Mototsiklning asosiy tarkibi

A mototsikl mototsikli dan besh qismdan iborat: dvigatel, uzatish tizimi, yurish tizimi, freym tizimi va elektr asboblar uskunalari. The umumiy tuzilishi mototsikl va uning komponentlarining nomlari .

1. Xususiyatlari mototsikl dvigateli

(1) The motor is a two-stroke or four-stroke benzin motor.

(2) Adopt havo sovutish, u erda ikkita turdagi tabiiy havo sovutish va majburiy havo sovutish. The general model adopts the natural air-cooling cooling tayangan ta ta tayan gan havo esuvchi orqali silindr boshi va issiqlik cho't on on the cylindr liner to take the the heat during haydash paytida. In order to ta'minlash the cooling of the engine at past speed and starting, the high-power motorcycle engine adopts a forced air cooling method of installing a fan and an air berroud, and using forced air to blow the cooling fins.

(3) The speed of the engine is high, generally above 5000 rpm. The litr power (samarali quvvat per litr of engine displacement) is katta, umuman litr uchun 60 kilovatt atrofida 60 kilovatt soat. Bu shuni ko'rsatadiki mototsikl dvigatel a a yuqori daraja ning darajasi bo'ladi mustahkamlash va a kichik dvigatel hajmi.

(4) Dvigatel krankcase integral bilan the clutch and gearbox, and the structure is compact.

2. Tana

tanasi uch qismdan iborat 3a silindr bosh, silindr blok va krankcase. Silindr boshi alyuminiy qotishmasidan tayyorlangan va issiqlik cho'tkalari. The new four-stroke motorcy engine adopts of structure ust valf, zanjir drive va overhead camshaft. The material of the cylinder block is is asosan bimetal (alyuminiy issiqlik sink cast tashqarida the wear-chidamli cast temir silindr liner) to olish uchun olish yaxshiroq issiqlik dissipatsiya ta'siri. Ba'zi mototsikllar foydalanish wear-chidamli cast temir silindrlar, kabi Changjiang 750} va Jialing JH70. In ba'zi kichik mopedlar, masalan Yuhe brand YH50Q kichik ko'chirish (50 kub santimetr) dvigatellar, the ichki devor of the aluminum alloy cylinder is pli bilan 0,15 mm qattiq Struktura the chrome layer. The krankcase dan tayyorlangan alyuminiy qotishma die-casting va chap va o'ng qutilardan tarkib topgan . Ba'zi mototsikllar bor a bufer blok orasida issiqlik dissipation to lar bostirish the noise from the vibration of the heat sink.
