He kuleana koʻikoʻi nā ʻāpana kaʻa kaʻa i ka hōʻoia ʻana i ka palekana a me ka hana o nā kaʻa.Mai nā kaʻa hydraulic kuʻuna a hiki i nā ʻōnaehana braking regenerative holomua, ua ulu nui ka ʻenehana brake i nā makahiki.Ma kēia ʻatikala, e ʻimi mākou i kekahi o nā kumuhana wela e pili ana i nā ʻāpana kaʻa kaʻa, me nā kaʻa uila, nā mea holomua, ka hoʻokele autonomous, nā hoʻoponopono kaiapuni, a me nā hoʻomaikaʻi hana.
Nā kaʻa uila a me ka ʻenehana kaʻa
ʻO ka hoʻonui kaulana o nā kaʻa uila i hana i kahi pono no ka ʻenehana brake e hiki ke hoʻokō i nā ʻano ʻokoʻa o kēia mau kaʻa.ʻAʻole like me nā kaʻa hoʻohana ʻia i ka ʻaila maʻamau, hilinaʻi nā kaʻa uila i ka braking regenerative e lohi a kū.Hoʻihoʻi hou nā ʻōnaehana braking regenerative i ka ikehu e nalowale ana i ka wā e hoʻopaʻa ai a hoʻohana ʻia e hoʻopiha hou i nā pihi o ke kaʻa.
Ke nānā aku nei nā mea hana ʻāpana kaʻa i ka hoʻomohala ʻana i nā ʻōnaehana braking regenerative e hiki ke hāʻawi i ka hana hilinaʻi a paʻa.ʻO kahi paʻakikī me ka regenerative braking ʻo ia ka mea hiki ke hōʻemi i ka maikaʻi o nā pahu friction kuʻuna.Ke hana nei nā mea hana e lanakila i kēia pilikia ma o ka hoʻomohala ʻana i nā ʻōnaehana braking hybrid e hoʻohui i ka regenerative a me ka friction braking.
ʻO kahi ʻāpana ʻē aʻe o ka nānā ʻana no nā mea hana ʻāpana kaʻa kaʻa ka hoʻomohala ʻana i nā ʻōnaehana brake e hiki ke hoʻokō i ke kaumaha kiʻekiʻe o nā kaʻa uila.ʻOi aku ka kaumaha o nā kaʻa uila ma mua o nā kaʻa maʻamau ma muli o ke kaumaha o nā pila.Hiki i kēia paona hou ke kau aku i ke koʻikoʻi ma luna o nā kaʻa, e koi ana i nā ʻāpana ikaika a paʻa.
Nā mea kiʻekiʻe
I kēia mau makahiki i hala iho nei, ua ulu nui ka hoihoi i ka hoʻohana ʻana i nā mea holomua no nā ʻāpana ʻāpana.ʻO nā mea kiʻekiʻe loa, e like me ka carbon-ceramic composites, hāʻawi i ka hoʻomaikaʻi ʻana i ka hana, ka lōʻihi, a me ke kaumaha i hoʻemi ʻia, e hoʻolilo iā lākou i koho maikaʻi no nā kaʻa hana kiʻekiʻe.
He mea kaulana loa nā rotors brake carbon-ceramic i waena o nā mea makemake i nā kaʻa a me nā mea hana kaʻa kiʻekiʻe.Hana ʻia kēia mau rotors mai kahi mea i hoʻohui ʻia e hoʻohui i ka fiber carbon me ka ceramic.Hāʻawi lākou i nā pōmaikaʻi koʻikoʻi ma mua o nā rotors hao a i ʻole nā mea hao, me ka hoʻemi ʻana i ke kaumaha, hoʻomaikaʻi i ka wela, a me ka lōʻihi o ke ola.
Ke hoʻāʻo nei nā mea hana ʻāpana kaʻa kaʻa me nā mea holomua ʻē aʻe, e like me ka titanium a me ka graphene.Hāʻawi kēia mau mea waiwai i nā waiwai kūʻokoʻa i hiki ke pōmaikaʻi no nā ʻāpana brake, e like me ka ikaika kiʻekiʻe, ke kūpaʻa corrosion, a me ka friction haʻahaʻa.
ʻO ka hoʻokele kaʻawale a me nā ʻōnaehana braking
Ke hoʻomau nei ka hoʻomohala ʻana o ka ʻenehana hoʻokele autonomous, ke ulu nei ka pono no nā ʻōnaehana braking kiʻekiʻe e hiki ke ʻike a pane i nā pōʻino ma ke alanui.Ke hana nei nā mea hana ʻāpana kaʻa kaʻa i ka hoʻomohala ʻana i nā ʻōnaehana braking akamai e hiki ke hoʻohui pū me ka ʻenehana hoʻokele autonomous e hāʻawi i kahi ʻike hoʻokele palekana.
ʻO kekahi hiʻohiʻona o kahi ʻōnaehana braking akamai ʻo ia ka ʻōnaehana brake assist (EBA).Hoʻohana ʻo EBA i nā mea ʻike a me nā kāmera e ʻike i nā pōʻino hiki ke hoʻohana ʻia a hoʻopili maʻalahi i nā kaʻa inā ʻaʻole pane ka mea hoʻokele i ka manawa.Hiki i kēia ʻenehana ke kōkua i ka pale ʻana i nā pōʻino a hoʻemi i ka paʻakikī o nā hui ʻana.
ʻO kahi ʻāpana ʻē aʻe o ka nānā ʻana no nā mea hana ʻāpana kaʻa kaʻa ka hoʻomohala ʻana i nā ʻōnaehana brake-by-wire.Hoʻohana nā ʻōnaehana brake-by-wire i nā hōʻailona uila e hoʻomalu i nā kaʻa ma kahi o kahi ʻōnaehana hydraulic maʻamau.Hiki i kēia ʻenehana ke hāʻawi i ka mana pololei ma luna o ka ikaika braking a hōʻemi i ka pilikia o ka pau ʻole o ka haki.
Nā hoʻoponopono kaiapuni a me ka lepo pahu
ʻO ka lepo ʻōpala kahi kumu nui o ka haumia a hiki ke loaʻa ka hopena maikaʻi ʻole i ke kaiapuni.ʻO ka hopena, ke piʻi nei ke kaomi i nā mea hana o nā ʻāpana kaʻa kaʻa e hoʻomohala i nā pad brake haʻahaʻa haʻahaʻa a me nā rotors e hiki ke hōʻemi i ka lepo i hana ʻia i ka wā o ka braking.
ʻO kahi ala e hōʻemi ai i ka lepo pauka, ʻo ia ka hoʻohana ʻana i nā pad brake organic ma kahi o nā pad metallic.Hana ʻia nā pad organik mai nā fibers Kevlar a me aramid, e hana ana i ka lepo liʻiliʻi ma mua o nā pad metallic kuʻuna.ʻO kekahi ala ʻē aʻe, ʻo ia ka hoʻomohala ʻana i nā pad brake ceramic, kahi e hoʻohua ai i ka lepo liʻiliʻi ma mua o nā pad metala.
Hoʻonui i ka hana
Nui ka poʻe ʻoliʻoli kaʻa i ka hoʻomaikaʻi ʻana i nā ʻōnaehana kaʻa no ka hoʻomaikaʻi ʻana i ka hana.Ke pane nei nā mea hana ʻāpana kaʻa kaʻa i kēia koi ma ka hāʻawi ʻana i kahi ʻano o nā pad brake kiʻekiʻe, nā rotors, a me nā calipers hiki ke hāʻawi i ka mana hoʻomaha maikaʻi a hoʻemi.
