Umsebenzi wesithuthi esinamavili angasemva
Umsebenzi ophambili we-hub bearing kukuthwala ubunzima kunye nokubonelela ngesikhokelo esichanekileyo sokujikeleza kwe-hub. Ithwala imithwalo ye-axial kunye ne-radial kwaye iyinxalenye ebaluleke kakhulu. Iibheringi zemveli ezisetyenziselwa amavili eemoto zenziwe ngeeseti ezimbini zeebheringi ze-roller ezithambileyo okanye iibheringi zebhola. Ukufakelwa, ukutshiza ioyile, ukutywina kunye nokulungiswa kokususwa kweebheringi konke kwenziwa kumgca wemveliso yemoto. Olu lwakhiwo lwenza kube nzima ukuhlanganisa abavelisi bemoto, lubiza kakhulu kwaye aluthembekanga. Ngaphezu koko, xa imoto igcinwa kwindawo yokulungisa, iibheringi nazo kufuneka zicocwe, zifakwe ioyile kwaye zilungiswe. Iiyunithi zeebheringi ze-Hub ziye zaphuhliswa ngokusekelwe kwiibheringi zebhola ezinxibelelanayo ze-angular kunye neebheringi ze-roller ezithambileyo. Zidibanisa iiseti ezimbini zeebheringi zibe yinye, zibonisa ukusebenza kakuhle kokuhlanganisa, akukho mfuneko yokulungiswa kwe-clearance, ubunzima obulula, isakhiwo esincinci, umthamo omkhulu womthwalo, ukufakwa kwangaphambili kwegrisi njengeebheringi ezivaliweyo, akukho mfuneko yokuvalwa kwe-hub yangaphandle, kwaye akukho mfuneko yokugcinwa. Ziye zasetyenziswa kakhulu kwiimoto. Kukwakho nomkhwa wokwandisa kancinci kancinci ukusetyenziswa kwayo kwiilori ezinzima.
Ngaphambili, ii-hub bearing zeemoto zazisetyenziswa kakhulu ngababini njengee-roller okanye ii-ball bearing ezine-tapered row enye. Ngophuhliso lwetekhnoloji, ii-hub units zeemoto bezisetyenziswa kakhulu kwiimoto. Ububanzi bokusetyenziswa kunye nomthamo wokusetyenziswa kwee-hub bearing units ziyanda imihla ngemihla, kwaye ngoku ziye zaphuhliswa zaya kwisizukulwana sesithathu: isizukulwana sokuqala sakhiwe zii-angular contact bearing ezine-double-row contact. Isizukulwana sesibini sine-flange kwindlela yangaphandle yokukhwela i-bearing, enokufakwa nje kwi-axle kwaye iqiniswe nge-nut. Kwenza ukugcinwa kweemoto kube lula. I-hub bearing unit yesizukulwana sesithathu isebenzisa i-bearing unit kunye ne-anti-lock braking system (ABS). I-hub unit yenzelwe i-inner flange kunye ne-outer flange. I-inner flange inamathele kwi-drive shaft ngee-bolts, ngelixa i-outer flange ifaka yonke i-bearing kunye. Ii-hub bearing okanye ii-hub units ezigugileyo okanye ezonakeleyo zinokubangela ukungaphumeleli okungafanelekanga nokubizayo kwesithuthi sakho ngexesha lokuqhuba, kwaye zide zibe yingxaki kukhuseleko lwakho.
Nceda uqaphele le micimbi ilandelayo xa usebenzisa kwaye ufaka ii-hub bearings:
Ukuqinisekisa ukhuseleko kunye nokuthembeka ngokupheleleyo, kuyacetyiswa ukuba uhlole rhoqo ii-hub bearings nokuba imoto ineminyaka emingaphi - qaphela iimpawu zesilumkiso zokuqala zokuguguleka kwee-bearings: kuquka nayiphi na ingxolo yokungqubana ngexesha lokujikeleza okanye ukucotha okungaqhelekanga kwamavili adibeneyo okuxhonywa xa ujika. Kwizithuthi eziqhuba amavili angasemva, kuyacetyiswa ukuba ii-front hub bearings zithanjiswe xa imoto ihambe iikhilomitha ezingama-38,000. Xa utshintsha inkqubo yokuqhobosha, jonga ii-bearings kwaye utshintshe izitywini zeoyile.
Ukuba uva ingxolo engaqhelekanga isuka kwindawo ye-hub bearing, into yokuqala neyona ibalulekileyo kukufumana indawo apho ingxolo isenzeka khona. Zininzi iindawo ezihambayo ezinokubangela ingxolo, okanye kusenokwenzeka ukuba ezinye iindawo ezijikelezayo zidibene neendawo ezingajikeleziyo. Ukuba kuqinisekisiwe ukuba ingxolo ivela kwi-bearing, i-bearing isenokuba yonakele kwaye kufuneka itshintshwe.
Ngenxa yokuba iimeko zokusebenza ezibangela ukungasebenzi kakuhle kweebheringi kumacala omabini ngenxa yehabhu yevili langaphambili ziyafana, kuyacetyiswa ukuba zitshintshwe ngababini nokuba ibheringi enye yonakele.
