Nheyo uye kushandiswa kwemotokari abs sensor
Iyo yekushanda nheyo yemotokari abs ndeiyi:
Muchimbichimbi braking, uchitsamira pane yakanyanya kunzwa vhiri yekumhanyisa sensor yakaiswa pavhiri rega rega, kukiya kwevhiri kunowanikwa, uye komputa inodzora nekudzvanya regulator kuti ibvise kudzvanywa kwepombi yebhureki yevhiri kudzivirira kukiya kwevhiri. Iyo abs system ine abs pombi, vhiri kumhanya sensor uye brake switch.
Basa re abs system ndeiyi:
1, dzivirira kurasikirwa kwemotokari, wedzera chinhambwe chebhureki, vandudza kuchengetedzeka kwemotokari;
2, kunatsiridza mabhureki emotokari;
3, kudzivirira vhiri mukugadzirisa mabhureki;
4. Iva nechokwadi chekuti mutyairi anokwanisa kudzora kwaakananga kana achinge aita mabhureki uye kudzivirira ekisero yekumashure kuti isatsvedza.
Basa reABS, sekureva kunoita zita, basa guru reiyo anti-lock braking system ndere kudzivirira vhiri kuvharika nekuda kwekunyanya kuvharika simba kana paine emergency braking yemotokari, zvichiita kuti mota irasikirwe nekutonga. mudziyo. Semuenzaniso, kana tawana chipingamupinyi pamberi pedu, mota ine ABS system inokwanisa kufambisa zviri nyore kudzivirira bhureki rekukurumidzira panguva imwe chete.
Kana mota isina kurongedzerwa neABS system mu emergency braking, nekuti simba rekubhureki remavhiri mana rakafanana, kukwenya kwevhiri pasi kwakangofanana, panguva ino mota ichave yakaoma zvakanyanya kutendeuka. , uye zviri nyore kukonzeresa njodzi yemotokari kutadza kutonga. Zvakakwana kuti uone kukosha kweiyo ABS system kukuchengetedza kwedu kutyaira. Isu hatifanirwe kunetsekana neizvi, ikozvino chiyero chenyika chakamanikidza makambani emotokari munzira yekugadzira mota inofanirwa kuve yakajairwa ABS anti-lock system.
Saka ABS anti-lock braking system inoshanda sei? Tisati tanzwisisa nheyo yayo yekushanda, tinofanira kutanga tanzwisisa zvikamu zveABS anti-lock system, ABS inonyanya kuumbwa nevhiri rekumhanya sensor, electronic control unit, brake hydraulic regulator, brake master cylinder nezvimwe zvikamu. Kana mota ichida kubhureki, vhiri rekumhanya sensor pavhiri rinoona vhiri rekumhanya chiratidzo chemavhiri mana panguva ino, uye wozotumira kuVCU (mutongi wemotokari), iyo VCU control unit inoongorora aya masaini kuti aone. mamiriro emotokari panguva ino, uyezve VCU inotumira murairo webrake pressure control command kune ABS pressure regulator (ABS pombi).
Kana iyo ABS pressure regulator inogamuchira rairo yebrake pressure control control, inodzora zvakananga kana zvisina kunanga kudzvanywa kwebrake yega yega nekudzora mukati solenoid valve yeABS pressure regulator, kuitira kugadzirisa braking torque yemavhiri mana, kuti gadzirisa kune pasi adhesion, uye kudzivirira vhiri kubva kukiyiwa nekuda kwekunyanyisa braking simba.
Vazhinji vatyairi vekare vanoona pano vangafunga kuti isu tinowanzo kutyaira "spot brake" inogona kutamba anti-lock effect. Zvinoda kusimbiswa pano kuti pfungwa iyi ndeyechinyakare, uye zvinogona kutaurwa kuti nzira ye "spot brake" intermittent braking yakanganisa kuchengetedza kwekutyaira.
Sei uchidaro? Izvi ndezvekutanga kubva kwakabva "spot brake", iyo inonzi "spot brake", haina kugadzirwa neABS anti-lock system pamotokari nekutsika-tsika pane inomira bhureki kushanda kwepedal, kuitira kuti vhiri braking simba dzimwe nguva kwete, kuitira kudzivirira kuitika kwevhiri kukiya. Zvinofanira kucherechedzwa pano kuti ikozvino mota ine ese akajairwa ABS anti-lock system, akasiyana mabhureki e-anti-lock system achave nemisiyano, asi zvakanyanya anogona kuita chiratidzo chekuona 10 ~ 30 nguva / yechipiri, nhamba yekubhureki makumi manomwe. ~ 150 nguva / yechipiri execution frequency, iyi maonero uye execution frequency haigone kusvika.
ABS anti-lock braking system inofanirwa kunge iri mukuenderera mberi braking kuti itambe basa rayo zvinobudirira. Kana isu tichiita "spot-brake" yepakati mabhureki, iyo ABS anti-lock braking system inogamuchira chiratidzo chekuona nguva nenguva, uye ABS haizokwanise kushanda nemazvo, izvo zvinozotungamira mukuderedzwa kwebhureki uye kunyangwe kureba kwebhureki kureba. .
