Brake master silinda inoshanda sei?
Zviri mukati
Iyo hydraulic system yemota mabhureki drive inotanga nemudziyo unofanirwa kushandura simba remakanika riri pamapedali kuita kushanda kwemvura. Iri basa rinoitwa ne hydraulic cylinder, yakatumidzwa zita renzvimbo iyo inogara se "main". Panguva imwecheteyo, vamwe vese havasi vechipiri, vanonzi vashandi kana vakuru.
Chinangwa cheGTZ mumota
Braking inotanga nekutsikirira pedal. Parizvino, haugone kufunga nezvese marudzi ese akangwara ekubatsira mutyairi masisitimu anoita basa rakanaka pasina kutora chikamu kwake.
Iyo yakakura iyo inozotsigira gumbo remunhu anoda kudzikisa mota ndeye vacuum brake booster (VUT), iri pakati pedhizaini musangano uye yekutanga hydraulic mudziyo muketani inopera nemabhureki pads.
Kuita kwekubatana kwesimba remhasuru uye mhepo kuburikidza neWUT membrane inofanira kuwedzera kudzvanywa mune yese hydraulic system. Kana mavharuvhu eABS nemapombi asingapindire, saka kudzvinyirira uku kwakafanana chero nguva.
Zvinwiwa hazvigadzike, ndosaka zvichishandiswa mumabhureki emota. Izvi zvisati zvaitika, zvisizvo zvisingasviki zvisingagadziriswi zvakashandiswa nenzira yematanda uye tambo dzekutyaira mapedhi emichina yekutanga.
Kudzvinyirirwa kwakananga kunogadzirwa chaizvo nepiston yeiyo main brake cylinder (GTZ). Nekuda kwekusagadzikana, inokura nekukurumidza, mutyairi wega wega akanzwa kuti pedal inoomesa sei pasi petsoka mushure mekusarudza kutamba kwayo kwemahara.
Kuburitsa kumanikidza mushure mekuburitsa pedal uye kuzadza mitsara nemvura kana zvichidikanwa mabasa eGTZ.
Ainoita
Single-circuit GTZs, uko kwaingova nepiston imwe chete, haichawanikwi mumotokari, saka chete kaviri-yedunhu inofanira kutariswa. Inosiyaniswa nekuvapo kwepistoni mbiri, imwe neimwe inokonzera kudzvinyirira mubazi rayo rehurongwa.
Saka, mabhureki anodzokororwa, ayo anodiwa kuti achengetedzeke. Kana kubuda kwemvura kukaitika, ipapo bazi rinoramba riri muchimiro chakanaka rinokutendera kuti umise mota pasina kushandisa bhureki rekupaka uye mamwe maitiro ekukurumidzira.
Piston yekutanga yakabatana zvakananga kune pedal stem. Kutanga kuenda kumberi, inovhara maburi ekupfuura uye maburi, mushure mezvo simba kuburikidza nevhoriyamu yemvura rinobva raendeswa kumapadhi edunhu rekutanga. Ivo vanozodzvanya kurwisa madhisiki kana zvigubhu, uye deceleration ichatanga nerubatsiro rwekukwesha masimba.
Kudyidzana nepiston yechipiri kunoitwa kuburikidza netsvimbo pfupi ine chitubu chekudzoka uye yekutanga dunhu remvura. Ndiko kuti, pistons akabatanidzwa munhevedzano, saka maGTZ akadaro anonzi tandem. Iyo piston yedunhu rechipiri inoshanda zvakafanana nebazi rayo rehurongwa.
Kazhinji, masilinda evhiri anoshanda diagonally, ndiko kuti, rimwe kumberi uye rimwe rekumashure vhiri rakabatana kune rimwe nerimwe redunhu. Izvi zvinoitwa nechinangwa chekuti chero ipi zvayo ishandise kumberi, kwakanyanya kushanda mabhureki, zvishoma zvishoma.
Asi kune motokari umo, nokuda kwezvikonzero zvekugadzirisa, rimwe dunhu rinoshanda chete pamavhiri epamberi, uye yechipiri pamakumbo mana, ayo anoshandiswa mamwe seti emagumbo.
Device
Iyo GTC inosanganisira:
- imba ine zvigadziriso zvinopa mvura kubva kune tangi yekugovera uye kudonhedza kune mitsetse yemasilinda anoshanda;
- pistons yekutanga neyechipiri matunhu;
- kuvhara rubber cuffs iri mumigero yepiston;
- dzoka zvitubu zvinomanikidza kana pistons kufamba;
- anther inovhara nzvimbo yekupinda yetsvimbo kubva kuVUT kana pedal ichipinda mumashure ekuseri kwepiston yekutanga;
- screw plug inovhara humburumbira kubva kumagumo, nekusunungura iyo yaunogona kuunganidza kana kupatsanura silinda.
