I-ABS Sensor yangaphambili: Umlondolozi oPhambili woKhuseleko lweeBrake kwiimoto
Kwinkqubo yokhuseleko lokubhuleka kwemoto, isenzi se-ABS esingaphambili sifana "nesiphelo semithambo-luvo" esibuthathaka, sikhusela ukhuseleko lokuqhuba ngokuzolileyo. Isenokubonakala ingabalulekanga, kodwa idlala indima engenakutshintshwa ngamaxesha abalulekileyo afana nokubhuleka okungxamisekileyo, kwaye ikwanokungaphumeleli ngenxa yezizathu ezahlukeneyo, ezichaphazela ukusebenza kokubhuleka kwesithuthi.
Umsebenzi oyintloko wesenzi se-ABS esingaphambili
I-sensor ye-ABS engaphambili yinxalenye ebalulekileyo yenkqubo yokuqhobosha imoto (i-ABS), efakwe kakhulu kumavili angaphambili. Umsebenzi wayo ophambili ujikeleze ukhuseleko lweebhuleki.
Okokuqala, sisibonisi sesantya sevili esisebenza ngexesha langempela. Ngokusebenzisa amawaka eenguqu ngomzuzwana wokujonga isantya, isibonisi se-ABS sangaphambili sinokubamba ngokuchanekileyo imeko yokujikeleza kwamavili angaphambili kwaye siguqule isignali yesantya ibe sisignali yombane ukuze idluliselwe kwiyunithi yolawulo lwe-elektroniki yesithuthi (ECU). Ngexesha lokuqhobosheka kongxamiseko, i-ECU isebenzisa ezi zibonakaliso ukumisela ukuba amavili aza kuqhobosheka na, kwaye ilawule ngokuchanekileyo amandla okuqhobosheka ukuze iphephe ukulahlekelwa yintambo ngenxa yokuqhobosheka, ithintele imoto ekutyibilikeni okanye ekulahlekelweni lulawulo. Umzekelo, kwiindlela ezityibilikayo, ukuqhobosheka kongxamiseko kunokubangela ukuba amavili angaphambili aqhobosheke ngokulula, kwaye isibonisi se-ABS sangaphambili sinokuqonda ngokukhawuleza kwaye sinike ulwazi, sivumela inkqubo ye-ABS ukuba ilungise ngokukhawuleza amandla okuqhobosheka, igcine imoto ikwindlela yokuqhuba ezinzileyo.
Okwesibini, ngumboneleli wedatha kwiinkqubo ezininzi zokhuseleko. Ngaphandle kokukhonza inkqubo ye-ABS, idatha yesantya sevili enikezelwa sisivamvo se-ABS esingaphambili ikwabalulekile ekusebenzeni okuqhelekileyo kweenkqubo ezifana ne-ESP (iNkqubo yoZinzo lwe-Electronic) kunye ne-TCS (iNkqubo yoLawulo lweTraction). Inkqubo ye-ESP ithelekisa umahluko wesantya phakathi kwamavili angaphambili nangasemva ukuze ibone ukuba imoto ifumana umkhwa wokutyibilika kwaye ingenelele ngokukhawuleza; inkqubo ye-TCS imisela ukuba amavili okuqhuba ayatyibilika na ngokusekelwe kwidatha yesantya sevili, ngaloo ndlela ilungisa amandla okukhupha. Ngokwenyani, isivamvo se-ABS esingaphambili sibonelela ngolwazi olusisiseko nolubalulekileyo lwemeko yokuqhuba isithuthi kwezi nkqubo, sakha kunye inethiwekhi yokhuseleko lwesithuthi.
Kwezinye iimodeli, isenzi se-ABS esingaphambili sikwathatha umsebenzi wokubona isantya. Siguqula isignali yesantya sevili esijongiweyo sibe lulwazi lwesantya sesithuthi kwaye siyibonise kwideshibhodi yesithuthi, nto leyo evumela umqhubi ukuba azi isantya sesithuthi ngexesha langempela. Kwezinye iimodeli ezinesenzi esingathanga ngqo soxinzelelo lwetayara, isenzi se-ABS esingaphambili simisela ngokungathanga ngqo ukuba uxinzelelo lwetayara luqhelekile na ngokujonga umahluko omncinci kwisantya setayara, songeza olunye ungqimba lokhuseleko lokuqhuba.
Iimpazamo eziqhelekileyo kunye nezizathu ze-sensor ye-ABS yangaphambili
Nangona isenzi se-ABS esingaphambili sibaluleke kakhulu, sikwanokungasebenzi kakuhle ngenxa yezizathu ezahlukeneyo. Iimpazamo eziqhelekileyo kunye nezizathu ziquka oku kulandelayo.
Okokuqala, ukungenelela kothuli. Uthuli lwesinyithi oluvela kwiibrake pads ezigugileyo lolona "bulala" luphambili kwi-sensor ye-ABS yangaphambili. Ngexesha lokusebenza kwesithuthi, uthuli lwesinyithi oluvela kwiibrake pads ezigugileyo luya kunamathela kwintloko ye-sensor. Ingakumbi kwimozulu yemvula okanye emva kokudlula kwiindawo ezinodaka, olu thuli luya kudibana nodaka namanzi, lwenze amasuntswana emagnethi agquma intloko ye-sensor, nto leyo echaphazela ukuhanjiswa kwayo kwesiginali. Umzekelo, iMercedes-Benz S-Class eFoshan emva kwexesha lemvula yafumana ii-alamu ze-ABS ezihlala zihleli ngenxa yokuba intloko ye-sensor ye-ABS yangaphambili igqunywe ngamasuntswana emagnethi, kwaye ingxaki yasonjululwa emva kokucoca.
