Fig 3 visar ett Inidjestyrt bardfordon med tiltade vagnsdelar.Fig. 3 shows an India-controlled bar vehicle with tilted carriage parts.

Fig 4. visar Imrvradie och vridningsceiitrmn för fordonet enligt fig 3., Fig 5 visarkmirvradie och vridningsoentrmn för fordonet enligt fig Bmed låsta irmerbam på fordonet. - ' ' Eig 6 visar scm exempel en starkt förenklad priijicipsldss på bandfordon med anord- g ning enligt uppfinningen. 7 g Fig 7 visar till skillnad från fig 6 fordonet med tiltade vagnsdelar för att, Q _ enligt uppfinningen, kunna erna snäva kurvradier vid körning. rig 1 visar ett ndajestyrt bandfarden, generellt beteekaat 1o, av keramik- tien, där framvagnen betecknas 11 och bakvagnen 12. vid raridryekerr 13,114 jämnt fördeiade under framvagn 11 respdbaiefgaga 12. _ i i rig 2 visar den kurvradie rl sam erhanes i förnånarde ti11 ett vridairgseeaedn 15 när fordonet io enligt fig 1 stan svänga. Nämnda :airvradie r , e11er sem den även sqfrradie, blir relativt» stor een bestäms av vertikala utsiagsvin- keln NI", se fig l, mellan framvagn ll och balzvagri 12.Fig. 4 shows the radius of rotation and rotation of the vehicle for the vehicle according to Fig. 3. Fig. 5 shows the radius of rotation and rotation of the vehicle of the vehicle according to Fig. B with locked armrests on the vehicle. Example 6 shows, for example, a greatly simplified principle of tracked vehicles with devices according to the invention. Fig. 7 shows, in contrast to Fig. 6, the vehicle with tilted carriage parts in order, according to the invention, to be able to narrow radii of curvature when driving. Rig 1 shows a ndaj-controlled belt travel, generally beteekaat 10, of the ceramics, where the front carriage is denoted 11 and the rear carriage 12. at raridryekerr 13,114 evenly distributed under carriage 11 respdbaiefgaga 12. _ ii rig 2 shows the curve radi When the vehicle io according to fig. Mentioned: airvradie r, e11er as it also sqfrradie, becomes relatively "large one is determined by the vertical angle of view NI", see Fig. 1, between front carriage ll and balzvagri 12.

