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. Qiniseka ukuthi umshayeli uyakwazi ukulawula lapho ebheka khona 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. .
