Mfundo ya vacuum booster.
Chowonjezera cha vacuum chimagwiritsa ntchito vacuum (negative pressure) kuti iwonjezere mphamvu ya dalaivala pa pedal, motero amakulitsa mphamvu ya braking. Mfundo yeniyeni yogwirira ntchito ndi iyi:
Injini ikamathamanga, pampu ya brake booster imapanga chopukutira mbali imodzi ya chilimbikitso poyamwa mpweya, zomwe zimapanga kusiyana kwamphamvu ndi kuthamanga kwa mpweya wabwino mbali inayo. Kusiyana kwapanikiziku kumapangitsa kuti diaphragm isunthire kumapeto kwa kuthamanga kwapansi, motero kukankhira ndodo ya pampu ya brake master.
Pogwira ntchito, kasupe wokhazikitsira ndodo imagwira ma brake pedal pamalo ake oyamba. Panthawiyi, valavu yoyang'ana pamalo olumikizira chubu ndi vacuum booster imatsegulidwa. Chidutswa mkati mwa chilimbikitso chimachigawa kukhala chipinda chenicheni cha mpweya ndi chipinda chogwiritsira ntchito mpweya, chomwe nthawi zambiri chimakhala chosiyana ndi dziko lakunja koma chimatha kulumikizidwa ndi mlengalenga ndi zipangizo ziwiri za valve.
Pamene dalaivala akukankhira pansi pa brake pedal, kachipangizo kameneka kamatseka vacuum valve, pamene valavu ya mpweya kumbali ina imatsegulidwa, kulola mpweya kulowa. Pansi pa kupanikizika koyipa, diaphragm imakokera kumapeto kwa pampu ya brake master, yomwe imayendetsa ndodo ndikukulitsa mphamvu ya mwendo.
Kapangidwe kameneka kamalola dalaivala kuwongolera kutsika kwagalimoto mosavuta pamene chopondapo cha brake chikanikizidwa, kuwongolera chitetezo chagalimoto.
Kodi vacuum booster ndiyosavuta kuthyoka?
Vuto la vacuum booster silosavuta kuwononga, bola ngati litayikidwa bwino ndikugwiritsidwa ntchito, limatha kugwira ntchito moyenera kwa nthawi yayitali. Komabe, momwe pampu ya vacuum booster imagwira ntchito imatha kukhudzidwa ndi zinthu zingapo, kuphatikiza momwe galimoto imagwiritsidwira ntchito, zinthu zachilengedwe, komanso ngati kukonza ndi kukonza nthawi zonse kumachitika.
Kugwiritsa ntchito ndi kukonza moyenera: Malingana ngati galimotoyo nthawi zambiri imakhala yoyendetsa kwambiri (monga kutentha kwapamwamba, chinyezi chambiri kapena kugunda kwakukulu), kapena galimotoyo siisungidwa nthawi zonse, mapampu olimbikitsa amatha kukhala ndi mavuto. Chifukwa chake, kukhazikitsa kolondola, kugwiritsa ntchito ndi kukonza pafupipafupi ndiye chinsinsi chothandizira kuti vacuum booster igwire bwino ntchito.
Zinthu zachilengedwe: Mphamvu ya vacuum booster imakhudzidwa kwambiri ndi zinthu zachilengedwe, monga kusowa kwa vacuum komwe kumachitika chifukwa choyendetsa pamalo okwera, komanso kusowa kwa vacuum chifukwa cha kuzizira koyambira. Zinthu zachilengedwezi ziyenera kuganiziridwa pakupanga ndi chitukuko, komanso pakugwiritsa ntchito galimoto tsiku ndi tsiku, mwiniwakeyo amafunikanso kukhala ndi chidziwitso chodzifufuza kuti athetse mavutowa.
Zolakwa zofala: Zolakwika zomwe zimachitika nthawi zambiri zimaphatikizapo kuwonongeka kwa vacuum booster check valve, komwe kungayambitse chisindikizo chotayirira, mabuleki olimba, komanso kuthamanga kosasunthika kopanda ntchito pamene mukuswa mabuleki. Komanso, kutayikira mafuta chodabwitsa ndi vuto wamba, pamene ananyema master mpope mafuta kutayikira, kupyolera mu mapeto a chisindikizo mafuta mozama chilimbikitso, kuchititsa vacuum booster diaphragm mapindikidwe, chisindikizo si okhwima, mphamvu dontho.
Pofuna kusunga bwino ntchito ya vacuum booster, tikulimbikitsidwa kuti mwiniwake ayang'ane ndi kusunga ma brake system panthawi yake pamene akugwiritsa ntchito galimoto nthawi wamba. Komanso, vacuum chilimbikitso mpope ndi mtundu wa mwatsatanetsatane mkulu ndi mpope tcheru, amene ayenera mosamalitsa kutsatira malamulo kondomu, fufuzani ngati ntchito ndi kondomu ndi zachilendo, ndi fufuzani ngati mpope ali kutayikira chodabwitsa. Ngati pampu ya vacuum booster sikugwiritsidwa ntchito kwa nthawi yayitali, siyenera kugwira ntchito mokwanira nthawi yomweyo ikagwiritsidwanso ntchito.
Vutoli lathyoka
Kuchita kwa vacuum booster yosweka makamaka kumaphatikizapo kusayenda bwino kwa braking kapena kusakhala ndi braking, kubwerera pang'onopang'ono kapena kusabwereranso, phokoso lodziwika bwino limamveka mukaponda pa brake pedal, komwe mungayendere mabuleki kapena kugwedezeka, komanso kumverera kwa brake pedal. zofewa. Zizindikirozi zikuwonetsa kuti chowonjezera cha vacuum chikhoza kukhala ndi vuto, monga kutuluka kwa mpweya kapena kuwonongeka, ndipo chiyenera kuyang'aniridwa ndi kukonzedwanso nthawi kuti zitsimikizire kuyendetsa galimoto.
Kufunika kwa vacuum booster ndikuti kumathandizira dalaivala kuti azitha kuwongolera mphamvu ya brake ndikuchepetsa mphamvu ya mabuleki a dalaivala, potero kumapangitsa kuti ma brake azigwira bwino ntchito komanso chitetezo. Chiwongolero cha vacuum chikalephera, monga kutayikira kwa mpweya, kungayambitse kuchepa kwakukulu kwa mabuleki, kapena kutayika kwathunthu kwa braking effect, kumawonjezera kwambiri chiwopsezo choyendetsa.
Kuchita kwa kutayikira kwa mpweya wa vacuum booster kungaphatikizepo kusayenda bwino kwa mabuleki, kubweza pang'onopang'ono kapena osachitapo ma brake, ndipo phokoso lodziwika bwino limamveka pambuyo pa kukanikizidwa kwa brake. Ngati zizindikirozi zapezeka, tikulimbikitsidwa kuti muyang'ane ndikukonza zowonjezera zowonjezera panthawi yake.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
