Pistons ( "Ngaphambi"): iintlobo, ukhetho, ncomo

Kwakulungiswa emva kokuba ukusilela injini ixesha ibhanti kunokwenzeka, kodwa ke kuya kufuneka ukuba achithe eli umgudu, ixesha nemali. Ngoko ke, abanini imoto awalindi de breaks umtya, kwaye Pistons ukudibana semigudu, yaye ngoko nangoko ukuseka ezinye Pistons ekhuselweyo. "Priora" namacandelo efanayo isebenza ngokufanayo kunye mveliso. Kodwa ingozi breakage ngenxa breakage ixesha ibhanti kuyehla ukya ekupheleni nya.

Ngoku kukho abenzi eziliqela avelisa iinxalenye injini kuquka Pistons. "Priora" zigqityiwe kunye nemveliso evela Russian "STK" iinkampani "STI" yaye "AVTRAMAT" evela kumenzi Ukrainian. Makhe sibone ukuba yintoni ezi mveliso.

ulwazi jikelele

A piston enjinini yokuvutha lwangaphakathi eyenzelwe nokudlulisela amandla ojikelezayo ukuya crankshaft. Le amandla eveliswe yi ukutshiswa mxube. Xa umxube edubulayo emoyeni, amafutha, ukwandiswa igesi kwenzeka. press lwakutshanje phezu komhlaba inxalenye kwaye akuyekanga ukutyhala. Ukusebenza, umphezulu piston lifumana imithwalo eliphezulu thermal. Xi Motors "Priority 'inokuba ukuya kutsho kwinqanaba bar 65-80.

Ngexesha "Okubaluleke kakhulu" ke Pistons umsebenzi kunye periodicity ethile senyuka saya ngesantya-100 km / h, uze emva koko yehla yaya kwi zero, amaza zokusebenza ngo-6000 ISityhi. / Min ngu 200 Hz. Xa combusted umxube amafutha-moya egumbini zokufudumeza nga degrees 1800-2660. Oku izihlandlo eziliqela ngaphezu lobushushu apho metal linyibilike. Ngenxa yoko, lancitshiswa amandla ingxubevange. Umzimba piston ukuba ombane ezahlukeneyo ngenxa uyothuka lobushushu ngesiquphe kananjalo wongezelela ombane ukusuka yoxinzelelo inertia-nemodareyitha xa nokukhawulezisa kwi iinkqubo eliphezulu ezitsho.

device

Ukuze igeza ibandla ezisenokusebenza nemvelo ezintsonkothileyo, le nto kufuneka ukukhanya banxibe ukumelana. Ingxubevange has a conductivity eliphezulu thermal - inikwe kule isantya Ukupholisa ngexesha ukufudumeza.

Umphezulu engaphandle abunjwe ngendlela yokuba engazange yenzeke jamming iindawo ngaphakathi egumbini yokutsha. EGaza akufuneki iwele crankcase. Ngenxa umahluko iqondo lobushushu ilungu piston isithsaba kunye isondo senziwe enembonakalo ifatyi. Ngoko ke, ukuba iyaneliseka zonke iimfuno.

Ukuze kubuyekezelwe deformation umphetho kule nkqubo, indlela wenziwa-ekuthiwa "protivoellipsom". Inxalenye enkulu kukuba nkqo ukuba ezimanyeneyo emngxunyeni ze ubhontsi. Inxalenye nakumphezulu piston - intloko ebizwa njalo-. It has a ezantsi kunye emseleni okhethekileyo. Zicwangcisa O-amakhonkco. Kwintloko piston unako ukumelana imithwalo eziphakamileyo, ukuba isicelo yayisoma special zokhuselo.