Okwesibini, iingxaki zocingo. Ucingo lwe-sensor ye-ABS yangaphambili lubonakala kwindawo yokusebenza kwesithuthi esintsonkothileyo kwaye lunobunzima bokuqhagamshelana ngenxa yokungcangcazela okuvela ekumisweni nasekufakweni kwe-oxidation. Xa kuvavanywa iToyota Corolla, kwafunyaniswa ukuba unxibelelwano lwe-sensor yevili lasekunene langaphambili lubangelwe kukungcangcazela kokumisiweyo, okubangela ukumelana konxibelelwano lwe-20Ω, ngaphezulu kakhulu kwexabiso eliqhelekileyo ≤ 0.5Ω, okuya kubangela ukudluliselwa kwesignali okungazinzanga kunye nokuphazamiseka, okubangela ukusilela kwenkqubo ye-ABS.
Okwesithathu, ukuguga kwezixhobo. Indawo yokusebenza kwesithuthi iyinkimbinkimbi, kwaye ubushushu obuphezulu kwindawo yenjini bunokubangela umonakalo kwimagnethi esisigxina ye-sensor ye-ABS yangaphambili. Uvavanyo lokuqina eHainan lubonise ukuba xa isebenza rhoqo kwindawo engama-80℃ kangangeeyure ezingama-2000, ukuhamba kwemagnethi yemagnethi esisigxina kwisensor kwehla ngaphezulu kwama-35%, nto leyo eya kukhokelela ekwehleni kokuchaneka kokufunyanwa kwesignali yesensor kwaye yenze ukuba ingakwazi ukubonisa ngokuchanekileyo ulwazi lwesantya sevili.
Okwesine, umonakalo weringi yegiya. Ukuba iringi yegiya, esebenza kunye nesensor ye-ABS yangaphambili, inamazinyo angekhoyo, umhlwa, okanye amatye anamathele kuyo, iya kubangela ukuba isensor ifumane imiqondiso engapheliyo. UWuling Hongguang wakha waba nengxaki apho iringi yegiya engaphambili yayinamatshe anamathele kuyo, nto leyo eyabangela ukuba i-ECU ifumane isignali yesantya esingenanto semizuzwana eyi-0.5, eyabangela ngokuthe ngqo ukhuseleko lwe-ABS kwaye yachaphazela ukuqhuba okuqhelekileyo kwesithuthi.
Okwesihlanu, umbane ongaqhelekanga. Ukutshintshatshintsha kwevolthi kuyingozi ngaphezu kokunqongophala kwamandla. Ukuba ivolthi ephezulu yenkqubo iphezulu kakhulu ngenxa yeziphene kumlawuli wejenereyitha wesithuthi okanye ezinye izizathu, inokutshisa isenzi se-ABS esingaphambili. I-BMW X5 yakha yaba nengxaki apho umlawuli wejenereyitha wasilela khona, nto leyo eyabangela ukuba ivolthi ephezulu yenkqubo ifikelele kwi-16V, yaza yatshisa iisenzi ze-ABS ezimbini ezingaphambili.
Iingozi kunye nezisombululo zokungaphumeleli kwe-sensor ye-ABS yangaphambili
Xa isibane se-ABS esikwideshibhodi yesithuthi sikhanya, okanye ukuba kukho ukwehla kokusebenza kokubhuleka, ukungcangcazela okungaqhelekanga kwepedali yebrake, njl.njl., kuyimfuneko ukujonga ngokukhawuleza isenzi se-ABS esingaphambili. Okokuqala, kunokwenziwa ukucoca okusisiseko, kusetyenziswa isibhamu somoya ukuvuthela isenzi kwi-engile efanelekileyo ukuze kuthintelwe ukungcola ukuba kungangeni kwi-bearing, kunye nokusebenzisa iarhente yokucoca ekhethekileyo ukunyibilikisa amabala eoli yemagnethi; okwesibini, jonga uqhagamshelo lwemigca, kusetyenziswa i-multimeter ukulinganisa ukumelana komgca ukuqinisekisa unxibelelwano oluhle; ukuba kungenxa yokuguga okanye umonakalo wenxalenye, kuyimfuneko ukutshintsha isenzi ngexesha; ngomonakalo weringi yegiya kunye neengxaki zombane ezingaqhelekanga, kufuneka kwenziwe ukulungiswa kunye nonyango olujoliswe kuko.
Ukuqukumbela, isenzi se-ABS esingaphambili singumgcini oyintloko wokhuseleko lokubhuleka kwiimoto. Ukuqonda umsebenzi waso, izizathu zempazamo, kunye neendlela zokuphendula kunokusinceda silondoloze ngcono inkqubo yokubhuleka kwesithuthi kwaye siqinisekise ukhuseleko lokuqhuba.
