Zokwera mtengo, koma kwamuyaya: ma disc a ceramic brake

Chombo cholowa mumlengalenga cha Dziko Lapansi chimakumana ndi mpweya wovuta kwambiri. Ndicho chifukwa chake makapisozi amlengalenga ndi ma shuttles ali ndi chitetezo chotentha chomwe chimatha kupirira kutentha kwakukulu. Ma matailosi a ceramic awa apeza njira yawo yogulitsira magalimoto ngati ma brake discs. Kupatula apo, ma brake system amakhudzidwa kwambiri ndi kutentha kwakukulu chifukwa chakukangana.

Kodi mabuleki a ceramic ndi chiyani?

Kumva mawu " keramiki ”, mungaganize za zoumba. Zowonadi , zigawo za ceramic ndizofunikira kwambiri pamakampani. Iwo makamaka mphamvu yotchinga kwambiri polimbana ndi mafunde amagetsi ndi kutentha kumawapangitsa kukhala chinthu choyenera kumadera ovuta kwambiri .

Mabuleki amagwiritsa ntchito zida zapadera za ceramic: Zomwe zimapangidwa ndi kaboni fiber ndi silicon carbide ndizosakanikirana bwino kuti zizitha kuyamwa mphamvu zothamanga kwambiri.

Chifukwa chake, mabuleki a ceramic ali ndi gawo limodzi kapena zingapo zopangidwa ndi izi, yomwe ili ndi ubwino ndi kuipa kwake .

Zabwino motsutsana ndi zotsatira zakuzirala

Mabuleki agalimoto amagwira ntchito mogundana. . Chonyamulira choyima chokhala ndi lining chimakanikizidwa motsutsana ndi chinthu chozungulira, ndikupanga mphamvu yothamanga, motero kuchepetsa mphamvu yoyenda. Kukangana kumatulutsa kutentha kwakukulu, zomwe zingakhale zovuta.
Kutentha kwa mkangano kukafika pamalo osungunuka a chinthu chozungulira, mwachitsanzo disk kapena ng'oma , mphamvu ya braking imachepetsedwa . M'ng'oma zamabuleki zomwe zidatha kale, izi nthawi zina zidapangitsa kuti alephere.

Apa ndipamene ma disc a ceramic brake amapereka yankho. . Zomangamanga zawo zimakhala ndi malo osungunuka kwambiri omwe safika ngakhale pansi pa zovuta zoyendetsa galimoto. Mpweya ceramic brake zimbale si kuwala ndi otetezeka ; ndi ntchito yachibadwa, amakhala mpaka kalekale. Nthawi utumiki mpaka 350 Km ndiye muyezo wa zinthu izi.

Chifukwa cha zinthu zakuthupi, imvi kuponyedwa zitsulo brake zimbale atenge dzimbiri. . Ma modules awa amadalira kwambiri kudziyeretsa kwawo pansi pamayendedwe oyendetsa bwino.

Monga zinthu zopanda zitsulo, carbon-ceramic composite imatetezedwa ku mchere ndi dzimbiri. . Kusakhalapo kwa dzimbiri komanso kuwonongeka kwa dzimbiri panthawi ya braking ndi chinthu chofunikira kwambiri pakukaniza ma disc a carbon-ceramic brake disc.

Vuto lalikulu: kutaya kutentha

Kutentha kopangidwa ndi ma diski a carbon-ceramic brake sikumatengedwanso ndipo chifukwa chake zigawo zozungulira zimawonekera kutentha. . Chifukwa cha kutentha kwapang'onopang'ono, ma hoses ophwanyidwa ndi zingwe za sensor ziyenera kutetezedwa ndi ceramic fiber insulation.

Kuchepetsa kutentha kwayesedwa mu ma modules mpaka 1600 ° C. Ma disc a Ceramic brake amafunikira ma brake pads ofanana. Chifukwa chake, m'malo mwa ma brake disc ndizovuta kwambiri kuposa momwe anthu ambiri amakhulupilira.

Palibe malonda panobe

Gray cast steel brake discs amapangidwa ndi jakisoni ndikuwumbidwa mpaka kukula . Chilichonse chikalakwika, chimbale cha brake chimangosungunuka ndikusinthidwanso. Palibe chilichonse chotayika munjira iyi yopanga.

Komano, ma disks osokonekera a carbon-ceramic brake discs sangathe kusungunuka. . Zitha kuphwanyidwa ndikugwiritsidwa ntchito ngati chowonjezera pamakampani omanga. Komabe, zobwezereranso zotsika mtengo zotsalira ndi zotsalira, zomwe zimapezeka pakupanga zitsulo, sizigwira ntchito pano. .

Ichi ndi chimodzi mwa zifukwa carbon ceramic brake discs ndi okwera mtengo kwambiri . Poyerekeza: makina a brake a ceramic amatha kuwononga ndalama zokwana €10 (±£000) . Silipira ngakhale magalimoto apabanja apamwamba. Ndiye makonda okhazikika zosungidwira ma limousine, magalimoto amasewera, magalimoto othamanga akatswiri, ma vans a CIT и magalimoto okhala ndi zida .

