Iyiphi impahla esetshenziswa yisondo langemuva lemoto?
Izinto ezisetshenziswa kuma-bearing amasondo angemuva ezimoto ngokuvamile ziyinsimbi ethwala i-chromium enekhabhoni ephezulu (njenge-GCr15), enobulukhuni obuphezulu (58-65HRC) kanye nokumelana okuhle nokuguguleka, futhi ifaneleka ekukhiqizweni kwama-bearing amasondo angemuva ezimoto endabuko.
Ukukhethwa kwezinto ngaphansi kwezimo zokusebenza ezikhethekile
Ezindaweni ezinokushisa okuphezulu noma ezigqwalisayo, izinto ezilandelayo ezikhethekile zingasetshenziswa:
Izimo zokusebenza ze-Youdaoplaceholder0 Eziphezulu: Uma izinga lokushisa lidlula u-180℃, kufanele kusetshenziswe ama-alloy asekelwe ku-cobalt, ama-alloy asekelwe ku-chromium noma ama-alloy asekelwe ku-molybdenum.
I-Youdaoplaceholder0 Indawo egqwalisayo : Sebenzisa insimbi engagqwali ye-martensitic (emelana nokugqwala futhi enobunzima obuphezulu) noma insimbi engagqwali ye-austenitic (emelana nokugqwala okungcono).
Inqubo yokukhiqiza yendabuko
Ama-wheel bearings angemuva ezimoto zendabuko asebenzisa kakhulu isakhiwo esihlanganisiwe sama-roller bearings anemigqa emibili noma ama-ball bearings. Ukufakwa kwawo, ukufakwa kwamafutha, ukuvalwa kanye nokulungiswa kokususwa kwawo konke kuqedwa emgqeni wokukhiqiza izimoto.
Indandatho yokuvala esebenza kahle kakhulu
Ngenxa yokuthi ama-hub bearing aseduze kakhulu nomhlabathi kanye nezingxenye ezifana nama-brake disc anamazinga okushisa aphezulu, adinga ukuzivumelanisa nezimo zomgwaqo ezahlukahlukene eziyinkimbinkimbi kanye nezimo zokushayela ezinzima. Ngakho-ke, indandatho yokuvala ama-bearing kumele ibe nokusebenza okuhle kakhulu kokuvimbela ukuvuza kwamafutha, futhi ngesikhathi esifanayo, kumele futhi ibe nokumelana okuhle nokushisa, ukusebenza kahle kokuvimbela udaka kanye nendle.
Ubuchwepheshe bokugoqa
Ama-hub bearings esizukulwane sesithathu ngokuvamile asebenzisa ubuchwepheshe bokugoqa ukuze azikhiyele indandatho yangaphakathi eyingxenye. Uma kusetshenziswa ubuchwepheshe bokugoqa, umthwalo we-axial ubangela ukuguqulwa kwepulasitiki ekugcineni kwe-hub main shaft, ngaleyo ndlela uxhumanisa i-hub main shaft kanye ne-half inner ring njengento eyodwa. Uma kuqhathaniswa nokubopha kwendabuko kwe-nut, i-hub bearings yesizukulwane sesithathu esebenzisa ubuchwepheshe bokugoqa isiza ukunciphisa ivolumu nesisindo, ukwehlisa izindleko, kanye nokuthuthukisa ukuthembeka kwe-hub bearings. Ngesikhathi esifanayo, lapho uyihlanganisa emotweni, isinyathelo sokulungisa izikhundla zezingxenye zangaphakathi siyasuswa.
Ilula futhi incane
Uma kuklanywa isakhiwo sama-hub bearings esizukulwane sesibili nesesithathu, ukuhlaziywa kwezinto ezilinganiselwe kumele kwenziwe ukuqinisekisa ukuthi i-flange inokuqina okwanele ngenkathi kunciphisa ivolumu nesisindo sayo ngangokunokwenzeka. Phakathi kwazo, ukuqina kwe-hub bearings yesizukulwane sesithathu kubhekisela ekuthambekeni kwe-Angle ye-hub flange maqondana ne-flange yangaphandle yendandatho. Isisindo se-axle sincishiswa ngomklamo ohlanganisiwe nowenziwe kancane. I-hub bearings yesizukulwane sesibili ilula ngo-180g kunesizukulwane sokuqala, kanti i-hub bearings yesizukulwane sesithathu inciphisa isisindo ngo-120g.
