Umgaqo kunye nokusetyenziswa kwe-abs sensor yemoto
Umgaqo osebenzayo we-automobile abs ngulo:
Kwimeko yonxunguphalo olungxamisekileyo, kuxhomekeke kwinzwa yesantya esinovakalelo oluphezulu efakwe kwivili ngalinye, isitshixo sevili sifunyenwe, kwaye ikhompyuter ilawula ngokukhawuleza isilawuli soxinzelelo ukukhulula uxinzelelo lwempompo yebhuleki yevili ukuthintela ukutshixa ivili. Inkqubo ye-abs iquka impompo ye-abs, isantya sesondo senzwa kunye ne-brake switch.
Indima yenkqubo ye-abs yile:
I-1, ukuphepha ukulahleka kolawulo lwesithuthi, ukwandisa umgama wokunyathela, ukuphucula ukhuseleko lwesithuthi;
2, ukuphucula ukusebenza kwe-braking yesithuthi;
3, ukuthintela ivili kwinkqubo yokuqhobosha;
4. Qinisekisa ukuba umqhubi uyakwazi ukulawula indlela eya ngakulo xa ebhuleka kwaye athintele i-asi engasemva ekutyibilikeni.
Indima ye-ABS, njengoko igama libonisa, indima ephambili ye-anti-lock braking system kukuthintela ukutshixwa kwevili ngenxa yokunyanzeliswa kwamandla okunyathela kwimeko yonxunguphalo lwesithuthi, okubangela ukuba isithuthi siphulukane nolawulo. isixhobo. Ngokomzekelo, xa sifumana umqobo phambi kwethu, isithuthi esixhotyiswe nge-ABS singakwazi ukuhamba ngokulula ukunqanda ukunyathela ngokukhawuleza ngexesha elinye.
Xa isithuthi singaxhotyiswanga ngenkqubo ye-ABS kwi-braking yongxamiseko, ngenxa yokuba i-braking force yamavili amane iyafana, i-friction yetayara emhlabeni iyafana, ngeli xesha isithuthi siya kuba nzima kakhulu ukujika. , kwaye kulula ukubangela ingozi yesithuthi esiphulukene nolawulo. Kwanele ukubona indlela ebaluleke ngayo inkqubo ye-ABS kukhuseleko lwethu lokuqhuba. Asinakukhathazeka malunga noku, ngoku umgangatho welizwe unyanzelise iinkampani zemoto kwinkqubo yokuvelisa isithuthi kufuneka ibe yinkqubo ye-ABS yokuvala i-lock.
Ngoko ke, isebenza njani inkqubo yokuqhobosha isiqhoboshi ye-ABS? Ngaphambi kokuba siqonde umgaqo wayo wokusebenza, kufuneka siqale siqonde amacandelo enkqubo yokutshixa ye-ABS, i-ABS iqulunqwe ikakhulu ngesantya soluvo, iyunithi yokulawula i-elektroniki, isilawuli se-hydraulic brake, isilinda master brake kunye nezinye iindawo. Xa isithuthi sidinga ukuqhawula, i-sensor yesantya sevili kwivili iya kubona uphawu lwesantya sevili lwamavili amane ngeli xesha, kwaye emva koko uyithumele kwi-VCU (umlawuli wesithuthi), iyunithi yokulawula i-VCU iya kuhlalutya le miqondiso ukuze inqume imeko yesithuthi ngeli xesha, kwaye i-VCU ithumela umyalelo wokulawula uxinzelelo lwe-brake kwi-ABS yokulawula uxinzelelo (ipompo ye-ABS).
Xa isilawuli soxinzelelo lwe-ABS sifumana umyalelo wolawulo loxinzelelo lwe-brake, lulawula ngokuthe ngqo okanye ngokungathanga ngqo ukunyanzeliswa kwe-brake yetshaneli nganye ngokulawula ivalve yangaphakathi ye-solenoid yolawulo loxinzelelo lwe-ABS, ukuze kuhlengahlengiswe i-torque yokunyathela yamavili amane, ukuze ilungelelanise ukuncamathela komhlaba, kwaye uthintele ivili ekubeni litshixiwe ngenxa yamandla okuqhobosha ngokugqithisileyo.
Abaqhubi abaninzi abadala ababona apha banokucinga ukuba sihlala siqhuba "i-spot brake" inokudlala i-anti-lock effect. Kufuneka igxininiswe apha into yokuba le ngcamango iphelelwe lixesha, kwaye kungade kuthiwe indlela ye-"spot brake" i-intermittent braking iluchaphazele ukhuseleko lokuqhuba.
Kutheni usitsho lonto? Oku kukuqala kwimvelaphi ye "spot brake", ebizwa ngokuba "i-spot brake", ayixhotyiswanga nge-ABS anti-lock system kwisithuthi ngokunyathela ngokunyathekileyo kwi-pedal operation engapheliyo ye-pedal, ukuze ivili braking force ngamanye amaxesha hayi, ukuze kuthintelwe ifuthe lokutshixa ivili. Kufuneka kuqatshelwe apha ukuba ngoku isithuthi sinayo yonke inkqubo ye-anti-lock ye-ABS, iimpawu ezahlukeneyo zenkqubo yokuvala i-lock iya kuba nentlukwano ethile, kodwa ngokusisiseko unokwenza umqondiso wokufumanisa 10 ~ 30 amaxesha / okwesibini, inani lokuqhawula i-70. ~ Amaxesha angama-150 / i-frequency yokubulawa kwesibini, le mbono kunye nokubulawa rhoqo akunakwenzeka ukufikelela.
ABS anti-lock isiqhoboshi inkqubo kufuneka ibe kwi isiqhoboshi eqhubekayo ukudlala ngempumelelo umsebenzi wayo. Xa "i-spot-brake" sinyanzeliswa ukuba sinyanzelise ukunyathela, inkqubo ye-ABS yokunqanda ukutshixa ifumana umqondiso wokubhaqa amaxesha ngamaxesha, kwaye i-ABS ayiyi kukwazi ukusebenza ngokufanelekileyo, okuya kukhokelela ekunciphiseni ukunyanzeliswa kwe-braking kunye nomgama omde kakhulu wokuqhobosha. .
