Okokuqala, makhe sijonge ukuba zeziphi izikrufu zamavili kwaye zenza ntoni.Izikrufu zamavili zibhekisa kwizikrufu ezifakwe kwihabhu yevili kwaye ziqhagamshele ivili, idiski yebrake (igubu lebrake) kunye nehabhu yevili.Umsebenzi wayo kukudibanisa ngokuthembekileyo amavili, ii-discs ze-brake (iidramu ze-brake) kunye nee-hubs kunye.Njengoko sonke sisazi, ubunzima bemoto ekugqibeleni buthwalwa ngamavili, ngoko ke unxibelelwano phakathi kwamavili kunye nomzimba lufezekiswa ngezikrufu.Ke ngoko, ezi zikrufu zamavili zithwala ubunzima bemoto yonke, kwaye zikwahambisa itorque ukusuka kwibhokisi yegiya ukuya kumavili, axhomekeke kwisenzo esiphindwe kabini soxinzelelo kunye namandla okucheba ngaxeshanye.
Isakhiwo se-screw yesondo silula kakhulu, esakhiwe nge-screw, i-nut kunye ne-washer.Ngokwezikruphu ezahlukeneyo zezakhiwo, zinokuphinda zihlulwe zibe ziibholiti ezinentloko enye kunye neebholiti ezinentloko ephindwe kabini.Uninzi lweemoto zangoku ziibholiti ezinentloko enye, kwaye iibholiti ze-stud zisetyenziswa ngokubanzi kwiilori ezincinci neziphakathi.Kukho iindlela ezimbini zokufakela iibholithi ezinentloko enye.Enye yi hub bolt + nut.I-bolt igxininiswe kwi-hub kunye ne-interference fit, kwaye ke isondo lilungiswe yi-nut.Ngokubanzi, iimoto zaseJapan nezaseKorea zisetyenziswa kakhulu, kwaye uninzi lwelori ziyayisebenzisa.Le ndlela.Inzuzo yale ndlela kukuba ivili kulula ukuyifumana, ukuchithwa kunye nokuhlanganisana kwevili kulula, kwaye ukhuseleko luphezulu.Ukungalungi kukuba ukutshintshwa kwezikrufu zamavili kuyinkathazo ngakumbi, kwaye ezinye zifuna ukuqhaqha i-hub yevili;Isikrufu sevili sikrwelwe ngokuthe ngqo kwihabhu yevili, esetyenziswa ngokubanzi kwiimoto ezincinci zaseYurophu naseMelika.Inzuzo yale ndlela kukuba kulula ukuqhaqha kunye nokutshintsha izikrufu zamavili.Ububi kukuba ukhuseleko lubi kakhulu.Ukuba i-screws yevili ihlanjululwa ngokuphindaphindiweyo kwaye ifakwe, imicu kwi-hub iya konakala, ngoko i-hub kufuneka itshintshwe.
Izikrufu zamavili emoto ngokuqhelekileyo zenziwe ngentsimbi ephezulu.Ibakala lamandla lesikrufu liprintwa kwintloko yesikrufu sevili.Kukho u-8.8, 10.9, kunye no-12.9.Ixabiso elikhulu, amandla aphezulu.Apha, i-8.8, 10.9, kunye ne-12.9 zibhekisela kwileyibhile yebakala lokusebenza yebholithi, equlathe amanani amabini, ngokulandelelanayo amele ixabiso le-tensile lamandla kunye nomlinganiselo wesivuno semathiriyeli yebholt, ebonakaliswa ngokubanzi ngokuthi "XY", njenge-4.8 , 8.8, 10.9, 12.9 njalo njalo.Amandla e-tensile eebholithi kunye nebakala lokusebenza 8.8 yi-800MPa, umlinganiselo wesivuno ngu-0.8, kwaye amandla emveliso yi-800 × 0.8 = 640MPa;Amandla okuqina eebholithi kunye nenqanaba lokusebenza 10.9 yi-1000MPa, umlinganiselo wesivuno ngu-0.9, kwaye amandla esivuno yi-1000×0.9=900MPa
Abanye njalo njalo.Ngokuqhelekileyo, amandla e-8.8 nangaphezulu, i-bolt material yintsimbi ephantsi ye-carbon alloy okanye i-medium carbon steel, kwaye unyango lobushushu lubizwa ngokuba yi-bolt yamandla aphezulu.Izikrufu zamatayara emoto zonke ziibholiti zokuqina okuphezulu.Iimodeli ezahlukeneyo kunye nemithwalo eyahlukeneyo inamandla ahlukeneyo ahambelana ne-bolt.I-10.9 yeyona nto ixhaphakileyo, i-8.8 ihambelana ngokubanzi nemodeli ephantsi, kwaye i-12.9 ihambelana ngokubanzi kwiilori ezinzima.phezulu.
