Okokuqala, makhe sijonge ukuba ziyintoni na izikrufu zamatayara kunye nokuba zeziphi izinto ezizenzayo. Izikrufu zamatayara zibhekisa kwizikrufu ezifakwe kwihabhu yamavili kwaye zidibanisa ivili, idiski yebrake (idrama yebrake) kunye nehabhu yamavili. Umsebenzi wayo kukudibanisa ngokuthembekileyo amavili, iidiski zebrake (iidrama zebrake) kunye neehub kunye. Njengoko sonke sisazi, ubunzima bemoto buthwalwa ngamavili, ngoko ke unxibelelwano phakathi kwamavili nomzimba lufezekiswa ngezi krufu. Ke ngoko, ezi krufu zamatayara zithwala ubunzima bemoto yonke, kwaye zikwadlulisela i-torque output ukusuka kwi-gearbox ukuya kumavili, aphantsi kwesenzo esiphindwe kabini soxinzelelo kunye namandla okucheba ngaxeshanye.
Ulwakhiwo lwesikrufu setayara lulula kakhulu, oluqulunqwe sisikrufu, inati kunye newasher. Ngokwezakhiwo ezahlukeneyo zesikrufu, sinokwahlulwa sibe ziibolti ezinentloko enye kunye neebolti ezinentloko ezimbini. Uninzi lweemoto zangoku ziibolti ezinentloko enye, kwaye iibolti zestud zihlala zisetyenziswa kwiilori ezincinci neziphakathi. Kukho iindlela ezimbini zokufakela iibolti ezinentloko enye. Enye yi-hub bolt + nut. Ibolti iqiniswe kwihabhu nge-interference fit, kwaye emva koko ivili liqiniswe yinati. Ngokubanzi, iimoto zaseJapan naseKorea zisetyenziswa kakhulu, kwaye uninzi lweelori nazo ziyayisebenzisa. ngale ndlela. Inzuzo yale ndlela kukuba ivili kulula ukulifumana, ukuqhaqha nokuhlanganisa ivili kulula, kwaye ukhuseleko luphezulu. Ingxaki kukuba ukutshintshwa kwezikrufu zetayara kunzima ngakumbi, kwaye ezinye kufuneka ziqhaqhe ihabhu yevili; Isikrufu setayara siqiniswe ngqo kwihabhu yevili, esetyenziswa ngokubanzi kwiimoto ezincinci zaseYurophu naseMelika. Inzuzo yale ndlela kukuba kulula ukuyiqhaqha nokutshintsha izikrufu zetayara. Ingxaki kukuba ukhuseleko lubi kancinci. Ukuba izikrufu zamatayara ziphinda ziqhekeke zize zifakwe, imisonto ekwihabhu iya konakala, ngoko ke ihabhu kufuneka itshintshwe.
Izikrufu zamatayara eemoto zihlala zenziwe ngentsimbi enamandla kakhulu. Umgangatho wamandla esikrufu uprintwa entlokweni yesikrufu samatayara. Kukho i-8.8, 10.9, kunye ne-12.9. Okukhona ixabiso lilikhulu, kokukhona amandla aphezulu. Apha, i-8.8, 10.9, kunye ne-12.9 zibhekisa kwileyibhile yomgangatho wokusebenza kwebholiti, equlathe amanani amabini, amele ngokwahlukeneyo ixabiso lamandla okutsalwa kunye nomlinganiselo wokukhupha wezinto zebholiti, ngokubanzi ezichazwa yi-"XY", njenge-4.8, 8.8, 10.9, 12.9 njalo njalo. Amandla okutsalwa kweebholiti ezinenqanaba lokusebenza elingu-8.8 yi-800MPa, umlinganiselo wokukhupha yi-0.8, kwaye amandla okukhupha yi-800×0.8=640MPa; amandla okutsalwa kweebholithi ezinenqanaba lokusebenza eliyi-10.9 yi-1000MPa, umlinganiselo wesivuno yi-0.9, kwaye amandla esivuno yi-1000×0.9= 900MPa
Ezinye njalo njalo. Ngokubanzi, amandla e-8.8 nangaphezulu, izinto zebholithi yintsimbi ye-alloy enekhabhoni ephantsi okanye intsimbi yekhabhoni ephakathi, kwaye unyango lobushushu lubizwa ngokuba yi-high strength bolt. Izikrufu zamatayara emoto zonke zi-high-strength bolts. Iimodeli ezahlukeneyo kunye nemithwalo eyahlukeneyo zinamandla ahlukeneyo ebholithi. I-10.9 yeyona ixhaphakileyo, i-8.8 ngokubanzi ihambelana neemodeli ezisezantsi, kwaye i-12.9 ngokubanzi ihambelana neelori ezinzima.
