ʻO ka pūnāwai lau he pūnāwai hoʻomaha i hana ʻia me nā lau i hoʻohana pinepine ʻia i nā kaʻa huila.He lima semi-elliptical i hana ʻia mai loko mai o hoʻokahi lau a ʻoi aʻe paha, ʻo ia ke kila a i ʻole nā ʻāpana mea ʻē aʻe e wili ma lalo o ke kaomi akā hoʻi i ko lākou ʻano kumu ke hoʻohana ʻole ʻia.ʻO nā pūnāwai lau kekahi o nā mea hoʻokuʻu kahiko loa, a hoʻohana mau ʻia lākou i ka hapa nui o nā kaʻa.ʻO kekahi ʻano pūnāwai ʻo ia ka coil spring, i hoʻohana nui ʻia i nā kaʻa kaʻa.
I ka hala ʻana o ka manawa, ua ʻike ka ʻoihana kaʻa i ka hoʻololi nui ʻana i ka ʻenehana puna lau, nā mea, ke ʻano, a me ka hoʻolālā.Hiki mai ka leaf-spring suspension i nā ʻano like ʻole me nā kiko kau kau, nā ʻano, a me nā nui i hiki ke loaʻa i ka honua holoʻokoʻa.I ka manawa like, ke hele nei ka nui o ka noiʻi a me ka hoʻomohala ʻana e ʻike i nā mea ʻoi aku ka māmā i ke kila kaumaha.
E hoʻonui mau ana ka mākeke lau lau automotive i nā makahiki e hiki mai ana.Hiki ke ʻike ʻia nā helu hoʻohana ikaika ma ka mākeke honua, i wānana ʻia e hoʻonui i kēlā me kēia makahiki.ʻO nā ʻoihana ʻo Tier-1 ka mea nui i ka mākeke honua ākea no nā ʻōnaehana lau lau automotive.
I ka makahiki 2020, ua hoʻopilikia ka maʻi maʻi COVID-19 i nā ʻoihana like ʻole ma ka pae honua.Ma muli o nā kī paʻa mua a me nā pani ʻana o ka hale hana, ka mea i hōʻemi i ke kūʻai ʻana i nā kaʻa, ua loaʻa ka hopena i ka mākeke.Eia nō naʻe, i ka wā i hoʻokuʻu ʻia ai nā palena ma hope o ka maʻi maʻi, ua ʻike nui nā kaʻa mākeke lau lau o ka honua.Ua hoʻomaka ka hoʻonui ʻana o nā kūʻai kaʻa i ka hoʻomaka ʻana o ke kūlana.No ka laʻana, ua hoʻonui ka nui o nā kaʻa i hoʻopaʻa ʻia ma ʻAmelika Hui Pū ʻIa mai 12.1 miliona i 2019 a i 10.9 miliona i 2020. Eia naʻe, kūʻai aku ka lāhui i 11.5 miliona mau ʻāpana i 2021, he piʻi o 5.2 pakeneka i hoʻohālikelike ʻia i ka makahiki i hala.
ʻO ka ulu lōʻihi o ka mākeke lau lau automotive no nā kaʻa ʻoihana a me ka piʻi ʻana o ka makemake o nā mea kūʻai aku no nā kaʻa ʻoluʻolu e wānana ʻia e hoʻonui i ka noi no nā puna lau automotive.Eia kekahi, i ka ulu ʻana o ka mākeke e-commerce honua, e piʻi aʻe paha ka pono o nā kaʻa ʻoihana māmā e hoʻokō i nā pono o nā mea hana kaʻa, e hopena i ka piʻi ʻana o ka noi no nā puna lau automotive ma ka honua.Ua piʻi aʻe ka kaulana o nā kaʻa pickup no ka hoʻohana pilikino i ka US, kahi i hoʻonui ai i ka pono o nā puna lau.
E hōʻike ana ʻo ʻAsia-Pākīpika i nā manawa kūpono i nā mea hana honua o nā puna lau automotive, hāʻawi ʻia i ka hana kiʻekiʻe o ka kaʻa kalepa a Kina, a me ka ikaika o ka ulu ʻana o nā ʻoihana e like me Kina, India, Iapana, a me South Korea.ʻO ka hapa nui o nā mea hoʻolako ma ka ʻāina e ʻimi e hana i nā hopena māmā me ka hoʻohana ʻana i nā mea ʻoi aku ka maikaʻi e like me ka mea e hiki ai iā lākou ke hoʻokō i nā kūlana i hoʻonohonoho ʻia.Eia kekahi, ma muli o ko lākou māmā a me ka lōʻihi o ka lōʻihi, ke hoʻololi nei nā pūnāwai lau hui i nā puna lau maʻamau.
