Kukhazikitsa Chowonjezera cha Vacuum cha Magalimoto: Choteteza Choyambira ndi Kuyankha Kolakwika mu Dongosolo la Mabuleki
Mu "banja" la dongosolo la mabuleki agalimoto, chowonjezera cha vacuum chimaonedwa ngati chiwalo chodzichepetsa koma chofunikira kwambiri. Chili ngati chifaniziro champhamvu chobisika kuseri kwa zochitika, kuteteza mwakachetechete ntchito iliyonse ya mabuleki a dalaivala. Sikuti chimangochepetsa katundu wa dalaivala komanso chimamanga mzere wofunikira kwambiri wotetezera kuyendetsa galimoto.
Ntchito yaikulu ya msonkhano wowonjezera vacuum
Kutseka bwino, kuchepetsa katundu wogwirira ntchito Ntchito yodziwika bwino ya chowonjezera cha vacuum ndikukwaniritsa kutseka bwino. Chimagwiritsa ntchito 50 - 80 kPa ya vacuum negative pressure yopangidwa ndi manifold ya injini kapena pampu yamagetsi ya vacuum. Dalaivala akamayendetsa pedal ya brake, diaphragm ya chipinda cha servo imapanga kusiyana kwa kupsinjika mbali zonse ziwiri, motero imapanga 600 - 1200 N thrust, yomwe imayikidwa pamwamba pa kupsinjika kwa phazi la dalaivala, kuchepetsa mphamvu ya pedal ndi 40% - 70%. Mwachitsanzo, dalaivala amafunikira mphamvu ya mapazi 10 kg yokha kuti akwaniritse mphamvu yofanana ndi 30 kg ya brake effect yeniyeni, yomwe ndi yabwino kwambiri kwa oyendetsa azimayi kapena ofooka mwakuthupi, zomwe zimachepetsa kutopa mwakuthupi panthawi yoyendetsa mota nthawi yayitali.
Chitsimikizo cha chitetezo cholephera, kupulumuka pazochitika zoopsa kwambiri Ngati dongosolo la vacuum lalephera, ntchito yotsimikizira chitetezo cholephera ya vacuum booster assembly idzayamba kugwira ntchito. Pakadali pano, chopondera chopondera chowongolera chidzakankhira mwachindunji ndodo yayikulu ya silinda kudzera mu kapangidwe ka makina. Ngakhale mphamvu yofunikira pa pedal ya brake idzawonjezeka kwambiri kuchokera pa 80 - 150 N wamba mpaka 300 - 500 N, mphamvu yoyambira ya braking ikadalipo, mogwirizana ndi muyezo wachitetezo wofunikira wadziko lonse (GB 21670 - 2008). Kapangidwe kameneka kamatsimikizira kuti galimotoyo imatha kusunga mphamvu yoyambira ya braking pazochitika zoopsa kwambiri, kupatsa madalaivala nthawi yamtengo wapatali yogwirira ntchito mwadzidzidzi.
Kuwongolera mayankho nthawi yeniyeni, kulondola bwino kwa mabuleki. Imagwiritsa ntchito kapangidwe ka ma valve awiri, komwe kumatha kumaliza kusintha kwa njira ya vacuum mkati mwa masekondi 0.1 - 0.3. Kuchedwa kwa thandizo la mabuleki kumakhala kotsika kuposa malire apadziko lonse lapansi a 200 ms, kuonetsetsa kuti ntchito ya mabuleki iyankhidwa mwachangu. Disiki yolimbana ndi rabara yamkati imatha kusamutsa 85% - 95% ya mphamvu ya servo ndipo nthawi yomweyo imapatsa dalaivala mayankho a mphamvu ya pedal, kuthandiza dalaivala kuzindikira mphamvu ya mabuleki molondola, ndikukweza kulondola kwa ntchito ya mabuleki. Pa mitundu yamagalimoto amagetsi, pampu yamagetsi ya vacuum yomwe yayikidwa imathanso kukwaniritsa zofunikira ziwiri za makina obwezeretsa mphamvu ndi makina achikhalidwe a mabuleki, kukonza magwiridwe antchito a mabuleki agalimoto komanso kugwiritsa ntchito mphamvu moyenera.
