Independent work prepared by Boltayeva Ziyoda, a 3rd-year student of Fergana Polytechnic Institute, Faculty of Mechanics and Mechanical Engineering, on the topic "Longitudinal cars in normal stagnation"

 Oʻt oʻchirish, un tashish, sement tashish, sanitariya avtomobillari, axlat tashiydigan avtomobillar, avtokranlar, avtoyuklagichlar va boshqa maxsus avtomobillar shular jumlasidan. Poyga avtomobillari sportda ishla-tiladi. Yengil avtomobillar 2 dan 8 tagacha oʻrinli boʻladi. Ular berk kuzovli (sedan va limuzin), ochiq kuzovli (faeton) va ochiladigan kuzovli (kabriolet) boʻlishi mumkin. Yuk avtomobillari 0,25 tonnadan 100 tonnagacha va undan ortiq yuklarni tashiydigan kuzovli, tirkamalar, yarim tirkamalarni tortish uchun muljallangan kuzovsiz boʻladi. Oʻtuvchanligi boʻyicha tekis va qiyin yoʻllarda yuradigan, harakatlanuvchi qismning tuzilishi boʻyicha gʻildirakli, gʻildirak-gusenitsali, yarim gusenitsali, pnevmatik galtakli va boshqa xillarga boʻlinadi.

Stagnation of the car Stagnation is the movement, sliding, overturning of the car. the characteristics of resistance are understood. Of the car there will be longitudinal and transverse stagnation. Longitudinal stability- loss of is very rare in cars, it is very sharp can be done on slopes. Therefore, when it comes to car stagnation, it is usually its transverse stability is assumed. Stagnation of the car evaluated by several indicators. The main one is: circle causing the car to push and (overturn) when moving the greatest possible speed; cause the wheel to be pushed sideways the largest angle of inclination; overturning of the car the largest slope angle corresponding to the start. ________________________________________ 45 In many cases, traffic congestion on the road from the height of its center of gravity, base, wheels, tires size, construction, condition, radius of curvature of the road and its the condition of the surface depends on the speed of movement.

Sirpanchiq yo‘llarda ag‘darilishdan ko‘ra, uning surilishi yoki sirpanishi ko‘proq sodir bo‘ladi. Tishlanish sifatlari yaxshi bo‘lgan yo‘llarda ag‘darilish holatlari ko‘proq bo‘lishi mumkin. Og‘irlik markazi yuqori bo‘lganligi uchun yengil avtomobillardan ko‘ra, yuk avtomobillarining turg‘unligi kamroq bo‘ladi. Yuk avtomobillari yuklangan sari ularning og‘irlik markazi balandga ko‘tarilib, turg‘unligi yomonlashadi. Yuk avtomobili turg‘unligining yo‘qolishiga mahkamlanmagan yuklar ham sabab bo‘lishi mumkin. Burilishlarda mahkamlanmagan yuk yukxonadan siljib, devorga urilib, avtomobilning ag‘darilishiga olib kelishi mumkin. Avtomobil sisternalari yoki o‘zi ag‘daruvchi avtomobil suyuq (masalan, suyuq qorishma) yuklarni tashiganda ham shunday bo‘lishi mumkin. Egrilik bo‘ylab harakatlanganda suyuqlik tashuvchi avtomobillarning yuki bir devordan ikkinchisiga siljib, chayqalib turadi va u avtomobil turg‘unligining yo‘qolishiga olib keladi.
