Ithangi lempi elikhulu Uhlobo 74
I-tank main "74" inesakhiwo sakudala esinenjini eqinile kanye nokudluliselwa. I-hull yayo ihlanganiswe kusuka kumapuleti ezikhali, i-turret iphonswa. Ukuvikelwa kwe-Ballistic kwenziwa ngcono ngokusetshenziswa kwe-turret ehlelekile kanye nama-engeli aphezulu okuthambekela kwamapuleti ezikhali angaphezulu e-hull. Ubukhulu obukhulu bezikhali zengxenye engaphambili yesikebhe ngu-110 mm e-engeli yokuthambekela engu-65 °. Isibhamu esikhulu sethangi isibhamu sesiNgisi esingu-105 mm L7A1, esizinze ezindizeni ezimbili eziqondisayo. Ikhiqizwa ngaphansi kwelayisensi nguNippon Seikose. Imishini yokubuyisela kabusha ithuthukisiwe. Ingadubula izinhlamvu ezingu-105-mm ezisetshenziswa emabuthweni amazwe e-NATO, okuhlanganisa ne-American arm-piercing M735 sub-caliber projectile, ekhiqizwa e-Japan ngaphansi kwelayisensi.
Umthwalo wezinhlamvu wethangi elithi "74" uhlanganisa kuphela izinga eliphansi lokubhoboza izikhali kanye namagobolondo aqhuma phezulu, isamba semizuliswano engama-55, abekwe endaweni engemuva yombhoshongo. Ukulayisha mathupha. Isibhamu esiqondile sikhomba ama-engeli ukusuka ku -6° ukuya +9°. Ngenxa yokumiswa kwe-hydropneumatic, zingandiswa futhi zisukela ku--12 ° ziye ku-15 °. Izikhali ezisizayo zethangi "74" zihlanganisa isibhamu somshini we-coaxial esingu-7,62 mm esitholakala kwesokunxele se-cannon (izinhlamvu ezingu-4500 zezinhlamvu). Isibhamu somshini esilwa nendiza esingu-12,7-mm sibekwe obala kubakaki ku-turret phakathi kwama-hatches omlawuli kanye nesilayishi. Ingaxoshwa yibo bobabili umlayishi kanye nomlawuli. Ama-engeli aqondile wokukhomba esibhamu somshini akubanga ukusuka ku--10° ukuya ku-+60°. Izinhlamvu - 660 imizuliswano.
Ezinhlangothini zengxenye engemuva kombhoshongo, iziqhumane ezintathu zamabhomu zifakwe ukuze kumiswe izikrini zentuthu. Uhlelo lokulawula umlilo luhlanganisa i-laser sight-rangefinder, izinto ezibonwayo eziyinhloko nezingeziwe zomdubuli, i-weapon stabilizer, i-electronic ballistic computer, amaphaneli okulawula omkhuzi kanye nesibhamu, kanye neziqondiso zokulinganisa ububanzi nokulungiselela idatha ukudubula kunikezwa umkhuzi. Usebenzisa i-periscopic sight ehlanganisiwe (imini/ebusuku), ene-ruby laser rangefinder eyakhelwe ngaphakathi ekala ibanga ukusuka ku-300 kuya ku-4000 m. Umbono unokukhulisa okungu-8x futhi uxhunywe kunganono usebenzisa idivayisi yepharalelogramu. Ukuze kubonakale yonke indawo, kukhona amadivaysi okubuka ama-periscopic amahlanu afakwe eduze kwe-perimeter ye-hatch yomyali. Isishayasibhamu sinokubona okuyinhloko okuhlanganisiwe (imini/ebusuku) kwe-periscope ene-8x magnification kanye nombono osizayo we-telescopic, amadivayisi okubona ebusuku ohlobo olusebenzayo. Okuqondiwe kukhanyiswa isibani se-xenon esifakwe kwesokunxele semaski yesibhamu.
Kufakwe ikhompuyutha yedijithali ye-electronic ballistic phakathi komkhuzi nomdubuli, ngosizo lwazo, ngokusebenzisa izinzwa zolwazi olufakiwe (uhlobo lwezinhlamvu, izinga lokushisa eliyimpushana, ukuguga komphongolo, i-pivot axis tilt angle, isivinini somoya), ukulungisa isibhamu. ama-engeli ahlosiwe angeniswa endaweni yomphathi kanye nesibhamu. Idatha ebangeni eliqondiswe ku-laser rangefinder ifakwa kukhompuyutha ngokuzenzakalelayo. I-stabilizer yezikhali ezimbili inamadrayivu e-electromechanical. Ukukhomba nokudubula kusuka kunganono kanye nesibhamu somshini we-coaxial kungenziwa yibo bobabili umdubuli kanye nomkhuzi besebenzisa amaphaneli okulawula afanayo. Isidubuli, ngaphezu kwalokho, sifakwe amadrayivu esandla ayimpinda yokuphokophela okuqondile nokujikeleza kwe-turret.
