Pistons yakha ukuba brand imoto ezahlukeneyo

Uninzi iiteknoloji idluliselwe Ushishino lweemoto of Ngini. izisombululo Kukho esetyenzisiweyo kunye iinkcukacha zithathwa nje ukuthembeka kunye ukusebenza iisampuli, ezifana Pistons zomgunyathi. Avtotehnologiya ngokusekelwe ngokusetyenziswa kwenxenye data sinxulumene ukusetyenziswa iimodeli bexhamla izigqibo iimoto ezithwala.

definition

Pistons inikezwe bushings okweqanda, ukuhamba nkqo ngaphakathi lombhobho kwaye Oluma umxube amafutha-moya. Ngokutsho iteknoloji la maqela yahlulwe cast wenza yentsimbi. Makhe sihlolisise ngokweenkcukacha.

Iimpawu yokusebenza

Le Pistons yohlobo lokuqala imvelaphi inyuselwa khona phezu izithuthi ezininzi, njengoko kakuhle azibonakalisa umsebenzi ngemihla kwaye ezaneleyo ukulungiselela iimfuno ezininzi lwabasebenzisi. Pistons yakha luyilwe ukusebenza kwi layisha phezulu, ngoko ke asetyenziswa ezemidlalo kunye neemoto nemidyarho. Oko kukuthi, isakhiwo neempawu icandelwana elinikiweyo umiselwa kusekelwe phezu kweemeko nokusebenza kwayo.

Eyona ngokunzima esebenza phezu Pistons ngexesha lokusebenza injini isici obushushu. Oku kukhokelela ekwandeni intsimbi, i-non-uniform: oko ome iqapheleka kakhulu ukuba ezimanyeneyo isikhonkwane piston kunye nezihlanganisi intonga oscillation moya asezantsi. Ngenxa yoko, qhagamshelana ngokungalinganiyo piston kunye lombhobho, ngaloo ndlela ekukhawuleziseni banxibe. Kwiimeko kakhulu, kukho ixhaphaza kwaye wakhankanya iinkcukacha uthathe, apho injini kuba ngci.

Ukongeza, ezi Pistons kuchaphazela amandla inertia yaye ingcinezelo eyenziwe yeegesi ngaphakathi njengesilinda.

kubuxhakaxhaka bokuvelisa

Nanjengoko igama layo lixela, lokuvelisa elingqukuva Pistons zobuchwepheshe ezisetyenziswa metal eyahlulayo. Sezikusetyenziso ingxubevange aluminiyam-lesilicon njengoko izinto yokuqala. Ibekwe kwi isizalo, enika seqanda. Inxalenye siyahlengahlengiswa ukuba njengesilinda. Umphetho ukwenza iwindow umphanda-kangangoko. Ukuqinisekisa kwinkcaso lobushushu eliphezulu igcwele ngaphakathi ezifakelwa steel piston termokompensiruyuschimi

Ngokwahlukileyo koko, uphose, Pistons bakhiwa eziveliswa ngokuwanyathela technology. Sebenzisa iindlela lulwelo okanye isothermal.

Kwimeko yokuqala isizalo izele etyhidiweyo kwaye deforming ngayo ngesantya elithile kunye Punch. Ngoko ukulungele preform ezikumgangatho ophezulu. ngonyango lokugqibela wenziwa zoomatshini.

Kuba isothermal bexhentsa iteknoloji usebenzisa amalungu eyenziweyo. Bona olulungiswe intonga ababandakanya i-aluminiyamu lesilicon-sisityebi, crimped ngenxa swa evumela ukuphucula ubume metal ngokususa pores. Ngaphezu koko, e matrix ndinobushushu 450 ° C kungekhonto into isitampu usebenzisa umatshini ngesanti kubunzulu baphantsi indlela isantya. Le iteknoloji sikuko isicelo isizalo umkhosi iitoni ezingama-250, lo gama kugcinwe kwithempritsha yayo kwinqanaba rhoqo. Ngenxa yoko iindawo ezikumgangatho ophezulu ngqo.

