ʻO ka master cylinder (Master Cylinder), ka mea i ʻike ʻia ʻo ka ʻaila nui (air), ʻo kāna hana nui ʻo ka hoʻokuke ʻana i ka wai hoʻoheheʻe (a i ʻole ke kinoea) e hoʻouna ʻia i kēlā me kēia pahu pahu e pana i ka piston.
ʻO ka pahu pahu pahu kahi ala hoʻokahi piston hydraulic cylinder, a ʻo kāna hana ʻo ka hoʻololi ʻana i ka hoʻokomo ʻana i ka ikehu mechanical e ka mīkini pedal i ka ikehu hydraulic. ʻElua mau ʻano o ka pahu pahu pahu, ke keʻena hoʻokahi a me ke keʻena ʻelua, i hoʻohana ʻia i loko o nā ʻōnaehana braking hydraulic a me nā ʻōnaehana pālua.
I mea e hoʻomaikaʻi ai i ka palekana o ka hoʻokele ʻana o nā kaʻa, e like me nā koi o nā lula kaʻa, ʻo ka ʻōnaehana braking service o nā kaʻa i kēia manawa ke hoʻohana nei i kahi ʻōnaehana braking ʻelua-circuit, kahi i haku ʻia me nā pūʻulu haku lua-chamber master cylinders (hoʻokahi-chamber brake. ua hoʻopau ʻia nā cylinders master). ʻōnaehana hoʻokele hydraulic ʻelua.
I kēia manawa, aneane ʻo nā ʻōnaehana braking hydraulic pālua ʻelua he ʻōnaehana braking servo a i ʻole ʻōnaehana braking ikaika. Eia nō naʻe, i kekahi mau kaʻa liʻiliʻi a māmā paha, i mea e maʻalahi ai ke ʻano, a ma lalo o ke ʻano ʻaʻole i ʻoi aku ka ikaika o ka pedal brake ma mua o ke ʻano o ka ikaika kino o ka mea hoʻokele, aia kekahi mau hiʻohiʻona e hoʻohana ana i ka tandem dual-chamber brake. master cylinder e hana i ka lua-circuit manual hydraulic brake. ʻōnaehana.
ʻO ka tandem keʻena ʻelua pahu pahu master cylinder
Hoʻohana ʻia kēia ʻano pahu pahu pahu pahu i loko o kahi ʻōnaehana brake hydraulic ʻelua-circuit, e like me ʻelua mau pahu pahu pahu pahu hoʻokahi i hoʻopili ʻia i ka moʻo.
Hoʻolako ʻia ka hale o ka pahu master brake me ka piston cylinder mua 7, kahi piston cylinder hope 12, kahi puna cylinder mua 21 a me kahi puna cylinder hope 18.
Hoʻopaʻa ʻia ka piston cylinder mua me kahi apo hoʻopaʻa 19; ua hoʻopaʻa ʻia ka piston cylinder hope me ke apo hoʻopaʻa 16, a ua hoʻonoho ʻia me ke apo hoʻopaʻa 13. Ua kamaʻilio ʻia nā waihona wai ʻelua me ke keʻena mua B a me ke keʻena hope A, a ua kamaʻilio ʻia me ka mua a me ka pahu huila hope. ma o ko lakou mau pahu puka aila pakahi 3. Hookuiia ka piston cylinder mua e ka ikaika hydraulic o ka piston cylinder hope, a me ka hope. hoʻokele pololei ʻia ka piston cylinder e ke koʻokoʻo pana. 15 pana.
I ka wā e hana ʻole ai ka pahu pahu pahu, ʻo ke poʻo piston a me ke kīʻaha ma ke keʻena mua a me hope aia wale nō ma waena o nā puka bypass 10 a me nā puka uku 11. ʻOi aku ka ikaika elastic o ka pūnāwai hoʻi o ka piston o ka pahu mua ma mua o ka pūnāwai hoʻi o ka piston o ka pahu hope e hōʻoia i ke kūlana kūpono o nā piston ʻelua ke hana ʻole.
I ka wā e hoʻopaʻa ai, hehi ka mea hoʻokele i ka pedal brake, hoʻouna ʻia ka ikaika pedal i ke koʻokoʻo pana 15 ma o ka mīkini hoʻouna, a hoʻokuke i ka piston cylinder hope 12 e neʻe i mua. Ma hope o ka uhi ʻana o ke kīʻaha ʻili i ka puka bypass, piʻi ke kaomi ma ka lua hope. Ma lalo o ka hana o ke kaomi hydraulic i loko o ke keʻena hope a me ka ikaika o ka pūnāwai o ka cylinder hope, ke neʻe nei ka piston 7 o ka cylinder mua, a piʻi pū ke kaomi i ka keʻena mua. Ke hoʻomau ʻia ka paʻi ʻana o ka pedal i lalo, e piʻi mau ana ke kaomi hydraulic ma mua a me nā keʻena hope, e hoʻoheheʻe ʻia ka mua a me ka hope.
Ke hoʻokuʻu ʻia ka pahu, hoʻokuʻu ka mea hoʻokele i ka pedal brake, ma lalo o ka hana o nā pūnāwai piston mua a hope, ʻo ka piston a me ke koʻokoʻo pahu i loko o ka pahu pahu pahu e hoʻi i ke kūlana mua, a ʻo ka ʻaila i loko o ka pipeline e pana i ka ʻaila. hoʻihoʻi valve 22 a hoʻi i hope Ua hoʻopaʻa ʻia ka master cylinder, i nalowale ka hopena braking.
Inā hāʻule ka pōʻaiapuni i hoʻomalu ʻia e ke keʻena mua, ʻaʻole i hoʻopuka ka piston cylinder mua i ke kaomi hydraulic, akā ma lalo o ka ikaika hydraulic o ka piston cylinder hope, ua hoʻokuʻu ʻia ka piston cylinder mua i ka hopena mua, a me ke kaomi hydraulic i hana ʻia e ka hope. Hiki i ke keʻena ke hana i ka huila hope e hana i ka ikaika braking. Inā hāʻule ke kaapuni i hoʻomalu ʻia e ke keʻena hope, ʻaʻole hoʻopuka ka keʻena hope i ke kaomi hydraulic, akā ke neʻe nei ka piston cylinder hope ma lalo o ka hana a ke koʻokoʻo pana, a hoʻopili i ka piston cylinder mua e pana i ka piston cylinder mua i mua, a me ka Hiki i ke keʻena mua ke hoʻohua i ke kaomi hydraulic i nā huila mua. Hiki ke ʻike ʻia i ka wā i pau ʻole ai nā laina paipu i loko o ka ʻōnaehana hoʻoheheʻe hydraulic ʻelua, hiki ke hana mau ka brake master cylinder, akā ua hoʻonui ʻia ka paʻi pedal i koi ʻia.
