No ke aha e ʻaʻahu like ʻole ai nā pad brake, kahi e ʻimi ai i ke kumu
Nā mea
E lōʻihi ka lōʻihi o nā pad brake a me nā diski inā like ke ʻano o ka ʻaʻahu ma ka ʻaoʻao o waho a me loko, a like pū kekahi ma nā ʻaoʻao ʻākau a hema o ke kaʻa. Aneane hiki ʻole ke hoʻokō i ka like ʻole ma nā koʻi, akā ʻaʻole i hoʻokomo ʻia kēia i ka hoʻolālā.
ʻO kēia hoʻohana waiwai kokoke-pono, ma kahi o ka hōʻemi ʻana i nā kumukūʻai hana, kōkua pū kekahi i ka palekana.
Hiki i ka mīkini huki ma lalo o ka braking a i ʻole ka dynamic disc warping hiki ke hoʻoneʻe i ka mea hoʻokele i ke kūpaʻa a me ka mana.
He aha ke ola lawelawe o nā pale pale
He mea ʻole ke kamaʻilio e pili ana i ka waiwai awelika o ka lōʻihi o nā pads e ka mileage. Nui nā kumu e hoʻololi i kēia:
- ʻO ka hui pū ʻana o nā hiʻohiʻona o nā mea lining a me ka ʻili o nā disc a i ʻole nā pahu i ka hoʻonohonoho ʻana o ka hale hana;
- ʻO ke ʻano o ka hoʻokele ʻana o ka mea hoʻokele, pehea ka manawa e hoʻohana ai ʻo ia i nā kaʻa a me ka wikiwiki, overheating, ka hoʻohana ʻana i ka ʻenekini braking;
- ʻO ka makemake o ka mea nona ke koho ʻana i nā pads pani, ʻo ka ʻoihana a me ka hana, no ka nui, ʻoi aku ka nui o nā manaʻo kumuhana o nā kaʻa ma mua o ka pono maoli, me ka helu o ka lole;
- ke kūlana o ke alanui, ka loaʻa ʻana o nā abrasives, lepo a me nā kemika ikaika;
- ka mana nui o ka neʻe like ʻole a i ʻole ke ʻano holo wikiwiki-deceleration, ma muli o ka ʻāina;
- kūlana ʻenehana o nā mea o ka ʻōnaehana brake.
Eia naʻe, nui ka awelika o ka hōʻailona. Manaʻo ʻia e koi ʻia nā pads ma hope o 20 tausani mau kilomita.
Akā, hiki ke noʻonoʻo ʻia he hōʻailona maʻamau no nā kaʻa kīwila.
Nā kumu maʻamau o ka ʻaʻahu ʻaʻole like ʻole
Aia nā aʻa o kēlā me kēia pilikia, hiki iā mākou ke ʻike i nā mea nui. ʻO ka manawa pinepine, hiki ke hoʻoholo ʻia ke kumu e nā hiʻohiʻona kikoʻī o ka lole like ʻole.
I ka pau ʻana o ka pad hoʻokahi wale nō
I loko o kēlā me kēia pālua o ka disc brake pads, ua hoʻomaopopo ʻia e paʻi ʻia lākou i ka disc me ka ikaika like, a neʻe aku ma hope o ka hoʻokuʻu ʻana i ka synchronously a ma kahi mamao like.
I ka wā e hele mai ai nā hewa, ʻaʻole i hoʻokō ʻia kēia mau kūlana, ʻo ia ka hopena, hoʻomaka kekahi o nā pads e pau wikiwiki. A i ʻole e loaʻa iā ia ka ʻoi aʻe o ke koʻikoʻi, e lawe ana i ka ukana nui, a ʻaʻole hoʻi i hoʻihoʻi ʻia, e hoʻomau mau ana i ka luhi me ka ʻole o ke kaomi ʻana i ka laina kaʻa.
ʻO ka pinepine, ʻo ia ka lua o ka hihia i ʻike ʻia. ʻAʻole hiki ke ʻokoʻa ka ʻokoʻa i lalo me kahi mīkini asymmetrical me kahi caliper passive lana. Akā hiki ke paʻakikī ka lawe ʻana ma muli o ka ʻinoʻino a i ʻole ka ʻauʻau ʻana o nā ʻāpana. Paʻi hapa ʻia ka poloka, liʻiliʻi ka friction, akā mau.
Hana ʻia kēia i ka wā i ʻino ʻia ai ka ʻili o loko o ka pahu pahu a i ʻole nā mea alakaʻi. Ua haki nā kinematics, e kau ana ka poloka ma ke kūlana paʻi a i ʻole nā wedges.
Kōkua ia e hoʻololi i ka pahu hoʻoponopono caliper, maʻamau he piston, sila a me nā alakaʻi. Hiki iā ʻoe ke hele me ka hoʻomaʻemaʻe a me ka lubricating, akā ʻaʻole hiki ke hilinaʻi ʻia kēia. Hoʻohana ʻia ka momona kūikawā wale nō, ka wela kiʻekiʻe. I nā hihia koʻikoʻi, pono ʻoe e hoʻololi i ka hui caliper.
holoi wedge
ʻO ka mea maʻamau, ʻo ka ʻaʻahu ʻana o ka lining i nā uku like ʻole ma kahi o ka hana i hana ʻia i loko o nā pahu pahu multi-cylinder ikaika. I ka hala ʻana o ka manawa, hoʻopau lākou i ka hana ʻana i kahi paʻi like ʻole, ʻoiai ke ʻano like o ke kaomi wai.
