Choyamba, tiyeni tiwone zomwe zomangira matayala zilili ndi zomwe zimachita. Zomangira matayala zimatanthauza zomangira zomwe zimayikidwa pa wheel hub ndikulumikiza gudumu, brake disc (brake drum) ndi wheel hub. Ntchito yake ndikulumikiza mawilo, ma brake disc (brake drums) ndi ma hub pamodzi modalirika. Monga tonse tikudziwira, kulemera kwa galimoto kumayendetsedwa ndi mawilo, kotero kulumikizana pakati pa mawilo ndi thupi kumachitika kudzera mu zomangira izi. Chifukwa chake, zomangira matayala izi zimanyamula kulemera kwa galimoto yonse, komanso zimatumiza mphamvu yotulutsa kuchokera ku gearbox kupita ku mawilo, omwe amakhudzidwa ndi mphamvu ziwiri zomangika komanso nthawi imodzi.
Kapangidwe ka sikuru ya tayala ndi kosavuta kwambiri, komwe kali ndi sikuru, nati ndi chotsukira. Malinga ndi kapangidwe kosiyana ka sikuru, kakhozanso kugawidwa m'mabotolo okhala ndi mutu umodzi ndi mabotolo okhala ndi mutu umodzi. Magalimoto ambiri omwe alipo pano ndi mabotolo okhala ndi mutu umodzi, ndipo ma stud bolt nthawi zambiri amagwiritsidwa ntchito pamagalimoto ang'onoang'ono ndi apakatikati. Pali njira ziwiri zokhazikitsira ma botolo okhala ndi mutu umodzi. Imodzi ndi hub bolt + nati. Bolt imakhazikika pa hub ndi cholumikizira chosokoneza, kenako gudumu limakhazikika ndi nati. Nthawi zambiri, magalimoto aku Japan ndi aku Korea amagwiritsidwa ntchito kwambiri, ndipo magalimoto ambiri amagwiritsanso ntchito motere. Ubwino wa njira iyi ndikuti gudumu ndi losavuta kupeza, kusokoneza ndi kusonkhanitsa gudumu kumakhala kosavuta, ndipo chitetezo chimakhala chokwera. Choyipa ndichakuti kusintha ma screw a matayala kumakhala kovuta kwambiri, ndipo ena amafunika kusokoneza hub ya magudumu; Sikuru ya tayala imakulungidwa mwachindunji pa hub ya magudumu, yomwe nthawi zambiri imagwiritsidwa ntchito m'magalimoto ang'onoang'ono aku Europe ndi America. Ubwino wa njira iyi ndikuti ndikosavuta kusokoneza ndikusintha ma screw a matayala. Vuto lake ndilakuti chitetezo chimakhala choyipa pang'ono. Ngati zomangira za matayala zichotsedwa mobwerezabwereza ndikuyikidwa, ulusi womwe uli pa hub udzawonongeka, kotero hub iyenera kusinthidwa.
Zomangira za matayala a galimoto nthawi zambiri zimapangidwa ndi chitsulo champhamvu kwambiri. Mphamvu ya screw imasindikizidwa pamutu wa screw ya tayala. Pali 8.8, 10.9, ndi 12.9. Mtengo ukakhala waukulu, mphamvu imakwera. Pano, 8.8, 10.9, ndi 12.9 zimatanthauza chizindikiro cha grade performance cha bolt, chomwe chili ndi manambala awiri, omwe motsatana akuyimira mphamvu yolimba yolimba ndi chiŵerengero cha yield cha zinthu za bolt, zomwe nthawi zambiri zimafotokozedwa ndi "XY", monga 4.8, 8.8, 10.9, 12.9 ndi zina zotero. Mphamvu yolimba ya mabolts yokhala ndi grade performance 8.8 ndi 800MPa, yield ratio ndi 0.8, ndipo yield strength ndi 800×0.8=640MPa; Mphamvu yokoka ya mabolts yokhala ndi giredi yogwira ntchito 10.9 ndi 1000MPa, chiŵerengero cha yield ndi 0.9, ndipo mphamvu yogwira ntchito ndi 1000×0.9 = 900MPa
Zina ndi zina zotero. Kawirikawiri, mphamvu ya 8.8 ndi kupitirira apo, zinthu za bolt ndi chitsulo chopanda kaboni kapena chitsulo chapakati cha kaboni, ndipo chithandizo cha kutentha chimatchedwa bolt yamphamvu kwambiri. Zomangira matayala a galimoto zonse ndi mabolt amphamvu kwambiri. Mitundu yosiyanasiyana ndi katundu wosiyanasiyana zimakhala ndi mphamvu zosiyana za bolt. 10.9 ndiye yodziwika kwambiri, 8.8 nthawi zambiri imafanana ndi mitundu yotsika, ndipo 12.9 nthawi zambiri imafanana ndi magalimoto olemera.
