Xyoo 1935, kev hloov kho tshiab ntawm BT tso tsheb hlau luam, uas tau txais qhov ntsuas BT-7, tau muab tso rau hauv kev pabcuam thiab muab tso rau hauv ntau lawm. Lub tank tau tsim kom txog thaum xyoo 1940 thiab tau hloov los ntawm T-34 tank. (Tseem nyeem "Tsev Tank T-44") Piv nrog rau BT-5 lub tank, nws cov qauv tsim tau hloov pauv, kev tiv thaiv armor tau raug txhim kho, thiab lub cav txhim khu kev qha tau raug teeb tsa. Ib feem ntawm kev sib txuas ntawm daim hlau armor ntawm lub hull twb tau ua los ntawm vuam.
Cov nram qab no variants ntawm lub tank tau tsim:
- BT-7 - linear tank tsis muaj xov tooj cua; txij li xyoo 1937 nws tau tsim nrog lub conical turret;
- BT-7RT - hais kom ua tank nrog xov tooj cua chaw nres tsheb 71-TK-1 lossis 71-TK-Z; txij li xyoo 1938 nws tau tsim nrog lub conical turret;
Nyob rau hauv tag nrho, ntau tshaj 5700 BT-7 tanks tau tsim. Lawv tau siv thaum lub sijhawm kev ywj pheej hauv Western Ukraine thiab Belarus, thaum ua tsov rog nrog Finland thiab hauv Great Patriotic War.
Lub tank BT-7.
Tsim thiab modernization
Xyoo 1935, KhPZ tau pib tsim cov kev hloov pauv tom ntej ntawm lub tank, BT-7. Qhov kev hloov kho no tau txhim kho kev muaj peev xwm hla teb chaws, nce kev ntseeg siab thiab ua kom yooj yim rau kev ua haujlwm. Tsis tas li ntawd, BT-7 featured armor thicker.
Lub BT-7 tso tsheb hlau luam tau rov tsim dua tshiab, nrog lub ntim loj, thiab cov cuab yeej hnyav dua. Vuam tau dav siv los txuas cov cuab yeej armor. Lub tank tau nruab nrog lub cav M-17 ntawm lub zog tsawg thiab nrog lub tshuab hluav taws xob hloov pauv. Lub peev xwm ntawm cov roj tank tau nce. BT-7 muaj ib tug tshiab lub ntsiab clutch thiab gearbox, tsim los ntawm A. Morozov. Sab clutches siv cov sib txawv ntab brakes tsim los ntawm xibfwb V. Zaslavsky. Rau qhov zoo ntawm KhPZ nyob rau hauv lub tshav pob lub tsev nyob rau hauv 1935, cov nroj tsuag tau muab tsub lub Order ntawm Lenin.
Ntawm BT-7 ntawm thawj qhov teeb meem, nrog rau ntawm BT-5, cylindrical yees tau teeb tsa. Tab sis twb nyob rau hauv 1937, cylindrical yees tau muab txoj hauv kev rau conical tag nrho cov welded sawv daws yuav, tus yam ntxwv los ntawm ib tug zoo dua armor thickness. Nyob rau hauv 1938, lub tso tsheb hlau luam tau txais tshiab telescopic pom nrog ib tug stabilized aiming kab. Tsis tas li ntawd, tso tsheb hlau luam tau pib siv cov kev sib cais-txuas txuas nrog lub suab qis, uas pom lawv tus kheej zoo dua thaum tsav tsheb ceev. Kev siv cov lem tshiab yuav tsum muaj kev hloov pauv hauv kev tsim ntawm lub log tsav.
Qee lub xov tooj cua BT-7s (nrog lub cylindrical turret) tau nruab nrog lub kav hlau txais xov, tab sis BT-7s nrog lub conical turret tau txais lub xov tooj tshiab.
Xyoo 1938, qee cov kab tso tsheb hlau luam (tsis muaj xov tooj cua) tau txais ib rab phom DT ntxiv nyob rau hauv lub turret niche. Nyob rau tib lub sijhawm, cov mos txwv yuav tsum tau txo qis me ntsis. Qee lub tso tsheb hlau luam tau nruab nrog P-40 los tiv thaiv lub dav hlau rab phom, nrog rau ob lub teeb pom kev muaj zog (xws li BT-5) nyob saum lub phom thiab ua haujlwm kom pom lub hom phiaj. Txawm li cas los xij, hauv kev xyaum, cov teeb pom kev zoo li no tsis tau siv, vim nws tau pom tias lawv tsis yooj yim los tswj thiab khiav lag luam. Lub tankers hu ua BT-7 "Betka" lossis "Betushka".
