ASR solenoid valve yog ob-txoj haujlwm peb- txoj kev solenoid valve, uas yog qhib thaum lub log tsav, lub solenoid valve core txav mus qhib cua nkag, cov cua compressed ob { {2}} txoj hauj lwm thim rov qab valve, thiab lub relay valve tig mus rau ob - txoj hauj lwm rov qab valve. Cov kav dej nres ntawm lub valve raug kaw, thiab cov cua compressed ntws los ntawm peb -txoj kev mus rau sab laug thiab sab xis ABS solenoid li qub, thiab tom qab ntawd mus rau lub tshuab nres cua ntawm sab laug thiab sab xis lub zog cia nres.
Lub tsheb loj neeg nrog caij pom tias thaum lub clutch pedal tau slammed pib, ASR qhov taw qhia lub teeb flashed sai sai thiab tawm mus, thiab ob lub log tsav tsheb tau tshwm sim los xauv thiab kaw. Ob lub tsheb nres yog nyob rau hauv lub xeev braking. Unscrew lub rear zog cia nres nres cua chamber nres yeeb nkab, thiab ces pib dua. Thaum lub log kaw, lub suab ntawm cov pa tawm tuaj yeem hnov: tom qab zawm lub zog nres nres nres cua chamber cua yeeb nkab, loosen cov pa tawm. Qhib ASR solenoid valve rau lub qhov hluav taws xob cov yeeb nkab ntawm ob - txoj hauj lwm rov qab valve. Thaum lub log log tshwm sim thaum pib, koj hnov lub suab ntawm huab cua to, thiab nres kom txog thaum lub log log raug tshem tawm. Nws tau ua pov thawj tias thaum ASR qhov system tsis ua haujlwm, uas yog, tom qab lub kauj ntawm ASR solenoid valve raug kaw, tseem muaj lub siab nyob hauv cov kav dej, thiab ASR solenoid valve core yog daig hauv qhov qhib.
Qhov laj thawj ntawm qhov ua tsis tiav no tau txheeb xyuas. Lub tsheb npav loj ASR valve tau teeb tsa ntsug ntawm tus ncej ntawm lub log tsav, thiab qhov chaw nres nkoj tso tawm yog nce. Tom qab siv sijhawm ntev -, cov roj hmab plua plav hau ntawm ASR valve chaw nres nkoj yog laus thiab puas, thiab cov av loj tuaj. Tom qab qhov chaw nres nkoj tso tawm, qhov tso pa tawm ntawm ASR solenoid valve nce ntxiv thiab cov roj hmab plua plav tau ntxuav tawm. Tom qab ASR solenoid poob nws qhov kev tiv thaiv, vim yog qhov chaw ua haujlwm hnyav, ntau cov av nkos thiab av nkag mus rau ASR solenoid valve los thaiv lub valve kab noj hniav thiab ua rau lub solenoid valve. Lub hauv paus yog corroded, thiab lub solenoid valve core yog daig.
Therefore, it is suspected that the installation method of the ASR solenoid valve is improper. Consult the WABCO manual and find that the ABS solenoid valve and the ASR differential valve exhaust port are required to be installed downwards. And it is required that the inclination angle is less than ±30 degree , and the same batch of ZF axle vehicles is checked. The exhaust ports of the ASR differential valve are all installed upwards, and the dust caps of some vehicles have fallen off. It is also found that the two-position reversing valve of this batch of vehicles is Parallel installation, not vertical installation according to the two-position reversing valve recommended by WABCO company, installation method with the intake port of the brake relay valve facing upwards. requirements to re-install. Effectively avoid the occurrence of similar failures.