Fig 3 och 4 visar att cm en arrangeras mellan framvagn ll och bakvagn 12, varigenan den inbördes vinkeln i vertikalplanet mellan vagnarna ändras till vimeia M2, kan tyrgdpumden för framvagriens _11 iarvrard 16 een 17 den 1i- . kasåïtyrigdpiimtea för barvagneas 12 1arvbard 18 aan 19 förskjutas. sam denna av vinkeln från _1011 till Oíz, dvs en av vagnarna ll, 12, åstad- 'kunnes en förskjutninglav marktrycken och får utseende enligt beteckningarna 20 och' 21 för framvagn ll resp bakvagn 12 och trycken blir härvid koncentrerade :rot avgfordonet 10. Detta möjliggör, scm fig 47 visar, att en mindre kurvradie. (sízyrradie) rz kan erhållas i förhållande till vridningscenmm 15 när fordonet i 1o sken svänga. rig s' visar att ytteriigare reducering av kurvradien (styrradien) ti11 ett värde r3 kan erhållas cm fordonet 10 enligt fig 3 köras ned låsta innerband 16 och l8 och där ytterbaruden 17 och 19 får driva fordonet 10 runt. Det är härvid Inöjligt att erhålla den styrradie ra som endast obetydligt överskrider fordonets 10 halva längd. ' Fig 6 och 7 visar hur fordonet, nu betecknat 10' , försetts med en förskjutnings- ainrdaiirgd ' dlzzkned vilken inbördes vertikala vinkeln kan ändras från v41 till az 2 (se fig l och 3) mellan framwmgn ll och bakvagn 12, dvs en tiltniixg mellan vag- narna, ll V12 kan åstadkommas. I det visade¿utföri.rigsexerplet utgöres förskjut- -ß- _ 7aos7s4-1 ningsarnrdxaingen av en hydraulisk cylinder 22 vars ena sida, via en horisontell áxei 23, ett ieaetyeke 24, en vertikal axel 25 och ett fäste 26, är kopplad tm bexçvegnefe 12 frame karoesíaa 27. nyarauieynmerns 22 andra eiaa, avs hydraul- cylinderns kolvstårg 28, är via en horisontell axel 23, ett ledstycke 24, en ver- tikal axel- 25 och ett fäste 26 kopplad till frarnvagrxens ll_bakre karossida 29.Figs. 3 and 4 show that cm one is arranged between front carriage 11 and rear carriage 12, whereby the mutual angle in the vertical plane between the carriages is changed to vimeia M2, the turbulence pump for the front carriage 11 may 16 16 and 17 on 1i. kasåïtyrigdpiimtea for barvagneas 12 1arvbard 18 aan 19 displaced. At the same time from the angle from 1011 to Oiz, i.e. one of the carriages 11, 12, a displacement of the ground pressures could be effected and appears according to the designations 20 and 21 for front carriage 11 and rear carriage 12, respectively, and the pressures are concentrated in this case: the root vehicle 10. This enables, as Fig. 47 shows, that a smaller radius of curvature. (sieve radius) rz can be obtained in relation to the rotational scene 15 when the vehicle is turning in a light. rig s' shows that further reduction of the curve radius (steering radius) to a value r3 can be obtained if the vehicle 10 according to Fig. 3 is driven down locked inner bands 16 and 18 and where the outer windows 17 and 19 are allowed to drive the vehicle 10 around. In this case, it is impossible to obtain the steering radius which only slightly exceeds the length of the vehicle 10. Figs. 6 and 7 show how the vehicle, now designated 10 ', is provided with a displacement device which is mutually vertical angle can be changed from v41 to az 2 (see Figs. 1 and 3) between the front end 11 and the rear carriage 12, i.e. a tilt between the carriages, ll V12 can be achieved. In the embodiment shown, the displacement is constituted by the displacement of a hydraulic cylinder 22, one side of which, via a horizontal axis 23, a plane 24, a vertical axis 25 and a bracket 26, is connected to the motor shaft. 12 frame karoesíaa 27. The second eiaa of the nyarauieynmer 22, of the piston frame 28 of the hydraulic cylinder, is connected via a horizontal shaft 23, a joint 24, a vertical shaft 25 and a bracket 26 to the rear body side 29 of the front axle 11.

Mellan framvagn ll och bakvagn 12 finns en normal kopplingsamrdnizmg, generellt bei-.ecknad 30, bestâerxie i princip av två koælixxgsanmr 31 resp 32, en vertikal axel 33 och två horisontella axlar 34, vilka enheter är kopplade mellan framvag- nens ll bakre karossida 29 och bakvagnerzs 12 främre karossida 27. å Genau att ansluta hydraulcylizadern 22 till ett fordonet 10' tillhörande oljeför- sörjningssystan (ej visat) kan önskad tilmixxg mellan framvagn ll och bakvagn 12 erhållas, se fig 7, och därigenun kan fordonet 10' framföras med snäv loirvradie rz eller r3, se fig 4 resp 5, beroende på cm inre larvbanden l6 och 18 under kör- ningen är låsta eller ej.Between the front carriage 11 and the rear carriage 12 there is a normal coupling arrangement, generally designated 30, consisting in principle of two coil axle numbers 31 and 32, a vertical shaft 33 and two horizontal axles 34, which units are connected between the rear body side 29 of the front carriage 11 and the front body side 27 of the rear trailer 12. Exactly to connect the hydraulic cylinder 22 to an oil supply system belonging to the vehicle 10 '(not shown), the desired mixture between the front trailer 11 and the rear trailer 12 can be obtained, see Fig. 7, and thereby the vehicle 10' can be driven narrowly. loirvvdie rz or r3, see fig. 4 and 5 respectively, depending on whether the inner caterpillar tracks l6 and 18 during driving are locked or not.

Figurerna visar inte detïnomela laaftförsörjningssystaxxet för fordonet 10' men sådant systen ingår givetvis och är av känd typ, lilcaså lcraftöverföriiagen mellan franvagn ll och bakvagn 12. ' Givetvis är uppfinningen ej begränsad till beskrivna utförixgsfonn utan kan till- lärrpas på alla xrcldjestyrda fordon, således ej enbart banclfordonutan även hjul- föreeaae fordon. ' 'The figures do not show the current supply system for the vehicle 10 ', but such a system is of course included and is of known type, as the power transfer between carriage 11 and rear carriage 12. Of course, the invention is not limited to described embodiments but can be taught on all vehicles, thus not only bancl vehicles without also wheeled vehicles. ''
