Piston titoa hoki rama motokā rerekē

E rave rahi o te hangarau whakawhiti ki te ahumahi automotive o Motorsport. E whakaaro He rongoā whakamahia me ngā taipitopito rite te tika, me te mahi o nga tauira, pērā i piston titoa. Avtotehnologiya i runga i te whakamahi o ngā wāhanga o te raraunga pā ana ki te whakamahi o tauira e takaro whakatau i waka harangotengote.

whakamāramatanga

E te aroaro Pistons bushings porotītaha, neke poutū roto te puoto me kokopi ana te ranunga wahie-rangi. E ai ki te hangarau kei te wehea enei wahi ki maka, me te mahi rino. Kia titiro tatou ratou i roto i ngā kōrero.

Āhuatanga o te mahi

eke nga Pistons o te momo tuatahi kei runga te nuinga o waka, kia rite ki te hunga pai ratou faaite mai ratou i roto i te mahi ia rā, me te he rawaka mō ngā hiahia te nuinga o ngā kaiwhakamahi '. E hangaia piston titoa ki te mahi i pikaunga tiketike, na kua whakamahia ratou i runga i hākinakina me waka hōiho. E ko, whakaritea te hanganga me ngā āhuatanga o te wae i homai te hāngai i runga i nga tikanga o tona mahi.

Ko te tino inarā mahi i runga i nga Pistons i roto i tauwehe mahi pūkaha he pāmahana. arata'i te reira i ki te roha o te whakarewa, te kākahu-kore: ko reira whakarara atu korerotia ki te tuaka o te titi kōkeke me te raro honotanga rererangi tokotoko oscillation. Ka rite ki te hua, whakapā pāhiwihiwi o te kōkeke ki te rango, reira tere i te kākahu. I roto i te wā tino, i reira e heahea a whakahuatia kōrero hopu, ai he piri te pūkaha.

I tua atu, pā te Pistons te kaha o tūpuku me te pēhanga i hanga e te haurehu roto te puoto.

hangarau production

Ka rite ki titau te ingoa, mo te hanga o te hangarau maka piston whakamahia makanga whakarewa. I roto i te whakamahi i te koranu konumohe-silicon rite te rauemi tīmatanga. Kei te whakanohoia te reira i roto i te kopu, hoatu he āhua porotītaha. Kei te whakaritea te wahi mo te puoto. Pito kia tino pai oko-ahuahu. Ki te whakarite i te ātete ki te pāmahana teitei tonu te roto te fakahū maitai kōkeke termokompensiruyuschimi

I roto i te rerekē, whakaputaina maka, titoa piston e takahi hangarau. Hoatu tikanga wai isothermal ranei.

I roto i te take tuatahi ki tonu te kopu i te maitai whakarewa, me te deforming reira i te tetahi tere ki te tokua. Ko te kupu rite preform-kounga tiketike. kawea Ko tōna maimoatanga whakamutunga i roto mihini.

Hoki isothermal takahi hangarau mā te whakamahi i ngā wāhanga preformed. Kua rite ratou i te tokotoko arā o te konumohe silicon-taonga, crimped roto i te mate e taea ki te whakapai ake i te hanganga o te whakarewa mā te tango i te kōputaputa. I tua atu, i roto i te kopu wera ki te 450 ° C te pātea takatakahia te whakamahi i te press waipēhi tikanga tere. Kei tēnei hangarau i roto i te tono ki te kopu i te kaha o 250 taranata, i te pupuri i tona pāmahana i te taumata tamau. Ko te hua ko te wahi-kounga teitei pau.

