Nkuko twese tubizi, imigozi y'imodoka ni ingenzi cyane ku modoka. Ntugasuzugure iyi migozi y'ibumba. Mu myaka myinshi ishize, imigozi n'imigozi by'ibumba bikenewe ku modoka zo mu gihugu zaguzwe mu mahanga, kandi igiciro cyari kiri hejuru. Nyuma yaho, imigozi y'ibumba yo mu gihugu yagiye iboneka buhoro buhoro. Igiciro cyaragabanutse ku rwego abantu basanzwe bashobora kwemera.
Ubusanzwe dushobora gusimbuza nut gusa (tugomba guhuza n'amenyo ya bolt yo kuyishyiraho). Mu binyabiziga bimwe na bimwe, insinga z'imbere (zingana n'imikorere y'imigozi ya bolt) zitegurwa kuri disiki y'umurambararo, kandi bolts zirakurwaho iyo hub ikuweho.
Ubu ni uburyo bwo gufata no gufunga bwa forgot hub bolts, bugizwe n'ubwoko bwa axle disc bolts, kandi bolts ziba zifatanye na axle disc.
Iyo dusenye igufwa ry'uruziga, icyo dukuramo ni umupfundikizo w'umunyururu. Kubwibyo, niba ushaka kuvugurura ukajya kuri forgouble bolt connection, ugomba kugura gusa nut ijyanye nayo.
Ubwa mbere, ubwiza bw'amaboliti ya aluminiyumu akoze mu buryo bwa aloyide ni inshuro zirenze ebyiri zoroheje ugereranyije n'amaboliti ya mbere. Imodoka ya mbere ikenera amaboliti y'icyuma 16 yose hamwe. Nyuma yo kuyasimbuza yose hamwe n'amaboliti ya aluminiyumu akoze mu buryo bwa aloyide, uburemere bungana gusa n'amaboliti 8 y'icyuma y'imodoka ya mbere. Nubwo uburemere bwagabanutse ari buke, uburemere butarashyirwa ku isoko bushobora kugabanuka bungana iki?
Icya kabiri, ubushobozi bwo kurwanya ingese bw'amaboliti acuzwe buruta ubw'ibyuma. Amaboliti n'imbuto byakozwe muri aluminiyumu bihuzwa n'uburyo bwo kugabanya ingese bwa aluminiyumu, bufite ubushobozi bwo kurwanya ingese cyane.
Icya gatatu, imbaraga z'amaboliti acuzwe ni nziza kuruta iz'amaboliti y'icyuma. Ariko ntugomba kugura amaboliti n'imbuto zicuzwe nabi kandi z'impimbano. Mu gihe uguze, ugomba kugisha inama umugurisha ku bipimo n'ibirango by'amaboliti n'imbuto.
Bolts zikozwe mu buryo bwa "filled bolts" ni ingenzi ku mapine y'imodoka. Ubwiza bw'amabolts buzagira ingaruka ku miterere y'imodoka. Nta muntu ushaka guteza impanuka zitari ngombwa bitewe n'ikibazo cy'ubwiza bw'amabolts.
