KrAz-257: unhu uye peculiarities

Kremenchug Automobile Plant (Ukraine) yakavambwa muna 1945 uye ava kwete chete mumwe inorema motokari mutungamiri maindasitiri, asiwo simba mhikuriso nokuda nyika zvoupfumi kumutsidzirwa pashure peHondo Yenyika II.

kunozivikanwa mumiririri

Imwe inobudirira zvikuru muenzaniso raiva rori KrAZ-257. Yakanga yakagadzirwa 1965 1977 (nadzurudzo 257B1 - kusvika 1995), uye richiri kushandiswa nanhasi. kukurumbira kwakadaro kunosimbiswa kwete chete hwakavandudzika kuenzaniswa yapfuura shanduro, zvainyanya, asiwo yakasiyana mubatanidzwa rakavimbika, permeability, akatakura chinzvimbo. Ndicho muenzaniso uyu anonzi kunozivikanwa. KrAZ-257 uye ayo okunatsiridza zvinonzi nevakawanda kushandiswa zvese muhondo uye vehurumende turnover, zvose mumaguta uye mumaruwa kurongwa.

Equipment KrAZ-257

Magadzirirwo akaitwa uyu wokuenzanisira kunozivikanwa, zvinonyanya vakatsunga mufananidzo ano inorema rori:

1. Engine. On murori nayo paakagadzwa yemhando V-zvakaumbwa, zvina-kutenderera, OHV Diesel YaMZ 238 M2. Akanga akasiyana chinzvimbo, kushanda zvakanaka, kuvimbika: 240 zvapano pamwero wenyika marita 36 paminiti 100 km. marori Injini akanga nepokuongorora guruva dzokubudisa, muenzaniso itsva mafuro uye injini akaputsa. izvi zvose akaita izvozvo zvikuru chakavimbika, akabvumira kuwedzera upenyu basa.

2. Transmission, batira, gozvo. A rori wakaiswa Chinyorwa shanu-nokukurumidza manual, 5-nokukurumidza overdrive Ndaiva. Payakabatanidzwa pamwe Dual uye rakanga rakaoma, uye gozvo mashandiro - 2-Danho vaisanganisa booster. Izvi zvinhu kwete chete nechokwadi nokukurumidza zvakanaka uye throughput, asiwo yakakwirira controllability zvichienzaniswa ayo vamutangira.

3. Equipment. KrAz-257 akanga vakapakata yepamusoro zvemagetsi kwenguva: kuroorwa waya hurongwa (24), mabhatiri maviri, mumwe saizi duku uye uremu pane yapfuura yokutevedzera.

Detailed nokurondedzerwa pamusoro KrAZ-257

1. kugona uye permeability. Nokuda rinokosha injini KrAz-257 akanga aripo pakati panguva titanium: pakukwanisa kwayo kwakanga matani 12 (kuwedzera - 10%). Uyezve, rori itsva anokwanisa kutakura Trailers ane zvachose kunonyanyisa uremu matani 16.5 Engine 257 akapa muenzaniso isati yamboitwa muchinjikwa nyika yokutanga kuwedzera. 18%. mamirire akadaro haasi kuwanika uye zvakawanda ano inorema mumarori. Uyezve, rakapamhamha bhazi pamwe centralized mhepo kufurirwa kuchinja uye akavandudzika neshure kuturika akatendeuka rori chaizvoizvo gororo. Iye nyore aishanda ari tsvina mumigwagwa uye aiva kuderedzwa aikanganiswa hadzina kufambiswa zvakanaka.

2. Speed. Kuwedzera simba, KrAz-257 ane hwakanyatsorwisa kumhanya kusvika 62 km / h mu huru okunatsiridza kusvika 76 uye - pakuparwa rori kondo. Izvi nhamba zvakagoverwa ari injini simba uye vakawedzera uwandu nokumukirana yacho crankshaft.

3. Kuvimbika. Design zvakagadzirwa rakaiswa mune KrAZ-257, vakanga zvainanga kuti rive nechokwadi chekuenderera kunonyanyisa kunyatsoshanda, akavimbika uye mukurumari kana uchishanda ezvinhu akasiyana: muguta uye mumusha, muna subtropics uye ari kure kuchamhembe. Sezvo aronga nokuda vagadziri, rori haana kuva garaji.

kupora

Pahwaro muenzaniso uye ayo okunatsiridza yakabereka Cranes, iyo vari vachiri kushanda uye vave vakabudirira kushandiswa maindasitiri akasiyana-siyana. On the chassis 257 fung womuenzaniso akagadzawo Crane KS-4561A. nadzurudzo iyi zvinobudirira kushandiswa pakuvaka, zvokurima, uyewo muhondo, kunyanya chombo mauto (kumutsa mhenyu zvombo). Vazhinji michina zvechadenga Crane vaiva zvakafanana mune inokosha version (mumotokari). The musiyano mukuru waiva nokukurumidza - kusvika 76 km / h zvichienzaniswa 62 km / h murori. Crane KrAz-257 akanga nepokuongorora tiguu mamita 10 refu. In okunatsiridza kureba kwakanga 14, 18 kana 22 mamita. Kureba jib -. 5 m The kunonyanyisa kurema kusimudzwa mutoro zvinogona kusvika 16 matani, ari akagadzawo pamusoro Crane nemotokari uye jenareta ESS5-82-4U2 ..
