ʻAʻole i loli iki nā pūnaewele hōʻalima i ke kenekulia hope loa, no laila keʻano o kaʻenehana uila e kelepona i kahi hoʻololi o ke kai a ka poʻe holoʻokoʻa a me ka lehulehu i kaʻaeʻole e'āpana. ʻOiaiʻo nā kumuhana hydraulic kahiko ka pilikia, aia he mea hōʻoluʻolu i ka loaʻaʻana o kahi pilina pololei a me ka pilina ma waena o kou wāwae a me nā kāmaʻa wili aiʻole nā kāmaʻa ma nā kihiʻehā o kāu kaʻa. Hoʻopiʻi ka Brake-by-wire i kēlā pilina,ʻo ia ke kumu eʻikeʻia ai kaʻenehana e like me ka meaʻoi aku ka maikaʻi ma mua o ka mana o ka lolouila a iʻole ke kani uila .
ʻO ka Hui Māʻoluʻolu o nā Brakes Hydraulic
ʻO keʻano o ka hanaʻana o nā pūnaha hana kahiko no nā makahiki he nui,ʻo ka hoʻokauʻana i ka pedal freel ke hana i ka hoʻohuhu hydraulic i hoʻohanaʻia no ka hoʻouluʻana i nā kāmaʻa wāwae a iʻole nā pale. I nā'ōnaehana kahiko, hana ka papa i luna o kahi mea hydraulic inoa iʻikeʻia he "master cylinder". I nā'ōnaehana hou, kahi humuhumuʻana, i hana pinepineʻia e ka mimiki, hoʻonui i ka ikaika o ka paepae a hiki ke maʻalahi ke uhaki.
Ke hoʻoukaʻia ke kalaika, pono e hoʻoulu i ka wai hydraulic i nā laina wili. ʻO ka hopena ma hope o ka hanaʻana o nā kauā kau i kēlā me kēia huila, kahi e hoʻokala ai i ka rotor ma waena o nā pāpaʻi pahu aiʻole e kāomi i nā kāmaʻa hao i waho i loko o ka pahu.
Uaʻoi aku ka paʻakikī o nā pūnaewele hōʻano hou no kēiaʻano, akā e hana mau ana lākou ma ka kulekeleʻano likeʻole. Hiki ke hoʻohaʻahaʻa i nā mea hoʻolimalima a me nā mea hoʻolimalima'ūpala i ka nui o ka ikaika a ka mea hoʻokele e hoʻohui ai, aʻo kaʻenekini likeʻole me nā mana hana hilinaʻi a me nā mana hana hukiho hiki ke hoʻololi a hoʻokuʻu paha i nā kaʻa.
Ua hoʻohanaʻia nā kuʻemene a me nā hikulemole hiwahiwa wale nō ma nā mea hoʻokele. No ka mea, aia nā mea hoʻoiliʻia i ke alapila no nā kukui kukui a hoʻololi i nā hōʻailona, he mea maʻalahiʻole ke kelepona i loko o ka mea hoʻokele hikohulekolekolekole paha. Loaʻa nāʻenehana likeʻole mai nā OEMʻelua, akā,ʻo ka hopena palekana o nā pīpī ua loaʻa i kekahiʻoihanaʻoihana kālai'āina e mau nei ka hōʻailona e hana i kaʻenehana alaleka i kekahi kūpono maoli.
Hoʻolālāʻia ka Electro-Hydraulic Brakes
ʻO ka'ōhū o nā pūnaewele wili-by-wire i kēia manawa, hoʻohana ia i kahi model electro-hydraulic i kūʻole i ke kelepona. Aia nō i kēia mau pūnaewele nā pūnaewele hoʻomehana honua, akā,ʻaʻole hiki i ka mea hoʻokele ke hoʻololi koke i ka pahu cylinder ma ke kāomiʻana i ka pedal freel. Akā, ua hoʻoukaʻia ka pahu cylindi e kekahi mela uila a iʻole ka paila e hoʻonohonohoʻia e kahi pūnaewele.
Ke hoʻokomoʻia ka paepae uha i loko o kahi pūnaewele electro-hydraulic, hoʻohana ka pūnaewele i kaʻike mai kahi o nā meaʻike e hoʻoholo i ka nui o ka ikaika o ka hoʻokele i ka mana o kēlā me kēia huila. Hiki i ke kikowaena ke hoʻokomo i ka nui o ka pono o ka hau hydraulic i kēlā me kēia caliper.
