Umgaqo kunye nokusetyenziswa kwe-sensor ye-abs yemoto
Umgaqo wokusebenza we-automobile abs ngulo:
Kwi-emergency braking, exhomekeke kwi-sensor ye-wheel speed sensor ebukhali kakhulu efakwe kwivili ngalinye, i-wheel lock ifunyenwe, kwaye ikhompyutha ilawula ngoko nangoko i-pressure regulator ukuze inciphise uxinzelelo lwe-brake pump yevili ukuze ithintele i-wheel lock. Inkqubo ye-abs ine-ab pump, i-wheel speed sensor kunye ne-brake switch.
Indima yenkqubo ye-abs yile:
1, kuphephe ukulahlekelwa lulawulo lwesithuthi, yonyusa umgama wokubhuleka, iphucule ukhuseleko lwesithuthi;
2, ukuphucula ukusebenza kokubhuleka kwesithuthi;
3, ukuthintela ivili kwinkqubo yokubhuleka;
4. Qinisekisa ukuba umqhubi uyakwazi ukulawula icala xa ebhuleka aze athintele i-axle engasemva ukuba ingatyibiliki.
Indima ye-ABS, njengoko igama lisitsho, indima ephambili yenkqubo yokuqhobosha ethintela ukutshixwa kukuthintela ivili ukuba lingatshixwa ngenxa yamandla okuqhobosha amaninzi xa imoto iqhobosha ngokukhawuleza, nto leyo ebangela ukuba imoto ilahlekelwe lulawulo lwesixhobo. Umzekelo, xa sifumana umqobo phambi kwethu, imoto exhotyiswe ngenkqubo ye-ABS inokujika ngokulula ukuze iphephe ukuqhobosha ngokukhawuleza ngaxeshanye.
Xa imoto ingenazo izixhobo ze-ABS kwinkqubo yokuqhobosheka ngexesha likaxakeka, kuba amandla okuqhobosheka kwamavili amane afana, ukungqubana kwetayara emhlabeni kuyafana, ngeli xesha imoto iya kuba nzima kakhulu ukuyijika, kwaye kulula ukubangela ingozi yokuba imoto ilahlekelwe lulawulo. Kwanele ukubona ukuba inkqubo ye-ABS ibaluleke kangakanani kukhuseleko lwethu lokuqhuba. Akufuneki sikhathazeke ngale nto, ngoku umgangatho wesizwe unyanzelise iinkampani zeemoto kwinkqubo yokuvelisa izithuthi ukuba zibe yinkqubo eqhelekileyo ye-ABS yokulwa nokutshixa.
Ngoko ke isebenza njani inkqubo yokuqhoboshela i-ABS echasene nokutshixa? Ngaphambi kokuba siqonde umgaqo wayo wokusebenza, kufuneka siqale siqonde izinto eziyinxalenye yenkqubo yokuqhoboshela i-ABS, i-ABS yenziwe ikakhulu yi-sensor yesantya samavili, iyunithi yolawulo lwe-elektroniki, i-brake hydraulic regulator, i-brake master cylinder kunye nezinye iindawo. Xa imoto kufuneka iqhoboshe, i-sensor yesantya samavili kwivili iya kubona isignali yesantya samavili amane ngeli xesha, ize emva koko iyithumele kwi-VCU (umlawuli wesithuthi), iyunithi yolawulo lwe-VCU iya kuhlalutya ezi mpawu ukuze ibone imeko yesithuthi ngeli xesha, ize emva koko i-VCU ithumele umyalelo wolawulo loxinzelelo lwe-brake kwi-ABS pressure regulator (i-ABS pump).
Xa i-ABS pressure regulator ifumana umyalelo wolawulo loxinzelelo lweebhuleki, ilawula ngokuthe ngqo okanye ngokungathanga ngqo uxinzelelo lweebhuleki zetshaneli nganye ngokulawula ivalvu yangaphakathi ye-solenoid ye-ABS pressure regulator, ukuze ilungise i-braking torque yamavili amane, ukuze ilungelelanise ukunamathela komhlaba, kwaye ithintele ivili ekutshixweni ngenxa yamandla okuqhobosheka agqithisileyo.
Abaqhubi abaninzi abadala ababona apha banokucinga ukuba sihlala siqhuba i-"spot brake" inokudlala indima yokulwa nokutshixa. Kufuneka kugxininiswe apha ukuba le ngcamango iphelelwe lixesha, kwaye kunokuthiwa nendlela ye-"spot brake" yokubhrakha okukhawulezileyo ichaphazele ukhuseleko lokuqhuba.
Kutheni usitsho njalo? Oku kukuqala kwimvelaphi ye-"spot brake", ebizwa ngokuba yi-"spot brake", ayinayo inkqubo ye-ABS anti-lock kwisithuthi ngokunyathela ngokungekho mthethweni ukusebenza kwe-pedal ye-brake, ukuze amandla okubhuleka kwevili ngamanye amaxesha angangeni, ukuze kuthintelwe isiphumo sokutshixa kwevili. Kufuneka kuqatshelwe apha ukuba ngoku imoto inayo yonke inkqubo ye-ABS anti-lock eqhelekileyo, iintlobo ezahlukeneyo zenkqubo ye-anti-lock ziya kuba nomahluko, kodwa ngokusisiseko zingenza isignali yokubona amaxesha ali-10 ~ 30 / ngomzuzwana, inani le-brake amaxesha angama-70 ~ 150 / ngomzuzwana ukusebenza rhoqo, olu vavanyo kunye nokuphindaphinda kokusebenza akunakwenzeka ukufikelela.
Inkqubo yokuqhobosha ethintela ukutshixa ye-ABS kufuneka iqhubeke nokuqhobosha ukuze isebenze kakuhle. Xa siqhobosha ngokungabonakaliyo "ngokuqhawuka kwebhuleki", inkqubo yokuqhobosha ethintela ukutshixa ye-ABS ifumana isignali yokubhaqwa ngamanye amaxesha, kwaye i-ABS ayizukwazi ukusebenza kakuhle, nto leyo eya kukhokelela ekunciphiseni ukusebenza kakuhle kokuqhobosha kunye nomgama omde kakhulu wokuqhobosha.
