Hoʻololi nā pad brake ceramic i ka manaʻo kuʻuna o ka ceramic brake pads, ceramic brake pads i haku ʻia me ka ceramic fibers, hao-free filler substances, adhesives a me kahi mea metala liʻiliʻi.
ʻO nā pāpaʻi seramika kahi ʻano o nā pāpaʻi, nui nā mea kūʻai aku e kuhi hewa no ka seramika i ka wā mua, ʻoiaʻiʻo, ʻo nā pads seramika mai ka loina o nā seramika metala ma mua o nā seramika non-metallic. ma luna o ka friction ili, e like me ke ana, hiki ke hiki i 800 ~ 900 degere, a me kekahi i oi aku. Ma kēia wela kiʻekiʻe, e loaʻa i ka ʻili o ka pahu kaʻa ke ʻano like o ka cermet sintering, no laila ke kūpaʻa maikaʻi ka pā pahu i kēia mahana. ʻAʻole e hoʻohua ʻia ka hopena sintering ma kēia ʻano wela ma muli o ka piʻi ʻana o ka wela o ka ʻili e hoʻoheheʻe i ka mea o ka ʻili a hoʻohua hoʻi i ka cushion ea, kahi e hōʻemi nui ai i ka hana brake a i ʻole ka pau ʻana o ka haki ma hope o ka hoʻomau mau ʻana.
ʻO nā hiʻohiʻona o ka ceramic brake pad:
ʻO ka lepo liʻiliʻi ma nā huila; Ke ola lōʻihi o nā pā a me nā pālua; ʻAʻohe walaʻau/ʻaʻohe haʻalulu/ʻaʻohe pōʻino diski. ʻO ka hana kūikawā penei:
(1) ʻO ka ʻokoʻa nui loa ma waena o nā pad brake ceramic a me nā pad brake kuʻuna, ʻaʻohe metala. ʻO ka metala i loko o nā pad brake maʻamau ka mea friction nui, ʻoi aku ka ikaika o ka braking, akā nui ka lole, a maʻalahi ka leo. Ma hope o ka hoʻokomo ʻia ʻana o nā pad brake ceramic, i ka hoʻokele maʻamau, ʻaʻohe walaʻau like ʻole (ʻo ia hoʻi, ke kani ʻana o ke kani). No ka mea, ʻaʻole i loaʻa nā ʻāpana metala i loko o nā pā palaka seramika, ua pale ʻia ka walaʻau metala o ka paio ma waena o nā ʻāpana metala maʻamau a me nā ʻāpana ʻelua (ʻo ia hoʻi, nā pale pahu a me ka disc brake).
(2) Paʻa paʻa kuʻi. ʻO ke koena friction ka papa kuhikuhi hana koʻikoʻi o kēlā me kēia mea friction, e pili ana i ka hiki o ka brake pads. Ma ke kaʻina hana braking ma muli o ka friction i hoʻoulu ʻia ka wela, ka piʻi ʻana o ka mahana hana, ʻo ka mea maʻamau friction pad friction i hoʻopili ʻia e ka mahana, hoʻomaka ka friction coefficient e emi. Ma nā hoʻohana pono, e hoʻemi ʻia ka friction, no laila e hōʻemi i ka hopena braking. ʻAʻole i oʻo ka mea friction o nā pad brake maʻamau, a ʻoi aku ka kiʻekiʻe o ka friction coefficient, e hopena i nā mea palekana e like me ka nalowale o ke kuhikuhi, ke ahi, a me ka ʻoki ʻana i nā disc brake i ka wā o ka brake. ʻOiai ke piʻi ka mahana o ka disc brake i 650 degere, ʻo ka friction coefficient o ka ceramic brake pad e pili ana i ka 0.45-0.55, hiki ke hōʻoia i ka hana braking maikaʻi o ke kaʻa.
(3) Loaʻa i nā Ceramics ke kūpaʻa wela maikaʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa, maikaʻi ke pale ʻana i ka lole. ʻO ka mahana hoʻohana lōʻihi he 1000 degere, kahi e kūpono ai ka seramika no nā koi hana kiʻekiʻe o nā ʻano mea hoʻokiʻekiʻe hana kiʻekiʻe, a hiki ke hoʻokō i nā koi ʻenehana o ka wikiwiki kiʻekiʻe, palekana a me ke kūpaʻa ʻaʻahu kiʻekiʻe o nā pad brake.
(4) Loaʻa iā ia ka ikaika mechanical a me nā waiwai kino. Hiki ke pale i ke kaomi nui a me ka ikaika ʻā. ʻO nā huahana friction material i loko o ka ʻaha ma mua o ka hoʻohana ʻana, pono e hoʻoheheʻe, hui a me nā hana ʻenehana ʻē aʻe, i mea e hana ai i ka hui ʻana o ka pahu pahu. No laila, pono e loaʻa i ka mea friction ka ikaika mechanical e hōʻoia i ka ʻole o ka pōʻino a me ka ʻāpana i ka wā e hana ai a hoʻohana paha.
