E hoʻolako ʻia kēlā me kēia kaʻa me kahi ʻōnaehana braking, ʻo nā mea hoʻokele o ia mea he mau pad brake e pili ana me ka pahu pahu a diski paha.ʻO ka hapa nui o nā pads he friction linings.E heluhelu i nā mea a pau e pili ana i kēia mau ʻāpana, kā lākou ʻano, hoʻolālā a me ke koho kūpono i ka ʻatikala.
He aha ke ʻano o ka pale paʻa?
ʻO ka pale pad lining (friction lining) he mea ia o nā mea hana o nā kaʻa kaʻa, e hōʻoiaʻiʻo ana i ka hana ʻana o ka torque braking ma muli o nā ikaika frictional.
ʻO ka lining friction ka ʻāpana nui o ka pahu pahu, pili pololei ia me ka pahu pahu a i ʻole disc i ka wā e hoʻopaʻa ai i ke kaʻa.Ma muli o nā mana frictional e kū mai ana mai ka hoʻopili ʻana me ka pahu / disc, hoʻopili ka lining i ka ikehu kinetic o ke kaʻa, hoʻololi iā ia i ka wela a hāʻawi i ka emi ʻana o ka wikiwiki a i ʻole ka pau ʻana.Loaʻa i nā linings ka nui o ka friction me ka hao hao a me ke kila (mai kahi i hana ʻia ai nā pahu pahu a me nā disc), a ma ka manawa like ke kūpaʻa kiʻekiʻe e ʻaʻahu a pale i ka ʻaʻahu nui o ka pahu / disc.
I kēia mau lā, he nui nā ʻano o nā linings brake pad linings, a no ke koho pololei ʻana i kēia mau ʻāpana, pono e hoʻomaopopo i kā lākou hoʻohālikelike a me ka hoʻolālā.
ʻO nā ʻano a me ka hoʻolālā ʻana o nā pale pale pale
Hiki ke hoʻokaʻawale ʻia nā linings friction o nā pad brake i nā pūʻulu e like me ke kumu, ka hoʻolālā a me ka hoʻonohonoho ʻana, a me ke ʻano i hana ʻia ai.
Wahi a ke kumu, ua māhele ʻia nā pads i ʻelua ʻano:
• No ka pahu pahu;
• No nā kaʻa disc.
ʻO ka pahu pahu pahu he pā arcuate me kahi radius waho e pili ana i ka radius o loko o ka pahu.I ka wā e hoʻomaha ai, hoʻomaha nā lining i ka ʻili o loko o ka pahu, e hoʻemi ana i ka wikiwiki o ke kaʻa.Ma ke ʻano maʻamau, ʻo nā linings friction drum brake he wahi hana nui.Hoʻolako ʻia kēlā me kēia mīkini kaʻa huila me nā linings ʻelua e kū pono ana kekahi i kekahi, e hōʻoiaʻiʻo ana i ka hāʻawi like ʻana o nā ikaika.
ʻO nā ʻāpana hoʻopaʻa diski he mau papa pālahalaha o ka crescent a i ʻole nā ʻano ʻano ʻē aʻe e hāʻawi i ka wahi pili loa me ka disc brake.Hoʻohana ʻia kēlā me kēia mīkini kaʻa kaʻa huila i ʻelua mau pad, ma waena kahi i hoʻopaʻa ʻia ai ka disc i ka wā e hoʻopaʻa ai.
Eia kekahi, ua hoʻokaʻawale ʻia nā linings brake pad i ʻelua pūʻulu e like me kahi o ka hoʻonohonoho ʻana:
• No nā kaʻa huila - mua, hope a me ke ao holoʻokoʻa;
• No ke kaʻa kaʻa kaʻa (me ka pahu ma ke kumu propeller).
Ma ke ʻano, ʻo nā linings friction he mau papa i hoʻoheheʻe ʻia mai nā haku mele polymer me kahi ʻano paʻakikī.Aia ka haku mele i nā ʻāpana like ʻole - ka hoʻokumu ʻana i ka frame, ka hoʻopiha ʻana, ka hoʻopau ʻana i ka wela, nā binders a me nā mea ʻē aʻe.I ka manawa like, hiki ke hoʻokaʻawale ʻia nā mea āpau i hana ʻia ai nā linings i ʻelua mau pūʻulu nui:
• Asbestos;
• ʻAʻohe asbestos.
