Isimiso kanye nokusetshenziswa kwenzwa ye-automobile abs
Isimiso sokusebenza se-automobile abs yile:
Ekubhulekeni okuphuthumayo, kuncike ku-sensor yesivinini samasondo ebucayi kakhulu efakwe esondweni ngalinye, kutholakala i-wheel lock, bese ikhompyutha ilawula ngokushesha i-pressure regulator ukuze inciphise ingcindezi ye-brake pump yesondo ukuze ivimbele i-wheel lock. Uhlelo lwe-abs luqukethe i-abs pump, i-wheel speed sensor kanye ne-brake switch.
Indima yesistimu ye-abs yile:
1, gwema ukulahlekelwa ukulawula imoto, wandise ibanga lokubhuleka, uthuthukise ukuphepha kwemoto;
2, ukuthuthukisa ukusebenza kahle kokubhuleka kwemoto;
3, ukuvimbela isondo enqubweni yokubhuleka;
4. Qinisekisa ukuthi umshayeli uyakwazi ukulawula indlela lapho ebhuleka futhi avimbele i-axle yangemuva ukuthi ingasheleli.
Indima ye-ABS, njengoba igama lisho, indima eyinhloko yesistimu yokubhuleka evimbela ukukhiya iwukuvimbela isondo ukuthi lingakhiywa ngenxa yamandla amakhulu okubhuleka uma kwenzeka imoto ibhuleka ngokuphuthumayo, okubangela ukuba imoto ilahlekelwe ukulawula idivayisi. Isibonelo, uma sithola isithiyo phambi kwethu, imoto efakwe uhlelo lwe-ABS ingaqondisa kalula ukuze igweme ukubhuleka ngokuphuthumayo ngesikhathi esifanayo.
Uma imoto ingenalo uhlelo lwe-ABS ekubhulekeni okuphuthumayo, ngoba amandla okubhuleka amasondo amane afana, ukungqubuzana kwethayi phansi kuyafana, ngalesi sikhathi imoto izoba nzima kakhulu ukuyijika, futhi kulula ukubangela ingozi yokuthi imoto ilahlekelwe ukulawula. Kwanele ukubona ukuthi uhlelo lwe-ABS lubaluleke kangakanani ekuphepheni kwethu kokushayela. Akudingeki sikhathazeke ngalokhu, manje indinganiso kazwelonke iphoqelele izinkampani zezimoto enqubweni yokukhiqiza izimoto ukuthi zibe uhlelo olujwayelekile lwe-ABS oluvimbela ukukhiya.
Ngakho-ke uhlelo lokubhuleka oluvimbela ukukhiya lwe-ABS lusebenza kanjani? Ngaphambi kokuqonda isimiso salo sokusebenza, kumele siqale siqonde izingxenye zohlelo lokukhiya lwe-ABS, i-ABS yakhiwe kakhulu yinzwa yesivinini samasondo, iyunithi yokulawula kagesi, isilawuli se-hydraulic samabhuleki, i-brake master cylinder nezinye izingxenye. Uma imoto idinga ukubhuleka, inzwa yesivinini samasondo esondweni izobona isignali yesivinini samasondo amasondo amane ngalesi sikhathi, bese iyithumela ku-VCU (isilawuli sezimoto), iyunithi yokulawula ye-VCU izohlaziya lezi zimpawu ukuze inqume isimo semoto ngalesi sikhathi, bese i-VCU ithumela umyalo wokulawula ingcindezi yamabhuleki kumlawuli wengcindezi ye-ABS (ipompo ye-ABS).
Uma isilawuli sokucindezela se-ABS sithola imiyalelo yokulawula ukucindezela kwebhuleki, silawula ngokuqondile noma ngokungaqondile ukucindezela kwebhuleki kwesiteshi ngasinye ngokulawula i-valve yangaphakathi ye-solenoid yesilawuli sokucindezela se-ABS, ukuze silungise i-torque yokubhuleka yamasondo amane, ukuze siyivumelanise nokunamathela komhlaba, futhi sivimbele isondo ekukhiyweni ngenxa yamandla amakhulu okubhuleka.
Abashayeli abaningi abadala ababona lapha bangase bacabange ukuthi sivame ukushayela i-"spot brake" kungaba nomphumela wokulwa nokukhiya. Kudingeka kugcizelelwe lapha ukuthi lo mqondo uphelelwe yisikhathi, futhi kungashiwo nokuthi indlela ye-"spot brake" yokubhuleka ngezikhathi ezithile ithinte ukuphepha kokushayela.
Kungani usho kanjalo? Lokhu kuzoqala kusukela ekuqaleni "kwebhuleki eliyi-spot", okubizwa ngokuthi "ibhuleki eliyi-spot", alinawo uhlelo lwe-ABS oluvimbela ukukhiya emotweni ngokunyathela ngokwenziwa ukusebenza kwebhuleki elingaqhubeki kwephedali, ukuze amandla okubhika amasondo ngezinye izikhathi angabi khona, ukuze kuvinjelwe umphumela wokukhiya amasondo. Kufanele kuqashelwe lapha ukuthi manje imoto inawo wonke uhlelo olujwayelekile lwe-ABS oluvimbela ukukhiya, izinhlobo ezahlukene zesistimu yokulwa nokukhiya zizoba nomehluko othile, kodwa ngokuyisisekelo zingenza isignali yokuthola izikhathi eziyi-10 ~ 30 / ngomzuzwana, inani lokubhika izikhathi ezingama-70 ~ 150 / ngomzuzwana imvamisa yokusebenza, lokhu kuqonda kanye nemvamisa yokusebenza akunakwenzeka ukufinyelela.
Uhlelo lokubhuleka oluvimbela ukukhiya lwe-ABS ludinga ukuba lubhuleke njalo ukuze ludlale kahle umsebenzi walo. Uma sibhuleka ngokungahleliwe "ngokwe-spot-brake", uhlelo lokubhuleka oluvimbela ukukhiya lwe-ABS luthola isignali yokuthola ngezikhathi ezithile, kanti i-ABS ngeke ikwazi ukusebenza kahle, okuzoholela ekunciphiseni ukusebenza kahle kokubhuleka ngisho nebanga elide kakhulu lokubhuleka.