The main iparameters

Kuba ukhetho olufanelekileyo iinxalenye imoto phantsi ingqalelo parameters zabo ngamazinga kunye iimpawu injini. Ezi zilandelayo iimpawu eziphambili Pistons yakha:

1. model injini. Indlela elula yokufumana iindawo ezisekelwe injini ye lophawu, njengoko abenzi uqobo ukuvelisa iimveliso ezifana phantsi imifuziselo ezithile injini. Nangona kunjalo, khumbula ukuba kulo mzekelo, zenzelwe ukuba injini imfuyo. Oko kukuthi, ukuba utshintsha naziphi na iparameters injini, ezifana iisilinda ndidikwe, Pistons ziyilelwe ngokuba azisayi kusebenza. Emva koko akhethwa nezinye iparameters (kulo mzekelo, kuqala kwiinto zonke, kubungakanani).
2. Ubukhulu. Xa kukhethwa izinto eziyimfuneko ukuze angqamane nabo ubukhulu be yazala cylinder ngenxa yokwanda thermal.
3. The degree of ucinezelo. I-technical Ipharamitha Pistons lubonise ixabiso ethile le index, esithi zenzelwe. Ukuba injini akafuni Stock, oko kufuneka zithathelwe ingqalelo.
4. Weight. Ukubaluleka kwale parameter, wathi Pistons. Ngokubanzi, ubunzima lwabo yasezantsi; ngcono.
5. Power. I-technical Ipharamitha Pistons ibonisa amandla ubuninzi apho ukuba ukhuseleko imajini ezaneleyo. Musa ukufaka iindawo kwi injini kunye iimpawu ezinkulu njengoko umthwalo kwemfuneko kungakhokelela yokonakala zabo olukhawulezayo intshabalalo.

Umahluko evela Pistons cast

iindawo analogue ingqalelo Standard ulahliwe Pistons. Bona rhoqo usebenze iinjini eqhelekileyo, kodwa ngenxa yezizathu ezahlukeneyo ayifanelekanga ukuba isetyenziselwe kweeyunithi amandla eliphezulu-amandla. Okokuqala, ukuba ube nelitye eliphezulu. Okwesibini, i Pistons ingxubevange abe ifomu elifaneleyo ayikaphuhli. Okwesithathu, la malungu zonakeleyo ukusuka mveliso, angabi nemingxuma thaca, inclusions amazwe, bubbles, ezingabonakaliyo kwaye musa abonakale ukusetyenziswa eqhelekileyo kwiiyunithi ngamandla.

Nangona kunjalo, ukwandisa amandla kukhokelela ukunyusa imithwalo (ubushushu kunye noxinzelelo) beengxenye ezininzi isithuthi injini kakhulu. Kwiimeko ezinjalo iziphene zikhankanywe kunokukhokelela ngokuhlaziya okanye wokukhusela-kwi le piston. Oku kunokwenzeka, umzekelo, emva kokumiselwa crankshaft ne non igeza radius.

buhle

Igalelo elihle Pistons sakha kwiparameters injini kubangelwa ikakhulu ubunzima yabo. Ubunzima izinto ezinjalo nge-avareji ngaphantsi kwama-50 iigrem cast analog. Umzekelo, Pistons zomgunyathi Vaz zinika ugcino olupheleleyo ubunzima 400-600 g Oku kunciphisa imikhosi inertial ngaphakathi njengesilinda. Ngenxa yale isantya okwandileyo, kunciphisa ilahleko mechanical, kuyanda amandla. Ukongeza, umthwalo inertia kwanciphisa kwezinye izinto balo matshinana igeza lo, ezifana crankshaft, ukudibanisa iintonga kunye bushings. Oko kukuthi, isabelo sawo buyanda.

Pistons siphinde sakha kwahluka ongangokugibisela yobulukhuni enkulu. Eli nani 120-130 iiPC., Ekubeni ngenxa kunezixhobo emkhosini, yena iiyunithi 80-90.

Ngaphandle data izinto luphawulwa ngamandla aphezulu kunye ukuxhathisa lobushushu. Ngoko ke, ngokutsho uzinzo weebhayisekile thermal kunabanye lokuphosa betye ngokuphindwe 5-6. Ngenxa Pistons zomgunyathi ukumelana 2500 imijikelo ubushushu-okupholisa, lo gama 400 kuphela imodeli emkhosini.

Okwehlileyo thermal ukwanda lomlingani ukunciphisa umsantsa thermal wavumela phakathi lombhobho kunye piston ukuya 0.05-0.06 mm.

imilo

Ukunciphisa ubunzima Pistons yakha ube uhlobo ekhethekileyo. Kulo sicelo T-iprofayile aluchaphazeli ukuhamba oyile.

