Kuti tigadzire motokari, tinoda zvinhu zvakawanda zvakasiyana-siyana zvakadai semidziyo yesimbi, simbi isina-ferrous, zvinhu zvinosanganiswa, girazi, rabha, nezvimwewo.
Zvinotarisirwa kuzvidavirira
Kana zvasvika ku65% -85% yehuremu hwemotokari pachayo, zvisinei kuti iganda rekunze remota kana moyo wayo, muviri wesimbi wesimbi unogona kuonekwa kwese kwese.
film.
Motokari simbi inonyanya kukamurwa muzvikamu zviviri:
Imwe isimbi yemotokari, iyo inoumba goko rekunze uye skeleton yemotokari; imwe yacho imotokari matayi goridhe structural simbi, iyo inoumba motokari injini
Muchina, kutapurirana
The core material of dynamic system, suspension system, etc. Tevere, tinokupa sumo yakadzama.
1. Simbi yemuviri wemotokari
Ngatitangei kutarisa simbi yemotokari bodywork. Muviri unotakura mutoro, muviri wese muviri mumwe, simbi inoumba skeleton yake,
Uye injini, kutapurirana hurongwa, mberi uye kumashure kuturika uye zvimwe zvinoriumba
Vanoungana pane iyi furemu.
1. Simbi yepaneru yekunze yemuviri wemotokari
Simbi yemotokari muviri ekunze mapaneru anonyanya kushandiswa kugadzira kumberi, kumashure, kuruboshwe uye kurudyi gonhi ekunze mapaneru, injini hood ekunze mapaneru, trunk lid ekunze mapaneru uye zvimwe zvikamu. Zvinofanira
Ane chimiro chakanaka,
Corrosion resistance, dent resistance uye yakanaka yemagetsi weldability. Iyo yekunze pani yemuviri wemotokari inonyanya kuputirwa nendiro kuti isangane nezvinoda-anti-corrosion.
Kuti uvandudze kupikisa kwedent, kubika simbi yakaoma, yakakwirira-simba
KANA simbi uye yakakwirira formability inotonhora-yakakungurutswa annealed dual-phase simbi (yakadai seDP450). Multi-chinangwa kupisa kwemahwendefa akavharidzirwa
Pepa rakagadzirwa, rinopisa-dhip galvanized iron sheet, electro-galvanized sheet, electro-galvanized-nickel sheet, nezvimwe.
2. Simbi yemuviri wemukati panel
Kuburikidza nepanera rekunze remota, isu tinogona kuona kuti chimiro chezvikamu zvemukati wemuviri wemotokari zvakanyanya kuomarara, izvo zvinoda simbi kuti mukati memukati memuviri wemotokari ive nawo.
Yepamusoro formability uye yakadzika yekudhirowa kuita, saka mota
Iyo ndiro yemukati yemuviri inonyanya kugadzirwa neIF simbi ine yakanakisa stamping kuumbwa uye yakadzika-kudhirowa kuita, uye shoma shoma yepamusoro-simba IF simbi inoshandiswa.
Izvo zvinodiwa zvekuisa zvakafanana neyekunze kwendiro.
3. Chimiro chemuviri wemotokari
Kuwedzera mukati, tinogona kuona chimiro chemuviri wemotokari. Izvo zvine hukama zvakanyanya nekuchengetedza uye kureruka kwemotokari. nokuti
Iyi sarudzo yezvinhu inoda zvose simba guru uye plastiki yakakwirira. Chekutanga
Yakakwirira-yakasimba simbi (AHSS) ine yakanaka yakasimba yakasimba yepurasitiki bonding uye yakanaka kudhumhana
Hunhu uye hupenyu hwekuneta kwepamusoro hunonyanya kushandiswa muzvikamu zvemuviri. Semuenzaniso, iri mukati
Mafuremu ekumberi nekumashure mabumper uye zvikamu zvakakosha zvakaita seA-mbiru uye B-mbiru
Yakave yakashandiswa zvakanyanya, kana paine kukanganisa, kunyanya kumberi uye kudivi kukanganisa, inogona kunyatso kudzikisa kutyaira
Deformation yekabhini kuchengetedza vatyairi nevafambi
Safety. Kusimba kwepamusoro-soro kwemotokari kunosanganisira mbiri-chikamu simbi, martensitic simbi, chikamu shanduko induced plasticity simbi, duplex simbi, uye quenched ductile simbi.
