ʻO ke kumukūʻai, akā mau loa: nā disc brake ceramic

ʻO kahi mokulele e komo ana i ka lewa o ka Honua e ʻike i ke kūʻē ʻana i ka ea. ʻO ia ke kumu i loaʻa ai i nā capsule space a me nā shuttles ka pale wela e hiki ke kū i nā wela kiʻekiʻe. Ua loaʻa i kēia mau tile seramika ko lākou ala i ka ʻoihana kaʻa ma ke ʻano o nā disc brake. Ma hope o nā mea a pau, ʻoi loa ka hopena o ka ʻōnaehana brake e nā wela kiʻekiʻe ma muli o ka friction.

He aha ke ano o na brake seramika?

Ke lohe nei i ka ʻōlelo " pālolo ”, manaʻo paha ʻoe i nā seramika. ʻOiaʻiʻo , ua koi nui nā ʻāpana seramika i ka ʻoihana. ʻO kā lākou kūikawā ʻO ka hopena insulating ikaika e kū'ē i ka piʻi ʻana o ka mana a me ka wela e lilo lākou i mea kūpono no nā kaiapuni koʻikoʻi .

Hoʻohana nā kaʻa i kahi mea seramika kūikawā: ʻO ka composite o ke kalapona kalapona a me ka silicon carbide he mea hoʻohui kūpono no ka hoʻomoʻa ʻana i ka ikehu frictional kiʻekiʻe.

No laila, ua hoʻolako ʻia nā pahu seramika me hoʻokahi a ʻoi aku paha nā mea i hana ʻia o kēia mea, i loaʻa nā pono a me nā hemahema .

Kūpono e kū'ē i ka hopena mae

Hana nā kaʻa o ke kaʻa ma ke kuʻi. . Hoʻokomo ʻia ka mea lawe paʻa me ka uhi ʻana i ka mea hoʻololi, hana i ka ikehu frictional, a laila e hōʻemi i ka ikehu o ka neʻe. Hoʻopuka ka friction i ka wela, hiki ke pilikia.
Ke hoʻokokoke ka mahana hoʻoheheʻe i ka helu heheʻe o ka mea hoʻololi, ʻo ia hoʻi ka diski a pahu paha , ua hoemiia ka hopena braking . I loko o nā pahu kaʻa kaʻa kahiko, alakaʻi kēia i kekahi manawa i ka pau ʻole.

ʻO kēia kahi e hāʻawi ai nā disc brake ceramic i ka hopena. . ʻO kā lākou mea hana he wahi heheʻe kiʻekiʻe loa i hiki ʻole ke loaʻa ma lalo o nā kūlana hoʻokele paʻakikī loa. ʻAʻole māmā a palekana nā disc brake carbon ceramic ; me ka hoʻohana maʻamau, mau loa lākou. Kau lawelawe a hiki i 350 km ʻo ia ke kūlana no kēia mau mea.

Ma muli o nā waiwai waiwai, hiki ke hoʻopaʻa ʻia nā disc brake kila hina hina i ka corrosion. . Ke hilinaʻi nui nei kēia mau modula i kā lākou hopena hoʻomaʻemaʻe ponoʻī ma lalo o nā kūlana hoʻokele maʻamau.

Ma ke ʻano he mea hao ʻole, ʻaʻole loa ka paʻakai a me ka corrosion ka carbon-ceramic composite. . ʻO ka loaʻa ʻole o ka uila a me ka abrasion e pili ana i ka papa ʻōpala i ka wā e hoʻopaʻa ʻia ai kekahi mea nui i ka pale ʻana o nā disc brake carbon-ceramic.

ʻO ka pilikia nui: ka wela wela

ʻAʻole komo hou ka wela i hana ʻia e nā disc brake carbon-ceramic a no laila ua ʻike ʻia nā mea a puni i ka wela. . I ka hopena o ka hoʻoulu ʻana i ka wela, pono e pale ʻia nā hose brake a me nā kaula sensor me ka insulation fiber ceramic.

Ua ana ʻia ka palena ʻana i nā mahana ma kēia mau modula a hiki i 1600°C. Pono nā disiki palaka seramika i nā pad brake like. No laila, ʻoi aku ka paʻakikī o ka hoʻololi ʻana i nā disc brake kila me nā disc brake ceramic ma mua o ka mea maʻamau.

ʻAʻohe kālepa i kēia manawa

Hoʻoheheʻe ʻia nā disc brake kila hina hina a hoʻoheheʻe ʻia i ka nui . Ke hele hewa kekahi mea, hoʻoheheʻe ʻia ka disc brake a hoʻoheheʻe ʻia. ʻAʻohe pohō waiwai ma kēia kaʻina hana.

ʻAʻole hiki ke hoʻoheheʻe ʻia nā disc brake carbon-ceramic kīnā ʻole. . Hiki iā lākou ke ʻoki ʻia a hoʻohana ʻia ma ke ʻano he mea hoʻohui i ka ʻoihana kūkulu. Eia naʻe, ʻaʻole pili ka hana hou ʻana o nā ʻōpala a me nā mea koena, maʻamau i ka hana metala, ma ʻaneʻi. .

ʻO kēia kekahi o nā kumu pipiʻi loa nā disc brake carbon ceramic . No ka hoʻohālikelike: hiki ke kūʻai maʻalahi ke kumukūʻai ceramic a hiki i ka €10 (± £000) . ʻAʻole ia e uku no nā kaʻa ʻohana maikaʻi. No laila ka hoʻonohonoho paʻamau mālama ʻia no nā limousine, nā kaʻa haʻuki, nā kaʻa heihei ʻoihana, nā kaʻa CIT и nā kaʻa kaua .