I-torque ephansi yokungqubuzana
Isinyathelo esibalulekile sokunciphisa ukusetshenziswa kukaphethiloli kwezimoto ukuklama ama-hub bearings ane-torque ephansi yokushayisana. Izici eziyinhloko ezithinta i-torque yokushayisana kwama-bearings uhlobo lwama-bearings kanye nokulayisha kwangaphambili. Ukuvalwa kwama-bearings kubala ingxenye enkulu yezingxenye ze-torque yokushayisana. Ngakho-ke, ukuthuthukisa ukwakheka kokuvala ukuze kuncishiswe i-torque yokushayisana kungathuthukisa kakhulu ukusebenza kwama-hub bearings. Ama-hub bearings ashintshe kusukela esizukulwaneni sokuqala kuya esizukulwaneni sesine sakamuva, kanti i-torque yokushayisana yehla kakhulu futhi kancane kancane.
Ubuchwepheshe be-ABS
I-ABS iyithuluzi lokulawula ukuphepha kwezimoto elinezinzuzo ezifana nokungasheleli kanye nokungakhiyi. Uma imoto ibhuleka ngokuzumayo, ilungisa ngokuzenzakalelayo amandla okubhuleka ngokuthola isivinini sesondo ukuvimbela amasondo ukuthi angavaleki futhi ifinyeze ibanga lokubhuleka. Ukutholwa kwesivinini sokujikeleza kwenziwa yizinzwa zamagnetic ezifakwe ezingxenyeni ezijikeleza namasondo futhi eziseduze zinamathele emzimbeni wemoto. Kunezinhlobo ezimbili zamayunithi ehabhu anezinzwa ze-ABS: eyodwa ifakwa ngaphakathi kwehabhu, kuyilapho izinzwa zifakwe kwezinye izingxenye; Olunye uhlobo lufakwa ngaphakathi kwehabhu kanye nenzwa (ebizwa ngokuthi iyunithi yehabhu enenzwa).
Ama-hub bearings noma ama-hub units agugile noma alimele angabangela ukwehluleka okungafanele nokubizayo kwemoto yakho ngesikhathi sokushayela, futhi angaba yingozi ngisho nasekuphepheni kwakho. Sicela uqaphele izinto ezilandelayo uma usebenzisa futhi ufaka ama-hub bearings:
Ukuze kuqinisekiswe ukuphepha nokuthembeka ngezinga elikhulu, kunconywa ukuthi uhlole njalo ama-hub bearings kungakhathaliseki ukuthi imoto ineminyaka emingaki - qaphela izimpawu zokuxwayisa zakuqala zokuguga kwama-bearings: kufaka phakathi noma yimuphi umsindo wokungqubuzana ngesikhathi sokujikeleza noma ukwehla okungavamile kwamasondo okuhlanganiswa kokumiswa lapho ujika.
Ezimotweni ezishayela ngemuva, kunconywa ukuthi ama-front hub bearing agcotshwe uma imoto isihambe amakhilomitha angu-38,000. Uma ushintsha uhlelo lokubhuleka, hlola ama-bearing bese ushintsha izivalo zikawoyela.
Uma uzwa umsindo ongajwayelekile uvela endaweni ye-hub bearing, into yokuqala nebaluleke kakhulu ukuthola indawo lapho umsindo uvela khona. Kunezingxenye eziningi ezihambayo ezingase zikhiqize umsindo, noma kungenzeka ukuthi ezinye izingxenye ezijikelezayo zithintene nezingxenye ezingajikelezi. Uma kuqinisekiswa ukuthi umsindo uvela ku-bearing, i-bearing ingase yonakale futhi idinga ukushintshwa.
Ngenxa yokuthi izimo zokusebenza ezibangela ukwehluleka kwama-bearings ezinhlangothini zombili ngenxa yehabhu yesondo langaphambili ziyafana, kunconywa ukuthi uwashintshe ngamabili noma ngabe i-bearings eyodwa kuphela yonakele.
