Iyo Yekushanda Nheyo Yesimba Brake Booster

Iyo vacuum booster inoshandisa musimboti wekuyamwa mumhepo kana injini iri kushanda, izvo zvinogadzira vacuum padivi rekutanga rebooster. Mukupindura mutsauko wekumanikidzwa kwemhepo yakajairika kune rumwe rutivi, mutsauko wekumanikidza unoshandiswa kusimbisa iyo braking thrust.

Kana paine kunyange diki diki mutsauko pakati pemativi maviri e diaphragm, nekuda kwenzvimbo yakakura ye diaphragm, kusunda kukuru kunogona kugadzirwa kusunda diaphragm kusvika kumagumo nekudzvinyirira kwakaderera. Kana mabhureki, vacuum booster system zvakare inodzora vacuum ichipinda mubooster kuita kuti diaphragm ifambe, uye inoshandisa tsvimbo yekusundidzira padiaphragm kubatsira munhu kutsika uye kusunda brake pedal kuburikidza neyakasanganiswa mudziyo wekutakura.

Munzvimbo isiri kushanda, chitubu chekudzoka chevharuvhu yekusundidzira tsvimbo inosundidzira vharuvhu yekusundidzira tsvimbo kune yekukiya chinzvimbo kurudyi, uye vacuum valve port iri munzvimbo yakashama. Chitubu chevharuvhu yekudzora inoita kuti kapu yevharuvhu yekudzora uye chigaro chevharuvhu yemhepo zvibatane, nekudaro ichivhara chiteshi chevhavha yemhepo.

Panguva ino, iyo vacuum gasi kamuri uye yekushandisa gasi kamuri yebooster inofambiswa neyekushandisa gasi kamuri chiteshi kuburikidza neyakavharira gasi kamuri chiteshi chepiston muviri kuburikidza nevhavhavhavha yekudzora, uye yakaparadzaniswa nemhepo yekunze. Mushure mekunge injini yatangwa, vacuum (negative pressure yejini) pane yakawanda yeinjini inokwira kusvika -0.0667mpa (kureva, kukosha kwemhepo ndeye 0.0333mpa, uye mutsauko wekumanikidzwa nemhepo yemhepo ndeye 0.0667mpa ). Zvadaro, iyo booster vacuum uye vacuum yekamuri yekunyorera yakawedzera kusvika -0.0667mpa, uye vaive vakagadzirira kushanda chero nguva.

Kana mabhureki, brake pedal inodzvinyirirwa, uye simba rekutsika rinokwidziridzwa nerevhisi uye rinoshanda patsvimbo yekusundidzira yevharuvhu yekudzora. Chekutanga, chitubu chekudzoka chekudzora vharafu kusunda tsvimbo inodzvanywa, uye yekudzora vharafu kusunda tsvimbo nemhepo vharafu mbiru inoenda kumberi. Kana iyo yekudzora vharafu inosundidzira tsvimbo inofamba ichienda kumberi kune iyo yekudzora kapu yevharuvhu inobata chigaro chevacuum valve, iyo vacuum valve port yakavharwa. Panguva ino, iyo booster vacuum uye kamuri yekushandisa inoparadzaniswa.

Panguva ino, kupera kwevharuvhu yemhepo inongosangana nepamusoro peiyo reaction disk. Sezvo control valve push rod ichiramba ichienda kumberi, air valve port inovhura. Mushure mekusefa kwemhepo, mhepo yekunze inopinda mukamuri yekunyorera yebooster kuburikidza neyakavhurika airvhavha chiteshi uye chiteshi chinotungamira kukamuri rekushandisa remhepo, uye simba re servo rinogadzirwa. Nekuda kwekuti zvinhu zvereaction plate zvine midziyo yemuviri inodiwa yeyakaenzana unit pressure pane yakatsikirirwa, simba reservo rinowedzera muchikamu chakatarwa (servo force ratio) nekuwedzera zvishoma nezvishoma kwekuisa simba rekudzora valve push rod. Nekuda kwekuganhurirwa kweiyo servo simba zviwanikwa, kana yakanyanya servo simba yasvika, kureva, kana iyo vacuum degree yekamuri yekunyorera iri zero, iyo servo force ichava isingachinji uye haizoshanduki zvakare. Panguva ino, simba rekupinza uye simba rekubuda rebooster richawedzera nehuwandu hwakafanana; kana bhureki radzimwa, rovaruvhu yekudzora tsvimbo inodzokera kumashure nekudzikira kwesimba rekupinza. Kana iyo yepamusoro yekusimudzira nzvimbo yasvika, mushure mekuvhurwa kwevhavhavhavha yevhavha, iyo booster vacuum uye yekunyorera kamuri yemhepo yakabatana, iyo vacuum dhigirii yekamuri yekunyorera inoderera, simba reservo richadzikira, uye piston muviri unodzokera kumashure. . Nenzira iyi, sezvo simba rekupinza richiderera zvishoma nezvishoma, simba re servo richaderera muchikamu chakatarwa (servo force ratio) kusvikira bhureki yasunungurwa zvachose.