Eia nō naʻe, hiki i ka neʻe uila ke alakaʻi i ka hoʻohana maʻamau . Ma waho aʻe o ka hana braking maikaʻi loa a me ka lōʻihi kūʻokoʻa, He māmā loa nā pahu kalapona kalapona . I loko o kahi kaʻa uila, ʻo kēlā me kēia auneke i mālama ʻia e pili koke i kona laulā. No laila, hiki i nā disc brake carbon-ceramic ke kōkua i ka mālama kaumaha. Eia naʻe, lōʻihi loa kēia.

ʻO ka hoʻohana pono ʻana i nā seramika

Eia naʻe, i ka hoʻohana 'ana o ʻO nā ʻāpana seramika i nā kaʻa maʻamau ua kūpono . Ma kahi o ka hoʻololi ʻana i nā huila kila me nā ʻāpana carbon-ceramic, kahi koho kūpono ʻo ia ka hoʻokomo ʻana i nā pā palaka seramika.

Loaʻa nā pad brake seramika mai nā mea hana kaulana ma ke ʻano he mea kōkua . Hoʻokomo ʻia lākou ma ke ʻano like me nā pad brake maʻamau. Hāʻawi kā lākou hoʻohana kekahi mau pono:

- hoʻonui i ke kūpale ʻaʻahu - liʻiliʻi abrasion – hoemi ka walaau - ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana me kahi disc brake pulu

Hana kaʻa Hiki ke hoʻohālikelike ʻia nā pad brake ceramic me nā pads kuʻuna. Bea i ka manao inā hoʻolako ʻia kāu kaʻa me nā rim nani, ke hana nei ʻoe iā ʻoe iho me ka hoʻohana ʻana i nā pad brake ceramic. . ʻO ka abrasion weliweli e waiho i kahi lepo lepo paʻakikī e paʻakikī ke hoʻopau. ʻO nā pad brake seramika ka mea e emi ai ka abrasion.

ʻOi aku ka pīhoihoi nā pahu pahu kūʻai kūʻai me nā pale pale seramika. Hāʻawi nā mea hana branded i nā kumukūʻai no kēia hopena ʻaʻole i ʻoi aku ma mua o nā kumukūʻai o nā pahu pahu kuʻuna: ʻo ka pahu pahu ATE, me ka disc brake, linings a me nā ʻāpana ʻē aʻe, nā kumukūʻai mai kahi kokoke. €130 (± £115) .

ʻAʻole kēia he mea nui loa no kahi huahana OEM maikaʻi mai kahi mea hoʻolako kaulana. . Pono kēia mau kumukūʻai haʻahaʻa e koho i kēia hiʻohiʻona i kāu mālama ʻana i ka brake aʻe.

E koho mau i ka hana hou

ʻO ka hoʻomohala ʻana i nā disc brake ma mua o ka hoʻohana ʻana i nā seramika. ʻO ka hoʻomohala hou loa ʻo nā drive hybrid: kuʻuna hina hina hoʻolei kila paleki disk riveted i ka alumini paʻa . Ma kahi e pono ai ka ʻaʻahu a me ka wela wela, hāʻawi nā disc brake hybrid i ka hana piha.

Eia ka hua'ōlelo "mass": ʻaneʻane ʻaʻole hoʻohana ʻia nā disc brake maʻalahi i kēia mau lā . He kūlana maʻamau nā disc brake pālua ʻelua ma ke axle mua.
Eia naʻe he nui na pomaikai hāʻawi ʻia e kēia mau mea hou e like me ka hoʻomaikaʻi ʻana i ka wela a me ka hana , hele pū me ka nuipa i hoʻohui ʻia.

Eia naʻe, hiki ke hoʻopau ʻia kēia i nā kikoʻī ʻē aʻe: kahi i hoʻohui ʻia ai ke kila kila kaumaha i ke kaumaha holoʻokoʻa o ke kaʻa, ʻo nā disc brake hybrid kahi alumini māmā . Hana ʻia ka ʻāpana hoʻohui ma waena o ke apo palaka a me ka huila metala māmā i nā disc brake hana kiʻekiʻe .

ʻOiaʻiʻo, he haʻawina liʻiliʻi wale kēia i ka hoʻohaʻahaʻa kaumaha. . Eia nō naʻe, no ka mea, ʻo nā disc brake he mea hoʻoneʻe koʻikoʻi, ʻoluʻolu e hoʻemi i ke kaumaha. ʻO ka disc brake māmā e hoʻemi iki i ke kaulike ʻoiai e mālama ana i ka mīkini axle steer paʻakikī.

ʻAʻohe ʻokoʻa i ka maikaʻi hiki ke hoʻohālikelike ʻia ka ikaika o ka aluminika i loko o ke kila kila .

No ke aha ʻaʻole alumini ka rim holoʻokoʻa?

Ka hana ʻana i ka disc brake holoʻokoʻa mai ka alumini hiki ʻole no nā kumu ʻelua:

– wahi hehee haahaa - ʻaʻole lawa ka ikaika

alumini hehee ma 600°C . Ke alakaʻi maʻalahi ka hana braking maʻamau i nā mahana ma luna o 1000 ° C , a no laila e hāʻule ka metala māmā ma hope o kekahi mau hoʻāʻo braking.

A ʻoi aku ma mua o kēlā: hiki i ka alumini ke abrasion. ʻAʻole ʻae ʻia ka ʻaʻahu me ka hoʻopaʻa ʻana. No laila, ʻo ka hoʻohana ʻana i ka metala māmā e like me ke kumu no ke apo hoʻopaʻa ʻia ka hoʻohana hope loa o kēia mea i loko o ka ʻōnaehana brake.
