Isimiso kanye nokusetshenziswa kwenzwa ye-abs yemoto
Umgomo wokusebenza we-automobile abs uthi:
Ku-braking yezimo eziphuthumayo, kuncike kwinzwa yejubane ezwela kakhulu efakwe esondweni ngalinye, kutholwa ilokhi yesondo, futhi ikhompuyutha ilawula ngokushesha isilawuli sokucindezela ukuze ikhulule ukucindezela kwephampu yebhuleki yesondo ukuvimbela ilokhi yesondo. Uhlelo lwe-abs luqukethe iphampu ye-abs, inzwa yesivinini samasondo kanye ne-brake switch.
Indima yesistimu ye-abs yile:
1, gwema ukulahleka kokulawula kwemoto, ukwandise ibanga lokubhuleka, uthuthukise ukuphepha kwemoto;
2, ukuthuthukisa ukusebenza kwamabhuleki wemoto;
3, ukuvimbela isondo in the inqubo braking;
4. Qinisekisa ukuthi umshayeli uyakwazi ukulawula indlela lapho ebhuleka futhi avimbele i-asi yangemuva ukuthi ingasheleli.
Iqhaza le-ABS, njengoba negama lisho, indima enkulu ye-anti-lock braking system ukuvimbela isondo ukuthi lingakhiyeki ngenxa ye-braking force uma kwenzeka ibhuleki eliphuthumayo lemoto, okwenza imoto ingasakwazi ukulawula. idivayisi. Isibonelo, uma sithola isithiyo phambi kwethu, imoto efakwe uhlelo lwe-ABS ingakwazi ukuqondisa kalula ukugwema ukubhuleka okuphuthumayo ngesikhathi esifanayo.
Lapho imoto ingahlonyiwe ngesistimu ye-ABS ekubambeni okuphuthumayo, ngoba amandla okubhuleka amasondo amane ayafana, ukungqubuzana kwesondo phansi kuyafana, ngalesi sikhathi imoto izoba nzima kakhulu ukuyijika. , futhi kulula ukubangela ingozi yokulahlekelwa yimoto. Kwanele ukubona ukuthi uhlelo lwe-ABS lubaluleke kangakanani ekuphepheni kwethu kokushayela. Akufanele sikhathazeke ngalokhu, manje izinga likazwelonke liye laphoqelela izinkampani zezimoto ohlelweni lokukhiqiza izimoto kufanele kube uhlelo olujwayelekile lwe-ABS anti-lock.
Ngakho-ke i-ABS anti-lock braking system isebenza kanjani? Ngaphambi kokuqonda isimiso sayo sokusebenza, kufanele siqale siqonde izingxenye ze-ABS anti-lock system, i-ABS ikakhulukazi yakhiwa inzwa yesivinini samasondo, iyunithi yokulawula i-electronic, i-brake hydraulic regulator, i-brake master cylinder nezinye izingxenye. Uma imoto idinga ukubhuleka, inzwa yesivinini sesondo esondweni izobona isignali yesivinini samasondo amane ngalesi sikhathi, bese iyithumela ku-VCU (isilawuli semoto), iyunithi yokulawula ye-VCU izohlaziya lawa masignali ukuze inqume. isimo semoto ngalesi sikhathi, bese i-VCU ithumela umyalo wokulawula i-brake pressure ku-ABS pressure regulator (Iphampu ye-ABS).
Lapho i-ABS pressure regulator ithola umyalelo wokulawula i-brake pressure, ilawula ngokuqondile noma ngokungaqondile ingcindezi yebhuleki yesiteshi ngasinye ngokulawula i-valve yangaphakathi ye-solenoid ye-ABS pressure regulator, ukuze ilungise i-torque yokubhuleka yamasondo amane, ukuze ivumelanise nokunamathela komhlabathi, futhi uvimbele isondo ukuthi lingakhiywa ngenxa yamandla amakhulu okubhuleka.
Abashayeli abaningi abadala ababona lapha bangase bacabange ukuthi ngokuvamile sishayela "i-spot brake" ingadlala umphumela wokulwa nokukhiya. Kumele kugcizelelwe lapha ukuthi lo mqondo usuphelelwe yisikhathi, kungathiwa indlela ye-"spot brake" i-intermittent braking iphazamise ukuphepha kokushayela.
Kungani usho kanjalo? Lokhu kufanele kuqale kusukela lapho kuvela khona "i-spot brake", ebizwa ngokuthi "i-spot brake", ayifakelwe i-ABS anti-lock system emotweni ngokunyathela ngokungemthetho ukusebenza okungaqhubeki kwe-brake ye-pedal, ukuze I-wheel braking force ngezinye izikhathi ayikho, ukuze kuvinjwe umphumela wokukhiya isondo. Kufanele kuqashelwe lapha ukuthi manje imoto has zonke standard ABS anti-lock uhlelo, izinhlobo ezahlukene anti-lock uhlelo kuyoba umehluko othile, kodwa ngokuyisisekelo angenza isignali ukuthola 10 ~ 30 izikhathi / wesibili, inani braking 70. ~ Izikhathi eziyi-150/isekhondi lokusebenzisa imvamisa, lo mbono kanye nemvamisa yokubulawa akunakwenzeka ukufinyelela.
I-anti-lock braking system ye-ABS idinga ukuba ku-braking eqhubekayo ukuze idlale kahle umsebenzi wayo. Uma senza “i-spot-brake” ngokuzenzela, i-anti-lock braking system ye-ABS ithola isignali yokubona ngezikhathi ezithile, futhi i-ABS ngeke ikwazi ukusebenza kahle, okuzoholela ekwehleni kokusebenza kwamabhuleki kanye nebanga elide kakhulu lokubhuleka. .
