Inkqubo yoThutho:
Ibandakanya izinto ezifana ne-clutch, i-gearbox, i-universal joints (umzekelo, ii-universal joints, driveshafts), i-final drive, differential, kunye ne-half{2}}shafts. Owona msebenzi wayo kukuhambisa amandla ukusuka kwi-injini ukuya kumavili okuqhuba isithuthi, ukwenza imisebenzi efana nokunciphisa, ukutshintsha igiya, ukutshintsha indlela, ukucinywa kwamandla{4}ukucima, phakathi{5}}nokwahluka kwevili, kunye{6}}nokwahluka kwe-axle, ukuqinisekisa ukuba isithuthi siyakwazi ukusebenza ngokuqhelekileyo phantsi kweemeko ezahlukeneyo.
Inkqubo yoMbaleki:
Iquka izinto ezifana nesakhelo, ii-asi (kubandakanywa ii-asi zangaphambili nezingasemva), amavili, kunye nokuxhonywa. Umsebenzi oyintloko wenkqubo yomgijimi kukufumana amandla kwi-transmission system, ukuvelisa i-traction ngokusebenzisa intsebenziswano phakathi kwamavili okuqhuba kunye nomgangatho wendlela, ukuqinisekisa ukuhamba kwesithuthi esiqhelekileyo; iphinda ithwale ubunzima obupheleleyo besithuthi kunye namandla okuphendula ukusuka emhlabeni, ukunciphisa impembelelo yeendlela ezingalinganiyo emzimbeni, ukunciphisa ukungcangcazela ngexesha lokuqhuba, ukugcina ukuzinza, kunye nokusebenza kunye nenkqubo yokulawula ukuqinisekisa ukuzinza kokusingatha isithuthi.
Inkqubo yokulawula:
Kubandakanya izinto ezifana nevili lokuqhuba, ishafti yokuqhuba, ikholamu yokuqhuba, izixhobo zokuqhuba, iingalo zokuqhuba, iintsimbi zokubopha, iilinki zokutsala, kunye neentsimbi zokuqhuba. Umsebenzi ophambili wenkqubo yokuqhubela phambili kukulawula indlela yesithuthi ngokweenjongo zomqhubi, ukuqinisekisa ukuba isithuthi sinokuqhutywa njengoko kufuneka.
Inkqubo yokuqhobosha:
Ikakhulu iqulathe iinxalenye ezine: isixhobo sonikezelo lwamandla, isixhobo solawulo, isixhobo sothumelo, kunye neziqhoboshi (ezifana neepakedi zeebhuleki kunye neediski zeebhuleki). Owona msebenzi uphambili wenkqubo yokuqhobosha kukunciphisa ngenkani isantya sesithuthi, ukuthoba isantya okanye nokumisa isithuthi esihambayo, ukugcina isantya esizinzileyo kwisithuthi esihla sinyuka, nokugcina isithuthi esimileyo simile, ngaloo ndlela siqinisekisa ukhuseleko lokuqhuba.
