Kodi choyamwitsa mantha chimagwira ntchito bwanji?
Ma shock absorber amagwiritsidwa ntchito kuletsa shock yomwe imachitika chifukwa cha kasupe akachira ku shock absorber ndi shock over the road. Amagwiritsidwa ntchito kwambiri m'magalimoto kuti afulumizitse shock absorber ya chimango ndi thupi lake komanso kukonza chitonthozo cha galimoto. Pambuyo pa road surface yosagwirizana, ngakhale kuti shock absorber ya kasupe imatha kusefa kugwedezeka kwa msewu, kasupeyo imakhalanso ndi mayendedwe obwerezabwereza, ndipo shock absorber imagwiritsidwa ntchito kuletsa shock absorber kulumpha.
Pofuna kukonza chitonthozo cha galimoto pamene chinthu chopindika chikugwedezeka ndi kugwedezeka, chopopera cha chinthu chopindika chimayikidwa pamodzi mu chopopera kuti chichepetse kugwedezeka. Chopopera cha kugwedezeka chomwe chimagwiritsidwa ntchito mu dongosolo loyimitsidwa ndi chopopera cha hydraulic, ndipo mfundo yake yogwirira ntchito ndi yakuti pamene kugwedezeka kwa kayendedwe kachitika pakati pa chimango (kapena thupi) ndi shaft, pisitoni imapita mmwamba ndi pansi mkati mwa chopopera cha kugwedezeka. Mafuta omwe ali mu chipinda chopopera cha kugwedezeka amayenda mobwerezabwereza kuchokera ku chipinda chimodzi kupita ku china kudzera m'mabowo osiyanasiyana. Panthawiyi, kukangana pakati pa khoma la dzenje ndi mafuta ndi kukangana kwamkati pakati pa mamolekyu a mafuta amapanga mphamvu yopopera pa kugwedezeka, kotero kuti mphamvu yopopera ya galimoto imasandulika mphamvu yotenthetsera mafuta, kenako imatengedwa ndi chopopera cha kugwedezeka ndikugawidwa mumlengalenga. Pamene gawo lodutsa mafuta ndi zinthu zina sizikusintha, mphamvu yopopera imawonjezera kapena kuchepetsa liwiro pakati pa chimango ndi shaft (kapena gudumu), zomwe zimagwirizana ndi kukhuthala kwa mafuta.
Kufotokozera kwa mfundo yogwirira ntchito ya chopopera cha silinda chogwira ntchito mbali zonse ziwiri: Mu kupopera kwa compression, zikutanthauza kuti gudumu la galimoto lili pafupi ndi thupi, chopopera cha shock chimakanikizidwa, ndipo pistoni yomwe ili mu chopopera cha shock imatsika pansi. Kuchuluka kwa pistoni m'munsi kumachepa ndipo kuthamanga kwa mafuta kumawonjezeka. Mafuta amadutsa mu valavu yoyenda kupita ku chipinda pamwamba pa pistoni (chipinda chapamwamba). Chipinda chapamwamba chimakhala ndi gawo la malo a pistoni, kotero kuchuluka kwa voliyumu ya chipinda chapamwamba kumakhala kochepa kuposa kuchuluka kochepa kwa chipinda chapansi, kenako gawo la mafuta limakankhira valavu yokakamiza kuti ibwerere ku silinda yosungiramo. Kuchuluka kwa mafuta a ma valve awa kumapanga mphamvu yonyowa ya kuyimitsidwa panthawi yopopera. Chopopera cha shock chikatambasulidwa, gudumulo limafanana ndi kusuntha kuchoka pa thupi, ndipo chopopera cha shock chimatambasulidwa. Pistoni ya chopopera cha shock imakwera mmwamba. Kuthamanga kwa mafuta m'chipinda chapamwamba cha pistoni kumakwera, valavu yoyenda imatsekedwa, ndipo mafuta m'chipinda chapamwamba amakankhira valavu yowonjezera kupita ku chipinda chapansi. Chifukwa cha kukhalapo kwa ndodo ya pistoni, kuchuluka kwa mafuta omwe amatuluka m'chipinda chapamwamba sikukwanira kudzaza kuchuluka kwa voliyumu ya chipinda chapansi. Chifukwa chachikulu ndi vacuum yomwe ili m'chipinda chapansi. Panthawiyi, mafuta omwe ali mu silinda yosungiramo zinthu amakankhira valavu yolipirira 7 m'chipinda chapansi kuti iwonjezere. Chifukwa cha mphamvu ya mavavu awa, kuyimitsidwa kumagwira ntchito ngati choletsa kuzizira panthawi yotambasula.
