Daim ntawv thov scenarios rau automotive structural fasteners nyob rau hauv lub 1000-10,000 daim ntau yog mas concentrated nyob rau hauv lub tsheb sib dhos theem, npog cov tub ntxhais modules xws li lub cev, chassis, powertrain, thiab tshiab lub zog tsheb peb-hluav taws xob system.
Raws li kev lag luam cov ntaub ntawv, qhov nruab nrab ntawm cov fasteners siv ib lub tsheb yog 3000-5000 daim, thaum ib co tshiab lub zog tsheb qauv, vim lub roj teeb pob qauv thiab lub teeb yuag, siv tau ntau tshaj 10,000 daim. Daim ntawv thov tshwj xeeb scenarios yog raws li hauv qab no:
1. Lub cev-hauv-Dawb (BIW) thiab Lub Cev Lub Cev
Tus naj npawb ntawm cov ntawv thov: kwv yees li 1000-2000 daim
Hom Lub Npe: Tus kheej-tapping screws, qhov chaw-welded studs, tus kheej- tho rivets, ntws laum screws
Muaj nuj nqi: Txuas lub qhov rooj, hoods, longitudinal beams, crossbeams, thiab lwm yam, kom lub cev rigidity thiab kev sib tsoo kev nyab xeeb
Technological Trend: Steel-aluminium hybrid cov ntaub ntawv yog tsav txoj kev loj hlob ntawm riveting thiab adhesive bonding txheej txheem.
2. Chassis thiab Suspension System
Tus naj npawb ntawm cov ntawv thov: kwv yees li 500-800 daim
Hom Lub Npe: Qib 12.9 siab- lub zog bolts, tag nrho - hlau locknuts, ua ntej- siv cov nplaum nplaum
Muaj nuj nqi: Kho cov caj npab, kev poob siab absorbers, thiab lub kauj khawm, tiv nrog ntev - lub sij hawm vibration thiab cuam tshuam loads
Tshwj xeeb yuav tsum tau: Anti-loosing, qaug zog-resistant, corrosion{2}}resistant; feem ntau siv ua ke nrog xov -locking nplaum.
3. Powertrain System (Tsev tsheb roj av)
Tus naj npawb ntawm cov ntawv thov: kwv yees li 600-1000 daim
Hom Lub Npe: Siab-lub zog sab hauv hex bolts, yas-zone nruj bolts, lub xub pwg bolts
Muaj nuj nqi: Txuas lub tog raj kheej taub hau, crankshaft, thiab camshaft, kom ntseeg tau tias lub cav sealing thiab ruaj khov ua haujlwm.
Cov txheej txheem yuav tsum tau ua: yuav tsum tau nruj siv txoj kev "cross-kauj ruam ceev"; torque yuam kev Tsawg dua los yog sib npaug li 5%.
4. Tshiab Zog Tsheb Peb-Electric System
Tus naj npawb ntawm cov ntawv thov: 800-1500 daim tshiab (tshwj xeeb yog cov roj teeb pob)
Hom Lub Npe:
Roj teeb pob Cov Bolts Dedicated: Siab- zog, tiv thaiv-galvanic corrosion txheej, insulating washers
Hluav taws xob txuas Bolts: Silver-plated, tsis tshua muaj kev sib cuag, tiv thaiv fretting corrosion
Lub cev muaj zog / Hluav taws xob tswj Fasteners: Muaj cov yam ntxwv ntawm electromagnetic shielding, tiv taus siab - zaus vibration
Txoj Kev: NIO, Li Auto, thiab lwm yam automakers tab tom nrhiav lub teeb yuag welded fasteners hauv ntau kom ua tiav qhov sib npaug ntawm lub zog siab thiab txo qhov hnyav.
