Udindo waukulu wa disc ya brake yakutsogolo mu dongosolo la brake yamagalimoto
Mu dongosolo la mabuleki a magalimoto, diski ya mabuleki akutsogolo ndi imodzi mwa zinthu zofunika kwambiri zomwe zimaonetsetsa kuti kuyendetsa kuli kotetezeka, ndipo imakhala ndi mphamvu zambiri zomangira kuposa diski ya mabuleki akumbuyo. Malinga ndi kuwerengera, panthawi yomangira galimoto, diski ya mabuleki akutsogolo iyenera kukhala ndi mphamvu ya mabuleki ya 70%-80%. Izi zimachitika chifukwa cha mawonekedwe akuthupi omwe pakati pa mphamvu yokoka ya galimoto imasunthira patsogolo panthawi yomangira - kulemera kwa gawo lakutsogolo la galimoto kumawonjezeka mwadzidzidzi kufika pafupifupi 70% ya kulemera konse kwa galimotoyo. Disk ya mabuleki akutsogolo iyenera kusintha mphamvu ya kinetic ya galimoto kukhala mphamvu yotentha kudzera mukukangana kwamphamvu kwambiri ndi mabuleki, zomwe zimapangitsa kuti liwiro lichepe kapena kuyima mwachangu.
Ntchito ya disc ya brake yakutsogolo sikutanthauza "kuchepetsa mphamvu" yokha; komanso ndiyo chonyamulira chofunikira kwambiri pakugwira ntchito bwino kwa system ya brake. Ndi nsanja yayikulu yosinthira mphamvu ya kinetic, ndikupanga kutentha kudzera mukukangana kuti idye mphamvu ya galimoto; nthawi yomweyo, ma disc ambiri a brake akutsogolo amagwiritsa ntchito kapangidwe ka disc yopumira mpweya, yokhala ndi kapangidwe kopanda kanthu komwe kangafulumizitse kugwedezeka kwa mpweya ndikuchotsa mwachangu kutentha kwa 500-700℃ komwe kumapangidwa ndi kukangana, kupewa kulephera kwa brake komwe kumachitika chifukwa cha kuchepa kwa kutentha; kuphatikiza apo, ndi malo ogwiritsira ntchito makina othandizira zamagetsi monga ABS, ogwirizana ndi masensa kuti asinthe mphamvu ya brake nthawi yeniyeni kuti atsimikizire kuti mawilo sakutseka panthawi ya brake yadzidzidzi ndikusunga bata la kuwongolera galimoto.
Poyerekeza ndi diski ya mabuleki akumbuyo, kapangidwe ka diski ya mabuleki akutsogolo kamayang'ana kwambiri kusintha magwiridwe antchito. Nthawi zambiri, m'mimba mwake mwa diski ya mabuleki akutsogolo ndi yayikulu, monga diski ya mabuleki akutsogolo ya Corolla yokhala ndi m'mimba mwake wa 287mm, pomwe diski yakumbuyo ndi 255mm yokha. Malo akuluakulu okangana amatha kupereka mphamvu yowonjezereka yoletsa mabuleki; zinthuzo nthawi zambiri zimagwiritsa ntchito chitsulo chakuda cha HT200 kapena HT250, ndipo mitundu ina yapamwamba imagwiritsa ntchito chitsulo cha alloy cast kuti itsimikizire mphamvu zokwanira komanso kukana kuwonongeka pa kutentha kwambiri komanso kupsinjika kwakukulu; kapangidwe kake, ma diski ambiri akutsogolo amakhala ndi ma caliper awiri a piston, omwe amatha kugwiritsa ntchito mphamvu yoletsa mabuleki mofanana komanso kusinthana ndi zochitika zobwerezabwereza monga kuyenda m'mizinda komanso kuyendetsa mapiri.
Zolakwika zomwe zimachitika kawirikawiri komanso zomwe zimayambitsa diski yakutsogolo ya brake
Kugwedezeka kwa mabuleki ndi phokoso losazolowereka
Ichi ndi chizindikiro chofala kwambiri cha diski ya brake yakutsogolo, makamaka chifukwa cha kupotoka kwa planearity ya pamwamba pa disc. Malinga ndi miyezo yamakampani, pamene cholakwika cha planearity cha pamwamba pa ntchito ya brake disc chikuposa 0.05mm, malo olumikizirana pakati pa brake pad ndi pamwamba pa disc amasintha nthawi ndi nthawi ndi kuzungulira kwa diski, zomwe zimapangitsa kusinthasintha kwa torque ya brake, kenako kuyambitsa kugwedezeka kwa chiwongolero ndi kugwedezeka kwa thupi. Kutseka kwadzidzidzi pafupipafupi ndi chimodzi mwa zifukwa zazikulu. Panthawi yotseka, kutentha kwa pamwamba pa disc kumakwera kufika pa 600℃, ndipo pamwamba pa diski pamakhala kutentha kwambiri; kuwonongeka kwa nthawi yayitali kwa ma grooves, masitepe, kapena kulimbitsa torque molakwika panthawi yoyika kungapangitsenso kupotoka kwa planearity.
