Nā pahu pahu, a i ʻole e like me ke noi a nā mea kūʻai aku.

ʻO nā pad brake, i kapa ʻia hoʻi nā pad brake kaʻa, e pili ana i ka mea hoʻoheheʻe i hoʻopaʻa ʻia ma ka pahu pahu a i ʻole ka disc brake e kaʻa me nā huila. Hoʻopili ʻia nā linings friction a me friction linings i ke kaomi o waho a hana i ka friction e hoʻokō i ke kumu o ka deceleration kaʻa.
ʻO nā pā kaʻa kaʻa i haku ʻia me ka pā kila, ka papa insulation adhesive a me ka poloka friction. Pono e pena ʻia ka pā kila no ka pale ʻana i ka pala. Hoʻohana ʻia ka SMT-4 furnace temperature tracker e ʻike i ka hāʻawi ʻana i ka mahana o ke kaʻina hana uhi e hōʻoia i ka maikaʻi.
ʻO ka loina hana o ka brake mai ka friction. Hoʻohana ʻia ka ʻāwili ma waena o nā pad brake a me nā disc brake (drums) a me nā huila a me ka lepo e hoʻololi i ka ikehu kinetic o ke kaʻa i ikehu wela frictional e hoʻōki i ke kaʻa. Pono e hāʻawi i kahi ʻōnaehana brake maikaʻi a maikaʻi hoʻi i ka ikaika braking paʻa, lawa a hiki ke hoʻopaʻa ʻia, a loaʻa i ka hoʻoili hydraulic maikaʻi a me ka hiki ke hoʻokuʻu wela e hōʻoia i ka ikaika i hana ʻia e ka mea hoʻokele mai ka pedal brake hiki ke hoʻouna piha ʻia i ka master cylinder A kēlā me kēia. sub-cylinder, a no ka pale ʻana i ka hāʻule hydraulic a me ka hoʻohaʻahaʻa ʻana ma muli o ka wela kiʻekiʻe. Hoʻokaʻawale ʻia ka ʻōnaehana kaʻa ma ke kaʻa i ʻelua mau ʻāpana: disc a me ka pahu, akā ma waho o ka uku kumukūʻai, ʻoi aku ka maikaʻi o nā pahu pahu ma mua o nā disc brakes.
ʻO ka "Friction" e pili ana i ka neʻe ʻana ma waena o nā ʻili pili o nā mea ʻelua e neʻe ana. Hoʻohālikelike ʻia ka ikaika frictional (F) i ka huahana o ka friction coefficient (μ) a me ke kaomi maʻamau kūpaʻa (N) ma luna o ka ʻili pili i ka friction, i hōʻike ʻia ma ke ʻano kino: F=μN. No ka ʻōnaehana kaʻa: (μ) e pili ana i ka huina hoʻoheheʻe ma waena o ka pā pahu a me ka disc brake, a ʻo N ka ikaika i hana ʻia e ka piston caliper brake ma luna o ka pahu pahu (Pedal Force). ʻO ka ʻoi aku ka nui o ka friction coefficient, ʻoi aku ka nui o ka friction i hana ʻia, akā e hoʻololi ka friction coefficient ma waena o ka pahu pahu a me ka disc ma muli o ka wela nui i hana ʻia ma hope o ka friction, ʻo ia hoʻi, hoʻololi ka friction coefficient (μ) me ka mahana. He ʻokoʻa ko kēlā me kēia ʻano o ka pā palaka ma muli o ka ʻokoʻa o ka mea. No laila, ʻokoʻa nā ʻāpana ʻokoʻa i nā mahana hana maikaʻi loa a me nā pae wela hana kūpono. ʻO kēia ka wā e kūʻai ai ʻoe i nā pad brake. He aha kāu e ʻike ai.
Ka lawe ʻana i ka ikaika braking
ʻO ka ikaika i hoʻokō ʻia e ka piston caliper brake ma nā pad brake i kapa ʻia: Pedal Force. Ma hope o ka hoʻonui ʻia ʻana o ka ikaika o ka mea hoʻokele ma ka pedal brake e ka lever o ka mīkini pedal, ua hoʻonui ʻia ka ikaika e ke kumu o ka ʻokoʻa ʻana o ka ʻokoʻa ma o ka hoʻoikaika mana, i hoʻohana ʻia e pana i ka pahu master brake. Hoʻohana ʻia ke kaomi hydraulic i hana ʻia e ka master cylinder brake i ka hopena o ka hoʻoili ʻana i ka mana incompressible, i lawe ʻia i kēlā me kēia sub-cylinder ma o ka hose brake, a hoʻonui ʻia ke kaomi e ka "Pascal principle" e pana i ka piston o ka sub-cylinder. e hooikaika ikaika ma na paleki. 'O ke kānāwai o Pascal' (Pascal's Law) 'o ia ho'i, ua like ke kaomi wai ma kēlā me kēia kūlana i loko o kahi pahu pani.
