Wonjezerani mphamvu ya pedal ya mabuleki
Ngati mukanikiza kwambiri brake koma simungathe kutseka tayala, ndiye kuti pedal sipanga mphamvu yokwanira yotsekera, zomwe ndi zoopsa kwambiri. Galimoto yokhala ndi mphamvu yochepa kwambiri ya brake imatsekabe ikakanikizidwa mwamphamvu, koma imatayanso mphamvu yotsatirira. Malire a brake amapezeka nthawi yomwe brake isanatseke, ndipo woyendetsa ayenera kukhala ndi mphamvu yosunga brake pedal pamlingo uwu wa mphamvu. Kuti muwonjezere mphamvu ya brake pedal, choyamba mutha kuwonjezera chipangizo chothandizira mphamvu ya brake ndikuchisintha kukhala Air-Tank yayikulu. Komabe, kuchuluka kwa mphamvu yowonjezerera ndi kochepa, chifukwa mphamvu yowonjezera ya vacuum assistant idzapangitsa brake kutaya kupita patsogolo kwake, ndipo brake idzakanikizidwa mpaka kumapeto. Mwanjira imeneyi, woyendetsa sangathe kuwongolera brake bwino komanso mokhazikika. Chabwino ndikusintha pampu yayikulu ndi sub-pump, pogwiritsa ntchito mfundo ya PASCAL kuti muwongolere mphamvu ya brake pedal. Mukayikanso pampu ndi cholumikizira, kukula kwa disc kumatha kuwonjezeka nthawi yomweyo. Mphamvu ya braking ndi kukangana komwe kumachitika chifukwa cha brake pad ndi mphamvu yomwe imagwiritsidwa ntchito pa wheel shaft, kotero kukula kwa diski kukakhala kwakukulu, mphamvu ya braking imakhala yayikulu.
Kuziziritsa kwa mabuleki
Kutentha kwambiri ndiye chifukwa chachikulu cha kuwonongeka kwa mabuleki, kotero kuziziritsa mabuleki kumakhala kofunikira kwambiri. Pa mabuleki a ma disc, mpweya woziziritsa uyenera kulowetsedwa mwachindunji mu chogwirira. Chifukwa chifukwa chachikulu cha kuchepa kwa mabuleki ndi chifukwa cha kuwira kwa mafuta a mabuleki mu chogwirira, monga kudzera mu payipi yoyenera kapena kudzera mu kapangidwe kapadera ka gudumu poyendetsa mpweya woziziritsa mu chogwirira. Kuphatikiza apo, ngati mphamvu yotaya kutentha ya mphete yokha ili yabwino, imatha kugawananso gawo la kutentha kuchokera ku mbale ndi chogwirira. Ndipo kuyika chizindikiro, kubowola kapena kapangidwe ka mpweya wofewa kwa diski yofewa kumatha kusunga mphamvu yokhazikika ya mabuleki ndikupewa kutsetsereka kwa fumbi lachitsulo lotentha kwambiri pakati pa brake pad ndi diski, ndikuwonetsetsa bwino mphamvu ya mabuleki.
Koyenera ya kukangana
Chizindikiro chofunikira kwambiri cha magwiridwe antchito a mabuleki ndi friction coefficient. Miyezo ya dziko lonse imati brake friction coefficient ndi pakati pa 0.35 ndi 0.40. brake pad friction coefficient yoyenerera ndi yapakati komanso yokhazikika, ngati friction coefficient ndi yotsika kuposa 0.35, brake idzapitirira mtunda wotetezeka wa brake kapena ngakhale kulephera kwa brake, ngati friction coefficient ndi yokwera kuposa 0.40, brake ndi yosavuta kutseka mwadzidzidzi, ngozi yozungulira.
Ogwira ntchito yowunikira a National Non-metallic Mineral Products Quality Supervision and Inspection Center: "Muyezo wa dziko lonse ukunena kuti coefficient ya friction ya madigiri 350 iyenera kukhala yoposa 0.20
