Kodi silinda ya brake master imagwira ntchito bwanji?

Dongosolo la hydraulic la ma brake drive agalimoto limayamba ndi chipangizo chomwe chimayenera kusinthira mphamvu yamakina pama pedals kukhala kuthamanga kwamadzimadzi. Ntchitoyi imaseweredwa ndi silinda ya hydraulic, yomwe imatchedwa malo omwe amakhala ngati "main". Panthawi imodzimodziyo, ena onse sali achiwiri, amatchedwa antchito kapena akuluakulu.

Cholinga cha GTZ m'galimoto

Mabuleki amayamba ndi kukanikiza pedal. Pakadali pano, simungaganizire mitundu yonse yamakina othandizira oyendetsa omwe amachita bwino kwambiri popanda kutenga nawo gawo.

Kuchuluka komwe kungathandize mwendo wa munthu amene akufuna kuchepetsa galimotoyo ndi vacuum brake booster (VUT) yomwe ili pakati pa msonkhano wa pedal ndi chipangizo choyamba cha hydraulic mu unyolo womwe umatha ndi ma brake pads.

Kuphatikizika kwa mphamvu ya minofu ndi mlengalenga kudzera mu nembanemba ya WUT ziyenera kuonjezera kupanikizika mu dongosolo lonse la hydraulic. Ngati ma valve a ABS ndi mapampu salowererapo, ndiye kuti kuthamanga uku kumakhala kofanana nthawi iliyonse.

Zamadzimadzi ndizosasunthika, chifukwa chake zimagwiritsidwa ntchito pamabuleki agalimoto. Izi zisanachitike, zolimba zosachepera zosasunthika zidagwiritsidwa ntchito ngati ndodo ndi zingwe zoyendetsa mapepala amakina oyamba.

Kuthamanga kwachindunji kumapangidwa ndendende ndi pisitoni ya silinda yayikulu ya brake (GTZ). Chifukwa chosasunthika, imakula mofulumira kwambiri, dalaivala aliyense amamva momwe pedal imaumitsa pansi pa phazi atasankha kusewera kwake kwaulere.

Kutulutsa kuthamanga mutatha kutulutsa pedal ndikuwonjezera mizere ndi madzi ngati kuli kofunikira ndi ntchito za GTZ.

Momwe ntchito

Single-circuit GTZs, kumene kunali pisitoni imodzi yokha, sapezekanso m'magalimoto, kotero kuti ndi imodzi yokha yozungulira yomwe iyenera kuganiziridwa. Zimasiyanitsidwa ndi kukhalapo kwa ma pistoni awiri, omwe ali ndi udindo wokakamiza munthambi yake ya dongosolo.

Chifukwa chake, mabuleki amapangidwanso, zomwe zimafunikira kuti zitetezeke. Ngati kutayikira kwamadzimadzi kumachitika, ndiye kuti nthambi yomwe imakhalabe yabwino imakulolani kuyimitsa galimoto popanda kugwiritsa ntchito mabuleki oimika magalimoto ndi njira zina zadzidzidzi.

Pistoni yoyamba imalumikizidwa mwachindunji ndi tsinde la pedal. Kuyamba kupita patsogolo, kumatseka malire ndi mabowo a chipukuta misozi, kenako mphamvu kudzera mu voliyumu yamadzimadzi idzasamutsidwa nthawi yomweyo ku mapepala a dera loyamba. Adzakanikiza ma diski kapena ng'oma, ndipo deceleration idzayamba mothandizidwa ndi mphamvu zotsutsana.

Kuyanjana ndi pisitoni yachiwiri kumapangidwa kudzera mu ndodo yaifupi yokhala ndi kasupe wobwerera ndi madzimadzi ozungulira. Ndiko kuti, pisitoni olumikizidwa mu mndandanda, choncho GTZs amatchedwa tandem. Pistoni ya dera lachiwiri imagwira ntchito mofanana ndi nthambi yake ya dongosolo.

Nthawi zambiri, ma silinda ogwirira ntchito amagwira ntchito diagonally, ndiye kuti, kutsogolo ndi kumbuyo kumalumikizidwa kudera lililonse. Izi zachitika ndi cholinga Mulimonse ntchito kutsogolo, kothandiza mabuleki, osachepera pang'ono.

Koma pali magalimoto omwe, chifukwa cha zomangamanga, dera limodzi limagwira ntchito pamawilo akutsogolo okha, ndipo lachiwiri pazinayi zomwe zimagwiritsidwa ntchito popanga zida zowonjezera.

chipangizo

GTC ikuphatikizapo:

• nyumba yokhala ndi zopangira zoperekera madzi kuchokera ku tanki yoperekera ndikukhetsa ku mizere ya masilinda ogwirira ntchito;
• ma pistoni a mabwalo oyamba ndi achiwiri;
• kusindikiza ma cuffs a mphira omwe ali m'mizere ya pistoni;
• kubweza akasupe amene compress pamene pistoni kusuntha;
• anther yophimba malo olowera ndodo kuchokera ku VUT kapena pedal kulowa kumbuyo kwa pisitoni yoyamba;
• pulagi yotsekera yomwe imatseka silinda kuchokera kumapeto, mwa kumasula zomwe mungathe kusonkhanitsa kapena kusokoneza silinda.

