Ma brake pedal amalephera, ma brake fluid sachoka. Kuyang'ana zifukwa
Zamkatimu
Mpweya mu dongosolo
Mwina chomwe chimayambitsa kulephera kwa ma brake pedal ndi matumba a mpweya. Brake fluid imatanthawuza za media zosavomerezeka. Mpweya umakanizidwa mosavuta. Ndipo ngati mapulagi a gasi apangidwa mu ma brake system, ndiye mukasindikiza pedal, amangopanikiza. Ndipo mphamvu yochokera ku silinda ya master brake imaperekedwa pang'ono kwa ma calipers kapena masilindala ogwira ntchito.
Chodabwitsa ichi chingayerekezedwe ndi kuyesa kusuntha chinthu cholemera, kuchitapo kanthu mwachindunji, koma kupyolera mu kasupe wofewa. Kasupe adzapanikizidwa mpaka pamalo ena, koma chinthucho sichidzasuntha. Momwemonso ndi air brake system: mumakankhira pedal - mapepala samasuntha.
Pali zifukwa zingapo za izi. Chofala kwambiri ndi madzi akale, osasinthidwa kwa nthawi yayitali. Brake fluid ndi hygroscopic, kutanthauza kuti imatha kuyamwa chinyezi kuchokera mumlengalenga. Pamene kuchuluka kwa madzi mumadzimadzi kupitirira 3,5% ya voliyumu yonse, iyenera kusinthidwa. Popeza mukanikiza ndi brake pedal, imatha kuwira, zomwe zingapangitse mapangidwe a magalimoto.
Chifukwa chachiwiri ndi ma micropores mu brake force regulator, ma line articulations kapena actuating units (calipers ndi masilinda). Mosiyana ndi zomwe anthu ambiri amakhulupirira, pores oterowo nthawi zina amatha kuyamwa mpweya kuchokera ku chilengedwe, koma osatulutsa brake fluid. Zomwe zimabweretsa chisokonezo.
Njira yotulutsira izi ndi yosavuta: muyenera kusintha madzimadzi ngati ndi akale, kapena kutulutsa magazi. Kwa galimoto iliyonse, njira yake yopopera mabuleki. Kwenikweni, pamafunika anthu awiri kuti achite izi. Woyamba akukankhira pedal, wachiwiri amatsegula zopangira pazitsulo (calipers) ndiyeno ndikutulutsa magazi a brake fluid, kutulutsa mapulagi a gasi mu dongosolo. Pali njira zopopera mphamvu yokoka zomwe mnzako safunikira.
Silinda yayikulu ya brake ndiyopanda dongosolo
Yamphamvu ananyema waukulu, ngati dongosolo valavu apangidwe mmbuyo ndi magawano mu madera, ntchito pa mfundo ya ochiritsira hydrostatic pagalimoto. Monga syringe. Timakanikiza ndodo - pisitoni imakankhira madzi ndikupereka mokakamizidwa ku dongosolo. Ngati ma cuffs a pistoni atha, ndiye kuti madzi amadzimadzi amalowa mkati mwake. Ndipo izi zidzangopangitsa kuti pedal yolephereka komanso pafupifupi kulibe mabuleki. Izi zidzasunga madzi omwe ali m'malo mosungiramo.
Pali njira imodzi yokha yochotsera izi: kukonza kapena kusintha silinda ya brake. Kukonzekera kwa chinthu ichi cha dongosololi tsopano kukuchitika kawirikawiri ndipo sikupezeka kwa magalimoto onse. Kuphatikiza apo, zida zokonzekera kuchokera pagulu la ma cuffs sizimathetsa vutoli nthawi zonse. Nthawi zina pamwamba pa silinda amawonongeka ndi dzimbiri, zomwe sizimaphatikizapo kuthekera kokonzanso.
Kuvala kovuta kwa magawo a dongosolo
Chifukwa china cha kulephera kwa pedal ya brake kungakhale kuvala kofunikira pamapadi, ng'oma ndi ma disc. Chowonadi ndi chakuti ma calipers ndi ma silinda a brake ali ndi sitiroko ya piston yochepa. Ndipo mapadi ndi masilinda akatha, ma pistoni amayenera kuyenda mopitilira apo kuti apange kulumikizana pakati pa pad ndi disc (drum). Ndipo izi zimafuna madzi ochulukirapo.
Atatulutsa pedal, ma pistoni pang'ono amabwerera pomwe adayambira. Ndipo kuti muwapangitse kuti asunthire mtunda wowonjezereka nthawi yoyamba, ikani kukakamiza pamapepala ndikuwakakamiza motsutsana ndi ng'oma kapena disc ndi mphamvu, kukanikiza pedal yokha sikukwanira. Voliyumu ya master brake silinda sikokwanira kudzaza dongosolo lonse ndikubweretsa kuti lizigwira ntchito. Chopondapo ndi chofewa kuchokera pa makina osindikizira oyambirira. Koma mukaisindikizanso kachiwiri kapena kachitatu, idzakhala yotanuka, ndipo mabuleki azigwira ntchito bwino.
Pachifukwa ichi, ndikofunikira kuyang'ana momwe zinthu zoyendetsera zinthu zilili ndikuzisintha ngati zadziwika.
Komanso nthawi zambiri chomwe chimayambitsa kulephera kwa pedal ndi ma brake pads akumbuyo. Pamagalimoto ambiri palibe njira yodzipangira yokha ikatha. Ndipo mtunda wapakati pa mapepala ndi ng'oma umasinthidwa ndikumangirira zingwe zoyendetsa magalimoto kapena kubweretsa eccentrics. Ndipo mu ufulu waulere, mapepala amabwerera kumalo awo oyambirira ndi kasupe.
Ndipo zikuwonekera kuti mapadi atha, ng'oma nazonso. Mtunda pakati pa zinthuzi umakhala waukulu mosavomerezeka. Ndipo kuti mugonjetse mtunda uwu, mapepala asanagwirizane ndi malo ogwirira ntchito a ng'oma, padzakhala kofunika kupopera madzi ambiri mu dongosolo. Kusindikiza kumodzi kwa brake pedal sikulola kuti izi zichitike. Ndipo pali kumverera kwa idling kwa pedal, kulephera kwake.
Pali njira imodzi yokha yotulukira: kubweretsa mapepala akumbuyo. Pankhaniyi, m'pofunika kuwunika mlingo wa kupanga. Pamitundu ina yamagalimoto, ngozi yotereyi imachitika: mapadi ndi ng'oma zimapangidwa kotero kuti ma pistoni amasilinda amangotuluka kuchokera kukulitsa kwambiri. Ndipo izi zidzapangitsa kulephera kwakuthwa komanso kotheratu kwa ma brake system.
