Mabhureki akaoma kana akapfava. Chii chikonzero uye zvokuita
Iyo braking system chikamu chakakosha che chero mota. Vagadziri vemotokari vanonyatsoteerera mabhureki, vachiziva kuti kuchengeteka mumugwagwa uye hupenyu hwevanhu hunoenderana nebasa ravo rakanaka. Mabhureki emotokari yemazuva ano akavimbika, zvisinei, zvinofanirwa kuyeukwa kuti chero zvikamu panguva yekushanda zvinoiswa pasi pemakanika, kupisa, kemikari uye mamwe marudzi emitoro, uye nekudaro inopera uye inogona kutadza. Zvikamu zvebhureki system hazvisi izvo, chete munyaya iyi mutengo wekuputsika unogona kunge wakanyanya kukwirira.
Zvimwe zviratidzo zvinoonekwa panguva yebhureki zvinogona kunyevera kuti pane chakashata nemabhureki - ruzha rwekunze kana kuzunguzika kwakasimba, mota ichidhonzera parutivi, kusaenzana kana kuderera zvinooneka kuderera kwebhureki uye kuwedzera daro rekubhureki.
Asi chinhu chekutanga chavanowanzo teerera kune maitiro eiyo brake pedal. Inogona kuve yakanyanya kusimba, zvekuti inofanirwa kudzvanywa nechisimba, kana, pane zvinopesana, inogona kungoerekana yave yakapfava, kana kutotadza zvachose. Zvose izvi zvinokanganisa kushandiswa kwebhureki uye zvinogona kutungamirira kumigumisiro yakakomba. Nezve izvo zvinokonzera zviratidzo zvakadaro uye maitiro ekuita mumamiriro ezvinhu akadaro, uye isu tichataura zvakadzama.
Zvinoitika kuti bhureki yakaomesesa pedal stroke inogona kuve yemamwe mamodhi emota. Iyi nuance inoda kujekeswa kana uchangobva kutenga mota kana kuiyedza usati watenga.
Kana zvese zvaive zvakanaka, asi pane imwe nguva wakaona kuti pedal yakangoerekana yave "huni" uye iwe unofanirwa kuisa kumanikidza pairi nekuedza kukuru, saka kazhinji kusashanda kwacho kunoenderana neiyo vacuum brake booster. Ichi chishandiso chakagadzirirwa kuderedza kushanda kwemuviri kunodiwa pakubhureki.
Kureruka kwekutsikirira pedal kunoitika nekuda kwekusiyana kwekumanikidzwa mumhepo uye vacuum makamuri eamplifier. Pakati pemakamuri pane diaphragm ine tsvimbo, iyo inosundira piston ye main brake cylinder (MBC), uye iyo, zvakare, inopomba mumitsara yehurongwa uye mberi kune. Iyo vacuum mukamuri yevacuum inogadzirwa nepombi yemagetsi, uye mune peturu mukati meinjini dzinopisa panobva vacuum kazhinji ndiyo yakawanda yekudyara.
Mumamiriro ekutanga, makamera akabatanidzwa kune mumwe nemumwe. Kana iyo pedal yakatsikirirwa, kamuri yevacuum yakabatanidzwa kune vacuum sosi kuburikidza nevhavha yekutarisa, uye kamuri yemhepo yakabatana nemhepo kuburikidza nevhavha yemhepo. Nekuda kweizvozvo, diaphragm ine tsvimbo inodhonzwa mukamuri yevacuum. Saka, simba rinodiwa kudzvanya paGTZ piston rakaderedzwa. Iyo vacuum amplifier inogona kugadzirwa sechinhu chakasiyana kana kuumba imwechete module neGTZ.
Chinhu chinonyanya kutambudzika pano irabha hose inobatanidza manifold ekutora kune vacuum chamber. Nokudaro, kutanga kwezvose, kuvimbika kwayo kunofanira kuongororwa uye, kana zvichidiwa, kuchinjwa.
Kutyora kwekusimba kunogona kuperekedzwa neasina mwero maitiro einjini yekupisa mukati panguva yebhureki - katatu, kuwedzera kana kuderera kumhanya.Zvinoitika kuti kushandiswa kwemafuta kunowedzera. Izvi zvinokonzerwa nekusvetwa kwemhepo kuburikidza nehosi yakakanganisika uye kupinda kwemusanganiswa wakaonda mukati memagetsi ejini inopisa.
Kana iyo vacuum ichigadzira pombi yevacuum, unofanirwa kuongorora kushanda kwayo.
Mune vacuum booster pachayo, sefa yemhepo inogona kuvharika, diaphragm inogona kukuvara, kana imwe yevhavha inogona kurasikirwa nekufamba kwayo.
Kana zvichidikanwa, unogona kutenga imwe itsva kana kuedza kugadzirisa iripo. Chenjerera paunenge uchiparadzanisa - kune chitubu mukati, pamwe chete nehuwandu hwezvikamu zviri nyore kurasikirwa. Izvo zvinofanirwa kutakurwa mupfungwa kuti kana uchiunganidzazve mushure mekugadzirisa hazvigoneke nguva dzose kuve nechokwadi chekusimba, uye saka zvakajairika kushanda kwechigadzirwa.
Paunenge uchitsiva iyo vacuum booster, hazvidiwi kuparadzanisa iyo GTZ, uye saka, hapana chikonzero chekubuda ropa bhureki system.
Mabhureki anogona zvakare kuoma nekuda kwekuremara mumacuffs muGTZ kana masilinda ekushanda uye, semhedzisiro, kusimba kwepiston mavari. Kurapa ndiko kutsiviwa kwezvikamu zvakakuvadzwa kana masilinda pachawo.