Makomba ekubhadhara ari muchikamu chepamusoro chemuviri wecylinder, anogona kupindirana kana mapistoni achifamba, achiparadzanisa iyo yakakwira yekumanikidza mhango uye tangi rekupa nekupihwa kwemvura.
Iyo tangi pachayo inowanzobatanidzwa yakananga kune silinda kuburikidza nekuvhara cuffs, kunyangwe inogona kutamirwa kune imwe nzvimbo mukamuri yeinjini, uye kubatana kunoitwa kuburikidza neakaderera mahosi ekumanikidza.
Kukanganisa kukuru
Kuputsika mune master brake cylinder haatomboverengerwa, uye zvese zvinokanganisa zvinosanganiswa nekupfuura kwemvura kuburikidza nezvisimbiso:
- kupfeka uye kuchembera kwechisimbiso makora padivi retsvimbo, iyo mvura inopinda mugomba revacuum booster kana, kana isipo, mukamuri yevafambi, kutsoka dzemutyairi;
- Kutyorwa kwakafanana kwemacuffs pamapistoni, silinda inotanga kupfuura imwe yemasekete, pedal inotadza, braking inowedzera;
- kuroora kwepiston nekuda kwekuora kwavo pachavo uye cylinder girazi, pamwe nekurasikirwa kwekusimba kwezvitubu zvekudzoka;
- kuwedzera kwekurohwa uye kuderera kwepedal stiffness panguva yekuputika nekuda kwemhepo mumutsara webhureki.
Kune dzimwe mota, makiti ekugadzirisa ane pistons uye cuffs achiri kuchengetedzwa mune zvakasara zvikamu makatalogi. Zvakare kurudziro yekubvisa humburumbira pamusoro pezvikanganiso nesandpaper.
Mukuita, basa iri harina kunyatsonzwisisa, hazvigoneke kuti zvikwanise kuwedzera zvakanyanya sosi yeGTZ yakashanda, uye kutyaira neasina kuvimbika brake hydraulic cylinder, iyo isiri pasina iyo inonzi iyo huru. , hazvifadzi uye zvine ngozi. Nokudaro, muhuwandu hwakawanda hwezviitiko, silinda inotsiviwa negungano idzva.
Maitiro ekutarisa uye kubuda ropa brake master silinda
GTZ inotariswa zviratidzo zvedambudziko nemabhureki. Kazhinji uku kutadza kana kupfava pedal ine kuwedzera kwekufamba. Kana cheki yemasilinda ose anoshanda uye hoses isingaratidzi zviratidzo zvekusashanda, zvino inopedzwa mune iyo huru, iyo inofanirwa kutsiviwa.
Unogona kufungidzira kuita nekusunungura pombi dzemabhureki kubva paGTZ imwe neimwe uye nekuona kusimba kwekudonha kana uchidzvanya pedal. Asi hapana chakakosha chinodiwa cheizvi, GTZ yakashanda inotsiviwa nekufungira kudiki, kuchengetedza kunodhura.
Paunenge uchitsiva silinda, inozadzwa nemvura yakachena, uye mweya wakawandisa unopinda mutangi kuburikidza nemakomba ekupfuura, saka hapana chakakosha chekupomba kwakasiyana. Zvakakwana kuramba uchitsikirira pedal ne general pumping yegadziriro kuburikidza nemavharuvhu emaitiro ekushanda.
Kana, nokuda kwechimwe chikonzero, zvakakodzerawo kupomba GTZ, saka nokuda kweizvi, kushanda pamwe chete, zvigadzirwa zvinobuda zvakavharwa zvakatevedzana, kunze kweimwe. Mhepo inobuda mairi nekuivhura usati wadzvanya pedal nekuivhara usati wairegedza.
Hapana chikonzero chekubvisa machubhu, zvakakwana kuti "udzikise" iwo nekusunungura zvishoma nut yemubatanidzwa. Muchiitiko ichi, zvakakosha kutarisa huwandu hwakakwana hwemvura mutangi.
Kuchengetedzeka kwecylinder uye kuve nechokwadi chehupenyu hwayo hurefu hwesevhisi inovimbiswa nekutsiviwa kwakarongwa kweiyo brake fluid nekutsvaira sisitimu. Nokufamba kwenguva, mvura inosvika ikoko, inotorwa nehygroscopic yakagadzirwa kubva kumhepo.
Nekuda kweizvozvo, kwete chete iyo yekubikira inodonha, iyo ine njodzi, asi ngura yepasi pepiston nemasilinda kunotanga, uye cuffs inorasikirwa nekusimba kwayo. Iyo nzira inokurudzirwa kuti iitwe makore maviri ega ega.