Loaʻa ka paʻi ma ka puʻunaue ʻana i ka ikaika i hoʻohana ʻia e ka wahi e loaʻa ai ka ikaika. Ke like ka paʻi, hiki iā mākou ke hoʻohana e hoʻololi i ka ratio o nā wahi i noi ʻia a loaʻa i ka ikaika e hoʻokō i ka hopena o ka hoʻonui ʻana i ka mana (P1=F1/A1=F2/A2=P2). Hoʻohana ʻia i ka ʻōnaehana brake, ʻo ka ratio o ke kaomi o ka master cylinder i ka cylinder ka ratio o ka piston area o ka master cylinder i ka piston area o ka cylinder.
Ua lako me: ABS
ABS: Anti-lock Brake System, e like me ka inoa i hōʻike ʻia, ʻo ia ka "Anti-lock Brake System". Ua ʻike nā kānaka a pau e hiki koke ana ka hopena braking ma mua o ka laka ʻana o nā kaila. Inā hiki ke hoʻopaʻa ʻia ka ikaika braking i ke kaulike me ka friction huila, e loaʻa ka hopena braking nui loa. Ke oi aku ka ikaika o ke kaa ma mua o ke kuʻi ʻana o ka huila, e hoʻopaʻa ʻia ka huila. Ke hoʻopaʻa ʻia ka huila, e hoʻololi ʻia ka paio ma waena o ka huila a me ka lepo mai ka "static friction" a i ka "dynamic friction". ʻAʻole wale ka hoʻohaʻahaʻa nui ʻana, akā ua nalowale ka hoʻokele. Hiki ke hahai. No ka mea, ʻo ka hoʻopaʻa ʻana o ka huila ka hopena o ka hoʻohālikelike ʻana ma waena o ka ikaika braking a me ka friction force ma waena o ka huila a me ka lepo, ʻo ia hoʻi, ʻo ka palena o ka laka ʻana o ke kaʻa i ka wā e holo ana ke kaʻa e pili ana i nā ʻano o ke kaʻa. pono'ī, ke kūlana o ka ʻili o ke alanui, ke kihi hoʻonohonoho, a me ka paʻi kaʻa.
ʻO nā hiʻohiʻona o ka ʻōnaehana hoʻokuʻu "ʻokoʻa i kēlā me kēia manawa". Hoʻohana ʻo ABS i nā mea ʻike holo kaʻa i hoʻokomo ʻia ma nā huila ʻehā no ka hoʻoholo ʻana inā paʻa nā kaʻa, hoʻopau i nā kumu maopopo ʻole o ka naʻau o ke kanaka, a me ka hoʻomalu pono ʻana i ka hoʻokuʻu ʻana i ka manawa o ke kaomi hydraulic o ka cylinder brake e pale ai i ka laka mai ka laka ʻana. . Hoʻohana ka hapa nui o ka ABS i kēia manawa i kahi hoʻolālā e hiki ke hoʻomau a hoʻokuʻu i 12 a 60 mau manawa i kekona (12~60 Hz). Hoʻohālikelike ʻia me nā manawa 3 a 6 o nā mea hoʻokūkū ʻoihana kiʻekiʻe, he kiʻekiʻe kiʻekiʻe o ka hana.
ʻO ke kiʻekiʻe o ke alapine o ka heʻe ʻana, ʻoi aku ka nui ʻO ka ikaika braking hiki ke mālama ʻia ma ka lihi kokoke i ka palena. ʻO ka pololei a me ka hilinaʻi i hiki i ka ABS ke hoʻokō ua ʻoi aku ma mua o nā palena kanaka, no laila ke ʻōlelo nei mākou: ʻO ABS ka mea waiwai nui loa no ke kālā ke kūʻai aku i kaʻa. ʻOi aku ka pilikia pili o Air-Bag.
