Intshayelelo: Okwangoku, kushishino lweemoto kumxholo wokufakelwa kombane, ubukrelekrele kunye nokuphuculwa kwemveliso yeemoto, iimfuno zenkqubo yebrake ziyanda ngokuthe ngcembe, kwaye iidiski ze-carbon ceramic brake zineenzuzo ezicacileyo, eli nqaku liza kuthetha malunga ne-carbon ceramic brake disc. ishishini.
I. Imvelaphi yoMnyhadala
Kungekudala, i-Azera ikhuphe i-SUV yayo yokuqala enkulu ye-SUV, i-ES7, esebenzisa i-cast cast all-aluminium ngasemva kwesakhelo, okwesibini i-Azera isebenzisa iteknoloji edibeneyo yokufa kwimveliso yayo.Ngophuhliso lobunzima obukhaphukhaphu kunye nokufakelwa kombane, itekhnoloji edityanisiweyo yokulahla itekhnoloji ifunwa ngabenzi beemoto ezintsha kunye neenkampani zemoto zemveli, kwaye ukukhanya kwesakhiwo sesithuthi ngokungathandabuzekiyo kube yinxalenye yokwenziwa koyilo lwemoto yanamhlanje.Ukusetyenziswa kweediski ze-carbon ceramic brake kuya kukhuthaza ngamandla inkqubo yokukhanya kwemoto, oku kulandelayo ukuthetha ngale shishini.
Isibini, ukuqonda iidiski ze-carbon ceramic brake
Okwangoku, izixhobo zebrake ezisetyenziswa kakhulu koololiwe ababaleka ngesantya esiphezulu, iimoto kunye neenqwelomoya ubukhulu becala zingumgubo wesinyithi kunye nekhabhon-carbon composite materials.Nangona kunjalo, izixhobo ze-powder metallurgy brake zineziphene ezifana nobushushu obuphezulu bokubambisana lula, ukusebenza kwe-friction kulula ukuhla, amandla okushisa aphezulu ayancipha kakhulu, ukuxhathisa ukothuka kwe-thermal, ubomi obufutshane benkonzo, njl.ngelixa izixhobo ze-carbon carbon brake zine-static ephantsi kunye ne-wet state coefficient, umthamo omkhulu wokugcinwa kobushushu, umjikelezo omde wemveliso kunye neendleko eziphezulu zokuvelisa, ezithintela ukuphuhliswa kwayo ngakumbi kunye nokusetyenziswa.
Iidiski zeCarbon ceramic brake zidibanisa iipropathi zenyama zombini i-carbon fiber kunye ne-polycrystalline silicon carbide.Okwangoku, ubunzima bokukhanya, ubunzima obuhle, ukuzinza phantsi koxinzelelo oluphezulu kunye nobushushu obuphezulu, ukuxhathisa ukutshatyalaliswa kwe-thermal kunye neempawu zokuqhekeka kwe-shear zobunzima obufanayo abugcini nje ukwandisa ubomi benkonzo ye-disc ye-brake, kodwa kwakhona ukuphepha zonke iingxaki ezivela kumthwalo.
Okwesithathu, imeko yangoku yoshishino
1. ICarbon ceramic brake disc intsebenzo ingcono kakhulu kunesiqhelo i-grey cast iron brake disc, kodwa ixabiso ziintsilelo zayo.
Okwangoku, izinto ezisetyenziswa ngokubanzi zediskhi zebrake ziyintsimbi eqhelekileyo, intsimbi ephantsi, intsimbi eqhelekileyo, intsimbi ekhethekileyo yealloyi, intsimbi ebunjiweyo ephantsi, intsimbi ekhandiweyo kunye nentsimbi etyhidiweyo (intsimbi ekhandiweyo) izinto ezihlanganisiweyo, intsimbi. izixhobo zisetyenziswa ngokubanzi.Izinto zentsimbi yokuphosa zinomjikelo omde wokuvelisa, ukungahambi kakuhle kwe-thermal kunye nokulula ukuvelisa iintanda ze-thermal kunye nezinye iintsilelo, ngoko ke i-carbon kunye ne-carbon ceramic composite materials for development of brake materials.
