• huwandu hwemakomba ekukwira ndeye 8.

Brake mashandiro

Iyo braking mechanism ye "manomwe" inomisikidzwa pane yakakosha brake shield, uye iyi nhovo, zvakare, yakachengetedzwa yakachengeteka kune vhiri hub. Hezvino zvinhu zvikuru zveVAZ 2107 brake mechanism:

• mapeji akaputika ane mapedhi akagadzirwa nechinhu chakakosha;
• kaviri-sided brake cylinder (izwi rekuti "maviri-mativi" rinoreva kuti silinda iyi haina imwe, asi mapistoni maviri anotambanudzira kubva kumigumo yakatarisana yechigadzirwa);
• matsime maviri anodzoka;
• hand brake cable;
• hand brake lever.

Mabhureki ekumashure ane chigubhu uye mabhureki.

Iwo maviri mapedhi ari kumashure kwemabhureki anodhonzwa pamwe chete nezvitubu zvekudzoka. Pakati pemapedhi aya pane silinda ine mativi maviri. Kutevedzana kwekushanda kwechigadzirwa chebhureki kunotevera. Mutyairi anorova mabhureki. Uye iyo brake fluid inotanga kukurumidza kuyerera kubva kune huru hydraulic cylinder kuenda kune kaviri-sided silinda mudhiramu. Mapistoni ane mativi maviri anowedzera uye anodzvanya pamapedhi, ayo anotangawo kufamba akaparadzana uye achizorora akatarisana nemadziro emukati edhiramu, achigadzirisa zvakachengeteka mudziyo. Kana mutyairi abvisa motokari kubva pa "handbrake", kumanikidzwa kwebhureki fluid muhurongwa inodonha zvakanyanya, uye pistons ye silinda inoshanda inodzokera zvakare mumuviri wechigadzirwa. Zvitubu zvekudzoka zvinodhonza mapedhi kuti adzokere kunzvimbo yawo yepakutanga, achisunungura dhiramu uye achibvumira vhiri rekumashure kuti ritenderere zvakasununguka.

Ndeipi ngoma

Chigubhu chebhureki chikamu chakakosha, uye zvinodiwa pairi zvakakwirira zvakanyanya. Iyo inonyanya kukosha parameters ndeiyi inotevera:

• dhiramu geometry kururama;
• coefficient of friction yemadziro emukati;
• simba

Imwe yakakosha parameter ndeye zvinhu izvo dhiramu yebhureki inogadzirwa. Ichi chinyorwa chinogona kunge chiri simbi yakakandwa kana aluminium-based alloy. Pa "manomwe", zvichienderana negore rekugadzira muchina, unogona kuwana zvose cast-iron uye aluminium madhiramu.

Madhiramu esimbi emotokari iyi anoonekwa seyakanyanya (pakutanga kuburitswa kweVAZ 2107, yakakandwa madhiramu esimbi). Cast iron ine yakanakisa kusanganisa kwesimba, kuvimbika uye yakakwira coefficient yekukwesha. Pamusoro pezvo, zvigubhu zvesimbi zvakakandwa zvinokwanisika uye zviri nyore kugadzira. Cast iron ine imwe chete yekudzosera kumashure: yakawedzera fragility, iyo yakakosha kana uchityaira mumigwagwa yedu ine makomba.

Kuti agadzirise dambudziko iri, vagadziri veVAZ 2107 vakatora danho rinotevera: vakatanga kuisa madhiramu akagadzirwa nealuminium-based alloys pane gare gare "manomwe" (uyezve, kubva kune alloys - iyi simbi yakanyorova muchimiro chayo chakachena). Uye kuchengetedza huwandu hwepamusoro hwekukweshana kwemadziro emukati, kuiswa-simbi kwakatanga kuiswa mumadhiramu ealuminium. Nekudaro, iyo tekinoroji mhinduro haina kusangana nekunzwisisa pakati pevatyairi. Kusvikira nhasi, varidzi vakawanda ve "manomwe" vanofunga kuti madhiramu e-cast-iron ndiyo yakanakisisa sarudzo, uye kwete alloy.