2. Alloy structural simbi yemotokari
Kuziva simbi inoshandiswa kunze kweganda uye furemu yemotokari, ngatirambei tichinzwisisa alloy structural simbi yemotokari yakavanzwa mukati memuviri wemotokari. Kunyanya zvinosanganisira: shaft
Shandisa simbi yakadzimwa uye yakadzikama uye isingadzimi uye yakadzikama
Simbi, giya simbi, marudzi ese esimbi emabara uye ese marudzi esimbi epamusoro-simba chiyero zvikamu.
1. Simbi dzakadzimwa uye dzakadzikama uye dzisina kudzimwa uye dzakadzikama simbi ye shafts
Mumotokari, maekisi akasiyana anoita basa rakakosha. Chero bedzi motokari inotanga kumhanya, ivo vachabereka
Kushushikana kwakanyanya. Iyo yekumberi inoiswa pasi pekukotama kuneta kusagadzikana, curved kubereka
Pasi pekushushikana kwakasanganiswa kwekukotama uye torsion, iyo yekutakura inoiswa pasi pekunetsekana kwekuneta, uye mabheya ekubatanidza tsvimbo.
Zvichiiswa kune asymmetrical tension uye compression, ivo vanofanirwa ... kuitira kuvabvumira kushanda zvine hutano uye zvakachengeteka, shafts.
Simbi yakadzima uye yakapfava kazhinji ine mamwe maalloying zvinhu kuti ive nechokwadi chekudzima
Permeability (rudzi rwekugona kuona kuti simba rechikamu chimwe nechimwe chechikamu chemuchinjiko chinosangana nezvinodiwa zvechikamu), uye kuvandudza kuoma kwemhedzisiro.
sex. Parizvino, kudzima uye kudziya simbi ye crankshaft
Kune 40Cr, 42CrMo, zvichingodaro, mota hafu shafts inowanzoshandiswa muS45C, SCM4, SCM6, SAE1045, nezvimwewo, uye mota dzekubatanidza tsvimbo idzo dzakawanda-chinangwa dzakadzimwa uye dzakadzikama simbi.
40Cr, S48C. Aihwa
Simbi dzakadzimwa uye dzakapfava dzakadai se12Mn2VBS uye 35MnVN zvakare dzakashandiswa zvakanyanya mukudhiraivha knuckles uye injini yekubatanidza tsvimbo.
2. Gear simbi
Magiya zvakare chinhu chakakosha chekufambisa magetsi pamotokari. Izvo zvinodikanwa zvekuita zvegiya simbi ndezvi: yakakwirira kupwanya kuramba uye pitting corrosion resistance
Kugona; yakanaka kukanganisa kuramba uye kukotama
Kugona; kuomarara kwakakodzera, kudzika kwemutsetse wakaomeswa uye kuomarara kwepakati; yakanaka maitiro ekuita uye kucheka kugadzirisa
Performance; uye deformation uye dimensional kugadzikana. Gear simbi ine
SCM420, SCM822 uye mamwe Cr-Mo akatevedzana, Cr-Ni-Mo akatevedzana uye Ni-Mo akatevedzana.
3. Simbi yemabara
Zvitubu zvinoshandiswa mumotokari muhuwandu hukuru uye mumhando dzakawanda. Iwo chikamu chakakosha chechimiro. Iyo inonyanya kushandiswa isimbi elastic yekumisa uye valve spring simbi.
, Mumarori akareruka kana anorema, kumiswa kwechirimo
Muyero weraki unowanzo 100-500kg. Izvo zvinodikanwa zvekuita zvechitubu simbi ndezvi: yakakwira elastic muganho uye kuzorora
Kupokana, kuoma kwakanaka uye kwakakodzera kuomarara, kuomarara kwepamusoro kutsemuka
Kupokana uye kunetsa kuneta hupenyu, yakanaka metallurgical process performance uye formability, -
Imwe abrasion resistance uye corrosion resistance. Parizvino, simbi yekumisa zvitubu inonyanya kusanganisira: Si-Mn akatevedzana, Mn-Cr
Dhipatimendi, Dhipatimendi reCR-V. Mn-Cr-B, nezvimwewo.
4. Simbi yezvikamu zvakasiyana-siyana zvepamusoro-soro
Mumakore achangopfuura, yakakwirira-simba chiyero zvikamu zvakawedzera zvishoma nezvishoma mumashandisirwo emotokari. Simbi ye riveting screws imwe yacho. Zvinoda
Kuita kwakanaka kwemaitiro, machinability, kuita kwesimba
Kuita kuneta uye kunonoka kutyoka kugona pasi pesimba rakakura.
