Njengoko sonke sisazi, iibholiti zeehabhu zizibophelelo ezibalulekileyo kwimoto. Musa ukuyijongela phantsi le nut yomgunyathi. Kwiminyaka emininzi eyadlulayo, iibholiti zomgunyathi kunye namandongomane afunekayo kwiimoto ezihlaziyiweyo zasekhaya zazithengwa phesheya, kwaye ixabiso laliphezulu. Emva kwexesha, iibholithi ezenziwe ngomyinge zafumaneka ngokuthe ngcembe. Ixabiso liye lehla laya kumgangatho abantu abaqhelekileyo abanokuwamkela.
Ngokuqhelekileyo sinokutshintsha kuphela i-nut (kufuneka ihambelane namazinyo e-bolt yokulungisa). Kwezinye izithuthi, iintambo zangaphakathi (ezilingana nomsebenzi we-bolt caps) zilungiselelwe kwi-disc ye-axle, kwaye iibholiti zikhutshwe xa i-hub isusiwe.
Le yindlela yokuqinisa kunye nokulungiswa kweebholithi zehabhu ezibunjiweyo, ezizezodidi lwe-axle disc bolt, kwaye iibholiti zigxininiswe kwi-axle disc.
Xa siqhaqha ithambo levili, into esiyisusayo ngokwenene ngumnqwazi webholt. Ke ngoko, ukuba ufuna ukunyusela kuqhagamshelo lwebholiti yomgunyathi, kufuneka uthenge kuphela i-nut ehambelanayo.
Okokuqala, umgangatho we-aluminium alloy forged bolts ungaphezu kokuphindwe kabini ukukhanya njengeebholiti zangaphambili. Imoto yokuqala idinga iibholiti zentsimbi ezili-16 zizonke. Emva kokutshintsha zonke iibholiti ezibunjiweyo ze-aluminium, ubunzima bulingana kuphela neebholiti zentsimbi ezisi-8 zemoto yokuqala. Nangona ubunzima obuncitshisiweyo bukhawulelwe, bungakanani ubuninzi obungaxutywanga bunokuncitshiswa?
Okwesibini, ukuxhatshazwa kwe-corrosion of bolts forged bolts kungcono kuneebholiti zetsimbi. I-aluminiyam ingxubevange iibholiti kunye namantongomane adityaniswe nenkqubo ye-oxidation ye-aluminiyam enodizekile, enokumelana ne-corrosion enamandla.
Okwesithathu, amandla eebholiti ezibunjiweyo angcono kuneebholiti zetsimbi. Kodwa kufuneka ungathengi iibholiti kunye namandongomane aphantsi kunye nawomgunyathi. Xa uthenga, kufuneka udibane nomthengisi malunga neenkcukacha kunye neempawu zeebholiti kunye namantongomane.
Iibholiti ezenziweyo zizibophelelo ezibalulekileyo kumavili emoto. Umgangatho weebholithi uya kuchaphazela ngqo uhlobo lwesithuthi. Akukho mntu ufuna ukwenza iingozi ezingeyomfuneko ngenxa yengxaki yomgangatho webholiti.