Zvikonzero uye zviratidzo zvekutadza kwemabhureki kumashure

Iyo VAZ 2107 rear brake mechanism ine chimwe chinhu chisingafadzi: inopisa nyore nyore. Izvi zvinokonzerwa nemagadzirirwo emuchina uyu, uyo usina kufema zvakanaka. Maererano nevagadziri, mabhureki ekumashure e "manomwe" anogona kuvimbiswa kuenda 60 zviuru zvemakiromita pasina kugadziriswa, nepo mabhureki epamberi anogona kungoenda 30 zviuru zvemakiromita. Mukuita, nekuda kwekupisa kuri pamusoro, iyo kumashure brake mileage yakadzikira zvishoma, anenge 50 zviuru zvemakiromita. Mushure meizvozvo, mutyairi anozofanira kutarisana nezviitiko zvinotevera:

• Mapadhi ari mumagetsi ebhureki anopera zvishoma kana zvachose, uye kupfeka kunogona kucherechedzwa kune rimwe divi uye kune ese ari maviri;
  

  Mapedhi ekumashure anopfekwa zvekusvika pasi.
• zvisimbiso mu cylinder yekushanda inoputika nekuda kwekushisa kwepamusoro, semugumisiro wekuti kusungirirwa kwechigadzirwa chacho kwakaputsika, izvo zvinotungamirira pakudonha kwebrake fluid uye kudonha kwakanyanya mukugadzirisa kushanda;
• zvitubu zvekudzoka mumabhureki zvine ngura kwazvo (muzviitiko zvakanyanya zvakanyanya, imwe yadzo inogona kuvhunika, izvo zvinogona kutungamirira kukuputika kwevhiri reshure);
• tambo yehandbrake inopera. Kana tambo yapera, inotambanuka uye inotanga kunyungudika zvakanyanya. Nekuda kweizvozvo, mushure mekuisa mota pa "handbrake", mabhureki mabhureki anoisa zvakanyanya kushoma pamadziro edhiramu, uye mavhiri ekumashure anogadziriswa asina kuvimbika.

Nezvose izvi pfungwa mupfungwa, zvinokurudzirwa zvakasimba kutarisa kumashure kwemabhureki emakiromita zviuru makumi maviri zvemakiromita uye, kana zvichidiwa, ita kudzivirira kwayo. Kunyanya kutarisisa kunofanirwa kubhadharwa kumabhureki ekumashure kana zvinotevera zviratidzo zvekunyevera zvichionekwa:

• kana braking, kudengenyeka kwakasimba kwemotokari kunooneka, iyo mutyairi anonzwa chaizvoizvo nemuviri wake wose;
• mushure mekudzvanya mabhureki, creak yakasimba inoitika, iyo nekufamba kwenguva inogona kushanduka kuita rattle matsi;
• paunenge uchityaira, pane "kurova" kwakasimba kwezvose zviri zviviri chidhiraivho uye brake pedal;
• kushanda kwebhureki kwadzikira zvakanyanya, uye chinhambwe chebhureki chave chakareba.

Zvese izvi zviratidzo zvinoratidza kuti mabhureki anoda kukurumidza kugadziriswa kana kuchengetedzwa kwakanyanya. Hazvibviri zvachose kutyaira nemabhureki akadaro.

dhiramu rakatsemuka

Mitswe idenda chairo remabhureki ese madhiramu, kwete chete pa "manomwe", asiwo pamimwe michina yakawanda ine mabhureki edhiramu. Ruzhinji rwezviratidzo zveyambiro zvakanyorwa pamusoro zvinoonekwa chaizvo mushure mekutsemuka kwengoma. Izvi zvinonyanya kuitika nemadhiramu esimbi. Ichokwadi ndechokuti simbi yakakandwa ndeye alloy yesimbi uye kabhoni, umo kabhoni ine zvinopfuura 2.14%. Carbon inoita simbi yakakandwa kuoma zvisingaite, asi simbi yakakandwa inoita brittle. Kana mutyairi asina kungwarira kutyaira uye achida kuchovha makomba nemhepo, saka kuputika kwengoma dzemabhureki ingori nyaya yenguva.

Kutsemuka mudhiramu nekuda kwekuneta kwesimbi

Chimwe chinokonzeresa kuputika kwengoma kunonzi kuneta kwesimbi. Kana chikamu chikaiswa pasi pe cyclic alternating mitoro kwenguva yakareba, ichiperekedzwa nekuchimbidzika kwekushisa kwekushisa (uye dhiramu rebhureki rinoshanda pasi pemamiriro ezvinhu akadaro), ipapo nekukurumidza kana kuti gare gare kuneta microcrack inooneka muchikamu chakadaro. Hazvibviri kuzviona pasina electron microscope. Pane imwe nguva, mutswe uyu unopararira zvakadzika muchikamu, uye kuparadzira kunoenda nekumhanya kwekunzwika. Somugumisiro, kutsemuka kukuru kunooneka, izvo zvisingabviri kusacherechedza. Ngoma yatsemuka haigadzike. Chekutanga, midziyo yakakosha uye hunyanzvi hunodiwa kuti weld cast iron mugaraji, uye chechipiri, kusimba kwedhiramu rakadaro mushure mekucheka kuchaderedzwa zvakanyanya. Saka muridzi wemota ane sarudzo imwe chete yasara: tsiva chigubhu chebhureki chakatsemuka neitsva.