Ko te tawhā matua

Hoki te whiriwhiri tika o nga wahi i runga i te motokā i raro i whakaaro fakafekau'aki ratou tawhā ki te āhuatanga pūkaha. He āhuatanga matua o piston titoa te whai ake:

1. tauira Engine. Ko te huarahi māmā ki te kitea ngā wāhanga e hāngai ana i runga i te pūkaha o te waitohu, rite kaiwhakanao nuinga hua taua hua i raro i etahi tauira pūkaha. Heoi, kia mau i roto i te ngakau e i roto i tenei take, kua hangaia e ratou mo engines kararehe. Ko, ki te huri koe i tetahi o nga tawhā pūkaha, pērā i ipurau hōhā, kei te hangaia piston hoki e kore e mahi i te reira. Na e whiriwhiria e ratou e te tahi atu tawhā (i roto i tenei take, te tuatahi o te katoa, i runga i te rahi).
2. Rahi. A, no te tīpako tūemi e tika ana ki te correlate ratou ki te diameter o te whanau puoto i roto i te tirohanga o ngāwhā roha.
3. Ko te tohu o te kōpeketanga. Ko te tawhā hangarau o nga Pistons tohua uara motuhake o tenei taupū mo e e te tikanga e ratou. Ki te kore e te pūkaha Stock, hoki me whakaaro reira.
4. Taumaha. Ko te hiranga o tenei tawhā, ka mea atu piston. I roto i te whānui, i te raro ratou taimaha, te pai.
5. Power. Ko te tawhā hangarau o nga Pistons tohu te mana mōrahi ki e te hunga ratou rawaka tawhē haumaru. Kaua e tāuta wāhanga i runga i te pūkaha ki te āhuatanga nui rite te kawenga i te taikaha kia arahi ki to ratou kākahu tere, me te whakangaromanga.

Rerekētanga i te Pistons maka

E maka orotahi whakaaro wāhanga Paerewa piston. mahi ratou wā i runga i engines paerewa, engari e kore hoki ngā take e tika ana mō wae te mana te mana-tiketike. Tuatahi, E ratou he taimaha tiketike. Tuarua, ko te Pistons koranu i puka suboptimal. A toru, e hapa i te wheketere, kōwhao aroaro, inclusions ke, mirumiru, e he e kitea, me te kore e kitea i roto i te whakamahi noa i roto i ngā wae mana paerewa enei wahi.

Heoi, te whakanui ake te mana arata'i ki te whakanui ake pikaunga (pāmahana me te pēhanga) mo maha āhuatanga o te waka matua pūkaha. I roto i taua mau huru e nehenehe e hē whakahuatia arahi ki hangai tahu-i roto i o te kōkeke ranei. kia puta tenei, hei tauira, i muri i te tāutanga o te kawau hake ki he pūtoro ratchet kore.

painga

Ko te whai hua o piston titoa i roto i nga tawhā pūkaha, ko te matua e tika ana ki to ratou taimaha iti. Ko te taimaha o taua tūemi i runga i toharite iti iho i te 50 karamu o maka tairitenga. Hei tauira, piston titoa Vaz whakarato oti ora o taimaha 400-600 g whakaiti tenei i nga ope inertial i roto i te puoto. Ka rite ki te hua o tenei tere nui ake, heke parekura aunoa, te piki te kaha. I tua atu, i te kawenga tūpuku iti i runga i te tahi atu āhuatanga o te huarahi ratchet, pērā i te kawau hake, tūhono rakau me bushings. Ko, Kei te piki haere ona wahi.

rerekē piston titoa hoki i maka pakeke nui. Tenei ahua, ko te 120-130 RW., Te mea hoki ritenga harangotengote, ko ia 80-90 wae.

Haunga raraunga e āhuatanga e kaha nui, me te ātete ki te pāmahana tūemi. Ko te kupu, kia rite ki te pūmautanga pahikara waiariki e teitei ki te maka ritenga e 5-6 wā. Ngā mihi ki tenei Pistons titoa te tu 2500 huringa whakawera-meangiti, i 400 anake tauira harangotengote.

Heke whakarea roha waiariki ki te whakaiti waiariki āputa i whakaaetia i waenganui i te puoto me te kōkeke ake ki 0.05-0.06 mm.

āhua

Ki te whakaiti i te taimaha Pistons titoa e whai he puka motuhake. I roto i tenei tono e kore e T-kōtaha pā te rere hinu.