Danho rekutanga nderekuita ongororo yekuona. Ita shuwa kuti hapana mabhureki fluid anodonha uye kuti booster imba haina kukanganisa. ongorora kuvimbika kwehosi uye kusimba kwekubatana kwavo kune zvigadziriso. Simbisa zvisungo kana zvichidiwa.
Kuridza muridzo kunoitika kana brake pedal yakatsikirirwa inogona kuratidza kubuda. Mhere yakadaro inowanzoenderera kwenguva yakati mushure mekunge injini yadzimwa, uye zvino inogona kunzwika zvakajeka.
Pane seti yenzira dzekuongorora mashandiro evacuum amplifier.
Iyo ICE inofanirwa kumiswa. Dzvanya brake pedal 6-7 nguva mumutsara kuti uenzanise kudzvanywa mumakamuri ebooster, wobva wadzvanya mabhureki munzira yese uye wotanga injini munzvimbo iyi. Kana iyo amplifier iri kushanda, vacuum ichaonekwa muhurongwa. Nekuda kwekumanikidzwa kwe membrane, tsinde ichafamba, ichikwevera pusher pamwe chete nayo. Uye sezvo pusher yakabatana nemagetsi kune pedal, inodonha zvishoma, uye iwe unogona kuinzwa zviri nyore netsoka yako. Kana izvi zvikasaitika, saka hapana vacuum muhurongwa. Kana usina chokwadi, edza nzira yechipiri.
Batidza injini, rega iite seti yemaminetsi, wozoidzima. Nyatsodzvinyirira bhureki kaviri kana katatu uye sunungura pedal. Kana iyo vacuum booster iri kushanda nemazvo uye pasina kusveta kwemhepo, ipapo yekutanga kana maviri mashini anozove akapfava, uye anotevera anozove akanyanya kusimba. Kana iwe usingaoni chero mutsauko mukufamba kweiyo pedal, saka kune matambudziko neamplifier.
Neinjini ichimhanya, dzvanya bhureki pedal uye, uchiibata pasi, dzima injini. Kana iwe zvino ukabvisa tsoka yako kubva painotsika, inofanira kuramba iri munzvimbo yakaderedzwa kwechinguva, nekuda kwevacuum yasara mukamuri yekutsvaira yeamplifier.
Kana kudzvanya pedal kwave kupfava zvakanyanya, saka kune mabhuru emhepo mu hydraulics uye ipapo iyo system inofanirwa kubuda ropa, kana kune kurasikirwa kwemvura inoshanda. Danho rekutanga nderekutarisa brake fluid level. Kana iri pazasi peyero inotenderwa, iyo hydraulic system inofanirwa kunyatsoongororwa kuti inodonha. Kutyora kwekusimba kunogoneka pakusangana kwemachubhu ane zvishongedzo nekuda kwezvisungo zvisina kusungwa zvakanaka, uye hose pachayo inogona kukuvara. Mvura inoshanda inogonawo kurasika mumavhiri brake cylinders kana zvisimbiso zvakanganiswa. Mushure mekunge kuvuza kwagadziriswa, zvichave zvakare zvakafanira kubuda ropa hydraulics ye brake system kubvisa mweya kubva mairi.
Kana iyo brake fluid iri yehurombo husina kunaka, yakasvibiswa kana isina kushanduka kwenguva yakareba uye yakarasikirwa nemidziyo yayo, saka kupisa panguva yekukasira mabhureki kunokwanisa kuita kuti ibike, uye ipapo mabhureki anozova "cotton-wool", uye motokari pachayo inenge isina kudzorwa zvakanaka. TJ yekare, yakasviba, kana isingaenderane inogona kukonzera kubatwa kwebrake cylinder, kutadza kuvharika, nemamwe matambudziko. Mhedziso iri pachena - teerera kune mamiriro eiyo brake fluid uye uchinje panguva yakakodzera.
Chimwe chikonzero chekupfava kwebhureki pedal ndiyo hoses, iyo yakagadzirwa nerabha uye inopera nekufamba kwenguva, ichive yakasununguka. Kana hydraulic pressure ichikwira panguva yekubhureki, inongowedzera. Nekuda kweizvozvo, mabhureki anobva anyanya kupfava, uye mabhureki haashande.
Iyo yakanyanyisa uye ine njodzi kuratidzwa kwemabhureki akapfava ndiko kutadza kwepedal. Izvi zvinokonzerwa nekudonha kwakakosha kweTJ kana kukanganisa muO-mhete muGTZ.
Yakanyanya kupfava brake pedal, uye zvakatonyanya kutadza kwayo, inoda mhinduro yekukasira kudambudziko. Unofanira kumira pakarepo, braking injini kana handbrake, uye ipapo kuwana uye kugadzirisa dambudziko.
Mamwe matambudziko ane mabhureki system zvakare anogoneka - kupfeka kana kuisa mafuta, madhisiki nemadhiramu, jamming yemavhiri cylinders uye madhairekitori. Asi chimwe chinhu chakajeka - iyo braking system inoda hunhu hwakakomba. Kugara uchiongorora, kudzivirira uye kutsiva TJ, mhinduro yekukurumidza kumatambudziko uye nenguva yekugadzirisa matambudziko ichakubvumidza kuti unzwe uine chivimbo munzira uye kudzivirira akawanda asingafadzi uye ane njodzi mamiriro ezvinhu.
Shandisa zvigadziriso zvemhando yepamusoro chete, uye kuti usamhanye mune zvenhema, zvitenge kubva kune vanovimbika.
