tsananguro

Mabhureki mabhureki, anonziwo mota mabhureki pads, anonongedzera kune friction material yakamisikidzwa padhiramu rebhureki kana bhureki disc inotenderera nemavhiri. Iwo friction linings uye friction linings anoiswa pasi pekumanikidzwa kwekunze uye anogadzira friction kuti awane chinangwa chekudzikisa mota.
Mota mabhureki pads anowanzo kuumbwa nesimbi ndiro, adhesive insulation layer uye friction block. Simbi ndiro inofanira kupendwa kudzivirira ngura. Iyo SMT-4 choto tembiricha tracker inoshandiswa kuona tembiricha kugoverwa kweiyo coating process kuti ive nechokwadi chemhando.
Nheyo yekushanda yebhureki inonyanya kubva kune friction. Iko kupokana pakati pemabhureki pads uye mabhureki discs (madhiramu) uye matayi uye pasi rinoshandiswa kushandura kinetic simba remotokari kuita frictional kupisa simba kumisa mota. Iyo yakanaka uye inoshanda mabhureki system inofanirwa kupa yakasimba, yakakwana uye inodzoreka braking simba, uye iine yakanaka hydraulic transmission uye kupisa kupisa masimba kuti ive nechokwadi chekuti simba rinoitwa nemutyairi kubva pabrake pedal rinogona kuendeswa zvizere uye zvinobudirira kune master cylinder Uye imwe neimwe. sub-cylinder, uye kudzivirira kutadza kwehydraulic uye kuparara kwemabhureki kunokonzerwa nekupisa kwakanyanya. Iyo mabhureki system pamota yakakamurwa kuita zvikamu zviviri: disc uye dhiramu, asi kunze kweiyo mutengo mukana, mabhureki edhiramu haashande zvakanyanya kupfuura disc mabhureki.
“Friction” inoreva kupikisa kwekufamba pakati penzvimbo dzinobata zvinhu zviviri zvinenge zviri kufamba. Iro frictional force (F) inoenzanirana nechigadzirwa chefiction coefficient (μ) uye vertical normal pressure (N) panzvimbo inotakura friction, inoratidzwa sechimiro chemuviri: F=μN. Kune iyo brake system: (μ) inoreva friction coefficient pakati pebrake pad nebhureki disc, uye N isimba rinoitwa nebrake caliper piston pabrake pad (Pedal Force). Iyo yakakura iyo friction coefficient, iyo yakakura friction inogadzirwa, asi iyo friction coefficient pakati pebhureki pad uye disc ichachinja nekuda kwekupisa kwakanyanya kunogadzirwa mushure mekupokana, kureva kuti, friction coefficient (μ) inoshanduka nekushisa Zvisinei, mhando yega yega yebrake pad ine akasiyana friction coefficient shanduko curve nekuda kwekusiyana kwezvinhu. Naizvozvo, akasiyana mabhureki mapedhi anozove neakasiyana akanyatsoshanda tembiricha uye anoshanda ekushanda tembiricha mazinga. Apa ndipo paunotenga mabrake pads. Zvaunofanira kuziva.
Transmission of braking force
Simba rinoitwa nebrake caliper piston pamabhureki pads rinonzi: Pedal Force. Mushure mekunge simba remutyairi riri pabhureki pedal rakwidziridzwa nerever of the pedal mechanism, simba racho rinowedzerwa nemusimboti wevacuum pressure musiyano kuburikidza nekuwedzera simba, iro rinoshandiswa kusunda brake master silinda. Iyo hydraulic pressure inogadzirwa nebrake master cylinder inoshandisa iyo incompressible power transmission effect, iyo inopfuudzwa kune imwe neimwe sub-cylinder kuburikidza ne brake hose, uye kudzvanywa kunowedzerwa ne "Pascal musimboti" kusundira piston ye sub-cylinder. kushandisa simba pamabhureki pads. “Mutemo waPascal” (Pascal’s Law) zvinoreva kuti dzvinyiriro yemvura panzvimbo ipi zvayo mumudziyo wakavharwa inofanana.
Kudzvinyirirwa kunowanikwa nekuparadzanisa simba rinoshandiswa nenzvimbo yekugamuchira simba. Kana kudzvinyirirwa kwakaenzana, tinogona kushandisa kushandura chiyero chenzvimbo dzakashandiswa uye dzekumanikidzira-kugamuchira nzvimbo kuti tiwane simba rekusimudzira simba (P1 = F1 / A1 = F2 / A2 = P2) . Inoshandiswa mubhureki system, chiyero chekumanikidzwa kweishe silinda kune silinda chiyero chenzvimbo yepiston ye master cylinder kunzvimbo yepiston yecylinder.
Akashongedzerwa ne: ABS
ABS: Anti-lock Brake System, sezvinoreva zita, i "Anti-lock Brake System". Wese munhu anoziva kuti mabhureki makuru anoitika pakarepo matai asati avharwa. Kana simba rekubhureki richikwanisa kuchengetedzwa pamwe nekukwesha kwevhiri, bhureki rakakura kwazvo rinowanikwa. Kana mabhureki ebhureki akakura kudarika kukweshwa kwevhiri, zvinoita kuti vhiri rivhare. Kana vhiri ravhara, kukweshana kuri pakati pevhiri nepasi kuchachinja kubva pa “static friction” kuenda ku “dynamic friction”. Kwete chete kupesana kunoderedzwa zvakanyanya, asi kutungamira kunorasika. Tracking kugona. Nekuti kuvharika kwevhiri kunokonzerwa nekuenzanisa pakati pesimba rekubhureki uye friction force pakati pevhiri nepasi, ndiko kuti, muganhu wekuti vhiri rinovharika mota ichimhanya zvinoenderana nehunhu hwevhiri. pachayo, mamiriro emugwagwa, kona yekumisikidza, uye simba rematayi.
Maitiro ekumisa system "akasiyana nguva nenguva". ABS inoshandisa ma sensors emotokari akaiswa pamavhiri mana kuona kana matai akakiyiwa, kubvisa zvinhu zvisina chokwadi zvepfungwa dzevanhu, uye kunyatso kudzora kuburitswa panguva yakakodzera kweiyo hydraulic pressure yebrake cylinder kudzivirira mabhureki kubva kukiya. . Yakawanda yeazvino ABS inotora dhizaini inogona kuramba ichitsika uye kuburitsa kagumi nembiri kusvika makumi matanhatu pasekondi (12~60 Hz). Kuenzaniswa ne3 kusvika ku6 nguva dzepamusoro nyanzvi dzemujaho, idanho repamusoro-soro rekuita.
Iyo yakakwirira iyo frequency yekutsika, iyo inowedzera Iyo simba rekubhureki rinogona kuchengetedzwa pamucheto padhuze nemuganhu. Kurongeka uye kuvimbika kunogona kuitwa neABS kwakapfuura miganhu yevanhu, saka tinoti: ABS ndiyo inonyanya kukosha-ye-mari michina kana uchitenga motokari. Kunyanya njodzi yehukama yeAir-Bag.
