Iyo master silinda (Master Cylinder), inozivikanwawo seiyo brake main oil (mhepo), basa rayo guru nderekusundidzira brake fluid (kana gasi) kuti iendeswe kune imwe neimwe brake silinda kusunda piston.
Iyo brake master cylinder inzira imwe chete inobata piston hydraulic cylinder, uye basa rayo ndere kushandura iyo mechaniki simba rekuisa neanotsika meshini kuita hydraulic simba.Kune marudzi maviri emabrake master cylinders, single-chamber uye dual-chamber, ayo anoshandiswa zvakateerana mune imwechete-circuit uye dual-circuit hydraulic braking system.
Kuti uvandudze kuchengetedzeka kwekutyaira kwemotokari, zvinoenderana nezvinodiwa nemirairo yetraffic, iyo service braking system yemotokari ikozvino yatora mbiri-yedunhu braking system, iyo inoumbwa neakatevedzana maviri-chamber master silinda (single-chamber brake. master cylinders akabviswa).dual-circuit hydraulic braking system.
Parizvino, anenge ese maviri-edunhu hydraulic braking masisitimu ari servo braking masisitimu kana dynamic braking masisitimu.Nekudaro, mune dzimwe mota diki kana dzakareruka, kuitira kuti chimiro chive nyore, uye pasi pemamiriro ekuti brake pedal force haipfuure huwandu hwesimba remutyairi remuviri, kune zvakare mamwe mamodheru anoshandisa tandem dual-chamber brake. master cylinder kugadzira maviri-circuit manual hydraulic brake.system.
Tandem mbiri-chamber brake master silinda chimiro
Iyi mhando yebrake master silinda inoshandiswa mune mbiri-yedunhu hydraulic brake system, iyo yakaenzana neaviri-single-chamber mabhureki master silinda akabatana munhevedzano.
Imba yebrake master silinda ine kumberi silinda piston 7, rear cylinder piston 12, kumberi silinda chitubu 21 uye kumashure silinda chitubu 18.
Iyo yepamberi cylinder piston yakavharwa nemhete yekuisa chisimbiso 19;rear cylinder piston yakavharwa nemhete yekuisa chisimbiso 16, uye inogadzikwa nemhete inochengetedza 13. Iwo maviri emvura madhirigi anotaurirana nekamuri yekumberi B uye yekumashure kamuri A, uye anotaurirwa kumberi uye kumashure mabhureki mavhiri cylinders. kuburikidza nemavharuvhu avo ekubuda kwemafuta 3. Iyo yepamberi cylinder piston inosundirwa ne hydraulic force ye rear cylinder piston, uye rear cylinder piston inofambiswa zvakananga ne push rod.15 kusunda.
Kana iyo brake master cylinder isiri kushanda, musoro wepiston nekapu kumberi nekumashure makamuri zvinongowanikwa pakati peakasiyana maburi maburi 10 uye maburi emuripo 11.Simba rinoputika rechitubu chekudzoka kwepiston yecylinder yepamberi yakakura kudarika iyo yekudzoka kwechitubu chepiston yecylinder yekumashure kuti ive nechokwadi chokuti mapistoni maviri ari panzvimbo yakarurama kana asiri kushanda.
Kana mabhureki, mutyairi anotsika pabhureki pedal, simba rinofambiswa ku push rod 15 kuburikidza ne transmission mechanism, uye anosaidzira silinda piston 12 yekumashure kuti ienderere mberi.Mushure mekunge kapu yematehwe yakavhara gomba rekupfuura, kudzvanywa mugomba rekumashure kunowedzera.Pasi pechiito che hydraulic pressure mukamuri rekumashure uye simba remvura remashure cylinder, piston 7 ye cylinder yepamberi inoenda mberi, uye kudzvinyirira muimba yepamberi kunowedzerawo.Kana iyo brake pedal ikaramba ichitsikirirwa pasi, iyo hydraulic pressure kumberi nekumashure makamuri inoramba ichiwedzera, ichiita mabhureki emberi nekumashure.
Kana bhureki raburitswa, mutyairi anoburitsa brake pedal, pasi pekuita kwemberi nekumashure zvitubu zvepiston, piston netsvimbo yekusundidzira mubrake master cylinder zvinodzokera panzvimbo yekutanga, uye mafuta ari mupombi anosaidzira kuvhura mafuta. kudzoka vharafu 22 uye inoyerera kumashure Iyo master cylinder yakabhurwa, kuitira kuti iyo braking effect iparare.
Kana dunhu rinodzorwa nekamuri yekumberi rikatadza, pamberi silinda piston haiburitse hydraulic pressure, asi pasi pesimba re hydraulic rear cylinder piston, pamberi silinda piston inosundirwa kumberi kumagumo, uye iyo hydraulic pressure inogadzirwa nekumashure. chamber anogona achiri kuita reshure vhiri kubereka braking simba.Kana dunhu rinodzorwa nekamuri rekumashure rikatadza, kamuri yekumashure haiburitse hydraulic pressure, asi rear cylinder piston inoenda kumberi pasi pechiito chetsvimbo yekusundidzira, uye inobata pamberi pecylinder piston kusundira pamberi silinda piston kumberi, uye iyo kamuri yekumberi inogona kuramba ichiburitsa Hydraulic pressure mabhureki mavhiri epamberi.Zvinogona kuoneka kuti kana chero seti yemapaipi mune mbiri-yedunhu hydraulic brake system ikatadza, brake master silinda inogona kushanda, asi inodiwa pedal sitiroko inowedzerwa.