Akā hiki ke hoʻololi i ka bracket me kahi mīkini me kahi piston hoʻokahi ma muli o ka corrosion a i ʻole ka lole kaumaha. Pono ʻoe e hoʻololi i ka caliper a i ʻole nā ʻāpana o ka mīkini alakaʻi.
Hiki ke loaʻa ka wedge ma ka ʻaoʻao o nā pā. ʻO kēia ma muli o ka hoʻokomo ʻana i nā pads hou ma kahi diski ʻaʻahu ʻole ʻia, pono e hoʻololi a hana ʻia paha.
ʻOi aku ka wikiwiki o nā pad ma ka ʻākau ma mua o ka hema
He ʻano ʻē aʻe paha ia. Ma ka ʻaoʻao ʻākau, loaʻa pinepine kēia ma muli o ke kaʻa ʻana i ka lima ʻākau, ʻoi aku ka kokoke i ke ala, ʻoi aku ka nui o ka wai a me ka lepo e komo i loko o ka friction zone.
Akā ʻaʻole kēia wale ke kumu, hiki i nā mea he nui:
- ma muli o ka lepo pulu hoʻokahi, hiki i ka corrosion wikiwiki o nā ʻāpana ma kekahi ʻaoʻao;
- ua lawelawe maikaʻi ʻia kekahi o nā mīkini;
- ʻO keʻano maʻamau,ʻaʻole iʻelemakule nā'āpana i ka manawa like;
- nā ʻāpana kīnā ʻole;
- ʻokoʻa ʻokoʻa ma muli o ABS a i ʻole ea i loko o ka ʻōnaehana;
- deformation o nā ʻāpana ma muli o ka overheating a i ʻole nā kumu mechanical;
- ʻelemakule o ka ʻili o loko o nā paipu kaʻa.
E like me ke kānāwai, hiki ke ʻike mua ʻia kēia kūlana e ka huki paʻa o ke kaʻa i ka ʻaoʻao ma lalo o ka braking.
ʻAʻahu like ʻole o nā pā pahu
ʻO nā ʻokoʻa hana nui o ka mīkini pahu ka ʻokoʻa kumu ma waena o ka hana o nā pads mua a me hope.
Hāʻawi ʻia kā lākou hana synchronous, akā ma lalo o nā kūlana kūpono o ka lole like. I ka wā lōʻihi, hoʻomaka kekahi o nā pads e ʻike i ka wedging geometric, a ʻo ke kaomi ʻana i kekahi e hoʻoholo wale ʻia e ke kaomi ma ka piston.
ʻO ke kumu ʻelua, ʻo ia ka hana ʻana o ka handbrake ma o ka asymmetrical drive o nā levers a me ka spacer bar. ʻO ka uhaki ʻana i ka hoʻoponopono a i ʻole corrosion e alakaʻi i ke kaomi ʻokoʻa, a me ka hoʻokuʻu ʻole ʻana.
Pono ka mīkini lima lima e mālama mau a hoʻololi i nā kaula. ʻAʻole wale nā pads e hoʻololi, akā pū kekahi o nā levers, nā pūnāwai, nā slats. Nānā pū ʻia nā pahu no ka palena ʻaʻahu ma ke anawaena o loko.
No ke aha e ʻoi aku ka wikiwiki o nā pads hope ma mua o nā pads mua?
ʻOi aku ka ikaika o nā kaʻa hope ma mua o ka mua, ma muli o ka hoʻohele hou ʻana o ke kaumaha o ka mīkini ma ke axle mua.
Hoʻomalu ʻia kēia e ka mana mechanical a i ʻole ka uila uila no ka pale ʻana i nā poloka. No laila, ʻo ka ratio theoretical o ke ola pad ma kahi o hoʻokahi a ʻekolu paha i makemake i ka hope.
Akā hiki i nā kumu ʻelua ke hoʻololi i ke kūlana.
- ʻO ka mua, ʻoi aku ka nui o ka lepo a me nā abrasives e lele i nā hui kuʻi hope. ʻO ka manawa pinepine, ʻo ia ka mea i ʻoi aku ka pale ʻana, ʻoi aku ka maikaʻi o nā pahu i kau ʻia ma hope.
- ʻO ka lua ka hopena o ka handbrake i kēlā mau hoʻolālā kahi e hoʻohana ai nā ʻōnaehana nui a me nā kaʻa i nā pads like. ʻO kāna mau hana hewa e alakaʻi ai i ka braking ma ka hele a me ka wikiwiki.
Aia kekahi mau kaʻa i ʻoi aku ka kiʻekiʻe o ka mana o nā kaʻa mua ma mua o ka hope o ka pau ʻana o nā pads e like me ia. Ma keʻano maʻamau, hiki i kekahi deviations ke alakaʻi i ka emiʻana o ka lōʻihi o ka hope.
