Formula 500
Formula 500 (F500) — bu Amerika sport avtomobillari klubi (SCCA) va Oʻrta gʻarbiy sport avtomobil klublari kengashi (MCSCC) tomonidan tashkil etilgan ochiq gʻildirakli poyga musobaqasi hisoblanadi[1].
Formula 500 dastlab 1980-yillarning boshida Formula 440 (F440) sifatida tashkil etilgan. Bir nechta shassi ishlab chiqaruvchilari yangi qoidalar toʻplamiga turli dizaynlarni ishlab chiqaradilar. Dvigatellar qoidalar toʻplami bilan belgilanadi va ishlab chiqaruvchilarga dvigatelning ichki qismlarini oʻzgartirishga ruxsat berilmaydi. F500 avtomobillari anʼanaviy amortizatorlar oʻrniga silindrsimon kanistrda joylashgan juda oddiy elastomerikdan foydalanadi. Qoidalarga koʻra elastomerning qalinligi 2 „diametri 1“ boʻlishi kerak, ammo elastomerik kamonlarning boshqacha dizaynlari keng tarqalgan. Bundan tashqari, har bir shassi ishlab chiqaruvchisi oʻlchov cheklovlariga rioya qiladigan oʻz dizayni boʻyicha kuzovlarni ishlab chiqaradi. Ushbu qoidalar nisbatan arzon narxlarda juda raqobatbardosh poyga oʻtkazish imkonini beradi, bu esa avtomobilni sozlash koʻnikmalarini kafolatlaydi.
F500 dvigatellari[tahrir | manbasini tahrirlash]
Formula 500 avtomobillari ikki silindrli, suv bilan sovutilgan ikki taktli dvigatel bilan jihozlangan. Zamonaviy avtomobillar Rotax 494 yoki Ski-Doo avtomobillari uchun ishlab chiqarilgan Rotax 493 dan foydalanadi. Hozirgi kunda asosan tadbirlar uchun ishlatiladigan eski avtomobillar Kawasaki 440/A dvigatelidan foydalangan. AMW 500L-85/250-2 R2c dvigatellaridan Formula 500 poygalarida foydalanish mumkin boʻlsa-da, kamdan-kam qoʻllaniladi.
Kawasaki tomonidan ishlab chiqarilgan Kawasaki 440/A dvigateli 38 mm Mikuni VM seriyali karburatorlar va sozlangan qoʻsh egzozdan foydalanadigan 436 cc pistonli portli dvigateldir. Ushbu dvigatel hozirga kelib yoʻl poygalarida raqobatbardosh boʻlmasa-da, u hali ham Solo II va Autocross tadbirlarida keng qoʻllaniladi. AMWdan tashqari barcha F500 dvigatellari singari, Kawasaki dastlab qor ustida harakatlanadigan avtomobil dvigateli sifatida ishlab chiqarilgan. U 1980-yillarning boshidan beri ishlab chiqarilmaydi. Ushbu dvigatellar uchun ehtiyot qismlarni topish qiyinlashmoqda.
Two Stroke International tomonidan ishlab chiqarilgan AMW 500L-85 dvigateli F500ga 1994-yilda taqdim etilgan. Bu 38 mm Mikuni SuperBN egizak karburatorlardan foydalangan holda ishlatiladigan 497 kub hajmli dvigateldir. Ushbu kattaroq, kuchliroq dvigatellarning ishlashini avvalgi dvigatellarga mos ravishda ushlab turish uchun SCCA AMW dvigatelida maxsus Y egzoz manifoldi va bitta sozlangan quvurdan foydalanishni talab qiladi[2]. F500-da ishlatiladigan boshqa dvigatellardan farqli oʻlaroq, AMW dvigateli yengil samolyot dvigatelining hosilasidir. Ushbu dvigatel hozirgi kunda ishlab chiqarilmaydi.
F500 uzatish vositalari[tahrir | manbasini tahrirlash]
F500 avtomobillarida ishlatiladiganga oʻxshash ilgʻor doimiy oʻzgaruvchan uzatma (CVT)dan foydalanadi.