Groove for emakhonkcweni piston kwenziwa kwindawo engile okungephi. Oku kuqinisekisa ukuma iikona zangaphandle amakhonkco ngaphezulu zasekhaya. Nomakhi kuthintela groove yecandelo cross zithambekele phantsi kwiqondo lobushushu eliphezulu. Asiyiyo iimpawu yokugqibela, nto leyo Pistons ezahlukeneyo. "Ngaphambi" lixhotyiswe izinto ezinjalo, leyo "slip" kwigumbi yokutsha. Ukuza kuthi ga ngoku, kumphezulu wazo yokusebenza ehlanganiswa koololiwe ezizodwa. Ukuze ngcono inxalenye olubengezelayo, isicelo Ipeyinti, nto leyo iya kuphelelwa xa ibaleka. Idla ngokuba phosphated tin kuqamba. Kule daka kuphungula kukuvela imikrwelo ngexesha lokulayita. izinto Anti-zochuku kuhlala phezu piston ngonaphakade. abakukhusela Bona ngokuhlaziya umsebenzi wenxalenye kunye ukhukhuliseko.

ekuvelisweni isondo piston iphathwa kunye abaqingqi abo ezizodwa ukwenza micro-isiqabu. Ekubeni ioli igcinwe ngcono phezu komhlaba, nto leyo eye yanciphisa iimpikiswano zochuku phezu Pistons. "Priora" ukugcina imithwalo enzima phezu igeza. Zonke ezi parameters bahambelana nalaa mabinzana Pistons efanayo party. Ukuveliswa "STK" iyahluka ubunzima enkulu - ncomo inqaku. Ewe inzima ngaphezu kwazo zonke ezinye iimodeli.

Izizathu ngotshintsho

Apha yonke into ngamnye kakhulu. Abaqhubi athi ukuba ukuthobela ngokupheleleyo yonke imimiselo malunga nokugcinwa, ekhwele imoto "Lada Priora" iindawo evela kumenzi sokuqala, okanye oogxa ezikumgangatho ophezulu, injini akasoze phantsi kuwe. Yonke into iza kusebenza ngokwesiqhelo. Kodwa wonke umntu ufuna ukugcina imali kumalungu replacement okanye wenze wasele "ngumba". Oku kuphakamisa imibuzo. Umzekelo, ukuba ugcine phezu ixesha, ngokumisela izileyi ephantsi ezisemgangathweni kunye nebhanti, ubude bomtya utshintsho liyehla kancinci. Umzekelo, ibhanti ixesha oqhelekileyo kufuneka itshintshwe rhoqo km 50,000. On non-original abaza kuzisebenzisa ungachitha uhambo ukuya ku amawaka-10 km.

Pistons "STI"

"STI" - inkampani Togliatti. Le Pistons zenziwa ubugcisa eshushu-inki. Xa sihlalutya ingxelo kubo bonke abo baye sele wathenga imoto "Lada Priora" Amalungu eli lophawu, ungabona ukuba lincipha kakhulu ngendlela injini. Oku kuchazwe into yokuba xa kuthelekiswa imveliso "STC" yaye "AVTRAMAT" kwiindawo "STI" ucinezelo asezantsi ratio. Eli gumbi yokutsha na indawo enkulu ngenxa anzongonzongo kakhulu kwesampulu vana.

Ukubunjwa ingxubevange umxholo lesilicon lifinyele. Oku kuchaphazela iimpawu ukomelela iinxalenye phantsi kwemithwalo eliphezulu thermal. Isixa-mali yancitshiswa nickel yenza iinkcukacha resource ngezantsi. Phantsi bobubi zingentla ezi Pistons abe ixabiso eliphezulu. Kodwa imveliso yakha enye evela kwinkampani "STI" balahlekelwa ncakasana ezinye iibrand. AVTRAMAT Pistons ' "(" Priora "zinabantu nabo) bayiswele aba neengxaki, kwakunye" STC ". Noko ke, kwakukho amatyala kophuke ibhanti ezimotweni nezi iindlela.

"AVTRAMAT"

Kuyinxalenye imvelaphi Ukrainian. Le Pistons zenziwa kwi kwisityalo eKharkov. Iinkcukacha senziwa ngokwenza. Yenza ingxubevange uphinda ukuba iindawo yokuqala nanceba. Vaz mveliso zebanga Pistons nazo ngokuphindaphindiweyo. Kodwa ngokungafaniyo original, isiqalelo Ukrainian unalo isampuli enzulu. Oku kwenza ukuba a lot of amancedo phezu kwento umgangatho, ukuba ibhanti ixesha waphula off. Ngokumalunga iqondo ucinezelo, iye ayitshintshanga. Ngoko ke, ukuba ufake ezi mveliso kwi iimpawu kumandla injini akuyi kubakho umahluko obonakalayo.

