Lub leveling valve (tseem hu ua qhov siab tswj valve) yog qhov tseem ceeb hauv cov tshuab cua ncua kev kawm, feem ntau yog siv hauv cov tsheb lag luam, tsheb thauj khoom, tsheb npav, thiab cov tsheb thauj khoom. Nws lub luag haujlwm tseem ceeb yog kom tswj tau lub tsheb sib npaug qhov siab tsis hais txog kev hloov pauv lossis txoj kev.
Nws ua haujlwm li cas (Simplified):
Monitors Qhov siab - Siv cov khoom sib txuas los yog cov ntsuas ntsuas kom pom qhov deb ntawm lub chassis thiab axles.
Kho Huab Cua Siab - Yog tias lub tsheb qis dhau lawm, nws qhib lub tshuab cua kom ua rau lub tshuab nqus cua (lub hnab). Yog tias siab dhau, nws tso cua kom txo lub tsheb.
Locks ntawm Teeb Qhov siab - Thaum qhov siab yog mus txog, nws nres airflow kom ruaj khov.
Lub luag haujlwm tseem ceeb:
✔ Load Compensation - Khaws lub tsheb theem txawm tias nqa hnyav lossis tsis sib xws.
✔ Txhim khu kev ruaj ntseg - Ua kom lub log kom zoo thiab tuav.
✔ Kev nplij siab - Txo lub cev yob thiab kev co rau kev caij tsheb zoo dua.
✔ Kev Nyab Xeeb - Tiv thaiv kev sagging lossis siab dhau qhov kev hloov pauv uas tuaj yeem cuam tshuam rau braking / kauj.
Kev siv ntau:
Tsheb & Trailers – Tiv thaiv rear - kawg sag thaum loaded.
Tsheb npav - Khaws qhov siab nkag / tawm kom zoo ib yam.
Cov Khoom Siv Hnyav - Khaws cov cranes lossis cov chaw ua haujlwm ruaj khov.
Cov tsos mob ua tsis tiav:
⚠️ Qhov siab tsis sib xws
⚠️ Air suspension tsis kho
⚠️ Ntau dhau cua compressor cycling