Komabe, kusuntha kwamagetsi kumatha kuyambitsa kukhazikitsidwa wamba . Kuphatikiza pakuchita bwino kwa braking komanso kukhazikika kwapadera, mabuleki a carbon ceramic ndi opepuka kwambiri . M'galimoto yamagetsi, ma ounces aliwonse omwe amasungidwa nthawi yomweyo amakhudza mtundu wake. Choncho, ma disks a carbon-ceramic brake angathandize kuchepetsa kulemera. Komabe, izi zikadali patali.

Kugwiritsa ntchito bwino kwa ceramic

Komabe ntchito zida za ceramic m'magalimoto okhazikika ndizoyenera . M'malo mosintha mawilo achitsulo ndi zida za carbon-ceramic, njira yokwanira ndiye kukhazikitsa ma brake pads a ceramic.

Ceramic brake pads amapezeka kuchokera kwa opanga odziwika ngati chowonjezera . Amayikidwa mofanana ndi ma brake pads achikhalidwe. Kugwiritsa ntchito kwawo kumapereka zabwino zingapo:

- kuwonjezeka kukana kuvala - zochepa abrasion - kuchepetsa phokoso - kugwira bwino ndi chonyowa brake chimbale

Kuchita kwa braking Mabomba a Ceramic amatha kufananizidwa ndi mapepala achikhalidwe. Chimbalangondo mu malingaliro ngati galimoto yanu ili ndi marimu okongola, mukudzichitira nokha zabwino pogwiritsa ntchito ma brake pads . Abrasion yowopsya imakonda kusiya fumbi louma lomwe ndi lovuta kuchotsa. Ma brake pads a Ceramic amachititsa kuti abrake achepetse kwambiri.

Zodabwitsa kwambiri zida zotsika mtengo zokhala ndi zomangira za ceramic. Opanga odziwika amapereka mitengo yanjira iyi yomwe siyiposa mitengo yama brake kits: zida za ATE, kuphatikiza ma brake disc, linings ndi zina zowonjezera, mtengo wa pafupifupi. €130 (± £115) .

Izi sizikuchulukirachulukira kwa chinthu chamtundu wa OEM kuchokera kwa ogulitsa odziwika. . Mitengo yotsika iyi imapangitsa kukhala koyenera kusankha izi pokonza mabuleki otsatirawa.

Nthawi zonse sankhani zatsopano

Kupanga ma brake discs kumapitilira kugwiritsa ntchito zoumba. Kukula kwaposachedwa ndi ma hybrid drives: Chimbale chachikhalidwe cha imvi chachitsulo chophwanyidwa ndi chotengera cha aluminiyamu . Kumene kumavala kwapamwamba ndi kutenthetsa kutentha kumafunika, ma hybrid brake discs amapereka ntchito yonse.

Mawu oti "misa" ali apa: zosavuta single ananyema zimbale pafupifupi konse ntchito masiku ano . Wapawiri mpweya mabuleki zimbale tsopano muyezo pa chitsulo chogwira ntchito kutsogolo.
Mwatsoka, mapindu ambiri zoperekedwa ndi zida zatsopanozi monga kutulutsa bwino kwa kutentha ndi ntchito , pita limodzi ndi misa yowonjezeredwa.

Komabe, izi zitha kuchepetsedwa muzinthu zina: kumene zitsulo zolemera zimawonjezera kulemera kwa galimoto, ma hybrid brake discs amakhala ndi aluminiyumu yopepuka . Gawo lolumikizana pakati pa mphete ya brake ndi gudumu la gudumu limapangidwa chitsulo chopepuka mu ma disks ochita bwino kwambiri .

Inde, izi ndizochepa chabe zothandizira kuchepetsa thupi. . Komabe, popeza ma brake discs ndizovuta kwambiri zosuntha, kuchepetsa kulikonse ndikovomerezeka. Diski yopepuka ya brake imapangitsa kusalinganika pang'ono ndikusunga makina owongolera owongolera.

Palibe kusiyana mu khalidwe mphamvu ya aluminiyamu mu aloyi yolondola tsopano ingayerekezedwe ndi chitsulo .

Chifukwa chiyani rimu yonseyo si aluminiyamu?

Kupanga ma brake disc onse kuchokera ku aluminiyamu zosatheka pazifukwa ziwiri:

- malo osungunuka otsika - osalimba mokwanira

aluminiyamu amasungunuka pa 600°C . Standard braking amayendetsa mosavuta amatsogolera kutentha pamwamba pa 1000 ° C , ndipo kotero chitsulo chopepuka chidzalephera pambuyo poyesera pang'ono braking.

Ndipo kuposa izo: aluminiyamu imatha kuphulika. Kuvala sikuvomerezeka ngakhale ndi braking mosamala. Chifukwa chake, kugwiritsa ntchito chitsulo chopepuka monga maziko a mphete yoboola ndiyo kugwiritsa ntchito kwambiri nkhaniyi mu dongosolo la brake.