Qhov kawg serial qauv ntawm BT tank yog BT-7M.
Cov kev paub ntawm kev sib ntaus sib tua hauv Spain (nyob rau hauv uas BT-5 tso tsheb hlau luam tau koom nrog) tau qhia tias yuav tsum muaj lub tank siab dua hauv kev pabcuam, thiab nyob rau lub caij nplooj ntoo hlav xyoo 1938, ABTU pib tsim tus neeg ua tiav rau BT - lub log tsheb nrawm. -tracked tank nrog riam phom zoo sib xws, tab sis kev tiv thaiv zoo dua thiab tiv thaiv ntau dua. Yog li ntawd, tus qauv A-20 tau tshwm sim, thiab tom qab ntawd A-30 (txawm tias cov tub rog tau tawm tsam lub tshuab no). Txawm li cas los xij, cov tshuab no feem ntau tsis yog txuas ntxiv ntawm BT kab, tab sis pib ntawm T-34 kab.
Nyob rau tib lub sijhawm nrog kev tsim khoom thiab kev tsim kho tshiab ntawm BT tso tsheb hlau luam, KhPZ pib tsim lub tshuab hluav taws xob muaj zog, uas yav tom ntej yuav tsum tau hloov cov tsis ntseeg siab, capricious thiab hluav taws kub hnyiab carburetor cav M-5 (M-17). Rov qab rau xyoo 1931-1932, NAMI / NATI tsim chaw ua haujlwm hauv Moscow, coj los ntawm xibfwb A.K. Dyachkov, tsim ib qhov project rau D-300 diesel cav (12-lub tog raj kheej, V-shaped, 300 hp), tshwj xeeb tshaj yog tsim rau kev teeb tsa ntawm cov tso tsheb hlau luam. ... Txawm li cas los xij, nws tsuas yog nyob rau xyoo 1935 uas thawj tus qauv ntawm lub tshuab hluav taws xob no tau tsim los ntawm Kirov Cog hauv Leningrad. Nws tau nruab rau ntawm BT-5 thiab sim. Cov txiaj ntsig tau poob siab vim tias lub zog diesel tsis txaus.
Ntawm KhPZ, 400th department coj los ntawm K. Cheplan tau koom nrog kev tsim lub tank diesel xyaw. Lub 400th department tau koom tes nrog lub department ntawm engine VAMM thiab CIAM (Central Institute of Aviation Engines). Xyoo 1933, BD-2 diesel cav tau tshwm sim (12-lub tog raj kheej, V-shaped, tsim 400 hp ntawm 1700 rpm, roj noj 180-190 g / h / h). Thaum lub Kaum Ib Hlis 1935, lub tshuab hluav taws xob tau nruab rau ntawm BT-5 thiab sim.
Thaum lub Peb Hlis Ntuj xyoo 1936, lub tank diesel tau nthuav tawm rau pawg neeg siab tshaj plaws, tsoomfwv thiab tub rog. BD-2 xav tau kev kho kom zoo ntxiv. Txawm li cas los xij, nws twb tau muab tso rau hauv kev pabcuam hauv xyoo 1937, raws li lub npe B-2. Lub sij hawm no, muaj ib tug reorganization ntawm lub 400th department, uas xaus nyob rau hauv lub tsos nyob rau hauv Lub ib hlis ntuj 1939 ntawm lub Kharkov Diesel Building Plant (HDZ), los yog hu ua tsob nroj No. 75. Nws yog KhDZ uas tau dhau los ua cov chaw tsim khoom tseem ceeb ntawm V-2 diesels.
Los ntawm 1935 txog 1940, 5328 BT-7 tso tsheb hlau luam ntawm txhua qhov kev hloov kho (tsis suav BT-7A) tau tsim. Lawv tau ua haujlwm nrog cov tub rog armored thiab mechanized ntawm Red Army rau yuav luag tag nrho cov tsov rog.
