Kubatanidzwa kweVacuum Booster yeMotokari: Core Defender uye Mhinduro Yezvikanganiso muBrake System
Mu "mhuri" yehurongwa hwemabhureki emotokari, vacuum booster assembly inoonekwa senhengo inozvininipisa asi isingakoshi. Yakafanana nechinhu chine simba chakavanda kuseri kwezviitiko, chichichengetedza chinyararire mashandiro ese ebhureki emutyairi. Hazvingoderedzi mutoro wemutyairi chete asiwo zvinovaka tambo yekudzivirira yakakosha yekuchengetedza kutyaira.
Basa guru remuchina wekusimbisa vacuum
Kubhureka zvinobudirira, mutoro wekushanda wakaderera Basa rakajeka rekubatanidza vacuum booster nderekuita kuti bhureka rishande zvakanaka. Rinoshandisa 50 - 80 kPa ye vacuum negative pressure inogadzirwa ne engine intake manifold kana electric vacuum pump. Kana mutyairi akakwira pa brake pedal, diaphragm ye servo chamber inoita musiyano wekumanikidzwa kumativi ese, nokudaro ichigadzira 600 - 1200 N thrust, iyo inoiswa pamusoro pekumanikidzwa kwetsoka yemutyairi, ichideredza simba re pedal ne40% - 70%. Semuenzaniso, mutyairi anongoda 10 kg yesimba retsoka chete kuti awane yakaenzana ne30 kg yemhedzisiro chaiyo yekubhureka, iyo inonyanya kubatsira kune vatyairi vechikadzi kana vasina simba mumuviri, zvichideredza kuneta mumuviri panguva yekutyaira kwenguva refu.
Vimbiso yekuchengetedzeka yekukundikana, kurarama mumamiriro ezvinhu akaomarara. Kana system ye vacuum ikakundikana, basa rekuchengetedza kukundikana kwe vacuum booster assembly richatanga kushanda. Panguva ino, control valve push rod ichasunda zvakananga main cylinder push rod kuburikidza nechimiro chemuchina. Kunyangwe simba rinodiwa pabrake pedal richizowedzera zvakanyanya kubva pa 80 - 150 N kusvika 300 - 500 N, simba rekubhureka richiripo, zvichienderana nemutemo wekuchengetedza wenyika (GB 21670 - 2008). Dhizaini iyi inoita kuti mota ikwanise kuchengetedza kugona kwekubhureka mumamiriro ezvinhu akaomarara, zvichipa vatyairi nguva inokosha yekubata nekukurumidza.
Kudzora mhinduro panguva chaiyo, kunatsiridza kurongeka kwebhureki. Inoshandisa chimiro chemavharuvhu maviri, chinogona kupedzisa kuchinja kwenzira ye vacuum mukati memasekonzi 0.1 - 0.3. Kunonoka kwekubatsira kubhureki kwakaderera pane chiyero chepasi rose che200 ms, zvichiita kuti kupindura kwekushanda kwebhureki kuitwe nekukurumidza. Disc remukati rerabha rinogona kutamisa 85% - 95% yesimba reservo uye panguva imwe chete kupa mutyairi mhinduro yesimba re pedal, zvichibatsira mutyairi kuona simba rebhureki nemazvo, zvichivandudza kurongeka kwekushanda kwebhureki. Kune mota dzemagetsi, pombi yemagetsi yekuputira yakaisirwa inogonawo kusangana nezvinodiwa zviviri zvesystem yekudzoreredza simba uye system yebhureki yechinyakare, ichivandudza mashandiro ebhureki yemotokari uye kushanda zvakanaka kwesimba remagetsi.
Zvikanganiso zvakajairika uye mhinduro dzegungano rekusimbisa vacuum
Pedal yemabhureki inooma, kuramba kwebhureki kwakawedzera. Izvi zvinowanzo ratidza dambudziko rekuvharwa kwemuchina wevacuum, zvichida zvichikonzerwa nekubuda kwepombi yevacuum, kukwegura uye rin'i yevhamu yemuchina wevacuum yakakuvara, nezvimwewo. Kana izvi zvikaitika, mutyairi achanzwa kuti rin'i yebhureki yakafanana nekutsika "matombo akaoma", zvinoda kushanda nesimba. Mhinduro ndeyekuenda nekukurumidza kunzvimbo yekugadzirisa yehunyanzvi kuti utarise kuvharwa kwepombi yevacuum, pombi yevacuum, uye booster pachayo, uye kutsiva rin'i yevhamu yakakuvara kana kugadzirisa pombi iri kudonha.
Kudzoka kusina kujairika kwepedal yebhureki Kana pedal yebhureki ichidzoka zvishoma nezvishoma kana ikatadza kudzoka mushure mekuora mwoyo, zvingangoita kuti pane kutadza kwemuchina muchimiro chemukati chebooster, senge kuvharika kwezvikamu kana kukuvara. Izvi zvinokanganisa kudzorerwa kwesystem yebhureki kwakajairika uye zvinowedzera njodzi dzekutyaira. Panguva yekugadzirisa, booster assembly inofanirwa kupatsanurwa kuti iongorore zvikamu zvemukati zvemakinika, kudira mafuta zvikamu zvakavharika kana kutsiva zvikamu zvakakuvara.
Kureba kwebhureki, kudzikira kwekushanda kwebhureki Kana vacuum booster assembly ikatadza kupa rubatsiro rwakakwana, simba rebhureki richadzikira zvakanyanya, uye daro rebhureki richawedzera zvakanyanya. Kukanganisa kunogona kukonzerwa nekukundikana kwemota yepombi yevacuum kana electronic delay module, kukundikana kwe pressure switch kana pressure switch line, nezvimwewo. Vashandi vekugadzirisa vanogona kuverenga fault code uye data flow nekubatanidza chishandiso chekuongorora kuti vaone mamiriro ekushanda, kushanda kwe current uye vacuum system pressure value yepombi yevacuum, kuona nzvimbo chaiyo yekukanganisa uye kutsiva zvikamu zvinoenderana. Ruzha rwebhureki nekudedera kwemotokari Munguva yekubhureki, kana paine ruzha rusina kujairika kana kuzunguzika kwemotokari, zvinogona kunge zvichikonzerwa nekusakara kwezvikamu zvemukati zve booster kana kusashanda zvakanaka kwe vacuum booster, zvichikonzera kusaenzana kwesimba rebhureki. Panguva ino, zvakakosha kuti utarise nekukurumidza kusakara kwezvikamu zvemukati zve booster, kutsiva zvikamu zvakasakara zvakanyanya, uye zvakare kutarisa kana paine mhepo inobuda mu vacuum system kuti uve nechokwadi chekuti simba rebhureki rakaenzana uye rakagadzikana.
Kunyangwe chibatiso chevacuum booster chakavanzwa mukati memotokari, chine chekuita zvakananga nekuchengetedzeka kwekutyaira uye ruzivo rwekutyaira. Kana vatyairi vachishandisa mota zuva nezuva, vanofanira kutarisisa zviratidzo zvisina kujairika zvehurongwa hwemabhureki uye kugara vachiongorora nekugadzirisa chibatiso chevacuum booster. Kana paine matambudziko akawanikwa, anofanira kugadziriswa nekukasika, kuitira kuti "backing guard" iyi igone kugara ichishanda zvakanaka uye kuve nechokwadi chekuchengetedzwa kwerwendo rwese.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