Ama-Hub bearing ayazwela kakhulu, futhi noma kunjalo, izindlela ezifanele namathuluzi afanele kumele asetshenziswe. Ngesikhathi sokugcina, ukuthuthwa nokufakwa, izingxenye ze-bearing akumele zonakaliswe. Amanye ama-bearing adinga ingcindezi enkulu ukuze acindezelwe, ngakho-ke kudingeka amathuluzi akhethekile. Qiniseka ukuthi ubheka incwadi yemiyalelo yokukhiqiza izimoto.
Uma ufaka ama-bearings, kufanele enziwe endaweni ehlanzekile nehlelekile. Izinhlayiya ezincane ezingena kuma-bearings nazo zizofinyeza isikhathi sazo sokusebenza. Kubaluleke kakhulu ukugcina indawo ihlanzekile lapho ushintsha ama-bearings. Akuvunyelwe ukushaya i-bearings ngesando. Qaphela ukuthi ungayiwisi i-bearings phansi (noma ungayiphathi ngendlela efanayo). Ngaphambi kokufakwa, isimo se-shaft kanye ne-bearings kufanele sihlolwe. Ngisho nokuguguleka okuncane kungaholela ekungalingani kahle, ngaleyo ndlela kubangele ukwehluleka kwe-bearings ngaphambi kwesikhathi.
Kumayunithi okuthwala ihabhu, ungazami ukuqaqa ama-hub bearings noma ukulungisa amasongo okuvala amayunithi ehabhu; ngaphandle kwalokho, amasongo okuvala angase onakale, okuvumela amanzi noma uthuli ukuthi kungene. Ngisho nemigwaqo yokugijima yendandatho yokuvala kanye nendandatho yangaphakathi yonakele, okwaholela ekuhlulekeni unomphela kwebheyaringi.
Kukhona indandatho yokuphoqa enozibuthe ngaphakathi kwendandatho yokuvala yebheri efakwe idivayisi ye-ABS. Le ndandatho yokuphoqa akumele ishayisane, ishayisane noma ithintane nezinye izinkundla zikazibuthe. Ngaphambi kokufaka, zisuse ebhokisini lokupakisha bese uzigcina kude nezinkundla zikazibuthe, njengezinjini zikagesi noma amathuluzi kagesi asetshenziswayo, njll. Uma ufaka la mabheringi, qaphela inaliti ye-alamu ye-ABS kudeshibhodi ngokusebenzisa izivivinyo zesimo somgwaqo ukuze ulungise ukusebenza kwamabheringi.
Kuma-hub bearing afakwe izindandatho ze-ABS magnetic thrust, ukuze unqume ukuthi indandatho ye-thrust ifakwe kuluphi uhlangothi, ungaletha into encane nelula eduze komphetho we-bearing. Amandla kazibuthe akhiqizwa yi-bearing azoyidonsela. Uma uyifaka, khomba uhlangothi olunendandatho ye-magnetic thrust ngaphakathi, ubheke ngqo izingxenye ezibucayi ze-ABS. Ukufakwa okungalungile kungaholela ekungasebenzi kahle komsebenzi wesistimu yokubhuleka.
Ama-bearing amaningi avalwe futhi awadingi amafutha kuyo yonke impilo yawo yokusebenza. Amanye ama-bearing angavaliwe, njenge-double-row tapered roller bearing, kumele agcotshwe amafutha ngesikhathi sokufakwa. Ngenxa yobukhulu obuhlukene bezikhala zangaphakathi zama-bearing, kunzima ukunquma ukuthi kufanele kufakwe amafutha angakanani. Into ebaluleke kakhulu ukuqinisekisa ukuthi kukhona amafutha kuma-bearing. Uma kukhona amafutha amaningi kakhulu, lapho ama-bearing ejikeleza, amafutha amaningi azophuma. Okuhlangenwe nakho okuvamile: Ngesikhathi sokufakwa, inani eliphelele lamafutha kufanele libe ngu-50% wesikhala se-bearing.
Uma ufaka ama-lock nuts, ubukhulu be-torque buyahlukahluka kakhulu ngenxa yokwehluka kwezinhlobo zama-bearing kanye nezindawo zokubeka ama-bearing. Sicela ubheke imiyalelo efanele.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