Ngenxa yexabiso eliphezulu lezinto zekhabhoni zekhabhoni ezidityanisiweyo, ikakhulu ezisetyenziselwa iziqhoboshi zenqwelomoya, kunye nophuhliso lwendlela kaloliwe enesantya esiphezulu kwiminyaka yakutshanje, izazinzulu zasekhaya nezangaphandle zaqala ukuphuhlisa iindlela zikaloliwe ezinesantya esiphezulu sekhabhoni yeceramic composite vice friction. , izinto zekhabhoni ze-ceramic composite kugxininiso lwamazwe ngamazwe kuphuhliso lwezixhobo zokukhuhlana, i-China iye yaba kwinqanaba lokuqala, iidiski ze-carbon ceramic brake kwixa elizayo ukunciphisa iindleko zendawo zinkulu, kulindeleke ukuba zibe luphuhliso oluphambili lwe-brake. iimveliso Kulindeleke ukuba ibe lelona sikhokelo sophuhliso lweemveliso zebrake.
2. Ixabiso lezinto eziphathekayo ze-carbon ceramic ceramic discs zincinci, kwaye kukho indawo enkulu yokunciphisa iindleko kwi-teknoloji kunye nesikali.
Ngo-2021, ixabiso letoni enye yeemveliso ezishushu zenkampani yi-370,000 yuan/toni, yehle nge-20% ukusuka kwi-460,000 yeyuan/toni ngo-2017, kwaye iindleko zokwenziwa kwetoni enye yi-11.4 yezigidi zeeyuan ngo-2021, zehle nge-53.8% ukusuka kwi-53.8%. 246,800 yuan ngo-2017, nto leyo ebalulekileyo yokunciphisa iindleko zobugcisa.Ngo-2021, umlinganiselo weendleko zempahla ekrwada ngama-52%.Ngokwandiswa kwesikali, ukuphuculwa kwetekhnoloji, ukuphuculwa kwenqanaba le-automation kunye nokuhla kwexabiso le-carbon fiber, kukho indawo enkulu yokunciphisa iindleko zemveliso.Ixabiso langoku lekhabhoni ye-ceramic brake pad limalunga ne-2500-3500 yuan, kuba ngodidi lwe-C nangaphezulu kwemarike yemoto yabahambi, kulindeleke ukuba ngo-2025 ixabiso leqhekeza elinye kulindeleke ukuba lehle liye malunga ne-1000-1200 yuan, liya kuba phantsi. ukuya kudidi B nangaphezulu kwimarike yeemoto zabahambi.
Isine, amathemba oshishino
1. Iidiski zeCarbon ceramic brake zinendawo eninzi yokutshintshwa kwasekhaya
Ngenxa yobunzima benkqubo, ubunzima bemveliso, umjikelezo wemveliso omde kunye neminye imida, amashishini asekhaya anokuvelisa i-carbon ceramic discs zimbalwa.Ababoneleli abaphambili bekhabhoni ceramic composite discs brake discs baquka iBrembo (Italiya), iSurface Transforms Plc (UK), iFusionbrakes (USA), njl.njl. Amashishini asekhaya ambalwa afumene itekhnoloji yokulungiselela ukusebenza okuphezulu kwekhabhoni/tau composite brake discs, kwaye apho. yindawo enkulu yokutshintsha ikhaya.
Abathengi abaphambili baphesheya kwekhabhoni ye-ceramic brake disc abavelisi ngabavelisi bemoto bezemidlalo abaphezulu, kwaye ixabiso leyunithi yeemveliso liphezulu.Thatha inkampani yaphesheya iBrembo njengomzekelo, ixabiso lemveliso ye-disc ye-carbon ceramic disc ingaphezulu kwe-100,000 RMB, ngelixa ixabiso le-disc ye-carbon ceramic yasekhaya malunga ne-0.8-12,000 RMB, enexabiso eliphezulu kakhulu lokusebenza.Ngokuqhubekayo kwetheknoloji yokuphumelela kwamashishini asekhaya kule ntsimi, kunye nenguqu eqhubekayo yendlela "yongezelelweyo, ephezulu, ehlakaniphile" izithuthi zamandla amatsha, izinga lokungena kwe-carbon ceramic discs kwizithuthi zamandla amatsha asekhaya kulindeleke ukuba ziqhubeke zikhula.
