Silinda Master-ka (Master Sylinder), oo sidoo kale loo yaqaanno saliidda ugu weyn (hawada), shaqadiisa ugu weyni waa inay riixdo dareeraha biriiga (ama gaaska) si loogu gudbiyo dhululubo kasta oo biriiga si ay u riixdo bistanka.
Silinda barreegga Master-ka waa hal-jid u dhaqma piston hydraulic cylinder, shaqadeeduna waa in tamarta makaanikada loo beddelo habka baallaha oo u beddelo tamar hawooreed.Waxaa jira laba nooc oo ah dhululubada master-ka ee biriiga, hal-qol iyo laba-qol, kuwaas oo loo adeegsado nidaamyada hal-wareeg iyo laba-wareeg ah ee nidaamka braking hydraulic.
Si loo hagaajiyo badbaadada wadista baabuurta, iyadoo la raacayo shuruudaha xeerarka taraafiggu, nidaamka bareegga adeegga ee baabuurtu hadda wuxuu qaadanayaa nidaamka bareegga laba-wareegga ah, kaas oo ka kooban silsilado laba-qol ah oo taxane ah (brake hal qol ah). dhululubada master-ka ayaa la tirtiray).nidaamka braking hydraulic dual-circuit.
Waqtigan xaadirka ah, ku dhawaad dhammaan nidaamyada bareegga biyo-xidheenka ee laba-wareegga ah waa nidaamyada bareegga ee servo ama nidaamyada braking firfircoon.Si kastaba ha ahaatee, qaar ka mid ah baabuurta yar yar ama kuwa fudud, si qaab-dhismeedku u fududaado, iyo shuruudda in xoogga bireega ahi aanu dhaafin xadka awoodda jireed ee darawalka, waxaa sidoo kale jira qaar ka mid ah moodooyinka isticmaala bareeg laba-qol ah oo tandem ah. mastar dhululubo si uu u sameeyo bireega biyo-xidheenka ah ee gacanta laba-wareeg ah.nidaamka.
Tandem laba-qol bareega dhisme dhululubo
Noocan ah dhululubada bareegga waxaa lagu isticmaalaa nidaamka bireega hayrooliga ah ee laba-wareeg ah, kaas oo u dhigma laba silsiladood oo bireega ah ee hal qol ah oo taxane ah.
Guryaha bireega Master cylinder waxay ku qalabaysan yihiin piston cylinder 7, piston cylinder 12, guga cylinder hore 21 iyo guga cylinder gadaal 18.
Biistoonka dhululubada hore waxa lagu xidhay giraanta wax lagu xidho 19;bisinka dhululubada danbe waxa lagu shaabadeeyey giraanta xidhidhiyaha 16, waxana la dhigay giraanta xajinta 13. Labada kayd ee dareeraha ah siday u kala horreeyaan waxa lala xidhiidhaa qolka hore ee B iyo qolka danbe A, waxaana lala xidhiidhiyaa dhululubada giraangiraha hore iyo danbe 3. Biistoonka hore ee dhululubada waxaa riixaya xoogga biyaha ee bisinka dhululubada gadaale, piston dhululubada danbe waxaa si toos ah u dhaqaajinaya usha riixitaanka.15 riix
Marka dhululubada bareeggu aanu shaqaynayn, madaxa bistoonka iyo koobka ku yaal qolalka hore iyo gadaalba waxay ku yaalaan inta u dhaxaysa godadka dhaafka 10 iyo godadka magdhowga 11 .Awoodda laastikada ah ee guga soo noqoshada ee piston ee dhululubada hore waxay ka weyn tahay guga soo noqoshada ee piston ee dhululubada danbe si loo hubiyo in labada piston ay ku jiraan booska saxda ah marka aysan shaqaynayn.
Marka biriiga la qabanayo, dareewalku wuxuu ku tallaabsanayaa baydka bireega, xoogga baydalka waxaa loo gudbiyaa usha riixitaanka 15 iyada oo loo marayo habka gudbinta, oo riixaya piston cylinder 12 si uu horay ugu socdo.Ka dib markii koobka maqaarku uu daboolo godka la dhaafo, cadaadiska godka danbe ayaa kordha.Marka la eego ficilka cadaadiska hydraulic ee qolka dambe iyo xoogga guga ee dhululubada dambe, piston 7 ee dhululubada hore ayaa horay u socota, cadaadiska qolka hore ayaa sidoo kale kor u kacaya.Marka baydka biriiga uu sii wado in hoos loo sii cadaadiyo, cadaadiska hydraulic ee qolalka hore iyo dambe ayaa sii kordhaya, taas oo ka dhigaysa bareegyada hore iyo dambe.
Marka biriiga la sii daayo, darawalku waxa uu sii daayaa badhka biriiga, iyada oo ay fulinayaan ilaha hore iyo kan dambe ee biistoonka, piston-ka iyo usha riixaya ee dhululubada bareeggu waxa ay ku soo noqonayaan booskii hore, saliidii dhuumaha ayaa riixaysa saliidda soo celi waalka 22 oo dib u soo noqda Silinda sayidku waa la jabiyay, si ay saamaynta barkinku u baaba'do.
Haddii wareegga ay gacanta ku hayso qolka hore uu ku guuldareysto, piston dhululubada hore ma dhaliso cadaadis biyo ah, laakiin iyadoo la raacayo xoogga biyaha ee piston dhululubada dambe, piston dhululubada hore ayaa lagu riixaa dhinaca hore, iyo cadaadiska haydarooliga ka dib Qolka ayaa weli ka dhigi kara taayirrada danbe inay soo saaraan xoog bareegga.Haddii wareegga ay gacanta ku hayso qolka dambe uu guuldareysto, qolka dambe ma dhalinayo cadaadis biyo ah, laakiin piston-ka dhululubada dambe ayaa horay u socdaa iyada oo la raacayo ficilka usha riixitaanka, oo la xidhiidha piston-ka hore ee dhululubada si uu hore ugu riixo piston cylinder hore, iyo Qolka hore ayaa wali dhalin kara bareegaha cadaadiska Haydarooliga ee taayirrada hore.Waxaa la arki karaa in marka nooc kasta oo dhuumo ah oo ku jira nidaamka bireega haydarooliga ee dual-circuit ay fashilmaan, dhululubada master-ka ee biriiga uu wali shaqayn karo, laakiin istaroogga pedal ee loo baahan yahay waa la kordhiyaa.