Pfeka madziro emukati medhiramu

Kupfeka kwemukati madziro edhiramu inzira yechisikigo, mhedzisiro yacho inooneka zvakajeka mushure mekunge mota yapfuura 60 zviuru zvemakiromita zvakaziviswa pamusoro. Sezvo madziro emukati edhiramu achibatwa nguva nenguva nesimba rekukwesha rinogadzirwa nemagetsi ekukwenya pabhutsu dzebhureki, dhayamita yemukati yedhiramu inongowedzera nekufamba kwenguva. Muchiitiko ichi, kushanda kwebhureki kunoderedzwa, nokuti mabheji emakumbo haanyanyi kudzvinyirirwa pamusoro pedhiramu. Mhedzisiro yekupfeka kwechisikigo inobviswa nekugadzirisa dhiramu yebhureki uyezve kugadzirisa mabhureki kuti ive nechokwadi chekukwana kwemapadhi kumadziro emukati.

Grooves pamusoro pepamusoro pedhiramu

Kuonekwa kwema grooves pamusoro pemukati wedhiramu nderimwe dambudziko rinowanzoitika iro varidzi ve "manomwe" vanowanzosangana nazvo. Ichokwadi ndechokuti mabhureki ekumashure pa "manomwe" akagadzirwa nenzira yekuti tsvina nematombo maduku dzimwe nguva anopinda mudhiramu, kunyanya kana mutyairi achityaira zvakanyanya mumigwagwa ine tsvina. Hurungudo imwe kana kupfuura inogona kupera pakati pebhureki shangu nemadziro emukati medhiramu. Kana iyo padhi ichidzvanya hurungudo mukati meiyo dhiramu, inotsikirirwa zvakadzika mukati meiyo friction lining pabhutsu yebhureki uye inoramba iripo (friction lining material yakanyatsopfava). Nekubhureki kwega kwega kunotevera, matombo anonamira mubhuroko anokwenya mukati memadziro edhiramu.

Kukwara kwakakura kunoonekwa pamadziro emukati medhiramu

Nokufamba kwenguva, kukwenya kudiki kunoshanduka kuita muforo mukuru, izvo zvisingazove nyore kubvisa. Nzira yekugadzirisa dambudziko iri inotarirwa nekudzika kwema grooves akaonekwa. Kana mutyairi akazviona kare, uye kudzika kwavo hakupfuuri millimeter imwe, saka unogona kuedza kuvabvisa nekushandura dhiramu. Uye kana kudzika kwema grooves kuri mamirimita maviri kana kupfuura, saka kune nzira imwe chete yekubuda - kutsiva chigubhu chebhureki.

Zvekutsemura mabhureki ngoma

Sezvambotaurwa pamusoro apa, zvimwe zvikanganiso zvakamuka panguva yekushanda kwezvigubhu zvinoputika zvinogona kubviswa uchishandisa iyo inonzi groove. Inofanira kutaurwa pakarepo kuti hazvibviri kukuya chigubhu iwe pachako mugaraji. Nokuti nokuda kweizvi, kutanga, unoda lathe, uye chechipiri, unoda unyanzvi hwekushanda pamushini uyu, uye unyanzvi hwakakomba. Mutyairi wemuchovha haatombozvikudze kuti ane muchina mugaraji rake uye hunyanzvi hunoenderana. Naizvozvo, ane sarudzo imwe chete: kutsvaga rubatsiro kubva kune anokwanisa anotendeuka.

Nokuda kwekutendeuka kwepamusoro kwedhiramu, haugone kuita pasina lathe

Saka chii chinonzi brake drum groove? Kazhinji inoumbwa nematanho matatu:

• gadziriro yegadziriro. Shandura inobvisa inenge hafu yemirimita yesimbi kubva mukati memadziro edhiramu. Mushure maizvozvi, muchina wacho unodzimwa, uye chigubhu chinonyatsoongororwa nokuda kwekukanganisa kwemukati. Nhanho yekugadzirira inokubvumira kuti uone huwandu hwese hwekupfeka kwedhiramu uye kugona kwekuwedzera basa. Dzimwe nguva, mushure megadziriro yekugadzirira, zvinoratidzika kuti groove haina maturo nekuda kwekuremerwa kwehupfeko, uye dhiramu iri nyore kutsiva pane kugaya;
• main stage. Kana, mushure mekutanga kurapwa, zvakazoitika kuti chigubhu chakanga chisina kupera zvakanyanya, ipapo danho guru rekutendeuka rinotanga, panguva iyo mushanduri anonyorovesa uye anokuya zvimedu zviduku uye grooves.