Ukongeza, ngenxa yokwanda thermal ezimagqagala (ikakhulu zifana kuya ezimanyeneyo pin piston), ezinye abavelisi ukuvelisa imifuziselo okweqanda, aa Incopho na ezimanyeneyo pin piston. Ngenxa yoko, ngexesha ngokushushubeza umba uba imilo setyhula, ngokungqinelana kunye imilo njengesilinda. Oku kunika a Ukufudumala angqamane omnye komnye, esasaza umthwalo ngokulinganayo phezu imiphezulu nasekunqandeni ukungena yeegesi kwi crankcase egumbini yokutsha.

ukushiyeka

Eyona ethile engundoqo ye piston kwaphunyezwa, xa kuthelekiswa ne ukubunjwa, cinga iindleko eziphezulu, yaye zombini ezi nxalenye ufakelo. Ixabiso eliphezulu kwimveliso okubangelwa Pistons xaka. Ukongeza, kuya kufuneka imali nzulu kufakelo zabo. Oku kungenxa yokuba nzima ezinjalo kufuneka uthembe iinkosi abaqeqeshiweyo kuphela, kwaye kule meko kufuna ngokufaka nje kuphela, kodwa ukuba uqwalasele iinkcukacha.

Ukongeza, kukholelwa ukuba Pistons zomgunyathi kwenza imoto nengxolo ngakumbi xa kuthelekiswa ne iindawo cast yokuqala. Nangona kunjalo, oku kuyinyaniso kuphela ukuba imoto shushu-up. Olu phawu kungenxa umahluko okuza ukwanda. Ngokusekelwe Pistons omgunyathi ukuze kwandiswe kancinci umsantsa kunye nodonga njengesilinda. Ngoko ke, lo injini iyabanda neenkcukacha ezinjalo iyangxola. Noko ke, emva kokuba ubushushu, xa Pistons ziyanatyiswa, yaye ngoko, umsantsa ubushushu lifinyele, ingxolo kudambe.

isicelo

Njengoko eziqondwa, Pistons zomgunyathi ngentla asetyenziswa injini augmented. La malungu zichaphazela iimpawu ezininzi powertrains. Bona ukwandisa zombini ukusebenza nokuthembeka.

Ukuhambisana

Ukuba nokwenzeka usebenzisa Pistons zomgunyathi endaweni elingqukuva uzimisele kakhulu features ukusetyenziswa kwezithuthi. Kuba imiqathango yokusetyenziswa ngemihla ngokwaneleyo ungamalungu Yamxuluba. analogs yakha uqobo zisenokukhupha xa iswitch injini. Yaye kulo mzekelo, ukusetyenziswa kwazo akusoloko kufanelekile.

iinkcukacha ezo zisetyenziswa ewela iinjini ezincinane. iindawo Standard ezinye iinjini ezemidlalo izibonelelo ezaneleyo ukuphucula amandla non-kakhulu. Ngoko ke, lo ixhaphakileyo iinxalenye injini enjalo Vaz (umz, Pistons zomgunyathi "Niwa" kunye Pistons omgunyathi ukuze "Ngaphambi").

La malungu zisetyenziswa kuphela iimoto. Unako ukufaka zakha Pistons kwi isithuthuthu. uhle Incam imidlalo nazo kakhulu eqhelekileyo. Ngamanye amaxesha modified kunye ngezithuthuthu eziqhelekileyo. Ngokomzekelo, ezinye iseti lwenkohliso Pistons kwi "phambene".

Imigaqo yokusebenzisa kunye neendleko

Kudla ingqalelo iinkcukacha zisetyenziswa xa ufaka le turbocharger. Ngaphezu koko, kwiimeko ezininzi, ukusetyenziswa kwazo kubalulekile ebomini injini ulondolozo, ekubeni kwandisa amaqondo kunye umthwalo workpiece, nto leyo ngokufuthi ekhokelela ukutshisa-Pistons. Pistons yakha kwiinqwelo-injini ngesiqhelo asetyenziswe khithi kunye namanye crankshaft kunye iintonga ezimilise H.

Kuyo nayiphi na imeko, ufakelo kuyimfuneko ukubonelela Ukupholisa ngesondo kunye namalungu ezantsi ezichazwe. Ukuze wenze oku, wabeka nemilomo maslorazbryzgivayuschie.

Ixabiso lwenkohliso Pistons "Niva" (iseti), umzekelo, iqala 4500 engange. Kuba ngesithuthuthu zasekhaya ukuba zibiza ngaphantsi.
