ʻAʻole mea hou ke kaʻina hana o ka uhi ʻana i ka zinc iron brake disc.I ka wā o ke kaʻina hana, hoʻomaʻemaʻe ʻia ka diski me ka grit iron angular grit a kau ʻia kahi papa zinc.Ua kapa ʻia kēia hana ʻo sherdizing.Ma kēia kaʻina hana, hoʻoheheʻe ke arc uila i ka pauka zinc a i ʻole ka uea i loko o ka pahu a hoʻolele ʻia ma ka ʻili diski.Ma kahi o 2 mau hola e wehe ai i ka disc brake.ʻO kona mau ana he 10.6 iniha ke anawaena me ka 1/2 iniha ka mānoanoa.E hoʻohana ana nā pale pale ma ka 2.65 iniha waho o ka diski.
ʻOiai ke hoʻohana mau ʻia nei nā disc brake hao e hana i kekahi mau kaʻa, ke ʻimi nui nei nā mea hana i nā mea ʻē aʻe e hana ai i kēia mau huahana.No ka laʻana, hiki i nā mea haʻahaʻa māmā ke hiki ke hoʻonui i ka hana braking a hoʻemi i ke kaumaha o ke kaʻa.Eia naʻe, hiki ke hoʻohālikelike ʻia ko lākou kumukūʻai me ka hao hao.ʻO ka hui pū ʻana o nā mea hou he koho maikaʻi loa ia e hoʻonui ai i ka pono wahie o ke kaʻa a hoʻomaikaʻi i ka hana.Aia ma lalo iho kekahi mau pono o nā disc brake ma muli o ka alumini.
Ma ka ʻāina, ua hoʻokaʻawale ʻia ka mākeke honua no nā disc brake i ʻekolu mau ʻāpana: ʻAmelika ʻAmelika, ʻEulopa, a me Asia Pacific.I ʻEulopa, ua hoʻokaʻawale ʻia ka mākeke e Farani, Kelemānia, Italia, Sepania, a me ke koena o ʻEulopa.Ma Asia-Pākīpika, ua manaʻo ʻia ka mākeke no ka hoʻoheheʻe ʻia ʻana o ka hao ma kahi CAGR ma luna o 20% e 2023. ʻO ka Middle East a me ʻApelika e manaʻo ʻia e ulu i ka wikiwiki loa i nā makahiki e hiki mai ana, me kahi CAGR ma kahi o 30% .Me ka ulu ʻana o ka ʻoihana kaʻa, ke kūʻai nui nei nā ʻoihana e kū nei i nā huila ʻelua.
ʻOiai ka maikaʻi o nā disc brake aluminika, loaʻa kekahi mau hemahema i nā disc brake cast iron.He palupalu ka alumini maʻemaʻe a he haʻahaʻa haʻahaʻa loa kona pale ʻana i ka lole, akā hiki i nā alloys ke hoʻomaikaʻi i kāna hana.Hiki i nā disc brake alumini ke hoʻomau no nā makahiki he nui, e hōʻemi ana i ka nui unsprung e 30% a i kanahiku pakeneka.A maʻalahi lākou, kūpono ke kumu kūʻai, a hiki ke hana hou.ʻOi aku ka maikaʻi ma mua o nā disc brake hao.
Kāpena kalapona
ʻAʻole like me nā disc brake maʻamau, hiki i nā carbon-carbon ke kū i nā wela kiʻekiʻe loa.ʻO nā papa i ulana ʻia a me nā papa fiber-based e ʻae iā ia e pale i ka hoʻonui ʻana i ka wela me ka māmā.He kūpono kēia mau waiwai no nā disc brake, i hoʻohana pinepine ʻia i nā moʻo heihei a me nā mokulele.Akā, aia kekahi mau hemahema.Inā makemake ʻoe e hauʻoli i nā pōmaikaʻi o nā disc brake carbon-fiber, pono ʻoe e ʻike liʻiliʻi e pili ana i kā lākou hana hana.
ʻOiai he nui nā pōmaikaʻi o nā disc brake carbon i ke kahua heihei, ʻaʻole kūpono lākou no ka hoʻokele i kēlā me kēia lā.ʻAʻole lākou e kū i ka wela o ke alanui a nalowale ka mānoanoa o kahi prototype carbon disc i ʻekolu a ʻehā millimeters o ka mānoanoa i 24 mau hola o ka hoʻohana mau ʻana.Pono nō hoʻi nā ʻāpana kalapona i nā uhi kūikawā no ka pale ʻana i ka hoʻoheheʻe wela, hiki ke hopena i ka ʻino nui.A, he kiʻekiʻe ke kumu kūʻai o nā disc kalapona.Inā ʻoe e ʻimi nei i kahi disc brake carbon kiʻekiʻe, e noʻonoʻo i kekahi o nā mea maikaʻi loa o ka honua.
