Brake fluid. Zvinotyisa bvunzo mhinduro

Zvinoenderana neongororo yakaitwa neAutomotive Institute, ina kubva gumi pagumi DOT-4 mabhureki emvura haakwane mamwe maitiro. Mvura yakashata-yemhando inorebesa, uye muzviitiko zvakanyanyisa inogona kubvisa zvachose mota yekugona kudzika.

Iyo Materials Science Center yeInstitute of Road Transport yakaedza mhando yeDOT-4 mabhureki emvura yakakurumbira pamusika wePoland. Ongororo yemhando yekuteerera yakavhara gumi zvakakurumbira zvigadzirwa zvemotokari. ITS nyanzvi dzakatarisa, kusanganisira iyo yekubikira point value uye viscosity, i.e. parameters inotarisa kunaka kwemvura.

- Mhinduro dzebvunzo dzakaratidza kuti zvinwiwa zvina kubva pagumi hazvizadzise zvinodikanwa zvakatsanangurwa muyero. Zvinwiwa zvina zvakaratidza kuti nzvimbo yekubikira yaive yakadzikira, uye maviri acho akapotsa apera zvachose panguva yekuedzwa uye haana kuratidza kuramba oxidation. Muchiitiko chavo, makomba ane ngura aionekawo pazvinhu zvemurabhoritari,” anotsanangura kudaro Eva Rostek, mukuru weITS Materials Research Center.

Muchokwadi, kushandiswa kweakadaro (akaderera) mabhureki emvura anogona kuwedzera mileage uye, mumamiriro ezvinhu akanyanya, kuita kuti zvisaite kuti mota imire.

Brake fluid inorasikirwa nehupfumi hwayo nezera, saka vagadziri vemotokari vanokurudzira kuitsiva kamwechete pamakore maviri kusvika matatu. Pasinei neizvi, tsvakurudzo muna 2014 yakaratidza kuti 22 muzana ye Vatyairi vePoland havana kumbomutsiva, uye 27 muzana vakadaro. akatariswa mota, aive nekodzero yekuchinja nekukurumidza.

- Tinofanira kuyeuka kuti brake fluid is hygroscopic, i.e. inotora mvura kubva mumhoteredzo. Mvura shoma, iyo yakakwirira yemiganhu yekuvira uye yakakwirira kushanda kwekushanda. Nzvimbo yekubikira yeDOT-4 class liquid haifaniri kunge yakaderera kupfuura 230 ° C, uye DOT-5 class liquid haifaniri kunge yakaderera kupfuura 260 ° C, inoyeuchidza Eva Rostek kubva kuITS.

Mabhureki anobudirira ane mvura yemhando yepamusoro musystem anosvika pakukwanisa kwawo mumasekondi angangoita 0,2. Mukuita, izvi zvinoreva (kufunga kuti motokari inofamba 100 km/h inofamba chinhambwe che27 m/s) kuti braking haitangi kusvika mamita mashanu mushure mekunge brake yaiswa. Nemvura isingasangane nezvinodiwa, kureba kwebhureki kuchawedzera kusvika ka5, uye mota ichatanga kudzikira mumamita makumi matatu chete kubva panguva yaunodzvanya brake pedal!

Hunhu hwebhureki fluid hunokanganisa zvakananga kuchengetedza kwekutyaira, saka kana uchiisarudza, tevera kurudziro yevagadziri vemotokari uye tenga chete yakavharwa kurongedza.
