Qhov poob- sab semi-trailer nta ib qho qauv tsim los ua ke. Lub chassis ua haujlwm tseem ceeb hauv kev thauj khoom -cov kabmob hauv paus; nws feem ntau yog tsim los ntawm vuam siab - lub zog longitudinal thiab transverse beams los tsim ib tug ruaj khov, kab sib chaws -zoo li load-cov kabmob uas txhawb nqa cov khoom thauj thiab faib cov khoom sib npaug rau cov axles. Txhawm rau txhim kho tag nrho rigidity, qhov tseem ceeb load-cov kabmob feem ntau suav nrog kev txhawb nqa hauv zos.
Kev poob -sab sab yog ib qho kev txhais cov yam ntxwv, feem ntau suav nrog lub vaj huam sib luag pem hauv ntej, sab vaj huam sib luag, thiab lub rooj vag tom qab, muaj nyob rau hauv kev ruaj khov lossis qhib tau. Sab vaj huam sib luag feem ntau txuas nrog lub chassis ntawm hinges lossis xauv pins kom yooj yim thauj khoom thiab tshem tawm, thaum lub rooj vag tom qab feem ntau siv cais- qhib lossis poob - qauv tsim kom haum rau ntau txoj kev tuav. Qee cov qauv kuj tseem muaj cov kev cai rau uprights, tso cai rau kev nce sab - vaj huam sib luag qhov siab los yog kev teeb tsa ntawm ceg txheem ntseeg - sab qauv los txhim kho cov khoom thauj thiab kev tiv thaiv.
Lub trailer tseem suav nrog cov khoom tseem ceeb xws li kev ncua, kev sib tsoo, thiab cov tshuab hluav taws xob. Cov tshuab raug ncua feem ntau siv cov nplooj hlav los yog cov cua ncua kev kawm kom nqus tau txoj kev poob siab thiab tswj kev tsav tsheb. Braking systems feem ntau siv pneumatic brakes kom ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm hnyav- thauj khoom thauj, thaum lub tshuab hluav taws xob tswj cov teeb pom kev zoo thiab cov teeb liab kis tau los ua kom muaj kev nyab xeeb hauv kev tsav tsheb nyuaj. Lub tswv yim tsim tag nrho qhia txog qhov sib npaug ntawm cov qauv kev ntseeg tau thiab kev ua haujlwm yooj yim.
