in the vehicle body. The flexible members 22 are O. laid over the wheels on the pivot pins 3, that the parties air the flexible member on one side of these pivot pins, e.g. on the upper side, go to one and the same articulated wheel, and the parties on the underside to the other articulated wheel. As a result, also in some cases the frames 2 will be indefinitely rotatable in relation to the vehicle frame 1, and when one frame is rotated the other frame will be rotated in the opposite direction in relation to the vehicle body. Also in this case, the leveling device can be made resilient or resilient in order to reduce shocks on the vehicle body by a resilient bearing of the articulated wheels, as schematically indicated at 25.
Vid det i fig. 6 visade utftirandet utgores utjamningsanordningen av en eller flera tvOarmade havstanger 26, varav tva visas ph ritningen, och vilka vardera aro, vid en punkt 27 svangbart lagrade i fordonskroppen 1, under det att varje havstang är pa omse sidor om denna lagringspunkt vid andarna 28 medelst lampligen stela lankar 29 forbun.dna med ramamas 2 svangtappar 3 vid punkterna 30 pa dessa. Dot insos latt, att vid vridning av endera ramen i forhallande till fordonskroppen den andra ramen kommer att vridas, i motsatt riktning i forhallande till denna, sá att fordonskroppen ocksâ i delta fall kommer att intaga ett medelvridningslage mellan ramarna. Havstangerna 26 kunna antingen anhringas i en fjadrande lagring i fordonskroppen, eller de kunna sjalva utforas fjadrande, t. ex. i form av bladfjadrar, sasom schematiskt visas pa ritningen, varigenom utjamningsanordningen aven i detta fall blir fjadrande och stotutjamnande. - -3 Genorn att lankarria 29 fran den ena havstangen 26 aro forbundna med punkter 30 pa undre sidan av svangtapp.arn.a 3 och lankarna 29 fran den andra haystangen 26 aro, forbundna med punkter 30 pa svangtapparnas 3 oversida, utbalanseras de vridande momenten, utan att svangtapparnas lager darav belastas. En snotsvarande utbalansering av momenten kan givetvis aven uppnas vid de ovriga har beskrivna utforingsformerna genom att .anordna f] era utjamningsanordningar symmetriskt i forhalla.nde till svangtapparna. In the embodiment shown in Fig. 6, the leveling device consists of one or more two-armed sea rods 26, two of which are shown in the drawing, and each of which is, at a point 27, pivotally mounted in the vehicle body 1, while each sea rod is on opposite sides thereof. storage point at the spirits 28 by means of suitably rigid links 29 connected to the 2 pivot pins 3 of the frames at the points 30 on these. It is easily understood that when rotating one frame in relation to the vehicle body, the other frame will be rotated, in the opposite direction relative to it, so that the vehicle body will also in some cases assume an average rotational law between the frames. The sea rods 26 can either be fastened in a resilient bearing in the vehicle body, or they can themselves be made resilient, e.g. in the form of leaf springs, as schematically shown in the drawing, whereby the leveling device also in this case becomes resilient and shock-leveling. - -3 The girders 29 of the sea rod 26 from one of the sea rods 26 are connected to points 30 on the lower side of the pivot pin 3 and the links 29 from the other shark rod 26 are connected to points 30 on the upper side of the pivot pins 3, the rotating moments are balanced , without stressing the bearing of the pivot pins. A snot-corresponding balancing of the moments can of course also be achieved in the other embodiments described by arranging four leveling devices symmetrically in relation to the pivot pins.
Fig. 7 visar ett utforande, yid vilket ramarna 32 aro. anordnade i tvarriktningen mot fordonskroppens 1 langdriktning, och ramarnas 32 svangtappar 3 hava sin gemensamma vridningsaxellinje sammanfallande med cordonskroppens langdaxel. Likso.m enligt fig. 1 Over-roves drivkraften frail motoraggregatet 35 till Iva med styrbromsar 37 fOrsedda styrkopplingar 38 .och fran den ena av dessa genom en kedjevaxel 39 till den centrala axeln 40, sons genom koniska kuggvaxlar 41 driver drivhjulen 4 pa fordonets ena sida, under det att drivkraften frail den andra styrkopplingen 38 genom kedjevaxlar 42 ov.erfores till tvenne rorformade axlar 43 och fran dessa genom koniska kuggvaxlar 44 till drivhjulen 4 pa fordonets andra sida. Utjamningsanordningen visas i detta fall besta av ett biijligt organ 45, exempelvis en kedja, som Riper Over kedjehjul: 46 pa ramarnas 32 svangtappar 3 och Over i fordonskroppen lagrade ledhjul 47. Denna utjamningsanordning verkar naturligtvis pa samma salt som den, sons ovan beskrivits i samband med fig. 5. Fig. 7 shows an embodiment, in which the frames 32 are. arranged in the transverse direction to the longitudinal direction of the vehicle body 1, and the pivot pins 3 of the frames 32 have their common axis of rotation coinciding with the long axis of the cordon body. Similarly, according to Fig. 1, the driving force from the motor assembly 35 to Iva with steering brakes 37 is provided with steering clutches 38, and from one of them through a chain shaft 39 to the central shaft 40, which through conical gears 41 drives the drive wheels 4 on one of the vehicle side, while the driving force from the second steering clutch 38 is transmitted through chain shafts 42 to two tubular shafts 43 and from these through conical gears 44 to the drive wheels 4 on the other side of the vehicle. The leveling device in this case is shown to consist of a flexible member 45, for example a chain, which Riper Over sprockets: 46 on the pivots 3 of the frames 32 and Over guide wheels 47 stored in the vehicle body. This leveling device of course acts on the same salt as the one described above in connection with Fig. 5.
Sasom ovan namnts, kunna utjamningsanordningarna goras installbara, .och de kunna ocksa samtidigt vara fjadrande. Vid de utforingsformer, namligen enligt fig. 5 och 7, yid vilka utjamningsanordningen bestar av Over ledhjul lopande kedjor .eller .andra bojliga organ, kunna ledhjulen jamte fjaderanordningarna fOr dessa, ons sadana a.nvandas, .anordnas i en ram eller dylikt, sons Or installbar i forhallande till fordonskroppen, .exempelvis periferiellt i fOrhallande till de vrid- eller svangtappar, med vilka de bojliga organen Oro forbundna. Nar utjamningsanordningen be-star av havstanger, sasom enligt fig. 6, kunna dessas mittre svangpunkter vara .anbragta i en ram eller dylikt, soin Or ph liknande s5tt installbar i forhallande till fordonskroppen. As mentioned above, the leveling devices can be made installable, and they can also be resilient at the same time. In the embodiments, namely according to Figs. 5 and 7, in which the leveling device consists of chains running over articulated wheels or other flexible members, the articulated wheels and the spring devices for these, which are thus used, can be arranged in a frame or the like, son. Can be installed in relation to the vehicle body, for example peripherally in relation to the pivot or pivot pins with which the flexible members are connected. When the leveling device consists of sea rods, as according to Fig. 6, their central pivot points can be arranged in a frame or the like, soin Or ph similarly installable in relation to the vehicle body.
