Chii chiri kumanikidza mu brake system yemota?
Zviri mukati
Ndeipi kudzvinyirirwa mumabhureki ehydraulic emotokari dzinotakura vanhu?
Pakutanga, zvine musoro kuti tinzwisise pfungwa dzakadai sekumanikidzwa mu hydraulic system uye kudzvanywa kunoitwa nema calipers kana cylinder rods zvakananga pamabhureki pads.
Kudzvinyirirwa mu hydraulic system yemota pachayo muzvikamu zvayo zvese zvakangofanana uye pakukwirira kwayo mumotokari dzemazuva ano ndeye 180 bar (kana iwe uchiverenga mumhepo, saka iyi ingangoita 177 atm). Mumitambo kana mota dzinobhadhariswa veruzhinji, kudzvanywa uku kunogona kusvika ku200 bar.
Zvechokwadi, hazvibviri kugadzira zvakananga kudzvinyirira kwakadaro chete nekuedza kwesimba remuscular remunhu. Naizvozvo, pane maviri anosimbisa zvinhu mu braking system yemota.
- Pedal lever. Nekuda kweiyo lever, iyo inopiwa nekugadzirwa kweiyo pedal assembly, kudzvanywa kweiyo pedal yakatanga kushandiswa nemutyairi kunowedzera ne4-8 nguva, zvichienderana nerudzi rwemotokari.
- vacuum booster. Iyi gungano inowedzerawo kudzvanywa pane brake master cylinder nekanenge ka2. Kunyangwe magadzirirwo akasiyana eiyi unit achipa mutsauko wakakura mukuwedzera simba muhurongwa.
Muchokwadi, kumanikidza kwekushanda mumabhureki system panguva yakajairika yekushanda kwemotokari kashoma kudarika 100 atmospheres. Uye chete panguva yekukurumidzira mabhureki, munhu akakura zvakanaka anokwanisa kudzvanya tsoka pane pedal kugadzira kudzvanywa muhurongwa huri pamusoro pe100 atmospheres, asi izvi zvinoitika chete mune dzakasiyana zviitiko.
Kudzvinyirirwa kwecaliper piston kana cylinders inoshanda pamapadhi yakasiyana ne hydraulic pressure mu brake system. Pano musimboti wakafanana nemusimboti wekushanda kwechinyorwa che hydraulic press, apo chikamu chiduku chepombi cylinder inoputira mvura mucylinder yechikamu chikuru zvikuru. Kuwedzera kwesimba kunoverengerwa seyero ye cylinder diameters. Kana iwe ukateerera kune brake caliper piston yemotokari inotakura vanhu, ichave yakakura zvakapetwa mudhayamita kupfuura piston yebrake master silinda. Nokudaro, kudzvinyirirwa pamapadhi pachawo kuchawedzera nekuda kwekusiyana kwema cylinder diameters.
Air brake pressure
Nheyo yekushanda kweiyo pneumatic system yakati siyanei neiyo hydraulic system. Kutanga, kudzvinyirirwa pamapadhi kunogadzirwa nemhepo, kwete kudzvinyirira kwemvura. Chechipiri, mutyairi haagadziri kumanikidzwa nesimba remuscular yegumbo. Mhepo iri muunogamuchira inoputirwa necompressor, iyo inogamuchira simba kubva kune injini. Uye mutyairi, nekutsikirira bhureki pedal, anongovhura vharuvhu, iyo inoparadzira mweya unoyerera mumigwagwa mikuru.
Ivhavha yekugovera mupneumatic system inodzora kumanikidzwa kunotumirwa kumakamuri ekuputsa. Pamusana peizvi, simba rekumanikidza remapadhi kune madhiramu rinogadziriswa.
Iyo yakanyanya kudzvinyirira mumitsetse yepneumatic system kazhinji haipfuure 10-12 atmospheres. Iyi ndiyo dzvinyiriro iyo mugamuchiri akagadzirirwa. Zvisinei, simba rekumanikidza remapadhi kune madhiramu rakakwirira zvikuru. Kusimbisa kunoitika mu membrane (zvishoma kazhinji - piston) makamuri epneumatic, anoisa kumanikidza pamapedhi.
Iyo pneumatic brake system pamotokari yevafambi haiwanzo. Pneumatics iri kutanga kuoneka pakawanda pamotokari dzekushandisa kana marori madiki. Dzimwe nguva pneumatic mabhureki anodzokorora iwo hydraulic, ndiko kuti, iyo system ine maviri akaparadzana maseketi, ayo anoomesa dhizaini, asi anowedzera kuvimbika kwemabhureki.
