Muaj ob feem ntau siv cov txheej txheem hauv cov ntawv hlau ua cov chassis casings, uas yog steel profiles thiab aluminium profiles. Txawm hais tias lub zos steel kem thav duab tshuab yog kaw thiab muaj peev xwm thauj khoom loj, nws nyuaj rau kev ntxuav cov phab ntsa sab hauv thiab daws qhov teeb meem ntawm corrosion ntawm sab hauv phab ntsa. Lub chassis yog lub plhaub sab nraud ntawm cov khoom siv hluav taws xob me me thiab nruab nrab, nrog lub thawv zoo li tus qauv. Nws tuaj yeem muab faib ua cov qauv hlau chassis, aluminium profile qauv chassis, cam khwb cia qauv chassis, thiab cov khoom tsis yog xim hlau chassis, thiab lwm yam. Tam sim no, aluminium profile structural chassis tau siv dav hauv cov khoom siv hluav taws xob.
Hauv kev tsim qauv ntawm lub chassis plhaub ntawv hlau ua, hais txog nws cov khoom siv tes ua haujlwm, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
1. Kev yooj yim ntawm kev sib dhos thiab kev xaim yuav tsum tau xav txog.
2. Qhov chaw rau arc vuam thiab roj vuam yuav tsum tsis txhob coated rau saum npoo ua ntej vuam.
3. Thaum vuam qhov chaw, nws yog ib qho tsim nyog los xyuas kom meej qhov me me deformation tom qab vuam nyob rau hauv cov nqe lus ntawm cov khoom thickness thiab weld ntev.
4. Ntawm qhov chaw ua tau raws li qhov yuav tsum tau ua rau chassis plhaub ntawv hlau ua, sim ua kom cov qauv yooj yim thiab txo cov khoom siv tsawg.
5. Cov profile (cov khoom siv) yuav tsum sib zog ua kom yooj yim sib dhos thiab txo cov kauj ruam ua haujlwm thaum ua tau raws li qhov yuav tsum tau muaj zog, nruj, thiab zoo nkauj.
6. Cov qauv tsim thiab cov qauv tsim thiab cov qauv loj yuav tsum tau siv ntau npaum li qhov ua tau kom yooj yim rau kev xaiv cov cuab yeej siv thoob ntiaj teb thaum lub sij hawm chassis plhaub ntawv hlau ua, txo cov naj npawb ntawm cov khoom tsis zoo, thiab ua rau lawv cov qauv yooj yim.