Mabowo amalipiro amakhala kumtunda kwa thupi la silinda, amatha kuphatikizika pamene ma pistoni amasuntha, kulekanitsa mphuno yothamanga kwambiri ndi thanki yoperekera ndi madzimadzi.

Silinda yokhayo nthawi zambiri imamangiriridwa mwachindunji ku silinda kudzera m'makona osindikizira, ngakhale imatha kusamutsidwa kupita kumalo ena m'chipinda cha injini, ndipo kugwirizanako kumapangidwa ndi ma hoses otsika kwambiri.

Zovuta zazikulu

Kuwonongeka kwa silinda ya master brake sikuphatikizidwa, ndipo zovuta zonse zimalumikizidwa ndi kutuluka kwamadzimadzi kudzera mu zisindikizo:

• kuvala ndi kukalamba kwa makola osindikizira kumbali ya ndodo, madziwo amapita kumtunda wa vacuum booster kapena, ngati palibe, kulowa m'chipinda chokwera, kumapazi a dalaivala;
• kuphwanya kofananira kwa ma cuffs pa pistoni, silinda imayamba kudutsa imodzi mwamabwalo, chopondapo chimalephera, kuphulika kumakulirakulira;
• kugwetsa ma pistoni chifukwa cha dzimbiri lawo okha ndi galasi yamphamvu, komanso kutayika kwa elasticity kwa akasupe obwerera;
• kuwonjezeka kwa sitiroko ndi kuchepa kwa kuuma kwa pedal panthawi ya braking chifukwa cha mpweya mu mzere wa brake.

Kwa magalimoto ena, zida zokonzera zokhala ndi ma pistoni ndi ma cuffs zimasungidwabe m'makatalogu a zida zosinthira. Komanso malingaliro ochotsa zolakwika za silinda pamwamba ndi sandpaper.

M'zochita, ntchito imeneyi si nzeru kwambiri, n'zokayikitsa kuti n'zotheka kukulitsa kwambiri gwero la GTZ ntchito, ndi kuyendetsa ndi wosadalirika ananyema yamphamvu hayidiroliki, amene si pachabe amatchedwa waukulu. , ndi zosasangalatsa komanso zowopsa. Choncho, nthawi zambiri, silinda imasinthidwa ndi msonkhano watsopano.

Momwe mungayang'anire ndi kukhetsa magazi silinda ya master brake

GTZ imayang'aniridwa ngati pali vuto ndi mabuleki. Nthawi zambiri izi zimakhala zolephereka kapena zofewa zokhala ndi maulendo ochulukirapo. Ngati cheke cha masilindala onse ogwira ntchito ndi ma hoses sakuwonetsa kulephera, ndiye kuti chimatsirizika m'magawo akulu, omwe ayenera kusinthidwa.

Mutha kuyerekeza momwe ntchitoyo ikugwirira ntchito pomasula zoyimbira za ma brake kuchokera ku GTZ kenako ndikuwona kuchucha kwamphamvu mukamakanikizira chopondapo. Koma palibe chofunika kwambiri pa izi, GTZ yomwe yagwira ntchito imasinthidwa ndi kukayikira pang'ono, chitetezo ndi chokwera mtengo.

Mukasintha silinda, imadzazidwa ndi madzi atsopano, ndipo mpweya wochuluka umalowa mu thanki kudzera m'mabowo odutsa, kotero palibe chofunikira chapadera cha kupopera kosiyana. Ndikokwanira kukanikiza mobwerezabwereza pedal ndi kupopera kwakukulu kwa dongosolo kudzera mu mavavu a njira zogwirira ntchito.

Ngati, pazifukwa zina, ndi kofunika kupopera GTZ, ndiye chifukwa ichi, ntchito pamodzi, zovekera linanena bungwe motsatizana oletsedwa, kupatula mmodzi. Mpweya umatulukamo potsegula musanakanikize chopondapo ndi kutseka musanachitulutse.

Palibenso chifukwa chodula machubu, ndikokwanira "kuwafooketsa" mwa kumasula pang'ono mtedza wa mgwirizano. Pankhaniyi, m`pofunika kuwunika okwanira kuchuluka kwa madzi mu thanki.

Momwe mungatulutsire magazi a BRAKE MASTER CYLINDER

Chitetezo cha silinda ndikuwonetsetsa kuti moyo wake wautali wautumiki umatsimikiziridwa ndikusintha kwanthawi yake kwa brake fluid ndikutsuka makinawo. M'kupita kwa nthawi, madzi amafika kumeneko, kutengedwa ndi hygroscopic kapangidwe ka mlengalenga.

Chotsatira chake, sikuti malo otentha amatsika okha, omwe ndi owopsa, koma dzimbiri za malo a pistoni ndi masilindala zimayamba, ndipo ma cuffs amataya mphamvu zawo. Ndondomeko tikulimbikitsidwa kuti ichitike zaka ziwiri zilizonse.