(5) He haʻahaʻa haʻahaʻa haʻahaʻa loa. Inā paha ʻo ia ka hanauna mua o nā huahana seramika o M09 a i ʻole ka hā o ka ʻehā o nā pad brake seramika o TD58, hiki iā ia ke hōʻoia i ka maikaʻi o ka hana braking o ke kaʻa e hōʻoia i ka palekana, a ʻo ke ʻano o ka attenuation thermal o nā pad brake he liʻiliʻi loa. .
(6) E hoʻomaikaʻi i ka hana o nā pale pale. Ma muli o ka wikiwiki o ka wela o nā mea seramika, ʻoi aku ka kiʻekiʻe o kona friction coefficient ma mua o nā pad brake metala i ka hana ʻana i nā brakes.
(7) Palekana. E hoʻohua koke mai nā pad brake i ka wela kiʻekiʻe i ka wā e hoʻopaʻa ai, ʻoi aku hoʻi i ka wikiwiki kiʻekiʻe a i ʻole ka ulia pōpilikia. Ma nā wela kiʻekiʻe, e emi ana ka heluna friction o ka pepa friction, i kapa ʻia ʻo thermal decay. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa o nā pale pale maʻamau, ke kūlana wela kiʻekiʻe a me ka piʻi ʻana o ka mahana o ka ʻaila ʻaila i ka wā o ka ulia pōpilikia e hoʻolōʻihi i ka lohi ʻana, a me ka nalowale o ka hopena braking haʻahaʻa haʻahaʻa.
(8) Hōʻoluʻolu. I loko o nā hōʻailona hōʻoluʻolu, hopohopo nui nā mea nona ka leo o nā pad brake, ʻoiaʻiʻo, ʻo ka walaʻau kekahi pilikia i hiki ʻole i nā pad brake maʻamau ke hoʻoponopono no ka manawa lōʻihi. Hoʻokumu ʻia ka walaʻau e ka friction maʻamau ma waena o ka friction plate a me ka friction disc, a ʻo nā kumu o kāna hana ʻana he paʻakikī loa, ʻo ka ikaika braking, ka wela disc brake, ka wikiwiki o ke kaʻa a me nā kūlana aniau ke kumu o ka walaʻau.
Eia kekahi, ʻokoʻa nā kumu o ka walaʻau ma nā ʻano ʻekolu o ka hoʻomaka ʻana o ka braking, ka hoʻokō braking a me ka hoʻokuʻu braking. Inā ma waena o 0 a me 550Hz ka alapine o ka walaʻau, ʻaʻole e ʻike ʻia ke kaʻa, akā inā ʻoi aku ia ma mua o 800Hz, hiki i ka mea nona ke ʻike i ka leo kaʻa.
(9) Nā hiʻohiʻona waiwai maikaʻi loa. ʻO nā pā palaka seramika e hoʻohana ana i nā mea nui o ka graphite/brass/advanced ceramics (non-asbestos) a me semi-metal a me nā mea ʻenehana kiʻekiʻe me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻana, ka paʻa paʻa, hoʻoponopono i ka pōʻino disc brake, pale kaiapuni, ʻaʻohe leo lōʻihi. ʻO ke ola lawelawe a me nā pono ʻē aʻe, e lanakila ai i nā pad brake kuʻuna ma luna o nā mea a me ke kaʻina hana i kēia manawa ʻo ia ka ʻoi loa o ka ʻoi loa o ka ʻoi loa o ke ao nei i nā pale pahu seramika holomua. Eia kekahi, he haʻahaʻa ka ʻike o ka ceramic slag ball, maikaʻi ka hoʻonui ʻana, a hiki ke hoʻemi ʻia ka ʻaʻahu ʻelua a me ka walaʻau o nā pad brake.
(10) Ke ola lawelawe lōʻihi. ʻO ke ola lawelawe he hōʻailona ia e hopohopo nui nei mākou, ʻo ke ola lawelawe o nā pad brake maʻamau ma lalo o 60,000 mau kilomita, a ʻo ke ola lawelawe o nā pad brake ceramic ma mua o 100,000 mau kilomita. ʻO ia no ka mea ʻo ka mea hoʻohālikelike kūʻokoʻa i hoʻohana ʻia i nā pad brake seramika he 1 wale nō i 2 mau ʻano o ka pauka electrostatic, a ʻo nā mea ʻē aʻe he mau mea non-electrostatic, no laila e lawe ʻia ka pauka e ka makani me ka neʻe ʻana o ke kaʻa, a ʻaʻole e pili i ka huila e pili ana i ka nani o ka huila. ʻOi aku ke ola o nā mea seramika ma mua o 50% kiʻekiʻe ma mua o ka semi-metal maʻamau. Ma hope o ka hoʻohana ʻana i nā pad brake ceramic, ʻaʻohe ʻoki (ʻo ia hoʻi, scratches) ma ka disc brake, kahi e hoʻonui ai i ke ola lawelawe o ka disc brake kaʻa mua e 20%.