Ngenxa yokuba isampuli yandisa landa indawo lwegumbi yokutsha kancinci, ukusebenza kufuneka ibe ngaphantsi kwe iindawo rhoqo kakhulu. Nangona kunjalo, la manani zahlukile kancinci. Ngenxa yoko, inani yi 53,2 cm ² 53,3 ukuze cm original ² "AVTRAMAT". Ukuziqhelisa, zako azikaqapheleki. Kukho enye inzuzo ukuba ezi zezona Pistons. "Priora" (ixabiso izinto kumaxesha 3 ngaphantsi - 2000 engange, ngaphezu iimveliso ukusuka kwi "STI" - phantse 7000) apha enkonzweni malini kangako, ukuba usebenzisa le mveliso.

"STK"

La malungu ziveliswa ngokusekelwe lweshishini in Samara. Iinkcukacha kusebenza akukho yahlukile AVTRAMAT imveliso ' ". Umahluko Ubunzima piston. Ngenxa ubunzima ephakamileyo kunciphisa nokukhawulezisa okuhambisa isithuthi. Kwakhona, "STK" Pistons amanani aphezulu.

Iinzuzo ukufaka Pistons likaxakeka

Elements zila phantsi kwemithambo singapheli kakhulu. Nokuba elinye ixesha ibhanti kwentloko camshaft kunye neevalvu nje ziya ngumkhenkce endaweni. Le piston uya phantsi ngenxa crankshaft, yaye akukho nto imbi eza kwenzeka. Valve em- emseleni qamba them. Okulandelayo, umnini kuya kufuneka ukuba azigxothe imoto enkonzweni, apho iingcali uya kubuyisela elawula ixesha. Oku a plus enkulu.

Qaphela ukuba ukuba ezi vee phezu Pistons hayi, ngenxa yomnini umsantsa ibhanti baya kuzifumana ukulungiswa kakhulu. Ngokubuyisela i yiya ngqo Pistons kunye izivingco, kwakunye Shiny camshaft. Iindleko zokusilungisa onjalo aqala-30 amawaka engange. Ngoko kuyimfuneko ukuba ufake Pistons "STK" okanye ezifana. Groove ukonga imali.

bendlela

Ukuba piston kukuba ube lula (kangangoko kunokwenzeka), uze udibanise injini ukuya emandleni. Kuyenzeka ukuba kuzuzwe ukukhula iimpawu olutshintshayo 5-7%. Pistons ukukhanya zila akayi igama. Ukuze wenze umngxuma phezulu inxalenye kufuneka ukuba udonga ngokwaneleyo zamafu. Oku kwenza kube nzima ngenxa yoko amandla ilahlekileyo.

Ngaphezu koko, ezi vee ukutshintsha ucinezelo umxube ezinokutsha. Ichaphazela kananjalo lugxile yeyunithi yamandla. Ukuba azihlanganisele zonke it up, ngoko ufakelo iindawo ezinjalo injini ezilahlekileyo abo efanayo-5% of amandla. Kuba injini 150 eelitha. a. Oku 10.5 "amahashe". Enye nokubi - amafutha aphezulu. Vaz Pistons Ubukhulu ziyafana-mveliso, kodwa ngeendleko vee kwandisa umthamo lwegumbi yokutsha, nokuba kancinane kuphela. Ekugqibeleni, ngenxa yokwanda imithamo uyawa ucinezelo. Kwakhona ngokwandisa detonation.

isiphelo

Ngokuba zonke iintsilelo abaqhubi beemoto nangoku ukuseka Pistons ityala kunye emathambekeni. Oku kukuvumela ukuba ukukhusela motor xa kukho ukusilela ixesha ibhanti. Kuba abaqhubi bakholelwa ukuba Pistons best "Priora" - a imveliso "AVTRAMAT". Baye intengo engcono, ubunzima kunye nokusebenza.
