Video narration
Mod par car jhukti hai. Tez brake mein sharir aage khinchta hai. Gaddhe par jhatka aata hai, phir bhi pahie sadak se jude rehte hain aur aap niyantran mein rehte hain. Yahin chassis kaam karta hai. Yeh sirf frame nahin; sadak aur cabin ke beech bal sambhalne wala aadhar hai. Sadak ka asar tyres se aata hai; suspension pahiyon ki gati niyantrit karke jhatke sharir se alag karta hai. Isi se steering disha badalti hai, brakes gati ghatate hain, aur body tiki rehti hai. Isliye engine car ki neenv nahin hai. Woh isi sanrachna par laga hota hai; car kaise mudegi, rukegi aur uchhal sambhalegi, ismein chassis ki badi bhoomika hai. Kai aadhunik cars mein alag frame bhi nahin hota. Unibody mein body shell aur sanrachna ek saath bani hoti hain. Yaad rakhiye - chassis woh aadhar hai jo chaar tyres ke sadak-sampark ko niyantrit gati mein badalta hai.