Zomwe zimayambitsa phokoso losazolowereka ndi zosiyanasiyana: dzimbiri kapena kusonkhana kwa dothi pamwamba pa diski ya brake, ikakhudza brake pad, imapanga phokoso lakuthwa lachitsulo lokanda; brake pad ikatopa kwambiri, mbale yakumbuyo yachitsulo imakhudzana mwachindunji ndi diski, ndikutulutsa phokoso losazolowereka; kuphatikiza apo, ma brake disc ndi ma hub screws osasunthika, kapena kusintha kosazolowereka kwa dongosolo la brake, zomwe zimapangitsa kuti mtunda wa brake pad ndi pamwamba pa diski ukhale wosiyana, zingayambitsenso phokoso losazolowereka nthawi ndi nthawi.
Kuwonongeka kwa kutentha ndi kuchepa kwa magwiridwe antchito
Pa nthawi yoyendetsa galimoto yotsika phiri kapena nthawi zambiri yochita mabuleki adzidzidzi, diski ya brake yakutsogolo imakhalabe mu kutentha kwambiri kwa nthawi yayitali. Ngati kutentha sikunayende bwino, kutentha kudzachepa - mphamvu ya brake imachepa kwambiri, pedal ya brake imakhala yofewa, ndipo mtunda wa brake umatalikitsidwa. Izi zili choncho chifukwa chakuti coefficient ya friction ya brake disc imachepa kutentha kwambiri, ndipo pamwamba pa diski pakhoza kukhala ming'alu ya kutentha, zomwe zimapangitsa kuti mabuleki asamayende bwino. Kutsekeka kwa diski yopumira kapena chinyezi chochuluka mu brake fluid (kupitirira 3%) zomwe zimapangitsa kuti kutentha kuchepe ndizomwe zimayambitsa kutentha.
Kuwonongeka kwambiri komanso makulidwe osakwanira
Nthawi yogwiritsidwa ntchito bwino ya disc ya brake yakutsogolo ndi pafupifupi makilomita 8-120,000, koma kuletsa mabuleki pafupipafupi, kuyendetsa galimoto nthawi yayitali mumsewu wodzaza magalimoto, ndi zizolowezi zina zoyipa zoyendetsera galimoto zidzafupikitsa kwambiri nthawi yake yogwirira ntchito. Pamene makulidwe a disc ya brake atha kufika pa 1/3 ya makulidwe oyamba (nthawi zambiri makulidwe oyamba ndi 22-30mm, ndipo amafunika kukhala maso akatha kufika pa 22mm), mphamvu yake idzachepa kwambiri, osati kungochepetsa mphamvu ya mabuleki komanso kusweka panthawi ya mabuleki, zomwe zimayambitsa ngozi zazikulu zachitetezo. Kuphatikiza apo, ngati zinthu za brake pad zili zolimba kwambiri ndipo pali zinthu zakunja zosakanikirana, zidzafulumizitsa kuwonongeka kwa disc ya brake, ndikupanga mizere yozama.
Kuzindikira zolakwika ndi malingaliro osamalira tsiku ndi tsiku
Pothana ndi vuto la brake disc yakutsogolo, chinthu choyamba chiyenera kutsatiridwa pothetsa mavuto: Choyamba, yang'anani momwe diski ilili ndikuyesa kuphwanyika pogwiritsa ntchito chizindikiro choyimbira. Ngati kupotoka kukupitirira muyezo, gawo la pamwamba la 0.5-1mm likhoza kuchotsedwa pogwiritsa ntchito disc disc (kuti abwezeretse kuphwanyika), ndipo ngati kuphwanyika kuli kwakukulu, kusinthidwa ndikofunikira; chachiwiri, yang'anani makulidwe a brake pad. Ngati makulidwe otsalawo ndi ochepera 3mm, kusinthidwa ndikofunikira. Nthawi yomweyo, onetsetsani kuti zinthu za brake pad zikugwirizana ndi za brake disc; pomaliza, yang'anani momwe brake system ilili. Nthawi zonse sinthani brake fluid (zaka ziwiri zilizonse kapena makilomita 40,000), kuonetsetsa kuti chinyezi chili pansi pa 3%, ndikutulutsa mpweya m'dongosolo.
Pakukonza tsiku ndi tsiku, pewani kutsuka galimoto mwachindunji pamene brake disc ili yotentha kuti mupewe kusintha kwa ma disc chifukwa cha kutentha kozizira; yang'anani makulidwe ndi kusalala kwa brake disc kamodzi pa makilomita 30,000 aliwonse, ndikukonza bwino dynamic balance ya tayala kamodzi pa makilomita 10,000 aliwonse kuti mupewe kusalingana kwa tayala kuwonjezere mphamvu ya braking; khalani ndi zizolowezi zabwino zoyendetsera galimoto, muchepetse braking yadzidzidzi pafupipafupi, ndipo gwiritsani ntchito braking ya injini kuti muchepetse mphamvu ya brake disc panthawi yayitali kuti muchepetse ntchito ya brake disc yakutsogolo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
