Monga tonse tikudziwa, ma bolts ndi zomangira zofunika pagalimoto. Osapeputsa mtedza wabodzawu. Zaka zambiri zapitazo, mabawuti abodza ndi mtedza wofunikira pamagalimoto okonzedwanso m'nyumba anali kugula kuchokera kunja, ndipo mtengo wake unalinso wokwera. Pambuyo pake, mabawuti opangira m'nyumba pang'onopang'ono adayamba kupezeka. Mtengo watsikira pamlingo womwe anthu wamba angavomereze.
Nthawi zambiri timatha kusintha mtedza (uyenera kufanana ndi mano a bolt). M'magalimoto ena, ulusi wamkati (wofanana ndi ntchito ya zisoti za bolt) zimakonzedwa pa axle disc, ndipo ma bolts amamasulidwa pamene thumba likuchotsedwa.
Iyi ndi njira yomangirira ndi kukonza ya ma bolts opangira, omwe ndi amtundu wa axle disc bolt, ndipo mabawuti amakhazikika pa axle disc.
Tikamachotsa fupa la gudumu, zomwe timachotsa ndi kapu ya bawuti. Chifukwa chake, ngati mukufuna kupititsa patsogolo kulumikizana kwa bawuti, muyenera kugula mtedza wofananira.
Choyamba, mtundu wa aluminiyamu alloy forged bolts ndi wopepuka kuwirikiza kawiri kuposa mabawuti oyambilira. Galimoto yoyambirira imafuna mabawuti 16 azitsulo. Pambuyo powasintha onse ndi ma bolts opangidwa ndi aluminiyamu, kulemera kwake kumangofanana ndi mabawuti 8 azitsulo agalimoto yoyambirira. Ngakhale kuti misa yochepetsedwayo ndi yochepa, ndi zochuluka bwanji zomwe sizingapangidwe zingachepetsedwe?
Chachiwiri, kukana kwa dzimbiri kwa mabawuti opangidwa ndikwabwino kuposa ma bawuti achitsulo. Aluminium alloy forged bolts ndi mtedza amaphatikizidwa ndi anodized aluminium oxidation process, yomwe imakhala ndi kukana kwa dzimbiri.
Chachitatu, mphamvu za ma bolts opangidwa ndi zabwino kuposa zazitsulo zazitsulo. Koma musagule mabawuti ndi mtedza wabodza wotsikirapo kapena wabodza. Mukamagula, muyenera kufunsa wogulitsa zatsatanetsatane ndi mtundu wa ma bolts ndi mtedza.
Maboti opangidwa ndi zida ndizofunikira zomangira pamawilo agalimoto. Ubwino wa ma bolts udzakhudza mwachindunji mawonekedwe agalimoto. Palibe amene amafuna kuyambitsa ngozi zosafunikira chifukwa cha vuto la bolt.
