Master Cylinder (Master Cylinder), yomwe imadziwikanso kuti brake main oil (mpweya), ntchito yake yayikulu ndikukankha brake fluid (kapena gasi) kuti iperekedwe ku silinda ya brake iliyonse kukankhira pisitoni.
Brake master cylinder ndi njira imodzi yochitira piston hydraulic cylinder, ndipo ntchito yake ndikusinthira mphamvu yamakina ndi makina onyamulira kukhala mphamvu yama hydraulic. Pali mitundu iwiri ya ma silinda ambuye a brake master, chipinda chimodzi ndi chipinda chapawiri, chomwe chimagwiritsidwa ntchito motsatana limodzi ndi ma hydraulic braking system.
Kuti apititse patsogolo chitetezo chamagalimoto, molingana ndi zofunikira zamagalimoto, makina oyendetsa magalimoto oyendetsa magalimoto tsopano akutenga ma braking amtundu wapawiri, omwe amapangidwa ndi masilindala a master-chamber master cylinders (silinda yama brake master silinda yachotsedwa). wapawiri-circuit hydraulic braking system.
Pakali pano, pafupifupi ma 2-circuit hydraulic braking systems ndi ma servo braking systems kapena dynamic braking systems. Komabe, m'magalimoto ena ang'onoang'ono kapena opepuka, kuti mawonekedwewo akhale osavuta, komanso ngati mphamvu yoyendetsa ma brake sidutsa kuchuluka kwa mphamvu zakuthupi za dalaivala, palinso mitundu ina yomwe imagwiritsa ntchito silinda ya tandem ya dual-chamber brake master cylinder kuti ipange mabuleki apawiri-circuit manual hydraulic brake. dongosolo.
Tandem double-chamber brake master cylinder structure
Silinda yamtundu uwu wa brake master cylinder imagwiritsidwa ntchito pawiri-circuit hydraulic brake system, yomwe ili yofanana ndi ma silinda a master wachipinda chimodzi olumikizidwa motsatizana.
Nyumba ya silinda ya brake master ili ndi pistoni yakutsogolo 7, pistoni yakumbuyo 12, silinda yakutsogolo 21 ndi silinda yakumbuyo kasupe 18.
Pistoni ya silinda yakutsogolo imasindikizidwa ndi mphete yosindikiza 19; pisitoni yam'mbuyo ya silinda imasindikizidwa ndi mphete yosindikiza 16, ndipo imayikidwa ndi mphete yosungira 13. Zosungiramo ziwiri zamadzimadzi zimagwirizanitsidwa ndi chipinda chakutsogolo B ndi chipinda cham'mbuyo A, ndipo amalankhulana ndi ma cylinders kutsogolo ndi kumbuyo kwa magudumu amtundu wawo kupyolera muzitsulo zawo zamtundu wa hydraulic cylinder 3. pisitoni ya silinda yakumbuyo, ndipo pisitoni ya silinda yakumbuyo imayendetsedwa mwachindunji ndi ndodo yokankha. 15 kukankha.
Pamene silinda ya brake master sikugwira ntchito, mutu wa pistoni ndi chikho kutsogolo ndi zipinda zam'mbuyo zimangokhala pakati pa mabowo 10 ndi mabowo 11. Mphamvu zotanuka za kasupe wobwerera wa pisitoni ya silinda yakutsogolo ndi yayikulu kuposa ya kasupe wobwerera wa pisitoni ya silinda yakumbuyo kuti zitsimikizire kuti ma pistoni awiriwo ali pamalo oyenera pomwe sakugwira ntchito.
Akamakwera mabuleki, dalaivala amaponda pa brake pedal, mphamvu yopondayo imatumizidwa ku kankhira ndodo 15 kudzera mu makina otumizira, ndikukankhira pistoni yakumbuyo 12 kuti apite patsogolo. Kapu yachikopa ikaphimba dzenje lodutsa, kukakamiza kumbuyo kumawonjezeka. Pansi pa mphamvu ya hydraulic m'chipinda cham'mbuyo ndi mphamvu yamasika ya silinda yakumbuyo, pisitoni 7 ya silinda yakutsogolo ikupita patsogolo, ndipo kupanikizika kuchipinda chakutsogolo kumawonjezeka. Pamene ma brake pedal akupitiriza kukanikizidwa pansi, kuthamanga kwa hydraulic kutsogolo ndi zipinda zam'mbuyo kumapitirira kuwonjezeka, kupangitsa mabuleki akutsogolo ndi akumbuyo.
Pamene brake imatulutsidwa, dalaivala amamasula chopondapo, pansi pa pisitoni yakutsogolo ndi yakumbuyo, pisitoni ndi ndodo yokankhira mu silinda ya brake master zimabwerera pamalo oyamba, ndipo mafuta omwe ali mupaipi amakankhira valavu yobwezeretsa mafuta 22 ndikubwerera mmbuyo Silinda yambuyeyo imaphwanyidwa, kotero kuti braking imasowa.
Ngati dera loyang'aniridwa ndi chipinda chakutsogolo likulephera, pisitoni ya silinda yakutsogolo sipanga mphamvu ya hydraulic, koma pansi pa mphamvu ya hydraulic ya pistoni yakumbuyo ya silinda, pisitoni yakutsogolo imakankhidwira kutsogolo, ndipo kuthamanga kwa hydraulic kopangidwa ndi chipinda chakumbuyo kumatha kupangitsa kuti gudumu lakumbuyo lipange braking mphamvu. Ngati dera loyang'aniridwa ndi chipinda chakumbuyo likulephera, chipinda chakumbuyo sichimapanga kuthamanga kwa hydraulic, koma pisitoni ya cylinder yakumbuyo imasunthira kutsogolo pansi pa ndodo yokankhira, ndikulumikizana ndi pisitoni yakutsogolo kukankhira pisitoni yakutsogolo, ndipo chipinda chakutsogolo chikhoza kupangabe mabuleki a Hydraulic pressure mawilo akutsogolo. Zitha kuwoneka kuti mapaipi aliwonse amtundu wapawiri-circuit hydraulic brake system alephera, silinda ya brake master imatha kugwirabe ntchito, koma sitiroko yofunikira imawonjezeka.
