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.
Pofuna kupititsa patsogolo chitetezo cha magalimoto, malinga ndi zofunikira za malamulo apamsewu, ma braking system agalimoto tsopano akutenga ma braking a dual-circuit braking system, omwe amapangidwa ndi ma silinda a master-chamber master (ma brake achipinda chimodzi). ma silinda apamwamba achotsedwa). 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 apange mawonekedwewo kukhala osavuta, komanso ngati mphamvu yoyendetsa ma brake sidutsa mphamvu yakuthupi ya dalaivala, palinso mitundu ina yomwe imagwiritsa ntchito mabuleki a tandem dual-chamber. master cylinder kuti apange 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 ya silinda yakumbuyo imasindikizidwa ndi mphete yosindikiza 16, ndipo imayikidwa ndi mphete yosungira 13. Malo awiri amadzimadzi amalumikizana motsatana ndi chipinda chakutsogolo B ndi chipinda chakumbuyo A, ndipo amalumikizidwa ndi ma cylinders akutsogolo ndi kumbuyo. kudzera mu mavavu awo otulutsira mafuta 3. Pistoni ya silinda yakutsogolo imakankhidwa ndi mphamvu ya hydraulic ya 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 yatulutsidwa, dalaivala amamasula chopondapo, pansi pa pisitoni yakutsogolo ndi yakumbuyo, pisitoni ndi ndodo yokankhira mu silinda ya brake master zimabwerera pomwe idayambira, ndipo mafuta omwe ali mupaipi amakankhira mafutawo. valavu yobwerera 22 ndikubwerera mmbuyo Silinda ya master imaphwanyidwa, kotero kuti braking effect idzatha.
Ngati dera loyang'aniridwa ndi chipinda chakutsogolo likulephera, pisitoni ya cylinder yakutsogolo sipanga hydraulic pressure, koma pansi pa mphamvu ya hydraulic ya pistoni yakumbuyo ya silinda, pisitoni ya silinda yakutsogolo imakankhidwira kumapeto, ndipo kuthamanga kwa hydraulic kumapangidwa ndi kumbuyo. chipinda akhoza kupanga gudumu kumbuyo kubala braking mphamvu. Ngati dera loyang'aniridwa ndi chipinda chakumbuyo likulephera, chipinda chakumbuyo sichimapanga kuthamanga kwa hydraulic, koma pisitoni ya cylinder yakumbuyo imasunthira kutsogolo pansi pakuchita kwa ndodo, ndikulumikizana ndi pisitoni ya silinda yakutsogolo kukankhira pisitoni yakutsogolo, ndipo kutsogolo chipinda akhoza kupanga Hydraulic kuthamanga mabuleki mawilo kutsogolo. Zitha kuwoneka kuti mapaipi aliwonse amtundu wapawiri-circuit hydraulic brake system alephera, silinda ya brake master imatha kugwirabe ntchito, koma sitiroko yofunikira imawonjezeka.
