I-master cylinder (Master Cylinder), ekwabizwa ngokuba yi-oyile yebrake main (umoya), owona msebenzi wayo kukutyhala i-brake fluid (okanye igesi) ukuze idluliselwe kwi-cylinder ye-brake nganye ukutyhala ipiston.
Ibrake master cylinder yindlela enye esebenza ngayo ipiston hydraulic cylinder, kwaye umsebenzi wayo kukuguqula igalelo lamandla ngoomatshini ngendlela enyovwayo ibe ngamandla oxinzelelo. Kukho iindidi ezimbini zeesilinda ze-brake master, igumbi elinye kunye negumbi elimbini, ezisetyenziswa ngokulandelelana kwiinkqubo zokuqhobosha ze-hydraulic zesekethe enye.
Ukuze kuphuculwe ukhuseleko lokuqhuba kweemoto, ngokweemfuno zemithetho yendlela, inkqubo yokuqhoboshwa kwenkonzo yemoto ngoku yamkela inkqubo yokuqhoboshwa kwee-double-circuit, equlunqwe luthotho lwe-dual-chamber master cylinders (ibhuleki enegumbi elinye. ii-master cylinders ziye zacinywa). inkqubo yokuqhoboshwa kwe-hydraulic braking yesekethe ezimbini.
Okwangoku, phantse zonke iisistim zokuqhoboshwa kwe-hydraulic hydraulic braking systems zii-servo braking systems okanye ii-dynamic braking systems. Nangona kunjalo, kwezinye iimoto ezincinci okanye ezilula, ukwenza ulwakhiwo lube lula, kwaye phantsi kwemeko yokuba amandla e-brake pedal ayidluli kuluhlu lwamandla omzimba womqhubi, zikwakho ezinye iimodeli ezisebenzisa i-tandem-dual-chamber brake. master cylinder ukwenza i-dual-circuit manual hydraulic brake. inkqubo.
I-Tandem ye-double-chamber brake master cylinder isakhiwo
Olu hlobo lwe-cylinder master brake lusetyenziswa kwi-dual-circuit hydraulic brake system, elingana neesilinda ezimbini ze-brake master cylinders ezidityaniswe kuthotho.
Izindlu zebrake master cylinder zixhotyiswe ngepiston yesilinda 7 yangaphambili, ipiston yangasemva eyi-12, isilinda sangaphambili se-21 kunye ne-cylinder engasemva yasentwasahlobo 18.
I-piston ye-cylinder yangaphambili itywinwe ngomsesane wokutywina we-19; i-cylinder piston yangasemva itywinwe ngomsesane wokutywina 16, kwaye ibekwe ngendandatho yogcino 13. Amachibi amabini angamalwelo ngokulandelelana anxibelelana negumbi langaphambili B kunye negumbi elingasemva A, kwaye zinxibelelene nomphambili kunye neesilinda zamavili zokuqhafaza ngasemva. ngeevalvu zokuphuma kweoyile ngokwahlukeneyo 3. Ipiston yesilinda yangaphambili ityhalwa ngamandla olwelo olwenziwa ngamanzi. ipiston yesilinda yangasemva, kunye nepiston yesilinda yangasemva iqhutywa ngokuthe ngqo ngentonga yokutyhala. 15 tyhala.
Xa i-cylinder ye-brake master ingasebenzi, intloko yepiston kunye nekomityi kumagumbi angaphambili nangasemva abekwe nje phakathi kwemingxunya ye-bypass eyi-10 kunye nemingxuma yembuyekezo ye-11. I-elastic force ye-return spring ye-piston ye-cylinder yangaphambili inkulu kunaleyo ye-spring spring ye-piston ye-cylinder yangasemva ukuqinisekisa ukuba iipiston ezimbini zikwindawo echanekileyo xa zingasebenzi.
Xa uqhuba isiqhoboshi, unyathela kwi-pedal ye-brake, i-pedal force igqithiselwa kwi-push rod 15 nge-transmission mechanism, kwaye ityhala i-cylinder piston 12 yangasemva ukuya phambili. Emva kokuba indebe yesikhumba igubungele umngxuma we-bypass, uxinzelelo kwi-cavity yangasemva luyanda. Ngaphantsi kwesenzo soxinzelelo lwe-hydraulic kwigumbi elingasemva kunye ne-spring force ye-cylinder yangasemva, i-piston 7 ye-cylinder yangaphambili iqhubela phambili, kwaye uxinzelelo olukwigumbi langaphambili luyanda. Xa i-pedal ye-brake iqhubeka nokuxinzelelwa phantsi, uxinzelelo lwe-hydraulic kumagumbi angaphambili kunye namagumbi angasemva aqhubekile ukunyuka, okwenza i-brakes yangaphambili kunye ne-back brakes.
Xa ibrake ikhululiwe, umqhubi ukhulula i-pedal ye-brake, phantsi kwentshukumo yangaphambili nasemva kwemithombo yepiston, ipiston kunye nentonga yokutyhala kwi-brake master cylinder ibuyela kwindawo yokuqala, kwaye i-oyile ekumbhobho ityhala ivule ioyile. ivalve yokubuyisela i-22 kwaye ibuyela umva I-master cylinder ibhulekiwe, ukuze isiphumo sokuqhawula sinyamalale.
Ukuba isekethe elawulwa ligumbi langaphambili iyasilela, i-cylinder piston yangaphambili ayivelisi uxinzelelo lwehydraulic, kodwa phantsi kwamandla oxinzelelo lwe-hydraulic yepiston yesilinda yangasemva, ipiston yecylinder yangaphambili ityhalelwa ngaphambili, kunye noxinzelelo lwehydraulic oluveliswa ngasemva. igumbi usenokwenza ivili langasemva ukuvelisa amandla okuqhobosha. Ukuba isekethe elawulwa ligumbi elingasemva ayiphumeleli, igumbi elingasemva alivelisi uxinzelelo lwehydraulic, kodwa i-cylinder piston yangasemva iqhubela phambili phantsi kwentonga yokutyhala, kwaye inxibelelana nepiston yesilinda yangaphambili ukutyhala ipiston ngaphambili, kwaye Igumbi langaphambili lisenokuvelisa iziqhoboshi zoxinzelelo lweHydraulic kumavili angaphambili. Inokubonwa ukuba xa nayiphi na isethi yemibhobho kwinkqubo yebrake ye-hydraulic brake system isilela, isilinda esilawula ibrake isengasebenza, kodwa i-pedal stroke efunekayo iye yonyuka.