Iibheringi zeehabhu zinobuthathaka, kwaye nokuba kunjalo, kufuneka kusetyenziswe iindlela ezichanekileyo nezixhobo ezifanelekileyo. Ngexesha lokugcina, ukuthuthwa kunye nokufakelwa, izinto zebheringi akufuneki zonakaliswe. Ezinye iibheringi zifuna uxinzelelo olukhulu ukuze zicinezelwe, ngoko ke kufuneka izixhobo ezikhethekileyo. Qiniseka ukuba ubhekisa kwincwadi yemiyalelo yokwenziwa kweemoto.
Xa ufaka iibheringi, kufuneka zenziwe kwindawo ecocekileyo necocekileyo. Amasuntswana amancinci angena kwiibheringi nawo aya kunciphisa ubomi bawo bokusebenza. Kubaluleke kakhulu ukugcina indawo ecocekileyo xa utshintsha iibheringi. Akuvumelekanga ukubetha ibheringi ngesando. Lumka ungayiwisi ibheringi emhlabeni (okanye uyiphathe ngendlela engafanelekanga ngendlela efanayo). Ngaphambi kokufakwa, imeko yeshaft kunye nendlu yeebheringi nayo kufuneka ihlolwe. Nokuba ukuguguleka okuncinci kunokukhokelela ekungalingani kakuhle, ngaloo ndlela kubangele ukungaphumeleli kwangaphambi kwexesha kwebheringi.
Kwiiyunithi zeehabhu zokuthwala, musa ukuzama ukuqhekeza iihabhu zokuthwala okanye ukulungisa iiringi zokubopha zeeyunithi zeehabhu; kungenjalo, iiringi zokubopha zinokonakala, nto leyo evumela amanzi okanye uthuli ukuba lungene. Kwaneendlela zokugijima zeringi yokuthwala kunye neringi yangaphakathi zonakele, nto leyo ebangele ukuba ihabhu ingaphumeleli ngokupheleleyo.
Kukho iringi yokutyhala ngemagnethi ngaphakathi kwiringi yokutywina yebheringi exhotyiswe ngesixhobo se-ABS. Le ringi yokutyhala akufuneki ingqubane, itshaywe okanye idibane nezinye iindawo zemagnethi. Ngaphambi kokuba uyifake, yisuse kwibhokisi yokupakisha kwaye uyigcine kude neendawo zemagnethi, ezifana neemoto zombane okanye izixhobo zamandla ezisetyenziswayo, njl. Xa ufaka ezi bearing, jonga inaliti ye-alamu ye-ABS kwideshibhodi ngokusebenzisa uvavanyo lwemeko yendlela ukuze ulungise ukusebenza kwee bearing.
Kwii-hub bearings ezixhotyiswe ngee-ABS magnetic thrust rings, ukuze ubone ukuba i-thrust ring ifakwe kweliphi icala, ungazisa into encinci nelula kufutshane nomphetho we-bearing. Amandla emagnethi aveliswa yi-bearing aya kuyitsala. Xa uyifaka, khomba icala eline-magnetic thrust ring ngaphakathi, ujonge ngqo kwiindawo ezinobuthathaka ze-ABS. Ukufakelwa gwenxa kunokukhokelela ekungasebenzi kakuhle kwenkqubo yokuqhobosha.
Iibheringi ezininzi zivaliwe kwaye azifuni grisi ubomi bazo bonke. Ezinye iibheringi ezingavalwanga, ezifana neebheringi ezirhuqwayo ezinemigca emibini, kufuneka zithanjiswe ngegrisi ngexesha lokufakwa. Ngenxa yobukhulu obahlukeneyo bemingxuma yangaphakathi yeebheringi, kunzima ukumisela ukuba ingakanani igrisi ekufuneka yongezwe. Eyona nto ibalulekileyo kukuqinisekisa ukuba kukho igrisi kwiibheringi. Ukuba kukho igrisi eninzi kakhulu, xa iibheringi zijikeleza, igrisi engaphezulu iya kuphuma. Amava ngokubanzi: Ngexesha lokufakwa, isixa siphela segrisi kufuneka sibe yi-50% yesithuba sebheringi.
Xa kufakwa ii-lock nuts, ubukhulu be-torque buyahluka kakhulu ngenxa yokwahluka kweentlobo zeebhereyitha kunye neendawo zeebhereyitha.
Ngexesha lenkqubo yokulungisa, kudla ngokufunyaniswa ukuba ezinye izithuthi zinengxolo enkulu yokuqhuba. Emva kokujonga, akukho monakalo ungaqhelekanga kumatayara. Xa ujika amavili kwilifti, akukho ngxolo ingaqhelekanga ebonakalayo. Le meko idla ngokubangelwa kukonakala okungaqhelekanga kwi-hub bearing. Okubizwa ngokuba yi-abnormal kubhekisa kumonakalo we-bearing obangelwa zizizathu zokufakelwa. Iibheringi zamavili angaphambili zemoto zihlala ziibheringi zebhola ezimqolo emibini. Xa kufakwa iibheringi, ukuba isando sisetyenziselwa ukuzibetha okanye iringi yangaphakathi yebheringi icinezelwe xa ifakwa kwindawo yeebheringi, iya kubangela umonakalo kwindlela yokugijima kwelinye icala lebheringi. Xa imoto ishukuma, ingxolo iveliswa. Nangona kunjalo, xa amavili engekho emhlabeni, ngenxa yecala elingcono lendlela yokugijima, akukho ngxolo icacileyo inokuviwa. Ukufakelwa ngokuchanekileyo kunye nokusebenza ngundoqo kubomi obude benkonzo yeebheringi.