Ma waho aʻe o nā pōmaikaʻi mālama kaumaha, ʻoi aku ka lōʻihi o nā disc brake carbon-ceramic.ʻOi aku ka lōʻihi ma mua o nā disc brake maʻamau a hiki i ke ola o ke kaʻa.Inā ʻaʻole ʻoe e hoʻokele i kēlā me kēia lā, hiki iā ʻoe ke hoʻohana i hoʻokahi disc brake carbon-ceramic no nā makahiki.ʻO ka ʻoiaʻiʻo, ʻoi aku ka lōʻihi o nā disc ceramic carbon ma mua o nā disc brake maʻamau, ʻoiai ke kumu kūʻai kiʻekiʻe.
ʻOi aku ka kiʻekiʻe o ka pākuʻi ʻana o nā disc brake carbon-ceramic ma mua o nā dis cast-iron, e hōʻemi ana i ka manawa hoʻāla braking ma ka ʻumi pakeneka.Hiki i ka ʻokoʻa he ʻumi kapuaʻi ke hoʻopakele i nā ola kanaka, a me ka pale ʻana i ka pōʻino kino o ke kaʻa.Me ke kaʻa kaʻa, pono ka disc carbon-ceramic no ka hana o ke kaʻa.ʻAʻole ia e kōkua wale i ka mea hoʻokele, akā e hoʻomaikaʻi hou i ka palekana o ke kaʻa.
phenolic resin
ʻO ka resin Phosphoric kahi ʻano mea i hoʻohana ʻia i nā disc brake.ʻO kāna mau waiwai paʻa maikaʻi me ka fiber e lilo ia i mea pani maikaʻi loa no ka asbestos.Ma muli o ka pākēneka resin phenolic, hiki ke paʻakikī a ʻoi aku ka paʻakikī o nā disc brake.Hiki ke hoʻohana ʻia kēia mau hiʻohiʻona e pani i ka asbestos i nā disc brake.Hiki i kahi disc brake phenolic resin kiʻekiʻe ke ola i ke ola, ʻo ia ke kumu kūʻai haʻahaʻa haʻahaʻa.
ʻElua ʻano o ka resin phenolic i nā disc brake.ʻO kekahi he resin thermosetting a ʻo kekahi mea non-polar, non-reactive.Hoʻohana ʻia nā ʻano resin ʻelua e hana i nā disc brake a me nā pad.Hoʻohana ʻia ka resin phenolic i nā pad brake pāʻoihana no ka mea e decomposes ma kahi o 450°C, aʻo ka polyester resin decomposes ma 250-300°C.
He kuleana koʻikoʻi ka nui a me ke ʻano o ka binder i ka hana friction o kahi disc brake phenolic resin.ʻOi aku ka liʻiliʻi o ka resin phenolic i nā loli wela ma mua o nā mea ʻē aʻe, akā hiki ke hoʻopaʻa ʻia me kekahi mau mea hoʻohui.No ka laʻana, hiki ke hoʻololi ʻia ka resin phenolic me ka wai cashew nut shell no ka hoʻomaikaʻi ʻana i kona ʻano paʻakikī a me ka helu friction ma 100°.ʻO ke kiʻekiʻe o ka pākēneka o CNSL, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa.Eia nō naʻe, ua hoʻonui ʻia ke kūpaʻa wela o ka resin, a ua hoʻemi ʻia ka mae a me ka hoʻihoʻi ʻana.
ʻO ka ʻaʻahu mua e hoʻokuʻu ʻia nā ʻāpana mai ka resin a hana i kahi pāpū mua.ʻO kēia pāpū mua ke ʻano maʻamau o nā mea frictional.He kaʻina hana hoʻoikaika kēia, kahi e hoʻopili ai nā fiber kila a me ke keleawe paʻakikī kiʻekiʻe a i ʻole nā ʻāpana keleawe me ka diski.ʻOi aku ka paʻakikī o kēia mau ʻāpana ma mua o ka paʻakikī o ka disc.E ʻohi pū ka pāpū i nā ʻāpana lole micrometric a me submicrometric.