I tua atu, i runga i te pūtake o te roha waiariki pāhiwihiwi (te nuinga faitatau ki te tuaka o te titi kōkeke), hua ētahi o ngā kaihanga tauira porotītaha, hāngai ki te tuaka o te titi kōkeke. Ko te kupu, i roto i te whakawera i te tūemi riro te āhua porowhita, i runga i te āhua o te rango. E whakarato ana tēnei i te snug pai ratou ki tetahi ki tetahi, hei tuwha i te kawenga whakanoho iho ki runga ki nga papa, me te whāiti te tomo ki o ngā haurehu ki te crankcase i te ruma ngingiha.

hapehape

Ko te drawback matua o te kōkeke titoa, rite whakaritea ki whakarewa, whakaaro te utu tiketike, a e rua nga wahi, me te tāuta. Ko te utu nui o te hanga meinga e piston whīwhiwhi. I tua atu, ka whai i te reira ki te haumi i maite i roto i to ratou tāutanga. Ko tenei no te mea kia whakawhirinaki taua mahi uaua nga rangatira ngaio anake, a i roto i tenei take titau te tāuta kore anake, engari ano hoki ki te whakarite i te kōrero.

I tua atu, kua whakapono ai e nga Pistons titoa hanga te motokā ngangau ake i roto i rite ki te wahi maka taketake. Heoi, ko te pono tenei anake hoki te motokā wera-ake. Tēnei āhuatanga he tika ki ngā rerekētanga i roto i te tau whakarea roha. I runga i te pūtake o Pistons titoa ki te whakapiki ake i paku te āputa ki te taiepa puoto. Na reira, he makariri te pūkaha ki taua kōrero e rahi. Heoi, i muri i te whakawera, ka e atu nga Pistons, a reira, heke te āputa pāmahana te, subsides te reo.

tono

Ka rite ki matau i te i runga ake, Pistons titoa whakamahia ki engines whakanuia. Enei wahi pānga maha āhuatanga o powertrains. whakanui i ratou e rua mahi, me te tika.

topicality

Ko te whai huanga o te whakamahi i piston titoa hei utu o te maka takoto matua āhuatanga whakamahi waka. Hoki nga tikanga o te whakamahi ia rā nui o te maka wahi. analogs titoa e te nuinga whakaturia ka te kita pūkaha. A ara i roto i tenei take, e kore ratou whakamahi he tika tonu.

Kei te maha peheé kōrero e whakamahia ana i roto i whiti i te motors iti. wahi Paerewa etahi motors hākinakina i rawaka ngā rauemi ki te whakapai ake i te mana kore-tino. Na reira, ko te tino noa wahi taua engine Vaz (hei tauira, piston titoa "Niwa" me piston titoa ki "mua").

E whakamahia ēnei wahi e kore anake hoki waka. Ka taea e koe te tāuta kāore titoa piston i runga i te motopaika. He tino noa hoki upa i tauira hākinakina. I te tahi taime whakarerekē me huira noa. Hei tauira, titoa etahi huinga piston i runga i te "Ural".

Ngaahi Tefito'i Mo'oni o whakamahi me te utu

E mea pinepine whakaaro nga kōrero e whakamahia ana ina tāuta te turbocharger. Ano, i roto i te maha ngā take, mea faufaa no te ora engine tiaki ratou te whakamahi, mai faarahi te reira i te pāmahana me te kawenga i runga i te workpiece, e maha arata'i ki tahu-piston. piston titoa matangirua-engine tikanga whakamahia i roto i te kete, me te tahi atu kawau hake me tokotoko H-āhua.

I roto i tetahi take, he tika tāutanga ki te whakarato tautauā o te pito me wahi raro whakaahuatia. Ki te mahi i tenei, whakaturia nozzles maslorazbryzgivayuschie.

Ko te utu o titoa piston "Niva" (huinga), hei tauira, tīmata i 4500 moni. Hoki te motopaika motu utu ratou iti.