ʻO kaʻokoʻa'ē aʻe ma waena o nā pūnaewele hōʻemi pūnaewele a me nā pūnaewele hōʻalokuʻu kūikawā,ʻo ia ka nui o ka pilikia. ʻO nā pūnaewele hōʻemi pūnaewele he nui ke hanaʻia ma lalo o nā koʻikoʻi kiʻekiʻe ma mua o nā'ōnaehana kahiko. Hiki ke hoʻohanaʻia nā mana o nā kaʻa hydraulic ma kahi o 800 PSI ma lalo o nā kūlana hoʻolālā maʻamau,ʻoiai ke hoʻomau nei nā pūnaewele electro-hydraulic Sensotronic i nā koi ma waena o 2000 a 2,300 PSI.
Nā Electromechanical SystemsʻOiaʻiʻo,ʻo Brake-by-Wire
ʻOiai ke hoʻohana nei nā'ōnaehana i nā'ōnaehana electro-hydraulic,ʻo kaʻenehana wili-by-wire pono loa ke lawe aku me ka hydraulics. ʻAʻole i hōʻikeʻia kēiaʻenehana i nā'ōnaehana hana no ka pilikino palekana o nā pūnaha hoʻolālā, akā ua hanaʻia i ka noiʻi a me nā hoʻokolohua nui.
ʻAʻole like me ka hana i ka hoʻokele electro-hydraulic,ʻo nā mea a pau i loko o kahi'ōnaehana electro-mechanical he'elepeleka. ʻO nā kupahu he mea hana i ka lolouila ma mua aʻe o ka hoʻohuweʻana i nā kauā hau, a ua hoʻomaluʻia nā mea a pau e kahi pūnaewele ma kahi o kahi kalaika kiʻekiʻe. Pono i kēia mau pūnaewele he nui o nā mea hou aku, e like me ka pāmahana, pāpī, a me ka mea hoʻokūkū hoʻokau i kēlā me kēia caliper.
Loaʻa i nā mana o Electromechanical nā pūnaeweleʻike paʻakikī ma muli o kēlā me kēia caliper e loaʻa i nāʻikepili helu he nui no ka hoʻoukuʻana i ka nui kūpono o ka ikaika. A ma muli o kaʻano pilikino-maikaʻi o kēia mau pūnaewele, pono i ka laikiniʻole, ke kula kiʻekiʻe no ka hoʻopukaʻana i nāʻike maʻalahi i nā papa.
ʻO ka pale umauma palekana kahi o ke keleponaʻo Brake-by-Wire
ʻOiai eʻoi aku ka palekana o nā pūnaewele hōkū-eleliko a me nā system electromechanical ma mua o nā'ōnaehana kahiko, no ka mea e pono ai ka hoʻohui houʻana me ABS, ESC, a me nā likehana likeʻole, ua paʻa lākou i nā pilikia no ka palekana. Hiki i nā'ōnaehana hōʻalima maʻamau ke hana i ka hāʻule, akā wale nō i ka nalowaleʻana o ka hoʻokele hydraulic e kāʻili wale i ka mea hoʻokele o ka hiki ke hoʻomaha a iʻole ka emi iho,ʻoiai he nui nā mana koho ponoʻole.
Nā mea hana Failuver, a me nā kulekele'ē aʻe no ka hoʻolālāʻana i nā polokalamu palekana palekana e like me ke kī keke-ala, e mālamaʻia e nā kūlana palekana no ka lawelaweʻana e like me ISO 26262
ʻO wai nā mea e hāʻawi ai i nā'ikehana Brake-by-Wire?
ʻO ka uku a me nā pūnaewele e hiki ke hana me ka heluna hōʻiliʻili o nāʻikepili e hana i kaʻenehana hōʻaleʻale electromechanical pono no ka hoʻolala nuiʻana, akā i kēia manawa wale nōʻelua o nā OEM i hoʻokolohua me nā pūnaewele hili.
Ua hoʻolako muaʻo Toyota i kahi pūnaewele hōʻemi elehu-hydraulic i ka makahiki 2001 no kona Estima Hybrid, a me nāʻano likeʻole o konaʻenehana hoʻokeleʻikeʻia (ECB) i loaʻa mai. Uaʻike muaʻia kaʻenehana i ka US no ka makahiki 2000 o ka makahiki Lexus RX 400h.
ʻO kahi hiʻohiʻona kahi iʻaeʻia ai kaʻenehana uila i kaʻikeʻoleʻana i ka manawa i hoʻokomoʻo Mercedes-Benz i kāna pūnaewele Sensotronic Brake Control (SBC), i hoʻokomoʻia no ka makahiki 2000. Ua hukiʻia kēia pūnaewele i ka makahiki 2006 ma hope o ka uku kumukūʻai ma ka makahiki 2004, me ka'ōleloʻana a Mercedes e hāʻawiʻia ka hana like o kāna pūnaewele SBC ma o ka pūnaewele hōʻemi pūnaewele.