Isilayishi sinedivayisi yokubuka ye-periscope ejikelezayo engu-360 ° efakwe ngaphambi kwe-hatch yayo. Umshayeli utholakala endaweni yokulawula engxenyeni engaphambili kwesokunxele yesikebhe. Inamadivayisi amathathu okubuka i-periscopic. Ochwepheshe baseJapane banaka kakhulu ekwandiseni ukuhamba kwethangi, njengoba ezindaweni eziningi zaseJapane kunezindawo okunzima ukudlula kuzo (amasimu erayisi anodaka, izintaba, njll.). Imigwaqo yamazwe mincane, amabhuloho kuwo umthamo ophansi wokuthwala. Konke lokhu unciphise ubukhulu bethangi, okungamathani angu-38. I-tank ine-silhouette ephansi kakhulu - ubude bayo buyi-2,25 m kuphela. Lokhu kwafezwa ngokusebenzisa ukumiswa kohlobo lwe-hydropneumatic, okuvumela ukuthi ushintshe imvume yomhlabathi yemoto kusuka ku-200 mm kuya ku-650 mm. , kanye nokutshekisa ithangi ebhodini kwesokudla noma kwesokunxele kokubili ngokuphelele futhi ingxenye, kuye ngokuthi isimo sezwe.
Ukuthambekela komshini kunikezwa ngokulungisa amayunithi amane okumiswa kwe-hydropneumatic atholakala kumasondo omgwaqo wokuqala nowesihlanu ohlangothini ngalunye. Inqola yangaphansi ayinawo amarola asekelayo. Ukuhamba okuphelele kwe-roller yethrekhi ngu-450 mm. Ukungezwani kwezibungu kungenziwa ngumshayeli endaweni yakhe ngosizo lwe-hydraulic drive ye-tensioning mechanism. Ithangi lisebenzisa izinhlobo ezimbili zamathrekhi (ububanzi obungu-550 mm) anehinji yerabha-yensimbi: amathrekhi okuqeqesha anamathrekhi enjoloba futhi alwe namathrekhi ensimbi yonke anamalugi aqinisiwe. Injini kanye nokuhanjiswa kwethangi kwenziwa kubhulokhi eyodwa.
Injini yedizili eyi-10 10P 2 WТ enama-stroke amabili emise okwe-V eyi-22 yasetshenziswa njengesikhungo samandla. Ifakwe ama-turbocharger amabili axhunywe ngamagiya ku-crankshaft. Idrayivu ye-compressor ihlanganisiwe (imishini evela enjini futhi isebenzisa amagesi okukhipha umoya). Lokhu kuthuthukisa kakhulu ukusabela kwe-throttle yenjini enama-stroke amabili. Abalandeli ababili be-axial besistimu yokupholisa batholakala ngokuvundlile phakathi kwamabhulokhi angama-cylinder. Ngejubane eliphezulu (2200 rpm), 120 hp kudliwe ukushayela bobabili abalandeli. sec., eyehlisa amandla enjini ukusuka ku-870 kuya ku-750 amalitha. nge. Injini eyomile isisindo 2200 kg. Ngaphezu kophethiloli ojwayelekile wedizili, ingasebenza ngophethroli kanye nophalafini wendiza.
Ibanga lika-140km isebenzisa amalitha angu-100. I-MT75A hydromechanical transmission yohlobo lwe-Mitsubishi Cross-Drive inikeza amagiya ayisithupha aya phambili kanye negiya elilodwa elibuyela emuva ngaphandle kokucindezela i-clutch pedal, esetshenziswa kuphela lapho uqala futhi umisa ithangi. I-Tank "74" ifakwe uhlelo lokuvikela ngokumelene nezikhali zokubhujiswa okukhulu. Ingakwazi ukunqoba izithiyo zamanzi kuze kufike ku-4 m ukujula ngosizo lwemishini yokushayela ngaphansi kwamanzi. Ukukhiqizwa kwamathangi ohlobo lwama-74 kwaphela ekupheleni kuka-1988. Ngaleso sikhathi, amasosha aphansi athola izimoto ezinjalo ezingu-873. Ngokwesisekelo sethangi elithi "74", uhlobo 155 lwe-howitzer oluzihambelayo oluyi-75 mm (ngaphandle lufana ne-American M109 howitzer), ungqimba lwebhuloho kanye nemoto yokulungisa izikhali nokubuyisela uhlobo 78, izici zayo ezihambisana nesiJalimane. I-BREM ejwayelekile, yadalwa. Tank Type 74 kwamanye amazwe akuhlinzekwanga kanye nokubamba iqhaza ezimpini hhayi kwamukelwe.

Ngo-1962, iMitsubishi Heavy Industries yaqala ukwakha ithangi lempi elikhulu. Izidingo ezilandelayo zabekwa phambi kwabadali bethangi elisha: ukwandisa amandla omlilo, ukwandisa ukuphepha nokuhamba kwalo. Ngemva kweminyaka eyisikhombisa yomsebenzi, inkampani yakha ama-prototypes amabili okuqala, athola igama elithi 8TV-1. Bahlola izixazululo ezinjengokulayisha isibhamu ngomshini, ukufakwa kwenjini eyisiza, ukulawula isibhamu somshini ovikela indiza esisuka ngaphakathi ethangini, nokuzinzisa izikhali. Ngaleso sikhathi, lezi zazinesibindi futhi zingavamile ukubonakala ezinqumweni zokusebenza. Ngeshwa, ezinye zazo kwadingeka zishiywe ngesikhathi sokukhiqiza ngobuningi. Ngo-1971, i-prototype 8TV-3 yakhiwa, lapho kwakungekho uhlelo lokulayisha isibhamu ngomshini. I-prototype yokugcina, eqokwe i-8TV-6, yethulwa ngo-1973. Ngesikhathi esifanayo, kwanqunywa ukuba kuqalwe ukukhiqizwa ngobuningi bomshini omusha, ekugcineni owaziwa ngokuthi Uhlobo 74.