ʻO ke kumu o nā linings asbestos, ma muli o ka maʻalahi o ka hoʻomaopopo ʻana, nā fibers asbestos (i kēia lā he asbestos chrysotile palekana palekana), e hana ana ma ke ʻano he papa pā e paʻa ai ke koena o nā mea.He palupalu ia mau pads, akā i ka manawa like he kiʻekiʻe kiʻekiʻe o ka friction, pale lākou i ka hoʻohana nui ʻana o ka pahu / disc a loaʻa ka pae leo haʻahaʻa.I nā huahana asbestos-free, pāʻani nā polymer a i ʻole nā mineral fibers i ke ʻano o ke ʻano o ka haku mele, ʻo ia mau overlay e hoʻokō me nā kūlana kaiapuni, akā ʻoi aku ka maikaʻi a ma kekahi mau mea i ʻoi aku ka maikaʻi o nā hiʻohiʻona hana (ʻoi aku ka paʻakikī, pinepine ka walaʻau, etc. .).No laila, hoʻohana nui ʻia nā lining asbestos friction i kēia lā.
Hoʻohana ʻia nā mea polymeric like ʻole e like me nā mea hoʻopihapiha i ka hana ʻana i nā overlays, polymers, resins, rubbers, etc. .Ma kahi o kēlā me kēia mea hana e hoʻohana i kāna mau meaʻai ponoʻī (i kekahi manawa kūʻokoʻa), no laila hiki ke ʻokoʻa ke ʻano o nā linings friction.
Hana ʻia nā lining friction me ka hoʻohana ʻana i ʻelua ʻenehana nui:
• Ke kaomi anu;
• Ke kaomi wela.
I ka hihia mua, ua hoʻokumu ʻia nā linings mai ka hui ʻana i hoʻopau ʻia i loko o nā pahu kūikawā me ka ʻole o ka hoʻomehana ʻana.Eia nō naʻe, hoʻohana nui nā mea hana i ka mālama wela o nā huahana ma hope o ka hana ʻana.I ka lua o ka hihia, paʻi ʻia ka hui ʻana i loko o nā mold wela (electric).Ma keʻano he kūlana, me ka paʻi anuanu, loaʻa nā linings liʻiliʻi liʻiliʻi, me ka paʻi wela, ʻoi aku ka maikaʻi o nā huahana, akā ʻoi aku ka maikaʻi.
ʻAʻole pili i ke ʻano o ka hana ʻana a me ka haku mele ʻana, ma hope o ka hana ʻana, ua hoʻonani ʻia nā linings a kau ʻia i nā hana ʻē aʻe.Ke kūʻai aku nei nā lining friction ma nā ʻano hoʻonohonoho like ʻole:
• Nā uhi me ka ʻole o nā puka kau a me nā mea hoʻopaʻa;
• Nā uhi me nā puka kau i wili ʻia;
• Hoʻopiliʻia me nā puka a me nā mea hoʻopaʻa;
• Hoʻopiha piha i nā pale - nā linings i kau ʻia ma ke kumu.
ʻO nā linings friction o nā pad brake me nā puka ʻole he mau ʻāpana āpau i hiki ke hoʻoponopono ʻia i nā pad brake o nā kaʻa like ʻole, nona nā ana kūpono a me nā radius.ʻO nā uhi me nā lua he kūpono ia no kekahi mau hiʻohiʻona kaʻa, hiki ke hoʻokomo iā lākou ma nā pads me kahi hoʻonohonoho ʻokoʻa o nā lua wale nō ma hope o ka wili hou ʻana, a i ʻole hiki ʻole.ʻO nā uhi piha me nā mea hoʻopili e hoʻomaʻamaʻa i ke kaʻina hana a kōkua i ka hōʻoia i ka hopena kiʻekiʻe loa.
He ʻano ʻokoʻa ʻokoʻa nā pad brake piha, hoʻohana ʻia lākou i ka hoʻoponopono ʻana i nā disc brakes, nā mīkini pahu me nā pads i hoʻopili ʻia i nā pads, a i ʻole nā mīkini pahu ʻino.Ma nā kaʻa kaʻa, ʻaʻole hoʻohana ʻia ia mau mea.