Kaohi Makeke:
I ka hala ʻana o ka manawa, e pōʻino ana nā pūnāwai lau kaʻa a hāʻule.Hiki ke ho'ololi ke kaumaha o ke ka'a i ka wā 'a'ole like 'ole ka sag, 'o ia paha ka mea e 'oi aku ka 'ino o ka lawelawe 'ana.Hiki ke hoʻopili ʻia ke kihi o ke axle i ka mauna e kēia.Hiki ke hana ʻia ka makani-up a me ka vibration e ka wikiwiki a me ka torque braking.Hiki i kēia ke kaupalena i ka hoʻonui ʻana i ka mākeke i ka wā i manaʻo ʻia.
ʻO ka Māhele Mākeke Leaf Spring
Ma ke ʻano
Hiki ke semi-elliptic, elliptic, parabolic, a i ʻole kekahi ʻano ʻano ʻē aʻe.Hiki ke hoʻonui ʻia ke ʻano semi-elliptic o ka puna lau kaʻa i ka helu kiʻekiʻe loa i ka wā o ka loiloi, aʻo ke ʻano parabolic i manaʻo ʻia i ke koi kiʻekiʻe loa.
Ma ka Material
Hoʻohana ʻia nā mea metala a me ka composite e hana i nā puna lau.E pili ana i ka nui a me ka waiwai, hiki ke puka mai ka metala ma ke ʻano he ʻāpana kiʻekiʻe o ka mākeke ma waena o lākou.
Ma ke Kaena Kūʻai
ʻO Aftermarket a me OEM nā ʻāpana mua ʻelua, e pili ana i ke kahawai kūʻai.Ma ke ʻano o ka nui a me ka waiwai, ua wānana ʻia ka ʻāpana OEM e ulu nui loa i ka mākeke honua.
ʻO nā kaʻa kālepa māmā, nā kaʻa kālepa nui, a me nā kaʻa kaʻa kaʻa i hoʻokomo pinepine ʻia me ka ʻenehana puna lau.Ma luna o ka manawa i manaʻo ʻia, ua manaʻo ʻia ka māhele kaʻa ʻoihana māmā e alakaʻi.
ʻIke ʻĀpana ʻĀpana ʻĀpana Laulā Lau Makeke
Ke ulu nei ka ʻoihana e-commerce ma Asia-Pacific, a ke hoʻoikaika nei i ka nui o ka ʻoihana kaʻa.Ma muli o ka hoʻonui nui ʻana o nā ʻoihana kaʻa kaʻa o Kina a me India, manaʻo ʻia ka ʻāina ʻo Asia-Pacific e hoʻonui nui i ka mākeke honua.ma muli o ka hoʻonui ʻia ʻana o nā MHCV (Medium and Heavy Commercial Vehicles) ma nā ʻoihana ulu ʻana o Asia a me ka noho ʻana o nā mea hana kaʻa kalepa e like me Tata Motors a me Toyota Motors.ʻO ka ʻāina kahi e hāʻawi ʻia ai nā puna lau i ka wā e hiki mai ana ʻo ia ʻo Asia-Pacific.
Nui nā ʻoihana o ka ʻāina e kālele ana i ka hana ʻana i nā pūnāwai lau huila no nā kaʻa uila a me nā kaʻa kalepa māmā (LCVs) ma muli o ka hōʻemi ʻana i ka paʻakikī, ka walaʻau, a me ka haʻalulu.Eia hou, ke hoʻohālikelike ʻia me nā pūnāwai lau kila o nā māka like ʻole, he 40% ka liʻiliʻi o nā puna lau hui, he 76.39 pakeneka haʻahaʻa haʻahaʻa haʻahaʻa, a he 50% ka liʻiliʻi.
ʻAʻole nui ʻo ʻAmelika ʻĀkau ma hope o ka hoʻonui ʻana, a ke neʻe nei i mua i ka mākeke honua.ʻO ke koi ʻana o nā kaʻa ʻoihana māmā, e ulu nei i ka ʻoihana kaʻa, ʻo ia kekahi o nā mea hoʻokele nui o ka ulu ʻana o ka mākeke lau lau o ka ʻāina.Hoʻokomo pū ka hoʻokele ʻāina i nā kūlana hoʻokele waiwai wahie me ka manaʻo e hōʻemi i nā hopena maikaʻi ʻole o ka hoʻomehana honua.No ka mea e hiki ai iā lākou ke mālama i nā kūlana i ʻōlelo ʻia aʻe nei, ʻo ka hapa nui o nā mea hoʻolako kaulana ma ia wahi makemake e hoʻohana i nā mea ʻokiʻoki e kūkulu i nā huahana māmā.Eia hou, ma muli o ko lākou kaumaha māmā a me ka lō'ihi o ka lō'ihi, ua kaulana nā pūnāwai lau huila a ke ho'one'e nei i nā pūnāwai lau kila ma'amau.
