He aha te pūoko crankshaft motuka?
Ko te pūoko tūnga o te toki porowhita he pūoko matua i roto i ngā miihini motuka e whakamahia ana hei kite i te tūnga, te tere o te toki porowhita me te tohu pokapū mate o runga o te piston. Ko tana tohu te kaiwhakahaere tika i te wā mura me te wā werohanga wahie, kia pai ai te mahi a te miihini, kia pumau hoki.
Mahi matua
Te kimi i te tūranga o te porowhita: Mā te nekehanga whanaunga o ngā niho kōpae tohu me te pane aukume, ka puta he tohu pāhekoheko hei whakatau i te tūranga o te piston (70° i mua i te pokapū mate o runga).
Aroturuki i te tere o te miihini: Tātaihia te nui o te wahie e rere ana, ā, āwhina i te ECU ki te whakarerekē i te nui o te weronga wahie me te koki whakamua o te mura.
Te tautuhi i te raupapatanga o te rango me te aroturuki i te korenga o te pupuhi: Ka tutuki te tautuhi i te raupapatanga o te rango mā te rerekētanga ā-wāhanga o ngā tohu pā (pēnei i te 90°), ā, ka kitea ngā āhuatanga korenga o te pupuhi.
Ngā momo noa
Youdaoplaceholder0 momo pātere aukume : Ka whakaputa i tētahi kaha hiko tauutuutu mā te whakarerekē i te papa aukume, pērā i ngā pūnaha a Nissan me Toyota.
Youdaoplaceholder0 Tātai pānga whare : Mā te kite i ngā huringa o te papa aukume mā roto i ngā huānga whare, ka puta he tohu matihiko.
Momo whakaahua-hiko Youdaoplaceholder0 : Ka whakaputa tohu mā te whakawhirinaki ki te aukati o te ara whatu, ā, he iti ake te whakamahinga.
Tauwāhi tāutanga
Mīhini tīhiera: Ko te nuinga o te wā ka tāutahia ki te whare wira rere, ki te papu tuku rānei.
Mīhini penehīni: E kitea whānuitia ana i roto i te kaituku (pērā i te pūnaha TCCS a Toyota) i te taha rānei o te wira rere.
Te whakaaturanga o te hapa
He uaua te tīmata i te mīhini, he wiri, he tū rānei.
Kua heke te penapena wahie, ā, kua hipa ake ngā tukunga i ngā paerewa.
Ko te mahi matua o te pūoko crankshaft motuka (e mōhiotia ana ko te pūoko tūranga crankshaft, ko te pūoko tere miihini rānei) ko te kite i te tūranga o te crankshaft, te tere miihini me ngā tohu o te pokapū mate o runga piston, me te tuku i ēnei raraunga ki te waeine whakahaere miihini (ECU) hei whakahaere tika i te wā mura, te wā werohanga wahie me te raupapa werohanga wahie, kia pai ai te mahi a te miihini me te pumau.
Mahi matua
Ko te pūoko o te porowhita hurihuri tētahi wāhanga matua o te pūnaha whakahaere hiko o te miihini. Ko ōna mahi matua ko:
Youdaoplaceholder0 Kitea te tūranga o te porowhita me te koki hurihuri : Aroturukihia te koki hurihuri o te porowhita i te wā tūturu, whakatauhia te tūranga motuhake o te piston i roto i te rango, me te whakarato tohu tohutoro mō te wā mura me te wā werohanga wahie ki te ECU.
Ka ine a Youdaoplaceholder0 i te tere o te miihini : Hei pūoko tere, ka whakauru i te tohu tere ki roto i te ECU hei whakarite hihiri i te rahinga werohanga wahie me te koki whakamua mura, kia kore ai e ranea te werohanga wahie, te whakaroa rānei i te mura.
Youdaoplaceholder0 Tāutuhia te tūranga o te pokapū mate o runga o te piston : Kimihia te wā e tae atu ai te piston ki te pokapū mate o runga (ina koa ko te pokapū mate o runga o te rango tuatahi), āwhina i te ECU ki te whakatutuki i te werohanga wahie raupapa me te wehewehe raupapa rango, me te whakarite kia tika te raupapa mahi o ia rango.
Ka tautoko a Youdaoplaceholder0 i te mana āwhina: ka whai wāhi ki ngā pūnaha iti pēnei i te whakahaere tere mangere me te whakahaere mimiti wahie, ā, ka whakatau i te hē o te mura o te miihini mā te aroturuki i te piki me te heke o te koki o te toki crankshaft, te whakapai ake i te pai o te mura me te whakaiti i ngā tukunga.
Te kaupapa mahi me ngā momo
Ka tutuki i ngā pūoko porowhita ā-ringa ā rātou mahi mā te hurihanga tohu ā-tinana. Ko ngā momo noa ko:
Momo pāorooro aukume Youdaoplaceholder0 : Ka whakaputa i tētahi tohu ngaru sinusoidal mā te whakaoho i tētahi panonitanga o te papa aukume mā roto i tētahi kōpae tohu. He iti te utu engari he ngoikore ki te pokanoa.
Momo whare Youdaoplaceholder0 : Ka tukuna ngā tohu ngaru tapawhā mā te mata o te pūwhakaoho, me whai pūtake hiko o waho, ā, he pumau te tohu putanga, ā, kāore e pāngia e te tere hurihuri.
Momo hiko whakaahua Youdaoplaceholder0 : Ka whakaputahia te ngaohiko pāoro mā te tuku mā roto i te kōhao mārama, he tino tika engari he ngāwari te pāngia e ngā paru hinu.
Me mahi tahi ngā momo katoa me te pūoko tūnga camshaft kia pai ai te hono o ngā tohu.
Pānga hapa
Ka taea e ngā āhuatanga rerekē o te pūoko te arahi ki:
Ina kā te rama hapa o te miihini, he tohu tēnei mō te uaua ki te tīmata, te kore e ranea te mana, te kore rānei e taea te tīmata.
Ka whakaitihia te penapena wahie, ka whakapiki ake hoki i ngā tukunga ina hē te wā mura me te wā weronga wahie.
Ko ngā tino take o ngā hapa ko te tawhito o te ara iahiko, te paru o ngā pūoko, te kore rānei e tika te whakaurunga o te āputa (ko te āputa paerewa he 0.2-0.4mm).
