Xa abantu bethetha ngeemoto ezinamavili amathathu kunye neelori ezincinci kunye neeveni, badla ngokuthi le axle idada ngokupheleleyo, kwaye loo axle idada kancinci. Kuthetha ukuthini "i-full float" kunye ne-"semi-float" apha? Masiphendule lo mbuzo ungezantsi.
Oko kubizwa ngokuba yi-"full-floating" kunye ne-"semi-floating" kubhekisa kuhlobo lwenkxaso yokufaka kwi-axle shafts zeemoto. Njengoko sonke sisazi, i-half shaft yi-shaft eqinileyo ehambisa i-torque phakathi kwe-differential kunye namavili okuqhuba. Icala layo langaphakathi liqhagamshelwe kwi-side gear nge-spline, kwaye icala langaphandle liqhagamshelwe kwi-hub yevili lokuqhuba nge-flange. Ekubeni i-half shaft kufuneka ithwale i-torque enkulu kakhulu, amandla ayo kufuneka abe phezulu kakhulu. Ngokubanzi, intsimbi ye-alloy efana ne-40Cr, 40CrMo okanye i-40MnB isetyenziselwa ukucima nokulungisa kunye nonyango lokucima oluphezulu. Ukugaya, i-core inobunzima obuhle, inokumelana ne-torque enkulu, kwaye inokumelana nomthwalo othile wokuchaphazeleka, onokuhlangabezana neemfuno zeemoto phantsi kweemeko ezahlukeneyo.
Ngokweentlobo ezahlukeneyo zokuxhasa ze-half shafts, i-half shafts zahlulwe zibe ziintlobo ezimbini: "i-full floating" kunye ne-"semi-floating". I-full-floating axle kunye ne-semi-floating axle esihlala sibhekisa kuzo ngokwenene zibhekisa kuhlobo lwe-half-shaft. "I-Float" apha ibhekisa kumthwalo ogobileyo emva kokuba i-axle shaft isusiwe.
Oko kubizwa ngokuba yi-full-floating half shaft kuthetha ukuba i-half shaft ithwala i-torque kuphela kwaye ayithwali mzuzu wokugoba. Icala langaphakathi le-half shaft enjalo liqhagamshelwe kwi-differential side gear ngokusebenzisa ii-splines, kwaye icala langaphandle line-flange plate, eqiniswe ne-wheel hub ngee-bolts, kwaye i-wheel hub ifakwe kwi-axle ngee-roller bearings ezimbini ezithambileyo. Ngale ndlela, ukutshixiza kunye nokungcangcazela okwahlukeneyo kumavili, kunye nobunzima besithuthi, kudluliselwa ukusuka kumavili ukuya kwii-hubs uze uye kwii-axles, ezithi ekugqibeleni zithwalwe zii-axle housings. Ii-axle shaft zidlulisela nje i-torque ukusuka kwi-differential ukuya kumavili ukuze kuqhutywe imoto. Kule nkqubo, omabini amacala e-half shaft athwala i-torque kuphela ngaphandle komzuzu wokugoba, ngoko ke ibizwa ngokuba yi-"full floating". Umfanekiso olandelayo ubonisa ulwakhiwo kunye nofakelo lwe-full-floating half-shaft yemoto. Uphawu lwayo lolwakhiwo kukuba i-wheel hub ifakwe kwi-axle ngee-roller bearings ezimbini ezi-tapered, ivili lifakwe kwi-wheel hub, amandla axhasayo adluliselwa ngqo kwi-axle, kwaye i-half-shaft idlula. Izikrufu ezisibhozo ziqhotyoshelwe kwi-hub kwaye zidlulisela i-torque kwi-hub, ziqhuba ivili ukuba lijike.
I-half shaft egcweleyo kulula ukuyiqhaqha nokuyitshintsha, kwaye i-half shaft inokukhutshwa kuphela ngokususa ii-fixing bolts ezixhonywe kwi-flange plate ye-half shaft. Nangona kunjalo, ubunzima bonke bemoto emva kokususa i-half-axle buxhaswa yi-axle housing, kwaye isenokumiswa emhlabeni ngokuthembekileyo; ingxaki kukuba isakhiwo sinzima kwaye umgangatho weendawo mkhulu. Lolona hlobo lusetyenziswa kakhulu kwiimoto, kwaye uninzi lweelori ezilula, eziphakathi nezinzima, izithuthi ezingaphandle kwendlela kunye neemoto zabakhweli zisebenzisa olu hlobo lwe-axle shaft.
Oko kubizwa ngokuba yi-semi-floating half shaft kuthetha ukuba i-half shaft ayithwali nje kuphela i-torque, kodwa ikwathwala nexesha lokugoba. Icala langaphakathi le-axle shaft liqhagamshelwe kwi-differential side gear ngokusebenzisa ii-splines, isiphelo sangaphandle se-axle shaft sixhaswa kwi-axle housing nge-bearing, kwaye ivili lifakwe ngokuqinileyo kwi-cantilever kwisiphelo sangaphandle se-axle shaft. Ngale ndlela, amandla ahlukeneyo asebenza kumavili kunye namaxesha okugoba avelayo adluliselwa ngokuthe ngqo kwi-half shafts, aze afike kwi-drive axle housing ngee-bearings. Xa imoto isebenza, i-half shafts ayiqhubi nje kuphela amavili ukuba ajikeleze, kodwa ikwaqhuba namavili ukuba ajikeleze. Ukuxhasa ubunzima obupheleleyo bemoto. Isiphelo sangaphakathi se-half shaft sithwala kuphela i-torque kodwa kungekhona ixesha lokugoba, ngelixa isiphelo sangaphandle sithwala zombini i-torque kunye nexesha lokugoba elipheleleyo, ngoko ke kuthiwa "yi-semi-floating". Umfanekiso olandelayo ubonisa ulwakhiwo kunye nofakelo lwe-semi-floating semi-axle yemoto. Uphawu lwayo lolwakhiwo kukuba isiphelo sangaphandle sizinzile kwaye sixhaswe kwi-tapered roller bearing enomphezulu othe tyaba kunye nesitshixo kunye ne-hub, kwaye amandla e-axial angaphandle aqhutywa yi-tapered roller bearing. I-Bearing, amandla e-axial angaphakathi adluliselwa kwi-tapered roller bearing ye-half shaft esecaleni kwelinye icala nge-slider.
Isakhiwo senkxaso yesiqingatha se-shaft esintantayo sincinci kwaye silula, kodwa amandla esiqingatha se-shaft ayinkimbinkimbi, kwaye ukuqhekeka kunye nokuhlanganiswa akunangxaki. Ukuba ii-axle shafts zisusiwe, imoto ayinakuxhaswa emhlabeni. Ngokubanzi inokusetyenziswa kuphela kwiiveni ezincinci kunye nezithuthi ezilula ezinomthwalo wezithuthi ezincinci, ububanzi obuncinci bevili kunye ne-axle edibeneyo yangasemva, njenge-Wu ling series eqhelekileyo kunye ne-Song hua jiang series.
