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 ivili ukuba livalwe ngenxa yokunyanzeliswa kwe-braking force kwimeko yongxamiseko ye-braking yesithuthi, okubangela ukuba isithuthi siphulukane nolawulo lwesixhobo. 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 engxamisekileyo, ngenxa yokuba amandla okunyathela amavili amane afanayo, ukukhuhlana kwevili emhlabeni kuyafana, ngeli xesha isithuthi siya kuba nzima kakhulu ukujika, kwaye kulula ukubangela ingozi yesithuthi esilahlekileyo. 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 ukuphulwa, isantya sesantya sevili siya kukhangela isantya sesondo samavili amane ngeli xesha, kwaye emva koko siyithumele kwi-VCU (umlawuli wemoto), iyunithi yokulawula i-VCU iya kuhlalutya le miqondiso ukufumanisa imeko yesithuthi ngeli xesha, kwaye emva koko i-VCU ithumela umyalelo wokulawula uxinzelelo lwe-brake kwi-ABS yokulawula uxinzelelo (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 kulungiswe i-torque yokunyathela yamavili amane, ukuze ilungelelanise ukunamathela emhlabeni, kwaye ithintele ivili ukuba litshixiwe ngenxa yokunyanzeliswa ngamandla okunyathela.
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 ukusuka kwimvelaphi ye "spot brake", ebizwa ngokuba yi "spot brake", ayixhotyiswanga nge-ABS anti-lock system kwisithuthi ngokunyathela ngokunyanzeliswayo kwi-discontinuous brake operation ye-pedal, ukuze ivili lokuqhawula ivili ngamanye amaxesha akukho, ukwenzela ukuba kuthintelwe umphumo wokutshixa ivili. Kufuneka kuqatshelwe apha ukuba ngoku isithuthi sinayo yonke inkqubo ye-ABS ye-anti-lock, iimpawu ezahlukeneyo zenkqubo yokuvala i-lock iya kuba nentlukwano ethile, kodwa ngokusisiseko inokwenza umqondiso wokubona amaxesha angama-10 ~ 30 / okwesibini, inani lokunyathela ama-70 ~ 150 amaxesha / okwesibini ukubulawa, lo mbono kunye nokuphindaphinda kokubulawa akunakwenzeka ukufikelela.
ABS anti-lock isiqhoboshi inkqubo kufuneka ibe kwi isiqhoboshi eqhubekayo ukudlala ngempumelelo umsebenzi wayo. Xa "i-spot-brake" sinyanzeliswa ngokunyanzeliswa kwe-braking intermittent, i-ABS anti-lock system ye-anti-lock ifumana umqondiso wokubhaqa amaxesha ngamaxesha, kwaye i-ABS ayiyi kukwazi ukusebenza ngokufanelekileyo, okuya kukhokelela ekunciphiseni ukunyanzeliswa kwe-braking kunye nomgama omde kakhulu wokuqhawula.
