ASF - Audi Space Frame

ASF inonyanyo sanganisira yakavharwa zvikamu zvakasimudzwa zvakabatanidzwa kune mumwe nemumwe nenzira yemajekiseni akaumbwa magungano. Maererano neAudi, iyo recyclability kashanu iyo yesimbi.

Simba rose rinodiwa pakugadzirwa i152-163 GJ zvichienzaniswa ne127 GJ yengoro yesimbi yakafanana.

Extruded

Chaizvoizvo, ivo vanofananidzwa nebhokisi-yakaita bhokisi. Ma alloys anoshandiswa haana kuburitswa Al-Si alloys ane Si yemukati yakakura kupfuura 0,2% kuve nechokwadi chekuyerera uye kunaya kwemvura kuoma panguva yekuchembera kwekugadzira.

machira

Inoshandiswa pakutakura mapaneru, slabs, matenga uye firewall, inotora 45% yehuremu hwechimiro. Ukobvu hwavo hunosvika 1.7-1.8 nguva huru kupfuura yesimbi. Iyo yakashandiswa alloy 5182 muT4 state (yakanyanya kuremara) ine elastic muganho we140-395 MPa. Inogona kutsigirwa kunyangwe iine isingasviki 7% magnesium nekuda kwekuvapo kwemamwe maalgants.

Cast units

Ivo vanoshandiswa munzvimbo dzine kushushikana kukuru.

Zvinoitwa pachishandiswa maitiro anonzi VACURAL, ayo anosanganisira kubaya aluminium mvura muvacuum molds kuti uwane:

Hunhu hwepamusoro uye hwakafanana, hwakaderera porosity, kuvimbisa yakakwirira michina zvivakwa pamwe nekuomarara kunodiwa pakuramba kuneta;

Weldability yakanaka inodiwa pakujoinha nemaprofiles.

Nzira dzekubatanidza

Nzira dzakawanda dzinoshandiswa:

MIG welding: inoshandiswa kune matete mapepa uye yekubatanidza node kune mbiri;

Spot welding: yepepa simbi isingasvikike nembambo dzembambo;

Stapling: yekukosha kwechipiri kubva pachimiro chechimiro nekuda kwekuderedzwa static kuramba; inoshandiswa pakubatanidza mapepa ekusimbisa nzvimbo dzakatambanudzwa;

Riveting: inoshandiswa mukubereka zvinhu zvine nzvimbo yakawedzera; nehupamhi hwakafanana, ine kuramba inopfuura 30% kana ichienzaniswa newelding; iyo inewo mukana wekuda simba shoma uye haishanduki maitiro ezvinyorwa.

Structural adhesives: anoshandiswa girazi rakagadzika, musuwo uye majoini ebhoneti (pamwe chete ne screwing), mu shock absorber zvinotsigira (pamwe chete ne riveting uye welding).

Gungano

Mushure mekuumbwa, kusangana kunoitwa nerobhoti welding yezvikamu.

Kupedzisa kunoitwa nekukuya uye phosphating ne 3 cations (Zn, Ni, Mn), iyo inokurudzira kusungirirwa kwe cataphoresis layer nekunyura.

Kupenda kunoitwa nenzira yakafanana neyemitumbi yesimbi. Pari zvino, kuchembera kwekutanga kwekutanga kunoitika, izvo zvinozopedzwa nekuwedzera kupisa kurapwa pa210 ° C kwemaminitsi makumi matatu.
