Rau hnyav -duty semi-trailers, ABS (Anti-lock Braking System) thiab EBS (Electronic Braking System) yog cov cuab yeej tseem ceeb ntawm kev nyab xeeb. Ua los ntawm cov qauv pneumatic braking cov qauv, lawv ua tau zoo txhim kho kev ruaj ntseg braking thiab tag nrho braking kev ua tau zoo nyob rau hauv txhua hnub thiab thaum muaj xwm ceev tsav tsheb scenarios.
ABS yog qhov yooj yim tiv thaiv -lock braking tiv thaiv rau kev ua haujlwm trailer. Lub kaw lus siv lub log ceev sensors txuas ntxiv taug qab cov xwm txheej tig ntawm txhua lub log. Thaum cov neeg tsav tsheb nres nrawm los yog taug kev ntawm txoj kev ntub dej, dej khov thiab nplua, lub log tsheb yooj yim kom kaw tag nrho thiab plam kev sib txhuam nrog txoj kev, uas ua rau sab plhu, trailer sway los yog jackknife txaus ntshai. Lub onboard tswj tsev ceev ceev txheeb xyuas lub log xauv cov paib thiab ua rau cov solenoid li qub kom dynamically kho cua nres siab los ntawm kev rov ua kom lub zog thiab tso tawm mus. Qhov kev tsim no tso cai rau cov log kom me ntsis tig lub xeev thaum lub sijhawm braking, khaws cia tswj lub kauj thiab tsis txhob muaj kev phom sij rau kev nyab xeeb.
EBS yog ib qho khoom siv hluav taws xob zoo tshaj plaws uas suav nrog tag nrho ABS kev tiv thaiv -lock functions thiab optimizes cov tsoos braking logic. Tsis zoo li pneumatic braking nkaus xwb nrog cov teeb liab pom tseeb qeeb, EBS hloov tus tsav tsheb pedal nres ua haujlwm hauv hluav taws xob thiab xa lawv mus rau electro-pneumatic regulators los ntawm CAN tsheb npav hauv lub sijhawm. Nws muaj peev xwm ntawm nws tus kheej thiab sib npaug faib cov quab yuam ntawm txhua lub qag thiab lub log, ua raws sijhawm raws li qhov tseeb trailer loads thiab txoj kev. Qhov no ua rau txo qis braking teb lag, paub txog kev sib koom ua ke ntawm lub tsheb laij teb thiab trailer, thiab txo qhov kev sib tsoo zoo. Tsis tas li ntawd, cov qauv pneumatic thaub qab uas sib koom ua ke tau lees tias cov khoom siv hluav taws xob zoo li qub yog tias cov khoom siv hluav taws xob ua tsis tiav, xa ntau qhov ruaj khov thiab txhim khu kev ruaj ntseg tag nrho kev tiv thaiv rau hnyav semi-trailers.