Zolakwika ndi mayankho wamba a msonkhano wowonjezera vacuum
Choponda cha mabuleki chimakhala cholimba, kukana kwa mabuleki kumawonjezeka. Izi ndi zolakwika zomwe zimachitika kawirikawiri, zomwe nthawi zambiri zimasonyeza vuto lotseka mu vacuum system, mwina chifukwa cha kutuluka kwa chitoliro cha vacuum, kukalamba ndi kuonongeka kwa mphete yotsekera pampu ya vacuum, ndi zina zotero. Izi zikachitika, dalaivala adzamva kuti kutseka kuli ngati kuponda "miyala yolimba", yomwe imafuna khama lalikulu. Yankho lake ndikupita mwachangu ku malo okonzera akatswiri kuti akawone ngati chitoliro cha vacuum, pampu ya vacuum, ndi chowonjezera chokha, ndikusintha mphete yotsekera yowonongeka kapena kukonza chitoliro chotuluka.
Kubwerera kosayenera kwa pedal ya brake Ngati pedal ya brake ibwerera pang'onopang'ono kapena ikulephera kubwerera itatha kugwedezeka, mwina pali vuto la makina mu kapangidwe ka mkati mwa booster, monga kugwedezeka kwa zigawo kapena kuwonongeka. Izi zidzakhudza kubwezeretsedwa kwabwino kwa dongosolo la braking ndikuwonjezera zoopsa zoyendetsera. Pakukonza, cholumikizira cha booster chiyenera kuchotsedwa kuti chiyang'ane zigawo zamkati za makina, mafuta odzaza zigawo kapena kusintha zigawo zowonongeka.
Kuchuluka kwa mtunda woyimitsa, kuchepa kwa magwiridwe antchito a braking Pamene chothandizira cha vacuum sichikupereka chithandizo chokwanira, mphamvu ya braking idzachepa kwambiri, ndipo mtunda woyimitsa udzawonjezeka kwambiri. Vutoli lingayambitsidwe ndi kulephera kwa injini ya vacuum pump kapena electronic delay module, kulephera kwa pressure switch kapena pressure switch line, ndi zina zotero. Ogwira ntchito yokonza amatha kuwerenga khodi ya cholakwika ndi kuyenda kwa deta polumikiza chida chowunikira kuti awone momwe ntchito ikuyendera, mphamvu yogwira ntchito komanso kuchuluka kwa mphamvu ya vacuum system ya vacuum pump, kudziwa malo enieni olakwika ndikusintha zigawo zogwirizana. Phokoso la mabuleki ndi kugwedezeka kwa galimoto Panthawi yoyimitsa, ngati pali phokoso losazolowereka kapena kugwedezeka kwa galimoto, kungakhale chifukwa cha kuwonongeka kwa zigawo zamkati za chilimbikitso kapena kulephera kwa chilimbikitso cha vacuum, zomwe zimayambitsa mphamvu yosagwirizana ya braking. Pakadali pano, ndikofunikira kuyang'ana mwachangu kuwonongeka kwa zigawo zamkati za chilimbikitso, kusintha zigawo zomwe zawonongeka kwambiri, komanso kuwona ngati pali kutuluka kwa mpweya mu vacuum system kuti muwonetsetse kuti mphamvu yoyimitsa yofanana komanso yokhazikika.
Ngakhale kuti cholumikizira chowonjezera mpweya chimabisika mkati mwa galimoto, chimagwirizana mwachindunji ndi chitetezo choyendetsa galimoto komanso luso loyendetsa galimoto. Oyendetsa galimoto akamagwiritsa ntchito galimoto tsiku lililonse, ayenera kusamala ndi zizindikiro zachilendo za dongosolo loyendetsera mabuleki ndikuyang'ana nthawi zonse ndikusunga cholumikizira chowonjezera mpweya. Ngati pali mavuto aliwonse, ayenera kuthetsedwa mwachangu, kuti "chotetezera kumbuyo" ichi chigwire ntchito bwino nthawi zonse ndikuwonetsetsa kuti ulendo uliwonse uli wotetezeka.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
