ʻO ka pūnāwai lau mahiʻai kaumaha no ka trailer tractor - ʻO ka pūnāwai hoʻomaha ʻāpana kaʻa ikaika kiʻekiʻe no ka mea hōʻiliʻili hui
He puna lau kōkua kiʻekiʻe kēia huahana i hoʻolālā kūikawā ʻia no nā mīkini mahiʻai hou. He mea elastic koʻikoʻi ia i loko o nā ʻōnaehana hoʻokuʻu a me nā ʻōnaehana cushioning o nā tractors mahiʻai, nā mīkini ʻohiʻohi, nā mea lūlū, a me nā lako halihali kahua. Ua ʻōwili pololei ʻia mai ke kila puna hana kiʻekiʻe (e like me 60Si2Mn, 50CrVA, a pēlā aku), nona ka ikaika luhi maikaʻi loa, ka palena elastic kiʻekiʻe, a me ke kūpaʻa maikaʻi loa i ka wā. Hiki iā ia ke mālama i nā waiwai mechanical paʻa i ka wā lōʻihi ma lalo o nā ʻano hana kahua paʻakikī me ke alapine kiʻekiʻe, ka ukana kaumaha, a me ka hopena nui.
Hāʻawi ka ʻano huahana i nā hui pū ʻana o ka puna lau like ʻole, me ka ʻāpana keʻa mau, ka ʻāpana keʻa loli, a me ka parabolic, i hana ʻia no ka wahi hoʻokomo a me nā koi koʻikoʻi o nā mea hana mahiʻai like ʻole. Hoʻopili paʻa ʻia kēlā me kēia puna lau me kahi bolt waena a me kahi ʻūmiʻi hoʻihoʻi. Hoʻomaʻamaʻa ʻia ka ʻili me ka pahū pana koʻikoʻi, ka peening pana i hoʻoikaika ʻia, a me kahi uhi anti-corrosion (epoxy primer + polyurethane topcoat), e hoʻopau pono ana i nā micro-cracks mua a hoʻomaikaʻi i ke kūpaʻa ʻana i ka corrosion a me ke kūpaʻa ʻana i ka hopena pōhaku. Hōʻoia ka ʻano hopena i hoʻomaikaʻi ʻia i ka neʻe mālie o ka puna lau i ka wā o ka hoʻopili ʻana a me ka rebound, e hōʻemi ana i ka friction ma waena o ka lau a me ka walaʻau maʻamau.
Ma ke ʻano o ka hana, hiki i ka pūnāwai lau ke omo pono i ka ikehu hopena mai nā undulations honua, nā loli kaumaha koke a me ke kū'ē ʻana o ka hana, e hōʻemi nui ana i ka hoʻoili haʻalulu i ka mōlina a me ke kaʻa, a laila e pale ana i nā ʻāpana hydraulic kikoʻī, ka ʻōnaehana hoʻoili a me nā mea ʻike, a hoʻolōʻihi i ke ola lawelawe o ka mīkini holoʻokoʻa.
ʻO kona kākoʻo paʻa e hōʻoiaʻiʻo ana e mālama nā mea hana mahiʻai i ka hohonu hana i hoʻonohonoho ʻia a me ke kūlana pae ʻoiai ma lalo o nā kūlana ʻāina paʻakikī, e hoʻomaikaʻi ana i ka like a me ka pono o ka lūlū ʻana, ka mahi ʻana, a me ka ʻohi ʻana. Ke hoʻohālikelike ʻia me nā mea pale rubber a polyurethane paha, he kūpaʻa ka wai wela o nā puna lau metala, kūpaʻa i ka ʻaila, a kūpaʻa i ka ozone. Hōʻike lākou i nā loli paʻakikī liʻiliʻi i loko o ka pae mahana o -40°C a i 120°C, ʻaʻole hiki ke hoʻololi mau ʻia, a he hiki ke hōʻike i ka hāʻule ʻana (ka laha lohi o ka māwae), e hoʻomaʻamaʻa ana i nā nānā maʻamau.
Uhi kā mākou laina huahana i nā nui pani o ka mea hana lako kumu (OEM) no nā lama mīkini mahiʻai nui (John Deere, Case New Holland, Kubota, YTO Group, a pēlā aku), a hāʻawi pū mākou i nā huahana i hana ʻia e hoʻokō i nā koi ukana kikoʻī, ke kiʻekiʻe arc, a me ka paʻakikī. Loaʻa i kēlā me kēia pūʻulu ka ʻike ʻana i nā hemahema 100% a me ka hoʻāʻo luhi bench (≥200,000 mau pōʻaiapuni me ka ʻole o ka haki ʻana), a hāʻawi ʻia kahi hōʻike hoʻāʻo. He kūpono ke kau ʻana, me ka hoʻopaʻa pololei ʻana i ka bolt, a ʻaʻole pinepine ka mālama ʻana (e hoʻopili wale i ka lubricant i kēlā me kēia manawa). ʻO ke koho ʻana i kēia mau pūnāwai lau e like me ka hoʻololi ʻana i ka "shock-absorbing spine" o kāu mīkini mahiʻai, e hōʻoiaʻiʻo ana i ka hana pono i nā kūlana aniau āpau.