Hoʻokomo ʻia nā linings friction ma nā pad brake me nā rivets (paʻa a hollow) a i ʻole ke kāpili.Hoʻohana ʻia nā rivets i nā pahu pahu, hoʻohana pinepine ʻia ke kāpili i nā pad brake disc.Hāʻawi ka hoʻohana ʻana i nā rivets i ka hiki ke hoʻololi i nā linings i ka wā e pau ai.No ka pale ʻana i ka pōʻino i ka pahu pahu a i ʻole ka disc, hana ʻia nā rivets i nā metala palupalu - aluminika a me kāna mau ʻāpana, keleawe, keleawe.
Hiki ke hoʻokomo ʻia nā mea hoʻohana mīkini a me nā mea ʻike uila ma luna o nā pale pale pahu hou.ʻO ka mea ʻike mīkini he pā i loko o ke kino o ka lining, a i ka wā e pau ai ka ʻāpana, e hoʻomaka ana e ʻoki i ka pahu a i ʻole ka disc, e hana ana i kahi kani ʻano.Ua hūnā pū ʻia ka mea ʻike uila i loko o ke kino o ka lining, i ka wā e ʻaʻahu ʻia ai, ua pani ʻia ke kaapuni (ma o kahi disk a pahu paha) a ke kukui ʻia ka hōʻailona pili ma ka dashboard.
ʻO ke koho pololei, ka hoʻololi a me ka hana ʻana o nā pale pale pale
Hoʻokomo ʻia nā linings friction i ka wā o ka hana, e emi mālie ana ko lākou mānoanoa, e alakaʻi ana i ka emi ʻana o ka hilinaʻi o nā pahu.Ma keʻano he kūlana, hoʻokahi lining e lawelawe i 15-30 tausani mau kilomita, a laila pono e hoʻololi.I nā kūlana hana paʻakikī (hoʻonui i ka lepo, ka neʻe ʻana i ka wai a me ka lepo, i ka wā e hana ai ma lalo o nā ukana kiʻekiʻe), pono e hana pinepine ʻia ka hoʻololi ʻana o nā linings.Pono e hoʻololi ʻia nā linings i ka wā e ʻaʻahu ʻia ai lākou i ka mānoanoa liʻiliʻi i ʻae ʻia - ʻo ia ka mea maʻamau ma kahi o 2-3 mm.
No ka hoʻololi ʻana, pono ia e hoʻohana i nā linings friction i loaʻa nā ana kūpono no kahi kaʻa - ka laulā, ka lōʻihi a me ka mānoanoa (e hōʻike pinepine ʻia nā ʻāpana pono āpau ma nā linings).Ma kēia hihia wale nō, e hoʻopili piha ʻia ka lining i ka pahu a i ʻole disc a e hana ʻia ka ikaika braking lawa.No ka kau ʻana i ka pā ma ka poloka, hiki iā ʻoe ke hoʻohana i nā rivets i hana ʻia i nā metala palupalu, ʻoi aku ka maikaʻi o ka hāʻawi ʻana i ka makemake i nā mea hoʻopaʻa i loko o ka pahu.Pono e kanu ʻia nā rivets i loko o ke kino o nā linings i mea e pale ai iā lākou mai ka hamo ʻana i ka pahu, i ʻole e lilo nā ʻāpana i ka lole a me ka waimaka a hiki ke hāʻule.
Pono e hoʻololi i nā linings ma nā pad brake i nā hoʻonohonoho piha, a i ʻole, i nā hihia koʻikoʻi, ʻelua ma ka huila hoʻokahi - ʻo kēia wale nō ke ala e hōʻoia ai i ka hana maʻamau o nā mīkini ʻoki.Pono e hoʻokō i ka hoʻololi ʻana e like me nā ʻōlelo aʻoaʻo no ka hoʻoponopono ʻana a me ka mālama ʻana i kahi kaʻa, inā ʻaʻole aia kahi kiʻekiʻe o ka hōʻino ʻana o nā kaʻa.
I ka hana ʻana i ke kaʻa, pono ʻoe e pale i ka overheating o nā linings, a me kā lākou pulu a me ka hoʻohaumia - ʻo kēia mau mea a pau e hōʻemi i kā lākou waiwai a hoʻonui i ka hiki ke haki.I ka wā e holo ai i loko o ka wai, pono e hoʻomaloʻo ʻia nā linings (wikiwiki i nā manawa he nui a kaomi i ka pedal brake), me ka lōʻihi o ka iho ʻana, ua ʻōlelo ʻia e hoʻohana i ka braking engine, a me nā mea ʻē aʻe. e hana hilinaʻi a palekana.
