Car light alloy mavhiri:

Muindasitiri yemotokari, mavhiri alloy mavhiri anogadzirwa kubva kune alloy yealuminium kana magnesium.Alloys musanganiswa wesimbi nezvimwe zvinhu.Ivo vanowanzopa simba rakakura pamusoro pesimbi dzakachena, dzinowanzova dzakapfava uye dzakawanda ductile.Alloys ealuminium kana magnesium anowanzo kureruka kune simba rimwe chete, anopa kupisa kurinani conduction, uye anowanzo gadzira yakagadziridzwa yerunako chitarisiko pamusoro pemavhiri esimbi.Kunyangwe simbi, iyo inonyanya kushandiswa mukugadzirwa kwemavhiri, iri alloy yesimbi uye kabhoni, izwi rekuti "alloy vhiri" rinowanzo kuchengeterwa mavhiri anogadzirwa kubva kune nonferrous alloys.

Mavhiri akareruka anogona kuvandudza mabatiro nekuderedza unspring mass, achibvumira kuturika kutevera nzvimbo zvakanyanya uye nekudaro kunatsiridza kubata, zvisinei kwete ese mavhiri alloy akareruka kupfuura akaenzana nesimbi.Kuderedzwa kwehuremu hwemotokari yese kunogona kubatsirawo kuderedza kushandiswa kwemafuta.

Zvirinani kupisa conduction uye yakavhurika vhiri dhizaini inogona kubatsira kubvisa kupisa kubva kumabhureki, izvo zvinovandudza mabhureki mashandiro mune zvakanyanya kudiwa mamiriro ekutyaira uye kuderedza mukana wekuderera kwekuita kwebhureki kana kutadza nekuda kwekupisa.

Alloy mavhiri anotengwawo kuti agadzirise zvizorwa kunyangwe iwo akachipa alloys anoshandiswa kazhinji haaite corrosion.Alloys anobvumira kushandiswa kweanoyevedza asina-simbi anopedza, asi aya anoda kuvharwa nependi kana mavhiri anovhara.Kunyangwe zvakadaro akadzivirirwa mavhiri ari kushandiswa anozopedzisira atanga kuita ngura mushure memakore matatu kusvika mashanu asi kuvandudzwa kwave kuwanikwa zvakanyanya nemubhadharo.Maitiro ekugadzira anobvumirawo akaoma kunzwisisa, akashinga dhizaini.Kusiyana neizvi, mavhiri esimbi anowanzo kudzvanywa kubva pashizha resimbi, uye obva abatanidzwa pamwe chete (kazhinji achisiya mapundu asingataridzike) uye anofanirwa kuvezwa kuti asaita ngura uye/kana kuvanzwa nemavhiri anovhara/hub caps.

Mavhiri alloy anodhura kugadzira kupfuura mavhiri esimbi akajairwa, uye nekudaro kazhinji haasanganisirwe semidziyo yakajairwa, panzvimbo pacho ari kutengeswa seadd-ons kana sechikamu chemushonga unodhura.Nekudaro, mavhiri ealloy ave akanyanya kuwanda kubva 2000, ikozvino ari kupihwa pahupfumi uye subcompact mota, zvichienzaniswa nemakore gumi apfuura apo mavhiri alloy kazhinji aive asiri mafekitori sarudzo pamotokari dzisingadhure.Alloy mavhiri agara achisanganisirwa semidziyo yakajairwa pamotokari dzemhando yepamusoro-soro kana dzemitambo, dzine mavhiri makuru kana "ega" alloy mavhiri ari sarudzo.Kudhura kwemavhiri alloy kunoita kuti akwezve kune mbavha;kupikisa izvi, vagadziri vemotokari uye vatengesi vanowanzo shandisa kukiya lug nzungu izvo zvinoda kiyi yakakosha kubvisa.

