KrAz-257: iimpawu awohluke

Kremenchug Automobile Plant (Ukraine) yasekwa ngowe-1945 kwaye iye Ningazenzi into enye kuphela enzima inkokheli Ushishino lweemoto, kodwa azisebenzisele enamandla imvuselelo noqoqosho zeli lizwe emva kweMfazwe Yehlabathi II.

ummeli edume

Enye imodeli kakhulu nempumelelo yaba ilori KrAZ-257. Lakhutshwa ukususela ngowe-1965 ukuya 1977 (ukuguqulwa 257B1 - to 1995), kwaye isasetyenziswa nangoku namhlanje. ithandwa kangaka kuqinisekiswa kuphela ngcono xa kuthelekiswa uguqulelo yangaphambili, iimpawu, kodwa ukuhlanganiswa ekhethekileyo kukuthembeka, permeability, umbane. Yiloo nto le modeli kubizwa ngokuba kaHomer. KrAZ-257 kunye noqwalaselo yayo ezisetyenziswa omabini emkhosini yaye imali yoluntu, kokubini apha ezidolophini kunye nezicwangciso yasemaphandleni.

Equipment KrAZ-257

Ukucacisa lo mzekelo, cishe kubangelwa bazimisela umfanekiso ilori enzima mihla:

1. yenjini. Ngelori kokuba ifakelwe ezimilise V-phambili,-umjikelo ezine, OHV idizili YaMZ 238 M2. Waye umthamo ezahlukeneyo, ubuchule, ukuthembeka: 240 hp ngesantya seelitha ezili-36 100 km. injini truck yafakwa kunye ukususa uthuli, imodeli entsha ye muffler kunye injini wayaphula. Konke oku kuye kwenza zithembeke ngakumbi, ukuba sandise ubomi nkonzo.

2. Transmission, iklatshi, ivili lokuqhuba. A Kwabekwa manual ngesantya ezintlanu-manual, 5 isantya-overdrive kwam. Kokubonisa kunye ezibini kunye bomile, kwaye esungulayo indlela - 2-sigaba booster longeziweyo. Ezi mpawu ukuqinisekisa kuphela isantya elungileyo kunye abagqibayo, kodwa controllability eliphezulu xa kuthelekiswa neyezingaphambili.

3. Izixhobo. KrAz-257 yafakwa nge elektroniki zaphambili ixesha: inkqubo wire enye (24), iibhetri ababini, omnye ubukhulu zibencinane kwaye ukuyithwala imifuziselo lwangaphambili.

ezineenkcukacha ze KrAZ-257

1. umthamo permeability. Ngenxa enjinini ekhethekileyo KrAz-257 wayekho phakathi titanium owayephila: umthamo walo iitoni ezili-12 (ukunyuka - 10%). Ngaphezu koko, le lori omtsha uyakwazi ukuthutha ezirhuqwayo ezinobunzima iyonke ubuninzi iitoni ezingama 16.5 kwenjini 257 yanika imodeli yokuqala ibonwe cross-lizwe unyuko. 18%. Loo Uphawu ayifumaneki kwaye uluhlu iilori enzima mihla. Ukongeza, ibhasi ngokubanzi kunye hlengiso uxinzelelo lomoya esembindini nokuphuculwa nokumiswa angasemva wajika truck okunene lihamba. Yena lula basebenza iindlela zegrabile yaye uvakalelo kuyehla nezitenxo.

2. Speed. Ukongeza amandla, KrAz-257 has a eliphezulu isantya ukuya ku-62 km / h kwi iinguqulelo eziphambili 76 yaye - xa kwimeko crane elorini. La manani zabonelelwa njenge injini enamandla kunye nokunyusa inani revolutions le crankshaft.

3. ukuthembeka. ezintsha Design isicelo kwi KrAZ-257, zazijoliswe kwi ukuqinisekisa ukusebenza layo eliphezulu, ukuthembeka kunye nokuqina xa zisebenza phantsi kweemeko ezahlukeneyo: esixekweni ezilalini, kwi efudumeleyo engontsini yasentla. Njengoko kucwangciswe liSebe abayili, le lori akazange mfuneko igaraji.

ukululama

Ngokwesiseko imodeli kanye milenge zayo uguqulelo zaveliswa, ezo nani nangoku ukusebenza kwaye isetyenziswe ngempumelelo mveliso eyahlukeneyo. Kwi crane isisu semoto 257 imodeli th efakiweyo KS-4561A. Le ukuguqulwa lasebenza ngempumelelo kulwakhiwo, ezolimo, kunye nomkhosi, ingakumbi amajoni enomjukujelwa (ekukhuliseni iimbumbulu live). Uninzi iimpawu zobugcisa kwendwe aba efanayo kwinguqulelo esisiseko (evenini). Umahluko ophambili yaba isantya - ukuya ku-76 km / h kuthelekiswa 62 km / h kule lori. Crane KrAz-257 iye mayixhotyiswe esitsholo m-10 ubude. Xa ubude iinguqulelo baso 14, 18 okanye 22 eemitha. Ubude jib -. 5 m Ubunzima iphezulu umthwalo waphakamisa nga okulahlwayo ukuya ku-16, nayo efakwe kwi-crane drive kwaye generator ESS5-82-4U2 ..