2. Iidiski zeCarbon ceramic brake discs zidibana nendlela yokukhanya kwemoto
Ubungqina bovavanyo bubonisa ukuba ukucutha ubunzima besithuthi nge-10% kunokunyusa ukusebenza kakuhle kwamafutha nge-6% - -8%;kwi-100 kg nganye yokunciphisa ubunzima besithuthi, ukusetyenziswa kwamafutha kungancitshiswa nge-0.3 - -0.6 iilitha nge-100 km, ngoko ke iteknoloji ekhaphukhaphu yeyona ndlela yokuphuhlisa izithuthi ezizayo.
Ukunciphisa ubunzima ngaphantsi kwenkqubo yokunqunyanyiswa kunye nesiqingatha somzamo, i-carbon ceramic brake disc iyona nxalenye ephambili yokunciphisa ubunzima.Yonke i-1kg yokunciphisa ngaphantsi kwenkqubo yokunqunyanyiswa ilingana nokunciphisa i-5kg ngaphezu kwenkqubo yokunqunyanyiswa.Iperi ye-380mm ubukhulu beediski ze-carbon ceramic malunga ne-20kg lighter kune-gray cast iron discs, elingana nokunciphisa ubunzima be-100kg kwinkqubo yokumiswa kwemoto.Ukongeza, imoto yezemidlalo ephezulu yeToyota Lexus RCF iye yadlula kwi-CFRP kunye ne-carbon ceramic brake discs ukunciphisa ubunzima be-70kg kwimiba emininzi, apho i-22kg inegalelo kwiidiski ze-carbon ceramic brake discs, ngoko ke iidiski ze-carbon ceramic brake disc iindawo eziphambili zokunciphisa ubunzima bemoto.
V. Indawo yeMarike
Ukutshintsha i-disc ye-powder metallurgy brake ye-original yindlela engenakuthintelwa yolu shishino: okokuqala, ixabiso le-carbon fiber liya kuncipha ngokuthe ngcembe ukuqhuba iindleko ezithe ngqo zemveliso ngokwayo;okwesibini, ngokunyuka kwemveliso kunye nokuthengisa isikali, ukulungiswa kwekhonkco yenkqubo, uqoqosho lwesikali luya kuthoba iindleko ze-carbon ceramic brake disc;okwesithathu, amava okuqhuba ngokukhuselekileyo aya kukhuthaza ukuphuculwa kweemveliso kushishino lweemoto.Ngo-2023 kulindeleke ukuba ibe ngunyaka wokuqala wokukhuthazwa kwe-carbon ceramic brake disc.Unyaka wokuqala wokunyuswa kwe-brake disc, imarike yasekhaya kulindeleke ukuba ifikelele kwi-7.8 yeebhiliyoni zeeyuan ngo-2025, kwaye ubungakanani bemarike yasekhaya kulindeleke ukuba budlule kwi-20 yeebhiliyoni zeeyuan ngo-2030.
Ngo-2025, ubungakanani bemalike yeediski ze-metallurgy brake discs buya kuba yi-90 yeebhiliyoni zeeyuan ngokwexabiso le-yuan eli-1000 ngemoto enye kunye ne-90 yezigidi zeemoto ezithengiswa kwihlabathi jikelele, kwaye imarike yasekhaya iya kuba kufuphi ne-30 yeebhiliyoni zeeyuan.Ngokukhawuleziswa kokufakelwa kombane, izinga lokungena kweediski ze-carbon ceramic brake discs ngokuqinisekileyo liya kudlula besilindele.Le yimarike entsha kraca ehambelana nentsingiselo eqhelekileyo yophuhliso lobukrelekrele bombane kwaye yimpumelelo ye-0-1.Kwaye kuqwalaselo lokhuseleko lweemoto, xa ukuphumelela kuya kuba yindawo yokuthengisa ukhuseleko lweemoto, izinga lophuhliso lilindeleke ukuba ligqithise okulindelekileyo, kwaye ikamva elipheleleyo lokuthengisa ingeniso yemarike iya kulindeleka ukuba isondele kwi-200-300 yebhiliyoni ye-yuan.