Mavhiri mazhinji alloy anogadzirwa achishandisa kukanda, asi mamwe anogadzirwa.Mavhiri eForged anowanzoreruka, akasimba, asi anodhura zvakanyanya kupfuura mavhiri anokandwa.Kune mhando mbiri dzemavhiri akaumbwa: chidimbu chimwe uye modular.Modular forged mavhiri anogona kunge ane maviri- kana matatu-chidimbu dhizaini.Mavhiri akajairika ane zvidimbu zvakawanda ane mukati merimu base, rekunze rim lip uye vhiri repakati chidimbu chine maburi emalug nuts.Zvese zvikamu zvemodular vhiri zvinobatwa nemabhaudhi.Rayone KS001 ndeimwe yeanonyanya kuzivikanwa matatu-chidimbu modular forged mavhiri semuenzaniso.

Sarudzo yakakura yemavhiri alloy inowanikwa kune varidzi vemotokari vanoda kureruka, kutaridzika kutaridzika, kushoma, uye / kana mavhiri makuru pamotokari dzavo.Kunyangwe kutsiva yakajairwa vhiri resimbi uye matayi mavhiri nemavhiri alloy akareruka uye anogona kudzika mavhiri mavhiri anogona kukonzera kuwedzera kwekuita uye kubata, izvi hazvibatike kana mavhiri arikuwanda achishandiswa.Tsvagiridzo neMota uye Mutyairi yakaitwa uchishandisa sarudzo yeakasiyana saizi alloy mavhiri kubva ku15 "kusvika 21" mu (38,1cm kusvika ca. 53,34 cm) ese akashongedzerwa akafanana kugadzira uye modhi yematayi airatidza kuti zvese kukurumidza uye hupfumi hwemafuta. akatambura nemavhiri makuru.Vakataurawo kuti kugadzikana kwekutasva uye ruzha zvakakanganiswa zvakanyanya nemavhiri makuru.

Nzira dzekugadzira:

Forginginogona kuitwa neimwe kana yakawanda-nhanho nzira yekugadzira kubva kwakasiyana magnesium alloys, kazhinji AZ80, ZK60 (MA14 muRussia).Mavhiri anogadzirwa nenzira iyi anowanzo kusimba kwepamusoro uye ductility kupfuura mavhiri ealuminium, kunyange zvazvo mari yacho yakakwirira zvikuru.

High pressure die casting (HPDC).Iyi nzira inoshandisa difa rakarongwa mumuchina muhombe une simba rekuvhara zvakanyanya kusungirira dhiza yakavharwa.Magnesium yakanyungudutswa inodirwa muchubhu yekuzadza inonzi shot sleeve.Piston inosundira simbi mudhibhi nekumhanya kukuru uye nekumanikidza, iyo magnesium inoomesa uye difa rinovhurwa uye vhiri rinoburitswa.Mavhiri anogadzirwa nenzira iyi anogona kupa kudzikiswa kwemutengo uye kuvandudzwa kwekudzivirira kukora asi iwo mashoma ductile uye ane simba rakaderera nekuda kwehunhu hweHPDC.

Low pressure Die casting (LPDC).Ichi chiitiko chinowanzo shandisa simbi inofa, yakarongwa pamusoro peiyo crucible izere neyakanyungudutswa magnesium.Kazhinji kazhinji crucible inonamwa pakufa uye yakadzvanywa mweya/inovhara gasi musanganiswa inoshandiswa kumanikidza simbi yakanyungudutswa kukwidza chubhu yakaita semashanga yekuzadza mufi.Kana yakagadziriswa uchishandisa nzira dzakanakisa dzekudzidzira mavhiri eLPDC anogona kupa kuvandudzwa kweductility pamusoro peHPDC magnesium mavhiri uye chero akakanda aruminiyamu mavhiri, anoramba ari mashoma ductile pane forged magnesium.

Gravity casting.Gravity-cast magnesium mavhiri anga ari mukugadzirwa kubva kutanga kwema1920s uye anopa yakanaka ductility, uye hukama hwehukama pamusoro pezvinogona kugadzirwa nekukandwa kwealuminium.Mari yekushandisa yegiravity-cast mavhiri ari pakati pezvakachipa pane chero maitiro.Izvi zvakabvumira diki kugadzirwa kwebatch, kuchinjika mukugadzira uye nguva pfupi yekuvandudza.
